RESUMEN
Objective To analyze clinical characteristics, hospital treatment, complications and mortality differences of the patients with acute myocardial infarction (AMI) by conventional treatment. Methods Retrospective analysis of 426 cases of AMI patients, aged 20-103 years [mean age(67. 82 ±0. 56) years] ,male 261 cases,female 165 cases, the general condition of patients were recorded, history features, diagnosis, treatment, complications and prognosis. Comparison of elderly(≥70 years) and non-elderly(＜70 years) ,male and female patients with clinical features, treatment, complications and mortality differences. Results Compared with the non-elderly patients with AMI,elderly patients had significantly lower smoking history(P＜0.05) ,female ratio,history of old myocardial infarction rate, cardiac function≥Killip Ⅲ level was significantly higher(all P＜0.05). During hospitalization in patients of different ages diuretics,β blockers, digitalis, clopidogrel and other drugs, application of a significant difference (all P＜0.05). Elderly AMI patients with complete left bundle branch block,atrioventricular block,atrial fibrillation,the incidence was higher than non-elderly patients (all P＜0.05) ,but no difference in mortality between the two groups (P＞0.05). Female patients than male patients with age of onset was significantly (P＜0.05) , and the smoking rate is low,but clearly the high rate of angina died(P＜0.05) ,sub-poor cardiac function after myocardial infarction(P＜0.05). Application of cardiac drugs in addition to nutrition than men,female patients, the rate of other conventional therapy,no difference in both complications and prognosis(all P＞0.05). Conclusion AMI was the major diseases threatening human life,different age had its own clinical characteristics of patients,and it could not be impacted by gender.
