AGE PECULIARITIES OF COMORBID PATHOLOGY IN PATIENTS UNDERGOING PLANNED CORONARY ARTERYBYPASS GRAFTING

Abstract

Background: The number of elderly patients undergoing coronary artery bypass grafting (CABG) is increasing worldwide. Therefore, the assessment of comorbidities based on the age factor in patients with coronary artery disease (CAD) is highly relevant.Aim: To assess the associations between the age factor and comorbidities in patients undergoing CABG. Material and Methods: Data of 680 patients [538 (79.10%) men and 142 (20.90%) women], undergoing elective CABG in the period 2011-2012, included in the CABG Registry were used to detect comorbidities.All patients were enrolled into 4 age groups: below 50 years, 51-60 years, 61-70 years, over 70 years.Results: Aging was associated with an increase in the proportion of women suffering from arterial hypertension (AH), and multivessel disease. Similarly, the proportion of patients with higher func-tional class (FC) of angina, heart failure (CH), and heart rhythm disturbances increased. The number of patients referred to elective CABG with previous myocardial infarction (MI) was the highest among young adults (77%). Aging was associated with an increase in the number of patients with chronic pyelonephritis (44.30%) and thyroid pathology (3.40%).Conclusion: Patients’ aging is associated with an increase in cardiovascular comorbidities, but not MI. Importantly, there was no any increase in the rate of non-cardiovascular comorbidities.
