What causes cerebral infarction?

What causes cerebral infarction?

Cerebral infarct: Cerebral infarction, or stroke, occurs due to suddenly decreased blood supply to part of the brain. This is common when a piece of arterial debris or a blood clot lodges in a small artery. The risk factors for stroke are smoking, high blood pressure, high blood cholesterol, high blood sugar, and arterial disease. ...Read more

What causes thrombosis of the coronary arteries?

What causes thrombosis of the coronary arteries?

Arterioclerosis: Arteriosclerosis or plaque buildup in the wall of the coronary arteries will narrow the lumen to the point where there is flow restriction, then clot formation. The plaque may rupture, allowing a flap-like effect, blocking the lumen, resulting in clot formation. Trauma may cause a separation of the layers of the wall, and this dissection results in clot formation. ...Read more

What are the complication of myocardial infarction?

What are the complication of myocardial infarction?

Several possible: There are a range of possible complications. The heart is a muscle, and can be weakened by a heart attack and lead to heart failure. The heart has a conduction system which can be damaged and can lead to arrhythmias and cardiac arrest. Many people die from their heart attack, while others have one and don't realize it. Unfortunately about 1/2 of the time the first sign of heart disease is death. ...Read more

What is the pathogenesis of an ischaemic stroke affecting the left cerebral hemisphere?

What is the pathogenesis of an ischaemic stroke affecting the left cerebral hemisphere?

Mechanisms: Usually, represents narrowing and closure of a large artery such as carotid or middle cerebral, but can be due to a clot circulating from a distant source, such as heart. A myocardial event might trigger a stroke in a susceptible older patient, and, in some cases, trauma can tear a blood vessel in neck (dissection). Causes include smoking, hypertension, diabetes, hyperlipemia, high homocysteine. ...Read more

What are the differences between myocardial infarction and myocardial ischemia?

What are the differences between myocardial infarction and myocardial ischemia?

Ischemia: Ischemia is a term for tissue not getting enough oxygen(almost the same as not enough blood supply). Infarction is the end result of too much ischemia, it means death of the tissue. In other words infarction is the result of severe prolonged ischemia. ...Read more

What is transient cerebral ischemia?

What is transient cerebral ischemia?

You mean a TIA: Transient ischemic attack (TIA) is often called a "mini-stroke, " and is considered a harbinger for a full-blown stroke. It can occur as a result of a narrowing in the carotid arteries. Unlike a stroke, TIA symptoms last anywhere from 15 minutes to 24 hours. Typically can present with blindness to one eye, paralysis, or slurred speech. You should see a vascular surgeon immediately. ...Read more

Pathogenesis of an ischaemic stroke affecting the left cerebral hemisphere. What does this mean?

Words: Pathogenesis is the origin or development of a disease. Ischemic stroke is damaged brain tissue due to loss of circulation (like from a clot)(as opposed to stroke from bleeding). Left cerebral hemisphere is the dominant area in most people and usually controls speech and right sided motor functions. ...Read more
