What is Narrowing of in Artery?

Narrowing of an artery, often referred to as arterial stenosis, occurs when the blood vessels constrict or become obstructed, reducing blood flow. This condition can result from plaque buildup due to atherosclerosis, inflammation, or other factors. Narrowing can lead to various health issues, including angina, heart attacks, or peripheral artery disease, depending on the affected area. Timely diagnosis and treatment are essential to manage symptoms and prevent complications.
