Prevention and treatment of coronary heart disease: who benefits?

abstract：BACKGROUND:Atrial fibrillation (AF) is the most common sustained arrhythmia; however, little is known about patients in a primary care setting from high-, middle-, and low-income countries. METHODS AND RESULTS:This prospective registry enrolled patients presenting to an emergency department with AF at 164 sites in 46 ...
