What is a Dobutamine Stress Echocardiogram (DSE)?

A Dobutamine Stress Echocardiogram (DSE) is a diagnostic test used to evaluate how well your heart functions under stress. Instead of exercising, a medication called dobutamine is administered to make your heart beat faster and harder, mimicking the effects of exercise. Ultrasound images of your heart are then taken to assess its performance.

What to Expect:

Preparation

• You may be asked not to eat or drink anything for a few hours before the test.
• Inform your doctor of any allergies, medications, or existing medical conditions.
• Wear comfortable clothing and avoid caffeine on the day of the test.

During the Procedure

• You will lie on an examination table, and electrodes will be attached to your chest to monitor your heart's activity.
• An intravenous (IV) line will be inserted into your arm to administer dobutamine.
• A technologist will apply a gel to your chest and use a transducer to take initial ultrasound images of your heart.
• Dobutamine will be gradually administered through the IV, increasing your heart rate.
• Additional ultrasound images will be taken at various stages to monitor your heart's response.
• The procedure usually takes about 1 to 2 hours.

After the Procedure

• You will be monitored until your heart rate returns to normal.
• You may feel a bit tired or have mild side effects, such as headache or nausea, which should subside shortly.

What are the benefits of a dobutamine stress echocardiogram?

A Dobutamine Stress Echocardiogram is performed to:

• Evaluate the function and structure of your heart under stress.
• Detect coronary artery disease and assess the severity of any blockages.
• Determine the effectiveness of treatments for heart conditions.
• Help plan future treatment strategies.

Benefits include the following:

• Provides valuable information about your heart's function and blood flow.
• Helps diagnose coronary artery disease and other heart conditions.
• Assists in assessing the effectiveness of current treatments.
• Non-invasive alternative to other stress tests that require physical exercise.
• Aids in developing appropriate treatment plans and improving patient outcomes.

What are the risks of a dobutamine stress echocardiogram?

While DSE is generally safe, there are potential risks, including:

• Temporary discomfort from the IV line and electrodes.
• Side effects from dobutamine, such as headache, nausea, or palpitations.
• Rarely, more serious complications such as abnormal heart rhythms, chest pain, or a heart attack.
