The most common symptom of CAD is angina, which causes tightness in the chest often described as squeezing.
Symptoms of a heart attack include chest pain, which is often severe but may also feel like indigestion or heartburn, upper back or neck pain, cold sweat, dizziness or nausea, vomiting, extreme fatigue and shortness of breath.
If you have symptoms, or important risk factors, your doctor may wish to determine the extent and pattern of your coronary artery disease, to provide best advice on your care.
