Ischemic Stroke Research Paper

There are two major branches of strokes: those caused by narrowing or blockage of the arteries leading towards the brain, and those caused by blood vessel leaking or rupturing in the brain. Ischemic strokes account for approximately 87% of Stroke cases, which reduces the blood flow to the brain. About half of the Ischemic strokes are caused by clotting in small or large arteries, a smaller portion are caused by

An ischemic stroke is typically caused by a thrombosis, which is a blood clot or an embolism, when the blood clot detaches and infiltrates the blood stream.

Ischemic stroke is the blockage of blood vessels in the brain as a result of blood clots (thrombi), causing the portions of the brain nourished by the vessel and its tributaries to be starved of nutrients, poisoned, and to eventually die (“Symptoms

Mrs. Alice Palmer is a 54-year old married woman who has been admitted and is being treated with an ischemic stroke which she had 18 hours ago. This paper explores the nursing care of Mrs. Alice Palmer based on the clinical reasoning cycle by considering her situation first, collecting cues and information about her, processing the information gathered, then identifying problems or issues she is experiencing, and finally carrying out a detailed assessment. Also, the paper focuses on setting goals and establishing a nursing care plan in the community, and target ethnically safe practice. Ischemic stroke occurs when the brain tissue does not receive sufficient oxygenated blood due to an obstruction of the carotid artery (Brunner, Suddarth, & Smeltzer, 2008). When the brain does not receive enough oxygenated blood, some or all of its tissues may get damaged

A stroke is a type of cardiovascular disease that affects the cerebral arteries, those blood vessels that carry blood to the brain. A stroke occurs when one of those blood vessels in the brain is obstructed or ruptures flooding the brain with blood. Depriving blood and oxygen to the brain results in those immediate cells death, causing the brain not to function properly. Once parts of the brain stop functioning, it can directly affect the areas of the body controlled (1).

A stroke occurs when the blood supply to the brain is blocked. The tissue does not get enough of oxygen and nutrients within minutes, the brain cells begin to die. A stroke is a medical emergency, and prompt treatment is crucial. The good news is a stroke can be treatable and is more preventable. More people live longer now than in the past years. Stroke is known as the silent killer. Many people ignore the symptoms and cause more damage to their body. People with stroke have trouble speaking and understanding, paralysis or numbness of the face arm or leg. If you ever encounter anyone with these systems, please call 911 imminently for help.

As mentioned above, strokes are pathophysiological changes. Ischemia which accounts for 87% of all strokes is a decrease or absent circulating blood which deprives neurons of necessary substrates. As there is no storage of glucose in the brain it leaves no opportunity for the chief ingredient for energy substrate and is incapable of anaerobic metabolism (Shah, MD, n.d.). Ischemia is a medical condition diagnosed when tissues do not have a sufficient oxygen supply, therefor resulting in a decrease in ATP energy, leading to necrosis of tissue. Decreased oxygen supply to tissue (ischemia) is caused by a blockage in an artery mainly from an embolism. An embolism is the breakage of an atherosclerosis formed in any coronary arteries. This floats freely in the blood stream, which eventually may plug a major artery in the brain (stroke), heart (MI) or lungs (lung failure). A thrombus occurs when an already

Often times, doctors will typically call a stroke a “brain attack” because the events that transpire resemble those that occur during a heart attack (Wang and Aamodt, 2010). Blood supplies a constant source of oxygen to the brain. However, a stroke occurs when that blood supply to any given part of the brain is suddenly ceased. If the blood supply to the brain is suddenly interrupted this leads to the deprivation of oxygen and glucose to that area. The brain cells that are prevented from acquiring these substances, especially oxygen, will be quickly killed off. Strokes can be categorized into two classes: Ischemic and hemorrhagic strokes (Lindley, 2008).

Sometimes known as a brain attack, a stroke occurs when blood flow to the brain stops. Brain cells immediately start to die due to the lack of oxygen and nutrients they need to function. There are two types of strokes. The most common type, called ischemic stroke, is caused by a blood clot that blocks a blood vessel in the brain. The other kind of stroke, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. Stroke is the fifth leading cause of death for Americans. In fact, according to the CDC, more than 795,000 people in the United States have a stroke every year. A stroke can cause great damage in the brain and lead to mild or severe disabilities to the entire body such as paralysis, difficulties with

The sudden death of brain cells due to lack of oxygen, caused by blockage of blood flow or rupture of an artery to the brain. Sudden loss of speech, weakness, or paralysis of one side of the body can be symptoms. A suspected stroke may be confirmed by scanning the brain with special X-ray tests, such as CAT scans. The death rate and level of disability resulting from strokes can be dramatically reduced by immediate and appropriate medical care. Prevention involves minimizing risk factors, such as controlling high blood pressure and diabetes. Abbreviated CVA. Also known as cerebrovascular.

The article emphasizes time as a critical aspect to acute ischemic stroke management. The leading method of treatment in AIS is intravenous rtPA because the door-to-needle time is less compared to the time it takes to do methods that use thrombectomy devices or catheterization. I believe that it is vital for people to know the signs and symptoms of acute ischemic stroke because it is one of the leading causes of death and disability. The faster one is able to identify these signs and symptoms, the better an outcome it would be for both the patient and their family members. The general public and hospital staff members should be educated on AIS. This article also briefly touches on the fact that patients suspected of having a more severe stroke (proximal artery occlusion) should be immediately transported to a

“Stroke is the third leading cause of death, after coronary heart disease and cancer. Each year there are about 600,000 strokes in the united states and strokes kill over 150,000 americans each year. Over 15% of people who have had a stroke die within 30 days, and 15-30% of people of people who survive a stroke are permanently disabled” ("Your). “A stroke happens when a blood vessel to the brain is blocked by a clot or burst. When a blood vessels burst or breaks, it is known as a hemorrhagic stroke. This causes your brain to not get the oxygen from the blood it needs, killing brain cells. Someone in the world has a stroke every 40 seconds. More women than men have had strokes each year, in part because women live longer.”("About). According

Ischemic stroke is a prevalent and harmful disease that often results in permanent neurologic deficit. Currently, there is a dearth of therapeutic options available to improve patients’ functional recovery after stroke. A number of factors impede healing in the central nervous system, including glial scarring, a relative lack of stem cells, and growth-inhibitory proteins located in the extracellular matrix and on cell surfaces. Myelin-associated inhibitors of neurite outgrowth, found on oligodendrocytes, represent a significant obstacle to the process of cortical reorganization that occurs during recovery from infarction. Recent research has identified the mechanisms by which these inhibitors act in the setting of stroke, paving the

stroke results when arteries carrying blood to the brain may become blocked by a blood clot or plaque or they may rupture.

Introduction: Stroke is the third leading cause of death in the United States (US) and a leading cause of serious, long-term disability. Incidence of ischemic stroke is higher than hemorrhagic stroke.
