Ischemic stroke definition

Ischemic stroke is the third leading cause of death in the United States and a common reason for hospitalization. The subacute period after a stroke refers to the time when the decision to not employ thrombolytics is made up until two weeks after the stroke occurred. Family physicians are often involved in the subacute management of ischemic stroke. All patients with an ischemic stroke should be admitted to the hospital in the subacute period for cardiac and neurologic monitoring. Imaging studies, including magnetic resonance angiography, carotid artery ultrasonography, and/or echocardiography, may be indicated to determine the cause of the stroke. Evaluation for aspiration risk, including a swallowing assessment, should be performed, and nutritional, physical, occupational, and speech therapy should be initiated. Significant causes of morbidity and mortality following ischemic stroke include venous thromboembolism, pressure sores, infection, and delirium, and measures should be taken to prevent these complications. For secondary prevention of future strokes, antiplatelet therapy with aspirin should be initiated within 24 hours of ischemic stroke in all patients without contraindications, and one of several antiplatelet regimens should be continued long-term. Statin therapy should also be given in most situations. Although permissive hypertension is initially warranted, antihypertensive therapy should begin within 24 hours. Diabetes mellitus should be controlled and patien...

A stroke occurs when the body stops supplying blood to the brain. Ischemic stroke is the most common type of stroke, and it develops due to a blockage in the arteries around the brain. According to the Centers for Disease Control and Prevention (CDC), Around In this article, we explain the causes of ischemic stroke, how to recognize when one is occurring, and ways to prevent and treat it. Share on Pinterest Ischemic stroke is the most common type, and early intervention is vital. An ischemic stroke occurs due to When too much plaque collects in one spot, it can block the blood flow to vital organs. A blood clot may stick to a plaque buildup while passing through the blood vessels, which also creates a blockage. The neck contains carotid arteries, which are blood vessels that supply blood to the brain. If plaque blocks a carotid artery (carotid artery disease), a stroke might occur. Atherosclerosis is largely symptomless. Therefore, many people do not know they have atherosclerosis until they have a stroke or experience the other effects of blocked arteries near different organs, such as a The major risk factors for an ischemic stroke and carotid artery disease are the same. They include: • High blood pressure: This is the • Diabetes: People with • Atherosclerosis or carotid artery disease: Having either of these conditions or a family history of these conditions can increase the risk of stroke. • • Cholesterol levels: High levels of “bad” low-density lipoprotein (LDL) chol...

Ischemic stroke is an episode of neurological dysfunction due to focal infarction in the central nervous system attributed to arterial thrombosis, embolization, or critical hypoperfusion. While ischemic stroke is formally defined to include brain, 1, in common usage, it mainly refers to cerebral infarction, which is the focus of this article.

Bridging these terms, ischemic stroke is the subtype of stroke that requires both a clinical neurologic deficit and evidence of Epidemiology 2. Risk factors for ischemic stroke largely mirror the risk factors for Clinical presentation An ischemic stroke typically presents with rapid onset neurological deficit, which is determined by the area of the brain that is involved. The symptoms often evolve over hours and may worsen or improve, depending on the fate of the ischemic penumbra.

This initiates a cascade of events at a cellular level which, if circulation is not re-established in time, will lead to cell death, mostly through liquefactive necrosis. The mechanism of vessel obstruction is important in addressing therapeutic maneuvers to both attempt to reverse or minimize the effects and to prevent future infarcts.

• Face: Ask the person to smile. Does one side of their face droop? • Arms: Ask the person to raise both arms. Does one of the arms drift downward or are they unable to raise either one of their arms? • Speech: Ask the person to repeat a simple phrase. Is their speech slurred? • Time: Seek immediate medical attention if you observe any of these signs. • Tsao CW, Aday AW, Almarzooq ZI, et al.
