reaction to Fasenra

I began this biologic drug, and the load (3 doses) went fine, and I was feeling much better when I had my next injection, approx. 2 hours later, I reacted with bad chest pain that radiated to my jaws, The test at emergency room went fine, but I was referred to a cardiologist that has now also wants further heart test. Of course they are taking me off this med. Has anyone else had this reaction, as I can't find it listed anywhere on possible reactions. I'd also like to continue the drug if my heart test are o.k.
