Stress Echocardiogram
What is a stress echocardiogram?
A stress echocardiogram is an investigative test that combines an echocardiography and a stress test. A stress test helps assess the capacity and reserve of the heart muscle by recreating a ‘stressful’ environment by exercising on a treadmill or bicycle. This information indirectly helps the cardiologist assess the blood supply to the heart muscles, viability and function of the heart muscle and to plan for the appropriate treatment plan.
When is a stress echocardiogram needed?
This non-invasive test is needed to help cardiologists diagnose any signs of coronary artery disease such as:
- Heart failure
- Heart valve disease
- Pulmonary hypertensio
Who will be recommended to do a stress echocardiogram?
Your doctor may recommend a stress echocardiogram if you display any symptoms of a heart disease especially if it worsens with activities. These symptoms include:
- Chest pains or discomfort
- Dizziness
- Shortness of breath
- Irregular heartbeat (arrhythmia)
Other individuals who may be recommended this test include:
- Athletes
- People who are about to undergo surgery
- People exposed to extreme conditions such as high altitudes
How should I prepare for a stress echocardiogram?
Before coming to the clinic, it is recommended to:
- Avoid consuming caffeine
- Avoid applying any lotions or oils on your skin
- Advisable to shave any chest hair so the ECG electrodes can be placed on your chest
- Take a light meal if your test is scheduled in the afternoon
- Bring your exercise attire (running shoes, socks and towel)
How is a stress echocardiogram conducted?
There are 3 stages to this test and the entire procedure may take around 1 to 2 hours.
Stage 1: Rest
- You will be asked to lie on your side where a basic echocardiogram will be performed.
Stage 2: Exercise
- After the images are taken and recorded during rest, you will be asked to change and proceed to walk on the treadmill.
- The speed and inclination of the slope will be programmed to increase every 2 to 3 minutes to gradually stress your heart.
- Once the targeted heart rate is reached or if you are unable to continue, you can proceed to lie on the couch for another round of scanning.
Stage 3: After exercising
- After the echocardiogram image is recorded, the images are then compared. This helps the cardiologist to observe and detect any abnormalities in the muscle function.
What happens after the stress echocardiogram?
If you are feeling unwell after the test, you will be monitored for some time and if the symptoms persist, you may be admitted for observation. Once the results have been reviewed, we will reach out to you to schedule a follow-up appointment, whereby the cardiologist will discuss the results, diagnosis and treatment plan if needed.
