Key points about unstable angina
  • If you have an attack of unstable angina, you need to go to the hospital right away for treatment. This is to lower your risk of having a heart attack.
  • Unstable angina can feel like an ache, a pain, a burning feeling or heavy pressure in your chest that usually lasts for about 20 minutes.
  • You can also feel pain and discomfort in your back, arm, jaw or throat.
  • Unstable angina usually happens when the arteries in the heart get narrow from a buildup of fat. Doctors call this coronary artery disease.
  • Even if the pains go away, you should tell your doctor about any chest pains you’ve experienced.
  • People with unstable angina must take medicines, some for life, to lower the risk of having more attacks of unstable angina.
Once your condition is stable, your doctor will talk with you about things you can do to improve your health and stop your angina and heart disease from getting worse. To prevent another attack your doctor will suggest that you stop smoking, eat healthy, lose weight, limit the stress in your life, exercise, and reduce how much alcohol you consume. You will also need to take medication and possibly go through a medical procedure to unblock your arteries.
