Finding the specific etiology in myocardial infarction with non-obstructive coronary arteries disease (MINOCA) and the best therapeutic approaches – a case report

Abstract

Myocardial infarction with nonobstructive coronary arteries disease (MINOCA) is defi ned as a clinical syndrome with normal or near normal coronary arteries disease (stenosis severity revealed on angiography less than 50%), excluding other overt causes of myocardial ischemia such as cardiac trauma. Trials report an incidence between 5-10% among subjects with acute myocardial infarction (AMI). The optimal management and the outcome of this syndrome require the proper identification of the specific pathophysiologic mechanism. We report the case of a 67-year-old male presenting with the clinical and enzymatic picture of a myocardial infarction with ST segment elevation in the anterior territory with no significant coronary arteries stenosis on the angiography. Our case illustrates the importance of revealing the real underlying condition which is involved in producing the MINOCA syndrome, because this is the only strategy suitable for a correct treatment and a favorable outcome.
