What does the term 'stenosis' refer to?

The term 'stenosis' specifically refers to the narrowing of a blood vessel, which can lead to restricted blood flow. This condition can occur in various parts of the cardiovascular system, including arteries and veins. When a blood vessel narrows, it can impede the normal flow of blood, potentially causing complications such as ischemia, where tissues do not receive adequate blood supply. The significance of recognizing stenosis lies in its impact on overall cardiovascular health, as it can lead to conditions like angina, claudication, or even more severe problems such as heart attacks or strokes if blood supply is critically reduced. Understanding this term is essential for anyone studying vascular health, as it helps identify risks associated with cardiovascular diseases.
