NINE STEPS TO A HEALTHIER HEART.Here's our simplified version of the "Quick Desk Reference" for physicians published by the National Cholesterol Education Program The National Cholesterol Education Program is a program managed by the National Heart, Lung and Blood Institute, a division of the National Institutes of Health. Its goal is to reduce increased cardiovascular disease rates due to hypercholesterolemia (elevated cholesterol (NCEP NCEP National Cholesterol Education Program ).(1) 1 step one Get your lipids checked. Knowing only your total cholesterol isn't enough. Unlike total cholesterol, LDL LDL - ["LDL: A Logic-Based Data-Language", S. Tsur et al, Proc VLDB 1986, Kyoto Japan, Aug 1986, pp.33-41]. ("bad") cholesterol can only be checked after a nine-to-12-hour fast. The same blood test should measure your HDL (Hardware Description Language) A language used to describe the functions of an electronic circuit for documentation, simulation or logic synthesis (or all three). Although many proprietary HDLs have been developed, Verilog and VHDL are the major standards. ("good") cholesterol and your triglycerides Triglycerides Fatty compounds synthesized from carbohydrates during the process of digestion and stored in the body's adipose (fat) tissues. High levels of triglycerides in the blood are associated with insulin resistance. . No matter how good the numbers are, you'll need a new test every five years. Here's how the NCEP rates the results:
LDL ("bad") Cholesterol (mg/dL)
under 100 Optimal
100-129 Near Optimal
130-159 Borderline High
160-189 High
190 or more Very High
Total Cholesterol (mg/dL)
under 200 Desirable
200-239 Borderline High
240 or more High
HDL ("good") Cholesterol (mg/dL)
under 40 Low
60 or more High
2 step two Get checked for heart disease and diabetes. If you already have clogged arteries or diabetes, you're at greater risk for a heart attack. That means you need to get your LDL below 100 (see Step Five). Here's what your doctor should check for: * Clinical heart disease. Signs of heart disease include having had a previous heart attack, angina pectoris (chest pain when you walk or run), or procedures to prevent a heart attack (like coronary bypass surgery Coronary bypass surgery A surgical procedure which places a shunt to allow blood to travel from the aorta to a branch of the coronary artery at a point past an obstruction. Mentioned in: Cardiac Catheterization, Thallium Heart Scan or angioplasty). * Symptomatic carotid artery carotid artery n. 1. An artery that originates on the right from the brachiocephalic artery and on the left from the aortic arch, runs upward into the neck and divides opposite the upper border of the thyroid cartilage, with the external and disease. The "symptoms" are a stroke or a TIA (1) (Telecommunications Industry Association, Arlington, VA, www.tiaonline.org) A membership organization founded in 1988 that sets telecommunications standards worldwide. It was originally an EIA working group that was spun off and merged with the U.S. (transient ischemic attack Transient Ischemic Attack Definition A transient ischemic attack, or TIA, is often described as a mini-stroke. Unlike a stroke, however, the symptoms can disappear within a few minutes. , also called a temporary or mini-stroke) that the doctor can trace to clogged carotid carotid /ca·rot·id/ (kah-rot´id) pertaining to the carotid artery, the principal artery of the neck. ca·rot·id n. (neck) arteries. * Peripheral arterial disease. If the arteries leading to your legs or feet are clogged, it can cause cramping or fatigue when you're active. People with this disease have a higher risk of heart attacks and strokes. * Abdominal aortic aneurysm abdominal aortic aneurysm A focal aortic dilation of ≥ 50% ↑ in diameter, accompanied by distension and weakened aortic wall Epidemiology Incidence is rising 12/105–1951; 36/105 . An aneurysm aneurysm (ăn`y rĭzəm), localized dilatation of a blood vessel, particularly an artery, or the heart. is a ballooning out of a
section of a blood vessel, much like a bulge in an over-inflated inner
tube. If the bulge occurs in a section of the aorta (the largest artery
in your body) that passes through your abdomen, it's called an
abdominal aortic aneurysm.* Diabetes. People with diabetes are as likely to have a heart attack as people who have already had one. Diabetics also need aggressive treatment because they are more likely to die during or soon after a heart attack than non-diabetics. 3 step three Get checked for major risk factors (other than high LDL). The more risk factors you have, the lower your LDL needs to be (see Step Five). Here are the major ones: * Cigarette smoking. * High blood pressure. You have high blood pressure (hypertension) if you have a systolic blood pressure Systolic blood pressure Blood pressure when the heart contracts (beats). Mentioned in: Hypertension of at least 140 or a diastolic pressure of at least 90 or if you take medicine to lower your blood pressure. * Low HDL ("good") cholesterol. An HDL under 40 is too low. However, if your HDL is at least 60, it cancels out one of the other risk factors. * A family history of premature heart disease. If your father or brother had heart disease before age 55 or your mother or sister had it before age 65, you have this risk factor. * Age. Men aged 45 or older and women aged 55 or older have this risk factor. 4 step four Use the Framingham table (p. 7) to see if your "Ten-Year Risk" of having a heart attack is: * less than 10 percent, * 10-20 percent, or * more than 20 percent. The answer may help you with Step Five. 5 step five Use this table to find your LDL goal. The higher your risk of heart attack, the lower your LDL needs to be. Use your ten-year risk (from Step Four), your risk factors (from Step Three), and the presence of illness (from Step Two) to see how low your LDL should be. Risk Category 10-Year Risk LDL Goal (mg/dL) heart disease OR above 20% less than 100 or diabetes 2+ risk factors AND 20% or less less than 130 0-1 risk factor AND 20% or less less than 160 6 step six Use diet & exercise to lower your LDL. If your LDL is higher than your LDL goal, give yourself about 12 weeks to lower it with a diet that's low in saturated fat and cholesterol (see "Doing It With Diet," p. 8), more exercise (roughly 30 minutes a day), and weight loss (if necessary). If your LDL isn't down to the goal after six weeks, the NCEP recommends adding foods rich in soluble fiber (like oatmeal, beans, peas, and oranges) and cholesterol-lowering margarines like Benecol and Take Control. 7 step seven Consider adding drugs. If your LDL is still too high after about 12 weeks of diet and exercise, it's time to consider drugs. For most people, the first choice is a statin drug (like Zocor, Pravachol, or Lipitor). They slash LDL by 18 to 55 percent, trim triglycerides by seven to 30 percent, and bump HDL up by five to 15 percent. They protect against heart attacks and strokes and may lower the risk of diabetes, osteoporosis, and dementia. Although statins Statins A class of drugs commonly used to lower LDL cholesterol levels. Mentioned in: C-Reactive Protein carry a risk for liver abnormalities and muscle problems, both side effects are quite rare. Statins aren't the best choice for everyone. People with high triglycerides and low HDL may be better off with niacin niacin: see coenzyme; vitamin. niacin or nicotinic acid or vitamin B3 Water-soluble vitamin of the vitamin B complex, essential to growth and health in animals, including humans. or fibric acids (Lopid or Lipidil). They're more likely to have what the NCEP calls "the metabolic syndrome." Others call it "syndrome X" or insulin resistance (see March 2000, cover story). 8 step eight Find out if you have the metabolic syndrome. If you have any three of these five risk factors, you probably have the metabolic syndrome and have an increased risk of heart disease.
Risk Factor
Abdominal obesity
Men more than 40-inch waist(*)
Women more than 35-inch waist
Triglycerides (mg/dL) 150 or higher
HDL cholesterol (mg/dL)
Men under 40
Women under 50
Blood pressure (mm Hg) 130 (systolic) or higher or
85 (diastolic)or higher
Fasting blood sugar (mg/dL) 110-125
(*) In some men, a 37- to 39-inch waist can be a risk factor.
If you have the metabolic syndrome, you need to: * Treat the underlying causes (being overweight and inactive): * lose weight (if your waist is too large), and * exercise (even if you don't Even If You Don't is a single released by the band Ween in 2000 on Mushroom Records. Formats Enhanced CD single Includes the quicktime video of "Even If You Don't" directed by Matt Stone & Trey Parker of "South Park". shed a pound). * Treat the other risk factors: * lower your blood pressure (with diet or drugs), * talk to your doctor about taking aspirin (to lower the risk of blood clots that could cause heart attacks), and * lower your triglycerides. 9 step nine Find out if you have high triglycerides.
Triglycerides (mg/dL)
under 150 Normal
150-199 Borderline High
200-499 High
500 or more Very High
If your triglycerides are 150 or higher, you first need to reach your LDL goal (see Step Five), then: * lose excess weight, and * exercise more. If you reach your LDL goal and your triglycerides are between 200 and 499, you can either: * increase the close of statin stat·in n. Any of a class of drugs that inhibit a key enzyme involved in the synthesis of cholesterol and promote receptor binding of LDL cholesterol, resulting in decreased levels of serum cholesterol. or add another medication to further lower your LDL, or * take niacin or a fibrate drug to lower your VLDL VLDL very-low-density lipoprotein. ß-VLDL , beta VLDL a mixture of lipoproteins with diffuse electrophoretic mobility approximately that of ß-lipoproteins but having lower density; they are remnants derived from (very-low-density lipoprotein lipoprotein (lĭp'əprō`tēn), any organic compound that is composed of both protein and the various fatty substances classed as lipids, including fatty acids and steroids such as cholesterol. ). If your triglycerides are 500 or higher (no matter what your LDL), you first need to lower them to reduce your risk of pancreatitis (inflammation of the pancreas): * eat a very-low-fat diet (less than 15 percent of calories from fat), * lose excess weight, * exercise more, and * take niacin or a fibrate drug. Very few people have low HDL and not high triglycerides. If you're one of them, you first need to reach your LDL goal (see Step Five), then: * exercise more, * lose excess weight, and * consider taking statins, niacin, or a fibrate drug, depending on your triglycerides and your other risk factors.
