Long-term outcomes stratified by body mass index in patients undergoing transcatheter aortic valve implantation
The American Journal of Cardiology Oct 16, 2020
Quine EJ, Dagan M, William J, et al. - Given that for older patients suffering from severe, symptomatic, and trileaflet aortic stenosis, transcatheter aortic valve implantation (TAVI) is emerging as the default strategy, and that raised BMI is related to a protective impact in patients receiving percutaneous coronary intervention, therefore, researchers investigated if high BMI was related to a similar link in TAVI. They assessed prospectively obtained data from 634 patients who received TAVI at 2 centers from August 2008 to April 2019. The participants were grouped as normal weight, overweight, and obese. Increasing age, male gender, COPD, previous balloon valvuloplasty, and higher STS-PROM were identified as variables independently related to increased mortality. Findings showed that lower long-term mortality was experienced by overweight patients vs normal weight and obese patients receiving TAVI.
