Hypertension History
Past records as in 2600 BC reported that acupuncture, venesection and bleeding by leeches were the only treatment for ‘hard pulse disease’ which was what hypertension was known as before. The vast amount of progress in the study of hypertension was faster in the earlier decade of the 19th century because many previous beliefs were rejected. The basics of the measurement of hypertension established by Hales in 1733, the description of the pathology of hypertension by Thomas young and Richard bright in 1808 and the description of the stethoscopes sounds all enabled research to grow from anecdotal to objective approaches.
In the 19th and 20th centuries, before effective pharmacological treatment for hypertension came about, the three main

Their emphasis was on chloride. However, in reducing dietary chloride they were also restricting sodium, which is probably more important in hypertension control. Their observations preceded the use of diets extremely low in salt, which became popular in the 1940s. The success of these diets stimulated the development of the thiazide diuretics. Several investigators, such as Watkin and Murphy found that the rice diet of Kempner depended on severe sodium restriction to levels as low as 20 to 30 mEq/day. Moderate salt restriction was ineffective in these patients, possibly because they all had severe hypertension. Whether moderate restriction is effective in milder forms of hypertension remains a controversial question: some investigators claim that it is whereas others claim that it is not. Several investigators of the rice and fruit diet found that the marked sodium restriction leads to a fall in BP because it reduces the extracellular fluid and plasma volume . Extracellular fluid volume was reduced about 2 litres, and plasma volume was reduced by approximately 500 ml. Edward and Dustan independently found a similar reduction of plasma and extracellular fluid volumes during treatment with thiazide diuretics. This suggests that the antihypertensive mechanism in both of these interventions is probably volume-dependent. It also suggests that sodium deprivation will probably not be very …show more content…
Hence there was a lack of prevention for hypertension. Moreover the lack of awareness of the major impact that uncontrolled hypertension has on the development of severe heart problems like stroke and heart attacks is why I think the number of hypertension cases was high in the past. Here you can see that even if some old treatments were quite ineffective some of them like the low salt diet led to developments of new treatments like thiazide diuretics which are still used

    The quantitative study uses mostly primary sources in the literature review. This study was published in 1998 with the literature review sources ranging from 1984-1998. Sources used in this review are studies about the proper technique for measuring blood pressure, things that affect blood pressure readings, and suggestions to help prevent symptomatic orthostatic hypotension. The literature review provides a basis for the study because it supports the claims that there is inconsistency about whether feet should be kept flat on the floor while measuring blood pressure, and whether it would skew…

    It is very important for Patient X to start a diet, quit smoking, and increase physical activity. This patient has a history of hypertension, for which he is already on medication. To reduce blood pressure, it is essential to follow a diet that is low on salt intake. One of the best diet plans for people with hypertension is DASH. “The DASH diet eating plan has been proven to lower blood pressure in studies sponsored by the National Institutes of Health”. Also, every cigarette he smokes per day will increase his blood pressure, so he needs to quit smoking as soon as possible. A lack of physical activity is another factor that is increasing his risk of hypertension. Studies show that even doing some moderate exercise regularly can significantly improve a person’s blood pressure, and put them at lower risk of hypertension.…

    According to Ronald Hamdy (2001), “The availability of effective and safe medication to reduce blood pressure has dramatically changed the impact and natural course of hypertension, enormously expanded the scope and influence of medicine, transformed the role of physicians in society, and may have been a turning point in the history of mankind.” Discovering that people have high blood pressure allows physicians to prescribe their patients with the correct medicine to treat the high blood pressure. Before the development of medications to reduce or prevent hypertension, there was very little that could be done to manage it (Hamdy, 2001). “The Kempner diet was tasteless, unappetizing, monotonous, and insipid. The only other alternative to the Kempner diet was a bilateral lumbar sympathectomy, a major procedure during that period, and one that was limited to only the relatively young and fit,” according to Hamdy.…

I would like to discuss not only the horrifying procedures that were used in this era, but also the medical breakthroughs that would come about in the progression of these hundred years.

Diuretics are basically known as a water pill, which helps remove excess sodium and water from the body. Second most common medicine for hypertension is beta blockers. Beta blockers help the heart to beat a slower pace with less force.

    The prevalence of hypertension increases with age and is higher in African American than in Whites. In comparison to whites, African Americans developed high BP at an earlier age, and it is more severe at any decade. As a result, African Americans have a higher prevalence of stroke, heart disease, and end-stage renal disease when compared with whites. In addition, African American has a higher mortality rate at every level of BP elevation compared with whites. In both rises, the prevalence is higher in less educated than in more educated people. Hypertension is more prevalent in men than in women until age, 55 after age 55 it is more prevalent in women than men. The status of hypertension control has improved considerably over the past years. Large-scale education programs provided by various organizations have increased awareness of hypertension. The percentage of patients with hypertension on medication who have their BP controlled has also improved substantially. The diagnosis of hypertension requires that elevated readings be present on at least three occasions during several weeks.…
