Patients with acute myocardial infarction admitted to our hospital between 1984 and 1998 were divided into 4 groups by the way of recanalization and clinical characteristics were evaluated. The parameters which showed no change among the 4 groups are as follows: mean age of the onset, distribution of the number of patients in the onset season and time, infarct location, severity of Killip classification, and incidence of fatal arrythmias. The parameters which showed an increase among them are as follows: annual number of patients, age of maximum number of patients, number of patients from local area, extent of coronary artery disease, number of patients admitted within 6 hours, rate of recanalization therapy and its success rate, amount of peak creatin kinase, incidence of ventricular premature beat, rate of revascuralization in delayed stage and occupancy of coronary angioplasty, and percentage of heart failure and shock in the cause of death. Mortality rate decreased gradually, but the prevalence of smoking and hyperlipidemia as coronary risk factors was higher in younger aged people than older and the difference between the 4 groups was small. Parameters which related significantly to in-hospital death were as follows: age, infarct site, reperfusion therapy, heart failure, fatal arrythmia, and hyperlipidemia. Coordination between hospital and clinic, patient education, and progress of treatment improved prognosis of acute myocardial infarction.
Furthermore, it is important to minimize the high prevalence of coronary risk factors in younger age for the primary prevention of acute myocardial infarction.
