CARDIAC STRESS TESTS-ECHO

CARDIAC STRESS TESTS-ECHO

1. The stress echo is a widely used test for myocardial ischemia by the detection of stress-induced wall motion abnormalities.

2. Less sensitive but more specific than MPI for the detection of coronary artery disease.

3. Use exercise/dobutamine to achieve target HR, then echo images to evaluate changes in wall motion, systolic wall thickening, and systolic ejection fraction.

4. Abnormal wall motion or failure of the wall to thicken (contract) appropriately suggests ischemia of that region of the myocardium.

5. Vasodilators are not used for stress echo.
