Coronary Heart Disease

Extracts from this document...

Introduction

Coronary Heart Disease: The risks and factors The heart is a crucial muscle in the body, it pumps on average five litres of blood a minute around the body. The heart itself has its own blood supply from a network of blood vessels on the surface of the heart known as the coronary arteries. Coronary Heart Disease (CHD) is formed when the supply of blood to the heart is blocked off due to the build up of fatty substances in these coronary arteries. CHD has numerous causes and thus it is the UK's biggest killer with approximately 300,000 people having a heart attack each year. Cholesterol is one of the four main causes of CHD, it is made in the liver from saturated fats and is carried through the blood stream by lipoproteins. There are also many different types of lipoproteins, but the main two are low density lipoproteins (LDL) ...read more.

Middle

Hypertension, more commonly known as high blood pressure puts strain on your heart, and increases your risk of heart disease, heart attack and stroke. By having high blood pressure the heart has to work harder in forcing the blood against the high pressure. Consequently the heart has to work harder giving people more of a risk of CHD. Diabetics also share this risk, especially those with type II diabetes. Diabetes occurs when the body can't produce a lot or even any insulin in the body. Insulin is the hormone that's needed to control the amount of glucose (sugar) in the body. Without it the high levels of sugar in the blood cause micro vascular damage (damage to the really small capillaries) in the brain and heart region, which increases the risk of CHD. Many people know smoking is bad for you, however many suspect that's it is just the lungs which suffer, although your heart suffers as well. ...read more.

Conclusion

With the high increase of obesity in the UK, many are now being told to be physically active due to the huge difference regular exercise makes on the heart. Exercise burns calories, helps control cholesterol levels, diabetes and even lowers blood pressure. But more importantly it strengthens the heart muscle, and makes the arteries more flexible, lowering the risk of CHD dramatically if exercise is done regularly. The most common contribution to CHD is stress. Everyone suffers stress, usually daily due to their profession or even their home life. During stress your nervous system releases hormones which raise your blood pressure and injure the inner linings of the arteries. When the body heals the arteries, the walls harden or sometimes thicken making it easier for cholesterol to form inside the arteries. Stress even stimulates the process of blood clotting, which combined with the release of hormones and there damage to arteries really makes a huge difference to the risk of forming CHD. * http://www.nhsdirect.nhs.uk/articles/article.aspx?articleId=444&sectionId=5 * http://www.heartd.org/coronaryheartdisease.php * Parents (doctors) ?? ?? ?? ?? ...read more.

Response to the question

The candidates response to the question is fairly explicit. They discuss many different factors that contribute to increased risk of coronary heart disease and give some information about the heart. Although the introduction to this essay is all right, I would suggest it could be better by just giving a simple explanation of what coronary heart disease is and also include what the candidate planed to discuss in the rest of the essay. It’s not necessary at this point to discuss how much blood is pumped around the body or the number or cases of CHD in the UK. Sometimes it is easier to write your introduction last if you are writing it on a computer, that way you know what the rest of essay goes on to discuss.

Level of analysis

Some of the information the candidate provides is a little brief, you need to go into as much detail as possible and make sure that you’re describing details in a way that anybody could understand. In addition the candidate uses the term heart attack, though this technically correct, at this level of qualification I would expect to see more scientific names and terms, in this case it is more appropriate to use the phrase myocardial infarction. To achieve a higher grade it is essential to go beyond the main topic of the essay, in this case the candidate could have gone on to discuss other heart diseases or even described in more detail the way in which the heart works. I also think it would have been sensible to define what is meant by a risk factor as they candidate goes on to discuss the various risks associated with CHD. This shows a board subject knowledge and can make the essay more interesting to read. Finally there is no real conclusion to this essay. A conclusion should summarise your key points and ideas (in this case the main risk factors linked to CHD). This is important as it brings the essay to a close and gives you a chance to leave the reader with a good impression.

Quality of writing

The quality of writing is poor and the language and vocabulary used is more simplistic than that expected form a candidate at this level of qualification. On a positive note, the essay is easy to read and there does not appear to be any issue with spelling, grammar or punctuation.
