OBJECTIVES: Mortality rate due to cardiovascular diseases is in the first place among the causes of death (36600 deaths) in the Republic of Kazakhstan (RK). Chest pain units (hereinafter - CPU) - are units for the treatment of chest pain and are defined as a units of short stay with special treatment protocols which the diagnosis of patients with chest pain in the emergency room and reduces unnecessary hospitalizations and medical costs. In the RK, the CPU department was first opened at the National Scientific Medical Center (NSMC) and functioned in the period from 2018-2020.

METHODS: A cross-sectional study was perfomed. The total number of patients was 2656. As a control group, patients treated in the period 2015-2017 in the amount of 1584 patients were taken.

RESULTS: During the indicated period, 2656 patients diagnosed with ACS were hospitalized, PCI was performed in 844 patients (31.8%), PCI with stenting - in 1089 patients (41%), CABG - 428 (16.1%). The comparison group consisted of 1584 patients diagnosed with ACS, of which 595 patients (37.6%) underwent diagnostic PCI, 512 patients (32.3%) underwent PCI with following stenting, and 199 (12.6%) underwent CABG. The detection of ACS increased by 67%, a decrease in cases of unreasonable hospitalization by 5.8%, a decrease in hospital’s day of reasonable coronary stenting by 8.7%, in the context of myocardial revascularization by CABG by 3.5%.

CONCLUSIONS: Due to the work of CPU department, the total number of reasonably hospitalized patients has increased by 67%, which in the long term leads to a decrease in the number of unnecessary hospitalizations, and therefore boost up the efficiency of cardiological care for the population.
