6 Types of Cardiac Stress Tests: Treadmill, Nuclear, Echo & More

If your doctor has recommended a cardiac stress test,  there’s no need to worry; it simply checks how well your heart functions under stress. These tests are commonly used when someone has symptoms like chest pain, shortness of breath, or risk factors such as diabetes or high blood pressure. Thanks to advancements in cardiac care in India, monitoring heart health has become easier and more accessible. It’s important to be aware of the warning signs of a heart attack to understand why these tests are crucial. 

What Is a Cardiac Stress Test?

A cardiac stress test is a test that allows doctors to monitor the functioning of your heart when it is forced to pump more effectively, usually by exercise or medicines. It can show whether enough blood is reaching your heart, whether your heart rhythm is healthy or whether you may require additional cardiac attention.

These tests are safe, quick, and usually done as outpatient procedures. Your age, previous medical history and current health condition determine the type of test that your doctor would suggest. Stress test result charts by age can help give you a better understanding of what’s normal at different ages.

6 Types of Cardiac Stress Tests

Cardiac stress testing may give you important information about how your heart responds to stress, which you could wonder about at any time. The tests are intended to be safe, simple, and empowering, and the choice you and your physician can make towards your heart health. Here are the types of cardiac stress tests that you must know about:

1. Exercise Stress Test (Treadmill Test)

This cardiac stress test is the most typical one. You will move on a treadmill, and your heart rate, systolic and diastolic pressure, and ECG will be examined. It helps to understand how your heart reacts when you exercise.

•       It is often used to identify the presence of coronary artery disease.
•       It is not invasive and usually takes about 15 minutes.

2. Stress Echocardiogram

This is a combination of an exercise test with an ultrasound of your heart. The doctor will take pictures of your heart before and after exercise to examine how well it pumps blood.

•       It is helpful in detecting the problems related to blood circulation and the movement of the heart musculature.
•       Recommended when the ECG is used on its own, fails to provide clear results.

3. Nuclear Stress Test

During this test, a small portion of radioactive dye is injected into your body using a harmless needle. A special camera follows the dye to see how the blood flows to your heart both with and without stress. So, what is involved in a cardiac stress test? This test may involve walking on a treadmill or using medication to simulate exercise, and these are:

•       Quite precise in identifying obstructions
•       Used when other stress tests provide ambiguous results. 

It’s helpful to understand what chest pain may feel like to distinguish between minor discomfort and serious warning signs.

4. Pharmacologic Stress Test

In case you are unable to exercise because of a medical condition, your heart is made to behave as though you are exercising through medication. The response of your heart is then measured.

•       Elderly or physically limited patients are suitable
•       Medication is used to mimic the physical workout

5. Cardiopulmonary Exercise Test (CPET)

This diagnostic test for heart patients is used to gauge the efficiency of your heart and lungs when they have to work together during exercise. When you exercise, you blow into a mouthpiece.

•       Assists in identifying the causes of unexplained breathlessness
•       Monitors carbon dioxide and oxygen when in motion

6. Stress MRI

The newer advanced test is an MRI imaging of the heart during a stressful situation. It provides clear, detailed images and works well even in challenging cases.

•       It’s non-invasive, but still not available in every facility
•       Possibly advisable in cases of uncommon or hard-to-method noticeable trimmings

What is a Good Cardiac Stress Test Score?

Your score will depend on your age and how fit you are. A good outcome is generally based on obtaining 85 per cent or above of your estimated top heart rates without even unusual ECG readings. According to a study in the Indian Heart Journal, stress tests are a key tool in detecting coronary artery disease in Indian patients, and the accuracy of the diagnostic method is enhanced by the use of imaging methods. That’s the main goal of a cardiac stress test.

What is a Bad Heart Rate During a Stress Test?

If your heart rate doesn’t increase as expected — or drops suddenly — it may signal a problem. Irregular rhythms or chest pains could also be an indication that another test or treatment is required. Chest pain or breathlessness during exertion shouldn’t be ignored. In emergencies, contact our emergency cardiac care team right away for timely support. In such cases, understanding the heart attack vs cardiac arrest difference becomes crucial for appropriate intervention. Nevertheless, a good part of those consequences can be dealt with effectively through life changes and early treatment, including maintaining an Indian heart-healthy diet and regular exercise.
