Title: Evaluation of Left Ventricular Systolic Synchrony and Its Systolic Function in Patients with Myocardial Infarction using Single Beat Real-time Four Dimensional Echocardiography
Abstract: Objective To evaluate the left ventricular systolic synchrony and systolic function,and investigate the relation between left ventricular systolic synchrony and its systolic function in the patients with myocardial infarction using single beat real-time four dimensional echocardiography(sRT-4DE).Methods Forty patients with myocardial infarction including 15 cases of old anterior myocardial infarction and 30 healthy adults were conducted sRT-4DE.The full-volume imaging was performed and the data was analyzed by left ventricular analysis(LVA)software.A series of global and regional left ventricular volume curves were plotted.The parameters of left ventricular systolic function and synchrony in global and regional cardiac ventricle were obtained.Results In the myocardial infarction group,the ESV and EDV were larger and the LVEF was lower than those of the control group(P 0.01).The systolic synchrony parameters were significantly greater in the myocardial infarction(P 0.001).The correlation coefficient of SDI and LVEF was r =-0.521,P 0.01.Compared with the control group,the Dispes16 and ESSI increased(P 0.05)in the myocardial infarction group.Conclusion sRT-4DE could evaluate the left ventricular systolic synchrony and systolic function in patients with myocardial infarction accurately.The left ventricular systolic dysfunction could affect the synchrony of left ventricular regional wall motion.
