What does slightly elevated troponin mean?
Even a slight increase in the troponin level will often mean there has been some damage to the heart. Very high levels of troponin are a sign that a heart attack has occurred. Most patients who have had a heart attack have increased troponin levels within 6 hours.
Can troponin be elevated without heart attack?
The elevated troponins in the absence of myocardial ischemia are rare; however, it can be seen in conditions such as myocarditis, pulmonary embolism, acute heart failure, sepsis and septic shock, hypovolemia, renal failure, atrial fibrillation and cardiac contusion [2, 3].
Can elevated troponin be normal?
If high levels of troponin are found in one or more tests over time, it probably means you had a heart attack. Other reasons for higher than normal troponin levels include: Congestive heart failure. Kidney disease.
What is a significant troponin elevation?
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.
Is 0.010 troponin level normal?
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.
Why do I have an elevated troponin level?
Elevated Troponin Causes. In this article,I talked extensively about the reasons that troponin levels might be elevated.
What can elevate troponin levels?
Troponin can be temporally elevated in some situations, a finding that is related to increased membrane permeability.53The myocardial depressing factors released in sepsis and other inflammatory conditions cause troponin to be fragmented into low molecular weight particles in situ.
What might explain my elevated troponin level?
Obstructive coronary artery disease (CAD)
What are the signs of elevated troponin levels?
– chest pain – shortness of breath – a rapid heart rate – lightheadedness – fatigue
