Tuesday, October 02, 2012 Reduction in Diabetes Prevalence Could Mean Decreases in HF Hospitalizations At the population level, diabetes is a stronger risk factor for new heart failure (HF) than 4 other modifiable risk factors, namely smoking, dyslipidemia, obesity, and hypertension, suggests the latest analysis from the Atherosclerosis Risk in Communities (ARIC) study cohort. ARIC is a longitudinal study of more than 15,000 African American and Caucasian men and women in 4 communities across the United States, who were recruited during the 1980s when they were aged 45 to 64. The current analysis included 14,709 of the participants followed an average of 17.6 years. According to the authors, the lifetime risk of incident heart failure was about 1 in 3 for its African American participants and reached 1 in 4 in Caucasians. In both groups, that risk was higher than the lifetime risk of new coronary heart disease or stroke in the same population. In addition, they found that a percentage drop in diabetes prevalence would avert more cases of new HF than the same percentage decrease of any of the 4 other studied modifiable risk factors. Specifically, a 5% proportional reduction in the prevalence of diabetes in ARIC African American participants would result in approximately 53 fewer HF cases per 100,000 person-years and 33 fewer HF hospitalizations per 100,000 person-years for Caucasians.
