1 When the gallstones travel out of the gallbladder into the bile ducts, they block the opening that drains bile and enzymes. The bile and enzymes back up into the pancreas and cause swelling.  Genetics may be a factor in some cases. Sometimes, the cause is not known.
An increased level of the cardiac protein isoform of troponin circulating in the blood has been shown to be a biomarker of heart disorders, the most important of which is myocardial infarction. Raised troponin levels indicate cardiac muscle cell death as the molecule is released into the blood upon injury to the heart.
Levels of troponin can become elevated in the blood within 3 or 4 hours after heart injury and may remain elevated for 10 to 14 days. In people with angina, an elevated troponin may indicate that their condition is worsening and they are at increased risk of a heart attack.roponin tests are primarily ordered to help diagnose a heart attack and rule out other conditions with similar signs and symptoms. Either a troponin I or troponin T test can be performed; usually a laboratory will offer one test or the other.
