@asolidrock Your cardiologist did the Echo and stress test because of your chest pain. Echo shows pumping strength, structural issues , valve problems and nuclear stress shows blood flow through your heart muscle. He was looking for the cause of your pain. I'm glad to hear that it has diminished, for the most part. Does he think that the chemo had any effect on your heart? I hope you are doing well with with your treatment. Best wishes and prayers on your continued journey!!!
