Abstract:
Objective To evaluate the influence of successful revascularization by percutaneous coronary intervention(PCI)on heart function of patients with heart dysfunction combined with chronic total occlusion(CTO).Methods The clinical data of 272 patients with heart dysfunction combined with CTO were analyzed.The patients were divided into PCI success group(246 cases)and PCI failure group(26 cases)respectively according to the results of PCI.Six months after PCI,the patients underwent cardiac ultrasound examination to compare the heart function between the two groups.Results Cardiac ultrasound examination was successfully performed in 229 patients in PCI success group and 24 patients in PCI failure group at 6 months after PCI.The left ventricular ejection fraction(LVEF)and left ventricular end-diastolic volume index(LVEDVI)showed no significant difference in PCI failure group at 6 months after PCI compared with that before PCI(P＞0.05).In PCI success group,LVEF and LVEDVI were significantly increased at 6 months after PCI compared with that before PCI and compared with that in PCI failure group at 6 months after PCI[(51±5)％ vs.(43±6)％ and(45±2)％,(77±13)ml/m2 vs.(86±12)ml/m2 and(86±10)ml/m2,P＜0.05].The cardiac functional grading in PCI failure group had no significant difference compared with that before PCI(P＞0.05),but in PCI success group it had significant difference compared with that before PCI and compared with that in PCI failure group at 6 months after PCI(P＜0.05).Conclusion Successful revascularization by PCI can improve heart function in patients with heart dysfunction combined with CTO.
