Abstract

Background: Obesity is a risk factor for cardiovascular disease (CVD) and is also associated with an increased risk of death in subjects without CVD. However, in heart failure (HF), elevated body mass index (BMI) has been shown to be associated with better prognosis, but it is unknown whether this is the case in unselected HF patients encountered in routine clinical practice in Japan. Methods and Results: The Japanese Cardiac Registry of Heart Failure in Cardiology (JCARE-CARD) studied prospectively the characteristics and treatments in a broad sample of patients hospitalized with worsening HF and the outcomes were followed for 2.1 years. Study cohort (n=2,488) was classified into 3 groups according to baseline BMI: <20.3 kg/m2 (n=829), 20.3-23.49 kg/m2 (n=832), and ≥23.5 kg/m2 (n=827). The mean BMI was 22.3±4.1 kg/m2. Patients with higher BMI had lower rates of all-cause death, cardiac death, and rehospitalization because of worsening HF. After multivariable adjustment, the risk for all-cause death and cardiac death significantly increased with decreased BMI levels compared with patients with BMI ≥23.5 kg/m2. However, BMI levels were not associated with rehospitalization for worsening HF. Conclusions: Lower BMI was independently associated with increased long-term all-cause, as well as cardiac, mortality in patients with HF encountered in routine clinical practice in Japan.
