Coronary stenting of unprotected left main diseases in elderly patients unsuitable for coronary surgery

Objective:Coronary artery bypass grafting(CABG)is considered the standard treatment for unprotected left main coronary stenosis,few studies have reported on clinical outcomes in elderly patients undergoing percutaneous coronary intervention(PCI).We sought to assess clinical outcomes of elderly patients(age≥75years) undergoing PCI for unprotected left main stenosis not suitable for bypass surgery.Methods: ALL patients with unprotected left main stenosis were treated with stent implantation were consecutively enrolled.Primary outcome was the composite of death,myocardial infarction(MI),or target lession revascularization(TLR).Results: The study included 115 consecutive patients who were treated with drug-eluting stents.Mean age was(78.3±2.6)years,and mean Syntax score and EuroSCORE were(29.3±6.1)And(7.8±4.2),respectively.The overall mortality at the end follow up was 9.5%,the rates of major adverse cardiacdeath,nonfatal acute MI and target lesion revascularization were 7%,6.1%,6.1%,respectively.MACCE is 16.5%.Male and renal insufficiency was significantly related with all cause mortality.Conclusion: PCI treatment is feasible in elderly patients with unprotected left main stenosis who were not suitable for CABG.Male and renal insufficiency was predictors of poor prognosis.
