title: Altered urinary excretion of human kininase activity in acute myocardial infarction.
abstract: 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.
