How Is Coronary Heart Disease Treated?

Treatments for coronary heart disease include heart-healthy lifestyle changes, medicines, medical procedures and surgery, and cardiac rehabilitation. Treatment goals may include:

  • Lowering the risk of blood clots forming (blood clots can cause a heart attack)
  • Preventing complications of coronary heart disease
  • Reducing risk factors in an effort to slow, stop, or reverse the buildup of plaque
  • Relieving symptoms
  • Widening or bypassing clogged arteries

Heart-Healthy Lifestyle Changes

Your doctor may recommend heart-healthy lifestyle changes if you have coronary heart disease. Heart-healthy lifestyle changes include:

Heart-Healthy Eating

Your doctor may recommend heart-healthy eating, which should include:

  • Fat-free or low-fat dairy products, such as fat-free 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 fat—found 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 and meats.

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:

If you eat: Try to eat no more than:

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


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 don’t have high blood pressure. Read more about DASH.


Try to limit alcohol intake. Too much alcohol can raise 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
  • 1½ 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 you’re a healthy weight in relation to your height and gives an estimate of your total body fat. To figure out your BMI, check out the National Heart, Lung, and Blood Institute’s (NHLBI) 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, you’re 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 you’re 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 event—particularly one involving anger. Also, some of the ways people cope with stress—such as drinking, smoking, or overeating—aren’t 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 coronary heart disease 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 coronary heart disease.

Everyone should try to participate in moderate-intensity aerobic exercise at least 2 hours and 30 minutes 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.

Sometimes lifestyle changes aren’t 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 arterial disease, or had a 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 stent or percutaneous coronary intervention (PCI) or surgery, such as coronary artery bypass grafting (CABG).
  • Reduce your heart’s workload and relieve coronary heart disease symptoms.

Take all medicines regularly, as your doctor prescribes. Don’t 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 coronary heart disease.

Medical Procedures and Surgery

You may need a procedure or surgery to treat coronary heart disease. Both PCI and CABG are used to treat blocked coronary arteries. You and your doctor can discuss which treatment is right for you.

Percutaneous Coronary Intervention

Percutaneous coronary intervention, commonly known as angioplasty, is a nonsurgical procedure that opens blocked or narrowed coronary arteries. A thin, flexible tube with a balloon or other device on the end is threaded through a blood vessel to the narrowed or blocked coronary artery. Once in place, the balloon is inflated to compress the plaque against the wall of the artery. This restores blood flow through the artery.

During the procedure, the doctor may put a small mesh tube called a stent in the artery. The stent helps prevent blockages in the artery in the months or years after angioplasty. Read more about this procedure at PCI.

Coronary Artery Bypass Grafting

CABG is a type of surgery in which arteries or veins from other areas in your body are used to bypass (that is, go around) your narrowed coronary arteries. CABG can improve blood flow to your heart, relieve chest pain, and possibly prevent a heart attack.

Cardiac Rehabilitation

Your doctor may prescribe cardiac rehabilitation (rehab) for angina or after CABG, angioplasty, or a heart attack. Nearly everyone who has coronary heart disease can benefit from cardiac rehab. Cardiac rehab is a medically supervised program that may help improve the health and well-being of people who have heart problems.

The cardiac rehab team may include doctors, nurses, exercise specialists, physical and occupational therapists, dietitians or nutritionists, and psychologists or other mental health specialists.

Rehab has two parts:

  • Education, counseling, and training. This part of rehab helps you understand your heart condition and find ways to reduce your risk for future heart problems. The rehab team will help you learn how to cope with the stress of adjusting to a new lifestyle and how to deal with your fears about the future.
  • Exercise training. This part helps you learn how to exercise safely, strengthen your muscles, and improve your stamina. Your exercise plan will be based on your personal abilities, needs, and interests.
