Recent studies in acute coronary syndrome (ACS) have reported mixed results for trends in ACS subtypes. The All New Zealand Acute Coronary Syndrome Quality Improvement (ANZACS-QI) 31 study evaluated trends in ACS event rates, invasive management and mortality of ST-elevation myocardial infarction (STEMI), non-STEMI (NSTEMI) and unstable angina (UA) in New Zealand. ⋯ We observed declines in the event rates of all ACS subtypes and increases in revascularisation rates. The finding that mortality declined in patients with NSTEMI, but not in patients with STEMI and UA, despite increases in invasive procedures, requires further investigation.

Implantable cardioverter defibrillators can treat life-threatening arrhythmias, but may negatively influence the last phase of life if not deactivated. Advance care planning conversations can prepare patients for future decision-making about implantable cardioverter defibrillator deactivation. This study aimed at gaining insight in the experiences of patients with advance care planning conversations about implantable cardioverter defibrillator deactivation. ⋯ Although patients expressed a need for more information, advance care planning conversations about implantable cardioverter defibrillator deactivation seemed to be uncommon. Deactivation should be more frequently addressed by healthcare professionals, tailored to the disease stage of the patient and readiness to discuss this topic.

Multicenter Study Comparative Study
Mid-regional proatrial natriuretic peptide for predicting prognosis in hypertrophic cardiomyopathy.
N-terminal probrain natriuretic peptide (NT-proBNP) predicts mortality and the development of heart failure in hypertrophic cardiomyopathy (HCM). Mid-regional proatrial natriuretic peptide (MR-proANP) is a stable by-product of production of atrial natriuretic peptide. We sought to compare the prognostic value of MR-proANP and NT-proBNP in HCM. ⋯ MR-proANP emerges as a valuable biomarker for the prediction of death and heart failure related events in patients with HCM.

Limited data are currently available regarding the long-term prognosis of patients with J-wave syndrome (JWS). The aim of this study was to investigate the long-term prognosis of patients with JWS and identify predictors of the recurrence of ventricular fibrillation (VF). ⋯ This multicentre long-term study showed that the presence of global J waves was associated with a higher incidence of VF recurrence in patients with JWS.
