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]
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 pharmacological stimulation of heart rate. [ 1]
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 ...
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]
Coronary steal. Coronary steal (with its symptoms termed coronary steal syndrome or cardiac steal syndrome) is a phenomenon where an alteration of circulation patterns leads to a reduction in the blood flow directed to the coronary circulation. [ 1] It is caused when there is narrowing of the coronary arteries and a coronary vasodilator [ 2] is ...
In Wikidata. Selective serotonin reuptake inhibitors ( SSRIs) are a class of drugs that are typically used as antidepressants in the treatment of major depressive disorder, anxiety disorders, and other psychological conditions. SSRIs increase the extracellular level of the neurotransmitter serotonin by limiting its reabsorption (reuptake) into ...
Cardiac magnetic resonance imaging perfusion (cardiac MRI perfusion, CMRI perfusion), also known as stress CMR perfusion, [1] is a clinical magnetic resonance imaging test performed on patients with known or suspected coronary artery disease to determine if there are perfusion defects in the myocardium of the left ventricle that are caused by narrowing of one or more of the coronary arteries.
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]
