Stress The risk factors you can't control are age, gender, and family history of CHD. Many people have at least one CHD risk factor.
High cholesterol increases the risk of other conditions, depending on which blood vessels are narrowed or blocked. Some of these diseases include: Coronary heart disease The main risk associated with high cholesterol is coronary heart disease CHD.
Your blood cholesterol level has a lot to do with your chances of getting heart disease. If your cholesterol is too high, it builds up on the walls of your arteries.
Coronary heart disease; The main risk associated with high cholesterol is coronary heart disease (CHD). Your blood cholesterol level has a lot to do with your chances of getting heart disease. If your cholesterol is too high, it builds up on the walls of your arteries. Over time, this buildup is known as atherosclerosis. In this factsheet we examine the link between cholesterol and heart disease. Atherosclerosis. Atherosclerosis is a common form of heart disease, in which plaques of cholesterol and other substances (similar to small tumors) form in the artery walls and eventually restrict blood flow. However, pharmaceutical approaches to reduce heart disease risk by raising HDL levels have had disappointing results. An international research team led by Dr. Daniel J. Rader at the University of Pennsylvania aimed to gain further insights into the relationship between HDL-cholesterol (HDL-C) and cardiovascular disease.
Over time, this buildup is known as atherosclerosis. This condition causes arteries to become narrowed, and the narrowed blood vessels reduce blood flow to the heart. This can result in angina chest pain from not enough blood flow getting to the heart, or a heart attack in cases when a blood vessel is blocked completely and the heart muscle begins to die.
Stroke A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain becomes blocked or bursts. A stroke can result if the blood supply to the brain is reduced.
When stroke occurs, part of the brain cannot get the blood and oxygen it needs, so it starts to die.
Peripheral arterial disease High cholesterol also has been linked to peripheral arterial disease PADwhich refers to diseases of blood vessels that are outside the heart and brain. In PAD, fatty deposits build up along artery walls and affect blood circulation, mainly in arteries leading to the legs and feet.
The arteries of the kidney can also be affected. Type 2 diabetes Type 2 diabetes is another disease linked to high cholesterol because diabetes can affect the different cholesterol levels.
Even if blood sugar control is good, people with diabetes tend to have increased triglycerides, decreased high-density lipoprotein HDLand sometimes increased low-density lipoprotein LDL.
This increases the likelihood of developing atherosclerosis. High blood pressure High blood pressure hypertension and high cholesterol also are linked. When the arteries become hardened and narrowed with cholesterol plaque and calcium atherosclerosisthe heart has to strain much harder to pump blood through them.
As a result, blood pressure becomes abnormally high. Cleveland Clinic is a non-profit academic medical center.

This essay will be based around a health promotion activity that was carried out by 6 students, the main focus is health promotion and raising awareness of cholesterol link to CHD.
Centre for disease control and prevention (), defines cholesterol as a waxy, fat . The most commonly reported trigger for a heart attack is an emotionally upsetting event, especially one involving anger.
Stress also may indirectly raise your risk of CHD if it makes you more likely to smoke or overeat foods high in fat and sugar. Age. In men, the risk for coronary heart disease (CHD) increases starting around age Recent articles have attempted to exonerate saturated fat from its long time connection with heart disease, questioning if certain types of SFAs may have a weaker effect on raising blood cholesterol.
Butter, cheese, red meat, and full-fat dairy are high in saturated fat. These fatty deposits can increase your risk of developing conditions such as coronary heart disease, heart attack and stroke.
Statins are drugs that lower your body’s cholesterol level.
They work by reducing the production of cholesterol in the liver and therefore reduce your risk of heart disease.
In addition to being a risk factor for heart disease, being overweight can also increase your cholesterol. Losing weight can help lower your LDL, total cholesterol levels, and triglyceride levels.
