RESULTS AND ADVERSE OUTCOMES AFTER PERCUTANEOUS CORONARY INTERVENTION: HISTORICAL COHORT STUDY

Percutaneous coronary intervention (PCI) is developed in Kazakhstan very quickly for many years. But there is no information about outcomes of PCI. The objective of this study was to analyze the outcomes after percutaneous coronary interventions in two regions Kazakhstan during 2012-2018 years. This registry-based historical cohort study obtained data on all patients who underwent PCI in East Kazakhstan and Pavlodar regions of Kazakhstan. Data are presented as the means ± standard deviation or as frequencies and percentage. The incidence rates were calculated as the number of cases per 100000 person-years of follow-up and 95% CI. A multivariate logistic regression analysis was utilized to find the independent predictors for in-hospital mortality. A total of 11931 subjects were undergone of PCI. Of these, 8349 (70,0%) were male, 3582 (30,0%) were female. A total of 320 patients (2,7%) died after the PCI during in-hospital period. Patients who died in-hospital period were predominantly male (55,9%), mean age 67,8 (9,71) years. Mortality rate was higher in women, and patients who were sent by other medical Institution and in patients with diagnose cerebral infarction. In-hospital mortality rate was higher in women than in men and in patients aged 70 years and elder. Independent predictors of in-hospital mortality for patients were age, gender, way of hospitalization, diagnose.
