In Reply: Dr Petrella asserts that most persons aged 75 years and older can satisfactorily complete an exercise stress test. However, Hollenberg et al1 found that 68% of a large sample of community-living persons aged 75 years and older did not attempt or were excluded from performing the exercise stress test for physical or medical reasons. Among the remaining subgroup, only 26% achieved maximal exercise effort, despite a protocol that increased the work rate gradually, in 2-minute increments. Interestingly, the study by Petrella et al2 actually supports these conclusions. Among another representative sample of community-living persons aged 75 years and older, less than 20% were able to complete an exercise stress test.3
