I have to say "me, too". I am a fit 71 yo male who had no real family history of heart disase although my dad was diagnosed with CAD as a side finding during scans for esophageal cancer. He passed from the cancer aged 85, never having had a heart attack.

I had always had moderately high cholesterol that mimicked my dad's, and rising as I got older. But I was also a hard core runner, swimmer, cyclist, etc, who had done maybe 150,000 miles on my bikes over the last few decades and ate a reasonable diet so I was arrogant enough to believe I was fine. When my LDL cholesterol got up to ~170 in my 60s the doc wanted a calcium score, which came back ~1000! Damn.

Since I am asymptomatic and "passed" a nuclear stress test, which I was told meant I didn't have anything blocked more than 70%, I have not yet had an angiogram. I am on daily baby aspirin, Zetia, and now 20mg Crestor. I had been on 40mg but my liver ALT was a bit out of range. Still out of range on 20mg but not as bad. I continue to ride and stay as active as I can possibly be. My LDL is 73, which is just above the 70 that the doc wants. But it still feels like I am living on borrowed time.

There is somewhat of a lesson here, that many, including me are too arrogant to recieve when young. What you do and eat in your youth makes a big difference. I grew up in the age of trans-fats which were literally in everything back in the day and I will fully admit my diet wasn't great then. I grew up in the south and especially loved fried chicken and seafood and had my share of fast food. When we are young we all belive that we can eat anything and everything as long as our weight is good. Unfortunately nothing could be further from the truth. Bad diets when you are young are a ticking time bomb.
