You're more likely to have atherosclerosis if you're a woman with a waist larger than 35 inches or a man with a waist that's 40 inches or more. You need some fat to be healthy, but if you have too much of it, the lining of your arteries doesn't work as well as it should. That makes atherosclerosis more likely.

Atherosclerosis is thickening or hardening of the arteries caused by a buildup of plaque in the inner lining of an artery. Risk factors may include high cholesterol and triglyceride levels, high blood pressure, smoking, diabetes, obesity, physical activity, and eating saturated fats.

Full Answer

What is the main cause of atherosclerosis in arteries?

Atherosclerosis and cholesterol. These deposits are made up of cholesterol, fatty substances, cellular waste products, calcium and fibrin (a clotting material in the blood). As plaque builds up, the wall of the blood vessel thickens. This narrows the channel within the artery, which reduces blood flow.

What is atherosclerosis and how does it affect the heart?

Atherosclerosis (sometimes called “hardening” or “clogging” of the arteries) is the buildup of cholesterol, fatty cells and inflammatory deposits (called plaque) on the inner walls of the arteries that restrict blood flow to the heart. Atherosclerosis can affect the arteries in the heart, legs, brain,...

What increases my risk of atherosclerosis?

High blood pressure, high cholesterol, diabetes and other conditions can increase your risk. It’s important to get a checkup every year to catch and manage any related conditions. Healthy lifestyle choices, medications and surgical procedures can prevent complications of atherosclerosis.

Is atherosclerosis the same as arteriosclerosis?

Atherosclerosis is a type of arteriosclerosis, which is any hardening of the arteries. But the two terms are often used to mean the same thing. How can hardening of the arteries affect my body? Atherosclerosis may begin in childhood, and it gets worse over time.

Which arteries are more likely to develop atherosclerosis?

The most important sites for clinically significant atherosclerotic disease in humans are the coronary arteries, with progression to atherothrombotic events and subsequent myocardial infarction.

Why is coronary artery more prone to atherosclerosis?

The coronary arteries are, in fact, more prone to blockages than many other arteries in the human body. The main reason is that there is to-and-fro blood flow in the coronary arteries, as well as in the legs and the carotid arteries, two other regions prone to blockages.

Why does atherosclerosis happen in arteries and not in veins?

Your arteries are built to handle a lot of pressure going through them at once. This high pressure contributes to plaques. But your veins are a low-pressure system.

What factors increase the risk of atherosclerosis?

High blood pressure: Over time, high blood pressure can damage artery walls, allowing plaque to build up. Diabetes: High blood sugar can damage the inner layers of the arteries, causing plaque buildup. Metabolic syndrome: High levels of cholesterol and triglycerides in your blood increase your risk.

What are 3 causes that can lead to atherosclerosis?

Atherosclerosis is a hardening of your arteries caused by gradual plaque buildup. Risk factors include high cholesterol, high blood pressure, diabetes, smoking, obesity, lack of exercise and a diet high in saturated fat.

Where is atherosclerosis most common?

The most common locations for atherosclerosis are: Arteries in the heart, known as coronary atherosclerosis; Arteries that supply the legs, known as peripheral arterial disease (pad); Arteries that supply the brain, known as carotid artery disease.

Is atherosclerosis in veins or arteries?

Atherosclerosis, sometimes called "hardening of the arteries," occurs when fat, cholesterol, and other substances build up in the walls of arteries. These deposits are called plaques. Over time, these plaques can narrow or completely block the arteries and cause problems throughout the body.

Which artery is the most common to have blockage?

Although blockages can occur in other arteries leading to the heart, the LAD artery is where most blockages occur. The extent of the blockage can vary widely from 1% to 100%.

Why is atherosclerosis so common?

Atherosclerosis, which develops from fatty plaque buildup, is a common type of arteriosclerosis. Plaque often starts to build up during childhood and gets worse with age. Risk factors include unhealthy cholesterol levels, unhealthy lifestyle habits, and your genes.

Why is coronary artery disease so common?

A lack of exercise (sedentary lifestyle) is linked to coronary artery disease and some of its risk factors. A lot of stress. Emotional stress may damage the arteries and worsen other risk factors for coronary artery disease. Unhealthy diet.

Why does coronary artery disease limit?

Coronary artery disease (CAD) is a narrowing or blockage of your coronary arteries, usually due to plaque buildup. Your coronary arteries supply oxygen-rich blood to your heart. Plaque buildup in these arteries limits how much blood can reach your heart.

Does atherosclerosis only affect coronary arteries?

Atherosclerosis can affect most of the arteries in the body, including arteries in the heart, brain, arms, legs, pelvis, and kidneys. It has different names based on which arteries are affected. Coronary artery disease (CAD) is plaque buildup in the arteries of your heart.

Which artery is the most common to have blockage?

Although blockages can occur in other arteries leading to the heart, the LAD artery is where most blockages occur. The extent of the blockage can vary widely from 1% to 100%.

What are the causes of atherosclerosis in the aorta?

Elevated levels of cholesterol and triglycerides in the blood. High blood pressure. Cigarette smoking. Diabetes. Smoking plays a big role in the progression of atherosclerosis in the aorta (the body’s main artery), coronary arteries and arteries in the legs.

What is atherosclerosis?

What is atherosclerosis? Atherosclerosis is a type of arteriosclerosis. The American Heart Association explains how atherosclerosis starts, how atherosclerosis is affected by high cholesterol levels, high blood pressure and smoking, blood clots and thickened artery walls.

Why does plaque get worse as you age?

Atherosclerosis is a slow, lifelong progression of changes in the blood vessels that may start in childhood and get worse faster as you age. The cause of atherosclerosis isn’t completely known. Many scientists believe plaque begins when an artery’s inner lining (called the endothelium) becomes damaged.

What happens if a plaque is blocked?

In either case, the artery can be blocked, cutting off blood flow. If the blocked artery supplies the heart or brain, a heart attack or stroke occurs.

What is the pain of a chest that is reduced blood flow to the heart muscle?

Angina(ch est pain from reduced blood flow to the heart muscle)

Where does plaque develop?

Plaque may partially or totally block blood flow through large- or medium-sized arteries in the heart, brain, pelvis, legs, arms or kidneys. This can lead to conditions such as:

Can a blocked artery cut off blood flow?

In either case, the artery can be blocked, cutting off blood flow.

Why do arteries get plaque?

Many believe the condition begins because of damage to the endothelium, the artery’s inner lining. Smoking, high cholesterol, high blood pressure, high blood glucose and other factors may cause the damage. Plaque collects where the damage occurred. The material may then stimulate the body to produce more substances, which also collect. The arteries get progressively thicker, and blood flow decreases more and more.

When does atherosclerosis start?

Atherosclerosis may begin in childhood, and it gets worse over time.

What is the disease that occurs when plaque builds up inside the arteries?

Atherosclerosis is a disease that occurs when plaque builds up inside arteries. The arteries get hard and narrow, which can restrict blood flow and lead to blood clots, heart attack or stroke. Atherosclerosis may begin in childhood, and it gets worse over time. Lifestyle changes, medications and surgical procedures can help prevent complications.

What test is used to diagnose atherosclerosis?

Your healthcare provider may order tests to diagnose atherosclerosis and plan treatment, such as: Angiography, a test that uses special X-rays to locate and measure blockages. A contrast dye is injected into the arteries to help the blockages show up on the X-rays.

What is the blood vessel that delivers blood and oxygen to the rest of the body?

Arteries are blood vessels that deliver blood and oxygen from the heart to the rest of the body. Plaque is a sticky substance made of fat, cholesterol, calcium and other substances. As plaque builds up, the arteries become hard and narrow.

How to tell if you have atherosclerosis?

To determine whether you have atherosclerosis, a healthcare provider will start with: Family medical history. Personal medical history. Physical exam, listening with a stethoscope for weak or absent pulse or an abnormal sound in your arteries called bruit.

Can anyone have atherosclerosis?

Anyone can have atherosclerosis, but some people have a higher chance of developing it. Risk factors include:

What is the risk factor for atherosclerosis?

Increased levels of high-sensitivity C-reactive protein (CRP), which is a marker of inflammation. Family History. Even though it is not included in the Framingham Risk Score, family history is one of the biggest risk factors overall for atherosclerosis.

Why do arteries narrow?

Atherosclerosis occurs when your arteries narrow and become less flexible because cholesterol, fatty substances, cell waste products, calcium and fibrin—collectively called plaque—collect on their inner walls. The arteries respond to the buildup by becoming inflamed, causing scar tissue and other cells to form in the affected areas , ...

What happens when plaque collects on the inner walls of the arteries?

What Is It? Atherosclerosis occurs when your arteries narrow and become less flexible, which happens when plaque collects on the inner walls.

What causes rapid heartbeats?

Chest pain, dizziness and shortness of breath are symptoms of cardiac arrhythmias. Atherosclerosis is one cause of rapid or irregular heartbeat; however, it can also be caused by angina, valvular heart disease, blood clots, thyroid abnormalities, electrolyte imbalance or previous heart damage. Arrhythmias may be frequent or infrequent.

What is the most common form of peripheral arterial disease?

Atherosclerosis in the legs is the most common form of peripheral arterial disease (PAD) and can lead to intermittent claudication—severe pain, aching or cramping when walking, numbness, reduced circulation, and if left untreated, gangrene (death of tissue).

What is the term for the pain in the legs and legs that is caused by a reduced blood flow to the heart?

Similarly, when blood flow to the arteries in the legs is reduced, leg pain called claudication may result.

How many women over 55 have high cholesterol?

High cholesterol. More than half of women over age 55 need to lower their blood cholesterol, and a quarter of all American women have blood cholesterol levels high enough to pose a serious risk for coronary heart disease—a result of atherosclerosis.

What is the condition called when blood clots are in the legs?

When atherosclerotic plaque and blood clots reduce blood flow to the legs or, less often, to the arms, the condition is called peripheral artery disease (PAD). PAD makes walking painful and slows injury healing. In the worst cases, it can result in the loss of a toe, foot, or leg — or even death. Like coronary artery disease (CAD), PAD was once ...

Which race is more likely to develop PAD?

Ethnicity. African American women are twice as likely as Caucasian women to develop PAD.

Is atherosclerosis confined to chest?

This increasingly common disorder often goes undetected in women until serious problems arise. Older women are learning that cardiovascular disease isn't confined to the chest. Atherosclerosis, once known as "hardening of the arteries," is the disease process at the root of most cardiovascular problems. It affects not only the vessels that feed the ...
