@bwaykm the studies on Evenity that resulted in a black box warning showed no difference in risk between Evenity and placebo, and small (considered statistically significant) difference with alendronate. I have seen this latter result explained as because alendronate is slightly protective and also by chance.
You can look up the Arch and Frame studies and ask you doctor to explain.

I have afib with tachycardia and didn't have any heart issues with Evenity (I did have some neuro issues due to lupus).
