Reverse remodeling after coronary revascularization in patients with ischemic heart disease: focused on change of infarct scar

Methods Twenty-four patients with severe LV dysfunction {ejection fraction (EF) <35% on echocardiography} underwent before and more than 6 months after surgical revascularization. The following variables were measured: LV volumes, EF, mass, absolute and relative infarction size, transmural extent of infarction, and wall thickness. All patients were classified into two groups: group I, presence of revere remodeling after revascularization; group II, absence of reverse remodeling group. A reduction of 10% or more in end-diastole and end-systole volumes were considered presence of reverse remodeling. Variables were compared between preoperative and postoperative MR scans in each group.
