Stroke is a serious condition of blood vessel disorder caused by the stop of blood supply to the brain. Brain cells with ceased oxygen supply from blood will die in millions per second. [ 14 ] Not only is it one of the major causes of death around the world, it is also the cause of permanent disability.
It affects all of the vessels: very small blood vessels (capillaries), medium-size blood vessels (arterioles and venules), or large blood vessels (arteries and veins). If blood flow in a vessel with vasculitis is reduced or stopped, the parts of the body that receive blood from that vessel begins to die, resulting in a stroke.
The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and sometimes a hemorrhagic stroke. [2] Hypertension (high blood pressure) is the most important contributing risk factor for stroke and cerebrovascular diseases as it can change the structure of blood vessels and result in atherosclerosis .

Percutaneous coronary intervention (coronary angioplasty with stent placement): A percutaneous coronary intervention involves opening up a narrowed artery in your heart with a thin tube called a ...
Vasoconstriction is the narrowing of the blood vessels resulting from contraction of the muscular wall of the vessels, in particular the large arteries and small arterioles. The process is the opposite of vasodilation, the widening of blood vessels. The process is particularly important in controlling hemorrhage and reducing acute blood loss.
Arteriosclerosis, literally meaning "hardening of the arteries", is an umbrella term for a vascular disorder characterized by abnormal thickening, hardening, and loss of elasticity [3] of the walls of arteries; [4] this process gradually restricts the blood flow to one's organs and tissues and can lead to severe health risks brought on by atherosclerosis, which is a specific form of ...
This is caused by an increase in the pressure of the blood flowing through the vessels. Hypertension can lead to heart failure and stroke. Aspirin helps prevent blood clots and can also help limit inflammation. [37] Vasculitis is inflammation of the vessel wall due to autoimmune disease or infection.
Dr. Denniston notes that signs of poor blood circulation can include leg pain after walking, cold hands and feet, white fingertips, varicose veins, slow wound healing, numbness, tingling, blue ...
