|Condition or disease||Intervention/treatment|
|Myocardial Infarction||Device: OCT Other: CMR|
HARP is a multi-center, observational study which enrolls men and 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-Platelet Sub-Study.

OCT and CMR imaging
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.
Cardiac Magnetic Resonance Imaging (CMR): MRI of the heart to identify areas of infarction (damage) and/or edema (swelling).
- Proportion of patients with MINOCA who have plaque disruption (any of the following: rupture, erosion, calcified nodule with thrombosis) [ Time Frame: 1 week ]
- Proportion of patients with MINOCA who have spontaneous coronary dissection. [ Time Frame: 1 week ]
- Proportion of patients with MINOCA who have late gadolinium enhancement and/or myocardial edema [ Time Frame: 1 week ]
- 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 ]
- Proportion of patients for whom an etiology can be clearly identified after combining OCT and CMR. [ Time Frame: 1 week ]
- Area under curve of clinical prediction model for plaque disruption on OCT in patients with MINOCA. [ Time Frame: 1 week ]
- Composite clinical endpoint: Death, unstable angina, stroke, recurrent MI, catheterizations and revascularization, other cardiac hospitalization. [ Time Frame: 10 years ]components of composite will also be examined
- Perceived stress [ Time Frame: 1 week ]
