The aim of the present study was to determine whether body mass index (BMI) influences survival and recurrent cardiovascular events in a cardiac rehabilitation population. We followed 389 consecutive entrants to cardiac rehabilitation for 6.4 ± 1.8 years. Patients were stratified into 3 groups: normal (BMI 18 to 24.9 kg/m2), overweight (BMI 25 to 29.9 kg/m2), and obese (BMI ≥30 kg/m2). Total and cardiovascular mortality were inversely associated with BMI category in bivariate models. However, only cardiovascular mortality was significant after adjustment for age and gender (p <0.044), with cardiovascular death rates of 10% in normal, 8% in overweight, and 2% in obese patients. The rates of nonfatal recurrent events were 10% in normal, 24% in overweight, and 25% in obese patients. Our data indicate that BMI is inversely related to cardiovascular mortality but positively related to the risk of nonfatal recurrent events.
