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 (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 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:
Approximately 50 million people in the United States are affected by hypertension and approximately 1 billion worldwide.
The study done by Arnold et al, from the Heart Outcomes Prevention Evaluation (HOPE) study demonstrated that an angiotensin-converting enzyme inhibitor for those at high cardiovascular risk reduced the risk of development of HF, especially among those with higher baseline blood pressures, with a relative risk of 0.67.22 A sub-study of the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) assessed the relative effect of chlorthalidone, lisinopril, and amlodipine in preventing HF and revealed that diuretics are superior to calcium channel blockers in preventing HF in hypertensive individuals.23,24 Iribarren et al, demonstrated that among those with diabetes, suggesting the importance of diabetes treatment for the prevention of diastolic dysfunction progression.25 The Hong Kong diastolic heart failure study shows that in an elderly group of heart failure patients with normal EF, diuretics
No more than 2 percent of hypertensive patients can be treated surgically. There are basically four groups of drugs a physician would prescribe a hypertension patient:DiureticsThis is usually the first choice a doctor would prescribe. It helps by increasing the rate you body eliminates urine and salt. However, this can also increase your cholesterol level, make you urinate more frequently, and may cause a loss of potassium.Beta-Adrenergic BlockersThese drugs are usually prescribed if a diuretic does not help bring your blood pressure down, and sometimes are used in combination with diuretics. Beta-adrenergic blockers work by blocking the effects of adrenaline in your body.
Hypertension, also known as high blood pressure, is a continuing blood pressure reading at or above 140 mmHg systolic and a diastolic reading of 90 mm Hg or higher. Hypertension is divided into two categories primary hypertension and secondary hypertension. Primary hypertension is the most common and it is simply hypertension that does not have an identified cause. With secondary hypertension, the high blood pressure reading is being caused by some other factor that can normally be identified and controlled such as with sleep apnea (Lewis et al., 2014, p. 712).
It is often referred to as the “silent killer”. The only way to identify if you have high blood pressure is to have it measured. This can be done using a blood pressure cuff. Normal blood pressure is 120/80 mmHg. Hypertension is when you have blood pressure equal to or greater than 140/90 mmHg. If a patient has a blood pressure in between normal and high blood pressure it is considered pre-hypertension. Patients who have severe hypertension should not receive any dental treatment until it is under control. Hypertension can lead to myocardial infarctions or stokes. Dental treatment can increase blood pressure even more because of the stress involved during
Hypertension is a common health problem especially among people over age of 60 years. This disease is diagnostic when a patient blood pressure is more than 140 to 159 over 90 to 99. Blood pressure refers to the pressure that blood applies to the inner walls of the Diabetes is an endocrine system disorder that occurs when the body is unable to control or balance the amount of sugar in blood and within bodily tissues. You know that the human body is like a machine, with organ systems that are specialized in certain functions, and interact with each other to allow all vital functions to happen. For the body to stay healthy, it is essential that its internal environment is stable and balanced despite the different changes that can occur inside
Hypertension (high blood pressure) is a common worldwide condition that is often asymptomatic and often undetected. When the left ventricle contracts it forces blood up and into the aorta distributing oxygenated blood throughout the body. The arterial pressures are exerted for this to occur effectively. Pressures rise and fall in response to baroreceptors that make note of the filling and emptying chambers of the heart. Systolic pressure should measure 120 mm Hg and diastolic 80 mm Hg. The difference between
In the US, high blood pressure is second to smoking as the largest number of preventable heart ailments and stroke deaths. According to a big government-sponsored research of hypertensive patients aged 50 and above, death from heart-related causes in 2015 went down 43 percent, while heart failures declined 38 percent when patients lowered their blood pressures below 120 as against the old target of below 140.
The only way to test for hypertension is measuring the blood pressure with a sphygmomanometer, stethoscope, and a gauge. 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 has been 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
Hypertension (better known as high blood pressure) is a condition in which the blood is being forced through the walls of the arteries (a type of blood vessel) in a heavy manner for a prolonged period of time. A majority of people who have hypertension aren’t aware of it. Therefore, blood pressure should be measured frequently. Blood pressure is measured by the amount of force that the blood is pushing through the arteries. It is read by looking at two numbers, the systolic (higher number) and the diastolic (lower number). An example of a blood pressure reading is 120/80. The 120 is the systolic pressure (as the heart contracts, this is the amount of force pushed upon the blood vessels). This means that the 80 in our example is the diastolic pressure (the force when the heart relaxes). High blood pressure affects many parts of the body along with being caused by others. Thus, it is extremely important to describe in detail the heart and the systems it affects. Hypertension is a disorder which is caused by the force of blood pumping through the heart which indicates that it takes part in the cardiovascular system along with the circulatory system. The cardiovascular system is powered by the heart which is the hardest working organ in the body. Other parts of the cardiovascular system include the arteries, capillaries, veins. This system is in charge of transporting numerous items throughout the body. These items
Hypertension (or high blood pressure) is a condition that increases the chance of developing heart disease, which is the number one leading cause of death in the United States. Hypertension affects approximately 75 million adults in America, which translates to 29% of the population.1 Hypertension is a chronic condition that results with lasting blood pressure readings of 140/90 and higher and affects the cardiovascular system in the human body. The cardiovascular system is comprised of many different networks of veins, arteries, and capillaries. The heart works with these networks and pumps blood that then pushes against the walls of arteries. High blood pressure results when the arteries tighten, in which the heart has
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
