Myocardial Infarction With Non-obstructive Coronary Arteries – Diagnosis and Management

Early coronary angiography performed during acute MI (AMI) identifies an occluded vessel in most patients with ST elevation MI (STEMI)1 and less frequently in those with non-STEMI;2 however, ≥90 % of patients with AMI have evidence of obstructive coronary artery disease.3 For these patients with overt coronary artery disease (CAD), the benefits of reperfusion strategies and cardioprotective therapies are well established and appropriate considering the documented atherothrombotic process involved.
