What are the outcomes of coronary artery surgery in patients with poor left ventricular function?
The outcomes of coronary artery surgery in patients with poor left ventricular function were studied in the Coronary Artery Surgery Study (CASS) Registry, which found that long-term survival of medically treated patients was significantly better than for those who underwent revascularization surgery. In addition, Miller et al. found that patients with impaired left ventricular function, one- or two-vessel coronary artery disease, and severe ischemia had better outcomes with medical therapy than with revascularization. Alderman et al. also found that the results of coronary artery surgery in patients with poor left ventricular function were favorable.
