LAAD: left atrium anteroposterior diameter; LVEDD: left ventricular end-diastolic dimension; RVAD: right ventricular anteroposterior diameter; LVEDV: left ventricular end-diastolic volume; AVPG: aortic valve peak gradien; AVMG: aortic valve mean gradient; LVEF: left ventricular ejection fraction; Vmax: peak aortic velocity; PASP: pulmonary artery systolic pressure; AR: aortic regurgitation; TR: tricuspid regurgitation. Moderate-severe valve regurgitation includes moderate valve regurgitation and severe valve regurgitation. ^aCompared with HFpEF group, p < 0.05. ^bCompared with HFmrEF group, p < 0.05. ^∆ Fisher’s exact tests
