Data are expressed as the means ± standard deviations; *p < 0.05 vs. the sham-operated group; †p < 0.05 vs. the control group;E: mitral early diastolic filling velocity; E’: mitral early diastolic annular velocity; LVEDV: left ventricular end-diastolic volume; LVESV: left ventricular end-systolic volume; LVSV: left ventricular stroke volume; EF: ejection fraction; HR: heart rate; LVEDP: left ventricular end-diastolic pressure; LVSP: left ventricular systolic pressure.
