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 ]
Symptoms of the acute coronary syndromes are similar. [8] The cardinal symptom of critically decreased blood flow to the heart is chest pain, experienced as tightness, pressure, or burning. [9] Localization is most commonly around or over the chest and may radiate or be located to the arm, shoulder, neck, back, upper abdomen, or jaw. [9]
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 ...
Information card published by the National Heart, Lung, and Blood Institute urging people with symptoms of angina to call the emergency medical services.. Because of the relationship between the duration of myocardial ischemia and the extent of damage to heart muscle, public health services encourage people experiencing possible acute coronary syndrome symptoms or those around them to ...
An ischemic stroke's main cause is atherosclerosis. [2] Stroke is commonly caused by atherosclerotic large vessel disease and results from local branch occlusion by plaque, artery-to-artery embolism, or in situ thrombosis, with the latter being the most common cause of anterior cerebral artery infarction. [4]
A condition called peripheral artery disease (PAD), for example, occurs when the arteries that carry blood from the heart to the legs get clogged; it’s associated with an increased risk of heart ...
Long QT syndrome (LQTS) is a condition affecting repolarization (relaxing) of the heart after a heartbeat, giving rise to an abnormally lengthy QT interval. [7] It results in an increased risk of an irregular heartbeat which can result in fainting, drowning, seizures, or sudden death. [1]
It can be seen in approximately 4% of cases of acute myocardial infarction [citation needed] It is the most common type of intraventricular conduction defect seen in acute anterior myocardial infarction, and the left anterior descending artery is usually the culprit vessel. It can be seen with acute inferior wall myocardial infarction.
