RESUMEN

AIMS: Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors consistently reduce low-density lipoprotein cholesterol (LDL-C) by 50-60% and lipoprotein(a) (Lp(a)) by 20-30%, but the mechanism of Lp(a) lowering remains unclear. If Lp(a) is cleared by the LDL receptor, similar to LDL-C, then one would expect PCSK9 inhibition to induce a concordant LDL-C/Lp(a) response in an approximately 2:1 ratio. We aim to determine the prevalence of discordant plasma LDL-C/Lp(a) response to the PCSK9 inhibitor alirocumab. METHODS: This is a post hoc, pooled analysis of 10 randomized controlled trials from the ODYSSEY Phase 3 clinical trial program for alirocumab. Patients enrolled in the trials were high cardiovascular risk and/or with heterozygous familial hypercholesterolemia. The primary end point was prevalence of discordant LDL-C/Lp(a) response to alirocumab at 24 weeks. Discordant response was defined as LDL-C reduction >35% and Lp(a) reduction ≤10%, or LDL-C reduction ≤35% and Lp(a) reduction >10%. RESULTS: Of the 1709 patients in the pooled study cohort, 62.4% were male, and the mean age was 59.2 (SD: 11.0) years. Baseline mean LDL-C was 126.5 (SD: 46.3) mg/dL and baseline median Lp(a) was 46.9 (interquartile range: 21.8-89.0) mg/dL. Total prevalence of discordant LDL-C/Lp(a) response was 21.5% (12.6% with LDL-C >35% reduction and Lp(a) ≤10% reduction; 8.9% with LDL-C ≤35% reduction and Lp(a) >10% reduction). Baseline Lp(a) and familial hypercholesterolemia status did not affect discordance. CONCLUSION: A high prevalence of discordant LDL-C/Lp(a) response was observed with alirocumab, further suggesting that PCSK9 inhibitor therapy with alirocumab reduces plasma Lp(a) through alternative pathways to LDL receptor clearance.

RESUMEN

BACKGROUND: A better understanding of patterns in statin utilization and low-density lipoprotein cholesterol (LDL-C) among patients with atherosclerotic cardiovascular disease (ASCVD) in a clinical practice setting is needed. OBJECTIVES: The objective of this study was to examine statin utilization and LDL-C among new statin users with ASCVD. METHODS: This retrospective study used an electronic health record database from a community-based health care system. We identified ASCVD patients ≥21 years of age with a new statin prescription during the study period (2002-2016). Outcomes included high-intensity statin therapy (HIST) prescribing at treatment initiation, medication adherence (defined as proportion of days covered ≥0.80), statin therapy titrations rates, and changes in LDL-C during follow-up. RESULTS: Among 6199 eligible patients, mean follow-up was 16.8 months. At treatment initiation, 16.6% of patients received HIST. Approximately 53% of patients were adherent to statin regimens. Mean percent reduction in LDL-c was 25% during follow-up; 18% of patients, overall, and 30% of those initiating on HIST attained LDL-C reductions >50%. Rates of statin intensity-level increases were 8.4 per 100 person-years. HIST prescribing increased over time, beginning after generic atorvastatin availability and preceded treatment guidelines by two years. Initiation on HIST, higher adherence, and treatment intensification during follow-up were independent predictors of attaining LDL-C goals of <70 mg/dL or <100 mg/dL. CONCLUSIONS: In a community-based health care system, modest LDL-C lowering for secondary ASCVD prevention is likely driven by suboptimal adherence and low HIST prescribing and treatment intensification rates. Clinician and patient education are needed to reduce clinical inertia and improve medication adherence to better manage ASCVD.

RESUMEN

Current guidelines for hypercholesterolemia treatment emphasize lifestyle modification and lipid-modifying therapy to reduce the risk for cardiovascular disease. Statins are the primary class of agents used for the treatment of hypercholesterolemia. Although statins are effective for many patients, they fail to achieve optimal reduction in lipids for some patients, including those who have or are at high risk for cardiovascular disease. The PCSK9 gene was identified in the past decade as a potential therapeutic target for the management of patients with hypercholesterolemia. Pharmacologic interventions to decrease PCSK9 levels are in development, with the most promising approach using monoclonal antibodies that bind to PCSK9 in the plasma. Two monoclonal antibodies, alirocumab and evolocumab, have recently been approved for the treatment of hypercholesterolemia, and a third one, bococizumab, is in phase 3 clinical development. All 3 agents achieve significant reductions in levels of low-density lipoprotein cholesterol, as well as reductions in non-high-density lipoprotein cholesterol, apolipoprotein B, and lipoprotein(a). Long-term outcome trials are under way to determine the sustained efficacy, safety, and tolerability of PCSK9 inhibitors and whether this novel class of agents decreases the risk for major cardiovascular events in patients on lipid-modifying therapy. Available data suggest that PCSK9 inhibitors provide a robust reduction in atherogenic cholesterol levels with a good safety profile, especially for patients who fail to obtain an optimal clinical response to statin therapy, those who are statin intolerant or have contraindications to statin therapy, and those with familial hypercholesterolemia.

RESUMEN

An Expert Panel convened by the National Lipid Association previously developed a consensus set of recommendations for the patient-centered management of dyslipidemia in clinical medicine (part 1). These were guided by the principle that reducing elevated levels of atherogenic cholesterol (non-high-density lipoprotein cholesterol and low-density lipoprotein cholesterol) reduces the risk for atherosclerotic cardiovascular disease. This document represents a continuation of the National Lipid Association recommendations developed by a diverse panel of experts who examined the evidence base and provided recommendations regarding the following topics: (1) lifestyle therapies; (2) groups with special considerations, including children and adolescents, women, older patients, certain ethnic and racial groups, patients infected with human immunodeficiency virus, patients with rheumatoid arthritis, and patients with residual risk despite statin and lifestyle therapies; and (3) strategies to improve patient outcomes by increasing adherence and using team-based collaborative care.

RESUMEN

An estimated 25% of adults in the United States have elevated triglyceride (TG) levels. This is of particular concern given the evidence for a causal role of TG in the pathway of cardiovascular (CV) disease. Approved prescription omega-3 fatty acid products (RxOM3FAs) contain the long-chain fatty acids docosahexaenoic acid (DHA) and/or eicosapentaenoic acid (EPA) and are effective options for the treatment of high TG levels. RxOM3FAs that contain both EPA and DHA include omega-3-acid ethyl esters (ethyl esters of EPA and DHA; brand and generic products) and omega-3-carboxylic acids (free fatty acids primarily composed of EPA and DHA), while the RxOM3FA icosapent ethyl (the ethyl ester of EPA) contains EPA only. All RxOM3FA products produce substantial TG reduction and other beneficial effects on atherogenic lipid and inflammation-related parameters, blood pressure, and heart rate variability, but products that contain DHA may raise low-density lipoprotein-cholesterol (LDL-C). This commentary provides an overview of hypertriglyceridemia while summarizing the pharmacology, efficacy, and safety of prescription RxOM3FAs.

RESUMEN

Homozygous familial hypercholesterolemia (HoFH) is a rare, genetic disorder characterized by an absence or impairment of low-density lipoprotein receptor (LDLR) function resulting in significantly elevated low-density lipoprotein cholesterol (LDL-C) levels. The cholesterol exposure burden beginning in utero greatly increases the risk for atherosclerotic cardiovascular disease (ASCVD) and premature death. The genetic heterogeneity of HoFH results in a wide range of LDL-C levels among both untreated and treated patients. Diagnosis of HoFH should, therefore, be based on a comprehensive evaluation of clinical criteria and not exclusively LDL-C levels. As treatment goals, the European Atherosclerosis Society and International FH Foundation suggest target LDL-C levels of <100 mg/dL (<2.5 mmol/L) in adults or <70 mg/dL (<1.8 mmol/L) in adults with clinical coronary artery disease or diabetes. The National Lipid Association (NLA) recommends that LDL-C levels be reduced to <100 mg/dL (<2.5 mmol/L) or by at least ≥50 % from pretreatment levels. Conventional therapy combinations that lower atherogenic lipoproteins levels in the blood, such as statins, ezetimibe, bile acid sequestrants and niacin, as well as lipoprotein apheresis, are usually unable to reduce LDL-C levels to recommended targets. Two recently approved agents that reduce lipoprotein synthesis and secretion by the liver are lomitapide, a microsomal triglyceride transfer protein inhibitor, and mipomersen, an apolipoprotein B antisense oligonucleotide. The newly approved inhibitor of proprotein convertase subtilisin/kexin type 9 (PCSK9), evolocumab, also shows promise for the management of FH. Because of the extremely high risk for ASCVD, HoFH patients should be identified early.

RESUMEN

Hypertriglyceridemia affects approximately 33% of the US population. Elevated triglyceride levels are independently associated with cardiovascular disease (CVD) risk, and severe hypertriglyceridemia is a risk factor for acute pancreatitis. Guidelines for the management of severe hypertriglyceridemia (≥5.6 mmol/L [≥500 mg/dL]) recommend immediate use of triglyceride-lowering agents; however, statins remain the first line of therapy for the management of mild to moderate hypertriglyceridemia (1.7-5.6 mmol/L [150-499 mg/dL]). Statins primarily target elevated low-density lipoprotein cholesterol levels, but have also been shown to reduce mean triglyceride levels by up to 18% (or 43% in patients with triglyceride levels≥3.1 mmol/L [≥273 mg/dL]). However, individuals with hypertriglyceridemia may need additional reduction in triglyceride-rich lipoproteins and remnant particles to further reduce residual CVD risk. A number of guidelines recommend the addition of fibrates, niacin, or long-chain omega-3 fatty acids if elevated triglyceride or non-high-density lipoprotein cholesterol levels persist despite the use of high-intensity statin therapy. This review evaluates the impact of fibrates, niacin, and long-chain omega-3 fatty acids on lipid profiles and cardiovascular outcomes in patients with hypertriglyceridemia. It also assesses the adverse effects and drug-drug interactions associated with these triglyceride-lowering agents, because although they have all been shown to effectively reduce triglyceride levels in patients with hypertriglyceridemia, they differ with regard to their associated benefit-risk profiles. Long-chain omega-3 fatty acids may be a well-tolerated and effective alternative to fibrates and niacin, yet further large-scale clinical studies are required to evaluate their effects on cardiovascular outcomes and CVD risk reduction in patients with hypertriglyceridemia.

RESUMEN

BACKGROUND: Familial hypercholesterolemia (FH) is a common autosomal codominant disease characterized by extreme plasma cholesterol concentrations and high risk of early heart disease. FH is underdiagnosed and severely undertreated. This may be due in part to gaps in FH education within medical and pharmacy training programs. OBJECTIVES: To assess the extent to which FH is covered in professional curriculums in accredited schools and colleges of medicine, pharmacy, and osteopathic medicine in the United States. METHODS: An 18-question survey was distributed via e-mail to 288 US schools and colleges of medicine, pharmacy, and osteopathic medicine. RESULTS: Fifty-six of 288 (19.4%) programs responded to the survey. Three were excluded from analysis because of lack of program accreditation and FH instruction. Overall, 43% indicated that FH instruction at their respective institution was perceived to be adequate. More than 90% of the programs indicated that the following topics were covered within the curriculum: FH pathophysiology; associated morbidity and mortality; guideline-recommended low-density lipoprotein cholesterol goals and risk factor management; consequences of poor lipid management; and the screening, diagnosis, and treatment of adult patients. However, instruction was lacking for FH screening methods as one-third of the programs covered cascade screening and only half of the programs reported distinguishing between heterozygous and homozygous FH including differences in treatment approach. CONCLUSIONS: The results suggested important gaps in the coverage of FH in the curriculum, and strategies need to be developed to ensure that FH instruction is sufficient within these professional programs.

RESUMEN

The leadership of the National Lipid Association convened an Expert Panel to develop a consensus set of recommendations for patient-centered management of dyslipidemia in clinical medicine. An Executive Summary of those recommendations was previously published. This document provides support for the recommendations outlined in the Executive Summary. The major conclusions include (1) an elevated level of cholesterol carried by circulating apolipoprotein B-containing lipoproteins (non-high-density lipoprotein cholesterol and low-density lipoprotein cholesterol [LDL-C], termed atherogenic cholesterol) is a root cause of atherosclerosis, the key underlying process contributing to most clinical atherosclerotic cardiovascular disease (ASCVD) events; (2) reducing elevated levels of atherogenic cholesterol will lower ASCVD risk in proportion to the extent that atherogenic cholesterol is reduced. This benefit is presumed to result from atherogenic cholesterol lowering through multiple modalities, including lifestyle and drug therapies; (3) the intensity of risk-reduction therapy should generally be adjusted to the patient's absolute risk for an ASCVD event; (4) atherosclerosis is a process that often begins early in life and progresses for decades before resulting a clinical ASCVD event. Therefore, both intermediate-term and long-term or lifetime risk should be considered when assessing the potential benefits and hazards of risk-reduction therapies; (5) for patients in whom lipid-lowering drug therapy is indicated, statin treatment is the primary modality for reducing ASCVD risk; (6) nonlipid ASCVD risk factors should also be managed appropriately, particularly high blood pressure, cigarette smoking, and diabetes mellitus; and (7) the measurement and monitoring of atherogenic cholesterol levels remain an important part of a comprehensive ASCVD prevention strategy.

RESUMEN

Various organizations and agencies have issued recommendations for the management of dyslipidemia. Although many commonalities exist among them, material differences are present as well. The leadership of the National Lipid Association (NLA) convened an Expert Panel to develop a consensus set of recommendations for patient-centered management of dyslipidemia in clinical medicine. The current Executive Summary highlights the major conclusions in Part 1 of the recommendations report of the NLA Expert Panel and includes: (1) background and conceptual framework for formulation of the NLA Expert Panel recommendations; (2) screening and classification of lipoprotein lipid levels in adults; (3) targets for intervention in dyslipidemia management; (4) atherosclerotic cardiovascular disease risk assessment and treatment goals based on risk category; (5) atherogenic cholesterol-non-high-density lipoprotein cholesterol and low-density lipoprotein cholesterol-as the primary targets of therapy; and (6) lifestyle and drug therapies intended to reduce morbidity and mortality associated with dyslipidemia.

RESUMEN

One of the most serious challenges to all physicians is the maintenance of therapy for those chronic disorders that at present cannot be cured. Elevations of low-density lipoprotein and very low-density lipoprotein are among the most common of those disorders. We are now in an era in which 2 fundamental developments of modern technology have come together. These are the supply of effective and safe lipid-lowering drugs as well as the ability to closely monitor pertinent measures in our patients. The rapid conversion of our health care systems into large teams of professionals with direct support from third-party payers has made it possible to coordinate chronic care through electronic medical records and electronic communication. As a result, with effective planning and organization, we can guide our patients toward better adherence to successful medical regimens. These issues are evolving rapidly and have been presented in some detail in the December 2013 issue of the Journal. I was joined in this Roundtable discussion by 3 health professionals who have had extensive experience with the application of health information technology. They are Dr. Karen Aspry and Dr. Alan Brown, both clinical cardiologists, and Dr. Matthew Ito, a Doctor of Pharmacy.

RESUMEN

BACKGROUND: Drug interactions have been identified as a risk factor for muscle-related side effects in statin users. OBJECTIVES: The aim was to assess whether use of medications that inhibit cytochrome P450 (CYP450) isozymes, organic anion transporting polypeptide 1B1 (OATP1B1), or P-glycoprotein (P-gp) are associated with muscle-related symptoms among current and former statin users. METHODS: Persons (n = 10,138) from the Understanding Statin Use in America and Gaps in Education (USAGE) internet survey were categorized about whether they ever reported new or worsening muscle pain while taking a statin (n = 2935) or ever stopped a statin because of muscle pain (n = 1516). Univariate and multivariate logistic regression models were used to assess associations between use of concomitant therapies that inhibit CYP450 isozymes, OATP1B1, P-gp, or a combination and muscle-related outcomes. RESULTS: In multivariate analyses, concomitant use of a CYP450 inhibitor was associated with increased odds for new or worse muscle pain (odds ratio [OR] = 1.42; P < .001) or ever having stopped a statin because of muscle pain (OR = 1.28; P = .037). Concomitant use of medication known to inhibit both OATP1B1 and P-gp was also associated with increased odds (OR = 1.80; P = .030) of ever having stopped a statin because of muscle pain. CONCLUSIONS: Concomitant use of medication(s) that inhibit statin metabolism was associated with increased odds of new or worse muscle pain while taking a statin and having previously stopped a statin because of muscle symptoms. These data emphasize the importance of enhancing the capabilities of clinicians and health systems for identifying and reducing statin drug interactions.

RESUMEN

The workshop discussions focused on how low-density lipoprotein cholesterol (LDL-C) goal attainment can be enhanced with the use of health information technology (HIT) in different clinical settings. A gap is acknowledged in LDL-C goal attainment, but because of the passage of the American Recovery & Reinvestment Act and the Health Information Technology for Economic and Clinical Health Acts there is now reason for optimism that this gap can be narrowed. For HIT to be effectively used to achieve treatment goals, it must be implemented in a setting in which the health care team is fully committed to achieving these goals. Implementation of HIT alone has not resulted in reducing the gap. It is critical to build an effective management strategy into the HIT platform without increasing the overall work/time burden on staff. By enhancing communication between the health care team and the patient, more timely adjustments to treatment plans can be made with greater opportunity for LDL-C goal attainment and improved efficiency in the long run. Patients would be encouraged to take a more active role. Support tools are available. The National Lipid Association has developed a toolkit designed to improve patient compliance and could be modified for use in an HIT system. The importance of a collaborative approach between nongovernmental organizations such as the National Lipid Association, National Quality Forum, HIT partners, and other members of the health care industry offers the best opportunity for long-term success and the real possibility that such efforts could be applied to other chronic conditions, for example, diabetes and hypertension.

RESUMEN

BACKGROUND: Although statins have been shown to reduce cardiovascular disease mortality, less than half of U.S. adults achieve their low-density lipoprotein cholesterol goal. In many patients initiated on a statin, adherence rates decrease over time. OBJECTIVE: To characterize current and former statin users, identify reasons for the discontinuation or switching of statins, and identify factors associated with adherence. METHODS: The USAGE survey is a cross-sectional, self-administered Internet-based survey of 10,138 U.S. adults fielded September to October 2011. The following statin users were identified and compared: adherent nonswitchers, adherent switchers, non-adherent switchers, and discontinuers. Univariate and multivariate models using a priori covariates for adherence and discontinuation were examined. RESULTS: Most participants were current statin users who adhered with their prescribed statin (82.5%, n = 8371). Former statin users or discontinuers (12%, n = 1220) cited muscle pain, a side effect, as the primary reason for discontinuation (60%), followed by cost (16%), and then perceived lack of efficacy (13%). Discontinuers were less satisfied with their physicians' explanation of cholesterol treatment, more likely to use the Internet to research statins, and less likely to undergo frequent cholesterol monitoring. Among adherent statin users, the primary reasons for switching were muscle side effects (33%) and cost (32%). Individuals at risk for non-adherence included those with low household income, those who experienced muscle pain as a side effect while on statin therapy, and those taking medication for cardiovascular disease. CONCLUSION: Statin-related muscle side effects are common and contribute significantly to rates of discontinuation, switching, and non-adherence. Improved physician patient communication about side effects and benefits of statins are necessary to improve both adherence and outcomes.

RESUMEN

BACKGROUND: Statins significantly reduce cardiovascular events in a broad population of patients with hyperlipidemia. However, a small, but significant risk of new-onset diabetes has been reported in patients treated with statins. The mechanism by which statins cause diabetes has not been elucidated and therefore preventive strategies have yet to be defined. METHOD: Our goal was to study the differing effects of a lipophilic (simvastatin) statin, hydrophilic (pravastatin) statin, and ezetimibe on glucose transporter-4 (GLUT4) protein expression in 3T3-L1 adipocytes. We hypothesized that the reductions in GLUT4 protein secondary to statin treatment would be prevented when cells were co-incubated with coenzyme Q10 (CoQ10). GLUT4 protein expression was determined using the In-Cell Western technique. Confluent adipocytes were differentiated using a hormonal cocktail for 3 days; followed by treatment with simvastatin, pravastatin, ezetimibe and CoQ10. Cell morphology was observed after treatment using phase-contrast microscopy. RESULTS: Treatment with simvastatin (P<0.001) and simvastatin plus ezetimibe (P<0.001) significantly decreased GLUT4 protein expression in the adipocytes compared to control conditions. GLUT4 protein levels were similar to control after treatment with ezetimibe alone (P=0.52) or pravastatin (P=0.32). There was no significant difference (P=0.098) in GLUT4 protein levels after co-treatment with CoQ10 between any of the treatments and control conditions. CONCLUSION: Our studies have shown that lipophilic statins (simvastatin) reduce the GLUT4 protein levels in adipocytes, whereas hydrophilic statins (pravastatin) or ezetimibe do not. Co-treatment with CoQ10 appears to prevent the reduction in GLUT4 protein levels caused by simvastatin.

RESUMEN

BACKGROUND: Red yeast rice (RYR) is a commonly used dietary supplement for the management of dyslipidemia. In 2007, the Food and Drug Administration (FDA) issued a consumer warning to avoid RYR products because they may contain unauthorized drug (lovastatin) and also implemented Current Good Manufacturing Practices (CGMP) requiring that proper controls be in place by dietary supplement companies to ensure products are manufactured and processed in a consistent manner and produce high-quality products that are not adulterated with impurities or contaminants and are accurately labeled. OBJECTIVE: To assess the FDA oversight of companies manufacturing RYR products and review the labeled content of available RYR products. METHODS: The FDA was audited through the Freedom of Information Act, we requested answers to a series of questions concerning their oversight of companies manufacturing RYR products. The labeled content of each RYR product listed in the Natural Medicines Comprehensive Database (NMCD) was tabulated and summarized. Statin-related product warnings and if product certification and verification by an independent laboratory had been performed were documented. RESULTS: The FDA had no information on the number of RYR manufacturers and their compliance with CGMP regulations. A total of 101 products containing RYR were reviewed. No product could be confirmed as passing any independent laboratory verification testing. Nearly one-half (42.6%) of the RYR product labels contained statin-related warnings (ie, potential for muscle pain or weakness, etc). CONCLUSION: Currently, the FDA is not regulating manufacturers of RYR products and as a result, many of these products may contain monacolin K and toxins such as citrinin.

RESUMEN

BACKGROUND: Many patients drink café latte as part of their habitual morning routine to start their day and may be unable to skip this step before drawing a fasting blood sample for cholesterol testing. However, it is unknown what the acute effects of consuming a café latte are on fasting serum lipids just before blood sampling. OBJECTIVE: This was a prospective, open-label study with the primary objective of evaluating the acute effect of a 12-oz café latte (2% milk) on calculated low-density lipoprotein cholesterol (LDL-C) and secondary objectives of triglyceride, total cholesterol, high-density lipoprotein cholesterol (HDL-C), non-HDL-C, and fasting blood glucose (FBG). METHODS: A 10-hour fasting lipid profile was obtained before and 30 minutes after subjects consumed the café latte. RESULTS: Forty-nine adult participants (34 females; age [mean ± SD] 32.2 ± 13.2 years) were studied. No significant changes in total cholesterol, LDL-C, or non-HDL-C were observed after coffee consumption. Triglyceride significantly decreased from a median of 76.0 to 75.0 mg/dL (P = .002). HDL-C and FBG increased from a mean of 54.4 ± 12.7 to 56.4 ± 14.5 mg/dL (P = .015) and 87.2 ± 7.0 to 97.3 ± 12.9 mg/dL (P < .001), respectively. CONCLUSION: Consumption of 12 oz. of café latte within one hour of blood draw did not result in a significant change in LDL-C or non-HDL-C in young, nonobese healthy individuals. However, FBG levels increased by almost 12%.

RESUMEN

OBJECTIVE: To evaluate current approaches and explore emerging research related to dyslipidemia management. DATA SOURCES: MEDLINE (2004-April 2012) was searched for randomized controlled trials using the terms dyslipidemia and lipid-lowering therapy or statin (>1000 hits). Separate searches (MEDLINE, Google) identified meta-analyses (2010-2011), disease prevalence statistics, and current consensus guidelines (2004-July 2011). Additional references were identified from the publications reviewed. STUDY SELECTION AND DATA EXTRACTION: English-language articles on large multicenter trials were evaluated. DATA SYNTHESIS: National Cholesterol Education Program Adult Treatment Panel III guidelines for the reduction of cardiovascular risk recommend the attainment of specific low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol (non-HDL-C) target values, based on an individual's 10-year risk of coronary heart disease or global risk. For most patients unable to achieve recommended lipid level goals with therapeutic lifestyle changes, statins are the first option for treatment. Results of large, well-controlled clinical trials have demonstrated that statins are effective in primary and secondary prevention of cardiovascular disease in diverse populations, including patients with diabetes and the elderly, and that intensive statin therapy provides more effective lipid goal attainment and significantly greater risk reduction in patients with coronary artery disease. Statin therapy is generally well tolerated but may increase the risk of myopathy. Statin use has been associated with increases in hepatic transaminases and an increased risk of diabetes, although the absolute risk of diabetes is low compared with the risk reduction benefit. Combination therapy including a statin may be appropriate for certain populations, but the risk reduction benefits of combination therapy remain unclear. Ezetimibe is an important treatment option for patients with hypercholesterolemia who do not tolerate intensive statin therapy. Although fibrates or niacin improves overall lipid profiles in patients with hypertriglyceridemia or dyslipidemia who are receiving statin therapy, their efficacy in reducing cardiovascular risk remains questionable and their use raises safety and tolerability concerns. CONCLUSIONS: Intensifying lifestyle changes and statin dose should be utilized first in patients not achieving their LDL-C and non-HDL-C goals.

RESUMEN

BACKGROUND: Health information technology (HIT) offers a resource for public empowerment through tailored information. OBJECTIVE: Use interactive community health events to improve awareness of chronic disease risk factors while collecting data to improve health. METHODS: Let's Get Healthy! is an education and research program in which participants visit interactive research stations to learn about their own health (diet, body composition, blood chemistry). HIT enables computerized data collection that presents participants with immediate results and tailored educational feedback. An anonymous wristband number links collected data in a population database. RESULTS AND LESSONS LEARNED: Communities tailor events to meet community health needs with volunteers trained to conduct research. Participants experience being a research participant and contribute to an anonymous population database for both traditional research purposes and open-source community use. CONCLUSIONS: By integrating HIT with community involvement, health fairs become an interactive method for engaging communities in research and raising health awareness.
