Comparison of Coronary Artery Bypass Surgery Results in Patients under 40 and over 80

Purpose: Coronary artery disease incidence under 40 years age is increasing parallel with atherosclerotic disease at the present day while it’s seen frequently over 40. We compared the preoperative risk factors and early postoperative results of patients under 40 years age with those over 80 years age executed coronary artery bypass surgery in our clinic in this retrospective study. Patients and method: 128 patients (106 patients under 40 years age (Group 1) and 22 patients aged over 80 (Group 2)) executed coronary artery bypass surgery between January 2004 and June 2012 in our clinic are included in this study. Result: Mean age was 45.2 ± 17.2. Smoking, diabetes mellitus and high low density lipoprotein levels were the predisposing risk factors in Group 1 while hypertension and chronic obstructive pulmonary disease are predominated in the other. All patients are taken to surgical procedure under elective conditions. Aortic cross clamp duration were 37.02 ± 16.2 and 38.9 ± 13.5 minutes respectively; total cardiopulmonary bypass interval was 67.1 ± 26.3 minutes. Utilization of left internal mammarian artery was significantly higher (p = 0.01) in group 1 when compared in terms of graft management. Necessity of positive inotropic support (p = 0.033) and intraaortic balloon pump demand (p = 0.315) are found higher in Group 2. Atrial fibrillation, neurologic complications, delirium, wound infection, and postoperative revision demand are found significantly low (p = 0.136) in Group 1. There was no mortality in both groups. Discussion: Postoperative complications are seen more often in the elder group, while there was no significant difference in terms of mortality in both groups. Coronary revascularisation is safely practical in both young and elder patients with well early postoperative results and acceptable hospital mortality.
