Yeah, that may not be analogous though. In my example, I was riding an airdyne doing cardio. That gets the chambers pumping to full expansion to move volume of oxygen to the muscles.
In weight training the contraction and pushing the blood really hard is the main function. Thats likely where the concern at this point lies.
It gets pretty case by case specific. Like, I had damage done to the area of the heart that is fed by the circumflex and lower branches of the right coronary artery due to blockage. So once the tissue scarred and healed, I had to try to get as much flow and volume back as I could, typically measured as LVEF (left ventricular ejection fraction) with some significant cardiac hypertrophy. So, because of the blockage, the muscle was contracting really hard to push blood through the narrowing artery. Like any muscle, it got bigger and stronger. Not in a good way. That hard pushing instead of smooth high volume pumping reduces the ejection fraction, which is measuring the difference of the left ventricle at full expansion vs. full contraction, expressed as a percentage.
Ideally one would want it to be like 75-80%. Thats like 100% fully opened, then it contracts, pushing the blood, by about 75-80%. Gives you a nice high volume pump of blood. With some damage and/or cardiac hypertrophy, depending on the extent and location- you might get like 40-60%, or even less than 40 but thats a big danger zone.
So thats the differences and problems that can arise from high blood pressure, and the heart beating harder to overcome stuff like hypertension or a wonky valve or other stuff that makes it harder to push.
And, thats just a laymans overview. I had to educate myself of the specifics of my own condition after the fact, in consultation with my cardiologist.
But there could be some early interventions that can really keep your life on track, albeit with a bit of temporary sidetracking, or if left unattended can change your life for the worse, permanently.
Wish you the best, truly.
