Fibrous plaques

Definition

Fibrous plaques are hardened deposits that form within the arterial walls due to the accumulation of fatty substances, cholesterol, and cellular waste. They contribute to the narrowing and stiffening of arteries, which can impede blood flow.

5 Must Know Facts For Your Next Test

1. Fibrous plaques are commonly found in patients with atherosclerosis, a condition linked to cardiovascular diseases.
2. The development of fibrous plaques is influenced by factors such as poor diet, smoking, and chronic inflammatory conditions.
3. In the context of pulmonary health, fibrous plaques can exacerbate conditions like chronic obstructive pulmonary disease (COPD) by reducing oxygen supply to tissues.
4. Nutritional interventions that include antioxidants and anti-inflammatory foods can help slow the progression of fibrous plaque formation.
5. Omega-3 fatty acids have been shown to reduce inflammation and may help prevent the development of fibrous plaques.
