Atherosclerosis in Seniors

Watch this video about:Atherosclerosis

Atherosclerosis often occurs with aging. As you grow older, plaque buildup narrows your arteries and makes them stiffer. These changes make it harder for blood to flow through them.

Clots may form in these narrowed arteries and block blood flow. Pieces of plaque can also break off and move to smaller blood vessels, blocking them.

These blockages starve tissues of blood and oxygen. This can result in damage or tissue death. It is a common cause of heart attack and stroke.

High blood cholesterol levels can cause hardening of the arteries at a younger age.

For many people, high cholesterol levels are due to or worsened by a diet that is too high in saturated fats and trans fats.

Other factors that can contribute to hardening of the arteries include:

• Diabetes
• Family history of hardening of the arteries
• High blood pressure
• Lack of exercise
• Being overweight or obese
• Smoking

Atherosclerosis does not cause symptoms until blood flow to part of the body becomes slowed or blocked.

If the arteries supplying the heart become narrow, blood flow can slow down or stop. This can cause chest pain (stable angina or unstable angina), shortness of breath, and other symptoms.

Narrowed or blocked arteries may also cause problems in the intestines, kidneys, legs, and brain.

A health care provider will perform a physical exam and listen to the heart and lungs with a stethoscope. Atherosclerosis can create a whooshing or blowing sound (“bruit”) over an artery.

Most people age 18 or older should have their blood pressure checked every year. More frequent measurement may be needed for those with a history of high blood pressure readings or those with risk factors for high blood pressure. . Ask your provider what schedule is best for you.

Cholesterol testing is recommended in all adults. The major national guidelines differ on the suggested age to start testing.

• Screening should begin at age 20 for both men and women.
• Repeat testing is not needed for five years for most adults with normal cholesterol levels.
• Repeat testing may be needed if lifestyle changes occur, such as large increase in weight or a change in diet.
• More frequent testing is needed for adults with a history of high cholesterol, diabetes, kidney problems, heart disease, stroke, and other conditions

A number of imaging tests may be used to see how well blood moves through your arteries. Check with your provider to see if any of these are recommended for you.

• Doppler tests that use ultrasound or sound waves
• Magnetic resonance arteriography (MRA), a special type of MRI scan
• Special CT scans called CT angiography
• Arteriograms or angiography that use x-rays and contrast material (sometimes called “dye”) to see the path of blood flow inside the arteries

Lifestyle changes will reduce your risk for atherosclerosis. Things you can do include:

• Quit smoking: This is the single most important change you can make to reduce your risk for heart disease and stroke.
• Avoid fatty foods: Eat well-balanced meals that are low in fat and cholesterol. Include several daily servings of fruits and vegetables. Adding fish to your diet at least twice a week may be helpful. However, do not eat fried fish.
• Limit how much alcohol you drink: Recommended limits are one drink a day for women, two a day for men.
• Get regular physical activity: Exercise with moderate intensity (such as brisk walking) 5 days a week for 30 minutes a day if you are at a healthy weight. For weight loss, exercise for 60 to 90 minutes a day. Talk to your provider before starting a new exercise plan, especially if you have been diagnosed with heart disease or you have ever had a heart attack.

If your blood pressure is high, it is important for you to lower it and keep it under control.

The goal of treatment is to reduce your blood pressure so that you have a lower risk of health problems caused by high blood pressure. You and your provider should set a blood pressure goal for you.

• Do not stop or change high blood pressure medicines without talking to your provider.

Your provider may want you to take medicine for abnormal cholesterol levels or for high blood pressure if lifestyle changes do not get you to your goals for these. This will depend on:

• Your age
• The medicines you take
• Your risk of side effects from possible medicines
• Whether you have heart disease or other blood flow problems
• Whether you smoke or are overweight
• Whether you have diabetes or other heart disease risk factors
• Whether you have any other medical problems, such as kidney disease

Your provider may suggest taking aspirin or another medicine to help prevent blood clots from forming in your arteries. These medicines are called antiplatelet drugs. DO NOT take aspirin without first talking to your provider.

Losing weight if you are overweight and reducing blood sugar if you have diabetes or pre-diabetes can help reduce the risk of developing atherosclerosis.

Atherosclerosis cannot be reversed once it has occurred. However, lifestyle changes and treating high cholesterol levels can prevent or slow the process from becoming worse. This can help reduce the chances of having a heart attack and stroke as a result of atherosclerosis.

In some cases, the plaque is part of a process that causes a weakening of the wall of an artery. This can lead to a bulge in an artery called an aneurysm. Aneurysms can break open (rupture). This causes bleeding that can be life threatening.
