ABSTRACT

Objective To investigate the clinical efficacy of drug-eluting stent( DES) combined with clopi-dogrel therapy in patients with coronary heart disease. Methods 123 patients underwent percutaneous coronary intervention (PCI) were randomly divided into observation group (DES) of 60 cases and the control group ( bare-metal stent,BMS) of 63 cases. The observation group was given the treatment of DES combined clopidogrel, the control group was given the treatment of BMS combined clopidogrel. The stent implantation and the follow-up two-year MACE were observed. Results (1) The average implanted stent length of the observation group was longer than that of the control group(P<(0.05) ,the angiography in vascular disease and complexity between the two groups had no significant difference ( P > 0. 05 ) ; the success rate of surgery in the two groups was 100% , after operation the TIMI flow reached grade 3. (2) The incidence of angina pectoris and revascularization rate of the observation group was significantly lower than that of the control group (P < 0.05); the rate of coronary angiography, recurrent myocardial infarction and the incidence of cardiac death between the two groups had no significant difference ( P > 0.05). Conclusion DES combined with clopidogrel maintenance therapy for a year in patients with coronary heart disease had a good long-term efficacy.
