Randomized Controlled Trial Multicenter StudyImpact of nonculprit vessel myocardial perfusion on outcomes of patients undergoing percutaneous coronary intervention for acute coronary syndromes: analysis from the ACUITY trial (Acute Catheterization and Urgent Intervention Triage Strategy).
This study evaluated the impact of nonculprit vessel myocardial perfusion on outcomes of non-ST-segment elevation acute coronary syndromes (NSTE-ACS) patients. ⋯ Reduced myocardial perfusion in an area supplied by a nonculprit vessel is associated with increased short- and long-term mortality rates in NSTE-ACS patients undergoing PCI. Furthermore, worst nonculprit MBG is able to risk-stratify patients with normal baseline flow of the culprit vessel.

Randomized Controlled Trial Multicenter Study Comparative StudyUtilization of radial artery access for percutaneous coronary intervention for ST-segment elevation myocardial infarction in New York.
This study sought to determine the utilization and outcomes for radial access for percutaneous coronary intervention (PCI) for ST-segment elevation acute myocardial infarction (STEMI) in common practice. ⋯ The use of a radial access site for PCI in STEMI patients increased between 2009 and 2010, but was still infrequent in 2010, and was used for lower-risk STEMI patients. There was no significant difference in mortality by access site, but there was a trend toward a mortality advantage for patients with a radial access site among hospitals that used it relatively frequently.

ReviewPercutaneous left atrial appendage occlusion for stroke prophylaxis in nonvalvular atrial fibrillation: a systematic review and analysis of observational studies.
The goal of this study was to provide a systematic review and analysis of observational studies on percutaneous left atrial appendage (LAA) occlusion for stroke prophylaxis in nonvalvular atrial fibrillation (NVAF). ⋯ Our systematic review suggested comparable efficacy of LAA occlusion devices compared with historical controls treated with adjusted-dose warfarin and other anticoagulation strategies for prevention of stroke in patients with NVAF.
