Energy drinks give you wings but also an abnormal exercise test

This is the case of a 53-year-old man with known coronary artery disease who underwent two exercise treadmill tests (ETT). The first test, which yielded an abnormal result, was undertaken shortly after he had drunk two cans of Red Bull, a popular energy drink (ED). A second ETT was undertaken 1 week later by the same team without EDs on board and the test result was normal. This case suggests that drinking EDs prior to an ETT could lead to a false positive result and should be discouraged prior to exercise testing.
