ABSTRACT
Background Increased levels of the inflammatory biomarker high-sensitivityC-reactive protein predict cardiovascular events. Since statinslower levels of high-sensitivity C-reactive protein as wellas cholesterol, we hypothesized that people with elevated high-sensitivityC-reactive protein levels but without hyperlipidemia might benefitfrom statin treatment.
Methods We randomly assigned 17,802 apparently healthy men andwomen with low-density lipoprotein (LDL) cholesterol levelsof less than 130 mg per deciliter (3.4 mmol per liter) and high-sensitivityC-reactive protein levels of 2.0 mg per liter or higher to rosuvastatin,20 mg daily, or placebo and followed them for the occurrenceof the combined primary end point of myocardial infarction,stroke, arterial revascularization, hospitalization for unstableangina, or death from cardiovascular causes.
Results The trial was stopped after a median follow-up of 1.9years (maximum, 5.0). Rosuvastatin reduced LDL cholesterol levelsby 50% and high-sensitivity C-reactive protein levels by 37%.The rates of the primary end point were 0.77 and 1.36 per 100person-years of follow-up in the rosuvastatin and placebo groups,respectively (hazard ratio for rosuvastatin, 0.56; 95% confidenceinterval [CI], 0.46 to 0.69; P<0.00001), with correspondingrates of 0.17 and 0.37 for myocardial infarction (hazard ratio,0.46; 95% CI, 0.30 to 0.70; P=0.0002), 0.18 and 0.34 for stroke(hazard ratio, 0.52; 95% CI, 0.34 to 0.79; P=0.002), 0.41 and0.77 for revascularization or unstable angina (hazard ratio,0.53; 95% CI, 0.40 to 0.70; P<0.00001), 0.45 and 0.85 forthe combined end point of myocardial infarction, stroke, ordeath from cardiovascular causes (hazard ratio, 0.53; 95% CI,0.40 to 0.69; P<0.00001), and 1.00 and 1.25 for death fromany cause (hazard ratio, 0.80; 95% CI, 0.67 to 0.97; P=0.02).Consistent effects were observed in all subgroups evaluated.The rosuvastatin group did not have a significant increase inmyopathy or cancer but did have a higher incidence of physician-reporteddiabetes.
Conclusions In this trial of apparently healthy persons withouthyperlipidemia but with elevated high-sensitivity C-reactiveprotein levels, rosuvastatin significantly reduced the incidenceof major cardiovascular events. (ClinicalTrials.gov number,NCT00239681

.)
Current treatment algorithms for the prevention of myocardialinfarction, stroke, and death from cardiovascular causes recommendstatin therapy for patients with established vascular disease,diabetes, and overt hyperlipidemia.1,2 However, half of allmyocardial infarctions and strokes occur among apparently healthymen and women with levels of low-density lipoprotein (LDL) cholesterolthat are below currently recommended thresholds for treatment.
Measurement of high-sensitivity C-reactive protein, an inflammatorybiomarker that independently predicts future vascular events,improves global classification of risk, regardless of the LDLcholesterol level.3,4,5,6,7,8,9 We have previously shown thatstatin therapy reduces high-sensitivity C-reactive protein levels10,11and that among healthy persons,12 patients with stable coronarydisease,13 and those with the acute coronary syndrome,14,15,16the magnitude of the benefit associated with statin therapycorrelates in part with the achieved high-sensitivity C-reactiveprotein level. To date, however, no prospective outcome trialhas directly addressed the question of whether apparently healthypersons with levels of LDL cholesterol below current treatmentthresholds but with elevated levels of high-sensitivity C-reactiveprotein might benefit from statin therapy. The primary objectiveof the Justification for the Use of Statins in Prevention: anIntervention Trial Evaluating Rosuvastatin (JUPITER) was toinvestigate whether treatment with rosuvastatin, 20 mg daily,as compared with placebo, would decrease the rate of first majorcardiovascular events.
Methods
Trial Design
JUPITER was a randomized, double-blind, placebo-controlled,multicenter trial conducted at 1315 sites in 26 countries (seethe Supplementary Appendix, available with the full text ofthis article at www.nejm.org). The trial protocol was designedand written by the study chair and approved by the local institutionalreview board at each participating center. The trial data wereanalyzed by the academic study statistician and the academicprogrammer. The academic authors vouch for the accuracy andcompleteness of the data and the analyses.
The trial was financially supported by AstraZeneca. The sponsorcollected the trial data and monitored the study sites but playedno role in the conduct of the analyses or drafting of the manuscriptand had no access to the unblinded trial data until after themanuscript was submitted for publication.
Study Population
As described in detail elsewhere,17,18 men 50 years of age orolder and women 60 years of age or older were eligible for thetrial if they did not have a history of cardiovascular diseaseand if, at the initial screening visit, they had an LDL cholesterollevel of less than 130 mg per deciliter (3.4 mmol per liter)and a high-sensitivity C-reactive protein level of 2.0 mg perliter or more. Other requirements for inclusion were a willingnessto participate for the duration of the trial, provision of writteninformed consent, and a triglyceride level of less than 500mg per deciliter (5.6 mmol per liter).
Exclusion criteria were previous or current use of lipid-loweringtherapy, current use of postmenopausal hormone-replacement therapy,evidence of hepatic dysfunction (an alanine aminotransferaselevel that was more than twice the upper limit of the normalrange), a creatine kinase level that was more than three timesthe upper limit of the normal range, a creatinine level thatwas higher than 2.0 mg per deciliter (176.8 µmol per liter),diabetes, uncontrolled hypertension (systolic blood pressure>190 mm Hg or diastolic blood pressure >100 mm Hg), cancerwithin 5 years before enrollment (with the exception of basal-cellor squamous-cell carcinoma of the skin), uncontrolled hypothyroidism(a thyroid-stimulating hormone level that was more than 1.5times the upper limit of the normal range), and a recent historyof alcohol or drug abuse or another medical condition that mightcompromise safety or the successful completion of the study.Because a core scientific hypothesis of the trial concernedthe role of underlying low-grade inflammation as evidenced byelevated high-sensitivity C-reactive protein levels, patientswith inflammatory conditions such as severe arthritis, lupus,or inflammatory bowel disease were excluded, as were patientstaking immunosuppressant agents such as cyclosporine, tacrolimus,azathioprine, or long-term oral glucocorticoids.
All potentially eligible subjects underwent a 4-week run-inphase during which they received placebo. The purpose of thisphase was to identify a group of willing and eligible participantswho demonstrated good compliance (defined as the taking of morethan 80% of all study tablets) during that interval. Only subjectswho successfully completed the run-in phase were enrolled.
Trial Protocol
Eligible subjects were randomly assigned in a 1:1 ratio to receiveeither rosuvastatin, 20 mg daily, or matching placebo. Randomizationwas performed with the use of an interactive voice-responsesystem and was stratified according to center.
Follow-up visits were scheduled to occur at 13 weeks and then6, 12, 18, 24, 30, 36, 42, 48, 54, and 60 months after randomization.A closeout visit occurred after study termination. Follow-upassessments included laboratory evaluations, pill counts, andstructured interviews assessing outcomes and potential adverseevents. Measurements of lipid levels, high-sensitivity C-reactiveprotein levels, hepatic and renal function, blood glucose levels,and glycated hemoglobin values were performed in a central laboratory.Personnel at each site also contacted their participants midwaybetween scheduled visits to evaluate their well-being and tomaintain study participation.
End Points
The primary outcome was the occurrence of a first major cardiovascularevent, defined as nonfatal myocardial infarction, nonfatal stroke,hospitalization for unstable angina, an arterial revascularizationprocedure, or confirmed death from cardiovascular causes. Secondaryend points included the components of the primary end pointconsidered individually — arterial revascularization orhospitalization for unstable angina, myocardial infarction,stroke, or death from cardiovascular causes — and deathfrom any cause.
All reported primary end points that occurred through March30, 2008, were adjudicated on the basis of standardized criteriaby an independent end-point committee unaware of the randomizedtreatment assignments. Only deaths classified as clearly dueto cardiovascular or cerebrovascular causes by the end-pointcommittee were included in the analysis of the primary end point.For the end point of death from any cause, all deaths were included,regardless of whether data were available to confirm the causeof death.
Statistical Analysis
JUPITER was an event-driven trial designed to continue until520 confirmed primary end points had been documented, to providea statistical power of 90% to detect a 25% reduction in therate of the primary end point, with a two-sided significancelevel of 0.05. Pretrial estimates of the duration of follow-upand number of participants were based on event rates in earlierprevention trials19,20 and were modified to take into accountplans to include low-risk groups, including women.
The trial's prespecified monitoring plan called for two interimefficacy analyses with O'Brien–Fleming stopping boundariesdetermined by means of the Lan–DeMets approach. The stoppingboundary was crossed at the first prespecified efficacy evaluation,and on March 29, 2008, the independent data and safety monitoringboard voted to recommend termination of the trial. This recommendationtook into account the size and precision of the observed treatmentbenefit, as well as effects on the rates of death and othersecondary end points being monitored and on major subgroups.Although the trial ended on March 30, 2008, when the steeringcommittee formally accepted this recommendation, we continuedthe adverse-event reporting in a blinded manner for each studyparticipant until the date he or she appeared for a formal closeoutvisit and discontinued therapy.
All primary analyses were performed on an intention-to-treatbasis. Study participation was considered to be complete forany individual participant at the time he or she had an occurrenceof the primary end point, had informed consent withdrawn, wasunable to be followed further because the study site closed,or had been followed through at least March 30, 2008. The exposuretime was calculated as the time between randomization and thefirst major cardiovascular event, the date of death, the dateof the last study visit, the date of withdrawal or loss to follow-up,or March 30, 2008, whichever came first.
Cox proportional-hazards models were used to calculate hazardratios and 95% confidence intervals for the comparison of eventrates in the two study groups. Prespecified subgroup analyseswere performed according to the presence or absence of majorcardiovascular risk factors.
Results
Between February 4, 2003, and December 15, 2006, a total of89,890 people were screened for enrollment. Of these, 72,088were ineligible, including 37,611 (52.2%) with LDL cholesterollevels of 130 mg per deciliter or more and an additional 25,993(36.1%) with high-sensitivity C-reactive protein levels of lessthan 2.0 mg per liter. Other reasons for exclusion are presentedin Figure 1 in the Supplementary Appendix. A total of 17,802people were randomly assigned to a study group.
Baseline Characteristics
By design, the study population was diverse; 6801 of the 17,802participants were women (38.2%) and 4485 (25.2%) were blackor Hispanic (Table 1). Aspirin was used by 16.6% of participants,and 41.4% had the metabolic syndrome.21 In both the rosuvastatinand placebo groups, the median LDL cholesterol level was 108mg per deciliter (2.8 mmol per liter), the high-density lipoprotein(HDL) cholesterol level was 49 mg per deciliter (1.3 mmol perliter), and the triglyceride level was 118 mg per deciliter(1.3 mmol per liter); the high-sensitivity C-reactive proteinlevel was 4.2 and 4.3 mg per liter in the rosuvastatin and placebogroups, respectively.
Table 1. Baseline Characteristics of the Trial Participants, According to Study Group.
Compliance and Effects of Rosuvastatin on Lipids and High-Sensitivity C-Reactive Protein
At the time the study was terminated, 75% of participants weretaking their study pills. Among those assigned to rosuvastatin,the median LDL cholesterol level at 12 months was 55 mg perdeciliter (1.4 mmol per liter) (interquartile range, 44 to 72[1.1 to 1.9]), and the median high-sensitivity C-reactive proteinlevel was 2.2 mg per liter (interquartile range, 1.2 to 4.4)(Table 2). At the 12-month visit, the rosuvastatin group, ascompared with the placebo group, had a 50% lower median LDLcholesterol level (mean difference, 47 mg per deciliter [1.2mmol per liter]), a 37% lower median high-sensitivity C-reactiveprotein level, and a 17% lower median triglyceride level (P<0.001for all three comparisons). These effects persisted throughoutthe study period. At 12 months, the median HDL cholesterol levelwas 4% higher in the rosuvastatin group than in the placebogroup (P<0.001), but this effect was not present at the timeof study completion (P=0.34).
Table 2. Lipid and High-Sensitivity C-Reactive Protein Levels during the Follow-up Period, According to Study Group.
End Points
At the time of study termination (median follow-up, 1.9 years;maximal follow-up, 5.0 years), 142 first major cardiovascularevents had occurred in the rosuvastatin group, as compared with251 in the placebo group (Table 3). The rates of the primaryend point were 0.77 and 1.36 per 100 person-years of follow-upin the rosuvastatin and placebo groups, respectively (hazardratio for rosuvastatin, 0.56; 95% confidence interval [CI],0.46 to 0.69; P<0.00001) (Table 3 and Figure 1). In a testfor interaction between the study-group assignment and follow-uptime, there was no significant violation of the proportional-hazardsassumption.
Figure 1. Cumulative Incidence of Cardiovascular Events According to Study Group.
Panel A shows the cumulative incidence of the primary end point (nonfatal myocardial infarction, nonfatal stroke, arterial revascularization, hospitalization for unstable angina, or confirmed death from cardiovascular causes). The hazard ratio for rosuvastatin, as compared with placebo, was 0.56 (95% confidence interval [CI], 0.46 to 0.69; P<0.00001). Panel B shows the cumulative incidence of nonfatal myocardial infarction, nonfatal stroke, or death from cardiovascular causes, for which the hazard ratio in the rosuvastatin group was 0.53 (95% CI, 0.40 to 0.69; P<0.00001). Panel C shows the cumulative incidence of arterial revascularization or hospitalization for unstable angina, for which the hazard ratio in the rosuvastatin group was 0.53 (95% CI, 0.40 to 0.70; P<0.00001). Panel D shows the cumulative incidence of death from any cause, for which the hazard ratio in the rosuvastatin group was 0.80 (95% CI, 0.67 to 0.97; P=0.02). In each panel, the inset shows the same data on an enlarged y axis and on a condensed x axis.
On the basis of Kaplan–Meier estimates (Figure 1), thenumber of patients who would need to be treated with rosuvastatinfor 2 years to prevent the occurrence of one primary end pointis 95, and the number needed to treat for 4 years is 31. If4-year risks are projected over an average 5-year treatmentperiod, as has been commonly done in previous statin trialsaccording to the method of Altman and Andersen,22 the numberneeded to treat to prevent the occurrence of one primary endpoint is 25.
Rosuvastatin was also associated with significant reductionsin rates of the individual components of the primary trial endpoint. For the end point of fatal or nonfatal myocardial infarction,event rates were 0.17 and 0.37 per 100 person-years of follow-upin the rosuvastatin and placebo groups, respectively (hazardratio for rosuvastatin, 0.46; 95% CI, 0.30 to 0.70; P=0.0002).The corresponding rates were 0.18 and 0.34 for fatal or nonfatalstroke (hazard ratio, 0.52; 95% CI, 0.34 to 0.79; P=0.002),0.41 and 0.77 for arterial revascularization or unstable angina(hazard ratio, 0.53; 95% CI, 0.40 to 0.70; P<0.00001), and0.45 and 0.85 for the combined end point of nonfatal myocardialinfarction, nonfatal stroke, or death from cardiovascular causes(hazard ratio, 0.53; 95% CI, 0.40 to 0.69; P<0.00001).
In addition, the rates of death from any cause were 1.00 and1.25 per 100 person-years of follow-up in the rosuvastatin andplacebo groups, respectively (hazard ratio for the rosuvastatingroup, 0.80; 95% CI, 0.67 to 0.97; P=0.02) (Table 3 and Figure 1).In analyses limited to deaths for which the date of death wasknown with certainty, there was a similar reduction in the hazardratio associated with rosuvastatin (0.81; 95% CI, 0.67 to 0.98;P=0.03).
Subgroup Analyses
For the primary end point, there was no evidence of heterogeneityin the results for any subgroup evaluated. Relative hazard reductionsin the rosuvastatin group were similar for women (46%) and men(42%) and were observed in every subgroup evaluated, includingsubgroups according to age, race or ethnic group, region oforigin, status with regard to traditional risk factors, andFramingham risk score (Figure 2). Groups typically assumed tobe at very low risk also benefited. For participants who hadelevated levels of high-sensitivity C-reactive protein but whowere nonsmokers, were not overweight (had a body-mass index[the weight in kilograms divided by the square of the heightin meters] 25), did not have the metabolic syndrome, had a calculatedFramingham risk score of 10% or less, or had an LDL cholesterollevel of 100 mg per deciliter (2.6 mmol per liter) or lower,the observed relative reductions in the hazard ratio associatedwith rosuvastatin for the primary end point were similar tothose in higher-risk groups. For subjects with elevated high-sensitivityC-reactive protein levels but no other major risk factor otherthan increased age, the benefit of rosuvastatin was similarto that for higher-risk subjects (hazard ratio, 0.63; 95% CI,0.44 to 0.92; P=0.01).
Figure 2. Effects of Rosuvastatin on the Primary End Point, According to Baseline Characteristics.
The primary end point was the combination of nonfatal myocardial infarction, nonfatal stroke, arterial revascularization, hospitalization for unstable angina, or confirmed death from cardiovascular causes. The relative hazard ratios for rosuvastatin as compared with placebo are shown, with the size of each black square proportionate to the number of participants who had an occurrence of the primary end point in the subgroup; the horizontal lines indicate 95% confidence intervals. The dashed vertical line indicates the overall relative risk reduction for the complete trial cohort. Also shown are the P values for the test of an interaction between the primary end point and the categories within each subgroup. For the ordinal variables, interaction tests considered a trend across the subgroup categories with integer scores applied to these categories. Data were missing for some participants in some subgroups. The body-mass index (BMI) is the weight in kilograms divided by the square of the height in meters. CHD denotes coronary heart disease. The metabolic syndrome was defined according to 2005 consensus criteria of the American Heart Association and the National Heart, Lung, and Blood Institute.21 ATP-III risk factors refer to major risk factors, other than increased age, according to the Adult Treatment Panel III of the National Cholesterol Education Program. Race or ethnic group was self-reported.
Adverse Events
Total numbers of reported serious adverse events were similarin the rosuvastatin and placebo groups (1352 and 1377, respectively;P=0.60) (Table 4). Nineteen myopathic events were reported (in10 subjects receiving rosuvastatin and 9 receiving placebo,P=0.82). After closure of the trial, one nonfatal case of rhabdomyolysiswas reported in a 90-year-old participant with febrile influenza,pneumonia, and trauma-induced myopathy who was in the rosuvastatingroup (listed in Table 4).
Table 4. Monitored Adverse Events, Measured Laboratory Values, and Other Reported Events of Interest during the Follow-up Period.
There were no significant differences between the two studygroups with regard to muscle weakness, newly diagnosed cancer,or disorders of the hematologic, gastrointestinal, hepatic,or renal systems. With regard to direct measures of safety,rates of elevation of the alanine aminotransferase level tomore than three times the upper limit of the normal range weresimilar in the two groups. Median glomerular filtration ratesat 12 months were 66.8 and 66.6 ml per minute per 1.73 m2 ofbody-surface area in the rosuvastatin and placebo groups, respectively(P=0.02). Protocol-specified measurements showed no significantdifferences between the study groups during the follow-up periodwith respect to the fasting blood glucose level (98 mg per deciliter[5.4 mmol per liter] in both groups, P=0.12) or newly diagnosedglycosuria (in 36 subjects in the rosuvastatin group and 32in the placebo group, P=0.64); there was a minimal differencein the median glycated hemoglobin value (5.9% and 5.8%, respectively;P=0.001). Nevertheless, physician-reported diabetes was morefrequent in the rosuvastatin group (270 reports of diabetes,vs. 216 in the placebo group; P=0.01); these events were notadjudicated by the end-point committee. In contrast to the findingsin a previous study of high-dose statin therapy,23 we foundno significant between-group difference in the number of subjectswith intracranial hemorrhage (six in the rosuvastatin groupand nine in the placebo group, P=0.44).
Discussion
In this randomized trial of apparently healthy men and womenwith elevated levels of high-sensitivity C-reactive protein,rosuvastatin significantly reduced the incidence of major cardiovascularevents, despite the fact that nearly all study participantshad lipid levels at baseline that were well below the thresholdfor treatment according to current prevention guidelines. Rosuvastatinalso significantly reduced the incidence of death from any cause.These effects were consistent in all subgroups evaluated, includingsubgroups customarily considered to be at low risk, such aspeople with Framingham risk scores of 10% or less, those withLDL cholesterol levels of 100 mg per deciliter or less, thosewithout the metabolic syndrome, and those with elevated levelsof high-sensitivity C-reactive protein but no other major riskfactor. The trial also showed robust reductions in cardiovascularevents with statin therapy in women and black and Hispanic populationsfor which data on primary prevention are limited.
Previous statin trials (most of which used LDL cholesterol levelcriteria for enrollment) have generally reported a 20% reductionin vascular risk for each 1 mmol per liter (38.7 mg per deciliter)of absolute reduction in the LDL cholesterol level,24,25 aneffect that would have predicted a proportionate reduction inthe number of events in our study of approximately 25%. However,the reduction in the hazard seen in our trial, in which enrollmentwas based on elevated high-sensitivity C-reactive protein levelsrather than on elevated LDL cholesterol levels, was almost twicethis magnitude and revealed a greater relative benefit thanthat found in most previous statin trials (see Figure 2 in theSupplementary Appendix).
In this trial, myopathy, hepatic injury, and cancer did notoccur more frequently with rosuvastatin than with placebo, despitethe fact that LDL cholesterol levels below 55 mg per deciliterwere achieved in half the participants receiving rosuvastatin(and LDL cholesterol levels below 44 mg per deciliter in 25%).Since the median follow-up of subjects was 1.9 years, we cannotrule out the possibility that the rate of adverse events mightincrease in this population during longer courses of therapy.However, no such increase was detected in an analysis of participantswho continued to receive treatment for 4 or more years.
We did detect a small but significant increase in the rate ofphysician-reported diabetes with rosuvastatin, as well as asmall, though significant, increase in the median value of glycatedhemoglobin. Increases in glucose and glycated hemoglobin levels,the incidence of newly diagnosed diabetes, and worsening glycemiccontrol have been reported in previous trials of pravastatin,simvastatin, and atorvastatin.26,27 However, systematic protocol-specifiedmeasurements showed no significant difference between our twostudy groups in fasting blood glucose levels or glycosuria duringthe follow-up period. Therefore, although the increase in therate of physician-reported diabetes in the rosuvastatin groupcould reflect the play of chance, further study is needed beforeany causative effect can be established or refuted. Physicians'reports of diabetes were not adjudicated by the end-point committee,and careful evaluation of participants' records will be neededto better understand this possible effect.
Potential limitations of our study merit consideration. First,we did not include people with low levels of high-sensitivityC-reactive protein in our trial, since our hypothesis-generatinganalysis of high-sensitivity C-reactive protein in the Air Force/TexasCoronary Atherosclerosis Prevention Study (AFCAPS/TexCAPS)12showed extremely low event rates and no evidence that statintherapy lowered vascular risk among persons who had neitherhyperlipidemia nor elevated high-sensitivity C-reactive proteinlevels. Thus, a trial of statin therapy involving people withboth low cholesterol and low high-sensitivity C-reactive proteinlevels would have been not only infeasible in terms of statisticalpower and sample size but also highly unlikely to show a benefit.
Second, since the trial was stopped early by the independentdata and safety monitoring board after a median follow-up ofless than 2 years, the effect of longer-term therapy shouldbe considered. We verified that the assumption of proportionalhazards was not violated during the follow-up period, and wefound a robust benefit of rosuvastatin in analyses restrictedto events occurring more than 2 years after randomization. Thesefindings, as well as the demonstration that rates of hospitalizationand arterial revascularization were reduced by 47% within a2-year period, suggest that the strategy tested could be cost-effective.The strategy also could reduce the demand for imaging testsin asymptomatic populations. On the other hand, our trial evaluatedthe use of rosuvastatin for the prevention of first cardiovascularevents; therefore, the absolute event rates are lower than wouldbe expected among patients with a history of vascular disease,a fact that should be taken into account in considering whetherthe use of statin therapy among those with low LDL cholesterollevels but elevated high-sensitivity C-reactive protein levelswould be cost-effective if applied widely.
With regard to the inflammatory hypothesis of atherothrombosis,our trial involved an agent that is highly effective at reducinglevels of both cholesterol and high-sensitivity C-reactive protein.In previous work, achieving low levels of both LDL cholesteroland high-sensitivity C-reactive protein appears to have contributedto the clinical benefit of statin therapy.12,13,14,15,16 Giventhe recognition that atherothrombosis is in some respects adisorder of innate immunity,28 we hope the data presented herespur the further development of targeted antiinflammatory drugsas potential vascular therapeutic agents and lead to innovativetrials that can directly address whether the inhibition of inflammationby agents other than statins can reduce rates of vascular events.29
In conclusion, in this randomized trial of apparently healthymen and women who did not have hyperlipidemia but did have elevatedlevels of high-sensitivity C-reactive protein, the rates ofa first major cardiovascular event and death from any causewere significantly reduced among the participants who receivedrosuvastatin as compared with those who received placebo.
