Hi,
Your cholesterol levels are very good and with most of the tests coming back as normal, I don’t see you standing a chance of suffering from CAD in near future. However, a stress ECG (TMT) can further assure of your coronaries being clear of any significant plaque buildup. I sincerely hope that helps. Take care.
