5 Medical Tests That Can Help Detect Heart Problems

5 Medical Tests That Can Help Detect Heart Problems

Heart issues can be severe and can affect your life. Here are five medical tests that can tell you if you have a heart issue and why they’re essential.

Key points

  • Heart disease is the leading cause of death in the United States.
  • Early detection and treatment of heart disease can save lives.
  • Several medical tests can help detect heart problems.
  • Some of the most common medical tests for heart disease include electrocardiograms (EKGs), echocardiograms, stress tests, cardiac catheterizations, and blood tests.
  • If you have any risk factors for heart disease, talk to your doctor about which medical tests are proper for you.


Heart problems are illnesses that affect your heart and how it pumps blood around your body. Various things, like genetics, lifestyle, infection, or injury, can cause them.

If you have a heart problem, getting it checked out early and getting the proper treatment is essential.

Otherwise, you could end up having a heart attack, having a stroke, or even dying from a sudden heart attack.

5 Medical Tests That Can Help Detect Heart Problems

One of the best ways to find out if you have a heart problem is to do a medical test. A medical examination is a procedure that measures or records different parts of your heart.

A medical test can help doctors determine if you have heart problems, how serious they are, and what kind of treatment you should take.

Some medical tests, like a catheter or needle, don’t involve putting anything in your body, so they’re usually non-invasive.

This article will discuss five medical tests that can help detect heart problems and why they are essential. These tests are:

  1. Electrocardiogram (ECG)
  2. Echocardiogram
  3. Stress test
  4. Coronary angiogram
  5. Cardiac MRI

Electrocardiogram (ECG)

An ECG is a test that looks at your heart’s electrical activity. It shows how your heart is beating and how much blood your heart is pumping. It’s not invasive, so you don’t need to worry about it.

An ECG can help detect:

  • Abnormal heart rhythms (arrhythmias)
  • Heart damage due to a previous or ongoing heart attack
  • Enlargement or thickening of the heart muscle (hypertrophy)
  • Reduced blood flow to the heart muscle (ischemia)
  • Congenital heart defects

Electrocardiograms (ECGs) are performed by placing electrodes (small adhesive strips) on the chest, hands, and feet.

The strips are connected to an ECG machine that reads the electrical pulses from your heart. Each ECG lasts about 10 minutes, and the procedure is painless.


Echocardiograms are non-invasive tests that use ultrasonic waves to take pictures of your heart. The pictures show what your heart looks like, how it works, and how it and its valves move.

Echocardiograms can help you figure out what’s wrong with your heart.

  • Abnormalities in the size, shape, or function of the heart chambers or valves
  • Problems with the pumping ability of the heart (ejection fraction)
  • Clots or tumors in the heart
  • Infections or inflammation of the heart (endocarditis or myocarditis)
  • Congenital heart defects

An echocardiogram is done by placing a transducer on the chest. The transducer emits sound waves that bounce off the heart and are picked up by the same device.

The sound waves are converted into images on a monitor. The echocardiogram takes about 30 minutes and is painless.

Stress test

It’s a test that shows how your heart responds to physical stress. It can be triggered by exercise or medication that causes your heart to beat faster or faster.

A stress test can help detect:

  • Reduced blood flow to the heart muscle (ischemia) due to narrowed or blocked arteries (coronary artery disease)
  • Abnormal heart rhythms (arrhythmias) triggered by exercise or medication
  • Problems with the blood pressure or oxygen levels during exercise or medication
  • Symptoms such as chest pain, shortness of breath, dizziness, or fainting during exercise or medication

A stress test involves monitoring your ECG, blood pressure, and oxygen levels while exercising on a treadmill bike or taking medication through an IV line. The test lasts about one hour and can cause some discomfort.

Coronary angiogram

It’s an X-ray showing how blood flows in your heart’s arteries. Your heart’s arteries are the blood vessels that give your heart the oxygen it needs.

A coronary angiogram can help detect:

  • Narrowing or blockage of the coronary arteries (coronary artery disease) that can cause chest pain (angina) or heart attack
  • The location and extent of the narrowing or blockage of the coronary arteries
  • The suitability of the coronary arteries for treatment options such as angioplasty, stenting, or bypass surgery

A coronary angiogram is done by inserting a thin, flexible tube (catheter) into a blood vessel in the groin or arm and advancing it to the heart.

A contrast dye is injected through the catheter, and X-rays are taken as the paint flows through the coronary arteries.

The coronary angiogram takes about an hour and may cause discomfort or complications such as bleeding, infection, or allergic reaction.

Cardiac MRI

A cardiac MRI is a non-invasive test that uses magnetic fields and radio waves to create detailed images of the heart and its tissues.

A cardiac MRI can help detect:

  • Damage or scarring of the heart muscle due to a previous or ongoing heart attack, inflammation, or infection
  • Abnormalities in the structure or function of the heart chambers, valves, or vessels
  • Tumors, clots, or masses in the heart
  • Congenital heart defects

A cardiac MRI is done by lying inside a large tube-like machine that creates a magnetic field around the body.

The device emits radio waves that interact with the atoms in the body and produce signals that are converted into images on a computer.

A contrast dye may be injected to enhance the photos. The cardiac MRI takes about an hour and is painless.

Frequently Asked Questions

What are the symptoms of heart problems?

Some common symptoms of heart problems are chest pain, shortness of breath, palpitations, fatigue, swelling in the legs or ankles, dizziness, fainting, or sweating.

What are the risk factors for heart problems?

Some risk factors for heart problems are high blood pressure, high cholesterol, diabetes, smoking, obesity, physical inactivity, family history, age, gender, or stress.

How can I prevent heart problems?

You can prevent heart problems by adopting a healthy lifestyle that includes eating a balanced diet, exercising regularly, quitting smoking, managing stress, controlling your blood pressure, cholesterol, and diabetes, and taking medications as prescribed by your doctor.

How are heart problems treated?

Heart problems are treated depending on their type and severity. Some treatment options are medications, lifestyle changes, surgery, devices such as pacemakers or defibrillators, or procedures such as angioplasty, stenting, or bypass surgery.

When should I see a doctor for heart problems?

You should see a doctor for heart problems if you have any symptoms or risk factors for heart problems. You should also see a doctor if you have a family history of heart problems or have been diagnosed with a heart problem before.


Heart problems can be severe and can even lead to death. If you think you have a heart problem, medical tests can help you determine how serious it is and what kind of treatment you should take.

Electrocardiograms, Echocardiograms, Stress Tests, Coronary Angiograms, and Magnetic Resonance Imaging (MRI) can help determine if you have a heart problem.

They can tell you about how the heart works, its structure, how it works, how much blood it’s pumping, and how much tissue it’s making.

If you have any symptoms or risk factors for a heart problem, tell your doctor about having these tests done.
