Kisqali and Letrozole have heart issues?

Oh, and I just remembered that I started Letrozole 2 weeks after I started Kisqali because I wanted to be able to tell which med was causing which side effect so the heart issues started with the Kisqali before I started letrozole. Arrhythmias and QT prolongation are both listed as possible side effects to Kisqali even though my oncologist tells me the afib is just a coincidence. Sure. Coincidence is his favorite word.

Thanks for the info! I started the Letrozole in November (2023) and as far as I could tell was having no issues. Started the Kisqali the beginning of February 2024 (2 months later) This heart attack/issue happened on August 12th so about 6 months later. I am leaning toward the Kisqali too. I have an appointment soon with Oncology/Cardiac and hoping to get straightened out - the medications were working so well for the cancer. . .Hope you are doing well!
