The Good And Bad About High Cholesterol
At first, everyone, ranging from cholesterol (measured in the blood) in width. In general, people living in countries where blood cholesterol is lower, like Japan to live, lower rates of heart disease.
The countries that have very high cholesterol, such as Finland, have a very high rate of coronary heart disease. However, some populations with similar total cholesterol heart disease very different, suggesting that other factors influence the risk of coronary heart disease. Hypercholesterolemia is more common in men under 55 years and women aged 55 years. The risk of high cholesterol is known to increase with age.
Cholesterol is a waxy, fat as your body needs to function normally. Cholesterol is a natural component in cell walls or membranes everywhere in the body, including brain, nerve, muscle, skin, liver, intestine and heart.
Your body uses cholesterol to produce many hormones vitamin D and bile acids that help digest fats. Just a small amount of cholesterol in the blood to meet these needs. If you have too much cholesterol in the blood, the excess may be deposited in the arteries, including the coronary arteries (heart) arteries, where it contributes to the reduction and the bottlenecks that cause the signs and symptoms of heart disease.
Too many Americans have a high level of total cholesterol and LDL (bad cholesterol). A diet rich in saturated fats (a type of fat found mostly in foods from animals and certain oils) increased LDL more than anything else in your diet. They also eat cholesterol in the diet, although the effect of saturated fatty acids in the diet is greater than the effect of dietary cholesterol.
Trans fatty acids (processed foods and saw many “fast food”) may also increase LDL levels. Cholesterol is found only in foods of animal products. Genetic factors associated with eating too much saturated fat and cholesterol are combined, the main reasons for high cholesterol to heart attack. Reduce the amount of saturated fat and cholesterol you eat is an important step in reducing your cholesterol in the blood.
The government has set the standard for levels of LDL, so that more Americans are in the risk group included reset. coronary heart disease (CHD) is caused by cholesterol and fat deposits on artery walls of oxygen and nutrients to your heart. Like any muscle, the heart needs a constant supply of oxygen and nutrients are transported by the blood in the coronary arteries.
Festivals, which are often calcified stenosis (hardened) usually cause angina (chest pain) is. Less severe narrowing may contain unstable atherosclerotic plaques or blockages called fat. Unstable plaques can rupture, clot formation in the fluid, not blood, and heart attack.
If enough blood that carries oxygen is blocked from reaching your heart, you can create a kind of chest pain called angina pectoris experience. If the blood supply to part of the heart is completely cut off from complete blockage of a coronary artery, the result of a heart attack. This is generally good and due form to a sudden closure of the artery of a blood clot in the unstable plaque.
A simple blood test to check cholesterol levels. Simply knowing your total cholesterol is not enough. A complete lipid profile measures your LDL (low density lipoprotein [] bad cholesterol), total cholesterol, HDL (high density lipoprotein] “good”) cholesterol and triglycerides [other fats in the blood. Government guidelines say healthy adults should have this analysis every 5 years.
A total cholesterol level is desirable 200 mg / dL or lower. A desirable LDL is 100 mg / dL (130-159 is borderline high, 160 high, 190 is very high). HDL or “good” cholesterol, should be about 40 mg / dL or higher being. With HDL, the higher the number the better, and 60 mg / dL protection against heart disease.
Recent studies have shown that lowering cholesterol in people without heart disease reduces the risk of developing heart disease in the first place. This applies to people with high cholesterol and for those who have average cholesterol levels.
The Framingham Heart Study showed that high cholesterol is a risk factor for coronary heart disease (CHD). Results from the Framingham study showed that the higher your cholesterol, the greater your risk. Several studies have confirmed a direct link between high cholesterol and heart disease. The Lipid Research Clinics Coronary Primary Prevention Trial (LRC-CPPT) showed first that lowering total and LDL (bad) cholesterol reduces coronary heart disease.
A number of recent studies of cholesterol lowering with statins have clearly demonstrated that the decrease in total cholesterol and LDL-cholesterol reduces the risk of a heart attack, needing bypass surgery or angioplasty, and die of causes related to CHD.
In 1994, the Scandinavian Simvastatin Survival Study (4S) is the first study to show that humans, the class of cholesterol-lowering drugs called statins (in this case took simvastatin) reduces the risk of major coronary events (as heart attack) 34%, deaths from coronary heart disease by 42% and 30% of deaths for those of coronary heart disease and high levels of cholesterol in the blood, compared with those who received placebo ( placebo, the drug has been tested).
This is seen as secondary prevention or prevention of a second heart attack, because the study subjects with heart disease, many of whom at least one previous heart attack.
The Heart Protection Study, published in 2002, studied men and women of all age groups at high risk of heart disease, regardless of their cholesterol. Treatment with simvastatin reduced CHD events by 24%. The study led some experts recommend that anyone with a high risk of coronary heart disease benefit from statin therapy, irrespective of their blood cholesterol levels.
Ultimately, the National Health and Nutrition Examination Survey III (NHANES III) from 1988-1991, found that 26% of American adults had high levels of cholesterol in the blood, and 49% had desirable values .
