I had an ASCT in 2017 and did well after - maintenance with Revlimid until March 2020. Anticipating COVID hitting the US my oncologist and I decided to take a break since my M-spike was low and stable. Started treatment again in January of this year since M-spike was starting to rise. Currently doing DaraFastPro and Revlimid (10 mg 14/7) with 20mg Dex on Dara injection days. My biggest concern is the effects of long term Revlimid on my heart. I had AFIB when I was in the hospital for my ASCT and subsequently had 2-3 episodes a year. These episodes were basically "self inflicted" if I got dehydrated and tired. Since starting treatment again in January AFIB episodes have become more frequent. Would like to hear if anyone has had similar experiences and if the episodes became less frequent once Revlimid was stopped. My cardiologist is not concerned at this point and my oncologist doesn't think it's related to treatment but info on long term Revlimid use indicates arrhythmias can occur.
