Characteristics of the clinical condition and results of surgical treatment of patients with coronary heart disease with lesions of the left coronary artery trunk, depending on the age of patients

Abstract

Aging of population is an important medical and social problem. Specialized care to this population group remains the leading task of modern cardiology and cardiac surgery. Aged patients with ischemic heart disease (IHD) and lesions of the left main coronary artery (LMCA) have comorbid conditions that receive much attention.

 The aim of the study was to conduct a comparative analysis of the clinical condition and surgical treatment of patients with damage to the left coronary trunk with coronary heart disease over 65 years of age.

Material and methods. Cases of surgical treatment were studied in the cardiac surgery department of the Kirov Regional Clinical Hospital in the period from 2018 to 2020. The study included cases of coronary artery bypass grafting in patients with coronary heart disease with damage to the trunk of the left coronary artery. All patients were divided into groups based on age. The clinical condition and results of surgical treatment in these groups were assessed. Conclusions are drawn based on the results of the study.

Results. Operated patients over 65 years of age had more severe comorbidities. In patients over 65 years of age, higher rates of intraoperative and early postoperative period were documented compared to younger patients.

 Hospital mortality among patients was 1.2% (n=2) and in both cases, death occurred in the group of patients over 65 years of age due to acute myocardial weakness complicated by multiple organ failure.
