Can heart disease be prevented?

Extracts from this document...

Introduction

Can heart disease be prevented? Preventing heart disease. Something our doctors tell us about all the time, something we all want to do, but what exactly is a "heart disease". How can we prevent it if we don't even know what it is? Every one has heard the terms "heart attack" and "stroke" but hardly anyone knows what they mean. Let's start right at the beginning. A heart disease, medically known as cardiovascular disease, is a disease of the heart and the blood vessels. Most people think only the middle aged and elderly get such diseases but no, cardiovascular diseases can be found in children as young as the age of seven years old. This is strongly liked with the children's lack of exercise and a poor diet. There are many types of cardiovascular diseases of which the major ones are atherosclerosis, coronary, rheumatic, congenital, myocarditis, angina and arrhythmia. Heart disease can arise from congenital defects, infection, narrowing of the coronary arteries, high blood pressure, or disturbances. (1) Atherosclerosis is the thickening of the inner layer of the arterial walls due to the deposit of cholesterol, fibrous tissue, dead muscle cells and blood platelets. ...read more.

Middle

The coronary arteries narrow due to the formation of atheromas, these can reduce or even block the blood supply to the heart muscle, causing symptoms ranging form mild chest pain to a full heart attack. CHD comes in two main forms: heart attack (medically known as a myocardial infarction) and angina. Angina is a pain in the chest brought on by exercise or emotion. It can be mild or severe and generally lasts less than 10 minutes. A heart attack causes similar pain but lasts longer and can be fatal. Angina is caused by a narrowing of the blood vessels to the heart muscle. A heart attack results when one of those vessels is entirely blocked by a blood clot. The early deaths of well-known runner Jim Fixx and basketball star Pete Maravich made a lot of people fatalistic about prevention. "If athletes like that die early, what chance do I have of preventing heart disease?" they reasoned. (5). But giving it a closer look Jim Fixx had a genetic heart condition, which killed his father at an even earlier age, and with his healthy lifestyle probably added himself those extra years. ...read more.

Conclusion

Cholesterol is transported by lipoproteins. There are two types of lipoprotein, low-density lipoprotein (LDL), also known as "bad" cholesterol as it is deposited in the walls of the blood vessels accelerating atherosclerosis and increasing the risk of CHD and high-density lipoprotein (HDL), also known as "good" cholesterol, protects the arteries from bad cholesterol buildup, so the higher the HDL, the better. As with blood pressure, eating a low-fat, low-cholesterol diet and engaging in physical activity can lower cholesterol levels. (1) Exercising lowers the blood pressure, keeps the blood cholesterol low and improves the heart function. It is recommended to get 30 minutes of moderate physical activity most, preferably all, days of the week. (1) These 30 minutes don't have do be done all at once but can be broken down into 10 minute periods and nicely spread over the day. "Exercising is like taking the pennies from under the couch cushions and putting them into your piggybank," says Ann Bolger, M.D., a spokeswoman for the American Heart Association (AHA) and a cardiologist in San Francisco. "Every little bit counts." (1) Sticking to a nutritious, well balanced diet will greatly reduce the risk of getting a heart disease. A heart-healthy diet means a diet that's low in fat, cholesterol, and salt, and high in fruits, vegetables, grains, and fiber. ...read more.

Response to the question

'Can heart disease be prevented?' Overall surface level analysis. The response to the question is attempted at analyzing a variety of different contributory factors and ways heart disease can be prevented, but the essay format is quite disjointed and does not flow very well. To increase the level the candidate could also include diagrams or tables to ease the continuation of paragraphs and increase line spacing to make it easier to read. Also, no conclusion is provided and the introduction could be a lot more focused towards the question.

Level of analysis

Introduction does not directly address the question but is in a discussion type format. It should really provide an introduction into the main topics that will be covered in the essay. Discussion type format is not really appropriate for an essay, and the text could be made a lot more concise and to the point without it. Rather than listing a few different related effects which may lead to heart disease, the candidate should explore the different ones and how they are interlinked. The different paragraphs which do explore the effects are not effectively linked together and appear rather disjointed rather than flowing. Different scientific terms and concepts explained are very scientifically correct and show a high level of understanding. Essay appears incomplete and no conclusion is provided. References are referenced which is not normally seen in scientific A level essays, but the referencing is inconsistent. The different levels of analysis used are to a good depth.

Quality of writing

Punctuation, grammar and spelling are all to a good standard.
