Assessment of regional long-axis function during dobutamine echocardiography
Why the study?
Does quantitative tissue Doppler measurement of long-axis function correlate with visual wall motion assessment and angiographic coronary artery disease during dobutamine stress echocardiography in patients with known or suspected CAD?
Population
104 patients with known or suspected coronary artery disease undergoing dobutamine stress echocardiography
Comparison
Quantitative tissue Doppler measurement of peak… vs Standard visual assessment of radial wall motion…
Design
Cross-sectional, Assessed off-line by an independent operator

Implication
Tissue Doppler parameters were associated with visual wall motion; hypothesis-generating for objective regional assessment in stress echocardiography.
Structured PICO
Does quantitative tissue Doppler measurement of long-axis function correlate with visual wall motion assessment and angiographic coronary artery disease during dobutamine stress echocardiography in patients with known or suspected CAD?
P
Population
104 patients with known or suspected coronary artery disease undergoing dobutamine stress echocardiography (DbE)
I
Intervention
Quantitative tissue Doppler measurement of peak systolic velocity (PSV), time to peak velocity (TPV) and strain rate (SRI) during dobutamine stress echocardiography
C
Comparator
Standard visual assessment of radial wall motion and coronary angiography
O
Outcome
Comparison of mean PSV, TPV and SRI values with visual wall motion assessment and the presence of coronary artery disease by angiographysurrogate
Quantitative tissue Doppler parameters (PSV, TPV, SRI) during dobutamine stress echocardiography correlate significantly with visual wall motion abnormalities and angiographic coronary artery disease, offering a potential objective analysis of regional myocardial function.
