ABSTRACT
BACKGROUND:
High body mass index (BMI) is associated with a higher risk of heart failure (HF) in patients with new-onset type 2 diabetes mellitus (T2DM). However, limited studies have investigated the independent association between fat mass or lean body mass and HF risk among T2DM patients with cardiovascular disease (CVD) or high CVD risk.OBJECTIVES:
To investigate the association between fat mass index (FMI, kg/m2) or lean BMI (LBMI, kg/m2) and HF risk.METHODS:
This was a post hoc analysis of the Action to Control Cardiovascular Risk in Diabetes (ACCORD) study. Cox proportional-hazards models were applied to evaluate the association of FMI, LBMI, and BMI with HF risk. Discordant analysis was performed to compare the magnitude of this associations.RESULTS:
HF occurred in 356 participants (3.7%). After adjusting for confounding factors, higher FMI values were independently associated with HF risk (HR 1.72, 95% CI 1.15-2.57, each 1 SD increase in FMI); LBMI was a protective risk factor for HF (HR 0.58, 95% CI 0.38-0.87,). After further adjusting for FMI, the association between BMI and HF risk (HR, 0.97; 95% CI, 0.67-1.42) disappeared. Compared with concordant values below the medians, discordant FMI above the median with BMI below yielded an HR of 1.78 (95% CI 1.14-2.78) for HF. In contrast, BMI above the median with FMI below was not associated with HF risk (HR 1.09, 95% CI 0.57-2.09).CONCLUSIONS:
The risk of HF conferred by higher BMI was primarily driven by the association between FMI and HF. After adjusting for BMI, LBMI played a protective role.
