Gallstone disease is associated with a 23% higher risk of developing coronary heart disease, according to an analysis published Aug. 18 in Arteriosclerosis, Thrombosis, and Vascular Biology.
“Our results suggest that patients with gallstone disease should be monitored closely based on a careful assessment of both gallstone and heart disease risk factors,” senior author Lu Qi, MD, PhD, said in a statement.
Dr. Qi, professor of epidemiology at Tulane University in New Orleans, and his coinvestigators conducted a meta-analysis of seven distinct studies, which involved a total of 842,553 patients and 51,123 cases of coronary heart disease. Patients with coronary heart disease were investigated further to determine if there was any history of gallstone disease.
Results showed that there was a 23% higher likelihood of coronary heart disease in patients who had gallstone disease, compared with those who did not, with a range of 15%-33% across the studies; the adjusted hazard ratio was 1.23 (95% confidence interval, 1.15-1.33).
Additionally, a separate prospective analysis of three of the included studies was conducted to determine individual risk factors that may contribute to the association between gallstone disease and coronary heart disease. These studies were the Nurses’ Health Study, conducted from 1980 to 2010, the Nurses’ Health Study II, which took place during 1989-2011, and the Health Professionals Follow-up Study, from 1986 through 2010, involving 112,520 women, 112,919 women, and 43,703 men, respectively.
This analysis revealed a 17% increase in coronary heart disease risk (aHR, 1.17; 95% CI, 1.09-1.26). Furthermore, the investigators noted that individuals with a history of gallstone disease who were otherwise healthy – in other words, had no history of obesity, high blood pressure, diabetes, or other disorders commonly associated with coronary heart disease – still stood a higher chance of developing coronary heart disease than individuals with no history of gallstone disease (Arterioscler Thromb Vasc Biol. 2016 Aug 18. doi: 10.1161/atvbaha.116.307507).
“Preventing gallstone disease may also benefit heart health,” Dr. Qi said.
“The potential mechanisms for the association of gallstone diseases with [coronary heart disease] may, at least, include the primary metabolic pathway and the bacterial pathway,” Dr. Qi and his coinvestigators posited, explaining that “among patients with gallstones, especially those with cholesterol gallstones, their bile acid and lecithin secretion rates tend to be depressed and cholesterol secretion rates elevated, which could indicate enhanced cholesterol synthesis and therefore increase cardiovascular disease risk.”
