The magnitude of hyperemic flow response was measured after transient forearm occlusion.

We investigated the relationship between FMD and hyperemic flow with adverse clinical outcomes in HF patients.

All 14 patients with abnormal distal hyperemic flow-velocity values had corresponding reversible 99mTc-sestamibi tomographic defects.

Multiple studies with this approach reported diminished hyperemic flow responses in patients without hemodynamically significant coronary stenoses but with coronary risk factors.

Reduced hyperemic flow, but not FMD, was associated with an increased risk of death or cardiac hospitalization after controlling for traditional risk factors.
