The influence of complete revascularization by PCI on heart function of heart dysfunction patients with multivessel coronary artery disease / 中国实用内科杂志

ABSTRACT

Objective To evaluate the influence of complete or incomplete revascularization by percutaneous coronary intervention(PCI)on heart function of heart dysfunction patients with multivessel coronary artery disease.Methods The study retrospectively analysed the clinical data and the echocardiogram result in patients with multivessel coronary artery diease complicated with heart dysfunction,who underwent PCI procedure from October 1994 to October 2004 in our center.Results 6 months after revascularization by PCI,DE,SV,CO,LVEF,FS,MVCF and E/A elevated,MVEF velocity increased,and EPSS decreased in both complete and incomplete revascularization groups,but the above heart function indexes tested by echocardiogram in complete revascularization patients were better than those of incomplete revascularization patients.Conclusion PCI can significantly improve the heart function in both groups,but complete revascularization by PCI improves the heart function of patient with multivessel coronary artery disease more obviously in compare with incomplete revascularization.
