Hi Jaymaysea,
I'm always in favour of trying something less invasive first. Everything has risks and you have to make peace with that, and decide for yourself what's right for you. As it was explained to me by my specialist, Camzyos has about a 5% chance of relaxing the heart too much which can result in heart failure due to insufficient pumping if continued . This is why we go for monthly echo cardiograms to ensure all is well. I was also told that of those 5% who had issues, no mortality occured and stopping the drug completely reversed the negative effect.
I had a short gap in presecription due to a communication mix up at the end of April and the beneficial effects of Camzyos started to wear off by the 5th day, I would presume this time would be similar if you stopped taking it due to a negative effect.
