Abstract:
Objective To determine clinical characteristics and the effects of drug-eluting stents on the occurrence of major adverse cardiac events during percuteneous coronary artery interventional(PCI)and long- term outcomes in patients with chronic renal insufficiency(CRI).Methods Nine hundreds and seventy three patients with angiographically-documented coronary artery disease(lumen inner diameter narrowing＞50%), included 516 patients complicated with experienced renal impairment(CRI group)and 457 with normal renal function(control group).Baseline clinical data and coronary angiographic features were recorded.Results Comparing with control group,patients in CRI group were older with higher incidence of hypertension or diabetes and simultaneously complicated by reduced left ventricular ejection fraction,and more complex coronary lesions(type C).During follow-up(mean 17 months),the mortality was significantly higher in CRI than in control group(6.2% vs 3.3%,P＜0.05),but the former with CRI was significantly lower by using drug-eluting stents in comparing with bare-metal stents(4.1% vs 8.5%,P＜0.05).Conclusion Patients with CRI often complicated with severe coronary artery disease,the mortality after PCI would be significantly reduced by using drug-eluting stents.
