Myocardial Infarction (Definition)

Myocardial Infarction means some of the heart muscle dies because of insufficient oxygen supply. Most often this occurs because the coronary artery is blocked by plaque & clot. Other causes include tears in the artery wall, extremely high oxygen demand (eg, rapid arrhythmia, heart valve disorder, or severe systemic illness.) Prompt treatment can minimize heart damage & ...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

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

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

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

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

MI: ER evaluation of 'MI' symptoms includes clinical history, exam and appropriate lab tests. If there was low probability of MI given the situation, multiple troponins would not necessarily be needed ...Read more

Does having a troponin 1 of <0.02 and a normal ekg rule out a heart attack? Cardiac cath clean in 2011

Does having a troponin 1 of <0.02 and a normal ekg rule out a heart attack? Cardiac cath clean in 2011

Heart attack?: A normal electrocardiogram along with two or three negative troponin values should suffice to rule out a heart attack. This does not rule out the presence of heart disease, necessarily. But in a moment of chest pain, this combination should suffice to rule out a heart attack. ...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

Normal ekg, troponin, d dimer, and chest xray. Heart attack ruled out?

Normal ekg, troponin, d dimer, and chest xray. Heart attack ruled out?

Yes, but not: Heart disease. From the data you provided, myocardial infarction, (heart attack) can be ruled out, but not other heart diseases. Get clearance from your doctor to exercise and do it. Also - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more

ECG 12 leads: Normal sinus rhythm, Possible Left atrial enlargement, Inferior infarct, ACUTE MI / STEMI, Abnormal ECG When compared with ECG of 30-MAR-2015 ST elevation now present in Inferior leads. BUT troponins are ok. Is it heart attack?

ECG 12 leads: Normal sinus rhythm, Possible Left atrial enlargement, Inferior infarct, ACUTE MI / STEMI, Abnormal ECG When compared with ECG of 30-MAR-2015 ST elevation now present in Inferior leads. BUT troponins are ok. Is it heart attack?

Repeat EKG: Computer interpretation is often wrong, not surprisingly. If no chest pain and cardiac enzymes are normal-likely, it's not a heart attack. There are several other causes of ST segment elevation besides a heart attack. I would repeat EKG and have it interpret from your cardiologist. Good luck. ...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

Is one troponin t test within 7 hours of symptoms enough to rule out heart attack. It as neg but I'm still having symptoms. I read a series sb done.

NoEasyAnswerToThis: There are no hard & fast rules. Each case must be evaluated on its own. Yes, in certain circumstances one troponin 7 hours after onset of symptoms can rule out some heart damage;but not necessarily a'heart attack, ' per se. You can have a bad headache without having a stroke, right? Also depends on your personal story, family history, lifestyle, diet, activities, stress factors, smoking, drugs.

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

ARE there any blood tests such as troponin that remain elevated weeks to months or even years after a heart attack??

ARE there any blood tests such as troponin that remain elevated weeks to months or even years after a heart attack??

In general there are: No chemical markers that remain elevated more than about two weeks after an infarct. EKG changes do progress over a longer time course. There can be elevations of some markers that are unrelated to ongoing myocardial damage and can be confusing to less experienced health care providers. For instance, troponin can be elevated from CLL or pneumonia which are unrelated to the heart. ...Read more

Lab tests: Making statements purely on the basis of lab tests is fraught with risk. You should discuss this patient with the patient's Doc who has the complete picture to get a more informed answer from having more information about the patient. ...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
