Factors affecting the development of a Coronary Heart Disease.

Extracts from this document...

Introduction

Factors affecting the development of a Coronary Heart Disease A coronary heart disease (CHD) is a disease of the arteries that supply blood to the heart muscle, causing damage to the heart. It happens when the arteries become narrow or blocked, wither stopping or reducing the amount of blood flow to the heart. About 300,000 (quote from http://www.doh.gov.uk/nsf/coronary.htm) people have heart attacks every year, and more than 110,000 in England (quote from http://www.doh.gov.uk/nsf/coronary.htm) die from a CHD every year. CHD is much more common in deprived areas, as treatment and care is often more readily available in more wealthy areas. CHD accounts for one third of all deaths in people aged between 45 and 64 (quote from Complete Family Health Encyclopedia) in the UK. The main risk factors that contribute towards the development of a CHD come under one of two categories; factors you can avoid, and factors that you cannot avoid. Factors that can be prevented may be such things as smoking, high blood cholesterol, high blood pressure, obesity, inactivity and high stress levels. ...read more.

will occur. This can be fatal. Smoking can also increase blood pressure due to the nicotine being a vasoconstrictor. Vasoconstriction is the name for the narrowing of arteries which will reduce the size of the lumen. This would mean the same volume of blood would need to flow through the artery, but there would be a smaller passage for it to flow through so the pressure would increase. The way in which this risk factor could be minimalised would be to stop smoking altogether. The second risk factor that contributes towards the development of a CHD would be high blood cholesterol. Cholesterol is an example of a lipid (fat). It forms lipoproteins when combined with proteins in the blood. The most common way for a CHD to form is by the build up of fatty cholesterol in the arteries, causing them to block. The average blood cholesterol level is 5.8 millimoles per litre of blood. Cholesterol is made from the saturated fats that are found in food. ...read more.

Conclusion

I have now analysed what I consider to be two of the main risk factors in the development of a coronary heart disease, however the factors can be linked together, so it may not be one single risk factor that causes the development of a CHD, rather a few of them. For example, an unhealthy diet could cause obesity which would lead to the person becoming inactive, developing high blood cholesterol which is made up from the saturated fats in your diet. Obesity also carries an increased risk of high blood pressure and diabetes mellitus. The combination of all these factors that I think contributes towards a coronary heart disease developing. These two risk factors that I have focused on are results of an unhealthy lifestyle as are many of the other factors. In general most of the risk factors can be reduced simply by maintaining a healthier lifestyle such as; a healthy balanced diet, regular exercise, no smoking or minimal passive smoking, reduce stress levels by dealing with problems rather than letting them build up (these problems can be dealt with by exercising as this is a proven stress reduction technique). ...read more.
