Clinical Information

  • A disorder characterized by substernal discomfort due to insufficient myocardial oxygenation.
  • A heart condition marked by paroxysms of chest pain due to reduced oxygen to the heart.
  • Angina is chest pain or discomfort you get when your heart muscle does not get enough blood. It may feel like pressure or a squeezing pain in your chest. It may feel like indigestion. You may also feel pain in your shoulders, arms, neck, jaw or back. Angina is a symptom of coronary artery disease (cad), the most common heart disease. Cad happens when a sticky substance called plaque builds up in the arteries that supply blood to the heart, reducing blood flow.there are three types of angina: stable, unstable and variant. Unstable angina is the most dangerous. It does not follow a pattern and can happen without physical exertion. It does not go away with rest or medicine. It is a sign that you could have a heart attack soon.not all chest pain or discomfort is angina. If you have chest pain, you should see your health care provider.
