Abstract
Introduction. Revascularization is an important therapeutic intervention in connection with its undeniable
beneficial effect on the symptoms, the prognosis of the disease. The prevalence of diabetes among patients
referred for myocardial revascularization, today is quite high, and according to various estimates as high as
35%. The study evaluated long-term results of coronary artery bypass grafting (CABG) in patients with multivessel
coronary artery disease and diabetes.
Material and methods. The study included 337 patients with multivessel coronary disease after CABG SC,
divided into 2 groups: Group 1 included 195 patients with diabetes mellitus, Group 2 included 142 patients
without diabetes (control). Analyzed all-cause mortality, non-fatal myocardial infarction, not fatal stroke,
the need for repeat revascularization, as well as the frequency of the collection of all events (the so-called
"major" cardiovascular complications).
Results. Long-term results of CABG in patients with diabetes mellitus were generally worse than in patients
without diabetes: lower overall survival (87.2 and 97.2%, respectively, p = 0.037), as well as lower survival
without myocardial infarction (87.2 and 95.8%, p = 0.029), stroke (85.6 and 93.7%, p = 0.017) and the need
for repeat revascularization (86.2 and 91.6%, p = 0.035). Five-year freedom from the development of the
"big" of cardiovascular complications in the group with diabetes mellitus was 51.8% in the group without diabetes
— 73.2% (p <0.001).
Conclusion. The results obtained in our study indicate that the long-term results of CABG in patients with
diabetes mellitus was significantly worse compared with the results of patients without diabetes, resulting in
a significant decrease in overall survival, as well as the increase in the incidence of long-term cardiovascular
complications.
