@toniparks can't be certain what lead to the heart issues. It can take years for treatment related heart issues to develop. In the past I had radiation on my left lung and a few years later for a left side breast cancer.

Neither my cardiologist or my oncologist could say with any degree of certainty that it was the carbo, Alimta, or keytruda. It could be none of the above or all of the above. I'm planning to consult with a cardio-oncologist when or if I need treatment again.
