Do alternative left atrial volume indexation methods predict all-cause mortality better than standard body surface area indexation in individuals with overweight or obesity?
The study evaluates the prognostic value of 9 different left atrial volume indexation methods for predicting all-cause mortality in overweight or obese individuals.
BACKGROUND: Alternative indexation methods for left atrial volume (LAV) have been proposed to achieve better proportional scaling than the current standard body surface area indexation. However, there are limited data showing that these alternative indices provide long-term prognostic value in individuals with overweight or obesity. The aim of this study was to determine and compare the performance of various LAV indexation methods in predicting all-cause mortality in individuals with overweight or obesity. METHODS: and valid LAV, height, weight, and left ventricular ejection fraction. We conducted receiver operating characteristic analyses, including area under the curve calculations, to compare the performance of 9 LAV indices in predicting all-cause mortality. In addition, we performed a survival analysis between LAV and all-cause mortality. RESULTS: , with no difference by sex. CONCLUSIONS: .

Madronio et al. (Thu,) conducted a observational in Overweight or obesity. Left atrial volume (LAV) indexation methods vs. Standard body surface area indexation was evaluated on All-cause mortality. The performance of various left atrial volume indexation methods in predicting all-cause mortality in individuals with overweight or obesity showed no difference by sex.
