What does elevated troponin T levels mean?

When a person has significantly elevated troponin levels and, in particular, a rise and/or fall in the results from a series of tests done over several hours, then it is likely that the person has had a heart attack or some other form of damage to the heart.

What should troponin T levels be?

Having a result between 0.04 and 0.39 ng/ml often indicates a problem with the heart. However, a very small number of healthy people have higher than average levels of troponin. So, if the result is in this range, a doctor may check for other symptoms and order further tests before making a diagnosis.

Can stress cause high troponin levels?

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.

How do you treat high troponin levels?

If troponin levels are high (elevated above normal) and the EKG indicates an acute heart attack, you may have cardiac intervention such as a catheterization with angioplasty and possibly stents, or an evaluation for coronary artery bypass graft (CABG) surgery may be required.

Can anxiety cause troponin levels to rise?

Stress-induced cardiomyopathy mimics symptoms of acute myocardial infarction with acute chest pain, electrocardiographic changes and a transient increase in the level of cardiac biomarkers including troponins.

How accurate is troponin test?

The assay has high precision at low concentrations and can detect cTnI in 96.8% of healthy individuals.

Can dehydration cause elevated troponin?

Exercise-induced dehydration, hemoconcentration, and altered acid-base balance were also reported to be associated with this increased membrane permeability. Troponin elevation was not found to be associated with any functional impairment using either echocardiography or cardiac magnetic resonance imaging.

What causes false high troponin?

False values can occur due to interferences from heterophile antibodies or human autoantibodies that mimic troponin, that minimic troponin, by linking the capture antibody to detection antibody. Dilution of the samples often fails to cause changes in the values.

Which troponin is more accurate?

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.

Do troponin levels return normal?

Troponin levels typically start to elevate in the circulation within 2 to 3 hours of the onset of chest pain. The levels will continue to rise at that time until a peak is reached, generally between 12 and 48 hours. The troponin level will then begin to fall over the next 4 to 10 days down to a normal level.

How long do troponin levels stay high?

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.

Why is troponin better than troponin 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 can cause elevated troponin?

“Anything that severely stresses or damages the heart can cause an elevation of troponin, though not usually to the extent seen in a heart attack. “Heart failure, trauma, pulmonary embolism and even kidney failure can lead to elevated troponin levels.” So can a body-wide infection (sepsis).

What can increase troponin levels?

Elevated troponin causes. Though a rise in troponin levels are often an indication of a heart attack, there are a number of other reasons why levels could elevate. Other factors that could contribute to high troponin levels include: intense exercise. burns. extensive infection, like sepsis.

What does High troponin level mean?

High troponin levels can indicate a problem with the heart. The heart releases troponin into the blood following an injury, such as a heart attack. Very high troponin levels usually mean that a person has recently had a heart attack. The medical term for this attack is myocardial infarction.

What is the normal range for troponin levels?

Troponin is an enzyme or protein that is used for the evaluation of heart injury. The normal troponin level is 0.00 to 0.04 ng/ml.
