Interpretation of exercise and pharmacologic stress echocardiography
| Nature of tissue | Resting function | Low dose | Peak/post-stress function |
|---|---|---|---|
| CAD, coronary artery disease; WMA, wall motion abnormalities (severe hypokinesis, akinesis, dyskinesis). | |||
| Normal | Normal | Normal | Hyperkinetic |
| Ischaemic | Normal | Normal (may worsen with severe CAD) | Worse than rest |
| Worse than adjacent segments | |||
| Tardokinesis (delayed contraction) | |||
| Viable, ischaemic | Rest WMA | Improvement at low dose | Reduction (compared with low dose) |
| Viable, non-ischaemic | Rest WMA | Improvement at low dose | Sustained improvement |
| Infarction | Rest WMA | No change | No change |
