CHD is a narrowing of the blood vessels that supply blood and oxygen to the heart.

Angina is chest pain or discomfort that most often occurs when you do certain activities or feel stressed. It is caused by poor blood flow through the blood vessels of the heart muscle.

If you have high blood pressure, diabetes, or high cholesterol, your health care provider may advise you to:

• Keep your blood pressure controlled most often to less than 130/80. Lower may be better if you have diabetes, kidney disease, stroke, or heart problems, but your provider will give you your specific targets.
• Take medicines to reduce your cholesterol.
• Keep your HbA1c and blood sugar at recommended levels.

Some controllable risk factors for heart disease are:

• Drinking alcohol. If you drink, limit yourself to no more than 1 drink a day for women, or 2 a day for men.
• Emotional health. Get checked and treated for depression, if needed.
• Exercise. Get plenty of aerobic exercise, such as walking, swimming, or bicycling, at least 40 minutes a day, at least 3 to 4 days a week aiming for at least 150 minutes per week.
• Smoking. Do not smoke or use tobacco.
• Stress. Avoid or reduce stress as much as you can.
• Weight. Maintain a healthy weight. Strive for a body mass index (BMI) from 18.5 to 24.9 and a waist smaller than 35 inches (90 centimeters).

Good nutrition is important for your heart health. Healthy eating habits will help you control some of your risk factors for CHD.

• Eat plenty of fruits, vegetables, and whole grains.
• Choose lean proteins, such as skinless chicken, fish, and beans.
• Eat non-fat or low-fat dairy products, such as skim milk and low-fat yogurt.
• Avoid foods that contain high levels of sodium (salt).
• Read food labels. Avoid foods that contain saturated fat and partially hydrogenated or hydrogenated fats. These are unhealthy fats that are often found in fried foods, processed foods, and baked goods.
• Eat fewer foods that contain cheese, cream, or eggs.

Your provider may prescribe medicine to treat CHD, high blood pressure, diabetes, or high cholesterol levels. These may include:

• ACE inhibitors
• Beta-blockers
• Calcium channel blockers
• Diuretics (water pills)
• Statins to lower cholesterol
• Nitroglycerin pills or spray to prevent or stop an angina attack

To reduce the risk of a heart attack, you may also be told to take aspirin, clopidogrel (Plavix), ticagrelor (Brilinta) or prasugrel (Effient) every day. Follow your provider's directions carefully to keep heart disease and angina from getting worse.

Always talk to your provider before you stop taking any of your medicines. Stopping these medicines suddenly or changing your dose can make your angina worse or cause a heart attack.

Create a plan with your provider for managing your angina. Your plan should include:

• What activities are OK for you to do, and which ones are not
• What medicines you should take when you have angina
• What are the signs that your angina is getting worse
• When you should call your provider or 911 or the local emergency number

Know what can make your angina worse, and try to avoid these things. For example, some people find that cold weather, exercising, eating large meals, or getting upset or stressed worsens their angina.
