 How to prevent Coronary Heart Disease Risk Factors ? 
 You can prevent and control many coronary heart disease (CHD) risk factors with heart-healthy lifestyle changes and medicines. Examples of risk factors you can control include high blood cholesterol, high blood pressure, and overweight and obesity. Only a few risk factorssuch as age, gender, and family historycant be controlled.
                
To reduce your risk of CHD and heart attack, try to control each risk factor you can. The good news is that many lifestyle changes help control several CHD risk factors at the same time. For example, physical activity may lower your blood pressure, help control diabetes and prediabetes, reduce stress, and help control your weight.
                
Heart-Healthy Lifestyle Changes
                
A heart-healthy lifestyle can lower the risk of CHD. If you already have CHD, a heart-healthy lifestyle may prevent it from getting worse. Heart-healthy lifestyle changes include:
                
Heart-healthy eating
                
Maintaining a healthy weight
                
Managing stress
                
Physical activity
                
Quitting smoking
                
Many lifestyle habits begin during childhood. Thus, parents and families should encourage their children to make heart-healthy choices, such as following a healthy diet and being physically active. Make following a healthy lifestyle a family goal. Making lifestyle changes can be hard. But if you make these changes as a family, it may be easier for everyone to prevent or control their CHD risk factors.

Heart-Healthy Eating
                
Your doctor may recommend heart-healthy eating, which should include:
                
Fat-free or low-fat dairy products, such as skim milk
                
Fish high in omega-3 fatty acids, such as salmon, tuna, and trout, about twice a week
                
Fruits, such as apples, bananas, oranges, pears, and prunes
                
Legumes, such as kidney beans, lentils, chickpeas, black-eyed peas, and lima beans
                
Vegetables, such as broccoli, cabbage, and carrots
                
Whole grains, such as oatmeal, brown rice, and corn tortillas
                
When following a heart-healthy diet, you should avoid eating:
                
A lot of red meat
                
Palm and coconut oils
                
Sugary foods and beverages
                
Two nutrients in your diet make blood cholesterol levels rise:
                
Saturated fatfound mostly in foods that come from animals
                
Trans fat (trans fatty acids)found in foods made with hydrogenated oils and fats, such as stick margarine; baked goods, such as cookies, cakes, and pies; crackers; frostings; and coffee creamers. Some trans fats also occur naturally in animal fats andmeats.
                
Saturated fat raises your blood cholesterol more than anything else in your diet. When you follow a heart-healthy eating plan, only 5 percent to 6 percent of your daily calories should come from saturated fat. Food labels list the amounts of saturated fat. To help you stay on track, here are some examples:
                
1,200 calories a day
                
8 grams of saturated fat a day
                
1,500 calories a day
                
10 grams of saturated fat a day
                
1,800 calories a day
                
12 grams of saturated fat a day
                
2,000 calories a day
                
13 grams of saturated fat a day
                
2,500 calories a day
                
17 grams of saturated fat a day
                
Not all fats are bad. Monounsaturated and polyunsaturated fats actually help lower blood cholesterol levels.
                
Some sources of monounsaturated and polyunsaturated fats are:
                
Avocados
                
Corn, sunflower, and soybean oils
                
Nuts and seeds, such as walnuts
                
Olive, canola, peanut, safflower, and sesame oils
                
Peanut butter
                
Salmon and trout
                
Tofu
                
Sodium
                
You should try to limit the amount of sodium that you eat. This means choosing and preparing foods that are lower in salt and sodium. Try to use low-sodium and no added salt foods and seasonings at the table or while cooking. Food labels tell you what you need to know about choosing foods that are lower in sodium. Try to eat no more than 2,300 milligrams of sodium a day. If you have high blood pressure, you may need to restrict your sodium intake even more.
                
Dietary Approaches to Stop Hypertension
                
Your doctor may recommend the Dietary Approaches to Stop Hypertension (DASH) eating plan if you have high blood pressure. The DASH eating plan focuses on fruits, vegetables, whole grains, and other foods that are heart healthy and low in fat, cholesterol, and sodium and salt.
                
The DASH eating plan is a good heart-healthy eating plan, even for those who dont have high blood pressure. Read more about DASH.
                
Alcohol
                
Try to limit alcohol intake. Too much alcohol canraise your blood pressure and triglyceride levels, a type of fat found in the blood. Alcohol also adds extra calories, which may cause weight gain.
                
Men should have no more than two drinks containing alcohol a day. Women should have no more than one drink containing alcohol a day. One drink is:
                
12 ounces of beer
                
5 ounces of wine
                
1 ounces of liquor
                
Maintaining a Healthy Weight
                
Maintaining a healthy weight is important for overall health and can lower your risk for coronary heart disease. Aim for a Healthy Weight by following a heart-healthy eating plan and keeping physically active.
                
Knowing your body mass index (BMI) helps you find out if youre a healthy weight in relation to your height and gives an estimate of your total body fat. To figure out your BMI, check out NHLBIs online BMI calculator or talk to your doctor. A BMI:
                
Below 18.5 is a sign that you are underweight.
                
Between 18.5 and 24.9 is in the normal range.
                
Between 25 and 29.9 is considered overweight.
                
Of 30 or more is considered obese.
                
A general goal to aim for is a BMI of less than 25. Your doctor or health care provider can help you set an appropriate BMI goal.
                
Measuring waist circumference helps screen for possible health risks. If most of your fat is around your waist rather than at your hips, youre at a higher risk for heart disease and type 2 diabetes. This risk may be high with a waist size that is greater than 35 inches for women or greater than 40 inches for men. To learn how to measure your waist, visit Assessing Your Weight and Health Risk.
                
If youre overweight or obese, try to lose weight. A loss of just 3 percent to 5 percent of your current weight can lower your triglycerides, blood glucose, and the risk of developing type 2 diabetes. Greater amounts of weight loss can improve blood pressure readings, lower LDL cholesterol, and increase HDL cholesterol.
                
Managing Stress
                
Research shows that the most commonly reported trigger for a heart attack is an emotionally upsetting eventparticularly one involving anger. Also, some of the ways people cope with stresssuch as drinking, smoking, or overeatingarent healthy.
                
Learning how to manage stress, relax, and cope with problems can improve your emotional and physical health. Consider healthy stress-reducing activities, such as:
                
A stress management program.
                
Meditation
                
Physical activity
                
Relaxation therapy
                
Talking things out with friends or family
                
Physical Activity
                
Routine physical activity can lower many CHD risk factors, including LDL (bad) cholesterol, high blood pressure, and excess weight. Physical activity also can lower your risk for diabetes and raise your HDL cholesterol level. HDL is the good cholesterol that helps prevent CHD.
                
Everyone should try to participate in moderate-intensity aerobic exercise at least 2hours and 30minutes per week, or vigorous aerobic exercise for 1 hour and 15 minutes per week. Aerobic exercise, such as brisk walking, is any exercise in which your heart beats faster and you use more oxygen than usual. The more active you are, the more you will benefit. Participate in aerobic exercise for at least 10 minutes at a time spread throughout the week.

Talk with your doctor before you start a new exercise plan. Ask your doctor how much and what kinds of physical activity are safe for you.
                
Quitting Smoking
                
If you smoke, quit. Smoking can raise your risk for coronary heart disease and heart attack and worsen other coronary heart disease risk factors. Talk with your doctor about programs and products that can help you quit smoking. Also, try to avoid secondhand smoke. If you have trouble quitting smoking on your own, consider joining a support group. Many hospitals, workplaces, and community groups offer classes to help people quit smoking.

Medicines
                
Sometimes lifestyle changes arent enough to control your blood cholesterol levels. For example, you may need statin medications to control or lower your cholesterol. By lowering your cholesterol level, you can decrease your chance of having a heart attack or stroke. Doctors usually prescribe statins for people who have:
                
Coronary heart disease, peripheral artery disease, or had a prior stroke
                
Diabetes
                
High LDL cholesterol levels
                
Doctors may discuss beginning statin treatment with those who have an elevated risk for developing heart disease or having a stroke.
                
Your doctor also may prescribe other medications to:
                
Decrease your chance of having a heart attack or dying suddenly.
                
Lower your blood pressure.
                
Prevent blood clots, which can lead to heart attack or stroke.
                
Prevent or delay the need for a procedure or surgery, such as percutaneous coronary intervention or coronary artery bypass grafting. 
                
Reduce your hearts workload and relieve CHD.
                
Take all medicines regularly, as your doctor prescribes. Dont change the amount of your medicine or skip a dose unless your doctor tells you to.You should still follow a heart-healthy lifestyle, even if you take medicines to treat your CHD.
