The aim – to compare clinical characteristics of patients with stable coronary artery disease and reduced left ventricular ejection fraction selected for coronary artery bypass grafting (CABG) and stenting, and evaluate changes of health-related quality of life after revascularization at 6-months follow-up.
Material and methods. The prospective study included 148 patients with coronary artery disease, heart failure and left ventricular ejection fraction less than 45 % sequentially selected for CABG (n=111) or stenting of coronary arteries (n=37).
Results. Group of patients selected for CABG was characterized by more frequent detection of ischemic stroke, recurrent myocardial infarction, left ventricular aneurysm, hemodynamically significant lesions of the left coronary artery trunk and three-vessel disease, lower left ventricular ejection fraction and larger values of left ventricular end-diastolic and end-systolic volumes.
Conclusions. During 6-months follow-up we observed advantages of the myocardial surgical revascularization as a most effective method of correction of myocardial structure and function. At the same time, similar improvement of health-related quality of life, assessed by three questionnaires (SAQ, MLHFQ, SF-36), was achieved in the compared groups. The reduction of angina functional class was a main factor of the quality of life improvement.
