Atherosclerotic Plaque in Coronary Arteries

Atherosclerotic plaque in coronary arteries is a condition where fatty deposits build up in the walls of the arteries that supply blood to the heart muscle. This buildup can narrow or block the arteries, leading to various heart problems. In this article, we will explore the types, causes, symptoms, diagnostic tests, treatments, drugs, and surgeries associated with atherosclerotic plaque in simple, easy-to-understand language.

Types of Atherosclerotic Plaque:

  1. Stable Plaque: This type of plaque is more solid and less likely to cause sudden blockages.
  2. Unstable Plaque: Unstable plaque is prone to rupture, leading to sudden blockages and potentially dangerous consequences.

Causes of Atherosclerotic Plaque:

  1. High Cholesterol: When there is too much cholesterol in the blood, it can accumulate in the arteries, forming plaque.
  2. High Blood Pressure: Increased pressure on the artery walls can damage them and promote plaque formation.
