RESUMO

BACKGROUND: There has been a substantial increase in the use of laparoscopic sleeve gastrectomy (SG) to treat morbid obesity despite observational evidence demonstrating the superiority of Roux-en-Y gastric bypass (RYGB) for reducing low-density lipoprotein (LDL) cholesterol. The main aim was to ascertain whether high LDL cholesterol levels should be considered when selecting the most appropriate surgical procedure for each patient (RYGB or SG). METHODS: In this single-center, randomized clinical trial using intention-to-treat analysis, 38 patients with severe obesity and elevated levels of LDL cholesterol were randomly assigned to undergo RYGB or SG. The primary outcome was LDL cholesterol remission at 12 months, defined as LDL cholesterol < 3.36 nmol/l without lipid-lowering medications. Secondary outcomes included changes in weight, other comorbidities, qualitative lipoprotein traits, cholesterol esters, glycoproteins, cholesterol absorption and synthesis metabolites and complications. RESULTS: Intention-to-treat analysis revealed that LDL cholesterol remission occurred in 66.6% of RYGB patients compared to 27.8% of SG patients (p = 0.019). Among patients completing follow-up, RYGB demonstrated superior remission (80.0% vs. 29.4%, p = 0.005). Exclusive benefits of RYGB included a reduction in large, medium, and small LDL particles. Cholesterol absorption markers showed differential behavior after both techniques: campesterol (Δ -15.2 µg/mg, 95% CI -30.2 to -0.1) decreased after RYGB, and sitosterol (Δ 21.1 µg/mg, 95% CI 0.9 to 41.2), cholestanol (Δ 30.6 µg/mg, 95% CI 14.8 to 57.9) and campesterol (Δ 18.4 µg/mg, 95% CI 4.4 to 32.3) increased after SG. No differences in weight loss, cholesterol esters, glycoproteins, cholesterol synthesis metabolites or postoperative complications were observed between techniques. CONCLUSION: In conclusion, RYGB is superior to SG in terms of short-term of high LDL cholesterol remission. Furthermore, RYGB also led to a greater improvement in lipoprotein parameters that confer an atherogenic profile. Therefore, the presence of elevated levels of LDL cholesterol should be considered when determining the optimal bariatric surgery procedure for each patient.

RESUMO

Hypercholesterolemia, especially LDL-C («Low-Density-Lipoprotein - Cholesterol¼), is a major cardiovascular risk factor, especially for coronary artery disease. Patients at high or very high cardiovascular risk should reach LDL concentrations as low as possible («the lower, the better¼), with a reduction of at least 50 % from baseline levels according to the most recent guidelines, especially those in secondary prevention. An ezetimibe-statin combination most often allows to reach this goal thanks to a complementary action. The objectives of this article are to remind the dual actions of these two medications, to summarize the clinical evidence showing not only a remarkable cholesterol-lowering effect but also a reduction in cardiovascular events in both controlled trials and observational real-life studies, to specify the positioning of this combined oral therapy in the last international guidelines and to mention pharmaceutical specialties that combine ezetimibe with a statin available for the practitioner.


L'hypercholestérolémie, en particulier le LDL-C («Low-Density-Lipoprotein - Cholesterol¼), est un facteur de risque cardiovasculaire, notamment coronarien, majeur. Les patients à haut ou très haut risque cardiovasculaire doivent atteindre des concentrations de LDL les plus basses possibles (concept du «the lower, the better¼), avec une diminution d'au moins 50 % des valeurs de base selon les dernières recommandations, tout particulièrement ceux en prévention secondaire. Une combinaison ézétimibe-statine permet souvent d'atteindre cet objectif grâce à une action complémentaire. Le but de cet article est de rappeler la dualité des mécanismes d'action de ces deux approches, de résumer les évidences cliniques montrant non seulement un remarquable effet hypocholestérolémiant mais aussi une réduction des événements cardiovasculaires dans les essais cliniques et dans les études observationnelles de vraie vie, de préciser la position de cette combinaison thérapeutique orale dans les dernières recommandations internationales et de mentionner les spécialités pharmaceutiques associant l'ézétimibe à une statine mises à la disposition du praticien.

RESUMO

PURPOSE OF REVIEW: To provide an updated review of bempedoic acid's clinical application in lowering LDL-C in the setting of statin intolerance and the recent findings in the CLEAR Outcomes trial as well as summarize and synthesize the current state of knowledge regarding bempedoic acid while providing an in-depth analysis of the drug's pharmacological properties, mechanism of action, clinical trials, safety, and efficacy. RECENT FINDINGS: The CLEAR Outcomes trial has provided evidence to support bempedoic acid as a viable alternative to statins for the primary and secondary prevention of cardiovascular disease. Bempedoic acid is a promising treatment option for patients with hypercholesterolemia who are unable to tolerate statin therapy or require additional LDL-C reduction in the treatment of cardiovascular disease, with the newest lipid-lowering cardiovascular outcomes trials expanding on their generalizability particularly in the inclusion of women.

RESUMO

BACKGROUND: Persons with low socioeconomic status and nonwhite persons in the United States have high rates of cardiovascular disease. The use of combination pills (also called "polypills") containing low doses of medications with proven benefits for the prevention of cardiovascular disease may be beneficial in such persons. However, few data are available regarding the use of polypill therapy in underserved communities in the United States, in which adherence to guideline-based care is generally low. METHODS: We conducted a randomized, controlled trial involving adults without cardiovascular disease. Participants were assigned to the polypill group or the usual-care group at a federally qualified community health center in Alabama. Components of the polypill were atorvastatin (at a dose of 10 mg), amlodipine (2.5 mg), losartan (25 mg), and hydrochlorothiazide (12.5 mg). The two primary outcomes were the changes from baseline in systolic blood pressure and low-density lipoprotein (LDL) cholesterol level at 12 months. RESULTS: The trial enrolled 303 adults, of whom 96% were black. Three quarters of the participants had an annual income below $15,000. The mean estimated 10-year cardiovascular risk was 12.7%, the baseline blood pressure was 140/83 mm Hg, and the baseline LDL cholesterol level was 113 mg per deciliter. The monthly cost of the polypill was $26. At 12 months, adherence to the polypill regimen, as assessed on the basis of pill counts, was 86%. The mean systolic blood pressure decreased by 9 mm Hg in the polypill group, as compared with 2 mm Hg in the usual-care group (difference, -7 mm Hg; 95% confidence interval [CI], -12 to -2; P = 0.003). The mean LDL cholesterol level decreased by 15 mg per deciliter in the polypill group, as compared with 4 mg per deciliter in the usual-care group (difference, -11 mg per deciliter; 95% CI, -18 to -5; P<0.001). CONCLUSIONS: A polypill-based strategy led to greater reductions in systolic blood pressure and LDL cholesterol level than were observed with usual care in a socioeconomically vulnerable minority population.

RESUMO

BACKGROUND: Short-term studies have shown that bempedoic acid, an inhibitor of ATP citrate lyase, reduces levels of low-density lipoprotein (LDL) cholesterol. Data are limited regarding the safety and efficacy of bempedoic acid treatment in long-term studies involving patients with hypercholesterolemia who are receiving guideline-recommended statin therapy. METHODS: We conducted a randomized, controlled trial involving patients with atherosclerotic cardiovascular disease, heterozygous familial hypercholesterolemia, or both. Patients had to have an LDL cholesterol level of at least 70 mg per deciliter while they were receiving maximally tolerated statin therapy with or without additional lipid-lowering therapy. (Maximally tolerated statin therapy was defined as the highest intensity statin regimen that a patient was able to maintain, as determined by the investigator.) Patients were randomly assigned in a 2:1 ratio to receive bempedoic acid or placebo. The primary end point was safety, and the principal secondary end point (principal efficacy end point) was the percentage change in the LDL cholesterol level at week 12 of 52 weeks. RESULTS: The trial involved 2230 patients, of whom 1488 were assigned to receive bempedoic acid and 742 to receive placebo. The mean (±SD) LDL cholesterol level at baseline was 103.2±29.4 mg per deciliter. The incidence of adverse events (1167 of 1487 patients [78.5%] in the bempedoic acid group and 584 of 742 [78.7%] in the placebo group) and serious adverse events (216 patients [14.5%] and 104 [14.0%], respectively) did not differ substantially between the two groups during the intervention period, but the incidence of adverse events leading to discontinuation of the regimen was higher in the bempedoic acid group than in the placebo group (162 patients [10.9%] vs. 53 [7.1%]), as was the incidence of gout (18 patients [1.2%] vs. 2 [0.3%]). At week 12, bempedoic acid reduced the mean LDL cholesterol level by 19.2 mg per deciliter, representing a change of -16.5% from baseline (difference vs. placebo in change from baseline, -18.1 percentage points; 95% confidence interval, -20.0 to -16.1; P<0.001). Safety and efficacy findings were consistent, regardless of the intensity of background statin therapy. CONCLUSIONS: In this 52-week trial, bempedoic acid added to maximally tolerated statin therapy did not lead to a higher incidence of overall adverse events than placebo and led to significantly lower LDL cholesterol levels.

RESUMO

INTRODUCTION: Elevated levels of low-density lipoprotein (LDL) cholesterol have been unequivocally demonstrated to play a causal role in atherosclerotic cardiovascular disease. The last thirty years have witnessed a generation of clinical trials that have demonstrated a reduction in cardiovascular risk with the use of increasing intensive lipid lowering regimens involving statin therapy in combination with other agents. However, many patients fail to achieve treatment mandated LDL cholesterol goals. This highlights the need to develop additional approaches to lower LDL cholesterol levels. AREAS COVERED: (i) Contemporary data highlighting the atherogenicity of LDL cholesterol and cardiovascular benefits of current lipid lowering therapies. (ii) Importance of statin intolerance and inability to achieve LDL cholesterol goals in driving ongoing cardiovascular risk. (iii) Emergence of new therapeutic agents designed to achieve more effective lowering of LDL cholesterol. EXPERT OPINION: Effective lowering of LDL cholesterol plays a critical role in approaches to the prevention of cardiovascular disease. A greater number of patients will require combinations of agents to achieve optimal lipid control. Accordingly, new agents will be required to provide sufficient choice for patients at high cardiovascular risk.

RESUMO

Many patients do not achieve optimal low-density lipoprotein cholesterol (LDL-C) levels with statins alone; others are unable to tolerate statin therapy. Additional non-statin treatment options including ezetimibe, proprotein convertase subtilisin/kexin type 9 inhibitors, and bile acid sequestrants are often necessary to further reduce the risk of atherosclerotic cardiovascular disease. This review provides practical guidance as to the use of bempedoic acid to lower LDL-C and includes direction as to which patients may benefit and advice for safety monitoring during treatment. Bempedoic acid, a new class of agent, is a prodrug converted to bempedoyl-CoA by very long-chain acyl-CoA synthetase 1, an enzyme with high expression in the liver but that is undetectable in the skeletal muscle. Bempedoic acid inhibits the enzyme adenosine triphosphate (ATP)-citrate lyase, which lies two steps upstream from ß-hydroxy ß-methylglutaryl-CoA reductase in the cholesterol biosynthesis pathway. In clinical trials conducted in patients with or at risk for atherosclerotic cardiovascular disease or familial heterozygous hypercholesterolemia, bempedoic acid in combination with statins and/or ezetimibe significantly reduced LDL-C, apolipoprotein B, and high-sensitivity C-reactive protein compared with placebo. Bempedoic acid is generally well tolerated with no clinically meaningful increase in muscle-related symptoms relative to placebo, even in patients taking maximally tolerated statins. A small increase in serum uric acid (mean increase 0.8 mg/dL) is the most noteworthy adverse effect. Bempedoic acid provides an effective and generally well-tolerated medication to further reduce LDL-C in patients taking maximally tolerated statins or manage LDL-C levels in those who are unable to take statins. The potential for a reduced incidence of major cardiovascular events with bempedoic acid is being investigated in the CLEAR Outcomes trial, with results expected in 2023.

RESUMO

BACKGROUND: Strategies to improve patients' tolerance of and adherence to statins may enhance the effectiveness of dyslipidemia treatment in those at risk for cardiovascular disease (CVD). PURPOSE: To assess the benefits and harms of interventions to improve statin adherence in patients at risk for CVD. DATA SOURCES: MEDLINE, EMBASE, PubMed, and the Cochrane Library from December 2013 through May 2019 (English language only). STUDY SELECTION: Systematic reviews (SRs), randomized controlled trials (RCTs), and cohort studies that addressed interventions for improving statin tolerance and adherence. DATA EXTRACTION: One investigator abstracted data and assessed study quality, and a second investigator checked abstractions and assessments for accuracy. DATA SYNTHESIS: One SR, 1 RCT, and 4 cohort studies were included. The SR found that intensified patient care improved adherence and decreased levels of total serum cholesterol and low-density lipoprotein cholesterol (LDL-C) at 6 months or more of follow-up. Compared with statin treatment discontinuation, nondaily statin dosing lowered total cholesterol and LDL-C levels. One large cohort study suggested that more than 90% of patients who discontinued statin treatment could be rechallenged with the same or a different statin and be adherent 1 year after a statin-related adverse event led to discontinuation. Two small cohort studies reported that more than 90% of patients who were previously intolerant to statins and who had low baseline levels of vitamin D were able to adhere to statins 1 year after vitamin D supplementation. LIMITATION: This is a qualitative synthesis of new evidence with existing meta-analyses, and studies had several methodological shortcomings. CONCLUSION: Although the strength of evidence for most interventions was low or very low, intensified patient care and rechallenge with the same or a different statin (or a lower dose) seem to be favorable options for improving statin adherence.

RESUMO

Background and Objectives: Cardiovascular disease (CVD) is the leading cause of death globally and hypercholesterolemia is one of the major risk factors associated with CVD. Due to a growing body of research on side effects and long-term impacts of conventional CVD treatments, focus is shifting towards exploring alternative treatment approaches such as Ayurveda. However, because of a lack of strong scientific evidence, the safety and efficacy profiles of such interventions have not been well established. The current study aims to conduct a systematic review and meta-analyses to explore the strength of evidence on efficacy and safety of Ayurvedic herbs for hypercholesterolemia. Methods: Literature searches were conducted using databases including Medline, Cochrane Database, AMED, Embase, AYUSH research portal, and many others. All randomized controlled trials on individuals with hypercholesterolemia using Ayurvedic herbs (alone or in combination) with an exposure period of ≥ 3 weeks were included, with primary outcomes being total cholesterol levels, adverse events, and other cardiovascular events. The search strategy was determined with the help of the Cochrane Metabolic and Endocrine Disorders Group. Two researchers assessed the risk of each study individually and discrepancies were resolved by consensus or consultation with a third researcher. Meta-analysis was conducted using the inverse variance method and results are presented as forest plots and data summary tables using Revman v5.3. Results: A systematic review of 32 studies with 1386 participants found randomized controlled trials of three Ayurvedic herbs, Allium sativum (garlic), Commiphora mukul (guggulu), and Nigella sativa (black cumin) on hypercholesterolemia that met inclusion criteria. The average duration of intervention was 12 weeks. Meta-analysis of the trials showed that guggulu reduced total cholesterol and low-density lipoprotein levels by 16.78 mg/dL (95% C.I. 13.96 to 2.61; p-value = 0.02) and 18.78 mg/dL (95% C.I. 34.07 to 3.48; p = 0.02), respectively. Garlic reduced LDL-C by 10.37 mg/dL (95% C.I. -17.58 to -3.16; p-value = 0.005). Black cumin lowered total cholesterol by 9.28 mg/dL (95% C.I. -17.36, to -1.19, p-value = 0.02). Reported adverse side effects were minimal. Conclusion: There is moderate to high level of evidence from randomized controlled trials that the Ayurvedic herbs guggulu, garlic, and black cumin are moderately effective for reducing hypercholesterolemia. In addition, minimal evidence was found for any side effects associated with these herbs, positioning them as safe adjuvants to conventional treatments.

RESUMO

Acute respiratory distress syndrome (ARDS) is a devastating clinical manifestation of COVID-19 pneumonia and is mainly based on an immune-driven pathology. Mounting evidence suggests that COVID-19 is fueled by a maladaptive host inflammatory response that involves excessive activation of innate immune pathways. While a "cytokine storm" involving IL-6 and other cytokines has been documented, complement C3 activation has been implicated as an initial effector mechanism that exacerbates lung injury in preclinical models of SARS-CoV infection. C3-targeted intervention may provide broader therapeutic control of complement-mediated inflammatory damage in COVID-19 patients. Herein, we report the clinical course of a patient with severe ARDS due to COVID-19 pneumonia who was safely and successfully treated with the compstatin-based complement C3 inhibitor AMY-101.

RESUMO

Atherosclerotic cardiovascular disease (ASCVD) is associated with significant morbidity and mortality worldwide. Increased serum levels of low-density lipoprotein cholesterol (LDL-C) are an independent risk factor for ASCVD, and clinical trial data have shown that lowering LDL-C generally reduces cardiovascular risk. Until recently, 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors (statins) have been the main therapy for lowering LDL-C. However, some statin-treated patients have persistently elevated residual cardiovascular risk due to inadequate lowering of LDL-C levels or non-LDL-related dyslipidemia. In addition, adverse effects of statins may limit their tolerability and therefore the ability to attain effective doses in some patients. A new class of drugs that inhibit proprotein convertase subtilisin-kexin type 9 (PCSK9) has been developed to treat hyperlipidemia. This review discusses the history and mechanism of action of PCSK9 inhibitors, their metabolic effects, and clinical outcomes associated with these medications, highlighting recent large cardiovascular outcome trials investigating these therapies.

RESUMO

PURPOSE OF REVIEW: Statins represent the cornerstone for the treatment of hypercholesterolemia, although muscle-related side effects and dysregulation of glucose metabolism have strongly limited their adherence and compliance especially in primary prevention therapy. The purpose of the present review is to provide the most recent evidence of the efficacy and safety of statins in monotherapy or combination with new lipid-lowering drugs. RECENT FINDINGS: Recent "life-long" analysis conducted on young familial hypercholesterolemia patients, elderly hypocholesterolemic subjects, and from a 20-year follow-up of randomized controlled trial (RCT) have been published confirming that the cardiovascular benefits of statin therapy, in patients for whom it is recommended by current guidelines, greatly outweigh the risks of side effects. In addition, recent therapies to be used in combination with statins have shown to increase the percentage of patients at goal for low-density lipoprotein - cholesterol (LDL-C) with a good safety profile. The cardiovascular (CV) benefits of monoclonal antibodies anti-proprotein convertase subtilisin/kexin type 9 (PCSK9) and ezetimibe, in patients under statin therapy, have been proven by specific RCT, while we are still waiting for the results of bempedoic acid and the small-interfering RNA (si-RNA) anti-PCSK9 inclisiran. Taken together, the approval of new pharmacological agents to be used in combination with statins represents the future for a tailored therapy of cardiovascular disease patients.

RESUMO

AIM: To compare the efficacy and safety of colesevelam and ezetimibe as second-line low density lipoprotein-cholesterol (LDL-c)-lowering options in type 2 diabetes (T2D). MATERIALS AND METHODS: GOAL-RCT is a 24-week, open-label, randomized, pragmatic clinical trial. Subjects with T2D with uncontrolled HbA1c (7.1%-10%) and LDL-c (>2.0 mmol/L) were randomized 1:1 to colesevelam 3.75 g or ezetimibe 10 mg daily. The primary composite outcome was the proportion of participants achieving an LDL-c target of ≤2.0 mmol/L and HbA1c target of ≤7.0%. Intention to treat analysis was performed. RESULTS: Two hundred subjects were enrolled: mean age 59 ± 10 years; mean HbA1c 8.0%; mean LDL-c 2.5 mmol/L; 97% on statin therapy. The primary composite outcome was achieved by similar proportions of participants with colesevelam (14.6%) and ezetimibe (10.5%) (Pnon-inferiority < .001, Psuperiority = .41). LDL-c reduction from baseline was less with colesevelam compared with ezetimibe (14.0% vs. 23.2%, P < .01), as was the proportion of subjects achieving an LDL-c target of ≤2.0 mmol/L (47.6% and 67.0%, respectively; P = .007). Mean HbA1c was reduced with colesevelam (-0.26 ± 0.10%), while no change was observed with ezetimibe (difference P = .06). Adverse events and discontinuation rates were higher for colesevelam (20.2% and 31.1%) compared with ezetimibe (7.2% and 6.2%), respectively. CONCLUSIONS: Among subjects with T2D, the initiation of colesevelam or ezetimibe led to similar achievement of primary composite outcome (LDL-c and HbA1c within target), with ezetimibe recording a greater LDL-c reduction and better tolerability than colesevelam.

RESUMO

BACKGROUND: Several studies have investigated the association between non-statin lipid-lowering therapy and regression of atherosclerosis. However, these studies were mostly small and their results were not always robust. The objectives were: (1) to define if a dual lipid-lowering therapy (statin + non-statin drugs) is associated with coronary atherosclerosis regression, estimated by intravascular ultrasound (IVUS); (2) to assess the association between dual lipid-lowering-induced changes in low density lipoprotein cholesterol (LDL-C) and non-high-density-lipoprotein cholesterol (non-HDL-C) levels and atherosclerosis regression. METHODS: A meta-analysis including trials of non-statin lipid-lowering therapy, reporting LDL-C, non-HDL-C and total atheroma volume (TAV) with a minimum of 6 months of follow-up was performed. The primary endpoint was defined as the change in TAV measured from baseline to follow-up, comparing groups of subjects on statins alone versus combination of statin and non-statin drugs. The random-effects model and meta-regression were performed. RESULTS: Eight eligible trials of non-statin lipid-lowering drugs (1759 patients) were included. Overall, the dual lipid-lowering therapy was associated with a significant reduction in TAV [- 4.0 mm3 (CI 95% -5.4 to - 2.6)]; I2 = 0%]. The findings were similar in the stratified analysis according to the lipid-lowering drug class (ezetimibe or PCSK9 inhibitors). In the meta-regression, a 10% decrease in LDL-C or non-HDL-C levels, was associated, respectively, with 1.0 mm3 and 1.1 mm3 regressions in TAV. CONCLUSION: These data suggests the addition of ezetimibe or PCSK9 inhibitors to statin therapy results in a significant regression of TAV. Reduction of coronary atherosclerosis observed with non-statin lipid-lowering therapy is associated to the degree of LDL-C and non-HDL-C lowering. Therefore, it seems reasonable to achieve lipid goals according to cardiovascular risk and regardless of the lipid-lowering strategy used (statin monotherapy or dual treatment).

RESUMO

BACKGROUND: The VOYAGER meta-analysis reported on the low-density lipoprotein cholesterol (LDL-C)-lowering effect of commonly used statins in Caucasian subjects. As there is limited literature available on the efficacy of statins in Asian populations, the current meta-analysis compared the effects of rosuvastatin and atorvastatin on LDL-C levels in an East Asian population. METHODS: The MEDLINE, PubMed, Embase, Cochrane Library, and Web of Science databases were searched for randomized controlled trials comparing lipid-lowering effects of rosuvastatin and atorvastatin in an East Asian population. Data on the study design, participant characteristics, and outcomes were extracted. Odds ratios (OR), weighted mean differences (WMD), or standardized mean differences were calculated using the random-effects model. RESULTS: The meta-analysis comprised 16 randomized controlled trials with 5930 participants. Compared with atorvastatin, patients treated with rosuvastatin had a significant reduction in LDL-C: WMD = -7.15 mg/dl (95% confidence intervals [CI]: -10.71--3.60) mg/dl, p < 0.0001. Meta-regression analyses revealed no significant association between the superior benefits of rosuvastatin and other variables including age, sex, baseline LDL-C level, and follow-up duration. Additionally, the rosuvastatin group of patients, who were treated with half the dose of atorvastatin, achieved a significantly greater reduction in LDL-C levels (WMD = -3.57; 95% CI: -5.40--1.74 mg/dl, p < 0.001). Both rosuvastatin and atorvastatin were well tolerated, with similar incidences of adverse events. CONCLUSION: Similar to the VOYAGER meta-analysis, which reported a greater efficacy of rosuvastatin in comparison with atorvastatin and simvastatin in Caucasian patients, we found that the efficacy of rosuvastatin was superior to atorvastatin in East Asian patients with hypercholesterolemia.

RESUMO

LDL cholesterol targets are increasingly strict in recent international guidelines, especially in patients at very high or high cardiovascular risk. To reach these targets, it is recommended to use a potent statin, with a titration up to the maximal tolerated dose and, if not sufficient, to combine ezetimibe, a medication that blocks the intestinal absorption of cholesterol. This association allows reduce the dose of statin, while keeping an excellent cholesterol-lowering efficacy and favouring a good tolerance profile. This article describes the characteristics of a fixed-dose combination of rosuvastatin, the most potent statin, and ezetimibe, commercialized in Belgium under the trade name Myrosor®.


Les cibles de cholestérol LDL à atteindre sont de plus en plus basses dans les dernières recommandations internationales, en particulier chez les patients à très haut ou à haut risque cardiovasculaire. Pour les atteindre, il est recommandé de recourir à une statine puissante, en utilisant la dose maximale tolérée et, si insuffisant, en la combinant à un agent inhibant l'absorption intestinale de cholestérol, l'ézétimibe. Cette association permet de réduire la dose de statine, tout en gardant une excellente efficacité hypocholestérolémiante et en favorisant un bon profil de tolérance. Cet article décrit les caractéristiques d'une combinaison fixe de rosuvastatine, la statine la plus puissante, et de l'ézétimibe, commercialisé en Belgique sous le nom de Myrosor®.

RESUMO

Cholesterol-lowering statin medications are a safe and effective therapy to lower cholesterol and reduce the risk of cardiovascular events. Yet physician prescribing patterns and patient adherence remain suboptimal in Canada and the United States, often due to pervasive misconceptions. The Community Heart Outcomes Improvement and Cholesterol Education Study (CHOICES) is a pragmatic, registry-based, cluster randomized controlled trial that aims to improve cholesterol management through appropriate statin use in adults and to ultimately reduce cardiovascular events in high-risk communities across Ontario. The trial uses an innovative, multicomponent intervention and implementation approach that includes audit and feedback reports for family physicians and educational materials and tools for patients.

RESUMO

PURPOSE OF REVIEW: The use of therapeutic monoclonal antibodies to target proprotein convertase subtilisin/kexin type 9 (PCSK9) represents a novel approach to the management of hypercholesteremia and prevention of atherosclerotic cardiovascular disease. We review the most recent literature relevant to PCSK9 inhibition with emphasis on how recent results and ongoing trials have and will continue to shape the use of this new therapeutic class in preventive cardiology. RECENT FINDINGS: PCSK9 inhibitors reduce plasma lipoprotein(a) concentrations but a mechanistic understanding remains elusive. Evaluation of evolocumab for use in patients without prior myocardial infarction or stroke is underway (NCT03872401). Concerns regarding the cost-effectiveness of PCSK9 inhibitors have continued to thwart access to these drugs, though innovative models of care delivery and price reductions have improved this situation. Inclisiran, a small interfering ribonucleic acid (siRNA), reduces translation of PCSK9 and demonstrates more durable reductions in low-density lipoprotein-cholesterol (LDL-C). It is currently evaluated in the context of a phase III cardiovascular outcome trial in patients with established vascular disease (NCT03705234). SUMMARY: The current scope of PCSK9 inhibitor therapy in preventive cardiology is limited to patients with familial hypercholesterolemia and/or established atherosclerotic cardiovascular disease. Future cardiovascular outcome trial results with PCSK9 blocking antibodies in primary prevention and with siRNA to PCSK9 in secondary prevention, improved understanding of the drivers of lipoprotein(a) reduction with PCSK9 inhibition, and cost-effectiveness will determine the future role of this therapeutic class.

RESUMO

PURPOSE OF REVIEW: Hypercholesterolemia and statin treatment are nowadays common among people older than 75 years, but clinical heterogeneity in this increasing age group is wide, and treatment decisions may differ from those in younger patients. Aim is to discuss the presentation, modifying factors, and treatment decisions of hypercholesterolemia (usually with statins) in older persons and focusing on primary prevention. RECENT FINDINGS: There are no randomized controlled trials in persons older than 80 years at baseline. Randomized controlled trial findings in younger patients and 75+ subgroups and in observational studies support treatment in secondary prevention of atherosclerotic cardiovascular disease (ASCVD), but trial evidence in primary prevention is less clear. Available data do not imply specific harms in older patients, and, therefore, also, judicious primary prevention is possible. However, persons older than 75 years are biologically a very heterogeneous group with frequent frailty, comorbid conditions, and multiple concomitant drugs. All these, as well as personal preferences, must be taken into account in treatment decisions. Statin treatment is only one way to prevent ASCVD in older people. Treatment of hypercholesterolemia should be started far before 75-80 years, and there is no need to discontinue statin treatment due to chronological age alone. After 75 years, treatment should be started in patients with ASCVD and judiciously in primary prevention. Like all prevention, statin treatment should be discontinued when palliative treatment is started. Ongoing and planned trials in 70+ individuals will give more information about primary prevention in older persons.

RESUMO

BACKGROUND: In patients with acute coronary syndrome (ACS), alirocumab reduced the risk of recurring ischemic events. ODYSSEY J-IVUS assessed the effect of alirocumab on coronary atheroma volume in Japanese patients recently hospitalized with ACS and hypercholesterolemia, using intravascular ultrasound imaging analysis.Methods and Results:Patients (n=206) who at index ACS diagnosis either had low-density lipoprotein cholesterol (LDL-C) ≥2.59 mmol/L (≥100 mg/dL) despite stable statin therapy, or were not on statins with LDL-C levels above target after statin initiation, were randomized (1:1) to alirocumab (75 mg every 2 weeks [Q2 W]/up to 150 mg Q2 W), or standard of care (SoC; atorvastatin ≥10 mg/day or rosuvastatin ≥5 mg/day) for 36 weeks. The primary efficacy endpoint (week [W] 36 mean [standard error] percent change in normalized total atheroma volume [TAV] from baseline) was -3.1 (1.0)% with SoC vs. -4.8 (1.0)% with alirocumab (between-group difference: -1.6 [1.4]; P=0.23). W36 absolute change from baseline in percent atheroma volume was -1.3 (0.4)% (SoC) and -1.4 (0.4)% (alirocumab; nominal P=0.79). At W36, LDL-C was reduced from baseline by 13.4% (SoC) vs. 63.9% (alirocumab; nominal P<0.0001). In total, 61.8% (SoC) and 75.7% (alirocumab) of patients reported treatment-emergency adverse events. CONCLUSIONS: In Japanese patients with ACS and hypercholesterolemia inadequately controlled despite statin therapy, from baseline to W36, a numerically greater percent reduction in normalized TAV was observed with alirocumab vs. SoC, which did not reach statistical significance.
