Microangiopathy (also known as microvascular disease, small vessel disease (SVD) or microvascular dysfunction) is a disease of the microvessels, small blood vessels in the microcirculation. [1] It can be contrasted to macroangiopathies such as atherosclerosis , where large and medium-sized arteries (e.g., aorta , carotid and coronary arteries ...
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
Acute ischemic stroke is a neurological emergency typically caused by a blood clot blocking blood flow in a vessel in the brain. [15] Chronic ischemia of the brain may result in a form of dementia called vascular dementia. [16] A sudden, brief episode (symptoms lasting only minutes) of ischemia affecting the brain is called a transient ischemic ...
Advanced age, chronic hypertension, smoking and diabetes mellitus are risk factors. It is unclear whether there is an association with alcohol consumption, elevated cholesterol, or history of prior stroke. Lacunar strokes may result from carotid artery pathology or microemboli from the heart as in atrial fibrillation.
A transient ischemic attack (TIA) is also called a “mini stroke”. ... The primary treatment for atherosclerosis is making lifestyle changes to help prevent the further build-up of plaque in ...
Chronic diabetes can lead to several problems, one of which is Diabetic Angiopathy. Individuals with diabetic angiopathy notice a constriction in their arteries. This cause many organs to receive insufficient blood and oxygen, which might eventually cause harm. High blood sugar is the primary cause of diabetic angiopathy. Excessive blood sugar ...
Ischemia is the loss of blood flow to the focal region of the brain. This produces heterogeneous areas of ischemia at the affected vascular region, furthermore, blood flow is limited to a residual flow. Regions with blood flow of less than 10 mL/100 g of tissue/min are core regions (cells here die within minutes of a stroke).
Microvascular angina is a chronic long term condition which increases the risk of heart attack and other cardiac events such as heart failure and frequent hospital admissions. The treatment consists of drugs, mainly to relieve chest pain, but a very important part of the treatment is regularly visiting the doctor and repeating the tests to make ...
