Thanks for the update

When it gets tough just remember to be glad you live when and where you do.
I never met my paternal Grandfather. He was born in 1910 and started having heart problems in his 50's in the 1960's. I believe he'd had a couple minor heart attacks but I'm not even sure if the Doctors of that time knew for sure.
He died of a heart attack in 1970.
My dad told me once that a few weeks after his dad passed, the Cleveland Clinic called. They didn't know and were calling to schedule a visit. Basically the gist of it was that my grandfather was going to get assessed for open heart surgery but back in 1970 that was cutting edge stuff and he obviously didn't get there in time.
My dad was born in 1940 and despite my brother and I both being relatively late bloomers in the having families department, he got to see most of his grandkids basically because of modern medicine. Dad had his first heart attack at 61 in early 2002. They stuck a stent in him and sent him home and he lived almost 20 more years (including a bunch more stents).
Fifty years ago a blockage like the one you had probably would have meant chest pain and shortness of breath for a few months or maybe a few years if you were lucky and then the big one and curtains. Now, even though it couldn't be fixed with a stent, it still just means surgery and a tough recovery and your remaining lifespan is likely to be measured in decades rather than weeks.
Good luck in your continuing recovery.
