Abstract
The aim – to analyze quality of life and long-term outcomes following revascularization of the left main coronary artery (LMCA) in elderly patients.
Materials and methods. This retrospective study included 200 patients with coronary artery disease aged 60 to 74 years, who underwent LMCA revascularization between September 2021 and July 2024. Patients were divided into two groups: Group A – percutaneous coronary intervention (PCI) (n=150) and Group B – coronary artery bypass grafting (CABG) (n=50). Quality of life was assessed using the Seattle Angina Questionnaire (SAQ).
Results. Both groups showed a reduction in the functional class of angina over a 12-month period (p=0.001 for both groups). The incidence of myocardial infarction, repeat revascularization, acute cerebrovascular events, and one-year mortality did not differ between groups. However, in Group A, adverse cardiovascular and cerebrovascular events were 12.7 % less frequent compared to Group B (p=0.034). According to SAQ results, all parameters improved in both groups. One month after the intervention, Group A showed significantly higher scores in physical activity limitation (p=0.002), treatment satisfaction (p=0.026), and disease perception (p=0.043) compared to Group B. No significant differences were observed between the groups at 6 and 12 months for these parameters.
Conclusions. The study demonstrated that PCI is associated with a lower frequency of adverse cardiovascular and cerebrovascular events compared to CABG, with similar functional class and complication rates. Both methods resulted in improved quality of life, with PCI showing better outcomes one month after revascularization.
