Lifestyle changes can also help prevent some angina attacks. Your provider may tell you to:</p><ul><li>Lose weight if you are overweight</li><li>Stop smoking</li><li>Exercise regularly</li><li>Drink alcohol in moderation only</li><li>Eat a healthy diet that is high in vegetables, fruits, whole grains, fish, and lean meats</li></ul><p>Your provider will also recommend that you keep other health conditions such as high blood pressure, diabetes, and high cholesterol levels under control.</p><p>If you have one or more risk factors for heart disease, talk to your provider about taking aspirin or other medicines to help prevent a heart attack. Aspirin therapy (75 to 325 mg a day) or medicines such as clopidogrel, ticagrelor or prasugrel may help prevent heart attacks in some people. Aspirin and other blood-thinning therapies are recommended if the benefit is likely to outweigh the risk of side effects.</p></div></div></section><section><div class="section"><div class="section-header"><div class="section-title"><h2>Alternative Names</h2></div><div class="section-button"><button type="submit" aria-controls="section-Alt" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">
