It is important that the type of stroke is diagnosed quickly to reduce the damage done to the brain and also to determine the right type of treatment because one treatment for one kind of stroke can be harmful to someone who has had a different kind. A number of different medications may be given at the hospital to help break up the clot and prevent the formation of new clots. For Ischemic stroke the treatment can begin with drugs to break down clots and prevent further ones from forming. Aspirin can be given, along with an injection of a tissue plasminogen activator (TPA). TPA works by dissolving clots but it needs to be injected within 4.5 hours of stroke symptoms once they have presented themselves. Hemorrhagic stroke treatment can begin with drugs being given to reduce the pressure in the brain, overall blood pressure, prevent seizures and prevent sudden constrictions of blood vessels.(http://www.mayoclinic.org/diseases-conditions/stroke/diagnosis-treatment/treatment/txc-20117296) Because strokes are life-changing events that can affect a person both physically and emotionally, temporarily or permanently. After a stroke,
Heart attacks can occur when a clot blocks blood flow to the heart, often leading to death of the affected heart muscle. Likewise, ischemic strokes happen when a blood clot becomes lodged in a blood vessel of the brain, causing neurons to die due to local hypoxia. However, heart disease can also lead to damage in other ways. Cardiovascular disease can be accompanied by high blood pressure, which forces the heart to pump more forcefully in order to deliver blood throughout the body properly. High blood pressure also significantly increases the risk of blood vessels leaking or bursting, which could cause a hemorrhagic stroke, retinopathy, or other potentially life-threatening medical problems (“What is Cardiovascular Disease?”). While one affected by these conditions can recover, cardiovascular disease can obligate major lifestyle changes and generally reduce the quality of
The most common causes of strokes are thrombosis. This is when a clot forms in one of the arteries, mostly in the carotid in the neck and the vertebral artery. The blood is thick and moves very slowly through the artery. The thrombus will form on the damaged area of the artery wall and will cut off the flow of blood to the brain. The area of the artery that is damaged is cause by arteriosclerosis. This form of
Many of the risk factors for cardiovascular disease cause problems because they lead to atherosclerosis. Atherosclerosis is the narrowing and thickening of arteries and develops for years without causing symptoms. It can happen in any part of the body. Around the heart, it is known as coronary artery disease, in the legs it is known as peripheral arterial disease. The narrowing and thickening of the arteries is due to the deposition of fatty material, cholesterol and other substances in the walls of blood vessels. The deposits are known as plaques. The rupture of a plaque can lead to stroke or a heart attack. (World Heart Federation).
Ischemic Stroke tends to occur when the artery responsible to supply oxygen rich blood to the brain becomes clotted or blocked. Another type of stroke is Hemorrhagic Stroke it occurs when an artery in the brain is rupture causing it to leak. The leaks puts too much pressure on the brains cells ,which damages them. Hemorrhagic stroke is also divided into two categories : Intracerebral hemorrhage, which is the most common type of hemorrhagic stroke , it occur when an artery in the brain bursts , flooding the surrounding tissue with blood. And subarachnoid hemorrhage, which is a lest common type of hemorrhagic stroke, it occurs when there is bleeding in the area between brain and thin tissues that covers it. Last but not least is the Transient Ischemic Attack also known as TIA or sometimes call “mini stroke” . This specific stroke is different from others major types of stroke because it occurs when the blood flow is blocked for only a short period of time (no more than five minutes).
Stroke is like a heart attack, but instead the problem is with the brain not the heart. Stroke happens when the blood that is suppose to go to the brain is blocked or reduced. When the blood supply to the brain is blocked or reduced, the brain doesn’t get enough oxygen or nutrients, which causes brain cells to die. It can also be because of smoking. Smoking creates blood clots in the artery. Stroke is the top 5 disease that caused death in the US, but for black people stroke is the top 3 disease that caused death. Stroke commonly occurs to people over the age of 65. Even though the risk of having a stroke is high over the age of 65, stroke can occur at any age. Approximately 15 million people suffer from stroke each year. 5 million of these
Stroke is often related to other genetic diseases or disorders. Stroke occurs by blood flow being interrupted to the brain by either a clot or a bleed on the brain. The brain cells die quickly if blood flow is blocked (Centers of Disease Control and Prevention, 2016a). Ischemic stroke occurs when blood flow is blocked by clots or particles (CDC, 2016a). Hemorrhagic stroke occurs when the brain has a bleed from blood vessels bursting (CDC, 2016a). Stroke can leave individuals with deficits and dependent on others for care. Stroke can cause death.
Coronary Artery Disease, also known as CAD, is the most common form of heart disease. (Heart and Stroke Foundation, 2009) Coronary Artery Disease obstructs the blood flow in vessels that provides blood to the heart which is caused by the buildup of plaque on the artery walls. (Rogers, 2011, p.87) (Heart and Stroke Foundation, 2009) Plaque is a yellow substance that consists of fat substances, like cholesterol, and narrows or clogs the arteries which prevents blood flow. (Heart and Stroke Foundation, 2009) Plaque can build up in any artery but usually favors large and medium sized arteries. (Heart and Stroke Foundation, 2009)
According to Centers for Disease Control and Prevention, it is stated that “every 40 seconds, someone in the U.S. has a stroke” (“Stroke,” 2018). Cardiovascular disease (CVD) is the leading cause of death for both men and women in the United States, which include coronary heart disease, stroke, and other related conditions. There are various modifiable and non-modifiable risk factors associated with heart disease, such as age, family history, diet, physical inactivity, high blood pressure, and more (“2016 Community Health Assessment,” 2017). About 795,000 people suffer from stroke each year and it is more common among the elderly, ages 65 years and older, in the United States (“Stroke,” 2018). The consequences of stroke can be detrimental,
A stroke can be generally be defined in two types of categories. The first and most common type of stroke is called ischemic stroke. This occurs when a blood clot (cerebral thrombosis) blocks a blood vessel in the brain. Blood flow beyond the blood clot is then
Strokes occur due to a disruption to the blood supply to an area of the brain, causing damage and problems in memory.
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

Ischemic strokes are the most common form of stroke, with around 85% of strokes being of this type. They are caused by the arteries that connect to the brain becoming blocked or narrowed, resulting in ischemia - severely reduced blood flow.
