Effect of Elevated Body Mass Index on Outcomes of Transcatheter Aortic Valve Replacement for Severe Aortic Stenosis.

ABSTRACT:

Background

The association of body mass index (BMI) and an "obesity paradox" with cardiovascular risk prediction is controversial. This study aimed to evaluate the impact of elevated BMI on the outcome of transcatheter aortic valve replacement (TAVR) for aortic stenosis.

Methods

This retrospective study included 1019 patients with a BMI of ≥18.5 kg/m2 divided into 3 groups: 1) normal BMI (18.5-24.9 kg/m2), 2) overweight (25-29.9 kg/m2), and 3) obese (≥30 kg/m2). Propensity score matching was used to compare normal BMI with overweight and normal BMI with obese.

Results

The median age of the cohort was 82 years, and 348 patients had a normal BMI, while 319 and 352 patients were overweight and obese, respectively. After 1 : 1 propensity score matching, 258 and 192 pairs
