Fibromuscular Dysplasia in Coronary Arteries

Fibromuscular Dysplasia (FMD) is a rare disorder that affects the blood vessels, including the coronary arteries, which supply blood to the heart muscle. In FMD, the walls of the arteries become thickened and stiff, leading to narrowing or blockages that can affect blood flow to the heart.

Types of Fibromuscular Dysplasia:

1. Medial Fibroplasia: This type involves thickening of the muscular layer of the artery wall.
2. Intimal Fibroplasia: Here, the inner lining of the artery thickens, leading to narrowing of the artery.

Causes of Fibromuscular Dysplasia:

1. Genetics: FMD can run in families, suggesting a genetic predisposition.
2. Hormonal Factors: Changes in hormone levels, especially in women, may contribute to FMD development.
3. Smoking: Tobacco use has been linked to an increased risk of developing FMD.
