I had difficulties on herceptin and it was stopped and I thought possibly the AC may have contibuted to it. It did recover but took some time. I know they have done some studies now changing the regime to see if survival rates are different dropping one chemo out of the AC part of the regime. I've had to work really hard to get my fitness back but I don't believe I will be like I was. My oncologist considered retesting my heart again due to my ongoing fatigue but we haven't as once ny sleep was sorted it seemed to pretty much resolve.
I think this is a timely reminder to have regular GP reviews. If breathless, tired constantly, have a cough or swollen feet duribg ir well after chemo...get checked out but prompt the GP about your history of chemotherapy. Medications can certainly improve cardiac function/ output and potentially decrease the progress of heart disease.
