I don't know how far the heart disease I was diagnosed with had progressed prior to covid. Prior "regular" physicals and even a couple cardiologist visits didn't indicate ANY heart disease. It runs in my family so I had been a little more concerned than average. The coronary artery calcium (CAC) scan can show if you have heart disease even if there are no other symptoms. It only costs ~$100 for the scan, so I would recommend it for anyone over 40. I'm in my 60's now. I think covid caused a big ramp up in whatever calcification I had, but I'll never know because I didn't have the CAC scan until after having covid. Colas, because they have phosphoric acid, causes depletion of bone calcium, so I quit drinking that many years ago.
