Atherosclerosis Symptoms Quiz

Atherosclerosis is the buildup of plaque inside arteries. Plaque can include cholesterol, fat, calcium, and other substances. Over time, it can narrow arteries and reduce blood flow.

Atherosclerosis matters because it can raise the risk of heart attack, stroke, and circulation problems in the legs. It often develops slowly and may not cause symptoms at first.

Atherosclerosis is linked to risk factors such as high LDL cholesterol, high blood pressure, diabetes, smoking, family history, aging, and long-term inflammation. Diet, activity level, sleep, and weight can also affect risk.

Yes. Many people do not notice symptoms until an artery becomes significantly narrowed or a plaque causes a sudden problem. That is why routine blood pressure, cholesterol, and blood sugar checks are important.

Atherosclerosis is one cause of heart and blood vessel disease. When it affects arteries that supply the heart, it can contribute to coronary artery disease. It can also affect arteries to the brain, kidneys, or legs.

Symptoms depend on which arteries are affected. Possible signs include chest pressure with activity, shortness of breath, leg pain when walking, numbness or weakness, or stroke-like symptoms. Some people have no symptoms.

A healthcare professional may review symptoms, risk factors, blood pressure, blood tests, and family history. Depending on the concern, they may order tests such as an ECG, stress test, ultrasound, CT scan, or other imaging.

Common tests include a lipid panel, blood glucose, A1C, kidney function tests, and sometimes high-sensitivity CRP or advanced lipid markers. These tests do not diagnose plaque by themselves, but they help estimate risk.

Cholesterol testing does not directly show plaque in the arteries. It can show risk factors that make plaque buildup more likely. Imaging tests are used when a clinician needs to look for plaque or narrowed arteries.

Seek emergency care for chest pressure that is severe, lasts more than a few minutes, happens at rest, or comes with shortness of breath, sweating, nausea, fainting, or pain spreading to the arm, jaw, back, or shoulder. Also get emergency care for sudden weakness, facial droop, trouble speaking, confusion, or vision loss.

Yes. When plaque affects arteries in the legs, it can cause pain, cramping, heaviness, or fatigue during walking that improves with rest. This can be a sign of peripheral artery disease.

It can, especially if blood flow to the heart is reduced or the heart is under strain. Shortness of breath has many possible causes, so new or worsening breathing changes should be discussed with a healthcare professional.

Untreated atherosclerosis may increase the risk of heart attack, stroke, kidney problems, or poor circulation in the legs. Risk can often be reduced by identifying and managing blood pressure, cholesterol, blood sugar, tobacco exposure, and lifestyle factors.

Some risk factors, such as blood pressure, smoking exposure, physical activity, and blood sugar, can begin improving within weeks to months. Cholesterol and long-term plaque risk usually require ongoing monitoring and a sustained plan with a healthcare professional.

Yes. Regular physical activity, a heart-conscious eating pattern, not smoking, healthy sleep, stress management, and keeping blood pressure, cholesterol, and blood sugar in range can help lower cardiovascular risk over time.
