Abstract

Some studies have reported that body-mass index (BMI) and proteinuria are risk factors for heart failure (HF). However, the combined effect of BMI and proteinuria on HF is still unclear. We aimed to investigate the association of BMI and proteinuria levels with the risk of HF in a large community-based population. A total of 61, 113 individuals aged ≥18 years from the prospective Kailuan cohort (recruited during 2006-2007) without preexisting heart failure were included. Each participant was categorized into 4 groups according to BMI (< 25 kg/m2 or ≥ 25 kg/m2) and the urine dipstick test results (negative or positive). The primary outcome was HF. We performed multivariable Cox regression analyses to identify the association between BMI and proteinuria category and incident HF. Over a mean follow-up of 9.97±0.75 years, a total of 987 individuals developed incident HF, 1.62 per 1000 person-years. Compared to BMI < 25 kg/m2 and absence of proteinuria, the risk of HF was higher for BMI ≥ 25 kg/m2 and positive proteinuria (HR 2.630, 95% CI 1.982-3.490, P < 0.0001) (P for trend < 0.0001). Degree of proteinuria in participants was associated with a significantly higher rate of incident HF in dose dependent manner. Compared to consistently negative proteinuria, the risk of HF increased by 75.0% (HR 1.750, 95% CI 1.368-2.239, P < 0.0001) and 127.0% (HR 2.270, 95% CI 1.540-3.347, P < 0.0001) in the proteinuria aggravated group and persistent positive group, respectively. Proteinuria combined with a high BMI level is associated with an increased risk for HF in the Chinese population. However, the mechanism is unknown and awaits further study.
