Key result
Dobutamine echocardiography had 69% sensitivity and 100% specificity for predicting functional recovery in akinetic/dyskinetic segments, but sensitivity was lower (53%) in wall-thinned segments.

Dobutamine echo sensitivity drops in thinned segments warranting multimodal assessment; leaves open refinement of viability criteria in chronic CAD.

Does dobutamine echocardiography accurately predict post-revascularization functional recovery in patients with chronic coronary artery disease?
Dobutamine echocardiography has reduced sensitivity for predicting functional recovery after revascularization in akinetic/dyskinetic myocardial segments with thinned end-diastolic wall thickness.
Furukawa et al. (1997) conducted an observational in chronic coronary artery disease (n=53). Dobutamine echocardiography was evaluated on post-revascularization functional recovery. Dobutamine echocardiography had 69% sensitivity and 100% specificity for predicting functional recovery in akinetic/dyskinetic segments, but sensitivity was lower (53%) in wall-thinned segments.
