20 Interesting Facts About Atherosclerosis + Statistics & Causes

20 Interesting Facts About Atherosclerosis + Statistics & Causes

Atherosclerosis is a generic term which refers to the hardening and thickening of the arteries – the blood vessels which bear the full force of each heartbeat.

The most common locations for atherosclerosis are:

  • arteries which supply the brain, known as carotid artery disease;
  • arteries which supply the legs, known as peripheral arterial disease;
  • arteries in the heart, known as coronary atherosclerosis (which is the number 1 killer in America).

List Of 20 Interesting Facts About Atherosclerosis:


#1 In the US, 7 percent of women aged 65 or older have carotid arteries which are more than 50 percent blocked by atherosclerosis. About 8.5 million Americans have peripheral arterial disease. Also, 1 of every 13 people in the United States aged 18 years and older has coronary artery disease.

#2 Worldwide, cardiovascular diseases take the lives of over 18 million people per year. In Spain, hardening of the arteries is responsible for over 125,000 deaths every year.

#3 It occurs when your arteries become clogged with fatty deposits, causing them to become narrower.

Risk Factors

#4 If modifiable risk factors are addressed properly, it is estimated that around 90 percent of the atherosclerotic disease burden may be preventable.

#5 Risk factors for hardening of the arteries include:

  • having a regular diet rich in saturated and trans-fats, such as – hamburgers, French fries, hot-dogs, onion rings, doughnuts, milk chocolate, cheese, margarine, mayonnaise, cakes;
  • sedentarism (physical inactivity);
  • high triglyceride levels;
  • obesity;
  • type 1 diabetes;
  • smoking tobacco and regular exposure to second-hand smoking;
  • hypertension (high blood pressure);
  • high LDL and total cholesterol levels, especially LDL;
  • high levels of C-reactive protein (a substance that is produced by the liver in response to inflammation);
  • low level of HDL cholesterol.

#6 Even small calcium deposits in the arteries of children and adolescents can predict an early heart attack within several decades, according to a study published in the journal JAMA Cardiology.


#7 As hardening of the arteries progresses, clogged arteries can trigger a stroke or a heart attack, with the following symptoms:

  • kidney failure;
  • chest pressure or pain;
  • high blood pressure;
  • sudden leg or arm weakness;
  • pain when walking;
  • drooping facial muscles;
  • brief loss of vision in one eye;
  • difficulty speaking;
  • slurred speech.

#8 Note – about 50 percent of people who have severe atherosclerosis experience no symptoms.


#9 Over time, hardening of the arteries can lead to:

  • peripheral arterial disease – it is the restriction of blood flow in the arteries of the leg; without enough oxygen-rich blood, tissues and nerves in these areas can be injured;
  • transient ischaemic attacks – it is caused by a temporary disruption in the blood supply to part of the brain;
  • strokes – occurs when the blood supply to your brain is interrupted;
  • heart attacks – it is the death of a segment of the heart muscle caused by a loss of blood supply;
  • angina –  chest pain caused by not enough blood flow to the heart muscle;
  • coronary heart disease –  a condition which affects the arteries that supply the heart with blood; without an adequate blood supply, the heart becomes starved of the vital nutrients and oxygen it needs to work healthfully.


#10 Atherosclerosis tests include:

  • angiography – it is a medical imaging technique which is used to visualize the inside of organs and blood vessels of the body;
  • physical exam;
  • exercise stress test;
  • electrocardiogram;
  • Doppler ultrasound – it is medical ultrasonography which employs the Doppler effect;
  • blood tests;
  • ankle/brachial index – it is done with inflatable blood pressure cuffs placed on the lower legs and arms.

#11 The goals of treatment include:

  • bypassing plaque-clogged arteries;
  • lowering the risk of blood clots forming;
  • relieving symptoms;
  • reducing risk factors in an effort to stop or slow the buildup of plaque;
  • preventing atherosclerosis-related diseases.

#12 Medications to treat hardening of the arteries are prescribed based on other underlying conditions you may have and the location of the enlarged blood vessels. Medications can include:

  • a clot-busting drug may dissolve blood clots;
  • cholesterol-lowering drugs can protect the heart arteries;
  • calcium channel blockers and diuretics can reduce blood pressure;
  • angiotensin-converting enzyme inhibitors can lower the possibility of a heart attack as they lower blood pressure;
  • beta blocker medications can diminish the risk of heart attack, chest pains, and irregular heart rhythm as well as they can reduce the heart rate and blood pressure;
  • aspirin (acetylsalicylic acid) can prevent platelets from forming blood clots.

Home Remedies

Foods High In Omega-3 Fatty Acids

#13 These essential fats can help protect the heart from atherosclerosis. Best foods high in omega 3 are flax seeds and chia seeds.

Onions & Garlic

#14 Both contain allicin, an organic compound that lowers the levels of LDL cholesterol in the human body.

Red Rice Yeast

#15 It can lower the levels of total and LDL cholesterol.


#16 It contains curcumin, a bright yellow chemical that improves blood circulation in the arteries and prevents damage to the walls of blood vessels.


#17 According to a 2009 study, hawthorn reduces the levels of blood fats.


#18 Prognosis is good when hardening of the arteries is treated early with medicines, healthy lifestyle changes (nutrition, exercise, sleep), or medical procedures.

#19 Lifestyle changes will reduce your risk of atherosclerosis. Things you can do include:


  • get regular moderate physical activity – it also lowers your risk of type 2 diabetes as well as it helps you to better manage your weight;
  • avoid or limit how much alcoholic beverages you drink;
  • avoid fatty foods – include several daily servings of vegetables, legumes, fruits, seeds, and nuts including – tomatoes, watermelons, pears, apples, garlic, onions, sweet potatoes, cabbage, broccoli, cauliflower, chickpeas, potatoes, sweet bell pepper, cayenne pepper, red kidney beans, lentils, oatmeal, quinoa, carrots, prunes, plums, dates, apricots, papayas, pineapples, mangoes, turnips;
  • quit smoking and avoid second-hand smoking;
  • have healthy sleeping patterns – aim for 7 to 8 hours of uninterrupted sleep per night.
