Six-Year Changes in Physical Activity and the Risk of Incident Heart Failure: ARIC Study.

ABSTRACT:

Background

Higher physical activity (PA) is associated with lower heart failure (HF) risk; however, the effect of changes in PA on HF risk is unknown.

Methods

We evaluated 11 351 ARIC study (Atherosclerosis Risk in Communities) participants (mean age 60 years) who attended visit 3 (1993-1995) and did not have a history of cardiovascular disease. Exercise PA was assessed using a modified Baecke questionnaire and categorized according to American Heart Association guidelines as recommended, intermediate, or poor. We used Cox regression models to characterize the association of 6-year changes in PA between the first (1987-1989) and third ARIC visits and HF risk.

Results

During a median of 19 years of follow-up, 1750 HF events occurred. Compared with those with poor activ
