Dobutamine is a medication used in the treatment of cardiogenic shock (as a result of inadequate tissue perfusion) and severe heart failure. [ 2][ 3] It may also be used in certain types of cardiac stress tests. [ 2] It is given by IV only, as an injection into a vein or intraosseous as a continuous infusion. [ 2]
ICD-9-CM. 89.4. MeSH. D025401. MedlinePlus. 003878. [ edit on Wikidata] A cardiac stress test is a cardiological examination that evaluates the cardiovascular system's response to external stress within a controlled clinical setting. This stress response can be induced through physical exercise (usually a treadmill) or intravenous ...
Cardiac allograft vasculopathy. Cardiac allograft vasculopathy (CAV) is a progressive type of coronary artery disease in people who have had a heart transplant. [ 1] As the donor heart has lost its nerve supply there is typically no chest pain, and CAV is usually detected on routine testing. [ 2]
Strain rate imaging. Strain rate imaging is a method in echocardiography ( medical ultrasound) for measuring regional or global deformation of the myocardium (heart muscle). The term "deformation" refers to the myocardium changing shape and dimensions during the cardiac cycle. If there is myocardial ischemia, or there has been a myocardial ...
Echocardiography: A wall motion abnormality at rest which improves during a low-dose dobutamine stress test is classified as "hibernating myocardium." Low dose dobutamine stimulates contractile function and thus helps to predict functional recovery after revascularization. Cardiac magnetic resonance: The most frequently used MR contrast agents ...
Single-photon emission computed tomography. Single-photon emission computed tomography ( SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. [ 1] It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy ), [ 2] but is able to provide true 3D ...
Coronary ischemia, myocardial ischemia, [ 1] or cardiac ischemia, [ 2] is a medical term for abnormally reduced blood flow in the coronary circulation through the coronary arteries. [ 3] Coronary ischemia is linked to heart disease, and heart attacks. [ 4] Coronary arteries deliver oxygen-rich blood to the heart muscle. [ 5]
Certain medications, such as dobutamine and milrinone, improve the heart's ability to contract and can also be used. When these measures fail, more advanced options such as mechanical support devices or heart transplantation can be pursued. Cardiogenic shock is a condition that is difficult to fully reverse even with an early diagnosis. [4]
