Overview

Risk factors for carotid artery stenosis are almost similar to those for cerebrovascular accident (CVA), coronary heart disease (ACS) and peripheral vascular disease (PVD). Common risk factors include hypertension, smoking, advanced age and abnormal cholesterol levels including lowered HDL levels in the blood.

Risk Factors

Risk factors for carotid artery stenosis include:

• Age - older age (>65 yrs) is associated with increased risk
• Hypertension - blood pressure more than 140/90 mm Hg is a risk factor for carotid artery stenosis and should ideally be maintained below that cut off level
• Smoking
• Abnormal cholesterol levels - Low HDL and high LDL cholesterol
• Diabetes
• Obesity - increases the risk of hypertension as well as increases the development of atherosclerosis
• Insulin resistance
• Sedentary lifestyle
• Positive family history for atherosclerosis, coronary heart disease and carotid artery stenosis
• High dietary saturated fatty acids
