Abstract
INTRODUCTION: Chronic inflammation caused by Helicobacter pylori (H.pylori) infection has a pathogenic role in Cardiac Syndrome X (CSX). In addition, it has shown that bacterial infection may affect blood lipids. AIM: To assess if H.pylori affects the level of lipid profile in CSX. MATERIALS AND METHODS: Eighty-eight CSX patients and 97 healthy controls were enrolled. The Total Cholesterol (TC), Triglyceride (TG), Lipoprotein A (LP{A}), Low Density Lipoprotein (LDL), High Density Lipoprotein (HDL), Apoprotein A1 (APOA1), and Apoprotein B (APOB) was estimated colorimetrically. In addition, the presence of IgG antibody to H.pylori was tested in plasma samples by using enzyme linked immunosorbent assay method. RESULTS: TC, LP{A}, LDL, APOA1 and APOB levels in CSX group were significantly higher than those of the control group (p<0.05). But, these parameters in H.pylori positive and H.pylori negative, among CSX and control groups were not significant. CONCLUSION: Increased plasma level of lipid profile and H.pylori infection were associated with CSX; it seems that plasma lipid disorders have a significant role in the development of CSX.
