Lipoprotein (a): Perspectives from a lipid-referral program

Academic Article

Abstract

  • Background: Lipoprotein (a) [Lp(a)] has a strong association with coronary disease (CHD). We evaluated the implications of implementing a niacin strategy in persons above low risk by the Framingham risk score (FRS). Methods: Patients referred to a university lipid management program from January 2004 to June 2010 had an Lp(a) level measured at initial evaluation. Factors associated with an increase in Lp(a) and predictors of a high risk Lp(a) (≥50 mg/dL) were assessed. FRS and Lp(a) levels were used to assess eligibility for niacin with an Lp(a) ≥50 mg/dL. Results: A total of 692 patients (57% male, mean age 52 ± 14 years) had a mean Lp(a) of 32 ± 40 mg/dL. In a multiple logistic regression model, African-American race, female gender, presence of CHD, and lower triglyceride levels were significant predictors of high risk Lp(a). Ten percent were determined to be intermediate and 44% high risk by FRS. A total of 9% of intermediate- and 26% of high-risk patients had an Lp(a) ≥50 mg/dL, and 84% were not taking niacin. A total of 19% of moderate- and high-risk patients were eligible for initiation of niacin based upon values ≥50 mg/dL. If niacin were also used for an high-density lipoprotein cholesterol levels ≤40 mg/dL, only 5.1% additional patients would require niacin. Conclusion: High-risk levels of Lp(a) are associated with female gender, African- American race, and CHD. 19% of moderate and high risk patients would be candidates for treatment with niacin if the indication is a cutpoint Lp(a) ≥50mg/dL. © 2012 National Lipid Association.
