The troponin is not found or very less in blood when you are normal and doesn’t have any heart related medical condition. A normal troponin level in blood is below 0.04 ng/mL. If the troponin level is higher than 0.40 ng/mL, this could be an indication of heart injury.
If your test level is between 0.05 to 0.39, you will have to repeat the test. Even if there is a mild increase in the level of troponin, it may mean there has been some heart damage. It is better to get your heart tested. Very high levels of troponin indicate the patient has suffered a heart attack.
When you have suffered a heart attack, the level of troponin starts elevating and becomes high within the first 6 hours of the attack. It remains elevated even for one or two weeks.
An increase in troponin levels can be due to other conditions:
- Coronary artery spasm
- Blockage of a lung artery by a blood clot, fat, or tumour cells (pulmonary embolism)
- Inflammation of the heart muscle usually due to a virus (myocarditis)
- Trauma that injures the heart, such as a car accident
- Long-term kidney disease
- Congestive heart failure
- Weakening of the heart muscle (cardiomyopathy)
- Abnormally fast heartbeat
- Prolonged exercise (for example, due to marathons or triathlons)
- High blood pressure in lung arteries (pulmonary hypertension)
It can also be due to the result of any medical procedures
- Open heart surgery
- Cardiac angioplasty/stenting
- Radiofrequency ablation of the heart
- Heart defibrillation or electrical cardioversion (purposeful shocking of the heart by medical personnel to correct an abnormal heart rhythm)
