Atherosclerosis is a condition where arteries become narrowed and hardened due to a buildup of plaque. This plaque is made up of substances like fat, cholesterol, and calcium. When this happens in the posterior interventricular artery, it can lead to various health issues. In this article, we’ll break down what atherosclerotic plaque in the posterior interventricular artery is, its causes, symptoms, diagnostic tests, treatments, medications, surgeries, and more.

The posterior interventricular artery is a blood vessel that supplies oxygen-rich blood to the lower part of the heart. When plaque builds up in this artery due to atherosclerosis, it can restrict blood flow to the heart muscle, leading to various complications.

Types of Atherosclerotic Plaque in the Posterior Interventricular Artery:

There are several types of plaque that can develop in the posterior interventricular artery, including:

1. Fatty streaks: Early-stage plaque made up of fat deposits.
2. Fibrous plaque: Contains connective tissue and cholesterol.
3. Calcified plaque: Hardened plaque due to calcium deposits.
4. Vulnerable plaque: Prone to rupture, leading to blood clots and blockages.

Causes of Atherosclerotic Plaque in the Posterior Interventricular Artery:

1. High cholesterol levels.
