Relationship between elastase and total antioxidant status in young subjects with recent myocardial infarction.

In a group of young subjects with acute myocardial infarction (AMI) (68 men and 7 women; mean age 39.6+/-5.7 years) we examined the plasma concentration of elastase, the thiobarbituric acid-reactive substances (TBARS) and the total antioxidant status (TAS) at the initial stage of AMI. In this group we found an increase of elastase (p<0.001) and TBARS (p<0.001) and a decrease of TAS (p<0.001). A statistical correlation was observed in the whole group of AMI patients between plasma elastase and TAS (p<0.01) and this correlation was more statistically significant in patients with more risk factors and not in those with more involved vessels.
