Abstract
Objective:To investigate clinical features in elderly patients with acute myocardial infarction.Methods:A total of 86 patients older than 80 years with acute myocardial infarction were selected as the elderly group and 132 cases with 60-80 years of age as the control group.Clinical date including general condition,area of infarction,complication and mortality were retrospectively analyzed and compared.Results:The rate of revascularization was significantly lower in elderly group(P0.01),while the incidence of complication and mortality were significantly higher in elderly group(P0.01 or 0.05).The disease of descending anterior branch accounted for 62.8% in elderly group and 47.0% in control group,with significant difference between two groups(P0.05).A total of 66.7% in elderly group and 33.3% in control group died of complication,with significant difference between two groups(P0.05).Conclusions:The criminal vessel in elderly patients with acute myocardial infarction mainly consists of descending anterior branch.The mortality is high and associated with complication.
