They stronly suggested a follow-up upon returning home. End result, more tests and ultimately a stent in one artery.
My recovery re: my leg is pretty much complete. Now, I'm just trying to get back into the swing of things. I'd been entertaining a bike change to a gravel bike w/dropped bars. Our bikes, my hybrid, is still up in the U.P. We are going up over Easter to bring them back. Mine will go to my grandson. I've been using a modified Schwinn (to a road bike) on a fluid trainer. Going well, today averaged about 14 mph for 30 min.
I will reiterate please be careful with your history you may have underlying issues that have not been fully revealed. Also keep in mind gravel riding is much different exercise and can be much harder on the joints then road cycling. I strongly recommend consulting your Dr about repeating the stress test. I would not put much stock in training advice from people who may be much younger than you and in much better condition.
