Supports stress echocardiography for ischemia detection in chronic disease; leaves open standardization to minimize operator variability.
Structured PICO
Does stress echocardiography accurately detect myocardial ischemia and provide prognostic information compared to other non-invasive tests?
P
Population
Patients undergoing evaluation for myocardial ischemia, chronic coronary disease, post-myocardial infarction, or pre-operative assessment
E
Exposure
Stress echocardiography
C
Comparator
Exercise ECG and stress myocardial perfusion scintigraphy
O
Outcome
Detection of significant coronary stenoses and prognostic evaluationsurrogate
Stress echocardiography is a versatile, accurate, and powerful prognostic tool for detecting myocardial ischemia, though limited by subjective interpretation and submaximal exercise.
Limitations
- Image quality problems
- Test interpretation remains subjective
- Need to induce ischaemia limits accuracy in patients who exercise submaximally or are on antianginal treatment
- Test interpretation is subjective
- Abnormal wall motion is the only mainstream marker of ischemia
- Limited accuracy in patients who exercise submaximally or are on antianginal treatment
