Patent grafts linked to EF gains in asynergy; supports hypothesis but leaves open randomized validation of CABG benefit.
Does coronary artery bypass graft surgery improve regional and global left ventricular function in patients with preoperative asynergy?
Patent coronary artery bypass grafts improve regional and global left ventricular function in patients with depressed preoperative performance, while occluded grafts worsen function.
Wolf et al. (1978) studied this question.
