  • Cardiac risk markers’ test analyses the risk of cardiovascular diseases

Cardiac risk markers are substances that are released by a damaged heart muscle. They include glucose, cholesterol, blood sugar level, uric acid and more. These cardiac markers are analyzed in a combination of blood tests as they help determine conditions like coronary artery disease, heart failure, stroke, and heart attack. Together these blood tests are called cardiac risk markers test. People with cardiac risk markers need to monitor their heart health so as to prevent further damage to the heart.

What is a cardiac risk markers test? 

A cardiac risk markers test refers to multiple blood tests that are done to analyze the risk of developing cardiovascular diseases like heart attack and stroke. It indicates cardiovascular risk as low, moderate, or high.

The test measures the level of cardiac biomarkers such as proteins, hormones, and enzymes in your blood. Here is a list of usual biomarkers considered in this test. 

  • Lipoprotein A 
  • Apolipoproteins 
  • Homocysteine 
  • cardiac troponin
  • Creatinine kinase (CK)
  • CK-MB
  • Myoglobin

When is a cardiac risk markers test done? 

Doctors may ask you to get a cardiac risk markers test if they diagnose the risk of a heart attack. The following symptoms of coronary artery blockage may also require you to undergo this test [1]: 

  • Sweating 
  • Nausea 
  • Vomiting 
  • Weakness
  • Clammy or pale skin
  • Fainting or dizziness
  • Irregular pulse rate
  • Extreme tiredness or fatigue
  • Chest pain or pressure in your chest 
  • Discomfort or pain in the neck, arms, shoulders, and jaw 
  • Chest pain that doesn’t heal even after taking rest or nitroglycerine

How is a cardiac risk markers test done? 

This test follows the same procedure as a blood test. A 3 mm to 10 mm blood sample is drawn from a vein in your arm using a needle. The technician in the lab will use a cotton or alcohol pad to clean your skin. Then a needle is injected in the vein. The blood is then gradually collected and saved in a container that is marked with your name. This sample is then sent for testing.

What do cardiac risk markers test results depict? 

Results are found in nanograms per milliliter (ng/mL). It is rare for those who are healthy and young to have any cardiac troponin, a protein that is released during any damage of the heart, in their blood. Troponin I levels are usually less than 0.12 ng/mL whereas levels of Troponin T are less than 0.01 ng/mL. 

Although the normal results may differ, a cardiac troponin level of more than the 99th percentile of the reference range indicates a heart attack or heart muscle damage. The following factors affect your test results: 

  • Age 
  • Gender 
  • medical history 
  • Testing method 

Your doctor may be better able to read out your results to you and explain what it means for your health. 

Are there any major risks involved in the cardiac risk markers test? 

The blood test to determine cardiac test involves the use of needles that are safe in most cases. The temporary side effects or risks may include the following: 

  • Bleeding 
  • Bruising
  • Infection
  • Sore skin
  • Lightheadedness
  • Sting or pain at the site of injection

What are the drawbacks of the cardiac risk markers test? 

It takes a substantial amount of time to determine the levels of cardiac markers when analyzing your blood in a lab. This is a reason the test is not helpful in certain cases, such as diagnosing an acute heart attack. In such cases, clinical presentation and ECG results will be much beneficial.
