LA measurements were indexed by height or body surface area (BSA).
.
The HRs ranged from 1.19 (95% CI 1.02, 1.39) for LAD/BSA adjusted for the calculated FRS to 1.34 (95% CI 1.12, 1.60) for LAD/height adjusted for FRS covariates.

Conclusion LA size measurements independently predict clinical outcomes. However, it only improves discrimination over clinical parameters modestly without altering risk classification. Indexing LA size by height is at least as robust as by BSA
