Bad news today.
I've managed to keep my cholesterol at 6 (down from peak just under 10 when first picked up about 20 years ago) for the last couple of years, taking Ezetimibe but no statins (as they'd given me liver and memory loss issues) and doing 'good' lifestyle stuff (no meat / caffeine, exercising, weight, etc). But I found out this afternoon that the years of higher cholesterol before I started cycling and lost weight have taken their toll. Apparently my heart is above the 90th percentile for calcification, which is not good. So I am now on stronger drugs (Alirocumab) and off energetic exercise, at least until I see the cardiologist.
