Clinical Relevance of Coronary Microvascular Dysfunction Assessments in Myocardial Infarction With Non-Obstructive Coronary Arteries
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.
• 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
⁃ fractional flow reserve (FFR) \>0.80 ③ Subject without previous history of coronary artery disease
∙ Subject who performed invasive coronary angiography within 24 hours after presentation ⑤ Subject who eligible for invasive and non-invasive coronary physiologic assessment
