  1. ANCOVA was used to compare among all groups after adjustment for baseline differences. Asym, asymptomatic symptom status; LV- EDVi, left ventricular end-diastolic volume, indexed to body surface area; Sym, symptomatic symptoms status. Symptom status is shown at baseline and at follow-up (baseline/follow-up).
