Values are mean ± SD or n (%), unless otherwise indicated. The p value denotes significant differences among the 4 groups (ANOVA or Kruskal-Wallis test).

ANOVA = analysis of variance; CMR = cardiac magnetic resonance; EF = ejection fraction; ESV = end-systolic volume; MR = mitral regurgitation; NYHA = New York Heart Association.
