Answer

Partial ileal bypass is a surgical procedure that uses shortening of the ileum to lower circulating cholesterol levels. It has been used since the 1960s for the treatment of hyperlipidemia. Chelation therapy, using intravenous ethylenediaminetetraacetic acid and/or hydrogen peroxide, is a controversial treatment for atherosclerosis. Plethysmography/extracorporeal counterpulsation may reduce angina and improve exercise tolerance in patients with CAD, possibly by improving vascular endothelial function.
