Background: Off-pump coronary artery bypass grafting, avoiding
the use of cardiopulmonary bypass, has attracted the interest of an
increasing number of surgeons and patients, and has assumed an increasing
role in surgical practice. Whether Off-pump coronary artery bypass
grafting have better outcome in high-risk patients as compared to
Conventional coronary artery bypass grafting remains to be confirmed. We
describe an analysis of early clinical outcomes of high-risk CAD
patients, subjected to both techniques.
Methods: We studied 450 patients with additive EuroSCORE of ≥5 on
admission. Patients were divided into 2 groups; Group A was assigned for
patients underwent conventional coronary artery bypass grafting, and
Group B for patients underwent Off-pump coronary artery bypass grafting.
Data, including gender, age, demographic variables and postoperative
complications were extracted from the medical records.
Results: Both groups were matched with regard to age, gender, smoking,
Diabetes mellitus, dyslipidemia, renal hemodialysis and the mean Euro-
Score. We demonstrated a decrease in the incidence of early postoperative
AF and renal failure in the Off-pump group. However, we recorded no
statistical difference of neurologic complications, acute myocardial
infarction or early mortality between the two groups.
Conclusion: we recommend Off-pump coronary artery bypass grafting in
high-risk coronary disease patients, as this technique may carry
potential benefits without compromising their clinical outcomes.
