Characteristics of Stress Ischemic Endpoints
| Perfusion | Wall motion |
|---|---|
| Initial event in the ischemic cascade | Follows induced perfusion abnormality |
| Does not require ischemia | Requires ischemia |
| Specific indicator of ischemia or ischemic potential | Nonspecific indicator of ischemia |
| Not significantly affected by loading conditions | Affected by loading conditions |
| Not significantly affected by resting wall motion abnormalities | Affected by resting wall motion abnormalities |
| Not generally affected by conduction abnormalities | Affected by conduction abnormalities |
