Cardiology is the study and treatment of disorders of the heart and the blood vessels. A person with heart disease or cardiovascular disease may be referred to a cardiologist.
Summary
A cardiologist is a licensed doctor for the veins, arteries and heart. They diagnose and treat various cardiovascular ailments or diseases, such as heart attacks and coronary heart disease. Cardiologists may focus in one or more cardiology specializations, such as echocardiography, electrophysiology, nuclear cardiology and interventional cardiology. The tasks of cardiologists also vary. For instance, non-invasive cardiologists specialize in diagnosing cardiovascular problems, while invasive non-interventional cardiologists diagnose and perform catheterizations. Those who diagnose and perform medical procedures to cure cardiovascular diseases are called interventional cardiologists.
