Estrogen has been known to prevent heart disease in premenopausal women by increasing effectiveness and number of LDL cholesterol receptrors on liver.
This chemical is also a strong antioxidant. It also reduces the number of cholesterol and fat carrying lipoprotiens chylomicrons that are formed in intestinal cells and transport cholesterol from cells to the liver. It can also slow or stop atherosclerosis.
A high fiber diet has been shown to reduce risk of heart disease. Psyllium also traps undesirable bile acids within the intestine, which means the liver must pull more LDLs in from the bloodstream to compensate. It also prevents cholesterol and fat from entering the intestinal cells by expanding the unstirred water layer, which increases the barrier for diffusion of fat and cholesterol across the intestinal wall.

It may be even more effective at lowering cholesterol when compared to oats due to the higher beta-glucan content.
