LVEDD: left ventricular end-diastolic dimension; LVEF: left ventricular ejection fraction. △LVEF is obtained by subtracting preoperative parameter from postoperative parameter. ^cCompared with preoperative echocardiogram parameters, p < 0.01. ^aCompared with HFpEF group, p < 0.05. ^dComparison of △LVEF among three groups, p < 0.01
