With performance that is comparable to PET/SPECT and at times favorable compared to stress echocardiography
, it is now an essential tool for diagnosing ischemia and for determining the likelihood of success following myocardial revascularization.
On the other hand, dipyridamole may be used in pharmacologic stress echocardiography
but it is less frequently used because the mechanism of action is based on perfusion changes rather than straight effects on myocardial contractility.
Therefore, a downstream test was defined as any postindex cardiac imaging test (resting echocardiography, stress echocardiography
, CT, MRI, PET, or nuclear medicine).
This review evaluates whether the use of stress echocardiography
to assess disease severity and to determine the optimal time for either surgical or percutaneous intervention of mitral stenosis.

A meta-analysis of 14 studies that compared dobutamine stress echocardiography
with conventional coronary angiography in 901 women found an overall sensitivity of 72% and specificity of 88% for echocardiography.
, stress single-photon-emission computed tomography and electron beam computed tomography for the assessment of coronary artery disease: a meta-analysis of diagnostic performance.
Heywood Hospital also performs stress echocardiography
and nuclear medicine cardiac testing with SPECT imaging equipment, a diagnostic tool to look for evidence of blockages by examining the flow of a tracer fluid into the heart.
Researchers at the recent annual meeting of the American Society of Echocardiography report that taking ultrasound images of the heart during a stress test, a procedure called stress echocardiography
, is a better way to identify women at highest risk for coronary artery disease than by traditional stress tests and clinical risk factors.
It is based on the Detsky modified risk index and results of noninvasive testing such as dipyridamole thallium imaging or dobutamine stress echocardiography
Food and Drug Administration (FDA) has accepted for review the company's supplemental New Drug Application (sNDA) for DEFINITY([R]) (Perflutren Lipid Microsphere) Injectable Suspension for use in stress echocardiography
