Abstract´╝Ü Objective:To investigate the prevalence of carotid artery plaque (CP) in the population undergoing health examinations and to assess the association between CP and Helicobacter pylori (Hp) infection.Methods:The subjects were 3066 patients who underwent carotid ultrasonography examination and 13C urea breath test (UBT) at the health examination center of China-Japan friendship hospital from January 2019 to December 2019. The subjects were divided into CP and non-CP groups; the differences of physicochemical parameters and UBT positive rate between the two groups were analyzed by independent sample t test, Mann-Whitney U test, and Chi-squared test. The association between UBT positive and CP was analyzed by logistic regression. Results:The proportion of CP positive subjects was significantly higher in males than in females (33.4% vs 19.5%, P<0.001); the proportion of Hp positive subjects was not significant in sex composition (29.1% vs 30.9%, P=0.245); the age [(59.39±10.24) vs (46.44±9.88) years], P<0.01), BMI [(25.44±3.23) vs (24.21±3.54) kg/m 2, P<0.01], SBP [(135.91±19.07) vs (123.03±16.66) mmHg, P<0.01], DBP [(79.64±11.47) vs (75.10±11.55) mmHg, P<0.01], TC [(4.96±0.98) vs (4.86±0.98) mmol/L, P=0.004], TG [1.43 (1.03, 2.06) vs 1.20 (0.82,1.88) mmol/L, P<0.001], LDL-c [(3.21±0.93) vs (3.04±0.83) mmol/L, P<0.01)], FBG [5.55 (5.11,6.47) vs 5.16 (4.83,5.56) mmol/L, P<0.001], UA [(339.13±79.92) vs (319.85±87.62) mmol/L, P<0.01] and Hcy [13.10 (11.30,15.60) vs 11.7 (10.00,13.90) mmol/L, P<0.001] were significantly higher in the CP group than that in the non-CP group; HDL-c was significantly lower in the CP group than in the non-CP group [1.12 (0.95,1.32) vs 1.20 (1.00,1.43) mmol/L, P<0.001]. The proportion of male (62.4% vs 44.6%, P<0.01), prevalence of tobacco smoking (31.9% vs 19.6%, P<0.01), hypertension (33.8% vs 12.5%, P<0.01), and diabetes (13.45% vs 3.5%, P<0.01) were significantly higher in the CP group than that in the non-CP group. The proportion of UBT positive subjects was significantly higher in the CP group than in the non-CP group (34.5% vs 28.4%, P=0.001). Logistic regression analysis showed a significantly positive association between CP and UBT positive after adjusted confounding factors ( OR=1.270, P=0.028). Conclusions:The formation of CP is related to many risk factors; Hp infection is also an important risk factor. Controlling Hp infections might be one of the effective methods for the prevention and control of carotid plaque formation.
