Abstract:
Objective Using STI and WMSI to evaluate the change of the heart sarcomere local systolic function which suffered from coronary heart disease (CHD), to evaluate the improvement of ischemic heart sarcomere local systolic function after PCI. Methods There are 40 CHD patients after PCI called the treatment group and 40 healthy persons called the control group. Echocardiogram was used to evaluate the change of ventricular wall motion score in the treatment group which was before and 1 week after PCI , compared with the control group. STI is used to get the SLs, GSL and SrLe of the left ventricle six walls in basal segment,middle segmentand apical segment systole. Results The ventricular wall motion index of the left ventricular myocardium obviously rose in CHD patients which was after PCI, compared with the control group (P < 0.05). And it obviously reduced in CHD patients after PCI, compared with CHD patients before PCI(P < 0.05). The results of SLs,GSL and SrLe are reduced in myocardial ischemia segment of CHD patients before PCI,compared with the control group (P < 0.05). But they are significantly improved in the the treatment group 1 week after PCI, compared to which is before PCI(P < 0.05). Conclusion STI and WMS can be used to evaluate the abnormal of regional and global function of myocardium which is caused to coronary artery stenosis the effect of PCI. The left ventricular motion function of CHD is decreased, but the left ventricle regional systolic function of hypokinetic segments in patients with CHD after PCI is significantly increased.
