What is troponin?

What is troponin?

Heart blood test: Troponin is a type of blood enzyme test that detects heart muscle breakdown. The troponin level can go up with heart attacks (myocardial infarctions). ...Read more

Troponin (Definition)

Troponin is an enzyme found in heart muscle, which is involved in the muscle fiber's ability to contract. It is extremely specific to heart muscle, and hence if levels are elevated in the blood, it points very confidently toward heart muscle damage as a cause of patient's symptoms. In fact, it is the test that is used to definitively ...Read more

What does "troponins were cycled" mean?

What does "troponins were cycled" mean?

Cycling: Not sure what you mean or where you got that terminology. We often do serial troponin exams over a time period to see whether the level is rising/falling; one might call that cycling. Physiologically there is a cycle of troponin binding during heart contraction so not sure what you mean. ...Read more

What is normal troponin level?

Depends: Depends on the assay being used...Need to check against reference range listed next to the result as this varies & there are different kinds of troponins. ...Read more

What does a troponin level test?

What does a troponin level test?

Damaged heart tissue: Cardiac markers including ckmb and troponins measure damage to the heart muscle which occurs in a heart attack - the damaged/dying muscle will leak these into the serum which can be measured as blood tests. They start off "negative" - in the reference range - and then 4-6 hrs after the start of the heart attack they begin to rise - will eventually peak and over several days return to normal. ...Read more

What else can troponin detect apart from a mi?

What else can troponin detect apart from a mi?

Many: There are many reasons for troponin to be elevated. For example lung clot , stroke and other brain lesions can cause this. Also troponin could be elevated without any specific reason i.e. False-positive this is more common in kidney feeling. ...Read more

What is the troponin test done for?

What is the troponin test done for?

Check for heart atta: Troponin is measured to check for a heart attack, as troponin t is a specific protein that only the heart makes. If it is in the blood it means some heart muscle was damaged, which could be because of a heart attack. ...Read more

What would cause high troponin levels?

What would cause high troponin levels?

Damaged heart muscle: If heart muscle cells r damaged, troponin will leak into the blood + levels will rise. However, the muscle damage may be caused by several diseases, not the least of which is coronary artery disease (c article via link below 4 details) http://www.Ncbi.Nlm.Nih.Gov/pmc/articles/pmc1860726/ bottom line? Troponin levels r a sensitive + specific indicator of heart muscle damage from any cause. Dr mike. ...Read more

What is cardiac-specific troponin t?

What is cardiac-specific troponin t?

A biomarker: Measurement of troponin t is used to help make the diagnosis of myocardial infarction (heart attack). The chemical leaks from damaged heart muscle and confirms injury to the heart. A new assay called highly sensitive troponin is now available and is 10 times more sensitive and increases the speed and accuracy of the diagnosis. If the result is negative 3 hours after chest pain, mi is unlikely. ...Read more

What is cardiac specific troponin t?

What is cardiac specific troponin t?

Cardiac enzyme: Troponin t is an enzyme in heart muscle cells that is specific to heart muscle so the term "cardiac specific troponin t" is redundant. Normally, almost all of the troponin t we own is inside of the heart muscle cells with almost none (an immeasurably small amount) is in our blood. When the heart is injured, some troponin leaks into the blood where it becomes measurable. ...Read more

What could <0.10 Troponin I signify? I was released from the hospital with this level after ekg (w/pvc) normal sinus rhythm,CT,Chest X-ray

What could <0.10 Troponin I signify? I was released from the hospital with this level after ekg (w/pvc) normal sinus rhythm,CT,Chest X-ray

Troponin: Chest pain related tests include checking the blood for release of heart muscle cell Troponin and CPK. Release of these substances occur when the heart is damaged by decreased blood flow from a blockage in the pipe supplying blood to the heart, direct trauma or from inflammation of the muscle, etc. The rate of release and amount determines the significance of the release to guide management. ...Read more

What is considered a high troponin level?

What is considered a high troponin level?

This can vary: Both troponin i and troponin t assays are used to test the blood for evidence of damage to the heart muscle. The normal range for troponin i is higher than the normal range for troponin t. In a given laboratory, the normal ranges may differ from that in another laboratory, depending upon the assay system used. Each laboratory generally publishes normal ranges for the particular assay it uses. ...Read more

What would cause a LOW troponin level of 0.015?

What would cause a LOW troponin level of 0.015?

HEART OF THE MATTER!: TROPONIN is a chemical found in some tissues, but most commonly used because it is a unique to cardiac muscle. When ELEVATED it can indicated recent injury to the heart. LOW TROPONIN is a GOOD THING! ...Read more

What does low level of troponin I mean?

What does low level of troponin I mean?

Normal finding: Troponin i is elevated due to injury to heart muscle and is used to help diagnose heart attacks as well as stratify risk in patients with chest pain. A low or unmeasurable troponin is a normal finding but does not guarantee a lack of heart issues. ...Read more
