What causes elevated troponin I levels?

Share on Pinterest Elevated troponin levels may result from sepsis, kidney failure, heart failure, or a traumatic injury to the heart. Very high levels of troponin typically indicate that a person has had a heart attack, which can occur if the blood supply to some of the heart muscle suddenly becomes blocked.

What is a critical troponin level?

Clinical Interpretation For troponin concentrations 0.40 ng/mL and higher, the underlying cardiac injury is usually a myocardial infarction. Troponin concentrations of 0.04-0.39 ng/mL require serial troponin measurements and clinical correlation to interpret, as further described in the guidelines.

Can troponin be elevated without 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.

What is the highest possible troponin level?

False positive troponin results are likely to occur when the true concentration lies close to the diagnostic threshold. However, the value of >95 000 ng/L reported in this case, overwhelmed the upper limit of normal, suggesting severe myocardial damage.

Do troponin levels rise with angina?

In people with angina, an elevated troponin may indicate that their condition is worsening and they are at increased risk of a heart attack.

What does a troponin level of 14 mean?

Thus, when the high-sensitivity cardiac troponin T test detects levels above 14 ng/l, heart damage or heart attack is likely.

Can anxiety cause high troponin levels?

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.

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.

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.
