Cardiologists are doctors who specialise 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.
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 specialise 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.
What Does a Cardiologist Do?
Cardiologists are qualified to treat heart attacks, heart failure, heart valve disease, arrhythmia, and high blood pressure. Cardiologists work in hospitals as well as private practices.
To make a diagnosis, cardiologists may give physical exams, order tests — such an electrocardiogram (EKG), blood tests, exercise stress tests — as well as interpret tests. They may also prescribe medicine, recommend lifestyle changes such as diet, exercise, reducing stress levels and managing weight. Cardiologists can perform procedures such as implanting a pacemaker or inserting a cardiac catheter.
Cardiologists may teach at universities and do research within labs to develop new treatments.
