Background: Early postoperative myocardial infarction (MI) remains a critical complication following coronary artery bypass grafting (CABG). The intraoperative use of Doppler flowmetry could improve outcomes by ensuring optimal graft patency and flow. This study evaluated the effect of Doppler flowmetry on early postoperative MI in patients undergoing CABG.
Methods: This double-blinded, randomized controlled study included 120 patients who underwent elective CABG. Patients were divided into two equal groups: Group A underwent CABG with Doppler flowmetry, and Group B underwent CABG without Doppler flowmetry. The patients' ages ranged between 45 and 60 years old, with no difference in gender distribution between groups. The primary outcomes were early postoperative arrhythmias and echocardiographic parameters. Secondary outcomes included mechanical ventilation duration, ICU stay, and complication rates.
