Abstract
Introduction
We investigated the probable role of free-radical damage in the pathogenesis of slow coronary flow (SCF) by using oxidative stress parameters.
Methods
Sixty-four patients with angiographically proven SCF and 63 patients with normal coronary flow (NCF) pattern with similar risk profiles were enrolled in this study. We measured erythrocyte superoxide dismutase (SOD), reduced glutathione (GSH), serum malondialdehyde (MDA), catalase and myeloperoxidase (MPO) levels in all subjects.
Results
There were statistically significant differences in the levels of erythrocyte SOD, GSH and serum MDA between the 2 groups. Serum MDA (P=0.003) and erythrocyte SOD levels (P=0.0001) were increased in the SCF group. The level of erythrocyte GSH (P=0.010) was lower in patients with SCF. There were no differences between the groups’ serum catalase (P=0.682) and MPO levels (P=0.070).
Conclusion
Our data showed that in patients with SCF, serum MDA and erythrocyte SOD levels were increased while erythrocyte GSH levels were decreased significantly, compared with NCF patients. These results indicate that free-radical damage may play a role in the pathogenesis of SCF.
