Implication

May augment wall motion analysis for CAD detection on stress echo; hypothesis-generating and requires prospective validation before practice change.

P
Population
67 subjects, including 14 with normal coronary anatomy and 53 with significant coronary disease.
I
Intervention
Systolic left ventricular long axis function analysis during dobutamine stress echocardiography.
C
Comparator
Wall motion analysis during dobutamine stress echocardiography.
O
Outcome
Detection of significant coronary artery stenoses (sensitivity and specificity).surrogate

Long axis function analysis during dobutamine stress echocardiography provides a quantitative adjunct to traditional wall motion analysis, improving sensitivity for detecting coronary ischemia, particularly in multivessel disease.
