Table 2.
Patient cardiac function of the Internal Validation Group Stratified by Acute myocardial infarction (AMI). Patients presenting with non-ST-elevation myocardial infarction (NSTEMI, n = 63) and ST-elevation myocardial infarction (STEMI, n = 92). Data are presented as the percent (%) of total or the 95% confidence interval, where applicable. Data are considered statistically significant if P ≤ 0.05, denoted by * and bolded text
