Did you know that five simple numbers can tell you a lot about your heart health?\nBy learning your heart health numbers, you can take an important step in lowering your risk for heart disease. If you\u2019re not sure where to begin, start with a trip to your doctor\u2019s office or a local heart screening event in your community, where you can learn your numbers and find out if you\u2019re at risk.\n5 Key Heart Health Numbers\n\n1. Blood pressure\nBlood pressure is the force of your blood against your arteries. It is measured with two numbers: your systolic pressure, or the pressure of the blood against your artery walls when your heart squeezes and pumps out blood, and your diastolic pressure, or the pressure of the blood against your artery walls when your heart rests between beats. An example of a blood pressure reading is 120\/80, read as \u201c120 over 80.\u201d\nTo learn more, visit the UPMC Heart and Vascular Institute or call 1-855-UPMC-HVI (876-2484).\nWhile your blood pressure will change throughout the day, it\u2019s important to know that:\n\nIf your blood pressure is 120\/80 most of the time, it is considered normal\nIf your blood pressure is more than 120\/80 but less than 140\/90 most of the time, it is considered prehypertension\nIf your blood pressure is usually 140\/90 or higher, it is considered hypertension, or high blood pressure\n\nHigh blood pressure is a major risk factor for heart disease because it puts a strain on your heart and arteries. Over time, your heart may become weak, and your arteries may become stiff and less able to move blood throughout your body. This can lead to serious, even life-threatening problems like heart attack, heart failure, and stroke.\n2. Body mass index\nYour body mass index, or BMI, uses your height and weight to measure your amount of body fat. Having too much body fat can raise your risk for heart disease and other medical conditions, so it\u2019s good to know if yours is in a healthy range.\nYou can calculate your BMI by using this tool from the National Heart, Lung, and Blood Institute. Your BMI will fall into one of these ranges:\n\nLess than 18.5 = underweight\n18.5 to 24.9 = normal weight\n25 to 29.9 = overweight\n30 or greater = obese\n\nBeing overweight or obese raises your risk for heart disease and is linked to other serious conditions, like diabetes. Maintaining a healthy weight can benefit your health in general and goes a long way to lowering your risk for heart disease.\n3. Blood sugar level\nYour blood sugar level, also called your blood glucose level, shows the amount of sugar in your blood. Blood sugar levels change throughout the day as you eat and digest food. When you have your blood sugar tested, you\u2019ll be asked to not eat for several hours before the test, and your results will fall into one of these ranges:\n\nLess than 100 mg\/dl = normal\n100 to 125 mg\/dl = prediabetes\n126 mg\/dl or higher = diabetes\n\nIf you have diabetes, your body isn\u2019t able to make or properly use a hormone called insulin, which helps move sugar from your bloodstream into your cells, so your blood sugar level will be higher. Over time, this can damage your heart and blood vessels.\n4. Total cholesterol level\nCholesterol is a soft, waxy substance found in your blood and all of your body\u2019s cells. While you need some cholesterol to help you digest food and make hormones, too much can lead to heart disease. Your total cholesterol includes:\n\nHDL, or \u201cgood\u201d cholesterol. HDL helps take away some LDL, or \u201cbad\u201d cholesterol, from your blood.\nLDL, or \u201cbad\u201d cholesterol. LDL can cause the buildup of plaque in your blood vessels.\nTriglycerides, a type of fat. Triglycerides are also linked to plaque buildup.\n\nA simple blood test can measure your total cholesterol level, and your results will be:\n\n200 mg\/dL or lower = normal\n200 \u2013 239 mg\/dL = borderline high\n240 mg\/dL or higher = high\n\nHaving too much cholesterol in your blood cause plaque to build up in your blood vessels in a condition called atherosclerosis, or hardening of the arteries. Over time, this can make your blood vessels narrow, or even totally blocked, leading to a heart attack or stroke.\n5. HDL cholesterol level\nHDL, or high-density lipoprotein, is known as \u201cgood\u201d cholesterol because it helps take away some of the LDL from your blood. You want a higher level of HDL in your total cholesterol. For example:\n\nHDL of 60 or greater = high\nHDL of 40 or lower = low\n\nOnce you know your blood pressure, BMI, blood sugar level, total cholesterol level, and HDL cholesterol level, you can talk with your doctor about how to manage and lower your risks for heart disease and serious problems like heart attack and stroke.\nIf your numbers are in healthy ranges, your doctor can tell you how often to come back for checkups to make sure they stay that way. But if not, your doctor can suggest lifestyle changes, like eating a heart-healthy diet, getting regular physical activity, quitting smoking, and finding healthy ways to cope with stress, or give you medicines that can help you control your blood pressure, diabetes, or cholesterol.
