Abstract
Objective. To study the prevalence of type II diabetes mellitus in patients with coronary heart disease who are to undergo coronary artery bypass grafting on a beating heart.
Materials and methods. The study included 991 patients: 786 (79.3%) men and 205 (20.7%) women aged 39 to 84 years, with a mean age of (64.3 ± 1.4) years. Men were aged 39 to 84 years, with a mean age of (62.7 ± 1.7) years, and women were aged 44 to 82 years, with a mean age of (66.0 ± 2.4) years. All study participants underwent coronary artery bypass grafting in the period from 2018 to 2021. The frequency of type II diabetes mellitus in different clinical groups of the study was analysed, taking into account its clinical course, compensation status and patient gender. Statistically, the data were processed using the χ² criterion with the Yates correction.
Results. It was found that the incidence of type II diabetes mellitus is 2.5 times higher in patients with coronary heart disease than in the general population. The prevalence of type II diabetes mellitus is statistically significantly higher in women with two and three or more coronary arteries.
Conclusions. The annual reports of the International Diabetes Federation and numerous scientific studies on type II diabetes mellitus prove that this pathology is extremely common, creates a risk of coronary heart disease, complicates its course, treatment and rehabilitation of patients. A statistical analysis of the prevalence of type II diabetes mellitus showed that in the cohort of patients to undergo coronary artery bypass grafting on a beating heart, it is statistically significantly more common in women with two and three or more coronary arteries affected.
