Carotid Stenosis

(Marieb and Hoehn, 2010, p 703) defined Blood Pressure (BP) as ‘the force per unit area exerted on a vessel wall by the contained blood, and is expressed in millimetres of mercury (mm Hg)’. BP is still one of the essential and widely used assessment tools in healthcare settings. Nurses generally record the arterial BP which is the forced exerted blood that flows through the arteries, to establish a baseline and to determine any risk factors. BP

The health issue that this artifact discusses is the significance of knowing and recognizing the warning signs of a stroke. The American Heart Association has made it their mission to provide unlimited health information and research in the hopes of eliminating cardiovascular diseases as well as helping society in maintaining a healthy lifestyle. “Stroke is the number 5 cause of death and a leading cause of

The purpose of arterial pressure and the pulse lab is to determine the effect of posture and exercise on systolic and diastolic pressure and the heart rate. And also in order to find the differences in the reading taken under these condition compares to the baseline reading. The Sphygmomanometer and stethoscope are used to measure the systolic and diastolic blood pressure, counting the beat on the radial artery will give the reading for pulse rate and by using the lab scribe software and IWX214, the blood pressure will be measured. In the heart, the aorta and the carotid arteries have baroreceptors and the chemoreceptors that identify the changes in arterial pressure and the changes in

The major health problem selected for this project was hypertension (Harrison et al, 2011). It is identified as a cardio vascular disease risk factor such as dementia, chronic kidney disease, coronary heart disease, and stroke (NICE, 2011). It can be missed easily, as in various instances it is asymptomatic as well as it is also known as a silent killer. The Hypertension is thought to be a disease of vascular regulation ensuing from arterial pressure control mechanisms malfunction (extracellular fluid volume, rennin-angiotensin-aldosterone system, and CNS) that results in elevation of BP by means of enhanced peripheral vascular resistance, and cardiac output. There are 2 basic hypertension types. Around 90 to 95 percent of the individuals have primary hypertension which is linked with change in lifestyle as well as needs medical treatment. On the other hand, 5-10% has secondary hypertension which is linked with various other diseases for instance pregnancy, thyroid, and renal (Haslam and James, 2005). It is estimated that around 1 in 20 adults will have increased BP of 160/100 mmHg and above that results in either more than one predisposing aspects (Gemmell et al, 2006).

The stroke from a blocked artery is called ischemia, and the ruptured artery is hemorrhagic. As time is critical after the cerebrovascular accident, lack of treatment will lead to brain cell apoptosis and neural injuries are permanent. Evaluation using brief tests of cognitive impairment includes analysis of executive functioning, memory, language, and visuospatial performance, neuropsychiatric as well as depressive symptoms (Grant and Adams, 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,

Artery coronariasLa artery disease coronary (EAC) affects more than 15 million Americans, being both the most common type of cardiovascular disease. The EAC and its complications, such as arrhythmia, angina pectoris and heart attack, are the main causes of death in the United States. The most frequent cause of EAC is a disease known as 'atherosclerosis' that occurs when forms a waxy substance within the arteries that irrigate the heart. This substance, called «plate», is composed of cholesterol, fatty, calcium and a coagulant substance called «fibrin». Identified two types of plate: plate hard and soft plate.

According to research, more than 1 in 3 individuals of the American population have some form of cardiovascular disease. Hypertension is at the forefront for being the most widespread circulatory problem in adults. This condition is distinguished by a person having consistent elevated blood pressure. Although the ranges for healthy blood pressure is different for everyone, medicine tells us that the ideal pressure should remain near 120/80 mmHg. These numbers are a representation of the force being exerted into our arterial system. The first number (Systolic) displays the amount of force upon the arterial walls while the heart beats. Whereas, the second reading (Diastolic) is a measurement of pressure while the heart is relaxed. One notably

The development of an atherosclerotic plaque is relatively a very a complicated process where Plaque rupture accounts for about 76% of fatality lead by thrombi. The evolution of atherosclerosis begins with foam cell accumulation where the macrophages accumulate within arterial wall intima, progresses to form fatty streak where further accumulation of intra and extracellular lipids, this is a potentially reversible stage (Greenland p, 2013) further atheroma/fibroatheroma forms where cholesterol and phospholipids accumulate intramurally. This is a vulnerable state as it is predisposed to spontaneous rupture by inflammation and thrombus deposition may occur. Hemodynamic changes during this stage may cause ischemia or silent infarction, if large plaque rupture total occlusion may cause myocardial infarction or sudden cardiac death. Finally a complex lesion can develop where fibro muscular tissue can be seen with repair efforts followed by repeated plaque formation, this may slowly increase in size and produce significant arterial narrowing.

American Heart Association quotes that Hypertension is an important public-health challenge worldwide. Importance should be focused on its detection, treatment control and prevention. The infectious diseases such as malaria and tuberculosis which once were the reasons for leading the causes of deaths have been replaced by non –infectious diseases which are mostly the NCD’s such as diabetes, heart diseases, and other vascular conditions. Hypertension is an important worldwide public-health challenge because of its high frequency and concomitant risks of cardiovascular and kidney disease [78][79]. Heart attacks and strokes are major–but preventable–killers worldwide. More than 80% of cardiovascular disease related deaths take place in low-and

Aortic PVW has been shown to be one of the best independent predictors of cardiovascular mortality in many populations. It has been shown to be a powerful predictor of cardiovascular death in essential hypertensive patients with end-stage renal disease where SBP or PP was not as effective [68]. It has been shown to be more effective at predicting mortality in diabetics than SBP [69]. PWV has also been proven to be the best predictors of cardiovascular mortality in large cohorts of hypertensive patients with mean age of 60±13 years [72]. PWV as a surrogate for Arterial stiffness seems therefore to have the best predictive capacities in patient mortality outcome [68-72]. Many mechanisms have been

Stroke is a world wide common disease with its occurrence depending on multiple risk factors involved, one of which is high blood cholesterol and LDL level, it is thought that lower cholesterol level decreases the incidence of cerebrovascular ischemia (doc3.pdf) which has been concluded from many clinical trials conducted for the purpose of understanding the adverse effects of statins, drugs that have been manufactured primarily for the purpose of controlling blood cholesterol level, statins are defined as a family of drugs that control and inhibit cholesterol production by acting through

Atherosclerosis, the underlying cause of coronary heart disease which can affect any artery in the body, is essentially the narrowing of arteries due to excessive build up of cholesterol-rich lipids known as plaque (Insull 2009). Once the arteries become narrow, the flow of blood will be constricted, and the amount of blood, nutrients and oxygen that are able to reach the heart are reduced. As a consequence, the heart becomes increasingly hypoxic resulting in ineffective contraction. The aftermath of narrow arteries often poses serious consequences as it has a high probability of causing heart attack, angina, or even stroke (Marieb & Hoehn 2010; Insull 2009). Despite the fact that arteries will harden naturally as people age, the rate of plaque development is determined by the number of risk factors (Insull 2009). This essay will discuss and review the procedure in which the risk factors: hypertension, abnormal level of blood lipids, and smoking took to assist in the development of atherosclerosis.

The human body is a highly complex system of organs that operates efficiently at a cellular level to ensure proper functionality and longevity of the human race. However, even the slightest changes to its operation can lead to complications. In order to better understand the human body and how it works; an understanding of the diseases it is susceptible to is necessary. The cardiovascular system, in particular, is vulnerable to debilitating disease such as aneurysms, which is a ballooning of a blood vessel, or even an embolism (when any foreign body enters the blood stream). Blood vessels include arteries, capillaries and veins and therefore these events can occur anywhere in the body (i.e. the heart or the brain). There are different types of aneurysms including saccular, fusiform and pseudo-aneurysms. Saccular aneurysms only develop on part of the vessel wall and are spherical in shape. Fusiform aneurysms are ovoid in shape and develop over the entire vessel cross section. Pseudo-aneurysms are not true aneurysms but they occur as a result of a tear in the vessel wall thus collecting the blood pooled by extravascular tissue (Group). The exact cause of an aneurysm is not known but is correlated with certain previous existing conditions. Existing conditions that may have an effect on the development of an aneurysm are inherited predispositions to this disease, lifestyles, and high blood pressure. Some individuals are predisposed to developing aneurysms if their blood

Stroke is a leading cause of fatalities worldwide, including New Zealand. Stroke Foundation of New Zealand estimates 2500 stroke-related fatalities occur annually, whereas the statistics worldwide are worse. A major stroke is sudden and mostly fatal, whereas minor stroke symptoms are primarily ignored. Artery blockage (Ischaemic stroke), artery rupture (Haemorrhagic stroke) are two types of strokes in which arterial health and properties play a vital role. Arterial stiffness is one such independent property which can be assessed by Pulse Wave Velocity (PWV). PWV can be measured at a few points where the artery is close to the skin surface, carotid artery in the neck is one of such points. As carotid artery is proximate to heart branching directly
