Cardiogenic shock in patients with acute coronary syndrome (data from Russian Federal Acute Coronary Syndrome Registry)

Mortality in acute coronary syndrome (ACS) and its complications remains high, despite significant advances in the treatment of coronary heart disease and its complications. One of the most life-threatening complications of ACS is cardiogenic shock (CS). CS is an extreme degree of acute heart failure and develops on average in 5-8% of patients hospitalized with ACS. In the present work, we analyzed data from Russian Federal ACS Registry - frequency of CS occurrence, treatment methods, and outcomes of ACS complicated by CS. Aim. Assess the quality of medical care in patients with ACS, which complicated by CS, and its compliance with current clinical guidelines. Materials and methods. Data from patients with ACS were exported from the Russian Federal ACS Registry. The study analyzed the data of 29.736 patients with ACS entered into the registry system in the period from 01.01.2018 to 31.12.2018. Of the 29.736 patients with ACS, 824 patients were diagnosed with CS. To assess the quality of care provided to patients with ACS and CS, the main clinical gguidelines were used. Results. The group of 824 patients with ACS and CS was analyzed. Among them patients with ACS with ST segment elevation prevailed 77.8% (n=641). According to Russian Federal ACS Registry 44.3% (n=365) of patients with ACS and CS received conservative treatment, of which 58.6% (n=108) were with ACS with ST segment elevation. Percutaneous coronary intervention was performed in 39% (n=321) of patients, of whom 89.4% (n=271) of patients with ACS with ST segment elevation. According to the data of this study, thrombolytic therapy was performed in 26.5% (n=218) of patients. Conclusion. The data obtained demonstrated that patients with ACS and CS did not receive optimal medical care and their treatment does not fully comply with modern clinical guidelines.
