You can help to prevent angina caused by coronary artery disease by controlling your risk factors for clogged arteries:
High cholesterol — Follow your doctor's guidelines for eating a diet low in fats and cholesterol and, if necessary, take medication to decrease your cholesterol.
High blood pressure — Follow your doctor's recommendations for changing your diet and taking your medication.
Smoking — If you smoke, quit. If you don't smoke, don't start.
Diabetes — Test your blood sugar frequently, follow your special diet, and take your insulin or oral medication as your doctor has prescribed.
It's also wise to exercise regularly and to maintain an ideal weight. If angina attacks are triggered by emotional stress, learning stress management or relaxation techniques may be helpful.
