Treat-to-Target or High-Intensity Statin in Patients With Coronary Artery Disease: A Randomized Clinical Trial

Methodological quality and clinical recommendations of guidelines on the management of dyslipidaemias for cardiovascular disease risk reduction: a systematic review and an appraisal through AGREE II and AGREE REX tools

BACKGROUND

Clinical practice guidelines (CPGs) are statements to assist practitioners and stakeholders in decisions about healthcare. Low methodological quality guidelines may prejudice decision-making and negatively affect clinical outcomes in non-communicable diseases, such as cardiovascular diseases worsted by poor lipid management. We appraised the quality of CPGs on dyslipidemia management and synthesized the most updated pharmacological recommendations.

METHODS

A systematic review following international recommendations was performed. Searches to retrieve CPG on pharmacological treatments in adults with dyslipidaemia were conducted in PubMed, Scopus, and Trip databases. Eligible articles were assessed using AGREE II (methodological quality) and AGREE-REX (recommendation excellence) tools. Descriptive statistics were used to summarize data. The most updated guidelines (published after 2019) had their recommendations qualitatively synthesized in an exploratory analysis.

RESULTS

Overall, 66 guidelines authored by professional societies (75%) and targeting clinicians as primary users were selected. The AGREE II domains Scope and Purpose (89%) and Clarity of Presentation (97%), and the AGREE-REX item Clinical Applicability (77.0%) obtained the highest values. Conversely, guidelines were methodologically poorly performed/documented (46%) and scarcely provided data on the implementability of practical recommendations (38%). Recommendations on pharmacological treatments are overall similar, with slight differences concerning the use of supplements and the availability of drugs.

CONCLUSION

High-quality dyslipidaemia CPG, especially outside North America and Europe, and strictly addressing evidence synthesis, appraisal, and recommendations are needed, especially to guide primary care decisions. CPG developers should consider stakeholders' values and preferences and adapt existing statements to individual populations and healthcare systems to ensure successful implementation interventions.

A drug mix and dose decision algorithm for individualized type 2 diabetes management

Pharmacotherapy guidelines for type 2 diabetes (T2D) emphasize patient-centered care, but applying this approach effectively in outpatient practice remains challenging. Data-driven treatment optimization approaches could enhance individualized T2D management, but current approaches cannot account for drug-specific and dose-dependent variations in safety and efficacy. We developed and evaluated an AI Drug mix and dose Advisor (AIDA) for glycemic management, using electronic medical records from 107,854 T2D patients in the SingHealth Diabetes Registry. Given a patient's medical profile, AIDA leverages a predict-then-optimize approach to identify the minimal drug mix and dose changes required to optimize glycemic control, subject to clinical knowledge-based guidelines. On unseen data from large internal, external, and temporal validation sets, AIDA recommendations were estimated to improve post-visit glycated hemoglobin (HbA1c) by an average of 0.40-0.68% over standard of care (P < 0.0001). In qualitative evaluations on 60 diverse cases by a panel of three endocrinologists, AIDA recommendations were mostly rated as reasonable and precise. Finally, AIDA's ability to account for drug-dose specifics offered several advantages over competing methods, including greater consistency with practice preferences and clinical guidelines for practical but effective options, indication-based treatments, and renal dosing. As AIDA provides drug-dose recommendations to improve outcomes for individual T2D patients, it could be used for clinical decision support at point-of-care, especially in resource-limited settings.

Medication-Induced Hyperglycemia and Diabetes Mellitus: A Review of Current Literature and Practical Management Strategies

With the increasing global incidence of diabetes mellitus, physicians may encounter more patients with acute and chronic complications of medication-induced hyperglycemia and diabetes. Moreover, medication-induced diabetes may be an important contributing factor to the high rates of diabetes, and recognizing its impact and risk is a critical step in curtailing its effect on the global population. It has long been recognized that multiple classes of medications are associated with hyperglycemia through various mechanisms, and the ability to foresee this and implement adequate management strategies are important. Moreover, different antihyperglycemic medications are better suited to combat the hyperglycemia encountered with different classes of medications, so it is critical that physicians can recognize which agents should be used, and which medications to avoid in certain types of medication-induced hyperglycemia. In this review, we will discuss the evidence behind the main classes of medications that cause hyperglycemia, their mechanism of action, specific agents that are associated with worsened glycemic control, and, most importantly, management strategies that are tailored to each specific class.

Effect of rosuvastatin versus atorvastatin on new-onset diabetes mellitus in patients treated with high-intensity statin therapy for coronary artery disease: a post-hoc analysis from the LODESTAR randomized clinical trial

BACKGROUND

The impact of rosuvastatin versus atorvastatin on new-onset diabetes mellitus (NODM) among patients treated with high-intensity statin therapy for coronary artery disease (CAD) remains to be clarified. This study aimed to evaluate the risk of NODM in patients with CAD treated with rosuvastatin compared to atorvastatin in the randomized LODESTAR trial.

METHODS

In the LODESTAR trial, patients with CAD were randomly assigned to receive either rosuvastatin or atorvastatin using a 2-by-2 factorial randomization. In this post-hoc analysis, the 3-year incidence of NODM was compared between rosuvastatin and atorvastatin treatment in the as-treated population with high-intensity statin therapy as the principal population of interest.

RESULTS

Among 2932 patients without diabetes mellitus at baseline, 2377 were included in the as-treated population analysis. In the as-treated population with high-intensity statin therapy, the incidence of NODM was not significantly different between the rosuvastatin and atorvastatin groups (11.4% [106/948] versus 8.8% [73/856], hazard ratio [HR] = 1.32, 95% confidence interval [CI] = 0.98 to 1.77, P = 0.071). When the risk of NODM with rosuvastatin versus atorvastatin was assessed according to the achieved low-density lipoprotein cholesterol (LDL-C) level, the risk of NODM began to increase at a LDL-C level below 70 mg/dL. The incidence of NODM was significantly greater in the rosuvastatin group than it was in the atorvastatin group when the achieved LDL-C level was < 70 mg/dL (13.9% versus 8.0%; HR = 1.79, 95% CI 1.18 to 2.73, P = 0.007).

CONCLUSIONS

Among CAD patients receiving high-intensity statin therapy, the incidence of NODM was not significantly different between rosuvastatin and atorvastatin. However, a drug effect of the statin type on NODM was observed when the achieved LDL-C level was < 70 mg/dL.

Treat-to-target or high-intensity statin treatment in older adults with coronary artery disease: a post hoc analysis of the LODESTAR trial

BACKGROUND

The optimal statin treatment strategy that is balanced for both efficacy and safety has not been clearly determined in older adults with coronary artery disease (CAD).

METHODS

In the post hoc analysis of the LODESTAR (low-density lipoprotein cholesterol-targeting statin therapy versus intensity-based statin therapy in patients with coronary artery disease) trial, the impact between a treat-to-target strategy versus a high-intensity statin therapy strategy was compared in older adults (aged 75 years or older). The goal of treat-to-target low-density lipoprotein cholesterol (LDL-C) level was 50-70 mg/dl. The primary endpoint comprised the three-year composite of all-cause death, myocardial infarction, stroke or coronary revascularisation.

RESULTS

Among 4,400 patients with CAD enrolled in the LODESTAR trial, 822 (18.7%) were aged 75 years or older. Poor clinical outcomes and risk factors for atherosclerosis were more frequently observed in older adults than in younger population (<75 years old). Among these older adults with CAD, the prescription rate of high-intensity statin was significantly lower in the treat-to-target strategy group throughout the study period (P < 0.001). The mean LDL-C level for three years was 65 ± 16 mg/dl in the treat-to-target strategy group and 64 ± 18 mg/dl in the high-intensity statin group (P = 0.34). The incidence of primary endpoint occurrence was 10.9% in the treat-to-target strategy group and 12.0% in the high-intensity statin group (hazard ratio 0.92, 95% confidence interval 0.61-1.38, P = 0.69).

CONCLUSIONS

High-intensity statin therapy is theoretically more necessary in older adults because of worse clinical outcomes and greater number of risk factors for atherosclerosis. However, the primary endpoint occurrence with a treat-to-target strategy with an LDL-C goal of 50-70 mg/dl was comparable to that of high-intensity statin therapy and reduced utilisation of a high-intensity statin. Taking efficacy as well as safety into account, adopting a tailored approach may be considered for this high-risk population.

Research trends in lipid-lowering therapies for coronary heart disease combined with hyperlipidemia: a bibliometric study and visual analysis

Background

Cardiovascular disease (CVD) poses a significant global health and economic challenge, with atherosclerosis being a primary cause. Over the past 40 years, substantial research has been conducted into the prevention and reversal of atherosclerosis, resulting in the development of lipid-lowering agents such as statins and fibrates. Despite the extensive literature and formulation of numerous therapeutic guidelines in this domain, a comprehensive bibliometric analysis of the current research landscape and trends has not been performed. This study aimed to elucidate the evolution and milestones of research into lipid-lowering treatments for coronary heart disease (CHD) in conjunction with hyperlipidemia through bibliometric analysis, offering insights into future directions for treatment strategies.

Methods

This study examined publications from 1986 to 2023 retrieved from the Web of Science database (Core Collection). Utilizing tools such as VOSviewer, Pajek, and CiteSpace, we analyzed publication and citation numbers, H-indexes, contributions by countries and institutions, authorship, journal sources, and keyword usage to uncover research trajectories and areas of focus.

Results

Our analysis of 587 publications revealed a recent surge in research output, particularly post-2003. The American Journal of Cardiology published the highest number of studies, with 40 articles, whereas Circulation received the highest number of citations (6,266). Key contributors included the United States, Japan, and China, with the United States leading in citation numbers and the H-index. Harvard University and Leiden University emerged as pivotal institutions, and Professors J. Wouter Jukema and Robert P. Giugliano were identified as leading experts. Keyword analysis disclosed five thematic clusters, indicating a shift in research towards new drug combinations and strategies, signaling future research directions.

Conclusion

The last 4 decades have seen a notable rise in publications on lipid-lowering therapies for CHD and hyperlipidemia, with the United States retaining world-leading status. The increase in international collaboration aids the shift towards research into innovative lipid-lowering agents and therapeutic approaches. PCSK9 inhibitors and innovative combination therapies, including antisense oligonucleotides and angiopoietin-like protein 3 inhibitors, provide avenues for future research, intending to maximize the safety and efficacy of treatment approaches.

Synergistic Effect of Layered Double Hydroxides Nanodosage Form to Induce Apoptosis and Ferroptosis in Breast Cancer

Background

Breast cancer is the most common cancer in women and one of the leading causes of cancer death worldwide. Ferroptosis, a promising mechanism of killing cancer cells, has become a research hotspot in cancer therapy. Simvastatin (SIM), as a potential new anti-breast cancer drug, has been shown to cause ferroptosis of cancer cells and inhibit breast cancer metastasis and recurrence. The purpose of this study is to develop a novel strategy boosting ferroptotic cascade for synergistic cancer therapy.

Methods

In this paper, iron base form of layered double hydroxide supported simvastatin (LDHs-SIM) was synthesized by hydrothermal co-precipitation method. The characterization of LDHs-SIM were assessed by various analytical techniques, including ultraviolet-visible (UV-vis) spectroscopy, X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and transmission electron microscopy (TEM). Biological activity, ferroptosis mechanism and biocompatibility were analyzed through in vivo and in vitro analysis, so as to evaluate its therapeutic effect on breast cancer.

Results

The constructed LDHs-SIM nanosystem can not only release SIM through mevalonate (MVA) pathway, inhibit the expression of glutathione peroxidase 4 (GPX4), inhibit the expression of SLC7A11 and reduce the synthesis efficiency of GSH, but also promote the accumulation of Fe2+ in cells through the release of Fe3+, and increase the intracellular ROS content. In addition, LDHs-SIM nanosystem can induce apoptosis of breast cancer cells to a certain extent, and achieve the synergistic effect of apoptosis and ferroptosis.

Conclusion

In the present study, we demonstrated that nanoparticles of layered double hydroxides (LDHs) loaded with simvastatin were more effective than a free drug at inhibiting breast cancer cell growth, In addition, superior anticancer therapeutic effects were achieved with little systemic toxicity, indicating that LDHs-SIM could serve as a safe and high-performance platform for ferroptosis-apoptosis combined anticancer therapy.

New pharmacological agents and novel cardiovascular pharmacotherapy strategies in 2023

Although cardiovascular diseases (CVDs) are the leading cause of death worldwide, their pharmacotherapy remains suboptimal. Thus, there is a clear unmet need to develop more effective and safer pharmacological strategies. In this review, we summarize the most relevant advances in cardiovascular pharmacology in 2023, including the approval of first-in-class drugs that open new avenues for the treatment of atherosclerotic CVD and heart failure (HF). The new indications of drugs already marketed (repurposing) for the treatment of obstructive hypertrophic cardiomyopathy, hypercholesterolaemia, type 2 diabetes, obesity, and HF; the impact of polypharmacy on guideline-directed drug use is highlighted as well as results from negative clinical trials. Finally, we end with a summary of the most important phase 2 and 3 clinical trials assessing the efficacy and safety of cardiovascular drugs under development for the prevention and treatment of CVDs.

Advances in Gut Microbiota-Targeted Therapeutics for Metabolic Syndrome

Previous investigations have illuminated the significant association between the gut microbiome and a broad spectrum of health conditions, including obesity, diabetes, cardiovascular diseases, and psychiatric disorders. Evidence from certain studies suggests that dysbiosis of the gut microbiota may play a role in the etiology of obesity and diabetes. Moreover, it is acknowledged that dietary habits, pharmacological interventions, psychological stress, and other exogenous factors can substantially influence the gut microbial composition. For instance, a diet rich in fiber has been demonstrated to increase the population of beneficial bacteria, whereas the consumption of antibiotics can reduce these advantageous microbial communities. In light of the established correlation between the gut microbiome and various pathologies, strategically altering the gut microbial profile represents an emerging therapeutic approach. This can be accomplished through the administration of probiotics or prebiotics, which aim to refine the gut microbiota and, consequently, mitigate the manifestations of associated diseases. The present manuscript evaluates the recent literature on the relationship between gut microbiota and metabolic syndrome published over the past three years and anticipates future directions in this evolving field.

Macrophage fatty acid oxidation in atherosclerosis

Atherosclerosis significantly contributes to the development of cardiovascular diseases (CVD) and is characterized by lipid retention and inflammation within the artery wall. Multiple immune cell types are implicated in the pathogenesis of atherosclerosis, macrophages play a central role as the primary source of inflammatory effectors in this pathogenic process. The metabolic influences of lipids on macrophage function and fatty acid β-oxidation (FAO) have similarly drawn attention due to its relevance as an immunometabolic hub. This review discusses recent findings regarding the impact of mitochondrial-dependent FAO in the phenotype and function of macrophages, as well as transcriptional regulation of FAO within macrophages. Finally, the therapeutic strategy of macrophage FAO in atherosclerosis is highlighted.

Eliminating Health Disparities in Atrial Fibrillation, Heart Failure, and Dyslipidemia: A Path Toward Achieving Pharmacoequity

PURPOSE OF REVIEW

Pharmacoequity refers to the goal of ensuring that all patients have access to high-quality medications, regardless of their race, ethnicity, gender, or other characteristics. The goal of this article is to review current evidence on disparities in access to cardiovascular drug therapies across sociodemographic subgroups, with a focus on heart failure, atrial fibrillation, and dyslipidemia.

RECENT FINDINGS

Considerable and consistent disparities to life-prolonging heart failure, atrial fibrillation, and dyslipidemia medications exist in clinical trial representation, access to specialist care, prescription of guideline-based therapy, drug affordability, and pharmacy accessibility across racial, ethnic, gender, and other sociodemographic subgroups. Researchers, health systems, and policy makers can take steps to improve pharmacoequity by diversifying clinical trial enrollment, increasing access to inpatient and outpatient cardiology care, nudging clinicians to increase prescription of guideline-directed medical therapy, and pursuing system-level reforms to improve drug access and affordability.

Lipoproteins, Cholesterol, and Atherosclerotic Cardiovascular Disease in East Asians and Europeans

One fifth of the world population live in East Asia comprising Japan, Korea, and China where ischemic heart disease, a major component of atherosclerotic cardiovascular disease (ASCVD), is the second most frequent cause of death. Each of low-density lipoproteins (LDL), remnant lipoproteins, and lipoprotein(a), summarized as non-high-density lipoproteins (non-HDL) or apolipoprotein B (apoB) containing lipoproteins, causes ASCVD. However, a significant proportion of the evidence on lipoproteins and lipoprotein cholesterol with risk of ASCVD came from White people mainly living in Europe and North America and not from people living in East Asia or of East Asian descent. With a unique biological, geohistorical, and social background in this world region, East Asians have distinctive characteristics that might have potential impact on the association of lipoproteins and lipoprotein cholesterol with risk of ASCVD. Considering the movement across national borders in the World, understanding of lipoprotein and lipoprotein cholesterol evidence on ASCVD in East Asia is important for both East Asian and non-East Asian populations wherever they live in the World.In this review, we introduce the biological features of lipoproteins and lipoprotein cholesterol and the evidence for their association with risk of ASCVD in East Asian and European populations. We also provide an overview of guideline recommendations for prevention of ASCVD in these two different world regions. Finally, specific preventive strategies and future perspectives are touched upon.

Rosuvastatin versus atorvastatin treatment in adults with coronary artery disease: secondary analysis of the randomised LODESTAR trial

OBJECTIVE

To compare the long term efficacy and safety of rosuvastatin with atorvastatin treatment in adults with coronary artery disease.

DESIGN

Randomised, open label, multicentre trial.

SETTING

12 hospitals in South Korea, September 2016 to November 2019.

PARTICIPANTS

4400 adults (age ≥19 years) with coronary artery disease.

INTERVENTIONS

Participants were assigned to receive either rosuvastatin (n=2204) or atorvastatin (n=2196) using 2×2 factorial randomisation.

MAIN OUTCOME MEASURES

The primary outcome was a three year composite of all cause death, myocardial infarction, stroke, or any coronary revascularisation. Secondary outcomes were safety endpoints: new onset diabetes mellitus; hospital admissions due to heart failure; deep vein thrombosis or pulmonary thromboembolism; endovascular revascularisation for peripheral artery disease; aortic intervention or surgery; end stage kidney disease; discontinuation of study drugs owing to intolerance; cataract surgery; and a composite of laboratory detected abnormalities.

RESULTS

4341 of the 4400 participants (98.7%) completed the trial. Mean daily dose of study drugs was 17.1 mg (standard deviation (SD) 5.2 mg) in the rosuvastatin group and 36.0 (12.8) mg in the atorvastatin group at three years (P<0.001). The primary outcome occurred in 189 participants (8.7%) in the rosuvastatin group and 178 (8.2%) in the atorvastatin group (hazard ratio 1.06, 95% confidence interval 0.86 to 1.30; P=0.58). The mean low density lipoprotein (LDL) cholesterol level during treatment was 1.8 mmol/L (SD 0.5 mmol/L) in the rosuvastatin group and 1.9 (0.5) mmol/L in the atorvastatin group (P<0.001). The rosuvastatin group had a higher incidence of new onset diabetes mellitus requiring initiation of antidiabetics (7.2% v 5.3%; hazard ratio 1.39, 95% confidence interval 1.03 to 1.87; P=0.03) and cataract surgery (2.5% v 1.5%; 1.66, 1.07 to 2.58; P=0.02). Other safety endpoints did not differ between the two groups.

CONCLUSIONS

In adults with coronary artery disease, rosuvastatin and atorvastatin showed comparable efficacy for the composite outcome of all cause death, myocardial infarction, stroke, or any coronary revascularisation at three years. Rosuvastatin was associated with lower LDL cholesterol levels but a higher risk of new onset diabetes mellitus requiring antidiabetics and cataract surgery compared with atorvastatin.

Beyond statins: New pharmacological targets to decrease LDL-cholesterol and cardiovascular events

The pharmacological treatment of dyslipidemia, a major modifiable risk factor for developing atherosclerotic cardiovascular disease (ASCVD), remains a debated and controversial issue, not only in terms of the most appropriate therapeutic range for lipid levels, but also with regard to the optimal strategy and sequence approach (stepwise vs upstream therapy). Current treatment guidelines for the management of dyslipidemia focus on the intensity of low-density lipoprotein cholesterol (LDL-C) reduction, stratified according to risk for developing ASCVD. Beyond statins and ezetimibe, different medications targeting LDL-C have been recently approved by regulatory agencies with potential innovative mechanisms of action, including proprotein convertase subtilisin/kexin type 9 modulators (monoclonal antibodies such as evolocumab and alirocumab; small interfering RNA molecules such as inclisiran), ATP-citrate lyase inhibitors (bempedoic acid), angiopoietin-like 3 inhibitors (evinacumab), and microsomal triglyceride transfer protein inhibitors (lomitapide). An understanding of their pharmacological aspects, benefit-risk profile, including impact on hard cardiovascular endpoints beyond LDL-C reduction, and potential advantages from the patient perspective (e.g., adherence) - the focus of this evidence-based review - is crucial for practitioners across medical specialties to minimize therapeutic inertia and support clinical practice.

PEER simplified lipid guideline 2023 update: Prevention and management of cardiovascular disease in primary care

OBJECTIVE

To update the 2015 clinical practice guideline and provide a simplified approach to lipid management in the prevention of cardiovascular disease (CVD) for primary care.

METHODS

Following the Institute of Medicine's Clinical Practice Guidelines We Can Trust, a multidisciplinary, pan-Canadian guideline panel was formed. This panel was represented by primary care providers, free from conflicts of interest with industry, and included the patient perspective. A separate scientific evidence team performed evidence reviews on statins, ezetimibe, proprotein convertase subtilisin-kexin type 9 inhibitors, fibrates, bile acid sequestrants, niacin, and omega-3 supplements (docosahexaenoic acid with eicosapentaenoic acid [EPA] or EPA ethyl ester alone [icosapent]), as well as on 11 supplemental questions. Recommendations were finalized by the guideline panel through use of the Grading of Recommendations Assessment, Development and Evaluation methodology.

RECOMMENDATIONS

All recommendations are presented in a patient-centred manner designed with the needs of family physicians and other primary care providers in mind. Many recommendations are similar to those published in 2015. Statins remain first-line therapy for both primary and secondary CVD prevention, and the Mediterranean diet and physical activity are recommended to reduce cardiovascular risk (primary and secondary prevention). The guideline panel recommended against using lipoprotein a, apolipoprotein B, or coronary artery calcium levels when assessing cardiovascular risk, and recommended against targeting specific lipid levels. The team also reviewed new evidence pertaining to omega-3 fatty acids (including EPA ethyl ester [icosapent]) and proprotein convertase subtilisin-kexin type 9 inhibitors, and outlined when to engage in informed shared decision making with patients on interventions to lower cardiovascular risk.

CONCLUSION

These updated evidence-based guidelines provide a simplified approach to lipid management for the prevention and management of CVD. These guidelines were created by and for primary health care professionals and their patients.

Treat-to-target versus high-intensity statin treatment in patients with or without diabetes mellitus: a pre-specified analysis from the LODESTAR trial

Background

The impact of titrated versus fixed intensity statin therapy in patients with coronary artery disease (CAD) and diabetes mellitus (DM) remains to be elucidated.

Methods

This was a pre-specified analysis of patients with and without DM from the LODESTAR trial. Patients with CAD were randomly assigned to receive either a treat-to-target strategy with a target LDL-C level of 50-70 mg/dL or a high-intensity statin treatment. Primary outcome was the 3-year composite of all-cause death, myocardial infarction, stroke, or coronary revascularization. Secondary outcomes were safety endpoints. This trial is registered with ClinicalTrials.gov, NCT02579499.

Findings

Between September 9, 2016 and November 27, 2019, 4400 patients with CAD were enrolled in the LODESTAR trial. The median age was 65 years (interquartile range, 59-73 years), 3172 (72%) were male, and 1468 (33%) had DM at baseline. There was no significant difference in the occurrence of the primary outcome between the treat-to-target group and high-intensity statin group among patients with DM (10.5% versus 11.1%, hazard ratio [HR] 0.94, 95% confidence interval [CI] 0.69-1.29, p = 0.70) and those without DM (6.9% versus 7.5%, HR 0.93, 95% CI 0.71-1.21, p = 0.58). Among patients without DM, there was a trend towards a lower risk of new-onset DM in the treat-to-target group (8.4% versus 10.4% in the high-intensity statin group, HR 0.79, 95% CI 0.62-1.01; p = 0.06).

Interpretation

In patients with CAD, a treat-to-target LDL-C strategy of 50-70 mg/dL as the goal was comparable to high-intensity statin therapy in terms of 3-year clinical efficacy and safety outcomes regardless of the presence of DM.

Lignes directrices simplifiées de PEER sur les lipides : actualisation 2023

Objectif

Actualiser le guide de pratique clinique de 2015 et présenter une approche simplifiée de la prise en charge des lipides dans la prévention des maladies cardiovasculaires (MCV) en première ligne.

Méthodes

Conformément aux recommandations de l’Institute of Medicine dans Clinical Practice Guidelines We Can Trust , un panel pancanadien d’experts multidisciplinaires en lignes directrices a été formé. Ce panel était représentatif des cliniciens en soins primaires, libre de tout conflit d’intérêts avec l’industrie, et il tenait compte des points de vue des patients. Une équipe distincte, responsable des données probantes scientifiques, a passé en revue l’information sur les statines, l’ézétimibe, les inhibiteurs de la proprotéine convertase subtilisine-kexine de type 9, les fibrates, les chélateurs des acides biliaires, la niacine et les suppléments d’omega-3 (acide docosahexaénoïque avec acide eicosapentaénoïque [EPA] ou ester éthylique de l’EPA seul [icosapent]), ainsi que sur la réponse à 11 questions supplémentaires. Le panel des lignes directrices a finalisé les recommandations en utilisant la méthodologie GRADE (Grading of Recommendations Assessment, Development and Evaluation).

Recommandations

Toutes les recommandations sont présentées de manière à être centrées sur le patient et conçues en ayant à l’esprit les besoins des médecins de famille et des autres cliniciens des soins primaires. De nombreuses recommandations sont semblables à celles publiées en 2015. Les statines demeurent le traitement de première intention pour la prévention tant primaire que secondaire des MCV, et le régime méditerranéen et l’activité physique sont recommandés pour réduire le risque cardiovasculaire (en prévention primaire et secondaire). Le panel des lignes directrices a recommandé de ne pas utiliser le dosage des lipoprotéines a, des apolipoprotéines B ou le score calcique coronarien (SCC) dans l’évaluation du risque cardiovasculaire, et de ne pas cibler de seuils précis de taux lipidiques. L’équipe a aussi passé en revue de nouvelles données concernant les acides gras omega-3 (y compris l’ester éthylique d’EAP [icosapent]) et les inhibiteurs de la proprotéine convertase subtilisine-kexine de type 9, et a précisé les moments où il convient de procéder à une prise de décision partagée avec les patients sur les interventions pour diminuer le risque cardiovasculaire.

Conclusion

Ces lignes directrices actualisées et fondées sur des données probantes présentent une approche simplifiée de la prise en charge des lipides pour la prévention et le traitement des MCV. Ce guide de pratique clinique a été conçu par et pour des professionnels de la santé en soins primaires et leurs patients.
