Association between gallstone disease and carotid intima-media thickness: a prospective observational cross-sectional study in a tertiary care center

Abstract

Background and objectives: Gallstone disease (GD) is a prevalent health issue globally, particularly in developed nations, and has notable associations with cardiovascular disease (CVD). This prospective observational cross-sectional study aimed to investigate the association between gallstone disease and carotid intima-media thickness (CIMT), a marker of carotid atherosclerosis, in a tertiary care setting. Method: Conducted at a tertiary care center, the study included 96 participants (48 with gallstone disease and 48 age and sex-matched controls). Data collection involved demographic information, BMI calculation, abdominal ultrasonography for gallstone detection, and carotid ultrasonography for CIMT measurement. Statistical analysis was performed using SPSS version 26. Results: The study revealed higher CIMT values in GD patients compared to controls (P<0.001). Additionally, a positive correlation was observed between CIMT and age (r=0.450, P<0.001) and BMI (r=0.550, P<0.001). The Cohen’s d-test indicated a clinically significant difference in CIMT between GD patients and controls (d=1.47). Conclusion: This study revealed a significant association between gallstone disease and elevated CIMT, correlating with higher BMI indicating a potential link between gallstone disease and increased risk of carotid atherosclerosis. These findings highlight the importance of assessing cardiovascular risk in patients with gallstone disease, highlighting the potential utility of carotid ultrasonography as a non-invasive screening tool. Early intervention strategies may be warranted to mitigate cardiovascular risks associated with gallstone disease.
