If the blood vessels became blocked with fatty deposits it will create an Atherosclerosis . Atherosclerosis occurs when your arteries become clogged with plaque , causing them to lose their elasticity and become narrower . Plaque is a sticky mixture of fatty streaks that build up , making the walls of the arteries thick and hard .
Inflammation causes the vessel wall to swell. This makes blood stick to the inner wall to form a clot.
Vasculitis should not be confused with "vasculopathy," which simply means something is wrong with the blood vessels. If there is no inflammation, it is not vasculitis. (Vasculitis is one type of vasculopathy.) Some people – even physicians, but especially writers on the internet – incorrectly use these words interchangeably. Unfortunately, even some doctors use the term vasculitis to mean "an autoimmune disease and blood vessel abnormality that I don't completely understand." That is, they use "vasculitis" very loosely as a general term for autoimmune disease.
Diseases in Which Vasculitis Is the Specific Illness, Rather Than a Complication of Another Disease 1 Polyarteritis nodosa, which affects middle-aged people 2 Temporal arteritis or giant cell arteritis, which affects arteries, usually in the head, of older people 3 Allergic vasculitis, which is an abrupt reaction that sometimes follows infection 4 Takayasu's arteritis, which is a relatively rare disease of young women, largely in Asia, involving large blood vessels 5 Wegener's granulomatosis, which affects the kidneys, lungs and blood vessels 6 Some of the new cancer drugs, called checkpoint inhibitors, sometimes cause vasculitis
The symptoms of medium-vessel vasculitis include: 1 Fever 2 Severe muscle aches 3 Sudden loss of power in specific muscles (perhaps a foot starts dragging) 4 Severe abdominal pain 5 Sudden loss of circulation in a finger or toe that turns totally black 6 Stroke or heart attack
Small-Vessel Vasculitis. This is the most common form of vasculitis seen in lupus and it is fairly common in dermatomyositis and scleroderma, but less common in rheumatoid arthritis. The small vessels are at your fingertips and inside your organs, such as the kidneys.
This is the most common form of vasculitis seen in lupus and it is fairly common in dermatomyositis and scleroderma, but less common in rheumatoid arthritis. The small vessels are at your fingertips and inside your organs, such as the kidneys. Some signs of it can be seen externally with a small magnifying glass.
These vessels include those that lead down your arms and legs, and also to your heart and brain, and even those supplying blood to your intestines or kidneys. Medium-vessel vasculitis is usually what physicians are referring to when they call vasculitis a serious disease. (For example, polyarteritis nodosa, a type of vasculitis that has its own name, tends to be very dramatic. People who have it say they have never felt worse in their lives.) Medium-vessel disease can occur in lupus and RA, but it is rare.
Sometimes, when arteries become completely blocked, a new blood supply develops around the blockage. This new blood supply, called collaterals, won't deliver as much blood to your heart. This can lead to those same symptoms of chest pain and shortness of breath.
In cardiology, the boulder is called a Chronic Total Occlusion (CTO). It means the artery is completely blocked. This occurs in 15% to 20% of patients who have heart disease. Sometimes there has been a complete blockage for many months or even years. However, only about 3% to 5% of these patients undergo a stent or bypass procedure, ...
Blocked tunnels aren’t good for traffic flow, and blocked arteries aren’t good for your heart. In cardiology, the boulder is called a Chronic Total Occlusion (CTO). It means the artery is completely blocked. This occurs in 15% to 20% of patients who have heart disease.
