Dangerous Blood Vessels Research Paper

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 are the 5th leading cause of death in the US, with one person dying every 4 minutes as a result. For African Americans, stoke is the 3rd leading cause of death.(http://www.cdc.gov/stroke/facts.htm) It is estimated that About 795,000 people have a stroke each year; about one every 40 seconds - there are many medical conditions that can cause a stroke and it is estimated that 8 out of 10 strokes can be prevented. However, there are some things that cannot be controlled when you are predisposed to

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)

Although Mitral Valve Prolapse has existed for many years, there are a few facts a person should know while being diagnosed with this disease. Mitral Valve Prolapse is the most common valve abnormality in the U.S (Gillinov 517). About two to three percent of the population has Mitral Valve Prolapse (Gillinov 517). Of that percentage, very few need surgery due to a severe leak (Gillinov 326). If surgical treatment is necessary, a person receiving a non-surgical valve can most likely receive a 20 percent greater chance to live at least 1 year after treatment, compared to patients receiving medication alone (Gillinov 517). This means many people who were born or diagnosed with a valve problem can most likely be diagnosed with Mitral Valve Prolapse over any other heart valve disease. When a father or a mother has Mitral Valve Prolapse, this creates a very high chance when they have a child, the child will be born having

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

All races, ethnicity, and sex are susceptible to strokes. African Americans are at greater risk for stroke. Women are more likely to have a stroke compared to men (WebMd,

Stroke is known as, “the death of nerve cells caused by an interruption of blood flow to a region of the brain,” (Goodenough, 138). When a section of the brain is shut off, neurons cannot receive enough oxygen and glucose that they need and die. The seriousness of the stroke depends on where the interruption of blood flow took place. The destruction of neurons in certain regions of the brain can cause the, “abilities controlled by that area of the brain such as memory and muscle control are lost,” (National Stroke Association). There

There are three main types of strokes. Each type has its own cause and treatment, though they are very similar. The Ischemic stroke is what approximately 85% of strokes are. This occurs when the arteries to the brain become narrowed or blocked. Either blood clot or debris can lodge into brain arteries. A Hemorrhagic stroke occurs when a blood vessel in the brain leaks or ruptures.

According to the U.S. National Library of Medicine (NLM), (2015), mitral valve stenosis (MVS) is a heart disease in which the mitral valve does not fully open; therefore, less blood flows to the body. Ray and Chambers (2014) stated the most widely known reason for MVS worldwide is rheumatic heart disease. Severe MVS is life-threatening and can lead to heart failure if left untreated (NLM, 2015). MVS may be controlled with treatment and improved with valvuloplasty or surgery (NLM, 2015). MVS is less common in the United States due to the proper treatment of patients with streptococcal infections, but MVS is still prevalent in developing countries (NLM, 2015).

In addition, as mentioned before the American Heart Association states four types of cardiovascular diseases. Heart valve problems, arrhythmia, heart attacks and strokes are all affiliated with this deadly disease. If an individual is suffering with a heart valve problem, medication and heart valve surgery is provided. Arrhythmia is treated with medications, receiving a pacemaker and cardiac defibrillation. Heart attacks are treated also with medications, angioplasty and coronary artery bypass graft surgery to improve blood supply entering the heart muscle. Lastly, medication is provided to treat strokes. Another treatment available for strokes are undergoing a carotid endarterectomy

The heart will be weaker, unable to send blood through the body, helping the electrical rhythm to stay regular. It can be inherited from family, or developed by a disease. People with cardiomyopathy may have swelling in some body parts. They may even have heart failure or arrhythmia. Because there are four major types of cardiomyopathy, it is very important that you run tests to make a diagnosis for the correct treatment to be used. The four main types are: The most common one that weakens the walls of the heart is dilated cardiomyopathy, second most common one that makes the walls of the heart thicken is hypertrophic cardiomyopathy, the type that happens when the artery that is leading to the heart is narrowed or blocked is the ischemic cardiomyopathy and the restrictive cardiomyopathy restricts the heart from stretching and is very

Pulmonary valve stenosis is a heart problem some children are born with (congenital heart defect). This defect is a stiffening or narrowing (stenosis) of a one-way valve in the heart. It is the valve that allows blood to flow from the pumping chamber on the right side of the heart (right ventricle) into the blood vessel that carries blood to the lungs. If not enough blood is flowing through the valve, not enough oxygen will get into your child’s blood. The child’s heart will also be forced to work harder.

The World Health Organization (WHO) has estimated that stroke caused 5.7 million deaths in 2004 which accounted for 9.7% of deaths in the world [1]. Strikingly as it might be, stroke is considered to be the 4th leading cause of death among all causes, when considered separately from cardiovascular diseases, on an average every 4 minutes someone dies by a stroke [2] . According to data from the Heart Disease and Stroke Statistics reveal that 2.9% of men and 2.9% of women ≥18 years of age had a history of stroke [3]. On the other hand, in terms of disability stroke is considered to be the leading cause of long term disability in the united states with an impact of 36.5 billion dollars of direct and indirect costs in 2010 [3]. According to the American Heart Association statistics from 2012 till 2030 the total direct

The symptoms and effects of a stroke can range from barely noticeable to extremely severe and disabling, and as the brain is the control centre of the body sending signals to every other system in the body, the symptoms and effects can be wide-ranging depending on what part of the brain has been affected, the type of stroke and the extent of brain damaged which has occurred. If the stroke has occurred in the right hemisphere of the brain some symptoms and long term affects that may occur are; paralysis to the left side of the body, difficulty with spatial and perceptual abilities, trouble picking objects up, misjudging distances, difficulty dressing him/her self, frequent falls and judgement difficulty which can lead to impulsive and dangerous

Research shows that the main cause of death in the United States has been found to be cardiovascular disease. The leading type of cardiovascular disease is Coronary Artery Disease (CAD) and it accounts for the majority of these deaths. Coronary Artery disease is a type of blood vessel disorder that is included in the general category of Atherosclerosis. Atherosclerosis is often referred to as “hardening of the arteries.” (Lewis, 2011) Individuals with CAD have genetic predisposition. Familial hypercholesterolemia, meaning high cholesterol in the blood, has been linked with CAD at early ages. In majority of cases of hypercholesterolemia, clients who have angina or myocardial infarction (MI) can name a parent or sibling who has died from CAD. Individuals who have incidence of coronary artery disease are often more likely to fit the demographic of middle aged, Caucasian males. Coronary Artery disease is also present among African American, Hispanic, and Native American ethnicities. African Americans have earlier onset and African American females have a higher death rate and incidence than Caucasian women. Native Americans over the age of 35 years have mortality rates twice as high as any other American because of the modifiable risk factors that include tobacco use, hypertension, obesity, and diabetes mellitus. Gender, a non-modifiable risk factor also plays a role on the individual with coronary artery disease. Men start to exhibit signs and symptoms of CAD 10 years earlier
