Is coronary artery disease the same as atherosclerosis

Atherosclerosis is a common condition that develops when a sticky substance called plaque builds up inside your arteries. Disease linked to atherosclerosis is the leading cause of death in the United States. About half of Americans between ages 45 and 84 have atherosclerosis and don’t know it.

Atherosclerosis develops slowly as cholesterol, fat, blood cells and other substances in your blood form plaque. When the plaque builds up, it causes your arteries to narrow. This reduces the supply of oxygen-rich blood to tissues of vital organs in the body.

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 yourheart.
  • Peripheral artery disease (PAD) most often is plaque buildup inthearteries of the legs, but it can also build up in your arms or pelvis.
  • Carotid artery disease is plaque buildup in the neck arteries. It reduces blood flow to the brain.
  • Renal artery stenosis is plaque buildup in the arteries that supply blood to your kidneys.
  • Vertebral artery disease is atherosclerosis in the arteries that supply blood to the back of the brain. This area of the brain controls body functions that are needed to keep you alive. Read more about disorders affecting blood supply to the back of the brain.
  • Mesenteric artery Ischemia is plaque buildup in the arteries that supply theintestines with blood. Learn more about plaque buildup in the mesenteric arteries.

Reduced blood flow can lead to symptoms such as angina. If a plaque bursts, a blood clot may form that may block the artery completely or travel to other parts of the body. Blockages, either complete or incomplete, can cause complications, including heart attack, stroke, vascular dementia, erectile dysfunction, or limb loss. Atherosclerosis can cause death and disability.

Confused about terms?
Atherosclerosis is not the same as arteriosclerosis, which refers to “hardening of the arteries,” which means the arteries thicken and lose flexibility. Arteriosclerosis has several different causes. 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.

The good news is that most people can prevent or delay the initiation and progression of atherosclerosis by following steps for heart-healthy living.

You’ve probably heard the terms coronary heart disease (CHD) or artery disease in connection with heart health. The two terms are sometimes used interchangeably, but the difference is that coronary heart disease is just one type of arterial disease. 

Coronary arterial disease is categorized as the narrowing or blockage of arteries, which is often linked to atherosclerosis, the buildup of plaques and cholesterol in your arteries. You may wonder, “Is coronary artery disease the same as atherosclerosis?” The answer is that atherosclerosis is what causes coronary arterial disease. It also causes other types of arterial disease, including peripheral artery disease, carotid artery disease, and renal vascular disease. 

Coronary arterial disease (CAD) is plaque buildup in the coronary arteries. For your heart to function properly, it needs a steady supply of blood to pump through your body. Plaque buildup in coronary arterial disease makes your heart work harder to pump its blood, limiting the oxygen and nutrients passed through your heart. 

Without treatment, coronary arterial disease can cause a heart attack. This life-threatening condition happens when plaque builds up so much that it blocks the artery, stopping blood from flowing at all. Common heart attack symptoms include cold sweats, nausea, chest pain, shoulder pain, and shortness of breath. After a time, coronary arterial disease and heart attacks can lead to a weakened heart that cannot pump blood as it should (heart failure).

If you or someone you know experiences these symptoms, seek emergency medical help immediately. Schedule a consultation with one of our renowned vascular doctors at USA Vascular Centers to learn more about how atherosclerosis can impact your arteries. Our board-certified doctors can answer questions about CAD signs and symptoms and help you understand the difference between coronary artery disease vs. peripheral artery disease.

CAD Risk Factors

Learning about the controllable risk factors of coronary arterial disease can help you take steps to prevent the onset of the disease. The most common CAD risk factors you can avoid include smoking, high cholesterol, high blood pressure, type 2 diabetes, obesity, stress, and an unhealthy lifestyle. 

There are risks of coronary arterial disease that are not preventable or cannot be treated. It is important to know these risk factors so you can maintain the controllable risks if you fall into any of the following categories:

  • Gender: men have an increased risk over women
  • Age: as your age increases, so does the risk of CAD
  • Genetics: family history of heart disease

You may have already known the risk factors of heart disease, but may not be as familiar with the causes of the disease. A major cause of heart disease is atherosclerosis, which is the buildup of plaque and cholesterol in your arteries. 

Many of us associate plaque with what dentists scrape off our teeth, but arterial plaque is made up of different substances like: calcium, fat, cholesterol, cellular waste, and fibrin. These substances are circulated with your blood which can eventually build up and clog your arteries.

Plaque buildup can lead to different conditions depending on where the plaque develops and which artery is affected. Common arteries that experience plaque buildup are:

  • Coronary arteries: lead blood to or in the heart
  • Renal arteries: supply blood to the kidneys
  • Carotid arteries: provide blood to your brain, neck, and face
  • Peripheral arteries: supply blood to the body (i.e., arms and legs)

Blockages in any of the above-mentioned arteries can cause issues for your body. It is more common to focus on the arteries that supply blood to your heart or brain, but blockages in the peripheral arteries can cause Peripheral Artery Disease (PAD). While there is a clear difference between coronary artery disease vs. peripheral artery disease, both are similar in that both are caused by atherosclerosis, share the same risk factors, and can lead to more serious conditions. People with PAD have a higher risk of heart attack, stroke, gangrene, or amputation.

Symptoms of PAD are more common in your legs and include:

  • Heaviness or cramping in your legs
  • Pain in your legs that disturbs your sleep
  • Sores or wounds on your legs and feet that heal slowly or not at all
  • Skin color changes
  • Poor hair and nail growth on legs and feet

Many people mistake PAD symptoms for normal signs of aging and put off going to the doctor. But knowing the common symptoms of PAD will alert you to the warning signs so you can seek help sooner rather than later.

Arterial disease, whether arterial heart disease or peripheral artery disease, is a dangerous condition that can affect your body differently. Maintaining a healthy lifestyle, regularly going to the doctor, and paying attention to your body will help prevent arterial and heart disease. Through education and talking about our experiences, we can beat arterial diseases.

If you’re experiencing any of the symptoms of PAD, are over the age of 50, have a history of smoking or vascular disease in your family, or have diabetes, schedule an arterial check online today!

Does atherosclerosis cause coronary artery disease?

When atherosclerosis narrows the arteries close to your heart, you may develop coronary artery disease, which can cause chest pain (angina), a heart attack or heart failure.

What is coronary artery disease called?

Plaques and blood clots can reduce blood flow through an artery. Coronary artery disease starts when fats, cholesterols and other substances collect on the inner walls of the heart arteries. This condition is called atherosclerosis.

Is there a difference between coronary heart disease and coronary artery disease?

Is there a difference? The short answer is often no — health professionals frequently use the terms interchangeably. However, coronary heart disease , or CHD, is actually a result of coronary artery disease, or CAD, said Edward A. Fisher, M.D., Ph.
