Comparative analysis of the results of surgical treatment for patients with lung cancer and concomitant coronary heart disease after prophylactic myocardial revascularization and for patients with lung cancer without CAD

Introduction. Objective. The feasibility of prophylactic myocardial revascularization in planning non-cardiac surgical interventions remains as a subject of debate today.Purpose of the study. To compare the immediate and long-term results of surgical treatment of patients with lung cancer with concomitant CAD, when prophylactic myocardial revascularization was performed, with operated patients with lung cancer without CAD.Materials and methods. The study included 134 patients operated on for lung cancer, 126 (94,0 %) men and 8 (6,1 %) women, the mean age was 63,9 years (from 36 to 81). Of these, the main group: 63 (47 %) patients with concomitant CAD, when prophylactic myocardial revascularization was performed, and the control group: 71 (53 %) patients without concomitant CAD (or who does not need prophylactic revascularization).Results: the incidence of postoperative complications in the main and control groups was 33,3 % (21/63) and 25,4 % (18/71) (p=0,453), and mortality was 1,6 % (1/63) and 4,2 % (3/71) (p=0,385), respectively. Perioperative myocardial infarction in the main group was registered in 3,2 % (2/63) with a fatal outcome in 1,6% (1/63), and in the control group it was 0 % (0/71) (p=0,137; p=0,291).The overall 1-, 3-, and 5-year survival of radically operated patients in the main group was 81,7%; 67,6%; 50,0%, and in the control group - 86,8 %, 62,5 %, 53,8 % (p=0,750), respectively.Conclusions. Prophylactic myocardial revascularization in patients with lung cancer allowed achieving comparable immediate and long-term results of surgical treatment of patients with lung cancer with concomitant coronary artery disease and without it.
