Stress echocardiography has a number of advantages over exercise elect
rocardiography. It has superior sensitivity and specificity as it dete
cts wall motion abnormalities, an earlier and more specific marker for
myocardial ischaemia than ST segment depression. It can also localise
ischaemia and identify hibernating myocardium. Compared with radionuc
lide imaging, stress echocardiography has similar accuracy but is chea
per and does not involve exposure to ionising radiation. The disadvant
age of stress echocardiograph is that it requires expertise and specia
list experience of at least 100 studies. Current research aims at impr
oving objective methods of analysing results. The technique is justifi
ably being adopted throughout the UK.
