Normal Troponin Levels After Heart Attack
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
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?
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
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
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
Went to er for heart attack symptoms. Did a troponin t test. It was normal. They didn't do a series of troponin tests. Safe to say I didn't have a mi?
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
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.
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
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?
Possibility of heart attack with normal: EKG, troponin, nuclear stress, cardiac MRI, echo, calcium score? I have chest / left arm pain. Need cath/CTA?
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. Find a good doc ...Read more
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??
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
BNP 148 to 305. Troponin 1 - 2.004 to 1.184. Does this mean patient had a mild heart attack? Patient has 3 tripple vessel disease.
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
I had a heart attack last week. The ECG was clear. Angiogram showed healthy arteries with no blockages. Bloodtest=0.40 of troponin. What caused it?
Chest pain, SOB, nausea, no appetite over a month. Been to ER many times. EKG and troponin always fine. Heart attack ruled out? What else could it be?
I went to ER for chest pain, racing heart, dizzy. EKG / troponin / chest xray negative heart attack. Still hurts 5 days later. Possibly still heart?
No appetite, SOB, PVCs, rapid HR. EKG, troponin, d dimer, and chest xray good. Echo mon, tilt test in 2 wks. Need stress test? Heart attack ruled out?
Yes. Anxiety: Sounds like your heart is fine but you may be stressed out over something. Calm down and do a thorough self analysis to unravel whatever is making you tic! ...Read more
My triponin levels were at 5.0 in the ER and remained up overnite. No damage shown on ekg, is a mild heart attack possible? Clogged secondary arterie
Can a severe panic attack elevate troponin levels (0.12) in an otherwise healthy 34 year old male with no personal/family history of heart disease?
Yes, it can.: Hi, thanks for the question. There are many different situations that can place enough stress on the heart to elevate troponins in the blood, including panic attacks and emotional stress. I would suggest you visit your doctor for an EKG and to schedule a stress test to help evaluate the vessels that supply your heart with blood. And if you experience chest pain, don't hesitate to go to your ER! ...Read more
If someone dies of heart failure, ANY TYPE of heart failure, will there be a rise in troponin levels?
Sometimes in ER my troponin levels are high sometimes not but they say there is no heart prob. I never know when to go to er?
Troponin levels: Troponin levels may be elevated in normal individuals. As your heart is ok I wouldn't worry. ...Read more
Few things: Troponin is a marker of several heart disorder including heart attack. Other cardiac conditions such as inflammation of the heart muscle, inflammation of the sac around the heart (pericardoum) also can cause troponin release in the blood. Troponin is increased in cardiac contusion, defibrillation of the heart and some cardiac procedures. It is positive up to 10-14 days after the injury. ...Read more
Sometimes I go to ER with chest pains and my troponin levels are up sometimes not but they always say my heart is fine?
Unclear: I would be concerned about troponin levels going up with chest pain (how high?) but if you already had a cardiac cath, and if you were told your coronary arteries are normal that is very good news. Even without blockages, some patients have issues with cocaine, arterial spasms, clots, uncontrolled hypertension, or other conditions but only your doc can give you a diagnosis from a complete history. ...Read more
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
