[Vasopressin in acute myocardial infarct: clinical implications].
Since current data on vasopressin (AVP) secretion during the early phase of myocardial infarction is not extensive, plasma AVP was measured in 26 patients with acute myocardial infarction. Twelve had an increased AVP concentration (23.2 +/- 7.0 pg/ml; mean +/- SEM) whereas 14 had an AVP level less than 3 pg/ml (1.96 +/- 0.14 pg/ml). The patients with AVP greater than 3 pg/ml had higher heart rate and plasma osmolality than those with AVP less than 3 pg/ml. Blood pressure values were the same in both groups of patients. There was no difference in peak CPK and iso CPK activities between the two groups. Seven patients with AVP greater than 3 pg/ml died within the next few days, while only 1 patient with AVP less than pg/ml died. It thus appears that increased AVP concentration during acute myocardial infarction is associated with a poor prognosis. Whether it is a cause or a consequence of an unfavourable course of myocardial infarction remains to be determined.
