This clinical trial examines a higher than normal number of platelets, platelet genetic composition, and the effects of platelets in women who have had or are at higher risk for heart attack.
This is an observational, cohort, study, with a 6 month follow up. There is an estimated 200 participants. The study began in August 2016 and is expected to be completed by April 2020.
- Females, ages 21 to 99 years old
- Acute blood deficiency symptoms compatible with diagnosis of myocardial infarction (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, ticagrelor) at least 1 hour before cardiac catheterization
- Women with ≥50% of any major epicardial vessel on invasive angiography may participate
- 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, or cardic trauma
- Thrombolytic therapy for a full-blown heart attack, otherwise known as ST elevation myocardial infarction (STEMI
- 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
