• Embolism: A clot or other material that forms within the vascular system, travels from that site, and causes blockage and ischemia in distal vessels. This occurs more commonly in the heart and lungs and can lead to hemorrhagic transformation. •…
An embolic stroke refers to the formation of a clot (or emboli) somewhere other than the brain, usually the heart. The emboli will travel in the bloodstream until it becomes lodged, this will restrict blood to the brain. Strokes can affect people of all ages. The risk of stroke increases with age and it is more common among African-Americans. Risk factors that can increase chances of stroke include, but are not limited to: diabetes, heart disease, smoking, excessive alcohol intake, and illegal drug use.…
Brown, Burton, Nazarian, and Promes (2015) along with the Agency for Healthcare Research and Quality (AHRQ) provides guidelines that support the use of t-PA for the management of acute ischemic stroke. The guidelines are based on their own reviews of evidence based studies to collect information to generate the guidelines. The objective of this study was to answer the question is t-PA safe and effective for patients with ischemic stroke if given within 3 hours of onset and also if given between 3-4.5 hours from onset. The methods used to collect the evidence were through hand-searches of published literature and searches of electronic databases. 195 articles were identified as relevant to review and analyze.…
They can either be classified as a hemorrhagic stroke or an ischemic stroke (Urden, Stacy & Lough 649). Hemorrhagic strokes, which are also termed as subarachnoid hemorrage, are normally the result of a cerebral aneurysm or arteriovenous malformation. Hypertension, smoking, alcohol and stimulant use can lead to subarachnoid hemorrhage, which are blamed for 13% of strokes (Urden, Stacy & Lough 649). Eighty five percent of strokes are ischemic strokes, where a vascular obstruction, which is caused by a clot, air, lipids or thrombi-atherosclerotic plaque rupture interrupt the blood to the brain. It is important that once the patient comes to the hospital, a history is taken, a neurologic exam is completed, and results of neuro-imaging studies are completed.…
A stroke is caused when there is an interruption of blood flow to the brain. This interruption of blood flow deprives the brain of the oxygen and glucose that it needs to function (Lewis, Dirksen, Heitkemper, Bucher, & Camera, 2011). It is essential to get a stroke patient the proper…
The blood carries nutrients and oxygen is pumped from the heart to the brain through the arteries. The faulty blood flow results in brain cells damage or death. Around 85% of strokes are ischaemic stroke as an effect of blood clot. However, the rest of 15% of strokes are haemorrhagic that could be either Intracerebral haemorrhage (ICH) a bleed within the brain or Subarachnoid haemorrhage (SAH) a bleeding on the brain caused by a ruptured blood…
Participation in physical activity can decrease the risk of recurrent stroke among stroke survivors. Stroke survivors have cited various reasons for not engaging in physical activity. Physical issues that prevent movement have been cited often among this target population. In addition, motivation is cited as a reason not to participate. Some survivors that experience physical issues still find ways to engage.…
The most common causation theory is hypertension. Hypertension is the simply the stressing of blood flow to the heart and the brain. When hypertension occurs, it can and will most likely result in a fatty substance buildup in a blood vessel away from the brain (embolic ischemic stroke) thus causing an ischemic stroke. In addition to the previous causation theory, I believe the conflict theory is also a sociological theory associated with stroke.…

A stroke is a “brain attack” that anyone and everyone is susceptible to. It occurs when blood flow to an area of the brain is restricted and the brain cells are deprived of the necessary oxygen. This results in cell death and usually a permanent disability. Strokes are one of the leading causes of disability in the United States which is unbelievable since eighty percent of them are preventable. An expert in this field is Professor David J Hanson who is Professor Emeritus of…
The leading cause of long term disability in the United States is stroke, and one American dies from stroke about every four minutes. Stroke by definition is the sudden death of brain cells due to lack of oxygen. The main types of stoke are hemorrhagic, ischemic, and a transient ischemic attack. Hemorrhagic stroke is broken in to two types, and the most common is the intracerebral hemorrhage, when an artery in the brain bursts flooding the brain with blood. The second and less common subarachnoid hemorrhage, when bleeding occurs in the area between the brain and the thin tissue that covers it.…
Lastly, a stroke can also occur the blood flow to the brain is…
Hemorrhagic strokes include bleeding in the brain, called intracerebral hemorrhage and bleeding between inner and outer layers of tissue that covered the brain, called subarachnoid hemorrhage.…
The reason is due to embolisation of stasis-induced thrombi forming in the left atrial appendage. Atrial fibrillation accounts for about 10 percent of ischaemic strokes. The risk of stroke can be estimated using the CHADS2 risk stratification system. It involves 1 point for each of congestive heart failure, hypertension, age greater than 75 years old, diabetes mellitus and 2 point for prior stroke or transient ischemic attack. Leading up to his stroke he had 1 risk factor on the scoring scale, which was his hypertension.…
The most common cause of a stroke is from atheroma, or plaque buildup on the artery wall leading to narrowing and then finally an infarction of the brain, or a stroke (VanMeter & Hubert, 2014, p. 347). The progression of an atherosclerosis, starts with damage to the endothelium of the artery (VanMeter & Hubert, 2014, p. 235). This leads to inflammation and an accumulation of lipids, and white blood cells in the (middle) muscle layer of the vessel (VanMeter & Hubert, 2014, p. 235). This leads to further inflammation and plaque buildup (VanMeter…
