Objective
Gallstone disease has been related to cardiovascular risk factors; however, whether presence of gallstones predicts coronary heart disease (CHD) is not well established.
Approach and Results
We followed 269,142 participants who were free of cancer and cardiovascular disease at baseline from 3 U.S. cohorts: the Nurses’ Health Study (NHS; 112,520 women; 1980–2010), NHS II (112,919 women; 1989–2011) and the Health Professionals Follow-up Study (HPFS; 43,703 men; 1986–2010), and documented 21,265 incident CHD cases. After adjustment for potential confounders, the hazard ratio for the participants with a history of gallstone disease compared with those without was 1.15 (95% confidence interval [CI] 1.10–1.21) in NHS, 1.33 (1.17–1.51) in NHS II, and 1.11 (1.04–1.20) in HPFS. The associations appeared to be stronger in individuals who were not obese, not diabetic, or were normotensive, compared to their counterparts. We identified 4 published prospective studies by searching PUBMED and EMBASE up to October 2015, coupled with our 3 cohorts, involving 842,553 participants and 51,123 incident CHD cases. The results from meta-analysis revealed a history of gallstone disease was associated with a 23% (15–33%) increased CHD risk.
Conclusions
Our findings support that a history of gallstone disease is associated with increased CHD risk, independently of traditional risk factors.
