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.
ABSTRACT
Objective The study aimed to analyze the clinical features and the causes of hospital death among the 5720 acute myocardial infarction(AMI)patients from Cardiology Center,Beijing Chao-Yang Hospital during the last 8 years. Methods A total of 5720 AMI patients received treatment in the Cardiology Center from January 1st ,2002 to December 31th ,2009 were retrospectively reviewed. All patients were classified according to age into 3 groups of ≤45,46 -75,and ＞ 75 years old. The morbidity,cause of death ,whether they had the PCI therapy,mortality after PCI and the impact of gender on the cause of death were observed respectively. Results The morbidity rate of male was significantly higher than female in all three groups,and the study also found that the morbidity rate of female was significantly higher in the group of ＞ 75 years old,which however was still lower than that of male. The AMI patients were more likely to accept PCI therapy,which could significantly reduce the mortality rate. The top 3 causes of death included acute heart failure(AHF),cardiogenic shock(CGS)and AHF combined with CGS. In addition,AHF caused significantly more death in female and older(＞ 75 years old)patients. Conclusions The morbidity rate of AMI patients in Beijing Chao-Yang Hospital increased year by year. And PCI therapy could reduce the mortality rate of all groups. Revascularization treatment seems to be feasible and safe for the patients older than 75 years old.
