Know Your NumbersWhy should I know my numbers?Your risk for heart disease and stroke can be assessed by knowing your numbers for body composition, cholesterol, triglycerides, blood pressure and blood sugar and by understanding what they mean. Body composition testsYour body is made up of water, fat, protein, carbohydrates, and various vitamins and minerals. If you have too much fat -- especially in your waist area -- your risk for heart disease and stroke is higher. Body mass indexBody mass index (BMI*) is a of a person's weight to height. BMI is commonly used to classify weight as "healthy" or "unhealthy."
*BMI may not be the most appropriate indicator to determine health status for certain groups of people. Waist circumferenceThe waist circumference is a simple measurement around a person’s natural waist (just above the navel). A high-risk waistline is defined as more than 35 inches (88 cm) for women, and more than 40 inches (102 cm) for men. CholesterolCholesterol is a waxy substance found in all parts of your body. It is coated with a layer of protein to make a “lipoprotein” that can travel through the blood. There are two types of cholesterol: LDL (low density lipoprotein) carries most of the cholesterol in the blood. When there is too much in the blood, it can lead to a cholesterol buildup in the arteries. This is why LDL cholesterol is called the “bad” cholesterol. HDL (high density lipoprotein) helps remove cholesterol from the blood and helps prevent the fatty buildup. HDL cholesterol is called the “good” cholesterol. Total cholesterol

Legend: NOTE: These categories apply to adults age 20 and above. TriglyceridesTriglycerides are the chemical form in which most fat exists in food as well as in the body. They’re also present in blood plasma and, in association with cholesterol, form the plasma lipids. Triglycerides in plasma are derived from fats eaten in foods or made in the body from other energy sources such as carbohydrates. Calories ingested in a meal and not used immediately by tissues are converted to triglycerides and transported to fat cells to be stored. Excess triglycerides in plasma are called hypertriglyceridemia. It’s linked to the occurrence of coronary artery disease in some people. Elevated triglycerides may be a consequence of other diseases, such as untreated diabetes mellitus. As with cholesterol, increases in triglyceride levels can be detected by plasma measurements. These measurements should be made after an overnight food and alcohol fast.
Blood pressureBlood pressure is the force of blood as it moves through the blood vessels. If blood cannot flow easily through the vessels, the force increases. If the force is too great, you have high blood pressure. The higher (systolic) number represents the pressure while the heart is beating. The lower (diastolic) number represents the pressure when the heart is resting between beats. The systolic pressure is always stated first and the diastolic pressure second.
Legend: Blood sugarDiabetes is a metabolic disorder in which the level of glucose in the blood -- called blood sugar -- is too high. Normally, the body gets its energy from blood sugar, which comes from food. According to the American Diabetes Association, a fasting blood sugar level in people who do not have diabetes should be between 60 - 99 mg/dL. If you have diabetes, your goal for blood sugar levels using a blood glucose meter should be-
Your blood sugar goals may be different from these ideal goals. Ask your health care provider what goals are best for you. For a healthy heart, try to live by these numbers:
