Unstable angina

  • Alternative Names

    Accelerating angina; New-onset angina; Angina - unstable; Progressive angina


    Prevention

    Lifestyle changes can help prevent some angina attacks. Your doctor may tell you to:

    • Lose weight if you are overweight
    • Stop smoking
    • Exercise regularly
    • Drink alcohol in moderation only
    • Eat a healthy diet that is high in vegetables, fruits, whole grains, fish, and lean meats

    Also keep strict control of your blood pressure, diabetes, and cholesterol levels. Some studies have shown that making a few lifestyle changes can prevent blockages from getting worse and may actually improve them.

    If you have one or more risk factors for heart disease, talk to your doctor about taking aspirin or other medicines to help prevent a heart attack. Aspirin therapy (75 - 325 mg a day) or a drug called clopidogrel may help prevent heart attacks in some people. Aspirin therapy is recommended if the benefit is likely to outweigh the risk of side effects.
