Title: First myocardial infarction: Age and ejection fraction identify a low-risk group
Abstract: This study examines patients with a first myocardial infarction (MI) (about 70% of the population, n = 2089), and identifies factors associated with 1-year cardiac mortality in patients discharged alive. With the use of multivarate analysis of variabies observed at hospital discharge in patients with a first MI, age was the most important predictor, followed by left ventricular ejection fraction (LVEF) (determined in 56%) and other variables. Based on this finding, age subsets (≤50, 51 to 70, >70 years) were related to LVEF groups (≤0.40, 0.41 to 0.50, >0.50). Patients with a first MI who were <50 years of age with LVEF >0.40 and patients between 51 and 70 years of age with LVEF >0.50 had a very low risk for 1-year cardiac death, 1.2 ± 1.1% (95% confidence interval). Such patients comprised 47% of individuals with a first MI having an LVEF determination. Mortallty in the remaining patients <70 years was 7.4 ± 3.5%. Mortality for patients >70 years was high, 22.2 ± 6.6%. Thus with LVEF as the only predischarge test, a sizabie low risk group can be identified among patients with a first MI.
