I am 85. I had a triple bypass 2 years ago. I was given a heart doctor afterwards, not the one who performed the surgery. Recently he had me take a battery of tests. He said that one indicated that my heart was pumping lower than he said it should.
He wants me to consider installing a stent. But first he would insert something from my groin to my heart to see whether a stent might help. Then if it seemed good to install the stent, he would suggest doing that in a separate operation.
I have no complaints that would suggest a heart problem. No chest pains, for example. The only complaint is lower back pain when walking, and some thigh pains which make fast walking difficult.
Generally I am against operations unless essential, so have delayed doing anything for at least a year. Does this seem foolish? My father and grandfather both died a few years before reaching my age, but my great grandfather lived to be 89. Maybe that was because he didn't see doctors? <grin>
