Abstract:Согласно третьему универсальному определению инфаркта миокарда (ИМ), имеется несколько раз-личных механизмов развития некроза кардиомиоци-тов [1]. ИМ 1 типа обусловлен атеротромбозом, типы 4 и 5 связаны с проведением различного рода меди-цинских манипуляций (чрескожных коронарных вмешательств и коронарного шунтирования). ИМ 3 типа диагностируют у внезапно умерших пациентов при невозможности получения данных о повышении кардиоспецифических ферментов и при наличии предшествующей картины поражения миокарда [1].

HighlightsThe article describes the main differences between the types of myocardial infarction, in particular, differences between type 1 and type 2 myocardial infarction, the complexity of diagnosis and management of patients with myocardial infarction type 2, and summarizes data on the prevalence of patients with myocardial infarction type 2. The arguments supporting the need for further researches to differentiate various phenotypes of myocardial infarction are provided. AbstractDespite the high interest in the study of type 2 MI, many unresolved issues concerning diagnosis, criteria for diagnosis and, especially, therapeutic tactics remain unresolved. The available data regarding type 2 MI remain limited and inconsistent, and are based on sources that include the analysis of type 1 MI. According to various predictions, the prevalence of type 2 MI will increase even more. Type 2 MI management strategy should be patient-specific and in accordance with the etiology and pathogenesis, therefore, timely diagnosis, and MI differentiation according to universally accepted definitions is a relevant scientific topic and a practical necessity.Thus, summarizing all the above, we can say that type 2 myocardial infarction is a topic that encompasses many unresolved issues concerning diagnosis, patient management and further secondary prevention.

Currently, type 2 myocardial infarction is a rather significant problem, both in terms of diagnosis and treatment. Myocardial infarction without obstructive coronary artery damage occurs in 5-10 % of patients with a myocardial infarction. Optimal strategies for the diagnosis and treatment of patients with myocardial damage associated with non-thrombotic mechanisms have not yet been determined. The article describes a clinical observation of type 2 myocardial infarction on the background of vasospasm, as well as diagnostic and therapeutic tactics in this clinical situation. The main provisions: the patient was 22 years old in the cardiology department due to the pain syndrome behind the sternum for the first time in his life and an increase in body temperature to 37.5 C. From anamnesis: active bodybuilding, taking testosterone in injectable form. The electrocardiogram revealed changes in the type of transmural myocardial ischemia without the dynamics characteristic of myocardial infarction. Troponin I (quantitative test) — 2.1 ng/ml at laboratory reference values of 0.010-0.023 ng/ml. A diagnostic search was conducted for myocardial infarction and acute pericarditis. For the purpose of differential diagnosis, coronary angiography was performed, during which dynamic stenosis of the posterior descending artery was revealed. The decision to stent the vessel was not made. Echocardiography revealed areas of local contractility disorders. The data of the examination showed in favor of myocardial infarction without coronary artery obstruction (type 2). Taking into account the absence of occlusive-stenotic lesions of the coronary arteries, the presence of vasospasm, 1 platelet aggregation inhibitor, medium-dose statins, isosorbide dinitrate, calcium channel blocker, angiotensin-converting enzyme inhibitor was prescribed. Conclusion. Invasive tactics made it more likely to diagnose type 2 myocardial infarction and prescribe the most optimal drug therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
