CGA and myocardial infarction: To find out whether plasma CgA could serve as a prognostic marker for myocardial infarction, Omland's group measured plasma CgA in 119 patients (88 men; 31 women) on day 3 after the onset of myocardial infarction.53 They found significantly higher plasma CgA levels in patients with symptoms and signs of HF (0.61 versus 0.49 nM); the mortality rate was significantly higher in patients with plasma CgA of >0.49 nM.
