Background

Although low-density lipoprotein cholesterol (LDL-C) is the primary lipid target for cardiovascular disease (CVD) risk reduction, high-density lipoprotein cholesterol (HDL-C) and triglycerides (TG) have also emerged as risk factors. This study evaluated attainment of goal/normal lipid levels in current clinical practice among high-risk patients following lipid-modifying therapy (LMT).

Methods

Data for patients aged ¡Ý 35 years and on LMT for ¡Ý 12 months were identified from electronic medical records (United Kingdom and Sweden) and extracted from medical charts (Canada and Spain). High CVD risk was defined according to the Adult Treatment Panel III guidelines. An index period was defined, from January 1995-July 2008, during which patients received an initial LMT prescription. Prevalence of lipid abnormalities was assessed 12 months before and after the index date. Multivariate logistic regressions evaluated predictors of attaining goal/normal lipid levels.

Results

Among 12,768 high-risk patients, 75 % had elevated LDL-C, 37 % low HDL-C, and 30 % elevated TG before LMT. Despite therapy (97 % statins only), 23 % had elevated LDL-C, 36 % low HDL-C, 16 % elevated TG, and 17 % had ¡Ý 2 abnormal lipid levels. Framingham risk score > 20 % (Odds Ratio, 95 % confidence interval: 0.37,0.31-0.43), diabetes (0.75,0.64-0.88), hypertension (1.26,1.09-1.46), current smoker (0.82,0.70-0.95) and increased body mass index (0.95,0.94-0.96) were associated with the likelihood of attaining ¡Ý 2 normal lipid levels (vs. LDL-C goal only).

Conclusion

Current approaches to lipid management improve LDL-C goal attainment; however, control of multiple lipid risk factors remains poor. Patients may benefit from more comprehensive approaches to lipid management, which treat multiple lipid abnormalities, as suggested in clinical guidelines.
