Question about stopping Erleada

I was on Erleada for 3 years and then my doctor stopped it because he was concerned it may be affecting my heart. My PSA was nondetectable at the time and still is after four months with only hormone treatments. My doctor says to stay off it with monthly PSA tests. Has anyone gone off Erleada and had their PSA rise? If so, did restarting the Erleadaa bring it down again?
