Symptoms and Complications
The key symptom of CAD is heaviness or pressure in the chest, but it may also be felt in the arms, jaw, throat, or upper back. Symptoms usually occur when you exert yourself and will go away with rest. However, not everyone with coronary artery disease experiences warning signs. In fact, some people will only notice significant fatigue or tiredness with exercise. The main complications of CAD are angina and heart attack.
