The prognostic role of copeptin has been reported in various types of acute illness, including hemorrhagic/septic shock, lower respiratory tract infection, heart failure, and acute myocardial infarction5, 6, 8, 21, 22, 23; a higher copeptin level has been associated with all of these conditions and also predicts outcomes following heart failure and acute myocardial infarction. This evidence concerns the gene AVP and acute myocardial infarction.
