Mid-term outcomes of surgical myocardial revascularization using coronary endarterectomy in diffuse coronary artery disease

Abstract

Aim. To evaluate the mid-term outcomes of surgical myocardial revascularization in combination with coronary endarterectomy in patients with diffuse coronary artery disease (CAD).Material and methods. In this cohort, non-randomized, retrospective, longitudinal study, we compared the mid-term outcomes of surgical myocardial revascularization in combination with coronary artery endarterectomy in patients with diffuse CAD with the outcomes of surgical myocardial revascularization without endarterectomy in patients without diffuse CAD. The study group included 93 patients, while the control group — 99 patients. Mid-term mortality, morbidity, and angiographic outcomes of surgical revascularization were assessed.Results. The mean follow-up period was 46,7±18,5 months. Mid-term mortality was 5,5% (n=5) in the coronary endarterectomy group and 3,1% (n=3) in the isolated coronary artery bypass grafting (CABG) group (p=0,486). Angina recurrence was noted in 14,3% (n=13) of patients in the endarterectomy group and in 14,4% (n=14) of cases in the isolated CABG group (p=0,977). Coronary artery stenting was required in the mid-term period in 4,4% (n=4) of patients in the endarterectomy group and 4,1% (n=4) (p=1000) in the isolated CABG group. A stroke in the mid-term period occurred in 1 (1,1%) patient of the study group and 3 (3,1%) patients in the control group (p=0,334). Graft patency in the anterior interventricular artery was 90,9%, while in the circumflex artery — 100% and in the right coronary artery — 80,4%. There were no significant differences in the patency level between the study and control groups. Quality of life did not differ significantly between groups in the mid-term period.Conclusion. Coronary endarterectomy is not associated with an increase in mortality and morbidity in the mid-term period, and is accompanied by satisfactory angiographic patency rates. There was no negative effect of coronary endarterectomy on the quality of life in the mid-term period.
