Abstract

Aim

Coronary artery disease (CAD) is the major cause of death nearly all over the world, and accurate and rapid diagnosis of CAD is of major medical and economic importance. The aim of this study was to evaluate the serum and saliva levels of cathepsin L in patients with acute coronary syndrome (ACS).

Materials and methods

In a cross-sectional study, 39 patients with ACS and 28 with controls were recruited to the study, and cathepsin L levels were measured in serum, resting saliva, and stimulated saliva obtained 12 and 24 h after the onset of ACS by ELISA method. Statistical analyses of Fisher's exact test, the Student's t-test or Kruskal-Wallis test were performed.

Results

Stimulated saliva cathepsin L levels in patients with ACS 12 hours but not 24 hours after admission showed significant decrease compared with that in control subjects. However, there were no significant differences in serum and unstimulted saliva cathepsin L levels between groups.

Conclusion

Serum and saliva levels of cathepsin L remain unchanged in patients with ACS and hence may not be a promising factor in CAD risk assessment.

Clinical significance

It seems that serum and saliva cathepsin L may not be a good biomarker for CHD.

Abbreviations

CAD: Coronary artery disease, ACS: Acute coronary syndrome, CHD: Coronary heart disease, EU: Emergency unit, MI: Myocardial infarction.
