Cardiology is the treatment of diseases of the heart and blood vessels. A cardiologist is a physician who specializes in treating heart conditions such as abnormal heart rhythms, heart attacks, coronary artery disease, congenital heart defects, and disease of the heart valves. A cardiologist can inform your doctor about new drugs or tests that may be beneficial to you.
