hikerguy,

Things you might be able to do with support from your PCP, while waiting on the cardio appointment include:
- getting an advanced lipids panel (some call it a CardioIQ) which provides much more detail on lipids, types, etc.
- stress test with echo (echo component is important)
- ultrasound for peripheral artery disease (non-coronary locations)

Are you on statins, yet? Your PCP might want to do this, if you haven't seen them, it might make sense.
