What is Cardiac Stress Test

What is a Cardiac Stress Test?

A cardiac stress test is a diagnostic test to determine how well your heart is working under regular circumstances and in situations that may cause you stress. The exercise stress test or treadmill test is used to evaluate the heart’s response to physical activity.

Your doctor can identify potential problems with your heart and make recommendations for further evaluation or treatment if necessary. A stress test may be used to diagnose whether you have heart disease, arrhythmias, or other cardiac conditions.

A cardiac stress test may also be prescribed for patients who may not have any cardiac symptoms. Athletes who want to improve their fitness levels may benefit from a cardiac stress test. Patients with other cardiac conditions may also benefit from a cardiac stress test.

What are the Types of Cardiac Stress Test?

There are two main types of cardiac stress test: the exercise stress test and the pharmacological stress test.

The exercise stress test is the most common type of stress test. A cardiac stress test is a relatively safe and simple procedure. During an exercise stress test, you will walk on a treadmill or pedal a stationary bike for a gradually increasing amount of time.

Your heart will be monitored throughout the test using an electrocardiogram (ECG). Other measurements such as your blood pressure and oxygen levels, may also be monitored.

The pharmacological stress test is performed in cases where you may be unable to exercise due to health problems or other limitations. During this type of test, you will be given a medication through an IV that will make your heart work harder, like how it would work during exercise. Your doctor will monitor your heart’s electrical activity during the test by using an ECG and measuring your vital signs (blood pressure, pulse).  

What happens during an Exercise Cardiac Stress Test?

If you are experiencing any symptoms of heart disease (chest pain, shortness of breath, or fatigue), your doctor may recommend a cardiac stress test. The test can help your doctor diagnose the cause of your symptoms and develop a treatment plan for you.

Before your cardiac stress test, your doctor will perform a comprehensive evaluation of your health. This includes a medical history review, physical examination, and assessment of your risk factors for heart disease.

Before the test:

  • You may be asked to avoid consuming food, caffeine, or certain medications before the test.  These can interfere with the results of your test.
  • You should wear comfortable clothing (exercise pants and T-shirt) and appropriate footwear such as sneakers for the exercise portion of the test.

During the test:

  • The doctor will measure your vital signs (blood pressure, heart rate, ECG) at the beginning of the test when you are at rest and throughout the duration of the test.
  • The goal is to observe for any signs of cardiac abnormalities or physical distress.

During the exercise phase:

  • You will be asked to walk on a treadmill or pedal a stationary bicycle, gradually increasing the intensity of the activity over time.
  • The goal is to reach a target heart rate based on your age, physical fitness level, and medical history.
  • Your doctor will monitor for any signs of cardiac abnormalities or physical distress during the test.
  • The test will end when you have reached your target heart rate or experience any physical symptoms that warrant for your test to end. There are some risks involved during the exercise stress test, such as chest pain, dizziness, and fatigue. These risks are usually mild and temporary.
  • Please let your doctor know if you experience any discomfort during the test.

After the test

  • After your test, there is a post-exercise recovery phase.
  • You will enter a cool-down period to gradually decrease your activity level.
  • Your vital signs and ECG readings will be monitored by your doctor during the recovery phase.
  • After the test is completed, your doctor will review the results of the test with you.

It is important to take a proactive approach in preventing severe complications from heart disease by getting a cardiac stress test. Please consult your doctor if you have any questions.
