↵* Cochran–Armitage, two-sided test for linear trend. Note p values remain unchanged if the highest troponin group is excluded from the test, with the exception of recurrent myocardial infarction (MI), where the p value becomes 0.13.
↵† Analysis for new-onset congestive heart failure was confined to patients with no signs or symptoms of heart failure.
↵‡ Analysis for cardiogenic shock was confined to patients who did not present with cardiogenic shock, and analysis for cardiac arrest/ventricular fibrillation (VF) or sustained ventricular tachycardia (VT) was confined to patients who did not present with cardiac arrest.
