Background: This study aims to validate the Academic Research Consortium for High Bleeding Risk (ARC-HBR) criteria in Chinese patients with atrial fibrillation (AF) and acute coronary syndrome (ACS) or undergoing percutaneous coronary intervention (PCI) who received both oral anticoagulants (OAC) and antiplatelet therapy (APT).

Methods: 930 consecutive patients with AF and ACS or undergoing PCI receiving both OAC and APT were recruited and followed up for 1 year. The primary endpoint was BARC type 3 or 5 bleeding. The secondary endpoints included BARC type 2, 3, or 5 bleeding, TIMI major bleeding, TIMI major or minor bleeding, and major adverse cardiovascular events (a composite of all-cause death, stroke, non-central nervous system embolism, myocardial infarction, definite or probable stent thrombosis, and target vessel revascularization). Cox regressions were performed to evaluate the association between the ARC-HBR score and outcomes. Discrimination was evaluated through analysis of the receiver operating characteristic (ROC) curves, net reclassification improvement (NRI), and integrated discrimination improvement (IDI).

Results: Compared to patients with no HBR other than OAC, patients with HBR besides OAC tended to have more comorbidities and worse outcomes. The ARC-HBR score was significantly associated with the primary and secondary endpoints, both as a continuous variable and as a categorical variable. The ARC-HBR score performed better than the HAS-BLED score (c-statistic: 0.692 vs. 0.575, NRI = 0.313, IDI = 0.061) and the PRECISE-DAPT score (c-statistic: 0.692 vs. 0.616, NRI = 0.393, IDI = 0.049).

Conclusions: In patients with AF and ACS or undergoing PCI receiving both OAC and APT, the ARC-HBR score was a significant predictor of 1-year bleeding and ischemic endpoints. The ARC-HBR score performed better than the HAS-BLED score and the PRECISE-DAPT score in BARC type 3 or 5 bleeding prediction.

Utility of a pharmacogenetic-driven algorithm in guiding dual antiplatelet therapy for patients undergoing coronary drug-eluting stent implantation in China.

Eur J Clin Pharmacol 2022 Feb 12;78(2):215-225. Epub 2021 Oct 12.

Emergency and Critical Care Center, State Key Laboratory of Cardiovascular Disease, National Center for Cardiovascular Diseases, Fuwai Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, No. 167 Beilishi Road, Xicheng District, Beijing, People's Republic of China.

Purposes: The POPular Risk Score (PRiS), a pharmacogenetic-driven algorithm consisting of CYP2C19 genotype, platelet reactivity, and clinical risk factors, is developed to evaluate ischemic risk and guide dual antiplatelet therapy (DAPT). This study aimed to evaluate the efficacy and safety of DAPT in accordance with the PRiS in patients undergoing drug-eluting stent (DES) implantation.

Methods: A total of 1757 patients recruited in this cohort study were divided into four groups according to the PRiS and type of P2Y12 receptor inhibitor treatment at discharge. The primary endpoint was major adverse cardiovascular events (MACE, a composite of cardiovascular death, myocardial infarction, stroke, definite or probable stent thrombosis, and target vessel revascularization) during 1-year follow-up. The safety endpoints were defined by Bleeding Academic Research Consortium (BARC) criteria as major bleeding (BARC 3a, 3b, 3c, and 5) and clinically relevant bleeding (BARC 2, 3a, 3b, 3c, and 5).

Results: Among 1046 patients with PRiS < 2 and 711 patients with PRiS ≥ 2, 34.2% and 38.3% of them were treated with ticagrelor, respectively. The PRiS ≥ 2 was an independent predictor for the 1-year incidence of MACE (HR(95%CI): 2.09 (1.37-3.20), p = 0.001). Multivariable Cox regression indicated that in the PRiS ≥ 2 group, ticagrelor was superior to clopidogrel in reducing the risk of MACE (HR(95%CI): 0.53 (0.29-0.98), p = 0.042), without increasing the bleeding risk. On the other hand, in the PRiS < 2 group, clopidogrel treatment was related to a remarkably lower rate of BARC class ≥ 2 bleeding (HR(95%CI): 0.39 (0.20-0.72), p = 0.003), but comparable incidences of MACE and BARC class ≥ 3 bleeding during 1-year follow-up. Similar associations between P2Y12 receptor inhibitors and 1-year endpoints in the PRiS < 2 and PRiS ≥ 2 group could also be identified in propensity score-weighted analysis and propensity score-matched analysis.

Conclusion: Tailored DAPT based on the PRiS could assist in improving the prognosis of patients undergoing DES implantation. Further randomized controlled trials are required to provide more evidence for PRiS-guided DAPT.

Performance of the REACH, PARIS, BleeMACS, and PRECISE-DAPT scores for predicting 1-year bleeding events in patients undergoing coronary drug-eluting stent implantation.

Platelets 2021 Oct 11:1-8. Epub 2021 Oct 11.

Emergency and Critical Care Centre, State Key Laboratory of Cardiovascular Disease, Fuwai Hospital, National Centre for Cardiovascular Diseases, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, People's Republic of China.

This study aimed to evaluate the predictive performance of the REACH, PARIS, BleeMACS, and PRECISE-DAPT scores in Chinese patients undergoing coronary drug-eluting stent (DES) implantation. A total of 1911 patients undergoing coronary DES implantation were consecutively recruited and followed up for 1 year. The primary endpoints were BARC type 3 or 5 bleeding and BARC type 2,3, or 5 bleeding. The BleeMACS score and the PRECISE-DAPT score were significantly associated with 1-year incidence of BARC type 3 or 5 bleeding, but not BARC type 2, 3, or 5 bleeding. The discrimination of the PRECISE-DAPT score was moderate for BARC type 3 or 5 bleeding (c-statistic = 0.633), while those of the REACH (c-statistic = 0.533), PARIS (c-statistic = 0.553), and BleeMACS scores (c-statistic = 0.613) were relatively low. However, the analysis of c-statistic, NRI, and IDI detected no significant discrimination improvement of the PRECISE-DAPT score for BARC type 3 or 5 bleeding compared to the other three scores. The calibrations of the PRECISE-DAPT and BleeMACS scores were modest (Hosmer-Lemeshow test > .05). Decision curve analysis indicated net benefit of the PRECISE-DAPT score in bleeding risk evaluation. In conclusion, the PRECISE-DAPT score performed moderately in predicting BARC type 3 or 5 bleeding, while the discriminative capacities of the REACH, PARIS, BleeMACS scores were relatively low in patients undergoing DES implantation. But no significant discrimination improvement of the PRECISE-DAPT score compared to the other scores could be detected. Further studies are required to develop standardized bleeding risk scores for this population.

Effects of angiotensin-converting enzyme inhibitor and angiotensin II receptor blocker on one-year outcomes of patients with atrial fibrillation: insights from a multicenter registry study in China.

J Geriatr Cardiol 2020 Dec;17(12):750-758

Emergency and Critical Care Center, State Key Laboratory of Cardiovascular Disease, Fuwai Hospital, National Center for Cardiovascular Diseases, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.

Objective: To evaluate the effect of angiotensin-converting enzyme inhibitor (ACEI)/angiotensin II receptor blocker (ARB) therapy on the prognosis of patients with atrial fibrillation (AF).

Methods: A total of 1, 991 AF patients from the AF registry were divided into two groups according to whether they were treated with ACEI/ARB at recruitment. Baseline characteristics were carefully collected and analyzed. Logistic regression was utilized to identify the predictors of ACEI/ARB therapy. The primary endpoint was all-cause mortality, while the secondary endpoints included cardiovascular mortality, stroke and major adverse events (MAEs) during the one-year follow-up period. Univariable and multivariable Cox regression were performed to identify the association between ACEI/ARB therapy and the one-year outcomes.

Results: In total, 759 AF patients (38.1%) were treated with ACEI/ARB. Compared with AF patients without ACEI/ARB therapy, patients treated with ACEI/ARB tended to be older and had a higher rate of permanent AF, hypertension, diabetes mellitus, heart failure (HF), left ventricular ejection fraction (LVEF) < 40%, coronary artery disease (CAD), prior myocardial infarction (MI), left ventricular hypertrophy, tobacco use and concomitant medications (all < 0.05). Hypertension, HF, LVEF < 40%, CAD, prior MI and tobacco use were determined to be predictors of ACEI/ARB treatment. Multivariable analysis showed that ACEI/ARB therapy was associated with a significantly lower risk of one-year all-cause mortality [hazard ratio (HR) (95% CI): 0.682 (0.527-0.882), = 0.003], cardiovascular mortality [HR (95% CI): 0.713 (0.514-0.988), = 0.042] and MAEs [HR (95% CI): 0.698 (0.568-0.859), = 0.001]. The association between ACEI/ARB therapy and reduced mortality was consistent in the subgroup analysis.

Conclusions: In patients with AF, ACEI/ARB was related to significantly reduced one-year all-cause mortality, cardiovascular mortality and MAEs despite the high burden of cardiovascular comorbidities.

Association between body mass index and mortality in atrial fibrillation patients with and without diabetes mellitus: Insights from a multicenter registry study in China.

Nutr Metab Cardiovasc Dis 2020 11 28;30(12):2242-2251. Epub 2020 Jul 28.

Emergency and Critical Care Center, State Key Laboratory of Cardiovascular Disease, Fuwai Hospital, National Center for Cardiovascular Diseases, Chinese Academy of Medical Sciences and Peking Union Medical College, No. 167 Beilishi Road, Xicheng District, Beijing, People's Republic of China.

Background And Aims: The aim of this study was to evaluate the association between body mass index (BMI) and mortality in atrial fibrillation (AF) patients with and without diabetes mellitus (DM).

Methods And Results: A total of 1991 AF patients were enrolled and divided into two groups according to whether they have DM at recruitment. Baseline information was collected and a mean follow-up of 1 year was carried out. The primary outcome was defined as all-cause mortality with the secondary outcomes including cardiovascular mortality, stroke and major adverse events (MAEs). Univariable and multivariable Cox regression were performed to estimate the association between BMI and 1-year outcomes in AF patients with and without DM. 309 patients with AF (15.5%) had comorbid DM at baseline. Patients with DM were more likely to have cardiovascular comorbidities, receive relevant medications but carry worse 1-year outcomes. Multivariable Cox regressions indicated that elevated BMI was related with reduced risk of all-cause mortality, cardiovascular mortality and major adverse events. Compared to normal weight, overweight [HR (95% CI): 0.548 (0.405-0.741), p < 0.001] and obesity [HR (95% CI): 0.541 (0.326-0.898), p = 0.018] were significantly related with decreased all-cause mortality for the entire cohort. Remarkably reduced all-cause mortality in the overweight [HR (95% CI): 0.497 (0.347-0.711), p < 0.001] and obesity groups [HR (95% CI): 0.405 (0.205-0.800), p = 0.009] could also be detected in AF patients without DM, but not in those with DM.

Conclusion: Elevated BMI was associated with reduced mortality in patients with AF. This association was modified by DM. The obesity paradox confined to AF patients without DM, but could not be generalized to those with DM.

The efficacy and safety of CYP2C19 genotype-guided antiplatelet therapy compared with conventional antiplatelet therapy in patients with acute coronary syndrome or undergoing percutaneous coronary intervention: A meta-analysis of randomized controlled trials.

Platelets 2020 Nov 16;31(8):971-980. Epub 2020 Jun 16.

Cytochrome P450 (CYP) 2C19 genotype is closely associated with the metabolism and efficacy of clopidogrel, thereby having an important impact on clinical outcomes of patients with acute coronary syndrome (ACS) or undergoing percutaneous coronary intervention (PCI). This study aimed to evaluate the efficacy and safety of CYP2C19 genotype-guided antiplatelet therapy in patients with ACS or undergoing PCI. PubMed, EMBASE, the Cochrane Library and clinicaltrials.gov were searched to identify randomized controlled trials (RCTs) comparing CYP2C19 genotype-guided antiplatelet therapy with conventional therapy in patients with ACS or undergoing PCI. Eight RCTs involving 6708 patients were included in this meta-analysis. CYP2C19 genotype-guided antiplatelet therapy was slightly superior to the conventional antiplatelet therapy in reducing the risk of MACE [RR(95%CI): 0.71(0.51-0.98), = .04]. Meanwhile, the genotype-guided therapy group had significantly lower incidence of myocardial infarction [RR(95%CI): 0.56(0.40-0.78), < .01], but similar risk of all-cause mortality, cardiovascular mortality, stent thrombosis, urgent revascularization and stroke compared to the conventional therapy group. Incidences of major/minor bleeding and major bleeding were comparable between the two groups. In patients with ACS or undergoing PCI, CYP2C19 genotype-guided antiplatelet therapy displayed benefit over conventional antiplatelet therapy in reducing the risk of MACE and myocardial infarction, without increasing bleeding risk. Further RCTs are needed to provide more evidences for CYP2C19 genotype-guided antiplatelet therapy.

Gender-specific association between body mass index and all-cause mortality in patients with atrial fibrillation.

Clin Cardiol 2020 Jul 30;43(7):706-714. Epub 2020 Apr 30.

Emergency and Critical Care Center, State Key Laboratory of Cardiovascular Disease, Fuwai Hospital, National Center for Cardiovascular Diseases, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, People's Republic of China.

Background: Elevated body mass index (BMI) is related with reduced mortality in various cardiovascular diseases.

Hypothesis: Gender-specific association between BMI and mortality exists in atrial fibrillation (AF).

Methods: In this multicenter observational study with a mean follow-up of 1 year, a total of 1991 AF patients were enrolled and divided into two groups based on the gender. The primary endpoint was all-cause mortality while the secondary endpoints were defined as cardiovascular mortality, stroke, and major adverse events during 1-year follow-up. Cox regression was performed to identify the association between BMI and clinical outcomes according to gender.

Results: Female patients with AF tended to be older (P = .027) and thinner (P < .001) than male patients with AF. They were more likely to have heart failure, hyperthyroidism, and valvular AF (all P < .05), but less likely to have coronary artery disease and prior myocardial infarction (all P < .01). Multivariate analysis revealed that overweight (HR(95%CI): 0.55(0.41-0.75), P < .001) and obese patients (HR(95%CI): 0.56(0.34-0.94), P = .028) were associated with significant lower all-cause mortality compared with normal weight patients for the entire cohort. Similar association between elevated BMI and reduced all-cause mortality were only identified in female patients with AF (overweight vs normal weight: HR(95%CI): 0.43(0.27-0.70); obesity vs normal weight: HR(95%CI): 0.46(0.22-0.97)), but not in male patients with AF.

Conclusion: This study indicates that overweight and obesity were related with improved survival in patients with AF. The association between elevated BMI and reduced mortality was dependent on gender, which was only significant in female patients, rather than male patients.
