Abstract

Introduction

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.

Objective

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.

Method

The study included 1954 patients who were followed up for 4 years in military hospitals of Algeria. Obesity was classified as a body mass index > 30 and overweight as a body mass index of 25.0–29.9. Central obesity was defined as waist circumference > 88 cm for women and > 102 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 38% of patients, overweight in 46%, and central obesity in 63%. 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.

Conclusion

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.
