It is entirely possible that your max hear rate has dropped significantly. When did you last test your max?
My guess is that if you went to max and "stayed there" then it wasn't your true max heart rate. Max heart rate is not sustainable for long periods of time.

I'm 49 y/o now.
10(ish) years ago, I observed 198HR climbing bear mountain and also in some park races (CP & PP).
This year I have observed 186 climbing Alpine and doing Hincapie intervals on the spin/trainer.
But my recent trials up Alpine haven't seen HR above ~180.
