Additionally, a sex, group of age and race matched disease controls 'CATH-NOCA' composed of women and men with stable angina referred for cardiac catheterization, will be enrolled. Blood obtained during the initial catheterization and 2 months post-MI will be utilized for platelet testing.
Inclusion Criteria: * Acute ischemic symptoms compatible with diagnosis of MI, such as chest pain or anginal equivalent symptoms at rest or new onset exertional anginal equivalent symptoms * Objective evidence of MI (either or both of the following): * Elevation of troponin to above the laboratory upper limit of normal (ULN) * ST segment elevation of ≥1mm on 2 contiguous ECG leads * Willing to provide informed consent and comply with all aspects of the protocol * Administration of aspirin at least 1 hour before cardiac catheterization * Administration of thienopyridine (e.g., clopidogrel…
