Is my Cardiologist a Cardiac Surgeon as well?

Normally, we use Cardiologist and Cardiac surgeon simultaneously. But a Cardiologist is not as same as Cardiac Surgeon. A Cardiac Surgeon is more than a Cardiologist and undertakes chest and heart surgery for any serious cardiovascular issue/s. In other case, a Cardiologist is specialized in diagnosis and treatment of cardiovascular issues and does not necessarily performs surgery except heart catheterizations, inserting a pacemaker and angioplasty etc.

A study has shown that the licorice plant can help in improving overall heart health. And, if you are looking for a solution to all of your skin problems, then surely a dermatologist has all the answers.

I had my Electrocardiogram for the first time and I was too scared to do it. But my cardiologist was so experienced and polite to me. He explained all the possibilities to make me confident for the test.

It seems to be a very risky profession. I too wanted to be a cardiologist but after seeing so many risks, I dropped my plan.
