What are other reasons other than heart attack for increased level of troponin?

What are other reasons other than heart attack for increased level of troponin?

Any heart problem: Troponin is an enzyme released by damaged heart muscle. While the major cause is a heart attack, and large increases are usually due to this, almost any condition affecting the heart can cause small increases. Viral infections of the heart, pulmonary embolus or medial procedures such as angioplasty often result in increases of troponin. ...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

Which levels of troponin during a heart attack are worrisome?

Which levels of troponin during a heart attack are worrisome?

Varies: This can vary depending on the particular assay... There is a troponin t and troponin i ... Also this could vary and is calibrated for lab to lab. ...Read more

What are blood enzyme and troponin levels before, after, during a heart attack?

What are blood enzyme and troponin levels before, after, during a heart attack?

Normal,then elevated: 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

Would normal troponin 1, myoglobin, ck-mb & creatine kinease levels 100% rule out heart attack?

Would normal troponin 1, myoglobin, ck-mb & creatine kinease levels 100% rule out heart attack?

You have anxiety: You do not have heart troubles. The tests are negative because this is not your heart. Any good doctor can tell you this. You are carrying your stress in your chest muscles and not breathing well. Your heart is fine. ...Read more

Can troponin levels elevate due to stress, anxiety and such and cause chest pain but will not cause a heart attack?

Can troponin levels elevate due to stress, anxiety and such and cause chest pain but will not cause a heart attack?

No: Stress and anxiety do not typically raise troponin levels. Medical conditions such as severe high blood pressure, congestive heart failure, renal failure are associated with elevated levels of troponin. Elevated troponin is not the cause of heart attack, but can result from one. ...Read more

Why was my younger brother rushed to hospital for emergent heart catheterization after severe crushing chest pain. Didn't have heart attack BUT his troponin level was high? got discharged 2 days later.

Why was my younger brother rushed to hospital for emergent heart catheterization after severe crushing chest pain. Didn't have heart attack BUT his troponin level was high? got discharged 2 days later.

My understanding is: that if he had these symptoms and his serial troponins were high,then he by definition DID have a heart attack,despitewhat the catheterization showed. This would be spasm of the coronaries,not blockage. It is called Prinzmetal's angina and can cause a heart attack with clean coronaries ...Read more

Thrombosis rca at p/mortem. No heart attack.deceased died from sepsis complications.How possible to hav thrombosis? No H/Attack.troponin level normal?

Thrombosis rca at p/mortem. No heart attack.deceased died from sepsis complications.How possible to hav thrombosis? No H/Attack.troponin level normal?

DIC? Hypotensive?: Hi. Sepsis is awful as you know from this case. Sepsis is accompanied by hypotension (low blood pressure), poor organ perfusion, and often disseminated intravascular coagulation (DIC = initiation of clotting cascade). While sepsis is the killer, it's not hard to picture the low blood pressure, poor perfusion, and activated clotting pathway causing a thrombosis in the RCA right at time of death. ...Read more

How is troponin a sign of heart attack ?

How is  troponin a sign of heart attack ?

Muscle damage: When heart muscle is injured troponin leaks into the blood where it can be measured. Elevated levels typically indicate some damage to the heart. There can be false positive readings especially in patients with renal failure. ...Read more

How high does the troponin result be, to signal a heart attack?

How high does the troponin result be, to signal a heart attack?

It depends: In the proper setting with chest pain & abnormal electrocardiogram an elevated troponin (highly sensitive version) can indicate heart damage. However there are other possible explanations for an elevated level. These include congestive heart failure, pulmonary embolism (blood clot in the lungs) or kidney failure. The pattern of the elevation over time is also useful. ...Read more

Heart Attack (Definition)

Heart attack is a life-threatening condition in which the blood vessels that supply the heart becomes occluded and thus the heart itself is not longer receiving any blood flow. Without this blood flow, the heart muscle dies and cannot pump blood to the ...Read more
