To the Editor: Dr Gill and colleagues1 stated that few older persons are capable of achieving maximal effort on a stress test, defined as a respiratory exchange ratio of 1.10 or greater, but it is unclear if the authors suggest that patients undergoing stress testing should attempt to achieve maximal effort. It is also important to differentiate between stress testing for screening purposes and maximal exercise testing to determine functional capacity.
