Altered urinary excretion of human kininase activity in acute myocardial infarction.
This study concerns the determination of levels of human urinary kininase excretion in acute myocardial infarction (AMI). The results obtained by a biological method show that there is a significant reduction of the enzymatic activity in patients affected by AMI in comparison with normals (6.4 +/- 0.4 ng of destroyed bradykinin/min. versus 164.4 +/- 31.4 ng; P less than 0.001), while urinary kallikrein excretion was close to normal values.
