They have been shown to provide significant benefit in individuals who have high cholesterol [Shepard J et al. \u003Cem\u003EN Engl J Med\u003C\/em\u003E 1995], as well as those who have average low-density lipoprotein (LDL) cholesterol levels [Downs JR et al. \u003Cem\u003EJAMA\u003C\/em\u003E 1998]. Subgroup analyses of data from the Air Force\/Texas Coronary Atherosclerosis Prevention Study (AFCAPS\/TEXCAPS) showed that individuals with metabolic syndrome and those who have lower high-density lipoprotein (HDL) cholesterol levels seem to have the greatest relative risk reduction Clearfield M et al. \u003Cem\u003EAm J Cardiol\u003C\/em\u003E 2005] and that those who had \u22652 risk factors benefitted more than those who had \u0026lt;2 risk factors [Gotto AM. \u003Cem\u003EAtherosclerosis Supplements\u003C\/em\u003E 2007]. We also have learned that there is a significant benefit from statins in individuals with multiple risk factors but relatively low LDL-cholesterol levels [Sever PS et al. \u003Cem\u003ELancet\u003C\/em\u003E 2003] and that decreasing events early on may very well have a positive effect on mortality later [Sever PS et al. \u003Cem\u003EEur Heart J\u003C\/em\u003E 2008].\u003C\/p\u003E\n         \u003Cp id=\u0022p-7\u0022\u003EAll of this evidence has shaped our approach to statin therapy and, according to Roger Blumenthal, MD, Johns Hopkins, Baltimore, MD, the recently released results of the JUPITER trial [Ridker PM et al. \u003Cem\u003EN Engl J Med\u003C\/em\u003E 2008] provide new information that will \u201cno doubt change our approach to using statins in primary prevention.\u201d\u003C\/p\u003E\n         \u003Cp id=\u0022p-8\u0022\u003EThe entry criteria for JUPITER were different from other cardiovascular primary prevention studies in several respects. LDL-cholesterol levels were lower (\u0026lt;130 mg\/dL vs a range of 131 to 192 mg\/dL in other trials), and JUPITER was unique in using a high-sensitivity C-reactive protein (hsCRP) level \u22652 mg\/L as an entry requirement. JUPITER also used a much more potent statin (rosuvastatin 20 mg) than those that were used in other trials.\u003C\/p\u003E\n         \u003Cp id=\u0022p-9\u0022\u003EImportant new questions that arise from JUPITER, noted Dr. Blumenthal, include whether hsCRP can help clinicians discriminate between who will benefit from statins and who will not and whether potent brand names or less potent generic statins are more cost-effective for lipid-lowering in primary prevention.\u003C\/p\u003E\n         \u003Cp id=\u0022p-10\u0022\u003EResults from the ILLUSTRATE trial [Nissen SE et al. \u003Cem\u003EN Engl J Med\u003C\/em\u003E 2007], which compared the effect of atorvastatin alone versus atorvastatin+torcetrapib on the progression of coronary atherosclerosis raised the question of whether raising HDL-cholesterol levels is always beneficial.\u003C\/p\u003E\n         \u003Cp id=\u0022p-11\u0022\u003EAlan M. Fogelman, MD, David Geffen School of Medicine at UCLA, Los Angeles, CA, discussed the relationship between HDL and inflammation, noting that this may be more useful than blood concentration when deciding whether or not to raise HDL levels.\u003C\/p\u003E\n         \u003Cp id=\u0022p-12\u0022\u003EIn the absence of systemic inflammation, when there is no acute phase response, HDL is anti-inflammatory; however, in the presence of systemic inflammation with an acute phase response, HDL is pro-inflammatory. The ability of HDL to inhibit or to enhance inflammation, lipid oxidation, plaque growth, and thrombosis reflects changes in specific enzyme and protein components [Watson KE et al. \u003Cem\u003ERev Cardiovasc Med\u003C\/em\u003E 2007]. Importantly, these changes in the inflammatory properties of HDL can occur independently of changes in HDL levels [Navab M et al. \u003Cem\u003ETrends Cardiovasc Med\u003C\/em\u003E 2005]; understanding them may lead to new diagnostic and therapeutic approaches to atherosclerosis and other inflammatory conditions.\u003C\/p\u003E\n         \u003Cp id=\u0022p-13\u0022\u003EThe HDL Inflammatory Index (HII) is a measure of the pro- or anti-inflammatory properties of an individual\u0027s HDL. It can be determined by comparing LDL-induced monocyte migration in an artery wall cell coculture assay with HDL from healthy controls. Studies have shown that the HII is better able to distinguish CHD patients from controls than HDL-cholesterol level [Ansell BJ et al. \u003Cem\u003ECirculation\u003C\/em\u003E 2003]. It also has been shown to correlate with poor outcomes in hemodialysis patients [Kalantar-Zadeh K et al. \u003Cem\u003EKidney Int\u003C\/em\u003E 2007].\u003C\/p\u003E\n         \u003Cp id=\u0022p-14\u0022\u003EIn closing, Dr. Fogelman noted that \u201cchanging HDL-cholesterol levels alone may not be enough.

Stein, MD, University of Wisconsin, Madison, WI, said that many doctors believe that \u201cit just makes sense\u201d that providing personalized biomarker or imaging results to patients would positively influence their adherence to treatment and their decision to engage in lifestyle changes. Several studies have attempted to determine whether this is the case. Although abnormal test results appear to influence clinician prescribing practices and appear to influence patient awareness of CVD risk, they do not seem to influence patient behavior in any consistent way [\u003Cem\u003EKorcarz CE et al.

In general, when both the threat appraisal and efficacy levels are high, individuals will accept a threat message and adopt a behavioral solution. However, when the threat appraisal is high and the efficacy appraisal is low, fear may lead to a cognitive solution, such as avoidance and rejection of the threat.\u003C\/p\u003E\n         \u003Cp id=\u0022p-17\u0022\u003EDr. Stein recommends further investigations that use visual feedback and psychological inventories and interventions to better assess the role of imaging in helping patients achieve preventive cardiology targets.\u003C\/p\u003E\n      \u003C\/div\u003E\u003Cul class=\u0022copyright-statement\u0022\u003E\u003Cli class=\u0022fn\u0022 id=\u0022copyright-statement-1\u0022\u003E\u00a9 2009 MD Conference Express\u003C\/li\u003E\u003C\/ul\u003E\u003Cspan class=\u0022highwire-journal-article-marker-end\u0022\u003E\u003C\/span\u003E\u003C\/div\u003E\u003Cspan id=\u0022related-urls\u0022\u003E\u003C\/span\u003E\u003C\/div\u003E\u003Ca href=\u0022http:\/\/mdc.sagepub.com\/content\/8\/8\/7.abstract\u0022 class=\u0022hw-link hw-link-article-abstract\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EView Summary\u003C\/a\u003E\u003C\/div\u003E  \u003C\/div\u003E\n\n  \n  \u003C\/div\u003E\n\u003C\/div\u003E\n  \u003C\/div\u003E\n\u003C\/div\u003E\n\u003C\/div\u003E\u003Cscript type=\u0022text\/javascript\u0022 src=\u0022http:\/\/mdc.sagepub.com\/sites\/all\/modules\/highwire\/highwire\/plugins\/highwire_markup_process\/js\/highwire_openurl.js?nzmly1\u0022\u003E\u003C\/script\u003E\n\u003Cscript type=\u0022text\/javascript\u0022 src=\u0022http:\/\/mdc.sagepub.com\/sites\/all\/modules\/highwire\/highwire\/plugins\/highwire_markup_process\/js\/highwire_tables.js?nzmly1\u0022\u003E\u003C\/script\u003E\n\u003C\/body\u003E\u003C\/html\u003E"}
