exercise stress echocardiography
Indications:
- suspected of coronary artery disease
- recommended when baseline ECG is abnormal* or when information on the area of myocardium at risk is needed
- can can identify asymptomatic patients at high risk after revascularization
- these patients do not necessarily benefit from repeat revascularization [2]
* left-bundle branch block acceptable for exercise stress echocardiography [3]
Advantages:
1) exercise data are acquired along with imaging for wall motion abnormalities that indicate ischemia
2) entire study is complete in < 1 hour
Disadvantages:
- image quality is suboptimal in some patients but can be improved by use of echo-contrast
Notes:
- a wearable device consisting of an 8 uM stretchable strip of sensors applied to the chest to obtain continuous cardiac ultrasound images can facilitate obtaining ultrasound images during exercise including real-time estimates of stroke volume, cardiac output, ejection fraction, wall-motion abnormalities, & chamber size [4]
