Fenofibrate Use Is Associated With Lower Mortality and Fewer Cardiovascular Events in Patients With Diabetes: Results of 10,114 Patients From the Korean National Health Insurance Service Cohort

OBJECTIVE We investigated the long-term clinical efficacy of fenofibrate use with regard to mortality and cardiovascular outcomes in patients with type 2 diabetes. RESEARCH DESIGN AND METHODS We performed a population-based cohort study using data of the South Korean National Health Insurance Service from 2003 to 2014. Of 63,727 participants with diabetes aged 40-79 years, 5,057 users of fenofibrate only were compared with 5,057 nonusers of fenofibrate and/or omega-3 fatty acid with 1:1 propensity matching. The primary end point was a composite of myocardial infarction, stroke, percutaneous coronary revascularization, and cardiac death for a median of 3 years. RESULTS The primary end point was significantly lower in fenofibrate users compared with those using neither fenofibrate nor omega-3 fatty acid (13.4 vs. 15.5 per 1,000 person-years; hazard ratio [HR] 0.76; 95% CI 0.62-0.94; P = 0.010). Cardiac death (1.8 vs. 3.1 per 1,000 person-years; HR 0.59; 95% CI 0.352-0.987; P = 0.0446), all-cause death (7.6 vs. 15.3 per 1,000 person-years; HR 0.437; 95% CI 0.340-0.562; P < 0.0001), and stroke (6.5 vs. 8.6 per 1,000 person-years; HR 0.621; 95% CI 0.463-0.833; P = 0.0015) were significantly lower in the fenofibrate group. When the duration of fenofibrate use was stratified by quartile, the risk decreased in quartile 4, with an HR of 0.347 (95% CI 0.226-0.532; P < 0.0001). In subgroup analysis, the favorable effect of fenofibrate was sustained consistently across all subsets of patients, including those classified by LDL cholesterol, HDL cholesterol, and triglyceride levels. CONCLUSIONS Use of fenofibrate was associated with a lower rate of total and cardiac mortality and cardiovascular events in patients with type 2 diabetes during a 3-year follow-up in real-world large populations.
