Lack of detection of myocardial injury during competitive races of 100 miles lasting 18 to 30 hours.
Competitors in an ultramarathon performed under extreme conditions did not demonstrate evidence of subclinical myocardial injury, as determined using cardiac troponin T as a marker. This finding refutes previous data and is likely due to utilization of an improved assay for cardiac troponin T that minimizes cross reactivity with skeletal muscle troponin T.
Evidence of myocardial injury during prolonged strenuous exercise.
These preliminary data suggest that extremely prolonged intense exercise may induce subclinical myocardial injury. Although questions of assay interference exist, the importance of this finding has prompted planning of a larger study using a methodologically more specific assay.

Hypocalcemia after therapeutic use of magnesium sulfate.
It is now recognized that magnesium plays an important role in calcium homeostasis. Although the effects of hypomagnesemia have been frequently reported, little has been written to suggest a clinically important role for hypermagnesemia. A case is reported in which severe hypocalcemia, with a low plasma parathyroid hormone (PTH) concentration, resulted from the therapeutic use of magnesium sulfate for toxemia of pregnancy. Following recovery, the parathyroid glands were shown to respond normally to a phosphate load. It is suggested that the hypermagnesemia directly suppressed PTH secretion, resulting in symptomatic hypocalcemia.
