Key result
Ultrasonic strain during DSE distinguishes 3 distinct regional ischemic substrates in the same patient.
Why the study?
Differentiation between differing regional ischaemic substrates is crucial for decision-making in patients with coronary artery disease.

May differentiate ischaemic substrates by strain during stress echo; leaves open clinical adoption pending prospective validation.
The differentiation between differing regional ischaemic substrates is crucial for decision-making in patients with coronary artery disease. This study demonstrates that quantification of dobutamine stress echocardiography using ultrasonic strain measurement has the potential to identify three differing regional ischaemic substrates (ischaemic, stunned and scarred) in the same patient. The data were validated by traditional analysis of dobutamine stress echo, coronary angiography and correlative quantitative positron emission tomography information.

M Kowalski (2003) conducted an observational in Coronary artery disease. Quantification of dobutamine stress echocardiography using ultrasonic strain measurement vs. Traditional analysis of dobutamine stress echo, coronary angiography and quantitative positron emission tomography was evaluated on Identification of three differing regional ischaemic substrates (ischaemic, stunned and scarred). Quantification of dobutamine stress echocardiography using ultrasonic strain measurement identified three differing regional ischaemic substrates (ischaemic, stunned, and scarred) in the same patient.
