Myocardial reperfusion syndrome. Pathogenesis, clinic, diagnosis

The basics of pathogenesis, clinic and diagnosis of myocardial reperfusion syndrome are considered. Myocardial reperfusion syndrome is defined. Its relevance as one of the most poorly studied and formidable complications of cardiac reperfusion in myocardial infarction with elevation of the S-T segment has been explained. A brief review of the historical review of this problem and such types of manifestations of myocardial reperfusion syndrome as: diastolic myocardial dysfunction, post-reperfusion disturbances of the heart rhythm, the phenomenon of no-reflow and irreversible damage to the myocardium are briefly reviewed. The modern views on the pathological physiology of diastolic myocardial dysfunction, post-reperfusion damage to the myocardium, and the no-reflow phenomenon are analyzed. A review of current views on the pathological physiology of the development of post-reperfusion disturbances in heart rhythm is carried out. The clinical picture and the effect on the hemodynamics of such a manifestation of myocardial reperfusion syndrome as diastolic myocardial dysfunction are described. A brief description of the clinical picture of irreversible post-reperfusion damage to the myocardium is given. The clinical picture and types of post-reperfusion rhythm disturbances are described. The diagnostics of the no-reflow phenomenon has been analyzed in detail, the coronary angiographic scales for assessing thrombolysis in myocardial infarction and for assessing myocardial perfusion are graphically shown. A description of the basics of diagnosing post-reperfusion disturbances in heart rhythm, diastolic myocardial dysfunction, and post-reperfusion irreversible damage to the myocardium is given. A brief description of the known in the world literature predictors of the development of myocardial reperfusion syndrome is presented.
