Carotid artery disease (CAD) means the major blood vessels in your neck are narrowed or becoming blocked. These 2 major blood vessels are called the carotid arteries. They supply your brain with blood. The narrow or blocked blood vessels increase your risk for a stroke. CAD is also called carotid artery stenosis.

Drugs used to treat this and similar conditions

Medicines:

You may need any of the following:

• Cholesterol medicine lowers your cholesterol level.
• Blood pressure medicine lowers or helps control your blood pressure.
• Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell your provider if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits.

Warning signs of a stroke:

The words BE FAST can help you remember and recognize warning signs of a stroke:

• B = Balance: Sudden loss of balance
• E = Eyes: Loss of vision in one or both eyes
• F = Face: Face droops on one side
• A = Arms: Arm drops when both arms are raised
• S = Speech: Speech is slurred or sounds different
• T = Time: Time to get help immediately

Prevent a stroke:

• Do not smoke, and avoid secondhand smoke. Nicotine and other chemicals in cigarettes and cigars increase your risk for a stroke. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your provider before you use these products.
• Eat a variety of healthy foods. Healthy foods include fruit, vegetables, whole-grain breads, low-fat dairy products, chicken, and fish. Choose fish that are high in omega-3 fatty acids, such as salmon and fresh tuna. Ask your provider for more information on a heart healthy diet and the DASH eating plan.
• Limit sodium (salt). Sodium may increase your blood pressure. Add less table salt to your foods. Read food labels and choose foods that are low in sodium. Your provider may suggest you follow a low sodium diet.
• Reach or maintain a healthy weight. Extra weight makes your heart work harder. Ask your provider what a healthy weight is for you. Your provider can help you create a safe weight-loss plan, if needed. Even a weight loss of 10% of extra body weight can help your heart function better.
• Exercise regularly. Exercise helps improve heart function and can help you manage your weight. Exercise can also help lower your cholesterol and blood sugar levels. Try to get at least 30 minutes of exercise 5 times each week. Try to be physically active every day. This may include walking, riding a bicycle, or swimming. Your provider can help you create an exercise plan that works best for you.
• Limit alcohol. Alcohol can increase your blood pressure and triglyceride levels. A drink of alcohol is 12 ounces of beer, 5 ounces of wine, or 1½ ounces of liquor.
