What is cardiology?

Cardiologists are doctors who specialize in diagnosing and treating diseases or conditions of the heart and blood vessels—the cardiovascular system. You might also visit a cardiologist so you can learn about your risk factors for heart disease and find out what measures you can take for better heart health. Texas Heart Institute cardiologists are listed in the professional staff directory.

When you are dealing with a complex health condition like heart disease, it is important that you find the right match between you and your specialist. A diagnosis of heart or vascular disease often begins with your primary care doctor, who then refers you to a cardiologist. The cardiologist evaluates your symptoms and your medical history and may recommend tests for a more definite diagnosis. Then, your cardiologist decides if your condition can be managed under his or her care using medicines or other available treatments. If your cardiologist decides that you need surgery, he or she refers you to a cardiovascular surgeon, who specializes in operations on the heart, lungs, and blood vessels. You remain under the care of your cardiologist even when you are referred to other specialists.
