A method and system for creating shear stress and endothelial mechanotransduction through neuromuscular stimulation of the muscle pump. Chronic application a minimum of 30 days triggers the autocrine and paracrine processes which elevates production of vasoactive substances including nitric oxide, prostacyclin, superoxide dismutase, thrombomodulin, glutathion, Krupple-like factor 2 and many others. Chronic application also promotes angiogenesis and development of collateral circulation. This is a cost-effective, non-invasive, drug-free therapy to treat vascular dysfunction and ameliorate or reverse its effects on cardiovascular health.
