This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!
Summary: People with heart disease who experience mental stress induced-ischemia tend to have higher levels of troponin — a protein whose presence in the blood that is a sign of recent damage to the heart muscle — all the time, independently of whether they are experiencing stress or chest pain at that moment.
Can stress cause elevated troponin?
Stress-induced cardiomyopathy mimics symptoms of acute myocardial infarction with acute chest pain, electrocardiographic changes and a transient increase in the level of cardiac biomarkers including troponins.
What can cause falsely elevated troponin?
This may be observed in several well-known situations including pulmonary embolism, pericarditis, myocarditis, coronary vasospasm, sepsis, congestive heart failure, supraventricular tachycardia with hemodynamic compromise, re-nal insufficiency, and prolonged strenuous endurance exercise.
Can dehydration cause elevated troponin?
Exercise-induced dehydration, hemoconcentration, and altered acid-base balance were also reported to be associated with this increased membrane permeability. Troponin elevation was not found to be associated with any functional impairment using either echocardiography or cardiac magnetic resonance imaging.
Can you have elevated troponin without having a heart attack?
Elevated cardiac troponin, a diagnostic marker of damage to the heart, may occur even if a patient has not had a heart attack, according to a study published in JACC: Basic to Translational Science.

How do you treat high troponin levels?
If troponin levels are high (elevated above normal) and the EKG indicates an acute heart attack, you may have cardiac intervention such as a catheterization with angioplasty and possibly stents, or an evaluation for coronary artery bypass graft (CABG) surgery may be required.
How can I get my troponin levels down?
To prevent the risk of further heart attacks, a doctor will usually recommend lifestyle changes, such as quitting smoking, losing weight, getting more exercise, and eating a more healthful diet. Treatments of other causes of high troponin levels may be different from treatments of a heart attack.
How long do troponin levels stay high?
Levels of troponin can become elevated in the blood within 3 to 6 hours after heart injury and may remain elevated for 10 to 14 days. Increased troponin levels are not be used by themselves to diagnose or rule out a heart attack. A physical exam, clinical history, and ECG are also important.
What drugs cause high troponin levels?
Cocaine has also been associated with cardiotoxic effects caused by vasoconstriction and increased cardiac sympathetic stimulation. These effects may be demonstrated by troponin rise . Colchicine, medication commonly used for the treatment of gout flare has been associated with troponin elevation.
How quickly do troponin levels drop?
Troponin levels typically start to elevate in the circulation within 2 to 3 hours of the onset of chest pain. The levels will continue to rise at that time until a peak is reached, generally between 12 and 48 hours. The troponin level will then begin to fall over the next 4 to 10 days down to a normal level.
Why would my troponin levels be elevated?
When heart muscles become damaged, troponin is sent into the bloodstream. As heart damage increases, greater amounts of troponin are released in the blood. High levels of troponin in the blood may mean you are having or recently had a heart attack. A heart attack happens when blood flow to the heart gets blocked.
Do troponin levels fluctuate?
Throughout his stay, fluctuations in measured troponin levels correlated strongly with fluctuations in hemoglobin levels. Several investigations confirmed false elevated troponin levels secondary to heterophile antibody interference.
Is elevated troponin always bad?
However, the presence of increased troponin is one marker of severity of underlying illness and as such has been used to identify people at higher risk of bad outcomes. This is felt to be related to severe cardiac strain related to the underlying illness or possibly to microvascular disease in the heart.
Can stress cause elevated heart enzymes?
Severe stress on the heart can damage its muscle. When that happens, your heart releases certain enzymes — a kind of protein — into your blood. After a heart attack, the level of these enzymes can get pretty high.
What’s the highest troponin level?
However, the value of >95 000 ng/L reported in this case, overwhelmed the upper limit of normal, suggesting severe myocardial damage. This level of troponin was the highest value obtained since we commenced the use of this assay (Beckman-Coulter Access Accu TNI).
What is a good troponin level?
For example, the normal range for troponin I is between 0 and 0.04 ng/mL but for high-sensitivity cardiac troponin (hs-cTn) normal values are below 14ng/L. Other types of heart injury may cause a rise in troponin levels.
How do you check troponin levels?
Troponin levels are measured with a standard blood test. A healthcare provider will take a sample of your blood from a vein in your arm or hand. You can expect mild pain and maybe light bleeding.
How often should troponin levels be checked?
Serial measurement of cardiac troponins after the initial level is obtained at presentation, 3 to 6 hours after symptom onset, is recommended. If initial levels are negative, additional measurements beyond the 6-hour mark should be obtained.
How accurate is troponin test?
Abstract. We sought to evaluate diagnostic accuracy of a high-sensitivity cardiac troponin I (hs-cTnI) assay for acute coronary syndromes (ACS) in the emergency department (ED). The assay has high precision at low concentrations and can detect cTnI in 96.8% of healthy individuals.
How often do you repeat troponin levels?
Concerning troponins can be repeated as often as every 2-3 hours. When assessing the acuity of injury, think about troponin trends in terms of changes in log units (i.e. 0.05 to 0.07 vs 0.05 to 5).
How much troponin rise is significant?
A hs Troponin T above 30 ng/l is more likely to be consistent with an MI. The higher the hs Troponin T level the more likely the patient has had an MI although stable hs Troponin levels marginally above 30 ng/l do occur with alternative pathology.
What does a troponin level of 12 mean?
Cardiac troponin levels are normally so low they cannot be detected with most blood tests. Having normal troponin levels 12 hours after chest pain has started means a heart attack is unlikely. A normal value range may vary slightly among different laboratories.
What are the 3 cardiac enzymes?
Cardiac enzymes ― also known as cardiac biomarkers ― include myoglobin, troponin and creatine kinase.
What does a troponin level of 10 mean?
The level of troponin that indicates a heart attack is the level above the reference range. For example if the normal reference range is listed as 0.00 – 0.40. Then 0.41 is technically positive although very weakly so, and 10 is very positive.
Can Exercise raise troponin levels?
Regular exercise is healthy and reduces the risk of cardiovascular disease. Nevertheless, it appears that prolonged and/or intensive exercise can lead to an increase in cardiac biomarkers in the blood, such as the regulatory protein troponin.
