Baseline characteristics of the study population categorized into all, myocardial infarction, and non-myocardial infarction. Diagnoses are according to 4th UDEMI Thygesen et al. (27). Absolute and relative frequencies for binary variables; median, 25th and 75th percentile for continuous ones; relative frequencies in brackets, 25th and 75th percentile in parentheses. P-values calculated by a Fisher test for categorical variables and by a Mann–Whitney U-test for continuous variables comparing patients with MI and non-MI patients. Ischemic ECG defined as at least one of the following findings: T-wave inversion, ST-segment elevation, ST-segment depression.
