Helicobacter pylori increases the risk of carotid plaque formation: a clinical evidence

Background and aim: Since the relation between Helicobacter pylori (H. pylori) and atherosclerosis has been evidenced, we aimed to analyze whether there is a relationship between the patient's H. pylori infection and age, gender, BMI, blood lipids, and carotid plaque formation. Methods: 810 patients from January 2016 to December 2019 were enrolled in this study, and divided the subjects into H. pylori (+) group and H. pylori (-) group based on the results of UBT. To analyze whether H. pylori infection is related to gender, age, BMI, blood lipids, and neck vascular plaque formation. Results: The single-factor analysis showed that the BMI ≥ 25kg/m(2), triglycerides >1.7 mmol/l, the formation of cervical plaques were significantly higher in patients infected with H. pylori in compared to normal cases. Also, multi-variant logistic regression analysis showed that H. pylori infection affects the BMI ≥ 25kg/m(2) and triglycerides >1.7 mmol/l to induce vascular plaque. Also, we showed that patients with H. pylori infection are 1.424 times higher than the non-infected group to have triglycerides more elevated than 1.7mmol/l. Conclusion: In this study, we conclude that H. pylori infection is an independent risk factor for higher BMI (>25), triglyceride (>1.7 mmol/l), and neck vascular plaque formation. The multi-variant analysis showed that patients with H. pylori KEY MESSAGES: H. pylori infection is an independent risk factor for higher BMI, triglyceride, and neck vascular plaque formation. H. pylori can accelerate vascular plaque formation through increasing BMI and triglyceride.
