I don't know much about atn but wanted to add my thoughts and prayers on the loss of your father. Stay strong.
Thank you, my concern was that my Dad's doctor should have picked it up sooner, as Dad had lower back pain for some time, but having said that he was also suffering from prostrate cancer, i guess i shouldn't expect too much from the doctor. Thank you so much for your response, and kind words.
Hi Sarah,
Im sorry you just lost your father. I hope you are doing as well as can be expected.
Im not a physician but my guess here is that the cardiac arrythmia led to your father's kidneys shutting down. If the heart has a prolonged arrhythmia, it is possible, depending on the arrythmia, for the heart to not be able to pump enough blood out to the body's other organs. If the kidneys dont receive an adequate blood supply, it can cause damamge like ATN and eventually lead to kidney failure. It can happen pretty quickly.
Wishing you well during this time, hope this helped a bit.
