5. Monitor your cholesterol (blood lipids).
Abnormal or high blood lipids (fats) are a major contributor to cardiovascular disease. Your blood lipids include the LDL (bad cholesterol; remember as “Lousy cholesterol”), HDL (good cholesterol; remember as “Healthy cholesterol”) and triglycerides. The lower your LDL and the higher your HDL, the better your prognosis. The amount of cholesterol in your blood is determined mainly by three factors: the amount produced by the liver (this is largely genetic), the amount absorbed from the intestinal tract (some from what you eat, but a lot more from cholesterol produced by the liver and excreted into the digestive tract) and, finally, age – your cholesterol increases with age. If you are at risk, medication may be necessary to lower the LDL or to raise your HDL. The ideal ratio of total cholesterol divided by HDL cholesterol is 3.0. If higher, you might need diet as therapy. The problem with diet is that, in general, it can only decrease total blood cholesterol by about 10 percent. If you have a strong family history or elevated Lp(a) (a rare abnormal cholesterol that increases the risk), drug therapy is usually needed.
