Case Reports
Electrocardiogram (ECG) changes and cardiac biomarker abnormalities among two marathon runners.
Marathon running has surged in popularity in the last quarter century. A small percentage of marathon runners develop increases of myocardial-specific markers with exercise, sometimes in the diagnostic range for acute myocardial infarction. A spectrum of abnormal electrocardiogram (ECG) patterns has also been described. ⋯ Previously asymptomatic individuals under extreme physical exertion may be at risk for myocardial stress and myocyte injury. Abnormal ECG patterns in patients under these conditions may not correlate with structural cardiovascular disease.

Barium appendicitis (BA) is a rarely seen entity with fewer than 30 reports in the literature. However, it is a known complication of barium imaging. ⋯ BA is a rare entity and the pathogenesis is unclear. Shorter intervals between barium study and presentation with appendicitis usually correlate with fewer complications.
