What is a dobutamine stress echocardiogram?
A dobutamine stress echocardiogram (DSE) may be used if you are unable to exercise. Dobutamine is put in a vein and causes the heart to beat faster. It mimics the effects of exercise on the heart. During an echo, a transducer (like a microphone) sends out ultrasonic sound waves at a frequency too high to be heard.
Why do I need a dobutamine stress test?
Why do I need a stress test? This test helps your physician determine how your heart functions when it is made to work harder by injecting dobutamine. Dobutamine is a drug that has an effect on the heart similar to exercise.
What is the difference between lexiscan and dobutamine stress test?
Dobutamine is used to treat cardiogenic shock and heart failure. Lexiscan is given in preparation for a radiologic (X-ray) examination of blood flow through the heart to test for coronary artery disease. Dobutamine is a catecholamine and Lexiscan injection is a stress agent.
What are the risks of a dobutamine stress test?
Risks Associated with a Dobutamine Stress Echocardiogram Severely high blood pressure. Irregular heartbeats. Dizziness. Nausea and extreme fatigue.
What does dobutamine do to the heart?
Dobutamine is a cardiac inotrope useful in the acute treatment of congestive heart failure. Dobutamine improves cardiac output, decreases pulmonary wedge pressure, and decreases total systemic vascular resistance with little effect on heart rate or systemic arterial pressure.
What are the side effects of dobutamine?
Common side effects of dobutamine include:
- increased heart rate and increased blood pressure,
- ventricular ectopic activity,
- nervousness,
- headache,
- nausea,
- vomiting,
- palpitations,
- low platelet counts (thrombocytopenia), or.
How do you prepare for a dobutamine stress echo?
Diabetic patients follow normal regimen, but eat light. You may have juice before the test if needed. No smoking or exercise 8 hours before testing. No caffeine 12 hours prior to testing (this includes colas, chocolate, tea, or coffee and all products labeled decaffeinated or caffeine free).

What is the best cardiac stress test?
Nuclear stress testing also uses heart imaging….Nuclear Stress Testing
- It is the most accurate type of stress test for finding CAD.
- It can find modest changes in blood flow.
- It is easier to interpret the images in people with baseline heart problems.
- It is rare for images to be inadequate for interpretation.
What is the difference between a stress test and a stress echo?
A stress echo is a more dynamic test that examines the heart in action. It combines an ultrasound of the heart with a stress test. A stress test, often called a treadmill test, measures how your heart works when experiencing added workload or “stress” of exercise.
Is dobutamine a high risk medication?
