Exercise stress

There are two main techniques to achieve exercise stress – (a) semi-supine bicycle exercise or (b) a conventional treadmill test. Semi-supine bicycle is more sensitive than post-treadmill exercise (27). There are limited data to indicate similar sensitivity of SE during treadmill exercise to semi-supine bicycle but this is technically difficult (28). The aim of exercise SE is to achieve both the maximum target heart rate which is calculated (220 – age), although sensitivity of the test does not appear to fall providing imaging is performed above 85% of the maximum heart rate and maximal exercise. If a patient fails to achieve a minimum of 85% maximum heart rate, the rate of cardiovascular events in those who do not achieve their target but have normal images is higher than those who do achieve their target and have normal images (29). Similarly, failure to achieve a reasonable absolute level of exercise (defined as <7 metabolic equivalents (METs) for men and <5 METs for women) is a predictor of subsequent cardiac events even if SE is normal (30).
