Practical Prevention—Cholesterol Counts for Women and Seniors Too
Most people know that middle-aged men with high cholesterol levels are prone to heart attacks . What many people don't seem to understand is that cholesterol is just as dangerous for women and people over age 65.
In the US, coronary heart disease is the leading killer of women, as well as men. About equal numbers of both sexes contribute to the toll of over 700,000 deaths each year from heart disease. There are some differences, though. For instance, men tend to develop heart attacks earlier, while women usually don't experience them until after age 65.
Postmenopausal Changes in Cholesterol
For reasons that aren't clear, women rapidly catch up with men with respect to heart disease during menopause . At this time the ample levels of HDL (good cholesterol) that seem to protect younger women take a nosedive. Other blood fats such as triglycerides and LDL (bad cholesterol) may start to skyrocket. As a result, about 75% of women over age 55 have unhealthy levels of cholesterol as compared to only 25% of younger women. These changes at least partly explain why a woman's risk of heart attack more than doubles after menopause.
Better Care for Women and Seniors
Research suggests that cholesterol treatment is at least as effective in preventing heart disease in women and seniors as it is in younger men. Compared to men, however, women and older people less often receive treatment to lower their cholesterol. In one study of postmenopausal women with heart disease, 91% of the women had high cholesterol levels, yet less than half were being treated for it. Similarly, elevated cholesterol levels in elderly people are frequently not given the attention they deserve.
Detecting and Controlling High Cholesterol
Current guidelines recommend aggressive drug therapy and lifestyle changes for seniors, with careful attention to individual circumstances. In addition, the National Cholesterol Education Program (NCEP) advises all adults aged 20 years or older to have their cholesterol checked at least once every five years. This should include a fasting blood test for total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides.
Do you know your cholesterol levels? Have you had them tested recently? Check out the tables below to see what the normal and desirable ranges are for each type of cholesterol and triglycerides.
Less than 200 mg/dL (5.2 mmol/L) | Desirable |
---|---|
200-239 mg/dL (5.2-6.1 mmol/L) | Borderline high |
240 or higher (6.2 mmol/L) | High |
mg/dL = milligrams per deciliter (mmol/L = millimoles per liter)
Less than 100 mg/dL (2.6 mmol/L) | Optimal |
---|---|
100-129 mg/dL (2.6-3.3 mmol/L) | Near optimal/above optimal |
130-159 mg/dL (3.4-4.0 mmol/L) | Borderline high |
160-189 mg/dL (4.1-4.8 mmol/L) | High |
190 mg/dL (4.9 mmol/L) or higher | Very high |
mg/dL = milligrams per deciliter (mmol/L = millimoles per liter)
Less than 40 mg/dL (1.0 mmol/L) | Low |
---|---|
60 mg/dL or higher (1.6 mmol/L) | Desirable |
mg/dL = milligrams per deciliter (mmol/L = millimoles per liter)
Less than150 mg/dL (1.7 mmol/L) | Normal |
---|---|
150-199 mg/dl (1.7-2.2 mmol/L) | Borderline high |
200 or higher (2.3 mmol/L) | High |
500 or higher (5.7 mmol/L) | Very high |
mg/dL = milligrams per deciliter (mmol/L = millimoles per liter)
Factors That Worsen Cholesterol Risk
If you have unhealthy amounts of cholesterol or other fats in your blood, the guidelines advise treatment based on your level of risk. The most aggressive therapy is warranted for those at highest risk for heart disease, says NCEP. This includes people with the following conditions:
- Established coronary heart disease
- Hardening of the arteries
- History of a stroke or warning stroke
- Diabetes
Lifestyle changes or cholesterol-lowering drugs are also recommended if you have two or more factors that accentuate your risk. These are the factors:
- Age: Men over 45 and women over 55
- Cigarette smoking
- High blood pressure (even if controlled)
- HDL (good) cholesterol less than 40 mg/dL (1.0 mmol/L)
- Family history of premature heart disease (in a brother or father under age 55, or a sister or mother under age 65)
I hope you will take my advice to heart: Ask your healthcare provider about your cholesterol. It really counts—for women and men of all ages—when it comes to preventing heart disease.
