Occurrence of cardiac death or non-fatal AMI at a medium of 28 months’ follow up in patients with troponin T < 0.10 μg/l and no ST-VM episodes (A, n = 97), troponin T < 0.10 μg/l and ⩾ 1 ST-VM episodes (B, n = 24), troponin T ⩾ 0.10 μg/l and no ST-VM episodes (C, n = 47), and troponin T ⩾ 0.10 μg/l and ⩾ 1 ST-VM episodes (D, n = 45). A versus B, log rank p = 0.43; A versus C, log rank p = 0.09; A versus D, log rank p = 0.0001; B versus C, log rank p = 0.61; B versus D, log rank p = 0.02; C versus D, log rank p = 0.01.
