According to the Russian registry RECORD, the hospital mortality at STEMI in domestic hospitals remains high, which is due to the low frequency of reperfusion measures. There are problems in treatment patients of senile age. Comparative studies of the quality of care for patients with acute coronary syndrome were not conducted in Russia. 489 patients with STEMI, arrived in the first 24 hours from the onset of MI were analyzed. Quality of care for patients with STEMI was evaluated according to the quality criteria of the Association of Emergency Cardiovascular Care of the European Society of Cardiology. To compare the quality of care for patients of different age groups, the endpoints were the frequency of use of TLT and primary PCI, the incidence of cardiogenic shock, pulmonary edema, acute left ventricular aneurysm, and acute psychotic disorders. It is shown that patients with STEMI receive emergency medical care of high quality in adequate time. Elderly STEMI patients are less likely to undergo percutaneous coronary intervention, have more extensive myocardial damage with severe left ventricular failure and acute psychotic disorders, which is associated with a multiple increase in hospital mortality. The most frequent reasons for rejecting PCI were acute mental disorders, multivessel diffuse lesions of the coronary arteries with pronounced calcinosis, small diameter of the artery. It is necessary to develop new devices or techniques for PCI in conditions of severe multivessel lesions of coronary arteries with pronounced calcification, and also develop methods of neuroprotection in order to overcome existing barriers in providing emergency high-tech medical care to elderly STEMI patients.
