ABSTRACT

ObjectiveTo explore the in-hospital mortality and its determinants for very eldly (80 + years of age) patients with acute myocardial infarction (AMI).MethodsA retrospective cohort method was used.The 499 study subjects were very eldly patients with newly diagnosed AMI consecutively admitted into our department between January 1,2002 and February 22,2010.ResultsNinety-seven out of 499 patients died during hospitalization period,with total in-hospital mortality of 19.4％.Multivariable logistic regression analysis showed the independent determinants for mortality of very elderly AMI patients were cardiac Killip grades,complete A-V block,renal dysfunction,stent implant,and the type of AMI.Conclusions The independent determinants for mortality of elderly AMI patients are as following,cardiac Killip grade,complete A-V block,renal dysfunction,stent implant,and the type of MAI.Urgent PCI is safe and effective for some very elderly with AMI,which could improve their survival rate within hospitalization period.
