Clinical guidelines have recommended a LDL-C goal of <100 mg/dL for high-risk individuals and lipid-modifying therapy for patients not reaching this goal.


This investigation assessed low-density lipoprotein cholesterol (LDL-C) levels and treatment patterns among patients diagnosed with atherosclerosis with or without a previous cardiovascular disease (CVD) event.


We conducted a retrospective study by using claims data from a national health plan that included patients with ≥ 1 medical claim for atherosclerosis (ICD-9 of 440.xx, 414.x, 437.0, 437.1, or 437.3) between January 2004 and March 2006. Use of lipid-modifying medications at the time of diagnosis and thereafter, patient demographics, comorbid conditions, baseline, and postdiagnosis LDL-C were assessed.


There were 311,567 patients who had an atherosclerosis ICD-9 code, 46% of whom had a previous CVD event. Among patients with an atherosclerosis diagnosis and CVD event, lipid-modifying therapy was received by 50% before diagnosis and 57% after diagnosis, compared with 37% before and 48% after diagnosis for patients with an atherosclerosis diagnosis and no previous CVD event. Of the patients with baseline LDL-C (15%, n=46,923), 44% had an LDL-C <100 mg/dL at diagnosis; of those with LDL-C ≥ 100 mg/dL, only 54% received lipid-modifying therapy and only 64% achieved an LDL-C <100 mg/dL in the 12 succeeding months. Among patients with baseline and postdiagnosis LDL-C values (n=24,724), 55% had a baseline LDL-C ≥ 100 mg/dL and 46% had a baseline non-HDL-C ≥ 130 mg/dL.


In conclusion, many patients in a managed care plan diagnosed with atherosclerosis with or without a previous CVD event present opportunities for better lipid management. Healthcare providers should evaluate more aggressive lipid management interventions for these patients for potential downstream cardiovascular benefits.

To evaluate the safety profile of extended-release niacin/laropiprant (ERN/LRPT), pooling data from studies in the clinical development program.


Data were pooled from three active- or placebo-controlled phase 3 studies and three 1-year extensions of phase 2 studies that ranged from 12 to 52 weeks (N = 4747): ERN/LRPT = 2548; ERN or Niaspan® (ERN-NSP = 1268); or simvastatin or placebo (SIMVA-PBO = 931).


The safety and tolerability profile for ERN/LRPT was similar to that of ERN-NSP, except for fewer flushing-related adverse experiences and discontinuations with ERN/LRPT than ERN-NSP. The incidence of consecutive ≥3x the upper limit of normal increases in alanine aminotransferase and/or aspartate aminotransferase was numerically (but not statistically) greater with ERN/LRPT (1.0%) than ERN-NSP (0.5%) and similar to SIMVA-PBO (0.9%). Elevations were reversible with therapy discontinuation and not associated with clinical hepatotoxicity. There was no evidence that ERN/LRPT administered alone or concurrently with a statin had adverse effects on muscle. ERN/LRPT and ERN-NSP produced small median increases in fasting blood glucose levels (∼4 mg/dL) after 24 weeks of treatment, consistent with known effects of niacin.


The favorable safety and tolerability profile of ERN/LRPT for up to 1 year supports the use of LRPT to achieve improved therapeutic dosing of niacin, an agent with comprehensive lipid-modifying efficacy and shown to reduce cardiovascular risk.
