I Have An Appointment With A Cardiologist On Monday. I

I have an appointment with a cardiologist on Monday. I have been experiencing shortness of breath
and sometimes have a slight tightening in my chest. My cholesterol has always been normal and have
never been on a statin. I don't get exercise and haven't been walking so I know I am out of shape. I know I have mitral valve and I think I have a leaky valve.
