Measurement of plasma levels of adrenomedullin in patients in the acute stages of MI showed elevated circulating levels of adrenomedullin within 24 to 48 hours of admission, which gradually decreased over a three-week period.13 On the other hand, Miyao et al.14 reported that in patients with acute MI, increased plasma levels of adrenomedullin in the very early phase of acute MI returned to normal limits approximately four weeks later. Here, ADM is linked to myocardial infarction.
