PAD is a collateral circulation problem — EECP builds new vessels

Peripheral artery disease causes leg pain, claudication, and tissue ischemia due to arterial narrowing. EECP stimulates angiogenesis and collateral vessel formation, improving blood flow without surgery.

Mechanism of Action

How EECP works for PAD / PVD (Peripheral Artery & Vascular Disease)

STEP 01
Diastolic augmentation

Cuffs inflate in diastole, driving a wave of blood retrograde through the aorta — increasing coronary perfusion pressure and delivering oxygen-rich blood to ischemic tissue.

STEP 02
Nitric oxide release

Increased shear stress on the endothelium triggers release of nitric oxide — the body's master vasodilator — improving vessel tone and reducing inflammation.

STEP 03
Angiogenesis

Repeated sessions stimulate VEGF and other growth factors, promoting the formation of new collateral blood vessels in ischemic tissue.

STEP 04
Systemic vascular improvement

Endothelial function improves throughout the body — not just at the heart — producing benefits in peripheral, cerebral, and microvascular circulation.
