Randomized Controlled Trial Comparative StudyLong-term outcome after drug-eluting versus bare-metal stent implantation in patients with ST-segment elevation myocardial infarction: 5 years follow-up from the randomized DEDICATION trial (Drug Elution and Distal Protection in Acute Myocardial Infarction).
This study sought to compare the long-term effects of drug-eluting stent (DES) compared with bare-metal stent (BMS) implantation in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention. ⋯ The 5-year MACE rate was insignificantly different, but the cardiac mortality was higher after DES versus BMS implantation in patients with STEMI. Stent thrombosis was the main cause of late cardiac deaths.

Impact of public reporting and outlier status identification on percutaneous coronary intervention case selection in Massachusetts.
This study sought to evaluate the impact of public reporting of hospitals as negative outliers on percutaneous coronary intervention (PCI) case-mix selection. ⋯ The risk profile of PCI patients at outlier institutions was significantly lower after public identification compared with nonoutlier institutions, suggesting that risk-aversive behaviors among PCI operators at outlier institutions may be an unintended consequence of public reporting in Massachusetts.

Multicenter StudyRenal function-based contrast dosing predicts acute kidney injury following transcatheter aortic valve implantation.
This study sought to assess whether the volume of contrast media (CM) influences the occurrence of acute kidney injury (AKI) following transcatheter aortic valve implantation (TAVI). ⋯ Although mechanisms of AKI following TAVI are multifactorial, the present study identified a relationship between CM dose increment and high prevalence of AKI. Therapeutic efforts not to exceed the threshold value may reduce the risk of AKI.
