BACKGROUND: There is still controversy about association of Helicobacter pylori (H. pylori) infection with coronary heart disease (CHD). This study designed to evaluate this association in a sample of Iranians Population. 

METHODS: Medical and drug history as well as fasting blood samples of 112 consecutive patients who were candidate for coronary angiography were taken on catheterization day. Fasting blood samples were used to measure C-reactive protein (CRP), anti H. pylori immunoglobulin G (anti H. pylori IgG) and interlukine-6 (IL6). According to angiography reports, participants were divided into patients with (n = 62) or without CHD (n = 43). To compare the association between H. pylori infection with CHD, multivariate logistic regression tests were used by adjusting sex and age, age and sex plus history of diabetes mellitus (DM), Dyslipidemia (DLP), and/or hypertension (HTN), CRP status and IL-6 level. 

RESULTS: Sixty two patients with CHD and 43 participants without CHD were enrolled in the present study. The mean ages of patients with and without CHD were 62.4 ± 9.5 and 59.0 ± 10.5 years respectively. Multivariate logistic regression analysis after adjusting for history of DM and/or DLP and/or HTN plus CRP status and IL-6 level showed significant association of H. pylori infection with CHD (OR 3.18, 95%CI 1.08-9.40). 

CONCLUSION: H. pylori infection is one of the probable risk factors for CHD independent of history of DM, DLP, HTN, CRP status and IL-6 level.
