The carotid endarterectomy removes plaque directly from blocked arteries and there is no alternative way to mechanically remove plaque. However, there are alternative ways to prevent the buildup of plaque and thus help to prevent stroke or heart attack....

Certain vitamin deficiencies in older people are known to promote high levels of homocysteine, an amino acid that contributes to atherosclerosis, putting people at greater risk for stroke or heart attack. Certain nutritional supplements have been shown to reduce homocysteine levels.

Nutritional supplements and alternative therapies that are sometimes recommended to help reduce risks and promote good vascular health include:

• Folic acid, which helps lower homocysteine levels and increases the oxygen-carrying capacity of red blood cells.
• Vitamins B₆ and B₁₂, which help lower homocycteine levels; B6 is also a mild diuretic and helps to balance fluids in the body.
• Antioxidant vitamins C and E, which work together to promote healthy blood vessels and improve circulation.
• Angelica, an herb that contains coumadin, a recognized anticoagulant, which may help to prevent clot formation in the blood (blood thinner).
• Essential fatty acids, which help reduce blood pressure and cholesterol, and maintain elasticity of blood vessels.
• Chelation therapy, which can be used to break up plaque and improve circulation.
