Type 2 MI is a form of MI that is not associated with coronary atherothrombosis, secondary to a condition that results in an imbalance between myocardial oxygen intake and oxygen consumption. Type 2 MI can be caused by coronary artery spasm, coronary microvascular dysfunction, embolism, dissection of coronary arteries, aorta, bradyarrhythmia, tachyarrhythmia, respiratory failure with severe hypoxemia, anemia, blood loss, hypotension/shock of other etiology, severe hypertension, surgical interventions. Type 2 MI accounts for 270% of all cases of MI. More often type 2 MI occurs in women, elderly, severe, comorbid patients. Type 2 MI is <em>ST </em>segment elevation MI in 324% of patients and non-<em>ST </em>elevation MI in others. Coronary angiography (and autopsy) in type 2 MI reveals coronary atherosclerosis in 2590%, but there is no coronary artery thrombosis. Mortality in patients with type 2 MI is generally higher than in patients with type 1 MI. This article is devoted to the problem of diagnosis and management of patients with type 2 myocardial infarction.</p>cardiac muscle necrosismyocardial infarctiontroponinischemia and myocardial injuryatherothrombosisinconsistency in the delivery and consumption of myocardial oxygenprognosistreatmentmyocardial infarction type 2periprocedural infarctionнекроз/повреждение сердечной мышцыинфаркт миокардатропонинишемия и повреждение миокардаатеротромбознесоответствие доставки и потребления кислорода миокардапрогнозлечениеинфаркт миокарда 2-го типаперипроцедурный инфаркт
