Clinical analysis of recent prognosis of elderly inpatients at different ages with acute myocardial infarction / 中华老年医学杂志

ABSTRACT

Objective To investigate the influence of age on recent prognosis of elderly inpatients with acute myocardial infarction (AMI).Methods A total of 2535 inpatients with AMI were divided into different age groups.The influences of age and coexistent diseases on prognosis in AMI patients were analyzed retrospectively.Results The hospital mortality and 30-day mortality were higher in patients aged ≥80 years compared with patients aged 65-79 years and patients aged 60-64 years(χ2 =46.378,P<0.01 ;χ2 = 44.534, P<0.01).In 60-64 years old patients with AMI, the prevalences of old myocardial infarction (OMI), renal insufficiency, respiratory insufficiency were higher and the prevalence of angina pectoris was lower in death group than in survival group (all P<0.05).In 65-79 years old patients with AMI, the prevalences of OMI, hypertension, diabetes,cerebrovascular disease, renal insufficiency, respiratory insufficiency were higher and the prevalence of angina pectoris was lower in death group than in survival group(P<0.05).In 80-94 years old patients with AMI, the prevalences of OMI, diabetes, cerebrovascular disease, renal insufficiency, respiratory insufficiency were higher and the prevalence of angina pectoris was lower in death group than in survival group(P<0.05).The prevalences of OMI, hypertension, diabetes, cerebrovascular disease,respiratory insufficiency were significantly increased in 80-94 years old death group versus 60-64 and 65-79 years old death group(all P<0.05).Conclusions The mortality rate of elderly patients with AMI is increased with age and atypical angina pectoris should be paid more attention in these patients.
