- W4362737662 abstract "Current guidelines for aortic regurgitation (AR) recommend the same linear left ventricular (LV) dimension for intervention regardless of age and sex. The purpose of this study was to evaluate the impact of age and sex on the degree of LV remodeling and outcomes. We included consecutive patients with severe AR who were serially monitored by echocardiogram between 2010 and 2016. The 2 main endpoints were as follows: 1) LV end-systolic volume indexed to body surface area (LVESVi) and LV end-diastolic volume indexed to body surface area; and 2) adverse events (AE). We evaluated the longitudinal rate of LV remodeling and determined the association between LV volume and AE by age and sex. A total of 525 adult patients (26% women) with a median echocardiogram follow-up of 2.0 years (IQR: 1.0-3.6 years) were included. At baseline, older patients (age ≥60 years) had smaller LV volumes compared with younger patients (age <60 years), eg, the mean LVESVi was 27.3 mL/m2 vs 32.3 mL/m2, respectively. Similarly, women had smaller LV volumes compared with men (mean LVESVi was 23.3 mL/m2 vs 32.4 mL/m2). On serial evaluation, older patients and women maintained smaller LV volumes compared with younger patients and men, respectively. There were 210 (40%) AE during follow-up. The optimal discriminatory threshold for AE varies by age and sex, eg, the LVESVi threshold was highest for young men (50 mL/m2), intermediate for older men (35 mL/m2), and lowest for women (27 mL/m2). On serial evaluation, older patients and women with chronic AR maintained smaller LV volumes than younger patients and men, respectively, and develop AE at lower LV volumes." @default.
