Factors leading to Coronary Heart disease

Extracts from this document...

Introduction

Factors leading to Coronary Heart disease Coronary heart disease is the leading single cause of death. It took the lives of over 135,000 people in the UK, in 1998. One in four men and one in five women die from the disease. Coronary heart disease by itself is the most common cause of death in Europe: accounting for nearly two million deaths in Europe each year. Over one in five women (22%) and men (21%) die from the disease. In the European Union, coronary heart disease is also the most common single cause of death, with over 600,000 deaths every year. The narrowing of the coronary arteries (in the heart) that feed the heart causes coronary Heart disease. Like any muscle, the heart needs a constant supply of oxygen and nutrients, which are carried to it by the blood in the coronary arteries. When the coronary arteries become narrowed or clogged by cholesterol and fat deposits a process called atherosclerosis. And are not able to supply enough blood to the heart, the result is coronary heart disease (CHD). If not enough oxygen-carrying blood reaches the heart, you may experience chest pain called angina. Sometimes this inadequate blood supply may cause no symptoms this is a condition called silent angina. ...read more.

Most of your body's fat is in the form of triglycerides stored in fat tissue. Only a small portion of your triglycerides is found in the bloodstream. High blood triglyceride levels alone do not necessarily cause atherosclerosis. But some lipoproteins that are rich in triglycerides also contain cholesterol, which causes atherosclerosis in some people with high triglycerides and high triglycerides are often accompanied by other factors (such as low HDL or a tendency toward diabetes) that raise heart disease risk. So high triglycerides may be a sign of a lipoprotein problem that contributes to heart disease. Your blood cholesterol level is affected not only by what you eat but also by how quickly your body makes LDL-cholesterol and disposes of it. In fact, your body makes all the cholesterol it needs, and it is not necessary to take in any additional cholesterol from the foods you eat. Patients with heart disease or those who are at high risk for developing it typically have too much LDL-cholesterol in their blood. Many factors help determine whether your LDL-cholesterol level is high or low. The following factors are the most important: Heredity. Your genes influence how high your LDL-cholesterol is by affecting how fast LDL is made and removed from the blood. ...read more.

Conclusion

Inactivity, together with a poor diet, is leading to rising rates of overweight and obesity, increasing the risk of chronic diseases in later life, including coronary heart disease. The advantage of getting high blood pressure and diabetes is three times higher among overweight people, than among those of normal body weight.

Only a small proportion of adults and children eat the recommended daily intake of five fruit and vegetables. It is also estimated that 36% of deaths is due to lack of physical activity, which could be avoided if people who are not exercising enough or not at all increased it to a moderate level.
