What is Coronary Microvascular Disease?

Condition of the heart that can affect the tiny coronary arteries is known as coronary microvascular disease (MVD). In this condition, the walls of the heart’s tiny arteries are damaged or diseased.

Coronary MVD is different from the conventional coronary heart disease, which is also known as coronary artery disease.

In coronary MVD, the tiny arteries in the heart get affected. The plaque does not create blockages in these vessels as it does in the heart’s large arteries.
