Hypertension is one of the most common chronic disease (Barranger, 2013). Many people are unaware of the fact that they have hypertension because they do not have any symptoms associated with this chronic disease. Hypertension can be a major risk factor for many other chronic diseases such as heart disease, stroke, congestive heart failure, and kidney disease. Hypertension is strongly associated with obesity and diabetes. Hypertension caused morbidity and mortality are the highest, occur early and more severe among African American’s (Barranger, 2013).
Essential hypertension is the most common type of hypertension (Barranger, 2013). Other types of hypertension include primary, idiopathic hypertension and secondary hypertension (when other causes can be identified) (Barranger, 2013).
The pathophysiology of hypertension involves nervous system and/or renal system (Barranger, 2013). Centrally located beta receptors and alpha-2 receptors have effects on the production of norepinephrine. The production of norepinephrine is stimulated and inhibited by these receptors. When norepinephrine production is inhibited, vasodilation effects occur, therefore blood pressure (BP) is reduced. Beta 1 receptor blockers and beta 2 receptor stimulators of the arteries and veins will decrease blood pressure by decreasing cardiac output, peripheral resistance, and causation of vasodilation. Baroreceptors can auto regulate blood pressure in the circulatory system by sending impulse to the brain
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).
Hypertension is sometimes referred to as the silent killer (Aycock, Kirkendoll, & Gordon, 2013). Today it is a public health problem. According to the American Heart Association 2013 Statistical Fact Sheet (2013), one out of every three adults has high blood pressure, which is estimated at 77.9 million people (AHA, 2013). High blood pressure is also referred to as hypertension. Hypertension is a prevalent medical condition that carries with it the risk factor for increased chances of heart disease and stroke (Gillespie & Hurvitz, 2013). Hypertension remains one of the top 10 causes of worldwide disability-adjusted life years (as cited in Drenjančević-Perić et al., 2011). For the estimated 348, 102 deaths in 2009, high blood pressure was listed as the primary or contributing cause of death (AHA, 2013). Despite the health risk associated with hypertension, the diagnoses of high blood pressure continue to rise. By 2030, hypertension is expected to increase by 7.2% from 2013 estimates (AHA, 2013).
High blood pressure (hypertension ) is defined as high pressure (tension ) in the arteries , which are the vessels that carry blood from the heart to the rest of the body . High blood pressure is considered one of the highest causes of morbidity , one of the main leading causes of cardiovascular disease , and social global burden health risk factor . In addition to the high-cost burden to the global health service providers . About 70 million American adults have high blood pressure . Only about half of people with high blood pressure have their condition under control . Nearly 1 of 3 American adults has prehypertension , blood pressure numbers that are higher than normal , but not yet in the high blood pressure range . High blood pressure
Hypertension is a very common problem, affecting 1 billion people worldwide, with 50 million cases in the United States, and one third of cases going undiagnosed. 1% of the cases will experience a hypertensive emergency in their life. (1,2)
Essential hypertension, otherwise known as primary or idiopathic hypertension, is a condition of raised blood pressure with no identifiable cause. Secondary hypertension occurs when blood pressure elevation results from a specific and potentially treatable cause. These include renal diseases, endocrine causes, congenital cardiovascular causes and pregnancy.
My mother, Nanci, my uncle, Mike, and my aunt Kim have all been diagnosed with hypertension. Hypertension, also known as high blood pressure is the most common cardiovascular disease and leads to over 326,000 deaths in the United States every year (Adams & Urban, 2013). Hypertension is consistent increased systemic arterial blood pressure, and can be divided into two categories, primary and secondary. Primary hypertension has no identifiable cause, and according to Adams and Urban is responsible for almost 90% of all cases of diagnosed hypertension (Adams & Urban, 2013). Secondary hypertension on the other hand is related to an underlying disease process or condition, such as hyperthyroidism or the use of corticosteroids. Hypertension can systemic issue, which means that the blood pressure of the entire body is affected, or it can be a localized issue where only certain tissues are affected, such as the liver. Hypertension is usually an asymptomatic issue, however, when symptoms do appear, they have been caused by the long-term existence of the disorder, over years or decades. Over time, the elevation of the blood pressure begins to wear on the arteries and the organs of
Hypertension (HT), defined as a chronic elevation of systolic and/or diastolic blood pressure (BP), is in all probability the most common chronic disease today. Clinically hypertension is not a disease at usual sense it is a risk factor for many future vascular diseases1,2. In human body blood pressure is maintained by several factors such as kidney, sympathetic nervous system, hormonal mechanisms along with the diet taken. These include lipids, magnesium, sodium, potassium and the total energy intake3.
Hypertension is a chronic condition that affects an immense amount of people across different ages, genders, ethnicities, and health statuses. With 65 million diagnosed individuals in the US, it is the most common patient motivation to visit a physician and accounts for the largest number of prescriptions written in the country.1,2 Risk factors for disease development include unpreventable circumstances such as age and genetics in addition to modifiable behaviors such as obesity, dietary sodium intake, and physical inactivity.2 Attributing a single causative agent to hypertension poses a challenge as arterial pressure is a stem from which multiple physiologic functions and systems branch. While most documented cases (more than 95%) are
Hypertension is a devastating disease state, increasing the risk for patients to develop strokes, heart attacks, heart failure, and kidney dysfunction. It is prevalent in our population with an estimated 10-15% of Americans diagnosed with hypertension (Hitner & Nagle, 2016). Hypertension is the leading cause of cardiovascular disease (CVD), which results in nearly 1/3 of deaths annually in the United States (Still, Ferdinand, Ogedegbe, & Wright, 2015). Hypertension is more likely after the age 60, and is more common in African American patients. It affects 40.4% of African Americans and only 27.4% of whites, causing the African American community to carry a higher burden of hypertension-related complications (Still et al., 2015). There is evidence that suggests some anti-hypertensive medications are more effective in the African American population, including diuretics and calcium channel blockers (Flack, Nasser, & Levy, 2011). It is important to understand how ethnicity affects hypertension medications and what medications are preferential when treating patients, especially of African American decent.
Hypertension is the most chronic medical condition that adults have. This disease affects many organs of the body including the heart, eyes, and kidney. Hypertension can increase with age, weight, and inheritance. Generally, the hypertensive population is increasing but physicians are working on various treatments to prevent and control this disease. Prescription drugs in the United States are highest to adults with hypertension than any other medical cause. Studies show that the
chronic hypertension and ischemic heart disease which are correlated with aging physiology and environmental factors. Patient’s inactive life style and obesity is also responsible for these diseases.
In classical essential hypertension both the systolic and diastolic blood pressures are high, but isolated systolic and isolated diastolic hypertension are also seen. Malignant or accelerated hypertension is associated with a rapid rise in arterial pressure and, if untreated, results in rapid end-organ damage and death(3). Obesity-related hypertension is an important public health issue. As the prevalence of obesity increases, the prevalence of hypertension with its associated CV risk will increase as well. (4)
Hypertension is widely considered to be one of the most important risk factors of cardiovascular diseases (angina, arrhythmia, etc.). It is the second leading disease that causes mortality in the world. Hypertension is the condition when there is an increase in the force of blood on the walls of vessels. It can also be defined as an arterial blood pressure that is raised above 140/90 mm Hg (systolic/ diastolic BP). Hypertension can be classified into Secondary hypertension and Essential hypertension. When specific cause is evident but heredity, and various physiological parameters play a role in increasing blood pressure is known as Essential Hypertension. Secondary Hypertension is one where the cause is known. According to WHO guidelines between 2006 and 2015, deaths due to cardiovascular diseases are expected to increase by 17% while the deaths from infectious diseases, nutritional deficiencies, maternal and prenatal conditions are projected to decline by 3%. The main causes of hypertension includes the age ,hereditary, gender, extra weight, alcohol consumption, stress life, lazy life etc.
The two major types of hypertension are primary and secondary. Primary hypertension accounts for more than 90% of all cases and has no known cause, although it is hypothesized that genetic factors, hormonal changes, and the altercations in sympathetic tone all may play a role in its development. Secondary hypertension develops as a consequence of an underlying disease or condition. The prevention and treatment of hypertension is a major public health issue. When blood pressure is controlled, cardiovascular, renal disease, and stroke may be prevented. The JCN, reported more than 122 million individuals in American are overweight or obese, consume large amounts of dietary sodium and alcohol, and do not eat adequate amounts of fruits and vegetables; less than 20% exercise regularly. Both modifiable and non-modifiable factors play a role in the development of hypertension
