One of the documented side effects of statins is an increase in blood glucose level. To decrement glycogen while the precursor blood glucose level is higher? Not likely; perhaps you should request a move to pills and ills.
Disclaimer: I started taking a statin after my heart attack, so my comparison is across a major medical emergency and a few months' recovery. That said, I'd rather have had something, perhaps psychological, to gripe about that wasn't life-threatening, than the fall through the trap door into the cardiac patient ward!
