Intergroup comparisons in left ventricle echocardiographic variables (mean ± standard deviation).

Note: LVEDV: left ventricular end-diastolic volume; LVESV: left ventricular end-diastolic volume; LVEF: left ventricular ejection fraction; LVAV: left ventricular aneurysm volume.Intergroup comparisons in left ventricle echocardiographic variables (mean ± standard deviation).注：左心室舒张末期容积（left ventricular end-diastolic volume, LVEDV）；左心室舒张末期容积（left ventricular end-diastolic volume, LVESV）；左心室射血分数（left ventricular ejection fraction, LVEF）；左心室室壁瘤容积（left ventricular aneurysm volume, LVAV）。左心室超声心动图参数的组间比较（均值±标准差）。
