Data presented as n (%). CK-MB, CK-MB = creatine kinase-myocardial band; PCI, percutaneous coronary intervention. * No clinical symptoms or electrocardiography (ECG) evidence of ischemia. † Clinical evidence of ischemia and ECG/cardiac enzyme evidence of infarction. ‡ Cardiac enzyme or ECG evidence of infarction < 24 hours after enrolment, different from the enrolment event. § Identified by systematic review of ECGs without clinical evidence of reinfarction. ¶ Myocardial infarction at the time of death with clinical, ECG, or cardiac enzyme evidence.
