Hypertension Silent Killer. What is the most effective treatment in lowering high blood pressure?

Extracts from this document...

Introduction

Tanbir Islam 12AS2 Hypertension What is the most effective treatment in lowering high blood pressure? The Problem Research has shown that high blood pressure is the main cause of Strokes and Coronary Heart Disease. It is of the most common disorders in the UK; this can be supported by many sources such as www.nhs.uk. Hypertension is regarded as a silent killer in many developed countries as statistics show; the ?2008 overall death rate from HBP was 18.3%. Death rates were 16.5% for white males, 50.3% for black males, 15.3% for Hispanic males, 13.1% for American Indian/Alaska Native males and 14.5% for Asian/Pacific Islander males?. (http://www.heart.org/idc/groups/heart-public/@wcm/@sop/@smd/documents/downloadable/ucm_319573.pdf) Hypertension elevates the blood pressure in the arteries; which damages the artery wall by the high blood pressure exerting an extra strain on the endothelium layer. This causes an inflammatory response as the white blood cells move into the artery wall and accumulate cholesterol from the blood. The cholesterol builds up which lead to the formation of an atheroma, there is also a build up of calcium salts and fibres at the site which lead to a plaque formation on the inner wall of the artery. ...read more.

(www.ncbi.nlm.nih.gov/pubmed/11130523) Figure 2 The graph shows a positive effect of ACE inhibitors and calcium antagonist has on strokes, coronary heart disease and major cardiovascular diseases; ACE inhibitors had a risk reduction of stroke by 30% and coronary heart disease by 20% while Calcium antagonist had a greater risk reduction of strokes by 39% and any major cardiovascular disease by 28%. This indicates antihypertensive drugs a more effective treatment and more favourable as they provide additional benefits to patients and have greater risk reduction in strokes, coronary heart disease and major cardiovascular diseases. Ethical, Economic & Social Issues Hypertension occurs more in developing countries such as: India, Bangladesh and Pakistan. Government in third world countries should develop comprehensive local programmes to promote healthy eating and exercise. This is one of the most prominent ways of preventing hypertension as the general public are aware of how to prevent themselves of getting hypertension by acknowledging how much salt to intake, to exercise on a regular basis and maintain a healthy weight. One ethical issue is regarding drug trials on humans. Drug testing on humans is considered morally wrong as it breaches many ethical guidelines for example: right to withdraw and deception when considering placebo based drug trials. ...read more.

Conclusion

This data is supported by many health organisations such as; National Health Service and American Heart Association. I can put a degree of trust in the information, as I have confirmed the validity of the data by comparing the information with other sources to see if it is reliable. Exercising on a regular basis helps to lower blood pressure by strengthening the heart and the cardiovascular system. Exercising helps to reduce stress, as stress is a major cause of hypertension. Exercising also helps to reduce weight loss which gives the person an ideal healthy weight to control their blood pressure. A study on ?10 269 male Harvard graduates aged between 45 and 84 showed that the men who increased their levels of physical activity had a 23% lower mortality after 20 years than their peers who did not exercise?. (Edexcel AS Biology Student Book) Radiotherapy New research has shown ?directing short bursts of radio waves at nerves surrounding the kidney? which helps to lower blood pressure for a period between 6 months to a year. This type of treatment is used for people who failed to response to antihypertensive drugs. Using radiotherapy can cause side effects such as: tiredness, sore skin, and diarrhea etc. (http://newsroom.heart. ...read more.
