Chest Pain - should I be concerned?

I have occasional chest pain, sometimes when I run on a treadmill, never when I ride the exercise bike.  Most of the time the chest pain comes when I'm resting, kind of like a sharp pain in the middle of my chest.  I also experience palpitations throughout the course of the day.  I'm on BP medication (avapro 150mg).  My BP is usually in check running around 118/70. No family history of heart disease (except Dad passed away from cardiomyapthy, was determined to be a non-genetic virus that attacked his heart).

I'm 30 years old, 5'11 195 lbs.  I try to eat pretty healthy, lots of fruits and veggies. Exercise a few times a week.  I've had the following tests done.  Multiple EKG's, hsCRP test, holter monitor, stress test, ct heart scan (calcium score came back with a 0), chest x-ray.  

Blood work #'s:
total cholesterol: 167
triglycerides: 107
HDL: 38
LDL: 108

Do I need to be concerned about the heart palps or chest pain? I do have high anxiety (because of the chest pain and palps), and others around me seem to think I'm anxious.  I don't see it but they do.  My cardiologist isnt concerned and told me to see him in a year.  Should I seek more tests like a PET Scan? My doc doesnt think its needed and it exposes me to radiation.

Thanks!

Your chest pain may be nothing to worry about...and prehaps, simply a muscular response to your exercise on the treadmill. Should it persist, check with your cardiologist as he may consider doing a stress test (done on a treadmill) to determine if there is a problem with your heart and cardiac output when exercising.

Thanks for the feedback.  Yea, I actually did have an Echo Stress test already within the past 6 month and it came back fine.  They actually said I did really well on it and lasted 14 minutes or so.  Although I didn't have chest pain while running, so no symptoms during the test.  But, this is why I also had the 24x7 EKG monitor for 2 weeks, the CT heart scan (calcium score).  All negative.  Weird.  Maybe stress/anxiety?
