As a Urologist, I can understand your anxiety. Your fathers age isnt given. Your father has both kidney and heart problems. The creatinine is elevated, due to kidney problem. The EF ejection fraction of 15, is due to a heart problem. The leg swelling is due to multi-organ problems. Water gets accumulated, when the fluids arent filtered out by the kidneys. Chat Doctor.
