Description
Summary:To determine whether there is seasonal variation in hospitalisations and deaths due to atrial fibrillation (AF) and to examine possible contributors to such variability. We used the linked Scottish Morbidity Record scheme, which provides individualised morbidity and mortality data for the entire Scottish population. Between 1990 and 1996, there were a total of 33,582 male and 34,463 female hospitalisations related to AF. Significantly more admissions occurred in winter compared to summer ( P85 years—peak winter rates being 35–39% higher than average. A similar phenomenon was evident in relation to mortality in these patients. The average number of men who died during December was 22% higher, and in August 12% lower, than average, P
