Question: Who is at risk for Coronary Heart Disease Risk Factors? ?
Answer: High Blood Cholesterol and Triglyceride Levels
                
Cholesterol
                
High blood cholesterol is a condition in which your blood has too much cholesterola waxy, fat-like substance. The higher your blood cholesterol level, the greater your risk of coronary heart disease (CHD) and heart attack.
                
Cholesterol travels through the bloodstream in small packages called lipoproteins. Two major kinds of lipoproteins carry cholesterol throughout your body:
                
Low-density lipoproteins (LDL). LDL cholesterol sometimes is called "bad" cholesterol. This is because it carries cholesterol to tissues, including your heart arteries. A high LDL cholesterol level raises your risk of CHD.
                
High-density lipoproteins (HDL). HDL cholesterol sometimes is called "good" cholesterol. This is because it helps remove cholesterol from your arteries. A low HDL cholesterol level raises your risk of CHD.
                
Many factors affect your cholesterol levels. For example, after menopause, women's LDL cholesterol levels tend to rise, and their HDL cholesterol levels tend to fall. Other factorssuch as age, gender, diet, and physical activityalso affect your cholesterol levels.
                
Healthy levels of both LDL and HDL cholesterol will prevent plaque from building up in your arteries. Routine blood tests can show whether your blood cholesterol levels are healthy. Talk with your doctor about having your cholesterol tested and what the results mean.
                
Children also can have unhealthy cholesterol levels, especially if they're overweight or their parents have high blood cholesterol. Talk with your child's doctor about testing your child' cholesterol levels.

Triglycerides
                
Triglycerides are a type of fat found in the blood. Some studies suggest that a high level of triglycerides in the blood may raise the risk of CHD, especially in women.
                
High Blood Pressure
                
"Blood pressure" is the force of blood pushing against the walls of your arteries as your heart pumps blood. If this pressure rises and stays high over time, it can damage your heart and lead to plaque buildup.All levels above 120/80 mmHg raise your risk of CHD. This risk grows as blood pressure levels rise. Only one of the two blood pressure numbers has to be above normal to put you at greater risk of CHD and heart attack.
                

                
Most adults should have their blood pressure checked at least once a year. If you have high blood pressure, you'll likely need to be checked more often. Talk with your doctor about how often you should have your blood pressure checked.
                
Children also can develop high blood pressure, especially if they're overweight. Your child's doctor should check your child's blood pressure at each routine checkup.
                
Both children and adults are more likely to develop high blood pressure if they're overweight or have diabetes.

Diabetes and Prediabetes
                
Diabetes is a disease in which the body's blood sugar level is too high. The two types of diabetes are type 1 and type 2.
                
In type 1 diabetes, the body's blood sugar level is high because the body doesn't make enough insulin. Insulin is a hormone that helps move blood sugar into cells, where it's used for energy. In type 2 diabetes, the body's blood sugar level is high mainly because the body doesn't use its insulin properly.
                
Over time, a high blood sugar level can lead to increased plaque buildup in your arteries. Having diabetes doubles your risk of CHD.
                
Prediabetes is a condition in which your blood sugar level is higher than normal, but not as high as it is in diabetes. If you have prediabetes and don't take steps to manage it, you'll likely develop type 2 diabetes within 10 years. You're also at higher risk of CHD.
                
Being overweight or obese raises your risk of type 2 diabetes. With modest weight loss and moderate physical activity, people who have prediabetes may be able to delay or prevent type 2 diabetes. They also may be able to lower their risk of CHD and heart attack. Weight loss and physical activity also can help control diabetes.
                
Even children can develop type 2 diabetes. Most children who have type 2 diabetes are overweight.
                
Type 2 diabetes develops over time and sometimes has no symptoms. Go to your doctor or local clinic to have your blood sugar levels tested regularly to check for diabetes and prediabetes.

Overweight and Obesity
                
The terms "overweight" and "obesity" refer to body weight that's greater than what is considered healthy for a certain height. More than two-thirds of American adults are overweight, and almost one-third of these adults are obese.
                
The most useful measure of overweight and obesity is body mass index (BMI).You can use the National Heart, Lung, and Blood Institute's (NHLBI's) online BMI calculator to figure out your BMI, or your doctor can help you.
                
Overweight is defined differently for children and teens than it is for adults. Children are still growing, and boys and girls mature at different rates. Thus, BMIs for children and teens compare their heights and weights against growth charts that take age and gender into account. This is called BMI-for-age percentile.
                
Being overweight or obese can raise your risk of CHD and heart attack. This is mainly because overweight and obesity are linked to other CHD risk factors, such as high blood cholesterol and triglyceride levels, high blood pressure, and diabetes.

Smoking
                
Smoking tobacco or long-term exposure to secondhand smoke raises your risk of CHD and heart attack.
                
Smoking triggers a buildup of plaque in your arteries. Smoking also increases the risk of blood clots forming in your arteries. Blood clots can block plaque-narrowed arteries and cause a heart attack.Some research shows that smoking raises your risk of CHD in part by lowering HDL cholesterol levels.
                
The more you smoke, the greater your risk of heart attack. The benefits of quitting smoking occur no matter how long or how much you've smoked. Heart disease risk associated with smoking begins to decrease soon after you quit, and for many people it continues to decrease over time.
                
Most people who smoke start when they're teens. Parents can help prevent their children from smoking by not smoking themselves. Talk with your child about the health dangers of smoking and ways to overcome peer pressure to smoke.

For more information about children and smoking, go to the U.S. Department of Health and Human Services' (HHS') Kids and Smoking Web page and the CDC's Smoking and Tobacco Use Web page.
                
Lack of Physical Activity
                
Inactive people are nearly twice as likely to develop CHD as those who are active. A lack of physical activity can worsen other CHD risk factors, such as high blood cholesterol and triglyceride levels, high blood pressure, diabetes and prediabetes, and overweight and obesity.
                
It's important for children and adults to make physical activity part of their daily routines. One reason many Americans aren't active enough is because of hours spent in front of TVs and computers doing work, schoolwork, and leisure activities.
                
Some experts advise that children and teens should reduce screen time because it limits time for physical activity. They recommend that children aged 2 and older should spend no more than 2 hours a day watching TV or using a computer (except for school work).
                
Being physically active is one of the most important things you can do to keep your heart healthy. The good news is that even modest amounts of physical activity are good for your health. The more active you are, the more you will benefit.
                
For more information, go to HHS' "2008 Physical Activity Guidelines for Americans," the Health Topics Physical Activity and Your Heart article, and the NHLBI's "Your Guide to Physical Activity and Your Heart."
                
Unhealthy Diet
                
An unhealthy diet can raise your risk of CHD. For example, foods that are high in saturated and trans fats and cholesterol raise LDL cholesterol. Thus, you should try to limit these foods.
                
It's also important to limit foods that are high in sodium (salt) and added sugars. A high-salt diet can raise your risk of high blood pressure.
                
Added sugars will give you extra calories without nutrients like vitamins and minerals. This can cause you to gain weight, which raises your risk of CHD. Added sugars are found in many desserts, canned fruits packed in syrup, fruit drinks, and nondiet sodas.
                
Stress
                
Stress and anxiety may play a role in causing CHD. Stress and anxiety also can trigger your arteries to tighten. This can raise your blood pressure and your risk of heart attack.
                
The most commonly reported trigger for a heart attack is an emotionally upsetting event, especially one involving anger. Stress also may indirectly raise your risk of CHD if it makes you more likely to smoke or overeat foods high in fat and sugar.
                
Age
                
In men, the risk for coronary heart disease (CHD) increases starting around age 45. In women, the risk for CHD increases starting around age 55. Most people have some plaque buildup in their heart arteries by the time theyre in their 70s. However, only about 25 percent of those people have chest pain, heart attacks, or other signs of CHD.
                
Gender
                
Some risk factors may affect CHD risk differently in women than in men. For example, estrogen provides women some protection against CHD, whereas diabetes raises the risk of CHD more in women than in men.
                
Also, some risk factors for heart disease only affect women, such as preeclampsia, a condition that can develop during pregnancy. Preeclampsia is linked to an increased lifetime risk of heart disease, including CHD, heart attack, heart failure, and high blood pressure. (Likewise, having heart disease risk factors, such as diabetes or obesity, increases a womans risk of preeclampsia.)
                
Family History
                
A family history of early CHD is a risk factor for developing CHD, specifically if a father or brother is diagnosed before age 55, or a mother or sister is diagnosed before age 65.
