Objectives: This study was conducted to examine the 30-day survival rate and prognostic factors of acute myocardial infarction (MI).
Methods: Two hundred patients with acute MI were recruited from the Kyungpook university hospital in Daegu city from 1 July 1997 to 30 June 1998. Data were collected by interviewing with a questionnaire and their medical charts were reviewed by cardiologists. The survival status of patients were followed by telephone interview.
Results: The 30-day case fatality rate (CFR) of acute MI was 9%. Prognostic factors significantly associated with CFR were age, smoking, total cholesterol, arrhythmia, aspirin treatment, and beta-blocker treatment by simple analysis (p<0.05); Above age 70 (21.6%) versus below age 70 (4.7%), non-smoker (22.0%) vs. smoker (4.7%), above cholesterol 200 mg/dL (2.2%) vs. below (14.5%), arrhythmia (29.0%) vs. no arrhythmia (5.3%), no aspirin (46.7%) vs. aspirin (6.0%), and no beta-blocker (22.6%) vs. beta-blocker (4.1%). In multiple logistic regression analysis, the significant prognostic factors were smoking, arrhythmia, and aspirin treatment (p<0.05). The relative risk of smoking (yes/no) was 0.43 (95% CI; 0.31∼0.69), arrhythmia (yes/no) 3.63 (95% CI; 1.25∼6.91) and aspirin (yes/no) 0.33 (95% CI; 0.11∼0.65), respectively.
Conclusion: The 30-day case fatality rate of acute MI was 9% and the significant prognostic factors were smoking, arrhythmia, and aspirin treatment.
