End-diastolic wall thickness as a predictor of recovery of function in myocardial hibernation: Relation to rest-redistribution Tl-201 tomography and dobutamine stress echocardiography

摘要: Abstract OBJECTIVES The study assessed whether end-diastolic wall thickness (EDWT), measured with echocardiography, is an important marker of myocardial viability in patients suspected hibernation, and it compared this index to currently established diagnostic modalities dobutamine stress echocardiography (DSE) rest-redistribution thallium-201 (Tl-201) scintigraphy. BACKGROUND Because necrosis associated thinning, preserved EDWT may provide a simple that readily available from the resting echocardiogram. METHODS Accordingly, 45 stable coronary artery disease ventricular dysfunction underwent rest 2D echocardiograms, DSE Tl-201 tomography before revascularization repeat echocardiogram ≥2 months later. RESULTS Global motion score decreased 2.38 ± 0.73 1.94 0.82 after (p 0.6 cm had sensitivity 94% specificity 48% for recovery function. Similarly, maximal uptake ≥60% 91% 50%. Receiver operating characteristic curves prediction regional global function were similar maximum uptake. Combination any contractile reserve during improved 77% without significant loss (88%). CONCLUSIONS End-diastolic can predict Importantly, measurement ≤0.6 virtually excludes potential valuable adjunct assessment viability.
