dobutamine stress echocardiography
Pronunciation: doh-BYOO-tah-meen
Also written as: DSE — dobutamine stress echocardiography
Pharmacologic stress test using dobutamine infusion with echocardiographic monitoring to detect coronary artery disease.
Full Definition
Dobutamine stress echocardiography (DSE) is a non-invasive diagnostic test that combines pharmacologic stress with echocardiographic imaging to detect coronary artery disease and assess myocardial viability. Dobutamine, a synthetic catecholamine, is infused intravenously in incrementally increasing doses to increase heart rate, blood pressure, and myocardial contractility, thereby increasing myocardial oxygen demand. Echocardiographic images are obtained at baseline, during stress, and in recovery to assess for new or worsening wall motion abnormalities that suggest ischemia. DSE is particularly useful in patients who cannot exercise adequately or when exercise stress testing is contraindicated. The test can also evaluate myocardial viability in patients with known coronary disease and reduced left ventricular function.
Usage
Usage note: Commonly abbreviated as DSE; specify maximum dobutamine dose achieved and reason for test termination.
