Blood pressure is the force applied by circulating blood upon the walls of the blood vessels. The force is dependent on the cardiac output and the blood vessels resistance. Blood pressure is presented systolic pressure/ diastolic pressure. Systolic pressure, the numerator or top number, is when the heart beats. It contracts and pushes blood through the arteries and out to the rest of your body. The normal systolic pressure reading is 120 mm Hg or below. Diastolic pressure, the denominator or bottom number, refers to the pressure in the arteries between each heartbeat, when the heart is at rest. Normal diastolic blood pressure is between 80-89 mm Hg. High blood pressure is measured by an increase in the numerator systolic and denominator …show more content…
According to the American Heart Association, they are classified as the following: “1) Pre hypertensive is 120-139/80-89. 2) Stage 1 which is 140-159/90-99. 3) Stage 2 is 160+/100+. 4) Hypertensive crisis is a medical emergency that occurs when the blood pressure is 180+/110+.” (Medical News Today, 2009) Hypertension consists of two different categories; Primary hypertension and secondary hypertension. Primary hypertension is triggered by factors that are directly lifestyle related. Causes of primary hypertension are a decrease in physical activity, high consumption of salt in the diet, intake of processed and fatty foods, and tobacco and alcohol use. Secondary hypertension is usually followed by an existing disease. An example of secondary hypertension is a chronic kidney disease that leads to secondary hypertension. Hypertension can be related to several factors. Eating a surplus of salt in your diet can contribute to hypertension. Sometimes, hypertension has no symptoms at all, also known as asymptomatic. Hypertension for a long period can eventually lead to additional problems in your organs. Long term hypertension can lead to heart failure, Aneurysm, and constricting of the blood vessels which can lead to a heart attack and possible
A normal blood pressure reading should be between 80-89 for the diastolic reading. A diastolic reading of the blood pressure being higher than 90 would be considered hypertension. A diastolic blood pressure reading below 80 is considered hypotension.
Hypertension, also known as high blood pressure, has become a major risk factor for several types of heart disease across the globe. In the United States alone, nearly 70 million adults have been diagnosed with this condition [1]. Hypertension is a condition in which arterial walls experience extreme force from blood flowing through; long-term force against artery walls will lead to more serious health problems such as stroke, renal failure, and other cardiovascular diseases [2]. If the proper steps to treat hypertension are not taken, patients have a high risk of developing atherosclerosis, a condition that causes arteries to harden significantly. Smoking, obesity, lack of physical activity, high alcohol consumption, and high sodium intake are factors that may cause an individual to be diagnosed with hypertension [3] Detection of hypertension is crucial in order to reduce the incidence of death by cardiovascular disease [1].
High blood pressure has many damaging effects on the heart. High blood pressure is known as a silent killer and if left untreated can cause serious damage to the heart. What causes high blood can differ from person to person. What causes this for some may be different with another. Genetics, diet, family history, weight, and use of salt are just some of the causes of high blood pressure. Some of the ways that high blood pressure damages the heart is through narrowing of the arteries in the heart, called arteriosclerosis, left ventricular hypertrophy, and restricted blood flow that can lead to strokes and heart attacks. High blood pressure can have damaging effects on the heart if left untreated, and can cause arteriosclerosis, left ventricular hypertrophy, and restricted blood flow that leads to strokes and heart attacks.
Hypertension is characterized as an elevation in blood pressure. A blood pressure reading consistently of 140/90 mm Hg or higher is classified as high blood pressure (Appel & Linas, 2012). Hypertension is classified as two forms and they are Essential hypertension and Secondary hypertension. Essential hypertension mainly develops through lifestyle factors such as diets high in salt or low in potassium, lack of exercise, and obesity (Appel & Linas, 2012). Secondary hypertension
Hypertension (HTN) is a chronic cardiovascular condition that is characterized by high blood pressure. The blood pressure commonly abbreviated as BP is a measure of the force exerted on the blood vessels as the blood passes through them. The amount of blood pumped and the narrowness of ones’ vessels are directly proportional to the blood pressure (Mayoclinic staff, 2014).
As discussed by Dr. Fink, hypertension is a multifactorial phenomenon. The hereditability based on twin studies suggests levels as high as 30-60%, but a familial correlation may also originate from environmental factors or lifestyle habits. Specific genetic polymorphisms that may contribute include mutations in controllers of vascular smooth muscle tone and the regulators of blood volume (Mitchell, 262). It is important to note that the genetic contribution is most often polygenic in nature and not the result of a single gene mutation. This can complicate the overall picture and prevention/treatment
As the blood is forced throughout our body, there is a pressure that is exerted on the walls of our arteries, this is known as blood pressure. We see blood pressure represented as two numbers, the systolic (top) and the diastolic (bottom) numbers. The systolic blood pressure is the heart contracting and the diastolic is the heart relaxing. A normal, healthy, blood pressure would be written as 120/80 mmHg (millimeters of mercury) or verbally expressed by most individuals as 120 over 80. Our blood pressure can vary depending on many things. When the diastolic or systolic pressure is high, or significantly and consistently above 120/80 mmHg, this is what we call hypertension. There are different stages or degrees of hypertension. Lippincott Williams and Wilkins (2010) describes the stages as the following:
Blood pressure is taken in order to assess any precautions for treatment. An elevated blood pressure between the ranges of 130-139/85-89 mmHg is known as prehypertension. Prehypertension is a health concern due to an increase risk for cardiovascular disease and organ damage if continued left untreated. Cardiovascular related events associated with prehypertension include heart failure and myocardial infarction. Prehypertension can be caused by an increased amount of stress, lifestyle changes, or can be caused by a secondary disease. Factors that can influence high blood pressure include obesity, smoking, alcohol, excessive sodium intake, lack of physical activity, and diet. Secondary diseases associated with high blood pressure include diabetes mellitus and kidney disease.
Hypertension numbers are a trigger of many heart ailments and stroke. But what are hypertension numbers? Blood strain is given as numbers, "x" over "x". The "x" is a number that symbolizes the quantity of mercury within the diagnostic instrument that measures the pressure. The highest reading is a systolic reading and the underside quantity is a diastolic reading. The systolic reading is the stress as the guts beats and the diastolic indicator is the pressure when the guts is at rest. It's these numbers that present the totally different stages of hypertension.
Hypertension is the medical term for high blood pressure. A normal blood pressure is 120/80. A blood pressure reading higher or equal to 140/90 is considered abnormally high. Elevated blood pressure means your heart is working harder than normal, putting both your heart and arteries under great strain. High blood pressure is serious business.
Such things include smoking, obesity, the lack of physical activity, too much salt, too much alcohol, stress, chronic kidney failure, thyroid problems, older age, genetics, and family history. The exact cause of high blood pressure is unknown. In some cases it is not known what is causing one to have high blood pressure. However, the following things listed above are known as contributors to high blood pressure.
One risk that both hypertension and hypotension can cause is heart disease. Hypertension increases stress into a person’s blood vessel wall. This can result as ruptures in blood vessels. Hypotension however causes the blood to transport oxygen slowly. This can result into fatigue and weakness.
There are different stages of hypertension, from pre-hypertension to stage 1 hypertension to stage 2 hypertension. Each stage of hypertension must be based on an average of two or more seated blood pressure readings completed in two or more office visits. Prehypertension is the hypertensive stage in which there is a systolic blood pressure between 120 and 139 or a diastolic pressure between 80 and 89. This type tends to be prevalent in middle-aged adults. People who are pre-hypertensive are at high risk for developing hypertension. Stage 1 hypertension is when the systolic blood pressure is between 140 and 159 or the diastolic pressure is between 90 and 99. Stage 2 hypertension is when the systolic pressure is 160 or higher or the diastolic pressure is 100 or higher. There are two main types of high blood pressure: Essential and secondary high blood pressure. Essential, or primary, high blood pressure is the most common type of high blood pressure. This type tends to develop as a person ages and is prevalent amongst middle-aged adults. Secondary high blood pressure, on the other hand, is caused by another medical condition or use of certain medicines. Secondary high blood pressure typically resolves after
With the information found with what a patient’s blood pressure is, it helps health care providers understand the state of the patient’s health. A patient’s blood pressure measures the amount of pressure exerted on arterial walls in the patient’s heart. Blood pressure is measured in two numbers: systolic and diastolic. Systolic, the number listed first in blood pressure readings, reports the amount of force exerted by the blood into the arteries during ventricular contraction.
Hypertension is defined a consistent elevation of the systolic blood pressure above 140mmHg, a diastolic pressure above 90mmHg or a report of taking antihypertensive medication. Early diagnosis and effective management of hypertension is essential because it is a major modifiable risk factor to cerebrovascular, cardiac, vascular, and renal diseases. The higher the blood pressure, the greater the risk for heart attack, heart failure, stroke, and kidney disease.
