Stress Echocardiography
Echocardiography performed at rest and during exercise or pharmacologic cardiovascular stress to detect inducible wall-motion abnormalities or valve-gradient changes.
Stress echocardiography combines echocardiographic imaging with a cardiovascular stressor (treadmill or bicycle exercise, or pharmacologic dobutamine / dipyridamole) to provoke and detect inducible regional wall-motion abnormalities indicative of coronary artery disease.
It is also used to assess inducible mitral regurgitation, low-flow / low-gradient aortic stenosis, and pulmonary hypertension under exertion, and to risk-stratify before non-cardiac surgery.
Reporting requires side-by-side comparison of rest and peak-stress wall motion across 16 or 17 LV segments. AI-assisted strain and EF support pre- and peak-stress interpretation by automating segmentation and providing a quantitative anchor alongside the visual read.
