Abstract
Despite numerous improvements in the management of acute coronary syndrome(ACS), it is a major cause of mortality in India. Lipids play a critical role in pathogenesis of ACS and reduction of lipid parameters plays a pivotal role in secondary prevention. High total cholesterol and high low-density lipoprotein(LDL) are the major lipid abnormalities globally as well as in Indians. Among all the lipid parameters, LDL is the primary target of lipid-lowering therapies across the globe. High-dose statins, ezetimibe, proprotein convertase subtilisin/kexin type 9 inhibitors, and bempedoic acid are recommended therapies for LDL reduction in ACS patients. Statins have pleiotropic effects on the modulation of thrombogenesis, endothelial dysfunction, and myocardial protection. Multiple randomised controlled trials and meta-analyses have shown that the use of high-dose statin has significant benefits in ACS. LDL reduction goal is < 55 mg/dl or at least 50 % reduction from the baseline regardless of age or gender. Non-fasting LDL should be measured soon after the ACS as it varies minimally with food intake. The first line of therapy after ACS is to advise lifestyle modifications, combination therapy including high-dose statin with ezetimibe, and evaluation after 4-6 weeks of the index event. If the goal is not achieved then PCSK 9 inhibitors or Bempedoic acid should be used in combination with statins and ezetimibe to reduce recurrent ischaemic events. Despite the proven effect of these lipid-lowering therapies, undertreatment is still a big hurdle across the globe. Prohibitive costs, adverse effects, medication non-adherence, variation in health practice in different countries, and clinical inertia to prescribe this medication by physicians are the main reasons for the undertreatment.

Effect of More Intensive LDL-C-Lowering Therapy on Long-term Cardiovascular Outcomes in Early-Phase Acute Coronary Syndrome: A Systematic Review and Meta-analysis. Clin Ther 2021; 43:e217-e229. [PMID: 34092409 DOI: 10.1016/j.clinthera.2021.04.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2020] [Revised: 03/02/2021] [Accepted: 04/08/2021] [Indexed: 11/17/2022]
Abstract
PURPOSE The effect of more intensive LDL-C-lowering therapy (ILLT) on long-term cardiovascular outcomes during the early phase of acute coronary syndromes (ACSs) remains uncertain. We aimed to explore the influence of more intensive LDL-C-lowering therapyduring the early disease phase on long-term cardiovascular events among patients with ACSs. METHODS Randomized controlled trials that focused on the effect of more ILLT during early-phase ACSs on long-term major adverse cardiac events (MACEs) were searched in electronic databases (MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases) from database inception until November 23, 2019. The end points included the incidence of MACEs, myocardial infarction, stroke, revascularization, heart failure, and death events. Study risk of bias was assessed using the Cochrane Collaboration tools. Fixed- or random-effects models and meta-regression were performed to evaluate the association between baseline/proportional reduction of LDL-C levels during early-phase disease and the risk of end points using risk ratios with 95% CIs. FINDINGS A total of 53,199 participants were involved from 19 studies. The risk of MACEs decreased by 17% (95% CI, 0.76-0.90; P = 0.0012) for more intensive versus control therapy but varied by baseline and proportional reduction of LDL-C levels during early disease phase. The risk reduction of MACEs for more intensive versus control therapy among different subgroups was 26% (95% CI, 0.57-0.95; P = 0.06) with a baseline level >130 mg/dL, 23% (95% CI, 0.63-0.94; P = 0.02) with a baseline level of 100 to 130 mg/dL, and 10% (95% CI, 0.83-0.99; P = 0.07) with a baseline level <100 mg/dL. A significant difference of risk reduction for MACEs existed between patients treated with statin plus ezetimibe versus statin alone in the subgroup with a baseline level >130 mg/dL and proportional reduction >50%. Patients treated with more intensive therapy benefited from reduced risk of myocardial infarction, stroke, revascularization, and heart failure compared with control therapy. IMPLICATIONS More ILLT during early disease phase could significantly reduce the risk of long-term cardiovascular outcome in patients with ACSs. This benefit was most pronounced in patients with higher baseline and larger reduction of LDL-C levels in MACEs.

Abstract
BACKGROUND Nicotinic acid (niacin) is known to decrease LDL-cholesterol, and triglycerides, and increase HDL-cholesterol levels. The evidence of benefits with niacin monotherapy or add-on to statin-based therapy is controversial. OBJECTIVES To assess the effectiveness of niacin therapy versus placebo, administered as monotherapy or add-on to statin-based therapy in people with or at risk of cardiovascular disease (CVD) in terms of mortality, CVD events, and side effects. SEARCH METHODS Two reviewers independently and in duplicate screened records and potentially eligible full texts identified through electronic searches of CENTRAL, MEDLINE, Embase, Web of Science, two trial registries, and reference lists of relevant articles (latest search in August 2016). SELECTION CRITERIA We included all randomised controlled trials (RCTs) that either compared niacin monotherapy to placebo/usual care or niacin in combination with other component versus other component alone. We considered RCTs that administered niacin for at least six months, reported a clinical outcome, and included adults with or without established CVD. DATA COLLECTION AND ANALYSIS Two reviewers used pre-piloted forms to independently and in duplicate extract trials characteristics, risk of bias items, and outcomes data. Disagreements were resolved by consensus or third party arbitration. We conducted random-effects meta-analyses, sensitivity analyses based on risk of bias and different assumptions for missing data, and used meta-regression analyses to investigate potential relationships between treatment effects and duration of treatment, proportion of participants with established coronary heart disease and proportion of participants receiving background statin therapy. We used GRADE to assess the quality of evidence. MAIN RESULTS We included 23 RCTs that were published between 1968 and 2015 and included 39,195 participants in total. The mean age ranged from 33 to 71 years. The median duration of treatment was 11.5 months, and the median dose of niacin was 2 g/day. The proportion of participants with prior myocardial infarction ranged from 0% (4 trials) to 100% (2 trials, median proportion 48%); the proportion of participants taking statin ranged from 0% (4 trials) to 100% (12 trials, median proportion 100%).Using available cases, niacin did not reduce overall mortality (risk ratio (RR) 1.05, 95% confidence interval (CI) 0.97 to 1.12; participants = 35,543; studies = 12; I2 = 0%; high-quality evidence), cardiovascular mortality (RR 1.02, 95% CI 0.93 to 1.12; participants = 32,966; studies = 5; I2 = 0%; moderate-quality evidence), non-cardiovascular mortality (RR 1.12, 95% CI 0.98 to 1.28; participants = 32,966; studies = 5; I2 = 0%; high-quality evidence), the number of fatal or non-fatal myocardial infarctions (RR 0.93, 95% CI 0.87 to 1.00; participants = 34,829; studies = 9; I2 = 0%; moderate-quality evidence), nor the number of fatal or non-fatal strokes (RR 0.95, 95% CI 0.74 to 1.22; participants = 33,661; studies = 7; I2 = 42%; low-quality evidence). Participants randomised to niacin were more likely to discontinue treatment due to side effects than participants randomised to control group (RR 2.17, 95% CI 1.70 to 2.77; participants = 33,539; studies = 17; I2 = 77%; moderate-quality evidence). The results were robust to sensitivity analyses using different assumptions for missing data. AUTHORS' CONCLUSIONS Moderate- to high-quality evidence suggests that niacin does not reduce mortality, cardiovascular mortality, non-cardiovascular mortality, the number of fatal or non-fatal myocardial infarctions, nor the number of fatal or non-fatal strokes but is associated with side effects. Benefits from niacin therapy in the prevention of cardiovascular disease events are unlikely.

Abstract
BACKGROUND The early period following the onset of acute coronary syndrome (ACS) represents a critical stage of coronary heart disease, with a high risk of recurrent events and deaths. The short-term effects of early treatment with statins on patient-relevant outcomes in patients suffering from ACS are unclear. This is an update of a review previously published in 2011. OBJECTIVES To assess the effects, both harms and benefits, of early administered statins in patients with ACS, in terms of mortality and cardiovascular events. SEARCH METHODS We updated the searches of CENTRAL (2013, Issue 3), MEDLINE (Ovid) (1946 to April Week 1 2013), EMBASE (Ovid) (1947 to 2013 Week 14), and CINAHL (EBSCO) (1938 to 2013) on 12 April 2013. We applied no language restrictions. We supplemented the search by contacting experts in the field, by reviewing the reference lists of reviews and editorials on the topic, and by searching trial registries. SELECTION CRITERIA Randomized controlled trials (RCTs) comparing statins with placebo or usual care, with initiation of statin therapy within 14 days following the onset of ACS, follow-up of at least 30 days, and reporting at least one clinical outcome. DATA COLLECTION AND ANALYSIS Two authors independently assessed risk of bias and extracted data. We calculated risk ratios (RRs) for all outcomes in the treatment and control groups and pooled data using random-effects models. MAIN RESULTS Eighteen studies (14,303 patients) compared early statin treatment versus placebo or no treatment in patients with ACS. The new search did not identify any new studies for inclusion. There were some concerns about risk of bias and imprecision of summary estimates. Based on moderate quality evidence, early statin therapy did not decrease the combined primary outcome of death, non-fatal myocardial infarction, and stroke at one month (risk ratio (RR) 0.93, 95% confidence interval (CI) 0.80 to 1.08) or four months (RR 0.93, 95% CI 0.81 to 1.06) of follow-up when compared to placebo or no treatment. There were no statistically significant risk reductions from statins for total death, total myocardial infarction, total stroke, cardiovascular death, revascularization procedures, and acute heart failure at one month or at four months, although there were favorable trends related to statin use for each of these endpoints. Moderate quality evidence suggests that the incidence of unstable angina was significantly reduced at four months following ACS (RR 0.76, 95% CI 0.59 to 0.96). There were nine individuals with myopathy (elevated creatinine kinase levels more than 10 times the upper limit of normal) in statin-treated patients (0.13%) versus one (0.015%) in the control groups. Serious muscle toxicity was mostly limited to patients treated with simvastatin 80 mg. AUTHORS' CONCLUSIONS Based on moderate quality evidence, due to concerns about risk of bias and imprecision, initiation of statin therapy within 14 days following ACS does not reduce death, myocardial infarction, or stroke up to four months, but reduces the occurrence of unstable angina at four months following ACS. Serious side effects were rare.

Abstract
Background and Objectives The benefit of early statin treatment following acute myocardial infarction (MI) complicated with cardiogenic shock (CS) has not been well studied. We sought to assess the effect of early statin therapy in patients with CS complicating acute MI. Subjects and Methods We studied 553 statin-naive patients with acute MI and CS (Killip class IV) who underwent revascularization therapy between November 2005 and January 2008 at 51 hospitals in the Korea Acute Myocardial Infarction Registry. Patients were divided into 2 groups: those who received statins during hospitalization (n=280) and those who did not (n=273). The influence of statin treatment on a 12-month clinical outcome was examined using a matched-pairs analysis (n=200 in each group) based on the propensity for receiving statin therapy during hospitalization. Results Before adjustment, patients receiving statin, compared to those not receiving statin, had a more favorable clinical profile, were less likely to suffer procedural complications, and more likely to receive adequate medical therapy. Patients receiving statin had lower unadjusted in-hospital mortality and composite rate of mortality, MI, and repeat revascularization at 12 months, which remained significantly lower after adjustment for patient risk, procedural characteristics, and treatment propensity. Conclusion In CS patients with acute MI undergoing revascularization therapy, early statin treatment initiated during hospitalization was associated with lower rates of in-hospital death and 12-month adverse cardiac events.

Abstract
BACKGROUND Melanoma is the most lethal form of skin cancer, with an estimated 68,130 new cases and 8700 deaths in the United States in 2010. The increasing incidence and high death rate associated with metastatic disease support the need to focus on prevention. The authors used data from the Women's Health Initiative (WHI) to assess whether 3-hydroxy-3 methylglutaryl coenzyme A inhibitors (statins) are associated with a decreased risk of melanoma. METHODS The study population consisted of 119,726 postmenopausal white women, in which 1099 cases of malignant melanoma were identified over an average (± standard deviation) of 11.6 ± 3.2 years. All diagnoses were confirmed by medical record review and pathology reports. Information on statin use was collected at baseline and during follow-up. Self-administered and interview-administered questionnaires were used to collect information on other risk factors. Cox proportional hazards regression was used to calculate hazard ratios (HRs) with 95% confidence intervals (CIs). Analyses investigated the association of any statin use, type, potency, lipophilic status, and duration of use with melanoma. RESULTS Statins were used by 8824 women (7.4%) at baseline. The annualized rate of melanoma was 0.09% among statin users and 0.09% among nonusers The multivariable adjusted HR for statin users compared with nonusers was 1.14 (95% CI, 0.91-1.43). There were no significant differences in risk based on statin type, potency, category, duration, or in time-dependent models. CONCLUSIONS There was no significant association between statin use and melanoma risk among postmenopausal women in the WHI.

Abstract
BACKGROUND Statins are the most widely prescribed drug available. Due to this reason, it is important to understand the risks involved with the drug class and individual statins. AIM We conducted a meta-analysis and employed indirect comparisons to identify differing risk effects across statins. DESIGN We included any randomized clinical trial (RCT) of atorvastatin, fluvastatin, lovastatin, pitavastatin, pravastatin, rosuvastatin and simvastatin used for cardiovascular disease event prevention. The main outcome was adverse events [all-cause mortality, cancers, rhabdomylosis, diabetes, aspartate and alanine aminotransferase (AST/ALT), and creatinine kinase (CK) increases beyond the upper limit of normal]. In order to evaluate the relative effects of each drug on adverse events, we calculated adjusted indirect comparisons of the adverse-event outcomes. RESULTS Seventy-two trials involving 159,458 patients met our inclusion criteria. Overall, statin treatments significantly increased the rate of diabetes when compared to controls (OR: 1.09; 95% CI: 1.02-1.16) and elevated AST (OR: 1.31; 95% CI: 1.04-1.66) and ALT (OR: 1.28; 95% CI: 1.11-1.48) levels when compared to controls. Using indirect comparisons, we also found that atorvastatin significantly elevated AST levels compared to pravastatin (OR: 2.21; 95% CI: 1.13-4.29) and simvastatin significantly increased CK levels when compared to rosuvastatin (OR: 4.39; 95% CI: 1.01-19.07). Higher dose studies had increased risk of AST elevations. DISCUSSION Although statins are generally well tolerated, there are risks associated with almost all drugs. With few exceptions, statins appear to exert a similar risk across individual drugs.

Abstract
BACKGROUND The early period following the onset of acute coronary syndromes (ACS) represents a critical stage of coronary heart disease with a high risk for recurrent events and deaths. The short-term effects of early treatment with statins in patients suffering from ACS on patient-relevant outcomes are unclear. OBJECTIVES To assess the benefits and harms of early administered statins in patients with ACS from randomized controlled trials (RCTs). SEARCH STRATEGY We searched CENTRAL, MEDLINE, EMBASE, and CINAHL (to 1 February 2010). No language restrictions were applied. We supplemented the search by contacting experts in the field, by reviewing reference lists of reviews and editorials on the topic, and by searching trial registries. SELECTION CRITERIA RCTs comparing statins with placebo or usual care, initiation of statin therapy within 14 days following the onset of ACS, and follow-up of at least 30 days reporting at least one clinical outcome. DATA COLLECTION AND ANALYSIS Two authors independently assessed study quality and extracted data. We pooled treatment effects and calculated risk ratios (RRs) for all outcomes in the treatment and control groups using a random effects model. MAIN RESULTS Eighteen studies (14,303 patients) compared early statin treatment versus placebo or usual care in patients with ACS. Compared to placebo or usual care, early statin therapy did not decrease the combined primary outcome of death, non-fatal myocardial infarction (MI), and stroke at one month (risk ratio (RR) 0.93, 95% confidence interval (CI) 0.80 to 1.08) and four months (RR 0.93, 95% CI 0.81 to 1.06) of follow-up. There were no statistically significant risk reductions from statins for total death, total MI, total stroke, cardiovascular death, revascularization procedures, and acute heart failure at one month and at four months, although there were favorable trends related to statin use for each of these endpoints. The incidence of episodes of unstable angina was significantly reduced at four months following ACS (RR 0.76, 95% CI 0.59 to 0.96). There were nine individuals with myopathy (elevated creatinine kinase levels > 10 times the upper limit of normal) in statin treated patients (0.13%) versus one (0.015%) in the control groups. Serious muscle toxicity was mostly limited to patients treated with simvastatin 80 mg. AUTHORS' CONCLUSIONS Based on available evidence, initiation of statin therapy within 14 days following ACS does not reduce death, myocardial infarction, or stroke up to four months, but reduces the occurrence of unstable angina at four months following ACS.

Abstract
BACKGROUND The short-term effects of early statin therapy in acute coronary syndromes (ACS) on clinical outcomes remain unclear. Our objective was to update the evidence on patient relevant outcomes from all randomized trials comparing early statin therapy with placebo or usual care at 1 and 4 months following ACS. METHODS We performed a systematic review and meta-analysis of randomized trials that compared statins to control, initiated within 14 days after onset of ACS and with minimal follow-up of 30 days. Data were extracted in duplicate and analyzed by a random effects model. Investigators from individual trials contributed additional data where needed. RESULTS A total of 18 trials involving 14,303 patients with ACS were included in the meta-analysis. We found no evidence for further trials on the topic. Risk ratios for the combined endpoint of death, myocardial infarction, and stroke of early statin therapy compared to control were 0.93 (95% confidence interval [CI], 0.80-1.08; P=0.34) at 1 month and 0.93 (95% CI, 0.81-1.06; P=0.27) at 4 months following ACS. There were favorable trends related to statin use for all individual secondary endpoints but there was no statistically significant risk reduction except for unstable angina with a risk ratio of 0.76 (95% CI, 0.59-0.96; P=0.02) at 4 months following ACS. CONCLUSIONS Initiation of statin therapy within 14 days following ACS results in directionally favorable but non-significant reduction in death, myocardial infarction, or stroke up to 4 months, and significant reduction in the occurrence of unstable angina at 4 months following ACS.

Abstract
BACKGROUND Statins represent the largest selling class of cardiovascular drug in the world. Previous randomized trials (RCTs) have demonstrated important clinical benefits with statin therapy. AIM We combined evidence from all RCTs comparing a statin with placebo or usual care among patients with and without prior coronary heart disease (CHD) to determine clinical outcomes. DESIGN We searched independently, in duplicate, 12 electronic databases (from inception to August 2010), including full text journal content databases, to identify all statin versus inert control RCTs. We included RCTs of any statin versus any non-drug control in any populations. We abstracted data in duplicate on reported major clinical events and adverse events. We performed a random-effects meta-analysis and meta-regression. We performed a mixed treatment comparison using Bayesian methods. RESULTS We included a total of 76 RCTs involving 170,255 participants. There were a total of 14,878 deaths. Statin therapy reduced all-cause mortality, Relative Risk (RR) 0.90 [95% confidence interval (CI) 0.86-0.94, P ≤ 0.0001, I(2)=17%]; cardiovascular disease (CVD) mortality (RR 0.80, 95% CI 0.74-0.87, P<0.0001, I(2)=27%); fatal myocardial infarction (MI) (RR 0.82, 95% CI 0.75-0.91, P<0.0001, I(2)=21%); non-fatal MI (RR 0.74, 95% CI 0.67-0.81, P ≤ 0.001, I(2)=45%); revascularization (RR 0.76, 95% CI 0.70-0.81, P ≤ 0.0001); and a composite of fatal and non-fatal strokes (0.86, 95% CI 0.78-0.95, P=0.004, I(2)=41%). Adverse events were generally mild, but 17 RCTs reported on increased risk of development of incident diabetes [Odds Ratio (OR) 1.09; 95% CI 1.02-1.17, P=0.001, I(2)=11%]. Studies did not yield important differences across populations. We did not find any differing treatment effects between statins. DISCUSSION Statin therapies offer clear benefits across broad populations. As generic formulations become more available efforts to expand access should be a priority.

Abstract
The use of statins for secondary prevention after acute coronary syndrome is well established. In recent years, trials have investigated the dose of statins used and timing of administration. Initiation of statin therapy as early as 1 day after an acute coronary syndrome event has been shown to be effective in reducing major adverse cardiovascular events. The benefit of early statin use is linked to reduction in inflammation and increased compliance with therapy. In addition, intensive therapy further reduces events and inflammation, as reflected by decreased C-reactive protein. Given the findings of these recent studies, early and intensive lipid-lowering therapy with a statin is justified and safe.

Abstract
3-Hydroxy-3-methylglutary coenzyme A (HMG-CoA) reductase inhibitors have been shown to reduce cardiac events in different high-risk and medium-risk patient groups. Although there are other medications to lower cholesterol, evidence that these agents will provide protection from initial cardiac events is limited or does not exist. Also, although many physicians advocate combining second agents with statins to improve certain lipid fractions, evidence of improved reduction of initial cardiac events from these combinations is also lacking. Therefore, aggressive use of HMG-CoA reductase inhibitors remains the proven treatment to treat lipid abnormalities in primary patients.

Abstract
Managing dyslipidemia is an important part of the primary and secondary prevention of coronary heart disease. Low-density lipoprotein cholesterol reduction remains the primary lipid goal. Patients who have experienced an acute coronary syndrome (ACS) are at very high risk of recurrent adverse cardiovascular events. A growing body of literature supports the concept that early and intensive treatment with statins after an ACS event decreases recurrent adverse cardiovascular events. We review available evidence pertaining to lipid alterations in ACS.

Abstract
OBJECTIVE To date, statins have more often been considered a safe medication. However, with the wider use of statins, severe side effects have also been reported to occur in statin-treated patients, especially myositis and rhabdomyolysis. Currently, however, statin-associated tendon impairment has only been described anecdotally. The aim of this retrospective study was to evaluate tendon manifestations occurring in statin-treated patients. METHODS All reports in which a statin was listed spontaneously as a causative suspect medication of tendon complications in the network of the 31 French Pharmacovigilance Centers from 1990-2005 were included in this study. Data collection included patient characteristics and tendon adverse effects (time to onset of adverse effects, pattern, site of injury, and outcome). The percentage of the reports was further calculated for each statin. RESULTS Data were collected from 96 patients with a median age of 56 years; patients exhibited tendinitis (n = 63) and tendon rupture (n = 33). Tendinopathy more often occurred within the first year after statin initiation (59%). Tendon manifestations were related to atorvastatin (n = 35), simvastatin (n = 30), pravastatin (n = 21), fluvastatin (n = 5), and rosuvastatin (n = 5). Statin was reinitiated in 7 patients, resulting in recurrence of tendinopathy in all cases. CONCLUSION Our series suggests that statin-attributed tendinous complications are rare, considering the huge number of statin prescriptions. We suggest that prescribers should be aware of tendinous complications related to statins, particularly in risky situations, including physical exertion and association with medications known to increase the toxicity of statins.

Abstract
OBJECTIVE This study sought to determine if the initiation of statin (HMG-CoA reductase inhibitor) therapy during acute coronary syndromes reduces long-term mortality and other adverse cardiac outcomes. BACKGROUND Initiation of statin therapy during acute coronary syndromes has not been shown to reduce mortality, myocardial infarction or stroke within 4 months of follow-up. METHODS Clinical trials that randomized patients with acute coronary syndromes to early statin therapy compared with less intensive lipid reduction (placebo/lower-dose statin/usual care), and reported long-term outcomes were included for analysis. RESULTS In all, there were seven studies (L-CAD, PTT, FLORIDA, Colivicchi et al., PROVE-IT, ESTABLISH, and A-to-Z) with 9553 patients who started statin therapy within 12 days of hospital presentation. The incidence of all-cause mortality was 3.4% in the statin group versus 4.6% in the less intensive lipid reduction group over a weighted mean follow-up of 22.9 months (relative risk [RR] 0.74; 95% CI 0.61, 0.90; p = 0.003). The number of patients needed to treat to prevent one death was 84 patients. Similarly, the incidence of cardiovascular mortality in the statin versus the less intensive lipid reduction group was 2.4% versus 3.3% (RR 0.74; 95% CI 0.58, 0.93; p = 0.010), unstable angina 4.1% versus 5.0% (RR 0.81; 95% CI 0.68, 0.98; p = 0.027), revascularization 11.2% versus 12.9% (RR 0.86; 95% CI 0.78, 0.96; p = 0.006), stroke 1.1% versus 1.2% (RR 0.90; 95% CI 0.62, 1.30; p = 0.56), and myocardial infarction 6.6% versus 7.0% (RR 0.94; 95% CI 0.81, 1.09; p = 0.41). CONCLUSIONS The benefit of early initiation of statin therapy during acute coronary syndromes slowly accrues over time so that a survival advantage is seen around 24 months. Relatively few patients need to be treated to prevent one death over this time period. Furthermore, this approach significantly reduces unstable angina and the need for revascularization.

Abstract
It is widely assumed that acute benefit of statin therapy is mediated especially by non-lipid effects. The immediate influence of statins on lipid levels in patients with acute coronary syndrome (ACS) is, however, not clear. A total of 64 consecutive patients with ACS were randomized at admission to fluvastatin 80 mg (Group 1, N = 32) or standard therapy without statin (Group 2, N = 32). The levels of total cholesterol (TC), low-density-lipoprotein cholesterol (LDL-C), high-density-lipoprotein cholesterol (HDL-C), and triglycerides (TG) were examined at admission and after 24 h. Baseline characteristics were comparable in both groups. In Group 1, fluvastatin significantly decreased the levels of TC by 14.5%, LDL-C by 17.2%, and HDL-C by 10.0% (P < 0.001); TG were not influenced. In Group 2 only marginal reductions in TC (by 4.1%, P = 0.03) and HDL-C (by 7.5%, P < 0.01) were detected; the levels of LDL-C and TG were not changed. As compared with Group 2, in Group 1 the final levels of TC (P = 0.02) and LDL-C (P = 0.01) were significantly lower. Fluvastatin therapy, when started at admission in patients with ACS, significantly reduces TC and LDL-C already after 24 h. We suggest that the lipid-lowering effect of statins in the therapy of ACS is probably as prompt as non-lipid effects.

Abstract
Time may be an important variable when evaluating the efficacy of lipid-altering drugs. In this analysis of the Advicor Versus Other Cholesterol-Modulating Agents Trial Evaluation, niacin extended-release/lovastatin 1000/40 mg was as effective as atorvastatin 10 mg and more effective than simvastatin (both 10 mg and 20 mg) in achieving low-density lipoprotein cholesterol and non-high-density lipoprotein cholesterol treatment goals. The titration schedule for this study included the initiation of niacin-extended release/lovastatin 500/20 mg once a day for 4 weeks, titrated to the starting dose of 1000/40 mg after 4 weeks, and then titrated to the final dose of 2000/40 mg. The titration schedule for both atorvastatin and simvastatin was 10 mg per day for 8 weeks and then titrated to 40 mg per day. Using this schedule, 50% of niacin extended-release/lovastatin and atorvastatin patients reached low-density lipoprotein cholesterol and non-high-density lipoprotein cholesterol treatment goals within approximately 7 weeks, compared with simvastatin, in which 50% reached both treatment goals in 13-14 weeks. These time differences may have potential clinical relevance in reducing coronary heart disease risk.

Abstract
PURPOSE OF REVIEW Statins are effective lipid-lowering agents used extensively in medical practice. This review summarizes the evidence for statin treatment of cardiovascular patients in the intensive care unit and briefly discusses the role of statins in prevention and treatment of sepsis as a potential future application of statins in critical care. RECENT FINDINGS Recent studies have extended the use of statin therapy to the acute manifestations of cardiovascular disease and have suggested cholesterol-independent therapeutic benefits, termed pleiotropic effects, which have added a wide scope of potential targets for statin therapy. SUMMARY Statin therapy should be continued in intensive-care patients in whom statin therapy is warranted due to underlying cardiovascular disease or significant risk thereof. In acute coronary syndromes, statin therapy should be initiated within 24-96 h regardless of pretreatment cholesterol levels. Patients undergoing vascular surgery should receive peri-operative statin therapy. Placebo-controlled clinical trials are required to consolidate the experimental and observational evidence for prevention and treatment of sepsis.

Abstract
BACKGROUND Large randomized, controlled clinical trials of lovastatin and gemfibrozil for heart disease prevention have reported statistically significantly lower melanoma incidences in persons receiving these medications. Results of in vitro animal model and human case-control studies also suggest that statins and fibrates may reduce the risk of melanoma. METHODS We performed a systematic review of trials that randomly assigned participants to receive statins or fibrates versus an alternative therapy for a minimum of 6 months. Trials were identified by searching five electronic databases and the reference lists of eligible publications. Unpublished data were solicited from trial investigators and pharmaceutical companies. A meta-analysis was performed using a fixed-effects model, and odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to estimate pooled treatment effects. All statistical tests were two-sided. RESULTS We obtained data on incident melanomas from 20 of 36 qualifying randomized controlled trials (12 statin trials and eight fibrate trials), with a total of 70,820 participants. A total of 127 melanomas occurred among the 39,426 participants in the statin trials (59 among the 19,872 statin group participants and 68 among the 19,554 control group participants). A total of 27 melanomas occurred among the 31,394 participants enrolled in the fibrate trials (seven among the 12,324 fibrate group participants and 20 among the 19,070 control group participants). Overall, incidence of melanoma was not statistically significantly associated with the use of either statins (OR = 0.87, 95% CI = 0.61 to 1.23) or fibrates (OR = 0.45, 95% CI = 0.20 to 1.01). In a subgroup analysis by drug, only lovastatin use (in one trial) was statistically significantly associated with lower incidence of melanoma (OR = 0.52, 95% CI = 0.27 to 0.99). CONCLUSIONS These findings do not validate the possibility that statins or fibrates prevent melanoma.

Abstract
We investigated the effects of atorvastatin on inflammation and cardiac events during the inpatient period and initial 6-month follow-up in acute coronary syndrome (ACS) patients with low low-density lipoprotein (LDL) cholesterol level. One hundred and twelve consecutive ACS patients with LDL cholesterol less than 100 mg/dl were included in the study (mean 78.2+/-12.3 mg/dl). While 70 randomly selected patients received a dose of 40 mg atorvastatin within the first 24 h on top of their standard treatment as the atorvastatin group, the remaining 42 patients considered as the control group were given the standard treatment only, i.e., without any lipid-lowering drug therapy. Lipid profile, high-sensitivity C-reactive protein (hsCRP), and plasma amyloid A (SAA) levels were measured in all patients within the first 24 h of chest pain, on the 5th day, and in the 6th month. During the inpatient period and subsequent 6-month follow-up, all episodes of angina, reinfarction, revascularization, heart failure, rehospitalization, cardiac mortality, and total number of cardiac events were recorded. In the atorvastatin group, hsCRP and SAA values on the 5th day and in the 6th month compared to the first 24 h were significantly lower than those of the control group (P<0.0001). Mean LDL cholesterol level was significantly decreased in the atorvastatin group (55.7+/-17.7 mg/dl), but there was no significant change in the control group at the 6th month. The frequency of heart failure during the inpatient period and angina, unstable angina pectoris, heart failure, and revascularization in the first 6 months were also significantly reduced in the atorvastatin group. Atorvastatin started in the first 24 h reduces inflammation and improves the prognosis during both the inpatient period and the first 6 months of clinical follow-up in ACS patients with low LDL cholesterol levels.

Abstract
The long-term efficacy of statins for the primary and secondary prevention of coronary heart disease is well established; however, until recently, there was little trial-based evidence to support the early clinical benefit of these agents after acute coronary syndromes (ACS). This is particularly important as ACS is characterised by a high rate of recurrent early events in the first 6 months and (traditionally) lipid-lowering therapy was perceived to reduce coronary heart disease risk by lowering the significant risk of elevated cholesterol over many years. This paper reviews the current state of evidence from the key statin trials in ACS and their implications for the future management of ACS.

Abstract
Atherosclerosis is a systemic diffuse disease that may manifest as an anglographically localized coronary, cerebral, mesenteric, renal, and/or peripheral arterial stenosis or as diffuse atherosclerosis. While relief of organ ischemia is frequently possible with percutaneous or surgical revascularization, this in itself does not alleviate the long-term risks of disease recurrence or modify the metabolic derangements that promote atherosclerosis. It is critically important to recognize the need for treatment of dyslipidemia and to institute necessary therapies. The complex role of lipoprotein abnormalities is well understood and the use of lipid-lowering agents (90% statins) is reviewed in both primary and secondary prevention. The clinical interaction with novel risk factors and the practical problems in patient management are discussed.

Abstract
The background use of a number of established therapies presents a key challenge for the development of novel anti-atherosclerotic agents: how to predict potential efficacy before the completion of long-term trials with endpoints such as mortality. This challenge has stimulated the search to develop intermediate measures of efficacy. Recent advances now allow intravascular ultrasound (IVUS) to provide an accurate assessment of atheroma accumulation within the arterial wall. Here we describe how IVUS can be applied to the serial assessment of atheroma burden in response to treatment with a range of anti-atherosclerotic strategies, which has resulted in its emergence as a key technology in the evaluation and approval of novel drugs.

Abstract
Hospitalization and rehospitalization for acute coronary syndromes significantly contribute to the rising annual cost of healthcare. Despite growing evidence of the effectiveness of early and aggressive treatment of cardiovascular risk factors at the time of an acute event, eligible individuals are still not receiving adequate therapy. Inclusion of appropriate coronary artery disease treatments including lipid-lowering therapy at the time of hospitalization can lead to increased long-term compliance and reduced morbidity and mortality.

Abstract
BACKGROUND Secondary prevention of coronary artery disease is effective in reducing morbitiy and mortality. Our aim was to assess lipid management following non-attendance to a hospital based secondary prevention clinic. METHODS Data were collected over 5 years on statin usage and total cholesterol levels for patients with coronary artery disease following attendance at a cardiac nurse led outpatient clinic. Lipid levels were taken from a central laboratory database, for both patients discharged from clinic and non-attenders. RESULTS From 935 inpatients discharged from hospital, 248 (29%) defaulted from outpatient follow up. Lipid lowering drug usage was similar (72% vs. 74% for non-attenders, p=NS). Attenders at the nurse led outpatient clinic were more likely to achieve a total cholesterol <5 mmol/L at discharge than non-attenders (70% vs. 43%; p < 0.001), with a lower mean total cholesterol (4.75 +/- 0.06 mmol/L vs. 5.33 +/- 0.08 mmol/L; p < 0.001). Non-attenders subsequently had a greater number of cholesterol measurements than those who were discharged from the hospital based clinic (range 0-12, c2 23.8 on 12 df p < 0.005). Lipid profiles in hospital non-attenders remained inferior with fewer achieving a total cholesterol <5 mmol/L (61% vs. 78%; p < 0.001), and having greater mean total cholesterol levels (4.85 +/- 0.06 mmol/L vs. 4.52 +/- 0.05 mmol/L; p < 0.001). CONCLUSIONS Patients defaulting from hospital follow up have higher total cholesterols with fewer at target level compared to attenders. Though non-attenders receive subsequent lipid measurement, inferior lipid profiles persist compared to patients who completed hospital follow up to be discharged. Further implementation strategies are needed with regard to lipid management in this patient group.

Abstract
OBJECTIVES The aim of this study was to determine the relationship between atheroma regression and arterial wall remodeling. BACKGROUND Infusion of reconstituted high-density lipoprotein (rHDL) containing recombinant apolipoprotein A-I Milano (AIM) has been reported to promote rapid regression of coronary atherosclerosis. The current study analyzed intravascular ultrasound (IVUS) to define the changes that take place in the arterial wall that accompanied atheroma regression in this study. METHODS Forty-seven patients, ages 30 to 75 years, after an acute coronary syndrome were randomized to receive five weekly infusions of placebo or rHDL containing either low- or high-dose AIM. External elastic membrane (EEM) and lumen volumes were compared between coronary IVUS studies at baseline and follow-up. RESULTS In comparison with baseline, infusion of rHDL was associated with a 4.6% reduction in EEM volume. Lumen volume did not change. In 10-mm arterial subsegments with the greatest plaque burden at baseline, atheroma volume regressed by 10.9% with a similar reduction in EEM volume but with no change in lumen size. In contrast, EEM and atheroma volume did not change in the 10-mm segments containing the least plaque burden. The reduction in EEM in the most diseased segments was only apparent in subjects who underwent plaque regression. Reduction in EEM volume correlated with the decreased atheroma volume (r = 0.62), but there was no correlation between change in lumen size and change in plaque volume. CONCLUSIONS Remodeling of the arterial wall is a focal and heterogeneous process. After infusion of rHDL containing AIM, regression of coronary atherosclerosis is accompanied by reverse remodeling of the EEM, resulting in no change in luminal dimensions.

Abstract
In comparison to the general population, individuals with chronic kidney failure experience an increased risk for atherosclerotic cardiovascular disease attributed predominantly to pronounced abnormalities in lipid metabolism. The emerging consensus is that patients with chronic kidney failure should be treated aggressively for dyslipidemia. Statins reduce the risk of cardiovascular disease in a range of at-risk patients; this class of lipid-lowering drugs should be considered first-line treatment of dyslipidemia observed in renal disease patients. Although the statins share a common lipid-lowering effect, there are differences within this class of drugs. The statins differ in their pharmacokinetic effects, drug interaction profiles, and risk of myotoxicity. This article characterizes the dyslipidemia observed in the renal failure setting and reviews the therapeutic considerations involved in selecting among the statins. Lovastatin, simvastatin, pravastatin, fluvastatin, atorvastatin, and rosuvastatin are the available statins in the United States.

Abstract
We analysed the pharmaco-economics of the prospective peri-operative studies of statin administration for major elective vascular surgery, using the NHS reference costs for 2004. This analysis suggests that peri-operative statin therapy for patients undergoing vascular surgery may present the most cost-effective use of statin therapy yet described, with a number-needed-to-treat of 15 and almost 60% of the total cost of atorvastatin therapy recovered through a reduction in peri-operative adverse events.
