Note: Values expressed as mean ± standard deviation and number (percentage). The low-LAV/BSA group includes individuals with LAV/BSA less than the median value; the high-LAV/BSA group includes individuals with LAV/BSA equal to the median value or greater. Tests of significance are t test and χ2.
Abbreviations and definitions: A wave, late filling velocity; E wave, early filling velocity; EDV/BSA, end-diastolic volume corrected for body surface area; ESV/BSA, end-systolic volume corrected for body surface area; LVMi, left ventricular mass index; LVSD, left ventricular systolic dysfunction.
