Abstract Objective: Using echocardiography to evaluate the cardiac function and synchrony in patients with acute myocardial infarction before and after phase Ⅱ cardiac rehabilitation. Methods: Twenty patients with acute myocardial infarction (AMI) after phase Ⅱ cardiac rehabilitation were enrolled in the study. The time difference before ejection of aorta and pulmonary artery, also known as inter ventricular mechanical delay (IVMD), was calculated by pulse Doppler combined with electrocardiogram. The tricuspid annular plane systolic excursion (TAPSE) was calculated using Mmode echocardiography. Realtime threedimensional echocardiography was performed to obtain fullvolume images of apical 4 chambers. Heart rate (HR), left ventricular ejection fraction (LVEF), left ventricular end diastolic volume (LVEDV), left atrial maximal volume (LAVmax), left atrial ejection fraction (LAEF) were analyzed with Qlab 9.0 software, respectively. The time of left ventricle and left atrium to minimal systolic volume (Tmsv) of 16 segments and the maximal difference of corresponding segments (Tmsv16Dif) were also obtained by Qlab 9.0 software. The above parameters as percentage of the cardiac cycle with different heart rates between patients were also calculated from the Qlab 9.0 software, which were LVTmsv16Dif/RR(%) and LATmsv16Dif/RR(%). Results: The HR and LATmsv16Dif/RR(%) in the postrehabilitation were significantly lower than those in the prerehabilitation (P<0.001 and P<0.05). The LVEF and LAEF were significantly higher than those in the prerehabilitation (P<0.001 and P<0.05). There was no significant differences in IVMD, TAPSE, LVEDV, LAVmax and LVTmsv16-Dif/RR(%) between before and after cardiac rehabilitation (P>0.05). Conclusion: Left heart systolic function and left atrial synchrony were improved in patients with acute myocardial infarction after phase Ⅱ cardiac rehabilitation.
