what does high levels of creatin mean to the kidneys?

my mom is in hospital awaiting a pace maker. She has been on warfarin which has been discontinued and replaced by heparin. When asked why the nurse said they were concerned about her kidneys because of high levels of creatin. Could you pls explain.
