Atherosclerosis is the buildup of fats, cholesterol and other substances in and on the artery walls. This buildup is called plaque. The plaque can cause arteries to narrow, blocking blood flow.
What causes atherosclerosis? Researchers believe atherosclerosis causes may include: High LDL cholesterol and triglyceride levels. Tobacco products. High blood pressure. Diabetes. These factors can damage your artery’s inner lining (endothelium). This causes atherosclerosis to begin. The damage usually occurs slowly and over time.
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.
Atherosclerosis causes heart attacks, strokes, and peripheral vascular disease. Learn about causes, symptoms, risk factors, diagnosis, and treatments.
Atherosclerosis develops slowly as cholesterol , fat, blood cells, and other substances in your blood form plaque in the walls of arteries. As plaque builds up, your arteries narrow. This reduces the supply of oxygen-rich blood to tissues and organs in the body.
Atherosclerosis is a narrowing of the arteries caused by a buildup of cholesterol plaque. It may lead to stroke, heart attacks, dementia, and other health challenges. When plaque builds up and...
It is principally a lipid-driven process initiated by the accumulation of low-density lipoprotein and remnant lipoprotein particles and an active inflammatory process in focal areas of arteries particularly at regions of disturbed non-laminar flow at branch points in the arteries and is considered a primary cause of atherosclerotic cardiovascula...
The oxidized LDL hypothesis postulates that LDL oxidized by various factors including endothelial cells, macrophages and smooth muscle cells of the arterial wall, plays a key role in the development of atherosclerosis.
Atherosclerosis is a condition in which patchy deposits of fatty material (atheromas or atherosclerotic plaques) develop in the walls of medium-sized and large arteries, leading to reduced or blocked blood flow. Atherosclerosis is caused by repeated injury to the walls of arteries.
What is atherosclerosis? Atherosclerosis is the process of cholesterol plaque buildup in arteries. It can lead to a narrowing of the arteries that can significantly reduce the blood supply to vital organs such as the heart, brain, and intestines.
