My wife has had open heart surgery for replacement of a mitral valve and repair a hole in her heart. She still has a 25% Injection Fraction. She has no kidneys, in dialysis, and is in cardiac rehab. She has no spleen and half a pancreas. She can only have 32 ounces of fluid per day, so she eats ice to control her fluid intake. She has swollen legs that look broken out and is now showing some blood in her stool. Can the ice contribute to the bleeding? From what I can tell, symtoms may be congestive heart failure ,but not sure. She has dialysis tomorrow, but I am concerned. BP looks normal, no fever, no coughing, no respiratory, or any other symtoms she had from before when diagnosed with congestive heart failure.
