title: Recent mortality of Japanese patients with atrial fibrillation in an urban city of Tokyo.
abstract: BACKGROUND
  In Japan, the recent status of the mortality of atrial fibrillation (AF) patients is still unclear.
  
  
  RESULTS
  We used a single-hospital based cohort database in an urban city (Tokyo) in Japan, including all the new visitors from 2004 to 2009 (n=13,228). The non-adjusted death rates of AF patients for all-cause, stroke, and cardiovascular death were 1091, 97, and 727 per 100,000 patient-years, and the age-adjusted ones were 317 (95% CI, 316-318), 16 (95% CI, 16-16), and 238 (95% CI, 237-239), respectively. The age-adjusted relative risk of AF on all-cause mortality was 1.7 in the particular population.
  
  
  CONCLUSIONS
  The present study provides the most recent data about the characteristics and the mortality of AF patients in Tokyo, thus serving as the basic information for finding problems to solve regarding Japanese AF patients.
