Just another vote for a 2nd opinion at a CCC. I have cardio vascular disease and treatment can be difficult on the heart. A team approach (including your cardiologist) from a comprehensive cancer center is the best bet.
I'll share a silver lining with you. The treatment is brutal but doable. In the process I lost 35lbs (60 total from last August). Due to the weight loss and subsequent diet (about 80% tube feedings), my blood work and blood pressure are now perfect! My cardiologist took me off of my BP med and lowered my dose of beta blocker to the minimum.
