Distribution of patients based on the positivity for two cardiac markers. Five hundred and ninety-six patients (22.3%) had elevated BNP and/or cTnI concentrations. The 99th percentile of cardiac troponin I is 0.02 ng/mL, and hence, values ≥0.03 ng/mL were considered to be positive. The cutoff for BNP is 100 pg/mL. Abbreviations: BNP, B-type natriuretic peptide; cTnI, cardiac troponin I.
