Aim To determine the prevalence, clinical characteristics, in-hospital course and determinants of major adverse events in a cohort of Caucasian patients with Takotsubo syndrome (TTS) and right ventricular involvement (RVi), regardless of left ventricular variant forms. Methods and results The study population consisted of 424 patients (mean age 69.1 ± 11.5 years; female 92.2%) with a diagnosis of TTS divided into two groups according to the presence or absence of RVi. RVi patients (n = 57; 13.4%) showed a higher prevalence of comorbidities, especially respiratory diseases (p = 0.011), and a higher Charlson comorbidity index (CCI; p = 0.006) than non-RVi patients. In-hospital major adverse events (acute heart failure, cardiogenic shock and death) occurred more frequently in RVi patients (p < 0.001). Heart rate and CCI, along with the echocardiographic parameters of wall motion score index, E/e’ ratio, tricuspid annular plane systolic excursion (TAPSE) and systolic pulmonary artery pressure (sPAP) were associated with adverse in-hospital outcome. At multivariate analysis, CCI (HR: 1.871; 95% CI: 1.202–2.912; p = 0.006), sPAP (HR: 1.059; 95% CI: 1.016–1.104; p = 0.007) and TAPSE (HR: 0.728; 95% CI: 0.619–0.855; p < 0.001) were independent correlates of the composite outcome in patients with RVi. Conclusion Patients with RVi are characterized by distinct clinical profile and should undergo closely clinical and echocardiographic monitoring. The presence of echocardiographic signs of right ventricular failure along with substantial comorbidities burden identify a cohort at higher risk of in-hospital major adverse cardiovascular events.
