Cardiac troponin I appears to be a more specific marker of risk of composite cardiovascular disease and coronary heart disease, whereas cardiac troponin T is more strongly associated with risk of non–cardiovascular disease death.

Is it troponin 1 or I?
Troponin I is a cardiac and skeletal muscle protein family. It is a part of the troponin protein complex, where it binds to actin in thin myofilaments to hold the actin-tropomyosin complex in place. Troponin I prevents myosin from binding to actin in relaxed muscle.
What does a troponin level of 1 mean?
Very high levels of troponin are a sign that a heart attack has occurred. Most patients who have had a heart attack have increased troponin levels within 6 hours. After 12 hours, almost everyone who has had a heart attack will have raised levels. Troponin levels may remain high for 1 to 2 weeks after a heart attack.
What is Trop I test?
A troponin test measures the level of troponin in your blood. Troponin is a type of protein found in the muscles of your heart. Troponin isn't normally found in the blood. When heart muscles become damaged, troponin is sent into the bloodstream.
What is a normal troponin T level?
The normal range for troponin is between 0 and 0.4 ng/mL. Other types of heart injury may cause a rise in troponin levels.
What does a troponin level of 14 mean?
Thus, when the high-sensitivity cardiac troponin T test detects levels above 14 ng/l, heart damage or heart attack is likely.
Which is more sensitive troponin I or T?
Results: We found that (1) troponin I is a better cardiac marker than CK-MB for myocardial infarction because it is equally sensitive yet more specific for myocardial injury; (2) troponin T is a relatively poorer cardiac marker than CK-MB because it is less sensitive and less specific for myocardial injury; and (3) ...
What level of troponin indicates heart attack?
Laboratories measure troponin in nanograms per milliliter of blood (ng/ml). The University of Washington's Department of Laboratory Medicine provides the following ranges for troponin I levels: Normal range: below 0.04 ng/ml. Probable heart attack: above 0.40 ng/ml.
How high can a troponin level go?
Troponin levels can elevate within 3-4 hours after the heart has been damaged and can remain high for up to 14 days. Troponin levels are measured in nanograms per milliliter. Normal levels fall below the 99th percentile in the blood test.
How accurate is troponin test?
The two tests accurately ruled out heart attack in 30% of all chest pain presentations, but more than a third of people who didn't have a heart attack also tested positive. Only around a quarter of people with raised troponin have had a heart attack.
What if TROP T is positive?
The hs-troponin test may also be positive in people with stable angina and even in people with no symptoms. When it is elevated in these individuals, it indicates an increased risk of future heart events such as heart attacks.
What is Trop T test negative?
A negative test result refers to a normal test, where troponin is not detected in the blood. Some doctors also consider a normal troponin test to put a patient in a lower risk category for any serious cardiac events within the following few weeks.
Can anxiety cause troponin levels to rise?
Summary: People with heart disease who experience mental stress induced-ischemia tend to have higher levels of troponin -- a protein whose presence in the blood that is a sign of recent damage to the heart muscle -- all the time, independently of whether they are experiencing stress or chest pain at that moment.
