Is It due to Difference in LDL reduction or Different in anti inflammatory effect ?

Muhlestein, a,b,*, Jeffrey L. Anderson, a,b, Benjamin D. Horne, a, John F. Carlquist, a,b, Tami L. Bair, a, T.Jared Bunch, a, Robert R. Pearson,
Treating to dual targets Investigators also further stratified patients based on levels of CRP and LDL cholesterol: LDL cholesterol >70 mg/dL and CRP >2.0 mg/L. LDL cholesterol >70 mg/dL and CRP <2.0 mg/L. II LDL cholesterol <70 mg/dL and CRP >2.0 mg/L. LDL cholesterol <70 mg/dL and CRP <2.0 mg/L. "Even with the most aggressive statin that we have used to date, 56% of patients still did not make it to the dual target,"
What can we do to patient with LDL reaching the goal But wit persistently high CRP?

Waiting for the big trials Treating to New Targets (TNT) trial(Atorva80 Vs Atorva 10) + 10000 CHD patients and should be completed in December 2004. In this trial, patients are treated to different goals to compare the conventional NCEP guideline of an LDL cholesterol goal of less than 100 mg/dL with a more aggressive LDL cholesterol goal of less than 75 mg/dL. The Study of the Effectiveness of Additional Reduction in Cholesterol and Homocysteine with Simvastatin and Folic Acid/Vitamin B12(SEARCH) (Simva 20 Vs Simva 80) Compares the intensity of lipid lowering, rather than specific goals, in 12000 subjects who have had a prior MI. The Incremental Decrease in Endpoints through Aggressive Lipid Lowering(IDEAL) trial (Atorva 80 Vs Simva 20 or Simva 40) 7600-patient, investigating whether additional clinical benefits can be achieved by greater percentage reductions in LDL-cholesterol levels in patients with existing CHD.

Absence of interaction between atorvastatin or other statins and clopidogrel: results from the interaction study. All patients (n = 75) received 325 mg of aspirin daily for at least 1 week and 300 mg of clopidogrel immediately prior to stent implantation atorvastatin (n = 25), any other statin (n = 25), or no statin (n = 25) for at least 30 days prior to stenting conventional aggregometry, rapid analyzers, and flow cytometry comparison of platelet biomarkers 4 and 24 • Statins in general, and atorvastatin in particular, do not affect the ability of clopidogrel to inhibit platelet function. • statins may inhibit platelets directly via yet unknown mechanism(s) possibly related to the regulation of the PAR-1 thrombin receptors Arch Intern Med. 2004 Oct 11;164(18):2051-7 Serebruany VL, Midei MG, Malinin AI, Oshrine BR, Lowry DR, Sane DC, Tanguay JF, Steinhubl SR, Berger PB,
