Brief Summary:
The Women's HARP study is a multi-center, diagnostic observational study employing standardized imaging protocols in women with MINOCA (MI with Non Obstructive Coronary Arteries) to determine the underlying diagnosis in each participant. Participants will be followed for recurrent clinical events, every 6 months, for a maximum of 3 years.

Condition or disease Intervention/treatment
Myocardial Infarction Device: OCT Other: CMR

Detailed Description:

Women's HARP is a multi-center, observational study which enrolls women with MI who are referred for cardiac catheterization. Eligible participants with MINOCA (defined as no stenosis of >50% in any major epicardial vessel) will undergo optical coherence tomography (OCT) at the time of diagnostic angiography and cardiac magnetic resonance imaging (CMR).

Participants will also have the option to enroll in the HARP- Stress Ancillary Study and HARP-Platelet Sub-Study.

Group/Cohort Intervention/treatment
OCT and CMR imaging
Device: OCT
Optical Coherence Tomography (OCT): Intracoronary imaging for amount and type of plaque as well as plaque rupture, ulceration, dissection and/or thrombosis.

Screen failures with MI found to have obstructive CAD. Limited data collection for comparison to MINOCA cohort.
Other: CMR
Cardiac Magnetic Resonance Imaging (CMR): MRI of the heart to identify areas of infarction (damage) and/or edema (swelling).

Primary Outcome Measures :
  1. Proportion of women with MINOCA who have plaque disruption (any of the following: rupture, erosion, calcified nodule with thrombosis) [ Time Frame: 1 week ]

Secondary Outcome Measures :
  1. Proportion of women with MINOCA who have spontaneous coronary dissection. [ Time Frame: 1 week ]
  2. Proportion of women with MINOCA who have late gadolinium enhancement and/or myocardial edema [ Time Frame: 1 week ]
  3. Correlation of the presence and location of myocardial abnormalities on CMR with presence and location of plaque disruption on OCT among women with MINOCA. [ Time Frame: 1 week ]
  4. Proportion of patients for whom an etiology can be clearly identified after combining OCT and CMR. [ Time Frame: 1 week ]
  5. Area under curve of clinical prediction model for plaque disruption on OCT in women with MINOCA. [ Time Frame: 1 week ]

Other Outcome Measures:
  1. Composite clinical endpoint: Death, unstable angina, stroke, recurrent MI, catheterizations and revascularization, other cardiac hospitalization. [ Time Frame: 3 years ]
    components of composite will also be examined

  2. Perceived stress [ Time Frame: 1 week ]

Layout table for eligibility information
Ages Eligible for Study:   21 Years to 99 Years   (Adult, Older Adult)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Women with MI and no coronary stenosis of 50% or greater on angiography, consecutive.

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
    • ST segment elevation of ≥1mm on 2 contiguous ECG leads
  • Willing to provide informed consent and comply with all aspects of the protocol
  • Age ≥ 21 years
  • Female sex

Exclusion Criteria:

  • Stenosis ≥50% of any major epicardial vessel on invasive angiography, as determined by the angiographer at the time of clinically ordered cardiac catheterization
  • History of known obstructive coronary artery disease at angiography, including history of percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG)
  • 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
  • Coronary dissection apparent on angiography
  • Excessive coronary tortuosity which, in the angiographer's opinion, increases the risks of OCT
  • eGFR<45 or contraindication to additional contrast needed for OCT in the opinion of the angiographer or treating physician
  • Contraindication to MRI (including but not limited to ferromagnetic implants)
  • Pregnancy
  • Thrombolytic therapy for STEMI (qualifying event)
