@VeeEnn I’m sure you are right.

I asked ChatGPT how safe it is to exercise strenuously with a bioprosthetic aortic valve. ChatGPT gave me a very detailed answer, including a time-staged exercise regimen after surgery. (And repetitions to always consult my cardiologist.)

Chat GPT said that there are no reports of exercise damaging a bovine bioprosthetic valve. (This is true – I did my own search.)

For a 71-year old, Chat GPT said:

  • Maximum predicted heart rate = 220 - age = ~149 bpm

  • Target heart rate zone (50–70%) for light to moderate exercise = 75–105 bpm

    • Moderate intensity (50–70% of HRmax): 74–104 bpm

  • Vigorous intensity (70–85% of HRmax): 104–127 bpm

Here’s a chart of my heart rate on a day when I did Zumba.

I admit that I was a little alarmed when my heart rate went over 160 bpm but I was having so much fun and I felt fine.

I can’t help thinking that the recommendations are for the people I see in my cardiac rehab class, not for someone who has been doing aerobic exercise for 50+ years like me. But my cardiologist would be mucho unhappy if he knew, probably.

There you go…the dangers of having too much fun. Rest assured, that’s not likely to happen on a treadmill :rofl::joy:

I can relate to that. I did xc ski races over the Winter, and per my HRM, hit max HR of 180 during a couple of the races. Using the fallible Age= 220-HR(max), I’m 21 years younger than my birth age, lol. That is a bogus equation, per everything I’ve read, so I put no stock in it. But I do think it’s good to push into your anaerobic zone, for me anyways. I do understand that it is different if one has had heart issues, but it sounds like you’ve been active all or most of your life, so you probably have some great resilience built up !
