Infarction occurs as a result of prolonged ischemia, which is the insufficient supply of oxygen and nutrition to an area of tissue due to a disruption in blood supply.The blood vessel supplying the affected area of tissue may be blocked due to an obstruction in the vessel (e.g., an arterial embolus, thrombus, or atherosclerotic plaque), compressed by something outside of the vessel causing it ...
Terminology. Myocardial infarction (MI) refers to tissue death ( infarction) of the heart muscle ( myocardium) caused by ischemia, the lack of oxygen delivery to myocardial tissue. It is a type of acute coronary syndrome, which describes a sudden or short-term change in symptoms related to blood flow to the heart. [22]
Specialty. Neurology. Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]
Stroke (also known as a cerebrovascular accident ( CVA) or brain attack) is a medical condition in which poor blood flow to the brain causes cell death. [5] There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. [5] Both cause parts of the brain to stop functioning properly.
Terminology. Thrombosis is defined as the formation of a thrombus (blood clot) inside a blood vessel, leading to obstruction of blood flow within the circulatory system. Coronary thrombosis refers to the formation and presence of thrombi in the coronary arteries of the heart. Note that the heart does not contain veins, but rather coronary ...
Coronary ischemia, myocardial ischemia, [1] or cardiac ischemia, [2] is a medical term for abnormally reduced blood flow in the coronary circulation through the coronary arteries. [3] Coronary ischemia is linked to heart disease, and heart attacks. [4] Coronary arteries deliver oxygen-rich blood to the heart muscle. [5]
Cerebrovascular disease includes a variety of medical conditions that affect the blood vessels of the brain and the cerebral circulation. Arteries supplying oxygen and nutrients to the brain are often damaged or deformed in these disorders. [2] The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and ...
Specialty. Vascular surgery. Ischemia or ischaemia is a restriction in blood supply to any tissue, muscle group, or organ of the body, causing a shortage of oxygen that is needed for cellular metabolism (to keep tissue alive). [3] [4] Ischemia is generally caused by problems with blood vessels, with resultant damage to or dysfunction of tissue ...
