Myocardial infarction without obstructive coronary artery disease (MINORCA)

Abstract

«MINOCA» (myocardial infarction with nonobstructive coronary arteries) is a new term in cardiology, which combines a different group of pathological conditions, as a result of which myocardial infarction develops with non-obstructive coronary arteries. The article reveals the etiology and pathogenesis of MINOCA, which is divided into coronarogenic: non-obstructive atherosclerosis, coronary spasm, microvascular dysfunction, coronary artery dissection, muscle bridge and not coranorogenic: myocarditis, cardiomyopathy, thrombophilia, pulmonary embolism. The issues of diagnosis and differential diagnosis attract attention, which determines the further choice of management and treatment tactics. Currently, there are no recommendations for the management and treatment of patients with a diagnosis of MINOCA; accordingly, prevention methods have not been developed. The term «MINOCA» poses a number of questions for us, many of which remain open for further discussion and resolution.
