Acute kidney injury (AKI) is associated with death, end-stage renal disease, and heart failure in patients with coronary heart disease. This study investigated the association between AKI and long-term risk of stroke. ⋯ The long-term risk of stroke is weakly associated with AKI after primary isolated CABG, but this association is attenuated and not significant when considering death as a competing risk.

Inappropriate shocks resulting from atrial tachyarrhythmias are highly problematic for patients with an implantable cardioverter defibrillator (ICD). We aimed to determine the effectiveness of catheter ablation of atrial fibrillation (AF) in preventing inappropriate shocks due to rapid AF in patients diagnosed with Brugada syndrome (BS) who were implanted with an ICD. ⋯ AF ablation in BS patients may be reasonable to prevent inappropriate ICD shocks resulting from rapid AF. However, ventricular extrastimuli just after the ablation had better be avoided in them.

Left circumflex artery-related myocardial infarction: does ST elevation matter? Results from the Euro Heart Survey PCI registry.
Little is known about angiographic and clinical differences in patients presenting with left circumflex artery (LCX)-related ST elevation myocardial infarction (STEMI) and non ST elevation myocardial infarction (NSTEMI). We sought to determine the clinical significance of ST elevations in patients with LCX-related myocardial infarction. ⋯ Over 50% of the patients with LCX-related myocardial infarction treated with PCI had ST elevations in the initial electrocardiogram. STEMIs were more often associated with total vessel occlusions or haemodynamic instability. In-hospital mortality was significantly higher in patients with LCX-related STEMI.
