The relative importance of factors that cause coronary heart disease

Extracts from this document...


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. ...read more.


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. ...read more.


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. ...read more.

Response to the 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.

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.

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.
