"Coronary Heart Disease is self inflicted"

Extracts from this document...

Introduction

"Coronary Heart Disease is self inflicted" Do you agree or disagree? Coronary heart disease occurs when the coronary arteries become partially blocked from, cholesterol and fat, circulating in the blood. This causes a build up inside the walls of the arteries. This only occurs if the levels of fat and cholesterol are extremely high in the blood that there is a greater chance that it will be deposited onto the artery walls. If the arteries become completely blocked, the patient will have a myocardial infarction, commonly known as a heart attack. A heart attack can cause permanent damage to the heart muscle, and can sometimes be fatal if immediate treatment is not given. There are other contributing factors other than fatty deposits which can cause coronary heart disease such as high blood pressure. The focus of this quote is that this disease is caused by the person who has contracted it. However, this statement is not totally correct because there is evidence to suggest that heart disease can occur from uncontrollable circumstances; such as gender, heredity and age. In this essay I shall evaluate both controllable and uncontrollable circumstances for someone to suffer from coronary heart disease. Obesity is one risk in which it is often brought about by the person themselves. ...read more.

Furthermore, carbon monoxide gases exhibited from cigarette smoke intoxicates the heart's consumption of oxygen because the gas reacts with the haemoglobin rather than the oxygen that is needed for respiration (7). This social activity is not derived from birth nor is it genetic. Therefore it is definitely the persons fault for getting coronary heart disease if it was from the effects of smoking. Further more, a not so obvious but very common cause for coronary heart disease is stress which a person undertakes during everyday life (1). Many doctors have recognised an occurrence in heart attacks when prior to the problem there was severe emotional trauma with the patient involved. This is because when someone is suffering from stress their blood pressure dramatically increases. This not only causes the blood vessels to stiffen due to the high hydrostatic forces but it also increases the work rate of the heart due to when your blood pressure is too high, your heart has to work much harder to pump enough blood and oxygen to your body's organs. As a result, the heart muscle stretches and thickens. In extreme cases, the heart stops functioning properly and it fails to cope with the body's demand of oxygen and can eventually fail (4). ...read more.

Conclusion

This is because when the cholesterol circulates around the body it begins from birth until death. Unquestionably, as age increases the arteries become less elastic and more cholesterol attaches itself in the process mentioned earlier in the essay (1). Therefore, the efficiency of the coronary blood vessels decreases as age increases because blood flow is restricted to supply blood to and from the heart reducing the transport of substance to allow the heart to respire (oxygen and glucose to the heart and carbon dioxide taken away as a waste gas) (2).From this it is easy to understand how it is incorrect to assume that you can get coronary heart disease just by your lifestyle. One can live a healthy life but old age can eventually cause damage the coronary arteries causing heart disease. In conclusion, from analysing the statement and researching coronary heart disease the idea of the heart disease is a self inflicted illness is only partly correct because heart disease can be from having an unhealthy or stressful lifestyle. However, there are also hereditary, gender, age and racial factors that need to be taken into consideration when working out the causes of the disease. Nevertheless, inherited traits along with environmental risks can both contribute to causing heart disease and the same symptoms. ...read more.
