Do you know your risk of coronary artery disease, the most common form of heart disease?

Dr. Regis Fernandes, a Mayo Clinic cardiologist, says an easy and efficient test called a coronary scan can help determine your risk before you show symptoms.

Talk with your health care team to find out if you're a candidate for a coronary calcium scan.
