Troponin levels and a heart attack

What is the connection between troponin levels and a heart attack? Elevated Troponin levels in the bloodstream are a marker for damage to the heart, research has shown that a Troponin blood test could point to earlier treatment for patients and much improved outcomes for those that have had a heart attack.

A heart attack is everyone’s worst nightmare because heart disease kills more people in the world than all of the other major diseases combined, a heart attack can be life changing and for those lucky enough to survive the sooner a diagnosis is made the sooner treatment can begin and blood flow to the heart can be restored and the damage done can repair.

What happens when the heart muscle is damaged?

When the heart muscle is damaged a specific Troponin blood test can measure the levels of Troponin in the blood helping your health professional to understand the amount and type of cardiac specific Troponin levels and what the implications are for your health, this test is also known as cardiac troponin (CTN), cardiac specific troponion I (CTnl) , cardiac troponion T(cTnT) troponion T.

Even the smallest increase in Troponin levels could mean that there has been some damage done to the heart although this isn’t always the case, a very high Troponin level is a sign that a heart attack has happened and this usually happens within six hours, mostly everyone that has suffered a heart attack has elevated Troponin levels that remain in the blood for up to two weeks.

What Is Troponin?

Troponin is a form of protein that is found in cardiac and skeletal muscle and they are associated with muscle contraction, many labs in the USA use a high sensitivity Troponin test since the FDA approved them back in 2017, if the heart muscle is damaged Troponin is released into the blood, so any patient that presents with heart attack symptoms or chest pain will have their Troponin levels measured.

Why would you need a Troponin blood test?

There are a number of reasons why you would need a Troponin blood test that include:

  • Dizziness
  • Fatigue
  • Nausea
  • Vomiting
  • Chest pain or discomfort in that area
  • Other pain in your neck, jaw, arm or back
  • Heavy sweating

Following your first Troponin blood test more than likely you will be tested two or more times over a twenty-four-hour period to check for any changes in levels, a phlebotomist will collect a small blood sample from a vein in your arm, you don’t need to fast, if you want to have the Troponin blood test done privately that service is provided by True Health Labs to find out more go to their website here.

Are there risks?

There are no risks associated with a Troponin blood test you may have a small amount of pain or bruising at the point of where the needle is inserted but they symptoms don’t last for long.

What do your results mean?

When normal Troponin levels are present in the bloodstream a Troponion blood test is the only test that will be able to locate them, should your results show normal levels after chest pain symptoms have started it’s highly unlikely that you have had a heart attack, however if small levels of the protein are found it could be a marker that your heart is damaged in some way.

Higher levels of Troponin in your blood found in more than one test is a definitive marker for a significant heart attack, there are other conditions that could also cause higher levels such as kidney disease, a blood clot on your lungs or congestive heart failure.

Is the Troponin test accurate?

Troponin blood tests for a heart attack have evolved and developed over the years, nowadays a high-sensitivity test is the most commonly used test trusted blood test that checks for very low Troponin levels to detect and diagnose heart attacks very quickly, the high-sensitivity test can also be used to rule out any damage to the heart muscle.

What happens if your levels are high?

When you get your tests results and if they are elevated above normal you may be sent for an EKG to check for an acute heart attack which could lead to cardiac intervention, a procedure called angioplasty and the possibility of stenting will be considered, a CAT scan or stress tests may also be in the mix.

Troponin is a very specific protein associated with the heart muscle so if you have had a heart attack the level of Troponin will start to rise within 2-4 hours following the onset of the heart attack, they will stay high for about two weeks afterwards, a Troponin blood test can also be use to test for stable angina, cardiomyopathy, congestive heart failure or obstructive coronary artery disease, all of these conditions relate to heart damage.

  1. Troponin levels and a heart attack is a superb article on this most important topic. You may have saved many lives if u have this knowledge. There are a number of reasons why we could need a Troponin blood test that are Dizziness, Fatigue, Nausea, vomiting, Chest pain or discomfort in that area, other pain in your neck, jaw, arm, or back, and heavy sweating.

    I have literally no medical knowledge which is why I keep reading such posts to understand how our body works. 
    Thanks for this good article.


  2. This is my first time hearing of Troponin and I really learnt a great deal about it from reading your article ‘Troponin levels and a heart attack’ so thank you for sharing this truly informative and insightful article. Troponin levels sound like a really serious issue, it’s nice to know a blood test can be carried out from the onset in order to prevent further complications. 

    • Hi Beesean,

      Elevated Troponin levels are a sign of a heart attack, the results of a blood test can help the doctor to diagnose and treat the condition.


  3. As we get older, our heart health is something that we worry more about, but I must say that this is the first time that I have read about a Troponin blood test. I wonder if one should have this test as a precautionary measure if you are over the age of 50 just to be safe, as one hears of so many people dropping dead of a heart attack, and they never had any symptoms.

    I think I am going to investigate this option further just for my own peace of mind in this regard.

    • Hi Michael,

      You are correct so many die unexpectedly from heart attacks and stroke, having a simple Troponin blood test can help with an early diagnosis and preventative measures.
