Coronary Artery Bypass Grafting in advance aged patients

INTRODUCTION: This study aimed to assess the impact of coronary artery bypass grafting (CABG) on outcomes in elderly patients compared to younger patients. METHOD: An observational case-control study was conducted involving 535 patients, divided into two groups: older adults (≥75 years) and younger adults ( 75 years). All patients underwent CABG following a similar protocol. The primary endpoints focused on early post-procedure outcomes, including in-hospital mortality and the duration of ICU or hospital stay. Patients were followed up for six months, and secondary study endpoints included long-term mortality, left ventricular ejection fraction, re-hospitalization rates, and repeated revascularization. RESULTS: 535 patients who underwent CABG were enrolled in this study. The smoking habit was significantly higher among younger adults (38.2% vs. 12.5%, P=0.001). Hypertension was more prevalent among older adults than younger adults (75% vs. 60%, P=0.044). LDL cholesterol serum levels were higher among younger adult patients (94.9 ±32.5 vs. 80.9 ±32.9, P=0.028). In-hospital death was not significantly different between younger and older adults (2.8% vs. 5.0%, P=0.34). Mortality in the six-month follow-up was non-significantly higher in the elderly (2.1% vs. 8.1%, P=0.06).A significant proportion of patients in both groups (46.9% in younger patients vs. 40% in older ones, P=0.40) received dual antiplatelet therapy (DAPT) prior to CABG due to a recent myocardial infarction and receipt of a new stent, but without increased major bleeding in both groups.CONCLUSION: CABG should be considered a viable treatment option for elderly patients with acceptable operative risk in current clinical practice.
