Tomorrow you might consider developing a relationship with a PCP and a cardiologist ... getting a full set of tests to allow professionals to assess your health.

I'm thinking something like:
- CardioIQ advanced lipids panel
- start statins (and expect your CAC to increase because statins increase calcification, but might save your life because they do)
- stress test with echo
- peripheral ultrasound
- CT Angiography (CTA)

Perhaps a comprehensive approach?
