Small vessel disease, also known as coronary microvascular disease or small vessel heart disease, is a condition in which the small arteries in the heart become narrowed. Small vessel disease causes signs and symptoms of heart disease, such as chest pain (angina). Small vessel disease is usually diagnosed after a doctor checks for blockages in the main arteries of the heart that cause coronary artery disease, but finds little or no narrowing in the large vessels even though your symptoms persist.
Although anyone can have small vessel disease, it's more common in women and in people who have diabetes. Small vessel disease is treatable, but can be difficult to detect.
