Prediction of long-term reverse left ventricular remodeling after revascularization or medical treatment in patients with ischemic cardiomyopathy: A comparative study between SPECT and MRI.

摘要

We designed a prospective study evaluating the ability of MRI and SPECT to predict reverse LV remodeling in long-term follow-up after CABG, with the aim to find parameters with the highest predictive value.We pre-screened 115 consecutive patients with LV ejection fraction <40%, all of whom were candidates for CABG based on coronary angiography findings of mul-tivessel disease. All patients had stable LV dysfunction, patients who experienced myocardial infarction during the 6 months prior to admission were not included in the study. Patients with acute coronary syndromes or any signs of an acute myocardial ischemia, as well as patients with significant valvular disease, chronic atrial fibrillation and contraindications to MRI (claustrophobia, implanted pacemaker or ICD), were also excluded. No re-do CABG patients were included in the study.
