What is an "atherosclerotic plaque"?

Atherosclerotic plaque refers to the accumulation of fat, cholesterol, and other substances in the walls of arteries, leading to a condition known as atherosclerosis. This buildup can cause the arteries to narrow and restrict blood flow, significantly increasing the risk of cardiovascular events such as heart attacks and strokes. The plaque consists of lipid deposits and inflammatory cells, and its formation is often influenced by factors like high cholesterol levels, smoking, and hypertension.

Understanding atherosclerotic plaques is crucial because they play a significant role in cardiovascular diseases, serving as a precursor to more severe conditions when they rupture or lead to blockages. Recognizing this definition and its implications in cardiovascular health is essential for effective prevention and management of heart-related conditions.
