title: Plasminogen activator activity in venous walls of patients who died of myocardial infarction.
abstract: The aim of this study was to compare the activity of the plasminogen activator in walls of various veins obtained from 29 patients who died of myocardial infarction in the first 24 h. The control group consisted of 12 dissected persons without thrombotic complications before death. The activity of the plasminogen activator was determined by using the chromogenic substrate S-2251 according to SHIMADA technique. The twofold higher plasminogen activator activity was found in vessels of patients who died of myocardial infarction in comparison with persons who died of other causes. A significant correlation between the plasminogen activator activities of veins obtained from different parts of the body was also stated.
