Introduction and objectives
To analyze the association between higher body mass index and waist circumference, and the prognostic values of both indicators in total and cardiac mortality in patients with chronic heart failure.Methods
The study included 2254 patients who were followed up for 4 years. Obesity was classified as a body mass index 鈮?0 and overweight as a body mass index of 25.0-29.9. Central obesity was defined as waist circumference 鈮?8 cm for women and 鈮?02 cm for men. Independent predictors of total and cardiac mortality were assessed in a multivariate Cox model adjusted for confounding variables.
Results
Obesity was present in 35% of patients, overweight in 43%, and central obesity in 60%. Body mass index and waist circumference were independent predictors of lower total mortality: hazard ratio =0.84 (P<.001) and hazard ratio = 0.97 (P=.01), respectively, and lower cardiac death (body mass index, hazard ratio =0.84, P<.001; waist circumference, hazard ratio =0.97, P=.01). The interaction between body mass index and waist circumference (hazard ratio =1.001, P<.01) showed that the protective effect of body mass index was lost in patients with a waist circumference >120 cm.
Conclusions
Mortality was significantly lower in patients with a high body mass index and waist circumference. The results also showed that this protection was lost when these indicators over a certain limit.
