Abstract

Background. A resting echo showing a regional end-diastolic wall thickness ≤6 mm with a hyperechoic texture is pathognomonic of scar tissue and of non-viable myocardium. The aim of this study was to assess the prognostic value of the resting echo scar texture in patients with chronic ischemic cardiomyopathy evaluated prior to coronary artery bypass surgery. Methods. The preoperative clinical and echocardiographic data of 70 patients with a mean ejection fraction of 29.8 ± 4% scheduled for coronary revascularization were correlated to the cardiac events observed during a mean follow-up of 24 ± 12 months after surgery. Akinetic segments of the left ventricular wall with a reduced diastolic thickness and increased echoreflectivity were judged scarred. Results. Sixty-eight patients were discharged alive from hospital. On the basis of ROC analysis, we identified: group A (27 patients) with > 5 and group B (41 patients) with ≤5 scarred segments. There were 10 events (3 deaths, 4 heart transplants and 3 refractory heart failures), 8 in group A (29%) and 2 in group B (5%). At multivariate analysis the only independent predictor of the clinical outcome after revascularization was whether the patient was included in group A or B (Wald 6.3, p
