"The presence of LDL-cholesterol is an obligate for development of an atherosclerotic plaque."
Knowing the facts about cholesterol can reduce your risk for a heart attack or stroke.
Are you at risk?
Heart disease is the leading cause of death for women and men in the United States.
RISK FACTORS FOR HEART DISEASE
1. ADVANCING AGE (OVER 45 IN MEN AND 55 IN WOMEN)
2. HIGH BLOOD PRESSURE
4. FAMILY HISTORY OF HEART DISEASE
5. HIGH CHOLESTEROL OR GOOD CHOLESTEROL BEING LOW
6. DIABETES OR METABOLIC SYNDROME
7. OVERWEIGHT/INACTIVITY OR OBESITY
Heart disease is the number one preventable killer in the US. Atherosclerosis (plaque build up in arteries) is a disease of arteries that causes more death and disability than any other disease in the industrialized world, more than all types of cancer combined.
Cholesterol is a fat-like waxy substance, a steroid molecule, nearly all made by your liver. Cholesterol is essential for all your cells in your body to function properly. It may surprise you to know that cholesterol itself isn't bad. In fact, cholesterol is just one of the many substances created and used by our bodies to keep us healthy. Some of the cholesterol we need is produced naturally (and can be affected by your family health history), while some of it comes from the food we eat. However, over production or over absorption of cholesterol causes harm to your blood vessels also known as atherosclerosis. Too much cholesterol in the blood is a major risk for coronary heart disease (which leads to heart attack) and for stroke. Hypercholesterolemia is the medical term for high levels of blood cholesterol.
Since cholesterol is a fat, it does not dissolve in blood and therefore must be carried in blood by lipoproteins. Lipoproteins are large complex molecules that carry the fats around the body in the blood. The "bad" lipoproteins are called Apolipoprotein B (Apo-B), and the "good" are called Apolipoprotein A (Apo-A). ApoB is the main structural protein for LDL cholesterol particles (bad cholesterol), while ApoA is the main lipoprotein on HDL particles (good cholesterol).
The more LDL particles that are present, the quicker the atherosclerosis will occur especially when other cardiac risk factors are present. The presence of LDL cholesterol is obligate for development of an atherosclerotic plaque.
