Group/Cohort |
---|
MINOCA
Women with myocardial infarction (MI) with demonstrated non-obstructive coronary artery disease during cardiac catheterization (less than 50% blockage in any major vessel).
|
MI-CAD
Women with myocardial infarction (MI) with demonstrated obstructive coronary artery disease during cardiac catheterization (50% or greater blockage in any major vessel) or previous history of percutaneous coronary intervention (PCI) or or coronary artery bypass graft (CABG).
|
CATH-NOCA
Women with stable angina that are age and race matched to women in the MINOCA arm that are clinically referred for cardiac catheterization
|
- Examination of Platelet Activity Markers [ Time Frame: 1 year ]
- Examination of Markers of Cardiovascular Disease Risk [ Time Frame: 1 year ]This will include additional examination of known thrombosis, Inflammation, metabolic disease, and lipids/lipoprotein markers.
- Cellular and molecular mechanism of myocardial infarction in women [ Time Frame: 1 year ]To further investigate this mechanism, recent advances in microRNA, RNA, DNA expression profiling, and plasma and serum collections will be used.
- Examination of non-coding and coding mRNA profiles in women with MI and matched controls [ Time Frame: 4 years ]Specific transcripts associated with platelet activation, plaque destabilization, and different cardiovascular diseases will be analyzed at the genetic level.

Ages Eligible for Study: | 21 Years to 99 Years (Adult, Older Adult) |
Sexes Eligible for Study: | Female |
Accepts Healthy Volunteers: | Yes |
Sampling Method: | Non-Probability Sample |
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

Exclusion Criteria:
- Recent use of vasospastic agents, such as cocaine, triptans, or ergot alkaloids (≤1 month)
- Alternate explanation for troponin elevation, such as hypertensive urgency, acute exacerbation of heart failure, chronic elevation due to kidney disease, pulmonary embolism, cardiac trauma
- Pregnancy
- Thrombolytic therapy for STEMI (qualifying event)
- Use of any of the following medications:
- Platelet antagonists (except aspirin and thienopyridines) within 7 days
- NSAIDs (e.g., ibuprofen, naproxen) within 3 days.
- Thrombocytopenia (platelet count <100,000)
- Thrombocytosis (platelet count >500,000)
- Anemia (hemoglobin <9 mg/dl)
- Hemorrhagic diathesis
