Since Cholesterol cannot dissolve in the blood, it has to be transported via lipoproteins to and from the cells. There are two types of Cholesterol. One is called LDL (bad) Cholesterol, and the other is called HDL (good) Cholesterol. Your total Cholesterol count is made up of the LDL type, HDL type and then you add Lp(a) Cholesterol and triglycerides. The total count is done through a simple blood test.
The LDL bad Cholesterol is the one that builds up in the artery walls becoming plaque which is usually a thick deposit that narrows the arteries so the blood flow is inhibited. The plaque may be soft or hard, and may be more or less volatile depending upon the circumstances of the buildup.
HDL good Cholesterol creates heart protection, if the levels are high enough. If your HDL levels are low, it increases the likelihood of both heart disease, and heart attacks. Research tends to indicate that HDL good Cholesterol carries excel cholesterol away from the heart arteries. This slows the buildup or can if high enough, and of a certain type stops the buildup completely. |
