The mortality rate of AMI is higher than other disease. The purpose of this study is to evaluate which factors can affect the early outcome of AMI in Korean. MethodsA retrospective clinical study was done on 555 consecutive patientsmalefemale , mean age 61.3 years with AMI who had been admitted to Dong-San Medical Center from January 1990 to May The subjects were devided into two groups. was dead patients during the in-hospital period 85 patients, 15.3, and I was living patients 470 patients, 84.7 wen they discharged from hospital. We compared clinical and laboratory results in both groups and analysed the cause of death according to the time of death during hospitalization. ResultsThe results were as follows1 The mean age and female percentage of 65.4 years, 43 were higher than I 60.5 years, 28. The mean of systolic/diastolic blood pressure and percentage of smoker of 108/65 mmhg, 48 were lower than I 125/76 mmhg, 65, significantly. 2 The degree of Killip classification was higher in class 129.4, II18.8, III21.2, IV30.6 than in I patients class 173.4, II13.6, III 8.7, IV4.3, significantly patients were died first day of hospitalization and the most common cause of death was cardiogenic shock 27 patients, 31. The most common cause of death within 1 week was cardiogenic shock, afterthen congestive heart failure. 4 The most common cause of death in Killip class I patients was ventricular tachycardia or ventricular fibrillation and in Killip class II-IV patients was cardiogenic shock. ConclusionThe risk of in-hospital death was higher in elderly, female sex, and patients with higher Killip classification. Cardiogenic shock was most common cause of death within 1 week, and was congestive heart failure after 1 week.
