False Positive Troponin I Rendering Two Admissions for “Recurrent Acute Myopericarditis”

Electrocardiographic Changes and False-Positive Troponin I in a Patient with Acute Cholecystitis

Cardiac troponins are the most sensitive and specific serum markers of myocardial cell injury, but they can also arise without apparent cardiac injury. Besides, acute cholecystitis may be associated with nonspecific ST-T wave changes in electrocardiography (ECG). The signs and symptoms of gallbladder and heart disease may overlap, which can make diagnosis difficult. We describe the case of a 75...

False-negative immunoassay results for cardiac troponin I probably due to circulating troponin I autoantibodies.

A false positive case of cardiac troponin I: which diagnostic approach?

The pain was minimal but constant and unaffected by exertion or rest. She had no associated diaphoresis, nausea, or vomiting. The patient did not smoke and did not have hypertension, diabetes, or a family history of cardiac disease. Her low-...
