I have health news

I went to the hospital early this morning for a angiogram And had the results about 1:30 this afternoon. My stress test showed the lower left part of my heart wasn't pumping properly.The test today showed what was wrong and I was surprised by what caused the problem. We thought that I had plaque build up or some type of blockage. But that was not the case everything was clear and no blockage or plaque build up at all. Seems when I went through chemo for cancer it done damage that no one knew about. The left lower part of my heart is like a 70 year old man the veins shrank from the chemo.
