Levosemindan Versus Intra-Aortic Balloon Pump In low Ejection Fraction CABG Patients

Abstract

The postoperative low cardiac output is one of the most important complications following cardiac surgery especially in patients with severely impaired left ventricular function and is associated with increased morbidity and mortality. The condition requires inotropic support to achieve adequate hemodynamic status and tissue perfusion. Recent advances in perioperative anesthesiology management, surgical procedures, and myocardial protection methods have conferred improved results; consequently, a greater number of patients with severe LVD are referred for CABG. Studies from different cohorts assessing the efficacy of surgical revascularization have demonstrated that these patients benefit the most from CABG, particularly if symptoms of angina rather than heart failure are evident. (25) CABG in patients with severe left ventricular dysfunction keep the remaining viable myocardium, prevents additional myocardial deterioration, and induces the recovery of the systolic function of hibernated and ischemic myocardial segments
