Abstract Background This study evaluates cardiac diseases and prognosis in young adults and adults presenting with ventricular tachyarrhythmias (VTA). Methods The present longitudinal, observational, registry-based, monocentric cohort study includes all consecutive patients 45 years old or younger presenting with VTA at admission from 2002 to 2016. Rates of coronary angiography, coronary artery disease (CAD) and need for percutaneous coronary intervention (PCI), cardiac diseases associated with VTA, and differences in long-term prognostic endpoints for young adults (20–34 years old) were analyzed and compared to those of adults (35–45 years old), for whom multivariable risk prediction models were developed. Kaplan–Meier analyses were performed according to age and type of VTA. Results A total of 259 consecutive patients were included in the study (36% young adults and 64% adults). At admission, 38% of young adults had VTA due to CAD that required PCI. Furthermore, VTA in young adults was commonly idiopathic (27%), or had underlying channelopathies (18%), primary cardiomyopathies (13%) or acute myocardial infarction (AMI, 11%). In adults, VTA was mostly associated with AMI (28%), though the rate of idiopathy was still high (20%). A total 41% of all patients received cardiopulmonary resuscitation (CPR), for whom AMI (STEMI 17%, NSTEMI 24%) was most frequently observed. Irrespective of the type of VTA, all-cause mortality was similar for young adults and adults. In young adults, left ventricular ejection fraction (LVEF)

Abstract Objectives The study sought to assess the impact of statin therapy on survival in patients presenting with ventricular tachyarrhythmias. Background Data regarding the outcome of patients with statin therapy presenting with ventricular tachyarrhythmias is limited. Methods A large retrospective registry was used including all consecutive patients presenting with ventricular tachycardia (VT) or fibrillation (VF) from 2002 to 2016. Patients with statin were compared to patients without statin therapy (non-statin). The primary prognostic endpoint was long-term all-cause death at 3 years. Uni- and multivariable Cox regression analyses were applied in propensity-score matched cohorts. Results A total of 424 matched patients was included. The rates of VT and VF were similar in both groups (VT: statin 71% vs. non-statin 68%; VF: statin 29% vs. 32%; p = 0.460). Statin therapy was associated with lower all-cause mortality at long-term follow-up (mortality rates 16% versus 33%; log rank, p = 0.001; HR = 0.438; 95% CI 0.290–0.663; p = 0.001), irrespective of the underlying type of ventricular tachyarrhythmia (VT/VF), left ventricular ejection fraction (LVEF) > 35%, presence of an activated implantable cardioverter defibrillator (ICD), cardiogenic shock or cardiopulmonary resuscitation (CPR). Conclusion Statin therapy is independently associated with lower long-term mortality in patients presenting with ventricular tachyarrhythmias on admission.

Abstract Objectives The study sought to assess the prognostic impact of type 2 diabetes in patients presenting with ventricular tachyarrhythmias on admission. Background Data regarding the prognostic outcome of diabetics presenting with ventricular tachyarrhythmias is limited. Methods A large retrospective registry was used including all consecutive patients presenting with ventricular tachycardia (VT) and fibrillation (VF) on admission from 2002 to 2016. Patients with type 2 diabetes (diabetics) were compared to non-diabetics applying multivariable Cox regression models and propensity-score matching for evaluation of the primary prognostic endpoint of long-term all-cause mortality at 2 years. Secondary prognostic endpoints were cardiac death at 24 h, in-hospital death at index, all-cause mortality at 30 days, all-cause mortality in patients surviving index hospitalization at 2 years (i.e. “after discharge”) and rehospitalization due to recurrent ventricular tachyarrhythmias at 2 years. Results In 2411 unmatched high-risk patients with ventricular tachyarrhythmias, diabetes was present in 25% compared to non-diabetics (75%). Rates of VT (57% vs. 56%) and VF (43% vs. 44%) were comparable in both groups. Multivariable Cox regression models revealed diabetics associated with the primary endpoint of long-term all-cause mortality at 2 years (HR = 1.513; p = 0.001), which was still proven after propensity score matching (46% vs. 33%, log rank p = 0.001; HR = 1.525; p = 0.001). The rates of secondary endpoints were higher for in-hospital death at index, all-cause mortality at 30 days, as well as after discharge, but not for cardiac death at 24 h or rehospitalization due to recurrent ventricular tachyarrhythmias. Conclusion Presence of type 2 diabetes is independently associated with an increase of all-cause mortality in patients presenting with ventricular tachyarrhythmias on admission.
