Background: Gallbladder diseases after acute cerebral infarction are relatively rare, but could have a serious impact on mortality and morbidity of patients. The purpose of this study was to investigate the risk of gallbladder disease in patients with acute cerebral infarction.
Methods: This study analyzed a population-based matched cohort constructed using National Health Insurance Service-Senior cohort dataset in South Korea. Subjects after acute cerebral infarction during 2002-2015 were identified as the exposed group, and up to four individual matched for age, sex, and index years were as the controls. The difference of the risk of gallbladder disease between the exposed and control group was evaluated using Cox regression adjusting for hypertension, diabetes, liver diseases, and the modified Charlson Comorbidity Index (mCCI). The risk of gallbladder disease of the exposed group was evaluated using Cox regression analyses to identify the risk factors.
Results: The occurrence of the gallbladder disease was significantly associated with the acute cerebral infarction (p<0.0001).
The presence of acute cerebral infarction was associated with a higher risk of gallbladder disease (adjusted hazard ratio=1.44, 95% confidence interval=1.26-1.66). The subjects with higher CCI showed higher risk of gallbladder disease. Among acute cerebral infarction patients, the oldest group, subjects having liver diseases, or subjects with the mCCI higher than two were found significant on the risk of gallbladder disease.
Conclusions: Our study showed that the acute cerebral infarction has a significant association with gallbladder disease. These results suggested that the possibility of developing of gallbladder disease in patients with acute cerebral infarction should be considered.
