In a large cohort of patients with cirrhosis, hypercholesterolemia was associated with well-preserved hepatic function and reduced mortality. However, each cumulative year of statin exposure was associated with an independent 8.0% to 8.7% reduction of mortality of patients with cirrhosis of Child-Turcotte-Pugh classes A and B. Researchers performed a retrospective cohort study of patients with newly diagnosed cirrhosis in the Veterans Health administration. Participants were divided into 2 cohorts: 21,921 patients with prior statin exposure (existing users) and 51,023 statin-naïve individuals, of whom 8,794 subsequently initiated statin therapy (new initiators) and 44,269 did not (non-initiators). Among the findings:
- In statin-naïve subjects, every 10 mg/dL increase in baseline total cholesterol was associated with a 3.6% reduction in mortality.
- Among existing users, each year of continued statin exposure was associated with a hazard ratio (HR) of 0.920 for mortality.
- Each year of statin exposure among new initiators was associated with a HR of 0.913 for mortality, after risk-set matching.
