What does a cardiologist do?
A cardiologist is a physician (either an M.D. or a D.O.) who specializes in taking care
of the heart and blood vessels. Often, a cardiologist is not sought out until something
drastic happens, like the occurrence of a heart attack. It is at these times that a
cardiologist uses his expertise to open clogged arteries and saving lives. But
cardiologists are also experts in helping people control their blood pressure, reduce
their cholesterol levels, and reduce their overall risk for heart attacks and strokes.
They are concerned with helping you keep your heart healthy before any damage occurs, as
well as repairing any damage that is found.
