Multicenter StudySurvival after shock therapy in implantable cardioverter-defibrillator and cardiac resynchronization therapy-defibrillator recipients according to rhythm shocked. The ALTITUDE survival by rhythm study.
This study sought to determine if the risk of mortality associated with inappropriate implantable cardioverter-defibrillator (ICD) shocks is due to the underlying arrhythmia or the shock itself. ⋯ Compared with no shock, those who received their first shock for ventricular rhythms and atrial fibrillation had an increased risk of death. There was no significant difference in survival after inappropriate shocks for sinus tachycardia or noise/artifact/oversensing. In this study, the adverse prognosis after first shock appears to be more related to the underlying arrhythmia than to an adverse effect from the shock itself.

Long-term cardiovascular risk in women prescribed fertility therapy.
The purpose of the study was to investigate whether fertility therapy might contribute to subsequent cardiovascular disease. ⋯ Successful fertility therapy was not associated with an increased risk of cardiovascular disease later in life.

Significance of non-type 1 anterior early repolarization in patients with inferolateral early repolarization syndrome.
The aim of this study was to investigate the significance of non-type 1 anterior early repolarization (NT1-AER) combined with inferolateral early repolarization syndrome (ERS). ⋯ Inferolateral ERS comprises heterogeneous ER subtypes with and without NT1-AER. Coexistence of NT1-AER was a key predictor of poor outcome in patients with ERS.
