About this trial

To compare clinical outcomes of myocardial infarction with non-obstructive coronary arteries (MINOCA) according to the coronary microvascular dysfunction (CMD), evaluated by optical coherence tomography (OCT), invasive and non-invasive coronary physiologic assessment.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Subject with age ≥19 years and acute myocardial infarction

Rise and/or fall of cardiac troponin with one level >99 percentile plus ischemic signs/symptoms

Subject with non-obstructive coronary arteries

<50% diameter stenosis or

Disqualifiers

Subject with obstructive coronary arteries

Subject with alternate diagnosis including sepsis, pulmonary embolism, myocarditis, Takotsubo syndrome, spontaneous coronary dissection, and other cardiomyopathies.

Subject with cardiogenic shock or cardiac arrest ④ Subject who has non-cardiac co-morbid conditions with life expectancy <1 year ⑤ Subject or lactating women ⑥ Subject unable to provide consent

Trial population

About 150 patients with suspected myocardial infarction underwent invasive coronary angiography, but without obstructive coronary arteries will be enrolled. These patients will be evaluated by OCT, coronary functional assessment including coronary spasm test, invasive (FFR, CFR, IMR) and non-invasive coronary physiologic assessment (N-13 ammonia positron emission tomography).
