The relative importance of factors that cause coronary heart disease

The relative importance of factors that cause coronary heart disease.

There are many economical, environmental and genetic factors, which contribute to heart diseases. In this section, the factors will be discussed in terms of importance.

Firstly coronary heart diseases result in myocardial infarctions or heart attacks. A myocardial infarction takes place when the blood supply to part of the heart muscle (myocardium) is cut down or prevented. This occurs when one of the coronary arteries supplying the blood to the heart becomes blocked due to a build up of deposits. These will eventually tear a rupture, causing a blood clot to form, which blocks the artery leading to a heart attack.

One major economical factor contributing to coronary heart diseases is smoking. Over half of Britain indulges in more than five cigarettes a day. This increases the risks of arteriosclerosis. Arteriosclerosis refers to the hardening or narrowing of the coronary arteries. The arteries supply the blood that carries oxygen and nutrients to the heart. However, if they become blocked by arthrosclerosis, they are unable to deliver a certain amount of blood to the heart muscle. This can result in angina and heart failures due to weakening heart muscle.

What does the smoke do ???????????????

From the journal of the American medical association. Artherosclerosis causes myocardial infarctions.

Researchers studied the implications of smoking on heart diseases over three years. They concluded that it was common in smokers by 50% than non smokers and 20% likely to develop I passive smokers. However previous smokers who smoked more than a hundred cigarettes throughout were very likely to develop artherosclerosis.

Smoking also causes blood clots inside the blood vessels resulting in thrombus and ischaemic heart diseases due to narrowed coronary arteries.

What does the smoke do ???????????????

From the journal of the American medical association. Artherosclerosis causes myocardial infarctions.

Smoking also causes blood clots inside the blood vessels resulting in thrombus and ischaemic heart diseases due to narrowed coronary arteries.

Smoking relates to a number of other factors. For example, high blood pressure. This increases the workload of the heart causing it to become larger and weaker and resulting in heart failures.

Tobacco smoke also contributes to high blood cholesterol levels. As blood cholesterol increases the risk of coronary heart diseases increases.

Environmental factors can also contribute to coronary heart diseases. If a mother catches German measles during pregnancy, this could cause defects to her unborn baby’s heart.

Coronary heart diseases can be inherited. Children are more likely to develop heart diseases if there parents have it. Also African Americans, Asian Americans, native Hawaiians and Mexican Americans are more likely to develop heart diseases than whites due to high blood pressure and consuming fatty foods. People with a strong family history of coronary heart diseases are also likely to develop it. However as these factors cannot be controlled, it is even more important to control economical factors.

Men are more likely to develop heart diseases than women. Why??????

Being overweight and having an unhealthy diet can contribute to heart diseases. The excess weight increases the strain on the heart and raises blood pressure and cholesterol levels and triglyceride levels. This can be due to eating a lot of high in fat content foods (obesity).

Diabetes why??????????

One other common factor is lack of exercise. An inactive lifestyle increases risks of developing coronary heart diseases. Exercise increases circulation and more blood is pumped to the muscles supplied by the heart. Lack of exercise reduces this. Regular moderate exercise can help lose weight, control blood cholesterol, diabetes and obesity.

Alcohol consumption can raise blood pressure and cholesterol levels causing heart failure, which lead to angina. However research has shown that people who drink moderate amounts of alcohol lower the risks of heart diseases than non drinkers.

However there are less important day to day factors, which can also contribute to coronary heart diseases. Firstly stress could be one such factor. Some scientists have noted correlations between stress and heart diseases. for example high levels of stress could lead to alcohol consumption and smoking, which in turn leads to heart diseases.

Also sex hormones seem to play a role in heart diseases.

Overall we can see that important factors such as smoking lead to inevitable factors such as blood pressure and cholesterol levels, which increase the risk of heart diseases.

Control----what can you do to contrl-----genetics cant control and talk about a healthier lifestyle.

Here's what a star student thought of this essay

Quality of writing

There is a massive gap that is not needed between the second and third paragraphs. Minor punctuation errors in places, such as commas in the wrong position. Some minor grammatical errors e.g. tear a rupture should be cause a rupture. The massive text in what does the smoke does is not necessary and looks unprofessional. Paragraphing throughout is unclear and this causes confusion to the reader. Overall communication is good.

Level of analysis

The candidate introduces what a heart attack is, and what they are going to discuss succinctly and well. They give good information about what leads to an heart attack in general terms before discussing what factors may contribute to an heart attack in the build up. The candidate analyses why smoking contributes to coronary heart disease but does not discuss this in terms of importance like their introduction claimed they would. Smoking leads on to high cholesterol without any paragraphing break as the candidate assumes that smoking causes high cholesterol without explaining it when in fact they are two separate issues. The conclusion is adequate, but it does not answer the topic as it does not rank things of relative importance, but it does make a conclusion, only simple, based on the factors discussed.

Response to question

The candidate overall talks with great scientific depth and understanding of the factors causing smoking, but should relate more each of their relate importance to answer the question better as this is not evident throughout or in the conclusion. The text in bold seems to be a sabotage of the essay rather than part of it.
