DOBUTAMINE STRESS TEST (DOBUTAMINE STRESS ECHO, STRESS TEST) \u00a0<\/strong><\/p>\n

ABOUT THE TEST:<\/h2>\n

\"A<\/a>A dobutamine stress test (stress echocardiography using dobutamine) is a non-invasive test (one that does not damage the body’s tissues) that involves monitoring the heart’s function using an echocardiography machine as the workload on the heart changes. During the test, dobutamine is given intravenously. This medicine speeds up the heart rate by increasing the volume of blood that the heart pumps into the blood vessels in one minute. Stress echocardiography combines two-dimensional echocardiography (a heart ultrasound scan) with an exercise electrocardiogram (exercise ECG stress test), which is why it is often presented as an alternative to an exercise stress test.<\/p>\n

WHAT THE TEST INVOLVES:<\/h2>\n

A dobutamine stress echo involves monitoring the heart’s function using echocardiography. Before the test, an intravenous cannula is inserted. During the test, the patient receives dobutamine intravenously, a medicine that increases the strength of the heart muscle’s contractions. Dobutamine produces a state in the body similar to that following physical exertion. The medicine is administered gradually, starting at a dose of 10 \u00b5g\/kg\/min, which is increased every 3 minutes by 10 \u00b5g\/kg\/min until a maximum dose of 40-50\u00b5g\/kg\/min is reached. This allows successive echocardiographic images of the heart to be recorded as the workload on the heart changes. The test is performed in a suitably equipped consulting room at ETER-MED branch no. 1 in Gda\u0144sk, at ul. Jask\u00f3\u0142cza 7\/15 (ground floor), under the constant supervision of the cardiologist performing the test. The test takes approximately half an hour.<\/p>\n

PURPOSE OF THE TEST:\"An<\/a><\/h2>\n

The purpose of a dobutamine stress test is to provoke a controlled shortage of oxygen in the heart muscle. It helps detect and assess the extent of heart muscle damage that may indicate coronary artery disease. The test can establish the presence and extent of myocardial ischaemia (an inadequate blood supply to the heart muscle), which occurs after dobutamine is given to people with the condition. In patients who have had a heart attack, stress echocardiography is highly valuable for assessing the viability of a particular area of heart muscle and predicting recovery of the left ventricle’s ability to contract in patients treated with primary angioplasty. An echocardiographic stress test also helps establish whether a patient with suspected or diagnosed heart disease should undergo coronary angiography or a procedure on the heart. It may also complement the results of an exercise ECG stress test.<\/p>\n
