What Is Arterial Plaque?
Arterial plaque is a buildup of fats, cholesterol, calcium, cellular waste, and other substances inside the walls of the arteries. Over time, plaque hardens and narrows the arteries, reducing blood flow to the heart, brain, and other organs. This process is known as atherosclerosis.
If plaque ruptures, it can trigger the formation of a blood clot, potentially leading to a heart attack, stroke, or other serious cardiovascular event.
Why Arterial Plaque Matters
As plaque accumulates, arteries become narrower and less flexible, making it more difficult for oxygen-rich blood to reach the body’s tissues. Early detection and treatment help reduce the risk of life-threatening complications.
Risk Factors for Arterial Plaque
- High cholesterol
- High blood pressure
- Smoking
- Diabetes
- Obesity
- Physical inactivity
- Unhealthy diet
- Older age
- Family history of cardiovascular disease
Possible Symptoms
Arterial plaque usually causes no symptoms until blood flow becomes significantly restricted. Depending on the affected artery, symptoms may include:
- Chest pain (angina)
- Shortness of breath
- Leg pain while walking
- Weakness or numbness
- Stroke symptoms
- Slow-healing wounds
How Is Arterial Plaque Diagnosed?
Healthcare providers may use cholesterol testing, coronary calcium scoring, ultrasound, CT angiography, MR angiography, stress testing, or conventional angiography to evaluate plaque buildup.
How Is Arterial Plaque Treated?
Treatment includes heart-healthy lifestyle changes, cholesterol-lowering medications, blood pressure management, diabetes control, smoking cessation, regular exercise, and procedures such as angioplasty or bypass surgery in severe cases.
How Home Care Can Help
Home care professionals encourage medication adherence, support healthy eating, monitor blood pressure, promote regular physical activity, assist with chronic disease management, and educate individuals about reducing cardiovascular risk.
Home Care Tip
Lowering LDL (“bad”) cholesterol and controlling blood pressure are two of the most effective ways to slow plaque buildup and protect your heart.
Frequently Asked Questions About Arterial Plaque
Can arterial plaque disappear?
Although plaque usually cannot be completely eliminated, treatment and healthy lifestyle changes can slow its progression, stabilize existing plaque, and reduce the risk of complications.
Does arterial plaque always cause symptoms?
No. Many people have plaque buildup for years without symptoms until a significant blockage or cardiovascular event occurs.
Can home care help people with arterial plaque?
Yes. Home care professionals support medication management, healthy lifestyle habits, monitoring, and education to help reduce cardiovascular risk.
When to Seek Emergency Medical Care
Seek immediate medical attention if you experience chest pain, sudden weakness, facial drooping, difficulty speaking, severe shortness of breath, or other symptoms of a heart attack or stroke.
