Making Sense Of Heart Tests: A Guide To Choosing The Right One For Your Needs

Heart disease is a leading cause of death worldwide, and early detection and diagnosis are crucial in managing and preventing this condition. Many tests are available to assess heart health, but it can be difficult to know which test is right for you. This article has some of the most common heart tests and provides guidance on choosing the right test for your needs.

Blood Tests

Blood tests are often used to assess heart health by measuring levels of cholesterol, triglycerides, and other lipids in the blood. High levels of cholesterol and triglycerides are major risk factors for heart disease. Blood tests can also measure C-reactive protein levels (CRP), a marker of inflammation in the body. Inflammation is a contributing factor to heart disease.

Electrocardiogram (ECG or EKG)

An ECG is a non-invasive test that measures the heart's electrical activity. It can detect heart rhythm problems, such as atrial fibrillation, and show if the heart is enlarged or damaged. An ECG can also help detect a heart attack or other acute coronary syndrome.

Stress Tests

A stress test assesses how well the heart functions during physical activity. This test can show if there is a lack of blood flow to the heart, indicating the presence of narrowed or blocked coronary arteries. Stress tests can be performed on a treadmill or with a medication that simulates the effects of exercise on the heart.

Cardiac CT

Cardiac computed tomography (CT) is a non-invasive test that uses X-rays to create detailed images of the heart and its structures. It can detect narrowed or blocked coronary arteries and can also detect plaque in the coronary arteries. This test is typically done in people with symptoms of heart disease or those at high risk of developing heart disease. Cardiac CT scan vs angiogram; what's the difference? An angiogram involves putting a catheter into the heart through the groin or wrist, while a cardiac CT scan is non-invasive.

Cardiac MRI

Cardiac magnetic resonance imaging (MRI) is a non-invasive test that uses a magnetic field and radio waves to create detailed images of the heart and its structures. It can detect problems with the heart's valves, such as leaky or narrowed valves, and show if the heart is enlarged or damaged. Cardiac MRI is particularly useful for evaluating the heart's function and detecting heart muscle damage.


An echocardiogram, also known as an ultrasound of the heart, is a non-invasive test that uses sound waves to create a detailed picture of the heart and its structures. An echocardiogram is a painless and safe test with no known risks or side effects. It is also useful in detecting problems that other tests may not see. This test can be used to monitor the effectiveness of treatment for heart disease or to see how well the heart functions after surgery.

Key Takeaway

When choosing a heart test, it's important to consider your individual risk factors for heart disease and any symptoms you may be experiencing. If you have a family history of heart disease or other risk factors, such as high blood pressure or high cholesterol, your doctor may recommend a blood test or an ECG. If you are experiencing symptoms such as chest pain or shortness of breath, your doctor may recommend a stress test or an echocardiogram. Any test chosen is usually at the discretion of your doctor.
