Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
On-off study is a multicentre, prospective, randomized, parallel, trial.Patients indicated for elective or urgent isolated coronary artery bypass graft with additive European System for Cardiac Operative Risk Evaluation ≥ 6 were enrolled. Patients in cardiogenic shock were excluded. Patients were randomly assigned either to coronary artery bypass surgery with cardiopulmonary bypass (ON arm) or to off-pump coronary artery bypass graft (OFF arm). The composite primary end point included operative mortality, myocardial infarction, stroke, renal failure, re-operation for bleeding and adult respiratory distress syndrome, within 30 days after surgery. The total planned sample size was 693 patients; the actual number of enrolled patients was 411,according to the results of the interim analysis scheduled at 400 enrollments (alfa-spending=0.029, Pocock method).

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Off-pump bypass surgery
Off-pump coronary artery bypass graft (OPCAB) using mandatory a stabilization device and advisable, but not mandatory, a heart positioner
Off-pump bypass surgery
is a method of performing a coronary bypass operation for the purpose of treating advanced coronary heart disease while the heart is still beating normally.
On-pump bypass surgery
coronary artery bypass graft with cardiopulmonary bypass (CPB/CAB)
On-pump bypass surgery
is a technique that temporarily takes over the function of the heart and lungs during surgery, maintaining the circulation of blood and the oxygen content of the body.
