Background-Uncertainty remains over optimal antithrombotic treatment of patients with atrial fibrillation presenting with myocardial infarction and/or undergoing percutaneous coronary intervention. We investigated the risk and time frame for bleeding following myocardial infarction/percutaneous coronary intervention in patients with atrial fibrillation according to antithrombotic treatment. Methods and Results-Patients

Background-Despite wide dissemination, use of automated external defibrillators (AEDs) in community settings is limited.We assessed how AED accessibility affected coverage of cardiac arrests in public locations. Methods and Results-We identified cardiac arrests in public locations (1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)
