People with coronary artery disease, or narrowing of the blood vessels supplying their heart, may develop symptoms such as: Chest pain that often gets worse with stress or physical activity ...
Blood vessel disorder generally refers to the narrowing, hardening or enlargement of arteries and veins. It is often due to the build-up of fatty deposits in the lumen of blood vessels or infection of the vessel wall. This can occur in various locations such as coronary blood vessels, peripheral arteries and veins.
The narrowing of blood vessels leads to an increase in peripheral resistance, thereby elevating blood pressure. While vasoconstriction is a normal and essential regulatory mechanism for maintaining blood pressure and redistributing blood flow during various physiological processes, its dysregulation can contribute to pathological conditions.
It can suggest a problem in the heart or blood vessels that reduces blood flow through the body. Research suggests that ED is associated with a two-fold increase in heart attack, stroke, and death ...

The thrombus then travels downstream to other blood vessels, where the blood clot may partially or completely block blood flow. If the blood flow is completely blocked, cell deaths occur due to the lack of oxygen supply to nearby cells, resulting in necrosis. [81] The narrowing or obstruction of blood flow can occur in any artery within the body.

Symptoms can be less severe during gradual narrowing, as this allows time for the widening of existing vessels and the formation of new ones (collateral vessels), allowing blood to still reach the area. Symptoms in this case will simply be intermittent claudication. [3]
