Myocardial Viability and Impact of Surgical Ventricular Reconstruction on Outcomes of Patients with Severe Left Ventricular Dysfunction Undergoing Coronary Artery Bypass Surgery: Results of the Surgical Treatment for Ischemic Heart Failure (STICH) Trial

摘要

ObjectiveIn the Surgical Treatment for Ischemic Heart Failure (STICH) trial, surgical ventricular reconstruction plus coronary artery bypass surgery was not associated with a reduction in the rate of death or cardiac hospitalization compared to bypass alone. We hypothesized that the absence of viable myocardium identifies patients with coronary artery disease and left ventricular dysfunction who have a greater benefit with coronary artery bypass graft surgery and surgical ventricular reconstruction compared to bypass alone.
