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

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

Can you let me know how many hrs does heart enzymes stay elevated after a heart attack?

Up to 14 dsys: Troponin I or troponin t remains positive up to 14 days after a cardiac event. CPK and ckmb returns to normal after 72 hours. Troponin is a specific cardiac marker. However CPK is not it could be detected in the blood from skeletal muscle injury as well. ...Read more

Can it be a heart attack if I have symptoms of cheat pain back pain arm tingling etc. Enzymes and EKG were normal 2 days ago?

Can it be a heart attack if I have symptoms of cheat pain back pain arm tingling etc. Enzymes and EKG were normal 2 days ago?

Not likely: Myocardial infarction from blockage of a coronary artery is very rare in 27 yr old women. Other heart conditions or other medical causes are possible, but a detailed evaluation is needed to identify if any might be present. Though rare, one serious and sometimes overlooked cause of chest pain/arm tingling is pulmonary embolism - blood clot in the lung. See your doctor if symptoms recur. ...Read more

Ekg normal. Enzymes normal 2 days ago.. Yet having chest pains arm tingles lite sweating heart rate not below 78. Can it be a heart attack?

Heartattack unlikely: At age 27, with normal ECG and normal enzyme levels, a myocardial infarction (heart attack) is highly improbable. The first pains of coronary artery narrowing (called angina) typically occur with exertion and are relieved by rest. If left untreated, eventually anginal pain may start to occur even at rest. Most likely, your symptoms do not represent a heart attack. ...Read more

Modify risk factors: Normal ekg, echo, cardiac ct cardiac enzymes can be useful to rule out a heart attack. At age 32 however we are still capable of building plaque in our arteries. Plaque does not suddenly appear. It starts in young adolescent age. Modifying risk factors includes healthy diet full of lots of plant food. Small amts healthy fats, minimal animal foods, no processed foods and daily exercise&no smoking ...Read more

Low levels may reclassify the same patient as a low risk. ...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

Now there is a better and newer way to risk stratify you that incorporates many other (risk) factors like smoking, family history, etc, and can determine a more accurate cardiac risk for you, and help us docotors deterimne if medication would help decrease your risks.

No crystal ball...: We can't predict who will have a heart attack, not even based upon LDL (bad) cholesterol & triglycerides. All we can do is estimate risk using medical calculators. Back in the day, we used Framingham risk score (http://cvdrisk. Nhlbi. Nih. Gov/) but since 11/13 we use Pooled Cohort Risk (http://my. Americanheart.

Should I seek help from my cardiologist if I want to know my stroke and heart attack risk level?

Risk factors: A cardiologist or internist can help define your rsk profile by getting a history (family history, smoking, diabetes, hypertension, hyperlipidemia), and arranging for a fasting lipid level. In high risk settings additional risk can be found with a lipid NMR study assessing non traditional risk factors such as lipoprotein particle size. Other risk factors, plac, crp, homocysteine could help. ...Read more
