Cardiology is a medical specialty that treats the heart,
circulation and diseases that affect the heart. A Cardiologist may see a
patient for a simple complaint, such as high blood pressure, or for something
very complicated, such as chest pain. Routine tests that Cardiologist use to make a
diagnosis include EKG, cardiac ultrasound, stress test (walking on a treadmill)
and nuclear imaging procedures.
Cardiologist can provide continuing care of patients,
perform heart function studies, implant pacemakers, oversee treatments,
supervise drug therapy and work closely with heart surgeons. In addition, a
Cardiologist may perform annual cardiac physicals and offer wellness advice for
those persons at risk or suffering from heart disease.





If you or a loved one needs to undergo a procedure or surgery for a heart condition, it is
perfectly normal to be feeling worried and uncertain. You probably have many questions.
Although physicians try to answer all the questions they can, people often say they didn’t
understand everything their physician said or that they forgot to ask something. The
Education tab on the page is designed to answer some of your questions. The best strategy
for dealing with fear is facing it. Preparing for what you or a loved one will likely be
experiencing is the first step in approaching the situation with greater confidence and peace
of mind. Congratulations for taking this time to get all the facts.
