Angina is not a disease but usually a symptom of a lurking Coronary Heart Disease (CHD) and typically describes the excruciating and tightening pain and discomfort in the chest around the heart muscles when they do not receive enough oxygenated blood.

  • Fatigue and weakness
  • Shortness of breath and sweating
