Incident Atrial Fibrillation Among Asians, Hispanics, Blacks, and Whites
Atrial Fibrillation Thursday, October 10th, 2013CIRCULATIONAHA: October 8, 2013
Background—As the association between atrial fibrillation (AF) and race has only been rigorously compared in population-based studies that dichotomized participants as White or Black, it is unclear whether White race confers elevated AF risk or Black race affords AF protection.
Methods and Results—The Healthcare Cost and Utilization Project was used to identify patients receiving hospital-based care in California between January 1, 2005 and December 31, 2009. The association between race and incident AF was examined using Cox proportional hazards models. Interaction analyses were performed to elucidate the mechanism underlying the race-AF association. Among 13,967,949 patients, 375,318 incident AF episodes were observed over a median 3.2 (IQR 1.8-4.3) years. Read more
