Abstract

Purpose of the study: to model the operative risk in patients with congenital heart defects, acquired valvular heart disease and ischemic heart disease using the stratification scales EuroSCORE and Aristotle Basic Complexity score. Ma-terials and methods. 559 patients, who were in inpatient treatment in the period from 2011 to 2019 were examined and underwent surgical correction before the surgery. Among them, 327 (58,5%) patients with various forms of congenital heart defects (CHD), 120 (21,5%) patients with isolated and combined acquired valvular heart disease (VHD) and 112 (20,0%) - with chronic forms of ischemic heart disease (IHD)..

Results. According to the Aristotle Basic Complexity score, the operative risk in patients with CHD averaged 6.6±3.8 points, which corresponded to the 2nd level of complexity. The operative risk according to the Aristotle Basic Complexity score in patients with CHD and complicated postoperative course was 8,35±4,1 points (3,0-17,5), and in patients with a smooth course of the postoperative period – 6,34±3,5 points (3,0-2,5) with statistically significant (p=0,002). EuroSCORE scale logistic parameters’s statistical analysis showed that in patients with acquired VHD and a smooth postoperative course, were significantly lower (approximately 3 times) and with a significant difference compared to patients with complicated course: 4,1±3,6% versus 12,9±14,0% (p=0,008). A similar state was observed while analyzing the logistic parameters of the EuroSCORE scale in patients with chronic forms of IHD: 3,6±3,4% and 8,8±10,2%, respectively (p=0,003).

Conclusion: The operative risk according to the Aristotle Basic Com-plexity Score in patients with different types of CHD is statistically significantly different in patients with a complicated and smooth postoperative course (p=0,002). The EuroSCORE stratification risk assessment scale presents certain possibilities for predicting the complicated course of the early postoperative period in patients with acquired VHD (p=0,008).
