ABSTRACT
OBJECTIVE:
To investigate the safety and efficacy of percutaneous coronary intervention (PCI) in patients with low left ventricular ejection fraction (LVEF) and complex small coronary artery lesions.METHODS:
Complete or partial post-PCI revascularization of coronary artery was employed in 16 patients with a low LVEF and complex small coronary artery lesions who were unsuitable for CABG (coronary artery bypass grafting). All cases were observed with regards to immediate success rate of operation, complication, hospitalization duration, improvement of cardiac function and LVEF and major adverse cardiac events (including cardiac death, myocardial infarction and target lesion revascularization) at 12 months post-operation.RESULTS:
All cases were successfully treated without death and severe complications while the hospitalization duration was (11 +/- 5) days. The follow-up survey at 12 months post-operation showed that no major adverse cardiac event occurred, the post-operative improvement of cardiac function was from III - IV grade to I - II grade, the improvement of LVEF was from 25% - 45% [(29 +/- 8)%] to 32% - 48% [(37 +/- 7)%], left ventricular end diastolic diameter (LVDd) was shortened from 52 - 79 (66 +/- 11) mm to 49 - 68 (58 +/- 8) mm. The reexamination of 14 cases by coronary angiography at 12 months post-operation showed that there was no intra-stent thrombosis while 20% - 40% intra-stent restenosis occurred in 2 cases.CONCLUSION:
For patients with a low LVEF and complex small coronary artery lesions, PCI is a safe and effective method to lower the mortality rate of CHD patients with heart failure and improve the long-term patient prognosis.
