ABSTRACT
Objective To investigate the efficacy and security of cypher stent(sirolimus-eluting stent)in the treatment of old patients with coronary heart disease(CHD).Methods From November 2002 to May 2005,328 elderly CHD cases(age:60-86 years)were treated with 415 Cypher stents.Among the 328 patients,66 had ST-segment elevation of myocardial infarction,21 had non ST-segment elevation of myocardial infarction,149 had unstable angina and 92 had stable angina.As for lesion characteristics,diffuse disease was found in 91 case(26.1%),bifurcation lesions in 68 cases(19.6%),chronic total occlusion lesions in 56 cases(16.0%),in-stent restenosis in 14 cases and ostial lesions in 15 case.The immediate angiographic outcome,major cardiac event(MACE) and angiographic follow-up at 6 months were assessed.Results Stent implantation was successfully achieved in 99% patients with CHD.Acute and sub-acute stent thrombosis occurred in 2 patients,late stent thrombosis with AMI occurred in 2 patients,1 died during the 6 months follow-up.The MACE rate during hospitalization was 0.6% and 3.6% during 6 months follow-up.Angiographic follow-up in 84 patients at 6 months showed that in-stent restenosis rate(ISR)was 8.3%(restenosis within the stents was 2.4%).The target vessel revascularization(TLR)rate was 5.9%.Conclusions Cypher stent implantation in CHD is safe and effective,the ISR rate and TLR rate are significantly lower than those of bare metal stents.
