If you have been recommended for a cardiopulmonary stress test, it means your care provider wants to see how your heart and lungs work under physical stress, such as during exercise.
What Goes on During the Test
Before the test, sticky patches connected to an electrocardiogram will be placed on your chest. You will then be asked to step on a treadmill – or get on a stationary bike – and exercise. As you exercise, a technician will monitor your heart’s electrical activity and oxygen levels through the electrocardiogram. A blood pressure cuff on one arm and a mouthpiece or breathing mask will also be in place to measure your oxygen levels.
Images of your heart while at rest and during exercise will be taken. The results of the cardiopulmonary stress test will determine your ability to exercise, and the results will be sent to your care provider to help him or her plan your treatment.
How to Prepare For the Test
If this is your first cardiopulmonary stress test, it is important to properly prepare for it. This information can serve as a guide, but if you have any more questions, don’t hesitate to reach out to the clinic where you’re having the test to ask.
Things to Avoid 48 Hours Before the Test
Avoid beta-blockers, or medications which reduce blood pressure, unless otherwise indicated by your physician.
Things to Avoid 24 Hours Before the Test
Avoid caffeinated products such as coffee, tea, chocolate. Decaffeinated tea and coffee still contain caffeine, and should be avoided. In addition, stay away from calcium channel blockers, unless otherwise indicated by your physician.
Things to Avoid 3 Hours Before the Test
After having a light meal, avoid eating or drinking anything except water for three hours before the test. If you are diabetic, ask your physician for specific instructions about insulin on the day of the test. Also bring a light snack with you to consume after the test.
On the Day of the Test
A cardiopulmonary test may involve stepping on a treadmill or an exercise bike. On the day of the test, make sure you are wearing comfortable clothes and athletic shoes for the exercise portion of the exam. Women should wear a supportive bra and comfortable pants or shorts in case the test involves an exercise bicycle. Avoid wearing makeup and nail polish. Avoid smoking or vaping, and engaging in strenuous activity on the day of the test.
Note on Medications
If you take medications for chronic health conditions, and also vitamins and supplements, make sure to discuss this with your physician. It is entirely possible that you can take all medications at the usual times unless otherwise instructed by the physician. The doctor will tell you what not to take before and on the day of the test. If this is the case, you should be able to resume taking all your medication as soon as after the test.
Patients who are unable to exercise for the exam will be given medication that will mimic the effects of exercise on the heart. In this case, you may be able to take all your medications as intended, unless the physician says otherwise.
