Abstract: Myocardial infarction refers to severe coronary artery stenosis, which leads to continuous and complete occlusion of coronary artery and myocardial necrosis. Coronary artery stenosis (>50%) or occlusion can be seen in 90% of patients undergoing coronary angiography, but 10% of patients have no obvious stenosis, that is, non obstructive myocardial infarction (MINOCA). The incidence rate of MINOCA was about 6%, showing an upward trend year by year, with an average age of 55 years, of which 40% of women. Its etiology is complex, the onset is urgent, and the clinical manifestations are complex and changeable. The incidence of major adverse cardiovascular events (MACE) is very high, and the mortality rate within one year is as high as 3.5%. There is no unified diagnosis and treatment plan at present. In this paper, the etiology, diagnosis and treatment of MINOCA were reviewed.
