E/e′, the ratio of mitral valve flow in early diastole and peak annulus motion velocity; EF, ejection fraction; FS, left ventricular short‐axis shortening; HR, heart rate; IVSd, ventricular septal end‐diastolic thickness; LVDd, left ventricular end‐diastolic diameter; LVDs, left ventricular end‐systolic diameter; LVPWd, left ventricular posterior wall end‐diastolic thickness; MI, myocardial infarction.

Data are presented as mean ± SD.
