Results are presented as mean±SD. LV indicates left ventricular; LVEDV, left ventricular end-diastolic volume; MWT, mean wall thickness; RV, right ventricular; RVEDV, right ventricular end-diastolic volume; and SV, stroke volume.
P value from repeated measures analysis time effect from baseline to 12 months.
Statistically significant difference compared with baseline from mixed model repeated measures analysis.
