Understanding Cardiac Screening: Procedures, Benefits, and Recommendations

Did you know, 1905 people die in the US due to heart disease every day? Heart problems are a major concern in the US. However, with early diagnosis, most heart problems are treatable and manageable. Learn the main cardiac screening tests that are used to diagnose heart diseases in this article. Get a consultation with the best cardiologists in Brooklyn.


Cardiac screening tests

Heart screening tests are the best way to prevent or manage severe heart conditions like coronary artery disease. Here are some of the common tests that are used for cardiac screening:


  1. Electrocardiography:

This test is used to measure the electrical activity of the heart and records information about heart rate and rhythm. In this procedure, doctors use small or stick electrodes which are applied to your chest and attached with a special machine called an ECG machine. The electrodes send the information into the machine which records the heart’s electrical activity and provides information about your heart rate and rhythm.


  1. Exercise cardiac stress test:

In this test, doctors attach electrodes to your chest and ask you to run on a treadmill or pedal a stationary bike by constantly increasing your speed. This test can show how your heart responds to physical stress. Additionally, doctors also check your heart rate, rhythm, and blood pressure. If the test shows enough blood flow to your heart when stressed, then your heart is healthy. If you’re not able to exercise, then the doctor may give you medication that makes your heart beat harder and faster.


  1. Echocardiography:

In this test, the doctor uses an ultrasound machine to see moving images of your heart by passing sound waves through your body. This helps to detect problems with the pumping function of your heart by assessing your heart valves. Sometimes, they order stress echocardiography tests, where they take ultrasound tests before or after you have exercised or taken certain medication to see how the heart responds to stress.


  1. Nuclear stress test:

In this test, doctors inject a small amount of radioactive dye into your bloodstream, where it can travel to your heart. Then the doctor uses an imaging machine to take pictures while you’re at rest and after exercise to check the blood flow through your heart.


  1. Cardiac CT scan for calcium scoring:

In this test, the doctor puts you under a CT scanner with electrodes attached to your chest to record your heart’s electrical activity. This can produce images to detect calcium in your coronary arteries. Calcium findings indicate that much-calcified plaque buildup happens in the coronary arteries. This can increase the risk of coronary arteries getting narrowed (known as stenosis).


  1. Coronary CT angiography (CTA):

In this procedure, doctors ask you to lie under a CT scanner with electrodes attached to your chest after injection of a contrast dye into your bloodstream to create 3-dimensional images of your coronary arteries to check the exact location and extent of plaque buildup (both calcified and noncalcified). It also helps to check the blockage and narrowing of your coronary arteries.


  1. Coronary catheter angiography:

In this test, doctors use a small tube or catheter inserted into your groin or arm which passes through an artery to your heart. Through the catheter, the doctor injected a contrast dye to see any blockage or narrowing of the coronary arteries with the help of X-rays to capture images of your heart.


  1. Myocardial perfusion imaging (MPI):

In this test, doctors inject a small amount of radioactive material into your vein. The material can accumulate in your heart muscle and with the help of a small camera, doctors take pictures of your heart while you are at rest and exercise. Doctors use this test to check the blood flow through the coronary arteries to the heart muscle.


If your diagnosis shows a heart disease, your doctor may recommend medical treatment along with lifestyle changes to manage your conditions and prevent complications.



Cardiac screening tests are recommended when you experience symptoms like high blood pressure, fatigue, heart palpitations, etc. that indicate heart problems. Tests like electrocardiography, nuclear stress test, coronary CT angiography, etc. allow doctors to examine the main blood vessels in the heart and how the heart performs under physical stress. If a heart problem is detected, doctors prescribe treatment based on the underlying cause of the heart problem and may recommend lifestyle changes to improve your heart health.
