BackgroundThe American Heart Association recognizes high triglycerides as a cardiovascular risk factor.Methods and ResultsThis retrospective observational administrative claims analysis (Optum Research Database) included statin‐treated patients ≥45 years old with diabetes mellitus and/or atherosclerotic cardiovascular disease, triglycerides 2.26 to 5.64 mmol/L, and a propensity‐matched comparator cohort with triglycerides <1.69 mmol/L and high‐density lipoprotein cholesterol >1.04 mmol/L. In the high‐triglycerides cohort versus comparators (both n=10 990, 49% women), mean age was 61.7 versus 62.2 years and follow‐up was 41.3 versus 42.1 months, respectively. Multivariate analysis of composite major cardiovascular events demonstrated significantly increased risk in the high‐triglycerides (n=13 411 patients) versus comparator (n=32 506 patients) cohorts (hazard ratio [HR], 1.35; 95% confidence interval [CI], 1.225–1.485; P<0.001), with significantly higher risk for nonfatal myocardial infarction (HR, 1.35; 95% CI, 1.19–1.52; P<0.001), nonfatal stroke (HR, 1.27; 95% CI, 1.14–1.42; P<0.001), and need for coronary revascularization (HR, 1.51; 95% CI, 1.34–1.69; P<0.001), but not unstable angina or cardiovascular death. Increased cardiovascular risk in the high‐triglycerides versus comparator cohort was maintained, even with addition of non–high‐density lipoprotein cholesterol to the multivariate model and when analyzing high and low high‐density lipoprotein cholesterol subgroups. Average total healthcare cost per patient per month (cost ratio, 1.15; 95% CI, 1.084–1.210; P<0.001) and rate of occurrence of inpatient hospital stay (HR, 1.17; 95% CI, 1.113–1.223; P<0.001) were also significantly greater in the high‐triglycerides cohort.ConclusionsIn this real‐world analysis, patients with high cardiovascular risk and high triglycerides had worse composite cardiovascular and health economic outcomes than patients with well‐managed triglycerides and high‐density lipoprotein cholesterol >1.04 mmol/L.

Objective: To retrospectively investigate the real-world impact of elevated triglyceride (TG) levels on cardiovascular (CV) outcomes, medical resource utilization, and medical costs using observational administrative claims data from the Optum Research Database. Methods: Patients with one or more claims for statin therapy between January 1, 2010, and December 31, 2010, and 6 months or more of baseline data prior to the index date were eligible for inclusion in the study. Patients aged 45 years or older with diabetes and/or atherosclerotic CV disease were included and analyzed in an elevated TG cohort (!150 mg/dL) vs a comparator cohort with TG levels less than 150 mg/dL and high-density lipoprotein cholesterol (HDL-C) levels greater than 40 mg/dL. Results: In the elevated TG vs propensity-matched comparator cohorts (both N¼23,181 patients), the mean age was 62.2 vs 62.6 years, mean follow-up was 41.4 vs 42.5 months, 49.7% (11,518) vs 49.5% (11,467) were female, 83.7% (19,392) vs 84.0% (19,478) had diabetes, and 29.8% (6915) vs 29.3% (6800) had atherosclerotic CV disease. In the elevated TG (N¼27,471 patients) vs comparator (N¼32,506 patients) cohorts, multivariate analysis revealed significantly greater risk of composite major CV events (hazard ratio [HR], 1.26; 95% CI, 1.19-1.34; P<.001), nonfatal myocardial infarction (HR, 1.32; 95% CI, 1.20-1.45; P<.001), nonfatal stroke (HR, 1.14; 95% CI, 1.04-1.24; P¼.004), and need for coronary revascularization (HR, 1.46; 95% CI, 1.33-1.61; P<.001) but not unstable angina (P¼.53) or CV death (P¼.23). Increased CV risk was maintained with the addition of noneHDL-C to the multivariate model and with high and low HDL-C subgroup analysis. Total direct health care costs (cost ratio, 1.12; 95% CI, 1.08-1.16; P<.001) and inpatient hospital stays (HR, 1.13; 95% CI, 1.10-1.17; P<.001) were significantly higher in the elevated TG cohort vs the comparator cohort. Conclusion: Statin-treated patients with TG levels of 150 mg/dL or greater had worse CV and health economic outcomes than those with well-managed TG (<150 mg/dL) and HDL-C (>40 mg/dL) levels.
