What is Microvascular Disease?

Microvascular disease, also referred to as coronary microvascular disease or small vessel disease, is a type of heart disease that affects the walls and inner lining of the small blood vessels in the heart, known as the microvessels. Unlike coronary artery disease, which involves blockages in the larger coronary arteries, microvascular disease is characterized by damage to the inner walls of these smaller vessels, leading to spasms and reduced blood flow to the heart muscle.

Microvascular disease often has a higher prevalence in women, particularly younger women. It shares similar risk factors with coronary artery disease, including diabetes, high blood pressure, and high cholesterol. The impaired blood flow resulting from microvascular disease can deprive the heart muscle of the oxygen and nutrients it needs to function properly, leading to symptoms such as chest pain, shortness of breath, and fatigue.

Diagnosing microvascular disease can be challenging, as traditional tests for coronary artery disease may not detect abnormalities in the smaller coronary arteries affected by microvascular disease. However, advancements in imaging techniques, such as coronary angiography and stress tests, have improved detection and assessment of blood flow in the coronary arteries, aiding in the diagnosis of microvascular disease.
