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]
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]
Cardiogenic shock is caused by the failure of the heart to pump effectively. It is due to damage to the heart muscle, most often from a heart attack or myocardial contusion.[6] Other causes include abnormal heart rhythms, cardiomyopathy, heart valveproblems, ventricular outflow obstruction (i.e. systolic anterior motion in hypertrophic ...
Peripartum cardiomyopathy (PPCM) is a form of dilated cardiomyopathy that is defined as a deterioration in cardiac function presenting typically between the last month of pregnancy and up to six months postpartum. As with other forms of dilated cardiomyopathy, PPCM involves systolic dysfunction of the heart with a decrease of the left ...
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 ...
