Did anybody find out that their treatment had affected their heart some years down the line, and if so how? I'm currently being investigated for high blood pressure and a very fast heart rate (which started suddenly and resolved by the next day). I've had various tests and scans and am currently wearing a 24-hour heart trace monitor and a 24-hour blood pressure monitor. I had my treatment from 2007-2008. Thanks

Diagnosed June 2007, IDC, Grade 3, 4-5cm lump, several lymph nodes involved, HER2+++, 4 months of high strength chemo, mastectomy and lymph node removal, radiotherapy & a year of herceptin and recently had preventative surgery to other breast.

Herceptin effected my heart- it lowered my ejection fraction of my left ventricle such that I was almost in co festive heart failure. I had to stop treatmentbwith herceptin. Fortunately, my heart function returned to normal over time.

I am on a beta blocker and ace inhibitor to help.


I tried herceptin again and same thing hapoened.

Good news is I recovered again.

Theee is a thicjeningbif mt heart muscle from all the meds.

I think about 12% have heart issues due to Herceptin but it tends to happen during active treatment. I do know of someone (triple negative), who developed heart damage due to the chemo drugs a couple years after completing their treatment.
