    Abstract:
    Serum elastase-type activity, elastase inhibitory capacity and their relation to lipids were examined in 140 male patients with ischemic vascular disease (coronary, cerebral, peripheral) and in 60 control subjects. In further 24 patients with acute myocardial infarction dynamics of elastase activity, inhibitory capacity and of lipids during the course of the illness have also been investigated. Serum elastase-type activity was found to be significantly lower, inhibitory capacity significantly higher in the groups of patients than in the controls. HDL- and HDL2 cholesterol and apo-A concentrations showed significant negative correlations with elastase inhibitory capacity both in atherosclerotic and in control subjects. During the course of myocardial infarction a significant elevation of serum elastase-type activity could be observed at the end of the first week; serum triglyceride levels increased, HDL- and HDL2 concentrations decreased significantly in the first 3 weeks, then gradually approached the initial values. In the subgroup of patients with an elevation of serum elastase-like activity by more than 30% in the first week, there was a significantly higher elevation of serum GOT and LDH1 and a greater occurrence of transmural (Q) infarction than in those with a smaller variation of elastase-like activity.
