| High risk |
- Severe resting LV dysfunction (EF <35%)
|
- Extensive new rest wall motion abnormality (≥5 of 16 segments of LV)
|
- Moderate-sized rest wall motion abnormality (3 to 4 segments) with remote ischemia
|
- Echocardiographic wall motion abnormality (>3 segments) developing at low ischemic threshold (dobutamine dose ≤10 micrograms/kg/minute or a heart rate <120 beats/minute)
|
- Stress echocardiographic evidence of extensive ischemia (4 to 5 segments of LV) or ischemia in multiple coronary territories or peak wall motion score >1.7
|
- Severe exercise LV dysfunction (exercise EF <35%) or decrease in global LV contractility from rest to stress due to ischemia
|
- Dilatation of the LV cavity with stress with associated ischemic wall motion abnormalities
|
| Intermediate risk |
- Mild to moderate resting LV dysfunction (EF 35 to 49%) with no ischemia
|
- Moderate-sized resting wall motion abnormality (3 to 4 segments) with no ischemia
|
- Limited resting wall motion abnormality (≤2 segments) with limited (≤2 segments) peri-infarction ischemia
|
- Normal resting wall motion with limited ischemia (≤2 segments) at high stress level
|
| Low risk |
- Normal resting wall motion with no ischemia
|
- Limited resting wall motion abnormality (≤2 segments) with no ischemia
