Anemia is strictly defined as a decrease in red blood cell (RBC) mass. The function of the RBC is to deliver oxygen from the lungs to the tissues and carbon dioxide from the tissues to the lungs. This is accomplished by using hemoglobin (Hb), a tetramer protein composed of heme and globin. In anemia, a decrease in the number of RBCs ...

Atrial fibrillation (AF or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by rapid and irregular beating of the atrial chambers of the heart. It often begins as short periods of abnormal beating, which become longer or continuous over time. It may also start as other forms of arrhythmia such as atrial flutter that then transform into AF.

Ischemic stroke is caused by a blood clot that blocks or plugs a blood vessel in the brain. This is the most common type; about 80% of strokes are ischemic. Hemorrhagic stroke is caused by a blood vessel that breaks and bleeds into the brain. Another condition that's similar to a stroke is a transient ischemic attack (TIA).

A stroke occurs when the supply of blood in the brain becomes compromised. This can happen by either a blood clot obstructing an artery and stopping blood flow to an area of the brain (called an ischemic stroke) or an artery in the brain bursting and leading to bleeding inside the brain (called a hemorrhagic stroke).

Background Circle of Willis is the main structure that provides constant and regular blood flow to the brain, protects the brain from ischemia. Stroke has remained the second leading cause of death globally in the last fifteen years. It is the fifth leading cause of death in the United States. It is also the leading cause of serious adult disability. Interlinked problems related to ischemic ...

A transient ischemic attack (TIA) is a medical emergency. It is defined as a transient episode of neurologic dysfunction due to the focal brain, spinal cord, or retinal ischemia, without acute infarction or tissue injury. The definition of a TIA has moved from time-based to tissue-based. A TIA typically lasts less than an hour, more often minutes. TIA can be considered as a serious warning for ...

Myocardial infarction (MI), colloquially known as "heart attack," is caused by decreased or complete cessation of blood flow to a portion of the myocardium. Myocardial infarction may be "silent" and go undetected, or it could be a catastrophic event leading to hemodynamic deterioration and sudden death.[1] Most myocardial infarctions are due to underlying coronary artery disease, the ...

Common causes of stroke come from blood vessels both outside and inside the brain. Atherosclerosis (hardening of the arteries) can occur when plaque (deposits of cholesterol, calcium, fat, and other substances) builds up and narrows the vessel, making it easy for clots to form and further occlude the vessel. The clots can break free only to ...

The type and severity of parietal stroke symptoms are based largely on the location and size of the injury, but can include impairment of speech, thought, coordination, and movement.

Overview. Acute myocardial infarction (MI) indicates irreversible myocardial injury resulting in necrosis of a significant portion of myocardium (generally >1 cm). The term "acute" denotes infarction less than 3-5 days old, when the inflammatory infiltrate is primarily neutrophilic. Acute MI may be either of the nonreperfusion type, in which ...

Etiology. The etiology of ischemic stroke is due to either a thrombotic or embolic event that causes a decrease in blood flow to the brain. In a thrombotic event, the blood flow to the brain is obstructed within the blood vessel due to dysfunction within the vessel itself, usually secondary to atherosclerotic disease, arterial dissection, fibromuscular dysplasia, or inflammatory condition.
