Prognostic impact of acute pulmonary triggers in patients with takotsubo syndrome: new insights from the International Takotsubo Registry.

ESC Heart Fail 2021 Jun 13;8(3):1924-1932. Epub 2021 Mar 13.

Department of Cardiology, Charité, Campus Rudolf Virchow, Berlin, Germany.

Aims: Acute pulmonary disorders are known physical triggers of takotsubo syndrome (TTS). This study aimed to investigate prevalence of acute pulmonary triggers in patients with TTS and their impact on outcomes.

Methods And Results: Patients with TTS were enrolled from the International Takotsubo Registry and screened for triggering factors and comorbidities. Patients were categorized into three groups (acute pulmonary trigger, chronic lung disease, and no lung disease) to compare clinical characteristics and outcomes. Of the 1670 included patients with TTS, 123 (7%) were identified with an acute pulmonary trigger, and 194 (12%) had a known history of chronic lung disease. The incidence of cardiogenic shock was highest in patients with an acute pulmonary trigger compared with those with chronic lung disease or without lung disease (17% vs. 10% vs. 9%, P = 0.017). In-hospital mortality was also higher in patients with an acute pulmonary trigger than in the other two groups, although not significantly (5.7% vs. 1.5% vs. 4.2%, P = 0.13). Survival analysis demonstrated that patients with an acute pulmonary trigger had the worst long-term outcome (P = 0.002). The presence of an acute pulmonary trigger was independently associated with worse long-term mortality (hazard ratio 2.12, 95% confidence interval 1.33-3.38; P = 0.002).

Conclusions: The present study demonstrates that TTS is related to acute pulmonary triggers in 7% of all TTS patients, which accounts for 21% of patients with physical triggers. The presence of acute pulmonary trigger is associated with a severe in-hospital course and a worse long-term outcome.

Left ventricular pacing with a temporary pacemaker: Case report.

Rev Port Cardiol (Engl Ed) 2021 Feb 26;40(2):141.e1-141.e4. Epub 2020 Dec 26.

Department of Cardiology, Centro Hospitalar São João, EPE, Porto, Portugal.

We report a case of temporary pacemaker lead malposition in the left ventricle crossing the interventricular septum (IVS). The majority of described cases occur due to a patent foramen ovale and are frequently incidental findings. A course across the IVS is rarely found and this complication with temporary leads is not even reported in the literature. This very rare location entails a risk of dangerous complications associated with left-to-right flow after lead removal. Echocardiography was an essential tool to diagnose the lead's course inside the heart and enabled secure removal of the lead with cardiac surgery backup.

Age-Related Variations in Takotsubo Syndrome.

J Am Coll Cardiol 2020 04;75(16):1869-1877

Krankenhaus "Maria Hilf" Medizinische Klinik, Stadtlohn, Germany.

Background: Takotsubo syndrome (TTS) occurs predominantly in post-menopausal women but is also found in younger patients.

Objectives: This study aimed to investigate age-related differences in TTS.

Methods: Patients diagnosed with TTS and enrolled in the International Takotsubo Registry between January 2011 and February 2017 were included in this analysis and were stratified by age (younger: ≤50 years, middle-age: 51 to 74 years, elderly: ≥75 years). Baseline characteristics, hospital course, as well as short- and long-term mortality were compared among groups.

Results: Of 2,098 TTS patients, 242 (11.5%) patients were ≤50 years of age, 1,194 (56.9%) were 51 to 74 years of age, and 662 (31.6%) were ≥75 years of age. Younger patients were more often men (12.4% vs. 10.9% vs. 6.3%; p = 0.002) and had an increased prevalence of acute neurological (16.3% vs. 8.4% vs. 8.8%; p = 0.001) or psychiatric disorders (14.1% vs. 10.3% vs. 5.6%; p < 0.001) compared with middle-aged and elderly TTS patients. Furthermore, younger patients had more often cardiogenic shock (15.3% vs. 9.1% vs. 8.1%; p = 0.004) and had a numerically higher in-hospital mortality (6.6% vs. 3.6% vs. 5.1%; p = 0.07). At multivariable analysis, younger (odds ratio: 1.60; 95% confidence interval: 0.86 to 3.01; p = 0.14) and older age (odds ratio: 1.09; 95% confidence interval: 0.66 to 1.80; p = 0.75) were not independently associated with in-hospital mortality using the middle-aged group as a reference. There were no differences in 60-day mortality rates among groups.

Conclusions: A substantial proportion of TTS patients are younger than 50 years of age. TTS is associated with severe complications requiring intensive care, particularly in younger patients.

Myocardial dysfunction in Takotsubo syndrome: More than meets the eye?

Rev Port Cardiol (Engl Ed) 2019 Apr 16;38(4):261-266. Epub 2019 May 16.

Serviço de Cardiologia, Centro Hospitalar Universitário de São João, E.P.E., Porto, Portugal.

Introduction: Takotsubo syndrome (TTS) is characterized by transient left ventricular (LV) dysfunction, typically mimicking an anterior wall myocardial infarction (MI), without obstructive coronary artery disease. In the few published reports assessing myocardial deformation in TTS and MI, no consistent differences have been described between the two entities. We sought to characterize global and regional function in TTS and to compare it with a population with MI.

Methods: Clinical data, including echocardiography, were gathered from 17 TTS patients and 20 anterior wall ST-segment elevation myocardial infarction (STEMI) controls. Peak systolic longitudinal strain was determined for each LV segment using speckle tracking imaging, and global and mean apical, midventricular and basal longitudinal strain were calculated from these.

Results: Both TTS and STEMI patients presented significant LV systolic dysfunction, and there were no significant differences in ejection fraction or global longitudinal strain. Regional longitudinal strain was more severely impaired in basal inferolateral and mid anterolateral segments in the TTS group and in apical anteroseptal segments in the STEMI group. Mean longitudinal strain was worse in the basal segments of TTS patients (-9.8±2.9 vs. -12.4±4.1%, p=0.010), with no significant differences in mid and apical segments. The basal/apical ratio was significantly lower in this group as well (1.51±0.86 vs. 2.94±1.88, p=0.006).

Conclusions: While both TTS and STEMI feature significantly impaired global systolic function, we found a regional pattern of worse basal longitudinal strain and a lower basal/apical ratio in the former. These suggest generalized myocardial impairment in TTS, providing new clues about its pathophysiology and possible specific echocardiographic changes.

Percutaneous Closure of a Fistulous Giant Coronary Aneurysm.

Can J Cardiol 2018 06 3;34(6):812.e13-812.e15. Epub 2018 Feb 3.

Cardiology Department, Centro Hospitalar São João, Porto, Portugal; Faculty of Medicine, Porto University, Porto, Portugal.

Giant coronary artery aneurysms larger than 50 mm are rare and associated with important complications: namely, rupture. Its workup requires comprehensive imaging and standard treatment is surgical exclusion. We present a 60-year-old patient with previous ostium secundum atrial septal defect surgical closure diagnosed with a giant proximal right coronary artery aneurysm (70 x 62 mm) fistulizing into the right atrium. Percutaneous closure of its aortic origin with an atrial septal occluder was successfully performed, and thrombosis of the aneurysm confirmed on angiography and echocardiogram. This case depicts an innovative, minimally invasive approach to this worrisome entity.

Maternal educational level and the risk of persistent post-partum glucose metabolism disorders in women with gestational diabetes mellitus.

Acta Diabetol 2018 Mar 29;55(3):243-251. Epub 2017 Dec 29.

Unit of Population Epidemiology, Department of Community Medicine, Primary Care, and Emergency Medicine, Geneva University Hospitals, Rue Gabrielle Perret-Gentil, 1205, Geneva, Switzerland.

Aims: Gestational diabetes mellitus (GDM) occurs in 5-15% of pregnancies, and lower maternal educational attainment has been associated with higher risk of GDM. We aimed to determine if maternal education level is associated with persistent post-partum glucose metabolism disorders in women with GDM.

Methods: Retrospective cohort study of women with GDM followed in 25 Portuguese health institutions between 2008 and 2012. Educational attainment was categorised into four levels. Prevalence of post-partum glucose metabolism disorders (type 2 diabetes mellitus, increased fasting plasma glucose or impaired glucose tolerance) was compared and adjusted odds ratios calculated controlling for confounders using logistic regression.

Results: We included 4490 women diagnosed with GDM. Educational level ranged as follows: 6.8% (n = 307) were at level 1 (≤ 6th grade), 34.6% (n = 1554) at level 2 (6-9th grade), 30.4% (n = 1364) at level 3 (10-12th grade) and 28.2% (n = 1265) at level 4 (≥ university degree). At 6 weeks post-partum re-evaluation, 10.9% (n = 491) had persistent glucose metabolism disorders. Educational levels 1 and 2 had a higher probability of persistent post-partum glucose metabolism disorders when compared to level 4 (OR = 2.37 [1.69;3.32], p < 0.001 and OR = 1.39 [1.09;1.76], p = 0.008, for level 1 and 2, respectively), an association that persisted in multivariable logistic regression adjusting for confounders (level 1 OR = 2.25 [1.53;3.33], p < 0.001; level 2 OR = 1.43 [1.09;1.89], p = 0.01).

Conclusions: Persistent post-partum glucose metabolism disorders are frequent in women with GDM and associated with lower maternal educational level. Interventions aimed at this risk group may contribute towards a decrease in prevalence of post-partum glucose metabolism disorders.
