Hypertension, commonly known as high blood pressure, is more often found in males than in females as age increases then reverses around the age of 65. There is about 67 million of American adults that have high blood pressure, which is 31 percent, that comes down to one in every three American adults (High Blood Pressure Facts, CDC.com). Hypertension is the force of blood pushing against the walls of the arteries as the heart pumps blood. Blood pressure is determined by the amount of blood your heart pumps and the amount of resistance to blood flow in your arteries. The more blood your heart pumps and the narrower your arteries, the higher your blood pressure (“What Is High Blood Pressure, NIH.com).
There are six different types of hypertension. These include primary or essential, secondary, malignant, isolated systolic, white coat or anxiety-induced hypertension, and resistant hypertension. Essential hypertension is the type of

It affects one of the most important organs, the heart, but it also affects many other important organs in the body. Some of the organs affected by hypertension are the eyes, the kidneys, the heart, and the brain. There are a few different ways blood pressure affects the eyes. One way it affect them is when blood pressure rises, that can cause loss of visual clarity for a brief period of time but then returns to normal when blood pressure lowers. There are also more serious effects; it can lead to narrowing of the arteries and can result in complete blockage, which can cause loss of vision. Also, with it affecting the heart it can lead to some serious fatal problems such as heart failure. It leads to heart failure by making the heart work harder which increases the size of the heart. When left untreated, it will results into the left ventricle of the heart increasing in size, which will ultimately lead to congestive heart failure (Hypertension and Other Organs,
In this activity Renal Response to Altered Blood Pressure was recorded. The glomerular capillary pressure and GFR; GFR and pressure increased when both arteriole radii changes were implemented simultaneously with the low blood pressure condition. Increasing the afferent radius had a greater effect than decreasing the efferent radius because there was a greater increase in glomerular pressure.
High Blood Pressure is anything that alters in peripheral vascular resistance, heart rate, or stroke volume that affects systematic arterial blood pressure. Long term effect of high blood pressure are serious and can cause heart attacks, strokes, kidney failure, and retinal damage. Hypertension is another medical word that substitutes the meaning of high blood pressure. It is known as the “silent killer” because it does not create any symptoms. The most common reason for high blood pressure is arteriosclerosis. Arteriosclerosis is the thickening and hardening of the walls of the arteries, occurring in old age. Four control systems have a job in maintaining blood pressure. These are the arterial baroreceptor and chemoreceptors’ system, regulation of body fluid volume, the renin- angiotensin system, and vascular autoregulation. Primary hypertension mostly occurs from a defect or malfunction in some or all of these
Vicki is a 42 year-old African American woman who was recently diagnosed with hypertension. Hypertension, also know as high blood pressure is the force of blood pushing against the arteries as it flows through them. Arteries are the blood vessels that carry the oxygenated blood from the heart to the rest of the body’s tissues.
Blood pressure is a measurement of the force against the walls of your arteries as your heart pumps blood through your body. Hypertension is another term used to describe high blood pressure. This common condition increases the risk for heart disease and stroke, two leading causes of death for Americans. High blood pressure contributed to more than 362,895 deaths in the United States during 2010. Approximately 67 million persons in the United States have high blood pressure, and only half of those have their condition under control. An estimated 46,000 deaths could be avoided annually if 70% of patients with high blood pressure were treated according to published guidelines (Patel, Datu, Roman, Barton, Ritchey, Wall, Loustalot; 2014).
Hypertension is deadly and it is a silent killer, if not detected on time, it can cause severe complications to major organs in the body.
Hypertension, also known as high blood pressure is a medical condition where the arteries are constantly experiencing high blood pressure due to the force exerted on the walls of the arteries as the heart pumps blood throughout the body.
Hypertension is also known as high blood pressure about 25% of all adults have high blood pressure, normal blood pressure in an adult is measure is less than 120/80 the top number is known as systolic and the bottom diastolic any reading above this is known as hypertension. If the blood pressure is regularly high this can damage to the blood vessels kidney, heart and other parts of the body which can result in a stroke or heart attack, causes of high blood pressure may be more than one thing for example too much salt in a person’s diet, being overweight, not eating enough fruits and vegetables and other life factors like stress. It is known that doctors are not too sure of the causes but the lifestyle of a person can have an effect. As you get older you’re more at risk of getting high blood pressure (hypertension), but taking part in exercise can help reduce your changes and control your blood pressure if you have already been diagnosed with high blood pressure. Read in blood pressure “the American heart association estimates that a third of adults have a high blood pressure and that in America high blood pressure killed over 55,000 people in 2005 alone” (Davis,2013)
Hypertension also known simply as high blood pressure is a common problem related to heart disease. When a person has high blood pressure, the heart has to work harder. It also speeds up the hardening of the arteries (atherosclerosis). Although high blood pressure cannot be cured, it can be controlled with a healthy diet, exercise and if necessary medication
There are generally two categories of hypertension, primary hypertension and secondary hypertension. The causes of primary hypertension are usually unknown and it develops gradually over the years. As for secondary hypertension, the causes are mainly underlying other health problems and it develops in a sudden of time. (The Healthline Editorial Team 2013) First of all, hypertension can be related to renin-angiotensin-aldosterone system (RAAS). Renin is an enzyme secreted mainly via the juxtaglomerular apparatus of the kidney when the sodium retention and water retention are reduced in the blood. (Beevers, Lip, and O'Brien 2001) Renin will bind to a substrate which is angiotensinogen and form angiotensin I which is an inactive peptide. (Foëx and Sear 2004) After that, angiotensin I will be rapidly converted to an active peptide angiotensin II by angiotensin-converting enzyme (ACE) in lungs. As a result, vasoconstriction occurs due to presence of angiotensin II and this increases the blood pressure. Moreover, angiotensin II can stimulate the releasing of aldosterone by adrenal glands. Secretion of aldosterone raises the blood pressure by reabsorbing sodium salts and water to increase sodium and water retentions. (Beevers, Lip, and O'Brien 2001)
High blood pressure (hypertension) is a major health condition which affects many Americans. This health condition may increase the risk of cardiovascular disease and stroke. A normal blood pressure consists of systolic blood pressure divided by diastolic blood pressure, 120/80mmHg (millimeters of mercury). High blood pressure is defined as systolic pressure which is greater than 140mm Hg, and diastolic pressure which is over 90mm Hg. Hypertension influences the health outcomes of black Americans more than other races in the United States. Racial discrimination and socioeconomic status are two major factors which influence the rate of high blood pressure in the black American population.
Hypertension is defined as having an abnormally high blood pressure over 140/90. There are two primary types of hypertension. Essential hypertension is diagnosed after a doctor notices elevated blood
Blood pressure is measured by two pressures; the systolic and diastolic. The systolic pressure, the top number, is the pressure in the arteries when the heart contracts. The diastolic pressure, the bottom number, measures the pressure between heartbeats. A normal blood pressure is when the systolic pressure is less than 120mmHg and Diastolic pressure is less than 80mmHg. Hypertension is diagnosed when the systolic pressure is greater than 140mmHg and the diastolic pressure is greater than 90mmHg. The physician may also ask about medical history, family history, life style habits, and medication use that could also contribute to hypertension
The pathogenesis of hypertension is multifactorial and highly complex. There are several influential factors that control blood pressure (BP) for adequate tissue perfusion, such as vascular reactivity, circulating blood volume, blood viscosity, cardiac output, blood vessel elasticity, and neural stimulation. Increased peripheral resistance, vascular rigidity, and vascular responsiveness to stimuli are significant to the pathophysiology of hypertension. Sodium has a primary effect on blood pressure leading to excess circulating volume, affecting hypertrophy, contractility, and vascular resistance (Buttaro, Trybulski, Bailey, Sandberg-Cook, 2011).
Blood pressure (BP) refers to the amount of force that is exerted upon arterial walls via the pumping of blood from the heart.1 Blood pressure can either be categorized as hypotension (low BP), normotension (Normal BP) or most important clinically as hypertension (High BP). Hypertension is a multi-factorial disease that is defined by having a systolic blood pressure (SBP) of 140mmHg and/or a diastolic blood pressure (DBP) of greater than 90mmHG based on the average of two or more readings after an initial screening.2
High blood pressure affects children and their health in many ways. For example, “75 children age 10 to 18 with untreated high blood pressure performed worse on several tests of
