ST-Segment Elevation Myocardial Infarction Following Transcatheter Aortic Valve Replacement.

J Am Coll Cardiol 2021 May;77(17):2187-2199

Hospital Universitario Ramón y Cajal, Madrid, Spain.

Background: Among patients with acute coronary syndrome following transcatheter aortic valve replacement (TAVR), those presenting with ST-segment elevation myocardial infarction (STEMI) are at highest risk.

Objectives: The goal of this study was to determine the clinical characteristics, management, and outcomes of STEMI after TAVR.

Methods: This was a multicenter study including 118 patients presenting with STEMI at a median of 255 days (interquartile range: 9 to 680 days) after TAVR. Procedural features of STEMI after TAVR managed with primary percutaneous coronary intervention (PCI) were compared with all-comer STEMI: 439 non-TAVR patients who had primary PCI within the 2 weeks before and after each post-TAVR STEMI case in 5 participating centers from different countries.

Results: Median door-to-balloon time was higher in TAVR patients (40 min [interquartile range: 25 to 57 min] vs. 30 min [interquartile range: 25 to 35 min]; p = 0.003). Procedural time, fluoroscopy time, dose-area product, and contrast volume were also higher in TAVR patients (p < 0.01 for all). PCI failure occurred more frequently in patients with previous TAVR (16.5% vs. 3.9%; p < 0.001), including 5 patients in whom the culprit lesion was not revascularized owing to coronary ostia cannulation failure. In-hospital and late (median of 7 months [interquartile range: 1 to 21 months]) mortality rates were 25.4% and 42.4%, respectively (20.6% and 38.2% in primary PCI patients), and estimated glomerular filtration rate <60 ml/min (hazard ratio [HR]: 3.02; 95% confidence interval [CI]: 1.42 to 6.43; p = 0.004), Killip class ≥2 (HR: 2.74; 95% CI: 1.37 to 5.49; p = 0.004), and PCI failure (HR: 3.23; 95% CI: 1.42 to 7.31; p = 0.005) determined an increased risk.

Conclusions: STEMI after TAVR was associated with very high in-hospital and mid-term mortality. Longer door-to-balloon times and a higher PCI failure rate were observed in TAVR patients, partially due to coronary access issues specific to the TAVR population, and this was associated with poorer outcomes.

Analytical assessment and performance of the 0/3h algorithm with novel high sensitivity cardiac troponin I.

Clin Chim Acta 2021 Apr 8;519:111-117. Epub 2021 Apr 8.

Département de Cardiologie, CHU Montpellier, Univ Montpellier 1, Montpellier F-34195 cédex 5, France.

Background: Recently, Ortho Clinical Diagnostics have launched a high sensitivity cardiac troponin I assay adapted on Vitros3600 / 5600. We aimed at evaluating the analytical and clinical performances using the 0/3-hour algorithm, of the Ortho hs-cTnI assay on the Vitros 3600® (Ortho Clinical Diagnostics, Illkirch, France) analyzer with comparison to Roche hs-cTnT assay on the Cobas8000/e801® module (Roche diagnostics, Meylan, France) and the Abbott STAT hs-cTnI assay on the Alinity i® (Abbott, Rungis, France) analyzer.

Methods: Imprecision studies, linearity, limit of detection, and the interference to hemolysis were performed for Ortho hs-cTnI assay. The concordance study was based on results of troponin obtained from 160 patients with chest pain to the emergency department. Testing was performed simultaneously measuring the Roche hs-cTnT and the Ortho hs-cTnI, then on remaining sample the concentration of Abbott hs-cTnI (n = 150). We applied the 0/3h algorithm to rule out/rule in, in acute myocardial infarction.

Results: Analytical performances were acceptable and in accordance with manufacturer's data. For late presenters 100, 92.8 and 88.8% patients could be rule-out with Roche, Ortho and Abbott assay, respectively with one NSTEMI missed with both hs-TnI assays. Applying the hs-cTn cut-offs from 0/3-hour algorithm, 107 (66.8%) could be rule out with Roche hs-cTnT with no AMI missed (sensitivity 100% [95%CI: 90.5 to 100] and NPV 100%); 89 with Ortho hs-cTnI (sensitivity 97.3% [95%CI: 85.8-99.9] and NPV 98.8% [95%CI:92.7-99.8]); and 61 with Abbott hs-cTnI (sensitivity 97% [95%CI: 84.2-99.9] and NPV 98.4% [95%CI: 89.8-99.7]). For rule-in, 23.7% (n = 37) from the total population would be designated in this group, with a specificity of 86.9% (95%CI: 79.7-92.4) and PPV of 69.8% (95%CI: 59.4-78.5) vs specificity of 72.3% (95%CI:63.5-80.0) and PPV of 51.4% (95%CI: 44.1-58.2)with Roche hs-cTnT vs Ortho hs-cTnI respectively; and with Abbott, 33 patients had constitued this group with a specificity of 52.1% (95%CI:42.7-61.4) and PPV of 36.4% (95%CI: 32.0-41.0).

Conclusion: In conclusion, according to ESC guidelines, our results indicate that the Ortho hs-cTnI assay for the Vitros 3600 instrument is a method that may be used in the clinical practice using 0/3-hour algorithm.

Idarucizumab (Praxbind) for dabigatran reversal in patients undergoing heart transplantation: a cohort of ten patients.

Future Sci OA 2021 Feb 15;7(4):FSO689. Epub 2021 Feb 15.

Department of Cardiology, Montpellier University Hospital, Montpellier Cedex 5, 34295, France.

Background: Novel oral anticoagulants are used in atrial fibrillation. Idarucizumab has been approved for reversal of dabigatran in situations of life-threatening hemorrhage or emergency surgery.

Objectives: We report a single center experience of ten patients on dabigatran therapy who were given idarucizumab prior to heart transplantation.

Methods & Results: The mean plasma concentration of dabigatran prior to reversal was 139 ± 89 ng/ml. Hemoglobin, hematocrit and platelet levels were decreased after surgery. Surgical procedures were successfully performed with no increased risk, especially regarding bleeding complications. All patients were alive after 90 days.

Conclusion: Dabigatran reversal with idarucizumab in contexts of emergency surgery/urgent procedures is an attractive and safe option to be taken into consideration for patients with end stage heart disease awaiting transplantation and indication of anticoagulant therapy.

Conception and bicentric validation of the proSCANNED score, a simplified bedside prognostic score for Heart Failure patients.

Sci Rep 2021 Mar 17;11(1):6179. Epub 2021 Mar 17.

Department of Cardiology, Montpellier University Hospital, CHRU Arnaud de Villeneuve, 371 avenue du Doyen Gaston Giraud, 34295, Montpellier Cedex 5, France.

A simple and accurate prognostic tool for Heart Failure (HF) patients is critical to improve follow-up. Different risk scores are accurate but with limited clinical applicability. The current study aims to derive and validate a simple predictive tool for HF prognosis. French outpatients with stable HF of two university hospitals were included in the derivation (N = 134) or in the validation (N = 274) sample and followed up for a median of 23 months. Potential predictors were variables with known association with mortality and easily available. The proSCANNED risk score was derived using a parametric survival model on complete case data; it includes 8 binary variables and its values are 0-8. In the validation sample, the ability of the score to discriminate the 1-year vital status was moderate (AUC = 0.71, IC95% = [0.64-0.71]). However, the stratification of the score in three groups showed a good calibration for patients in the low- and medium-risk risk group. The proSCANNED score is an easy-to-use tool in clinical practice with a good discrimination, stability, and calibration sufficient to improve the medical care of patients. Other follow up studies are necessary to assess score applicability in larger populations, and its impact.

Transcatheter aortic valve replacement performed with selective telemetry monitoring: A prospective study.

Int J Cardiol 2021 May 20;330:158-163. Epub 2021 Feb 20.

Department of Cardiology, CHU Montpellier, Montpellier University, Montpellier, France. Electronic address:

Background: Telemetry monitoring (TM) with or without intensive care unit (ICU) admission is the standard of care after Transcatheter aortic valve replacement (TAVR). Regarding to improvements of the technique and procedural results, TM may be considered only in selected patients. We aimed to confirm feasibility and safety of selective TM in patients undergoing TAVR.

Methods: We prospectively evaluated 449 consecutive patients undergoing TAVR. Patients were transferred to general cardiology ward (GCW) without TM after the procedure when stable clinical state, transfemoral access, no baseline right bundle branch block (RBBB), left ventricular ejection fraction (LVEF) > 40%, and no complication including any electrocardiogram (ECG) change within 1 h after the procedure ("low-risk" group). Others patients were considered for TM in ICU ("high-risk" group). The primary endpoint evaluated in-hospital major adverse events after unit admission according to VARC-2 criteria.

Results: The mean age was 81.8 ± 7.5 years and mean EuroSCORE II was 7.5 ± 4.8%. In total, 116 patients (25.8%) were considered as "low-risk" patients and 163 patients (36.3%) were referred to GCW, including those with immediate pacemaker implantation. A total of 96 patients (21.3%) reached the primary endpoint including mainly conductive disorders (12.8%). No major adverse events, particularly no late severe conductive disorder, occurred in the "low-risk" group (negative predictive value of 100%). Baseline RBBB (p < 0.01), LVEF < 40% (p = 0.02) and "high-risk" group (p < 0.01) were predictive of outcomes.

Conclusions: Using rigorous periprocedural selection criteria, patients' admission in GCW without TM can be routinely and safely performed in 1/3 of patients after TAVR.

Life-threatening arrhythmias in anterior ST-segment elevation myocardial infarction patients treated by percutaneous coronary intervention: adverse impact of morphine.

Eur Heart J Acute Cardiovasc Care 2020 Oct 14. Epub 2020 Oct 14.

Université de Strasbourg, Pôle d'Activité Médico-Chirurgicale Cardio-Vasculaire, Nouvel Hôpital Civil, Centre Hospitalier Universitaire, BP 426, 67091 Strasbourg, France.

Aims: Important controversies remain concerning the determinants of life-threatening arrhythmias during ST-segment elevation myocardial infarction (STEMI) and their impact on late adverse events. This study sought to investigate which factors might facilitate ventricular tachycardia (VT) and ventricular fibrillation (VF), in a homogeneous population of anterior STEMI patients defined by abrupt left anterior descending coronary artery (LAD) occlusion and no collateral flow.

Methods And Results: The 967 patients, who entered into the CIRCUS (Does Cyclosporine ImpRove Clinical oUtcome in ST elevation myocardial infarction patients) study, were assessed for further analysis. Acute VT/VF was defined as VT (run of tachycardia >30 s either self-terminated or requiring electrical/pharmacological cardioversion) or VF documented by electrocardiogram or cardiac monitoring, during transportation to the cathlab or initial hospitalization. VT/VF was documented in 136 patients (14.1%). Patients with VT/VF were younger and had shorter time from symptom onset to hospital arrival. Site of LAD occlusion, thrombus burden, area at risk, pre-percutaneous coronary intervention Thrombolysis in Myocardial Infarction flow, and ST-segment resolution were similar to that of patients without VT/VF. There was no impact of VT/VF on left ventricular remodelling or clinical outcomes. By multivariate analysis, the use of morphine (odds ratio 1.71; 95% confidence interval (1.13-2.60); P = 0.012) was the sole independent predictor of VT/VF occurrence.

Conclusions: In STEMI patients with LAD occlusion, our findings support the view that morphine could favour severe ventricular arrhythmias.

Diagnosis and Treatment of Iron Deficiency in Heart Failure: OFICSel study by the French Heart Failure Working Group.

ESC Heart Fail 2021 Apr 22;8(2):1509-1521. Epub 2021 Feb 22.

Department of Cardiology, Referral Centre for Cardiac Amyloidosis, CHU Henri Mondor, AP-HP, Créteil, France.

Aims: Iron deficiency (ID) occurs in about 50% of patients with heart failure (HF). The European Society of Cardiology (ESC) recommends ID diagnostic testing in newly diagnosed patients with HF and during follow-up, with intravenous iron supplementation (IS) only recommended in patients with HF with reduced ejection fraction (HFrEF). This study aimed to assess prevalence, clinical characteristics, and application of ESC guidelines for ID and IS in patients with HF in the real-life clinical setting.

Methods And Results: The French transversal multicentre OFICSel registry (300 cardiologists) conducted in 2017 included patients hospitalized for HF at least once in the previous 5 years. Diverse adult patients were eligible including inpatients and outpatients and those with acute and chronic HF. Data were collected from cardiologists and patients using study-specific surveys. Data included demographic and clinical data, as well as HF and ID management data. Overall, 2822 patients, mainly male (69.3%) with a median age of 69 years (interquartile range 58-78), were included. A total of 1075 patients (38.1%) were tested for ID, with 364 (33.9%) diagnosed. Of these, 168 (46.2%) received IS: 128 (76.2%) intravenous IS and 40 (23.8%) oral. Among the 201 patients with HFrEF diagnosed with ID, 99 (49.3%) received IS: 79 (79.8%) intravenous IS and 20 (20.2%) oral.

Conclusions: In clinical practice, only one-third of patients with HF had a diagnostic test for ID. In patients with ID with HFrEF, only 39.3% received intravenous IS as recommended. Thus, in general, cardiologists should be encouraged to follow the ESC guidelines to ensure optimal treatment for patients with HF.

Colchicine for Left Ventricular Infarct Size Reduction in Acute Myocardial Infarction: A Phase II, Multicenter, Randomized, Double-Blinded, Placebo-Controlled Study Protocol - The COVERT-MI Study.

Cardiology 2021 12;146(2):151-160. Epub 2021 Feb 12.

Centre d'Investigation Clinique, Inserm 1407, CarMeN Unit Inserm 1060, Hôpital Cardiologique Louis Pradel, Hospices Civils de Lyon, Université Claude Bernard Lyon 1, Bron, France,

Inflammatory processes have been identified as key mediators of ischemia-reperfusion injury in ST-segment elevation myocardial infarction (STEMI). They add damage to the myocardium and are associated with clinical adverse events (heart failure and cardiovascular death) and poor myocardial recovery. Colchicine is a well-known alkaloid with potent anti-inflammatory properties. In a proof-of-concept phase II trial, colchicine has been associated with a significant 50% reduction of infarct size (assessed by creatine kinase levels) in comparison to placebo in acute STEMI patients referred for primary percutaneous coronary intervention (PPCI). The Colchicine in STEMI Patients Study (COVERT-MI) is an ongoing confirmative prospective, multicenter, randomized, double-blind trial testing whether a short course oral treatment with colchicine versus placebo decreases myocardial injury in patients presenting with STEMI referred for PPCI. Adult patients, with a first STEMI episode and an initial TIMI flow ≤1, referred for PPCI, will be randomized (n = 194) in a 1:1 ratio to receive an oral bolus of colchicine of 2 mg followed by 0.5 mg b.i.d. treatment during 5 days or matching placebo. The primary endpoint will be the reduction in infarct size as assessed by cardiac magnetic resonance at 5 ± 2 days between both groups. The main secondary endpoints will be tested between groups in hierarchical order with left ventricular ejection fraction at 5 days, microvascular obstruction presence at 5 days, and absolute adverse left ventricular remodeling between 5 days and 3 months. This academic study is being financed by a grant from the French Ministry of Health (PHRCN-16-0357). Results from this study will contribute to a better understanding of the complex pathophysiology underlying myocardial injury after STEMI. The present study describes the rationale, design, and methods of the trial.

Pheochromocytoma in a patient presenting with ventricular fibrillation and carotid dissection: a case report.

Eur Heart J Case Rep 2021 Feb 4;5(2):ytab012. Epub 2021 Feb 4.

Department of Cardiology, CHU Montpellier, Montpellier University, Arnaud de Villeneuve Hospital, 371 Avenue du doyen Gaston Giraud, 34295 Montpellier, France.

Background: Pheochromocytoma is an endocrine tumour secreting catecholamines, most often revealed by clinical symptoms (headache, palpitations, diaphoresis, or resistant hypertension). Some cases of ventricular arrhythmias were described in the literature, without any formal link between arrhythmia and pheochromocytoma.

Case Summary: We report a case of pheochromocytoma discovered after cardiac arrest due to ventricular fibrillation in a 46-year-old patient. The diagnosis was suggested by clinical symptoms (headache, palpitation, and diaphoresis) and suspected on the abdominal computed tomography scan. The diagnosis was corroborated by metaiodobenzylguanidine scintigraphy and finally confirmed by anatomopathological analysis of the operative specimen. The cerebral imaging showed a dissection of the left internal carotid artery and an intraparenchymal haematoma that might be secondary to a catecholaminergic discharge of phaeochromocytoma and severe hypertension.

Discussion: Since pheochromocytoma is accessible to curative treatment, its detection in case of cardiac arrest is essential to decrease the risk of arrhythmic recurrence.

A New Requirement for Publication: Access to Effective Drugs for Ethical Reasons, The Example of Heart Failure.

ESC Heart Fail 2021 Apr 9;8(2):799-801. Epub 2021 Feb 9.

Institut Cœur Poumon, Centre Hospitalier Universitaire de Lille, Lille, France.

The past decade has witnessed the publication of many trials in the field of heart failure, several of which have demonstrated that new drugs could potentially reduce major cardiac events and sometimes even decrease total mortality. Most medical practitioners have experimented with withdrawal of the drug under investigation, having no knowledge of what the patient had received, consistent with a blinded design. In some such cases, the patient's clinical status may be rapidly compromised after withdrawal, suggesting (i) that the patient had been receiving the active drug and (ii) that the drug under investigation might exert beneficial effects. The patients should receive early benefit from the drug, but they are left most often without this beneficial treatment not only until the trial results are complete but also until after the guidelines are updated and after the reimbursement (months to years after the results). Here, we propose that the study sponsor should plan from study conception that all participating patients (regardless of whether they are in the placebo or active drug group) will have access to the drug upon trial completion-once safety is verified and until the results are known. Nowadays, it is not conceivable to submit the results of a large trial for publication without approval from a suitable ethical committee. Similarly, the access to the effective drug should be considered as a requirement for clinical research, not only for ethics committee approval, and for the registration of the trial in an international database until publication.

Pharmacogenomics of the Efficacy and Safety of Colchicine in COLCOT.

Circ Genom Precis Med 2021 Apr 9;14(2):e003183. Epub 2021 Feb 9.

PhyMedExp (Physiologie et Médecine Expérimentale du Coeur et des Muscles), Université de Montpellier, INSERM, Centre National de la Recherche Scientifique, Cardiology Department, CHU de Montpellier, France (F.R.).

Background: The randomized, placebo-controlled COLCOT (Colchicine Cardiovascular Outcomes Trial) has shown the benefits of colchicine 0.5 mg daily to lower the rate of ischemic cardiovascular events in patients with a recent myocardial infarction. Here, we conducted a post hoc pharmacogenomic study of COLCOT with the aim to identify genetic predictors of the efficacy and safety of treatment with colchicine.

Methods: There were 1522 participants of European ancestry from the COLCOT trial available for the pharmacogenomic study of COLCOT trial. The pharmacogenomic study's primary cardiovascular end point was defined as for the main trial, as time to first occurrence of cardiovascular death, resuscitated cardiac arrest, myocardial infarction, stroke, or urgent hospitalization for angina requiring coronary revascularization. The safety end point was time to the first report of gastrointestinal events. Patients' DNA was genotyped using the Illumina Global Screening array followed by imputation. We performed a genome-wide association study in colchicine-treated patients.

Results: None of the genetic variants passed the genome-wide association study significance threshold for the primary cardiovascular end point conducted in 702 patients in the colchicine arm who were compliant to medication. The genome-wide association study for gastrointestinal events was conducted in all 767 patients in the colchicine arm and found 2 significant association signals, one with lead variant rs6916345 (hazard ratio, 1.89 [95% CI, 1.52-2.35], =7.41×10) in a locus which colocalizes with Crohn disease, and one with lead variant rs74795203 (hazard ratio, 2.51 [95% CI, 1.82-3.47]; =2.70×10), an intronic variant in gene . The interaction terms between the genetic variants and treatment with colchicine versus placebo were significant.

Conclusions: We found 2 genomic regions associated with gastrointestinal events in patients treated with colchicine. Those findings will benefit from replication to confirm that some patients may have genetic predispositions to lower tolerability of treatment with colchicine.

Long term pronostic value of suPAR in chronic heart failure: reclassification of patients with low MAGGIC score.

Clin Chem Lab Med 2021 Feb 3. Epub 2021 Feb 3.

Department of Biochemistry, Centre Ressources Biologiques de Montpellier, University Hospital of Montpellier, Montpellier, France.

Objectives: Inflammation is a hallmark of heart failure (HF) and among inflammatory biomarkers, the most studied remains the C-reactive protein (CRP). In recent years several biomarkers have emerged, such as sST2 and soluble urokinase-type plasminogen activator receptor (suPAR). This study set out to examine the relative importance of long-time prognostic strength of suPAR and the potential additive information on patient risk with chronic HF in comparison with pronostic value of CRP and sST2.

Methods: Demographics, clinical and biological variables were assessed in a total of 182 patients with chronic HF over median follow-up period of 80 months. Inflammatory biomarkers (i.e., CRP, sST2, and suPAR) were performed.

Results: In univariate Cox regression analysis age, NYHA class, MAGGIC score and the five biomarkers (N-terminal pro brain natriuretic peptide [NT-proBNP], high-sensitive cardiac troponin T [hs-cTnT], CRP, sST2, and suPAR) were associated with both all-cause and cardiovascular mortality. In the multivariate model, only NT-proBNP, suPAR, and MAGGIC score remained independent predictors of all-cause mortality as well as of cardiovascular mortality. Risk classification analysis was significantly improved with the addition of suPAR particularly for all-cause short- and long-term mortality. Using a classification tree approach, the same three variables could be considered as significant classifier variables to predict all-cause or cardiovascular mortality and an algorithm were reported. We demonstrated the favorable outcome associated with patients with a low MAGGIC score and a low suPAR level by comparison to patients with low MAGGIC score but high suPAR values.

Conclusions: The main findings of our study are (1) that among the three inflammatory biomarkers, only suPAR levels were independently associated with 96-month mortality for patients with chronic HF and (2) that an algorithm based on clinical score, a cardiomyocyte stress biomarker and an inflammatory biomarker could help to a more reliable long term risk stratification in heart failure.

Non-alcoholic fatty liver disease and heart failure with preserved ejection fraction: from pathophysiology to practical issues.

ESC Heart Fail 2021 Apr 3;8(2):789-798. Epub 2021 Feb 3.

Department of Cardiology, Institute CARDIOMET, CHU-Toulouse, Toulouse, France.

The prevalence of non-alcoholic fatty liver disease (NAFLD) in heart failure (HF) preserved left ventricular ejection fraction (HFpEF) patients could reach 50%. Therefore, NAFLD is considered an emerging risk factor. In 20% of NAFLD patients, the condition progresses to non-alcoholic steatohepatitis (NASH), the aggressive form of NAFLD characterized by the development of fibrosis in the liver, leading to cirrhosis. The purpose of this review is to provide an overview of the relationships between NAFLD and HFpEF and to discuss its impact in clinical setting. Based on international reports published during the past decade, there is growing evidence that NAFLD is associated with an increased incidence of cardiovascular diseases, including impaired cardiac structure and function, arterial hypertension, endothelial dysfunction, and early carotid atherosclerosis. NAFLD and HFpEF share common risk factors, co-morbidities, and cardiac outcomes, in favour of a pathophysiological continuum. Currently, NAFLD and NASH are principally managed with non-specific therapies targeting insulin resistance like sodium-glucose co-transporter-2 inhibitors and liraglutide, which can effectively treat hepatic and cardiac issues. Studies including HFpEF patients are ongoing. Several specific NAFLD-oriented therapies are currently being developed either alone or as combinations. NAFLD diagnosis is based on a chronic elevation of liver enzymes in a context of metabolic syndrome and insulin resistance, with fibrosis scores being available for clinical practice. In conclusion, identifying HF patients at risk of NAFLD is a critically important issue. As soon as NAFLD is confirmed and its severity determined, patients should be proposed a management focused on symptoms and co-morbidities.

Low-dose colchicine prevents sympathetic denervation after myocardial ischemia-reperfusion: a new potential protective mechanism.

Future Sci OA 2020 Nov 23;7(2):FSO656. Epub 2020 Nov 23.

Department of Cardiology, Montpellier University Hospital, Montpellier, Occitanie, France.

Purpose: To evaluate the impact of colchicine on sympathetic denervation after acute myocardial infarction (AMI).

Materials & Methods: Ischemia/Reperfusion was induced in C57BL/6J male mice. Left coronary artery was ligated during 45 min followed by reperfusion. 400 μg/kg of colchicine or the placebo was administrated intraperitoneally 15 min before the reperfusion.

Results: Colchicine treatment significantly improved heart rate variability index after AMI. Colchicine prevented sympathetic denervation in the remote area (p = 0.04) but not in the scar area (p = 0.70).

Conclusion: These results suggest promising protective pathway of colchicine after AMI.

PRADOC: a trial on the efficiency of a transition care management plan for hospitalized patients with heart failure in France.

ESC Heart Fail 2021 Apr 25;8(2):1649-1655. Epub 2020 Dec 25.

Department of Cardiology, Montpellier University Hospital, Montpellier Cedex 5, 34295, France.

Aims: Transition care programmes are designed to improve coordination of care between hospital and home. For heart failure patients, meta-analyses show a high efficacy but with moderate evidence level. Moreover, difficulties for implementation of such programmes limit their extrapolation.

Methods And Results: We designed a mixed-method study to assess the implementation of the PRADO-IC, a nationwide transition programme that aims to be offered to every patient with heart failure in France. This programme consists essentially in an administrative assistance to schedule follow-up visits and in a nurse follow-up during 2 to 6 months and aims to reduce the annual heart failure readmission rate by 30%. This study assessed three quantitative aims: the cost to avoid a readmission for heart failure within 1 year (primary aim, intended sample size 404 patients), clinical care pathways, and system economic outcomes; and two qualitative aims: perceived problems and benefits of the PRADO-IC. All analyses will be gathered at the end of study for a joint interpretation. Strengths of this study design are the randomized controlled design, the population included in six centres with low motivation bias, the primary efficiency analysis, the secondary efficacy analyses on care pathway and clinical outcomes, and the joint qualitative analysis. Limits are the heterogeneity of centres and of intervention in a control group and parallel development of other new therapeutic interventions in this field.

Conclusions: The results of this study may help decision-makers to support an administratively managed transition programme.

Myocardial Injury After Balloon Predilatation Versus Direct Transcatheter Aortic Valve Replacement: Insights From the DIRECTAVI Trial.

J Am Heart Assoc 2020 12 10;9(24):e018405. Epub 2020 Dec 10.

Department of Cardiology Montpellier University Hospital Montpellier France.

Background Myocardial injury is associated with higher mortality after transcatheter aortic valve replacement (TAVR) and might be increased by prior balloon aortic valvuloplasty (BAV). We aimed to evaluate the impact of prior BAV versus direct prosthesis implantation on myocardial injury occurring after (TAVR) with balloon-expandable prostheses. Methods and Results The DIRECTAVI (Direct Transcatheter Aortic Valve Implantation) trial, an open-label randomized study, demonstrated noninferiority of TAVR without BAV (direct TAVR group) compared with systematic BAV (BAV group) with the Edwards SAPIEN 3 valve. High-sensitivity troponin was assessed before and the day after the procedure. Incidence of myocardial injury after the procedure (high-sensitivity troponin elevation >15× the upper reference limit [14 ng/L]) was the main end point. Impact of myocardial injury on 1-month adverse events (all-cause mortality, stroke, major bleeding, major vascular complications, transfusion, acute kidney injury, heart failure, pacemaker implantation, and aortic regurgitation) was evaluated. Preprocedure and postprocedure high-sensitivity troponin levels were available in 211 patients. The mean age of patients was 83 years (78-87 years), with 129 men (61.1%). Mean postprocedure high-sensitivity troponin was 124.9±81.4 ng/L in the direct TAVR group versus 170.4±127.7 ng/L in the BAV group (=0.007). Myocardial injury occurred in 42 patients (19.9%), including 13 patients (12.2%) in the direct TAVR group and 29 (27.9%) in the BAV group (=0.004). BAV increased by 2.8-fold (95% CI, 1.4-5.8) myocardial injury probability. Myocardial injury was associated with 1-month adverse events (=0.03). Conclusions BAV increased the incidence and magnitude of myocardial injury after TAVR with new-generation balloon-expandable valves. Myocardial injury was associated with 1-month adverse events. These results argue in favor of direct SAPIEN 3 valve implantation. Registration URL: https://www.Clinicaltrials.gov; Unique identifier: NCT02729519.

Acute Coronary Syndrome in the Era of SARS-CoV-2 Infection: A Registry of the French Group of Acute Cardiac Care.

CJC Open 2021 Mar 11;3(3):311-317. Epub 2020 Nov 11.

Univ Paris Est Créteil, INSERM, IMRB, Créteil, France.

Background: In this study, we aimed to report clinical characteristics and outcomes of patients with and without SARS-CoV-2 infection who were referred for acute coronary syndrome (ACS) during the peak of the pandemic in France.

Methods: We included all consecutive patients referred for ST-elevation myocardial infarction (STEMI) or non-STEMI (NSTEMI) during the first 3 weeks of April 2020 in 5 university hospitals (Paris, south, and north of France), all performing primary percutaneous coronary intervention.

Results: The study included 237 patients (67 ± 14 years old; 69% male), 116 (49%) with STEMI and 121 (51%) with NSTEMI. The prevalence of SARS-CoV-2-associated ACS was 11% (n = 26) and 11 patients had severe hypoxemia on presentation (mechanical ventilation or nasal oxygen > 6 L/min). Patients were comparable regarding medical history and risk factors, except a higher prevalence of diabetes mellitus in SARS-CoV-2 patients (53.8% vs 25.6%;  = 0.003). In SARS-CoV-2 patients, cardiac arrest on admission was more frequent (26.9% vs 6.6%; < 0.001). The presence of significant coronary artery disease and culprit artery occlusion in SARS-CoV-2 patients respectively, was 92% and 69.4% for those with STEMI, and 50% and 15.5% for those with NSTEMI. Percutaneous coronary intervention was performed in the same percentage of STEMI (84.6%) and NSTEMI (84.8%) patients, regardless of SARS-CoV-2 infection, but no-reflow (19.2% vs 3.3%; < 0.001) was greater in SARS-CoV-2 patients. In-hospital death occurred in 7 SARS-CoV-2 patients (5 from cardiac cause) and was higher compared with noninfected patients (26.9% vs 6.2%; < 0.001).

Conclusions: In this registry, ACS in SARS-CoV-2 patients presented with high a percentage of cardiac arrest on admission, high incidence of no-reflow, and high in-hospital mortality.

Background: Postinfarction adverse left ventricular (LV) remodelling is strongly associated with heart failure events. Conicity index, sphericity index and LV global functional index (LVGFI) are new LV remodelling indexes assessed by cardiac magnetic resonance (CMR).

Aim: To assess the predictive value of the new indexes for 1-year adverse LV remodelling in patients with anterior ST-segment elevated myocardial infarction (STEMI).

Methods: CMR studies were performed in 129 patients with anterior STEMI (58±12 years; 78% men) from the randomized CIRCUS trial (CMR substudy) treated with primary percutaneous coronary intervention and followed for the occurrence of major adverse cardiovascular events (MACE) (death or hospitalization for heart failure). Conicity index, sphericity index, LVGFI, infarct size and microvascular obstruction (MVO) were assessed by CMR performed 5±4 days after coronary reperfusion. Adverse LV remodelling was defined as an increase in LV end-diastolic volume of ≥15% by transthoracic echocardiography at 1 year.

Results: Adverse LV remodelling occurred in 27% of patients at 1 year. Infarct size and MVO were significantly predictive of adverse LV remodelling: odds ratio [OR] 1.03, 95% confidence interval [CI] 1.01-1.05 (P<0.001) and OR 1.12, 95% CI 1.05-1.22 (P<0.001), respectively. Among the newly tested indexes, only LVGFI was significantly predictive of adverse LV remodelling (OR 1.10, 95% CI 1.03-1.16; P=0.001). In multivariable analysis, infarct size remained an independent predictor of adverse LV remodelling at 1 year (OR 1.05, 95% CI 1.02-1.08; P<0.001). LVGFI and infarct size were associated with occurrence of MACE: OR 1.21, 95% CI 1.08-1.37 (P<0.001) and OR 1.02, 95% CI 1.00-1.04 (P=0.018), respectively. Conicity and sphericity indexes were not associated with MACE.

Conclusions: LVGFI was associated with adverse LV remodelling and MACE 1 year after anterior STEMI.

Reperfusion therapies in pulmonary embolism-state of the art and expert opinion: A position paper from the "Unité de Soins Intensifs de Cardiologie" group of the French Society of Cardiology.

Electronic address:

Acute pulmonary embolism is a frequent cardiovascular emergency with an increasing incidence. The prognosis of patients with high-risk and intermediate-high-risk pulmonary embolism has not improved over the last decade. The current treatment strategies are mainly based on anticoagulation to prevent recurrence and reduce pulmonary vasculature obstruction. However, the slow rate of thrombus lysis under anticoagulation is unable to acutely decrease right ventricle overload and pulmonary vasculature resistance in patients with severe obstruction and right ventricle dysfunction. Therefore, patients with high-risk and intermediate-high-risk pulmonary embolism remain a therapeutic challenge. Reperfusion therapies may be discussed for these patients, and include systemic thrombolysis, catheter-directed therapies and surgical thrombectomy. High-risk patients require systemic thrombolysis, but may have contraindications as a result of the high risk of bleeding. In addition, intermediate-high-risk patients should not receive systemic thrombolysis, despite its high efficacy, because of prohibitive bleeding complications. Recently, percutaneous reperfusion techniques have been developed to acutely decrease pulmonary vascular obstruction with lower-dose or no thrombolytic agents and, thus, potentially higher safety than systemic thrombolysis. Some of these techniques improve key haemodynamic variables. Cardiac surgical techniques and venoarterial extracorporeal membrane oxygenation as temporary circulatory support may be useful in selected cases. The development of pulmonary embolism centres with multidisciplinary pulmonary embolism teams is mandatory to enable adequate use of reperfusion and improve outcomes. We aim to present the state of the art regarding reperfusion therapies in pulmonary embolism, but also to provide guidance on their indications and patient selection.

Time-to-treatment initiation of colchicine and cardiovascular outcomes after myocardial infarction in the Colchicine Cardiovascular Outcomes Trial (COLCOT).

Eur Heart J 2020 11;41(42):4092-4099

Université de Montpellier, INSERM, CNRS, CHU de Montpellier, France.

Aims: The COLchicine Cardiovascular Outcomes Trial (COLCOT) demonstrated the benefits of targeting inflammation after myocardial infarction (MI). We aimed to determine whether time-to-treatment initiation (TTI) influences the beneficial impact of colchicine.

Methods And Results: In COLCOT, patients were randomly assigned to receive colchicine or placebo within 30 days post-MI. Time-to-treatment initiation was defined as the length of time between the index MI and the initiation of study medication. The primary efficacy endpoint was a composite of cardiovascular death, resuscitated cardiac arrest, MI, stroke, or urgent hospitalization for angina requiring coronary revascularization. The relationship between endpoints and various TTI (<3, 4-7 and >8 days) was examined using multivariable Cox regression models. Amongst the 4661 patients included in this analysis, there were 1193, 720, and 2748 patients, respectively, in the three TTI strata. After a median follow-up of 22.7 months, there was a significant reduction in the incidence of the primary endpoint for patients in whom colchicine was initiated < Day 3 compared with placebo [hazard ratios (HR) = 0.52, 95% confidence intervals (CI) 0.32-0.84], in contrast to patients in whom colchicine was initiated between Days 4 and 7 (HR = 0.96, 95% CI 0.53-1.75) or > Day 8 (HR = 0.82, 95% CI 0.61-1.11). The beneficial effects of early initiation of colchicine were also demonstrated for urgent hospitalization for angina requiring revascularization (HR = 0.35), all coronary revascularization (HR = 0.63), and the composite of cardiovascular death, resuscitated cardiac arrest, MI, or stroke (HR = 0.55, all P < 0.05).

Conclusion: Patients benefit from early, in-hospital initiation of colchicine after MI.

Immediate vs Delayed Stenting in ST-Elevation Myocardial Infarction: Rationale and Design of the International PRIMACY Bayesian Randomized Controlled Trial.

Can J Cardiol 2020 Nov 25;36(11):1805-1814. Epub 2020 Jan 25.

Hospital of Annecy, Centre Hospitalier Annecy Genevois, Annecy, France.

Background: Primary percutaneous coronary intervention is used to restore blood flow in the infarct-related coronary artery, followed by immediate stenting to prevent reocclusion. Stents implanted in thrombus-laden arteries cause distal embolization, which paradoxically impairs myocardial reperfusion and ventricular function. Whether a strategy of delayed stenting improves outcomes in patients with acute ST-elevation myocardial infarction (STEMI) is uncertain.

Methods: The Primary Reperfusion Secondary Stenting (PRIMACY) is a Bayesian prospective, randomized, open-label, blinded end point trial in which delayed vs immediate stenting in patients with STEMI were compared for prevention of cardiovascular death, nonfatal myocardial infarction, heart failure, or unplanned target vessel revascularization at 9 months. All participants were immediately reperfused, but those assigned to the delayed arm underwent stenting after an interval of 24 to 48 hours. This interval was bridged with antithrombin therapy to reduce thrombus burden. In the principal Bayesian hierarchical random effects analysis, data from exchangeable trials will be combined into a study prior and updated with PRIMACY into a posterior probability of efficacy.

Results: A total of 305 participants were randomized across 15 centres in France and Canada between April 2014 and September 2017. At baseline, the median age of participants was 59 years, 81% were male, and 3% had a history of percutaneous coronary intervention. Results from PRIMACY will be updated from the patient-level data of 1568 participants enrolled in the Deferred Stent Trial in STEMI (DEFER; United Kingdom), Minimalist Immediate Mechanical Intervention (MIMI; France), Danish Trial in Acute Myocardial Infarction-3 (DANAMI-3; Denmark), and Impact of Immediate Stent Implantation Versus Deferred Stent Implantation on Infarct Size and Microvascular Perfusion in Patients With ST Segment-Elevation Myocardial Infarction (INNOVATION, South Korea) trials.

Conclusions: We expect to clarify whether delayed stenting can safely reduce the occurrence of adverse cardiovascular end points compared with immediate stenting in patients with STEMI.

Kinetic modelling of myocardial necrosis biomarkers offers an easier, reliable and more acceptable assessment of infarct size.

Sci Rep 2020 08 12;10(1):13597. Epub 2020 Aug 12.

Loire Valley Cardiovascular Collaboration, Université de Tours, EA 4245 T2I & FHU SUPORT, Tours, France.

Infarct size is a major prognostic factor in ST-segment elevation myocardial infarction (STEMI). It is often assessed using repeated blood sampling and the estimation of biomarker area under the concentration versus time curve (AUC) in translational research. We aimed at developing limited sampling strategies (LSS) to accurately estimate biomarker AUC using only a limited number of blood samples in STEMI patients. This retrospective study was carried out on pooled data from five clinical trials of STEMI patients (TIMI blood flow 0/1) studies where repeated blood samples were collected within 72 h after admission to assess creatine kinase (CK), cardiac troponin I (cTnI) and muscle-brain CK (CK-MB). Biomarker kinetics was assessed using previously described biomarker kinetic models. A number of LSS models including combinations of 1 to 3 samples were developed to identify sampling times leading to the best estimation of AUC. Patients were randomly assigned to either learning (2/3) or validation (1/3) subsets. Descriptive and predictive performances of LSS models were compared using learning and validation subsets, respectively. An external validation cohort was used to validate the model and its applicability to different cTnI assays, including high-sensitive (hs) cTnI. 132 patients had full CK and cTnI dataset, 49 patients had CK-MB. For each biomarker, 180 LSS models were tested. Best LSS models were obtained for the following sampling times: T4-16 for CK, T8-T20 for cTnI and T8-T16 for CK-MB for 2-sample LSS; and T4-T16-T24 for CK, T4-T12-T20 for cTnI and T8-T16-T20 for CK-MB for 3-sample LSS. External validation was achieved on 103 anterior STEMI patients (TIMI flow 0/1), and the cTnI model applicability to recommended hs cTnI confirmed. Biomarker kinetics can be assessed with a limited number of samples using kinetic modelling. This opens the way for substantial simplification of future cardioprotection studies, more acceptable for the patients.

Letter in reply to the letter to the editor of Geerts N and Schanhorst V with the title "Roche Troponin T hs-STAT meets all expert opinion analytical laboratory practice recommendations for the use of the differential diagnosis of acute coronary syndrome".

Clin Chem Lab Med 2020 Aug 1. Epub 2020 Aug 1.

Department of Biochemistry, University Hospital of Montpellier, Montpellier, France.

Over the period from December 3rd, 2019 to March 13th, 2020, after the urgent field safety notice reported by Roche, we performed double determinations of all troponins from the same tube in parallel and in the same run. We used the same Elecsys troponin T hs reagent (ref 08469873190), first result was obtained with the current hs-cTnT application (18 min) and the second measurement was with the STAT application (9 min). On the 11,388 results in the range from 3 to 500 ng/L, we observed 4.18% discordant results (above 18.8% RCV). Overall, we observed an overestimation of the hs-cTnT STAT assay. The Elecsys Troponin T hs STAT assay demonstrated good analytical performances on Cobas e801 analyzer. However, its use according to the ESC recommendations for the 0 h/1 h algorithm should be carefully evaluated and requires further studies with serial cTn testing.

Colchicine and myocardial infarction: A review.

Arch Cardiovasc Dis 2020 Oct 22;113(10):652-659. Epub 2020 Jul 22.

Department of Cardiology, Montpellier University Hospital, 34295 Montpellier, France; PhyMedExp, University of Montpellier, INSERM U1046, CNRS UMR 9214, 34295 Montpellier, France.

The inflammatory response is frequent after acute myocardial infarction, and may worsen ischaemia-reperfusion injuries, leading to increased infarct size and poor prognosis. Therefore, inflammation may be a promising therapeutic target, and anti-inflammatory drugs appear to be potential additional treatments in this context. Among these treatments, colchicine-a well-known drug that has been used for centuries in clinical practice for rheumatism-may represent the ideal candidate. Indeed, colchicine exerts direct anti-inflammatory and pleiotropic effects, with potential anti-arrhythmic, anti-fibrotic and anti-atherosclerotic effects, which are particularly interesting in this population of patients. The effects of colchicine in the context of acute myocardial infarction were first studied in preclinical models, with a decrease in inflammation demonstrated in several in vitro and in vivo models. Moreover, a decrease in infarct size and positive effects on haemodynamic variables were also recently demonstrated in a mouse model. Regarding clinical studies, the positive effect of colchicine in stable coronary disease and atherosclerosis was assessed initially. More recently, the value of colchicine in acute myocardial infarction has been studied, showing a positive effect on inflammation and infarct size reduction. Finally, a randomised trial (the COLCOT study) has shown a reduction in outcomes in patients with acute coronary syndrome treated with colchicine.

Multimarker approach including CRP, sST2 and GDF-15 for prognostic stratification in stable heart failure.

ESC Heart Fail 2020 10 10;7(5):2230-2239. Epub 2020 Jul 10.

Cardiology Department, University Hospital of Montpellier, Montpellier, France.

Aims: Inflammation and cardiac remodelling are common and synergistic pathways in heart failure (HF). Emerging biomarkers such as soluble suppression of tumorigenicity 2 (sST2) and growth differentiation factor-15 (GDF-15), which are linked to inflammation and fibrosis process, have been proposed as prognosis factors. However, their potential additive values remain poorly investigated.

Methods And Results: Here, we aimed at evaluating inflammatory and remodelling biomarkers to predict both short-term and long-term mortality in a population with chronic HF in comparison with other classical clinical or biological markers (i.e. N terminal pro brain natriuretic peptide, hs-cTnT, C-reactive protein) alone or using meta-analysis global group in chronic HF risk score in a cohort of 182 patients followed during 80 months (interquartile range: 12.3-90.0). Proportional hazard assumption does not hold for sST2 and C-reactive protein, and follow-up was split into short term (less than 1 year), midterm (between 1 and 5 years), and long term (after 5 years). In univariate analysis, C-reactive protein and sST2 were predictive of short-term mortality but not of middle term and long term whereas GDF-15 was predictive of short and mid-term but not of long-term mortality. In a multivariate model after adjustment for meta-analysis global group in chronic HF score including the three markers, only sST2 was predictive of short-term mortality (P = 0.0225), and only GDF-15 was predictive of middle term mortality (P = 0.0375). None of the markers was predictive of long-term mortality.

Conclusions: Our results demonstrate that both sST2 and GDF-15 significantly improve the prognosis evaluation of HF patients and suggest that the value of GDF-15 is more sustained overtime and could predict middle term events.
