Key result
LAVImin outperforms indexed maximal LA volume in predicting cardiovascular outcomes in HFpEF.

Does LAVImin better predict cardiovascular outcomes than indexed maximal LA volume in patients with HFpEF?
In patients with HFpEF, minimal left atrial volume index (LAVImin) is a stronger predictor of cardiovascular outcomes than maximal LA volume index.

LAVImin may refine HFpEF risk stratification; leaves open whether it should replace maximal volume in practice or guidelines.
<0.05). Conclusions In patients with HF with preserved ejection fraction, LAVImin was more predictive of cardiovascular outcome than indexed maximal LA volume, suggesting this measure may be more physiologically relevant and might better identify patients at high risk for cardiovascular events. LA functional parameters provide prognostic information independent of LAVImin. Registration URL: https://www.clinicaltrials.gov; Unique identifier: NCT00094302.

Shin et al. (2021) conducted an observational in Heart failure with preserved ejection fraction. Minimal left atrial volume (LAVImin) vs. Indexed maximal LA volume was evaluated on Cardiovascular outcome (p=<0.05). Minimal left atrial volume (LAVImin) was more predictive of cardiovascular outcomes than indexed maximal LA volume in patients with heart failure with preserved ejection fraction (p<0.05).
