Ezetimibe Added to Statin Therapy after Acute Coronary Syndromes

Changes in bile acid composition are correlated with reduced intestinal cholesterol uptake in intestine-specific WASH-deficient mice

The Wiskott-Aldrich syndrome protein and SCAR homolog (WASH) complex is a pentameric protein complex localized at endosomes, where it facilitates the transport of numerous receptors from endosomes toward the plasma membrane. Recent studies have shown that the WASH complex plays an essential role in cholesterol and glucose homeostasis in humans and mice. To investigate the physiological importance of intestinal WASH, we ablated the WASH component WASHC1 specifically in murine enterocytes. Male and female intestine-specific WASHC1-deficient mice (Washc1IKO) were challenged with either a standard chow diet or a high-cholesterol (1.25 %) diet (HCD). Washc1IKO mice fed a standard diet did not present any apparent phenotype, but when fed an HCD, their hepatic cholesterol levels were ~ 50 % lower compared to those observed in control mice. The intestinal cholesterol absorption was almost 2-fold decreased in Washc1IKO mice, which translated into increased fecal neutral sterol loss. The intestinal expression of cholesterogenic genes, such as Hmgcs1, Hmgcr, and Ldlr, was significantly higher in Washc1IKO mice than in control mice and correlated with increased whole-body de novo cholesterol synthesis, likely to compensate for impaired intestinal cholesterol absorption. Unexpectedly, the ratio of biliary 12α-/non-12α-hydroxylated bile acids (BAs) was decreased in Washc1IKO mice and reversing this reduced ratio by feeding the mice with the HCD supplemented with 0.5 % (w/w) sodium cholate normalized the improvement of hepatic cholesterol levels in Washc1IKO mice. Our data indicate that the intestinal WASH complex plays an important role in intestinal cholesterol absorption, likely by modulating biliary BA composition.

Moderate-intensity statin with ezetimibe combination therapy versus high-intensity statin monotherapy in patients with metabolic syndrome and atherosclerotic cardiovascular disease: A post-hoc analysis of the RACING trial

AIM

This study evaluated the safety and efficacy of a moderate-intensity statin with ezetimibe combination therapy versus high-intensity statin monotherapy in patients with metabolic syndrome (MetS) and atherosclerotic cardiovascular disease.

MATERIALS AND METHODS

In this post-hoc subgroup analysis of the RACING trial, patients were analysed based on the presence of MetS. MetS was defined as meeting at least three of the five following criteria: (a) elevated waist circumference; (b) elevated triglycerides; (c) reduced high-density lipoprotein cholesterol; (d) elevated blood pressure; and (e) elevated fasting glucose. The primary outcome was a 3-year composite of cardiovascular death, major cardiovascular events, or non-fatal stroke.

RESULTS

Of the 3780 patients enrolled in the RACING trial, 1703 (45.1%) had MetS at baseline. The primary outcome rate was 10.1% and 10.3% in patients with MetS receiving ezetimibe combination therapy versus high-intensity statin monotherapy (hazard ratio = 0.97; 95% confidence interval = 0.72-1.32; p = .868). Lower rates of intolerance-related drug discontinuation or dose reduction (3.9% vs. 8.0%; p < .001) and lower low-density lipoprotein cholesterol levels (57 vs. 65 mg/dl; p < .001) were observed with ezetimibe combination therapy versus high-intensity statin monotherapy. Furthermore, the rate of new-onset diabetes was 18.5% and 19.1% in each group (p = .822). There were no significant interactions between MetS and therapy regarding study outcomes in the total population.

CONCLUSIONS

In patients with MetS and atherosclerotic cardiovascular disease, a moderate-intensity statin with ezetimibe combination therapy had comparable cardiovascular benefits with those of high-intensity statin monotherapy. Meanwhile, ezetimibe combination therapy was associated with lower drug intolerance and low-density lipoprotein cholesterol levels, but there was no apparent between-group difference in new-onset diabetes.

Evinacumab-dgnb (Evkeeza-REGN1500), A Novel Lipid-Lowering Therapy for Homozygous Familial Hypercholesterolemia

Chronically elevated low-density lipoprotein (LDL) has harmful effects on the vasculature including increased vasoconstriction and the formation of plaques which may rupture, causing coronary heart disease and stroke. In patients with familial hypercholesterolemia, adequate reduction of LDL is especially challenging. Although HMG-CoA reductase inhibitors (statins) are the mainstays for LDL lowering, other treatments such as proprotein convertase subtilisin/kexin type 9 inhibitors, bempedoic acid, incliseran, lomitapide, and apheresis have been employed in an effort to achieve adequate LDL reduction in these patients. Despite these available therapies, many patients with familial hypercholesterolemia do not meet the LDL targets suggested in current guidelines. Evinacumab is a novel lipid-lowering therapy that exerts its LDL-lowering effect through inhibition of angiopoietin-like protein 3 (ANGPTL3). ANGPTL3 inhibits the breakdown of triglyceride-rich lipoproteins, such as very low-density lipoprotein and chylomicrons. By inhibiting ANGPTL3, evinacumab allows these lipoproteins to be degraded, ultimately leading to reductions in LDL, high-density lipoprotein, and triglycerides. Clinical trials have demonstrated evinacumab to be safe and effective in reducing LDL. However, data are lacking regarding its potential to reduce risk of atherosclerotic cardiovascular disease. Evinacumab is generally well tolerated with the primary adverse effects comprising infusion reactions, nasopharyngitis, influenza-like illness, dizziness, rhinorrhea, and nausea. While evinacumab is an interesting therapy, until it is proven to reduce cardiovascular events, its high cost leaves its anticipated role in therapy somewhat ambiguous. In the meantime, it may be a useful therapy for those with homozygous familial hypercholesterolemia.

Executive summary of the Hellenic Atherosclerosis Society guidelines for the diagnosis and treatment of dyslipidemias - 2023

Atherosclerotic cardiovascular disease (ASCVD) remains the main cause of death worldwide, and thus its prevention, early diagnosis and treatment is of paramount importance. Dyslipidemia represents a major ASCVD risk factor that should be adequately managed at different clinical settings. 2023 guidelines of the Hellenic Atherosclerosis Society focus on the assessment of ASCVD risk, laboratory evaluation of dyslipidemias, new and emerging lipid-lowering drugs, as well as diagnosis and treatment of lipid disorders in women, the elderly and in patients with familial hypercholesterolemia, acute coronary syndromes, heart failure, stroke, chronic kidney disease, diabetes, autoimmune diseases, and non-alcoholic fatty liver disease. Statin intolerance is also discussed.

Lipid clinical trials with special reference to Indian population

Indians have a pattern of atherogenic dyslipidaemia characterised by not so high LDL-C but elevated small, dense LDL-C, elevated triglyceride levels and low HDL-C levels. In addition, different lipid-lowering drugs exhibit pharmacokinetic variability in Indians, which may have implications on the optimum doses required to achieve the desired LDL-C levels. Currently the management of dyslipidaemia in Indians are based on the landmark trials, which largely included western population. This review focusses on major clinical trials of lipid lowering drugs with special reference to the Indian population.

An update on inclisiran for the treatment of elevated LDL cholesterol

INTRODUCTION

The burden of atherosclerotic cardiovascular disease (ASCVD) persists globally, demanding innovative therapeutic strategies. This manuscript provides an expert opinion on the significance of managing low-density lipoprotein cholesterol in ASCVD prevention and introduces inclisiran, a novel small interfering RNA targeting proprotein convertase subtilisin/kexin type 9 (PCSK9).

AREAS COVERED

This work delves into the intricate mechanism of inclisiran, highlighting its unique approach of hepatic intracellular PCSK9 inhibition, its precision and low off-target effects risk. Pharmacodynamic and pharmacokinetic distinctions from PCSK9 monoclonal antibodies are explored, underlining inclisiran's efficiency, extended duration, and clearance. Clinical trials, including pivotal phase-III placebo-controlled studies (ORION-9, -10, -11), the open-label ORION-3 and pooled safety analysis of these trails including the open-label phase of ORION-8, as well as real-word data are discussed to provide a comprehensive evaluation of inclisiran's efficacy and safety.

EXPERT OPINION

Inclisiran stands as a first-in-class breakthrough in lipid-lowering therapies, showing potential in alleviating the global burden of ASCVD and is supported by multiple global regulatory approvals. To optimize inclisiran's utilization and comprehend its long-term effects, future directions include pediatric studies, cardiovascular outcome trials, and extended-duration investigations. Overall, inclisiran emerges as a precise and effective therapeutic option, offering significant promise for preserving cardiovascular health.

Is there a role for earlier use of combination therapy?

As the global population ages and cardiovascular risk factors rise, we can expect a continued increase in atherosclerotic disease. Low-density lipoprotein cholesterol (LDL-C) reduction is a cornerstone of cardiovascular risk reduction with strong, causal evidence indicating that the greatest benefit is derived from early and large decreases in LDL-C. Despite the adoption of statins as the backbone of lipid-therapy regimens, numerous studies and registry analyses reveal our collective inability to achieve LDL-C goals in high-risk patients. Combination therapy with ezetimibe has been shown to result in statistically significant decreases in LDL-C level, atheroma volume, and cardiovascular adverse event rates. A major barrier to implementing an upfront combination therapy approach is the perceived side effects from therapeutic agents although multiple studies show that a therapeutic patient-physician relationship could overcome this issue. Novel agents such as PCSK-9 inhibitors, bempedoic acid, and inclisiran have the potential to achieve similar outcomes although additional research is needed regarding the cost effectiveness of these approaches. Despite these hurdles, there is a role for the newer agents early in the disease course of high-risk patients such as those with markedly elevated LDL-C >190 mg/dL and FH. The implementation of upfront combination therapy, especially in high-risk patients, will decrease clinical inertia while allowing for earlier consideration of newer, effective agents to decrease cardiovascular burden.

Comparison of Effectiveness of High Dose Statin Monotherapy With Combination of Statin and Ezetimibe to Prevent Cardiovascular Events in Patients With Acute Coronary Syndrome: A Systematic Review and Meta-Analysis

This meta-analysis aimed to compare the effectiveness of high statin monotherapy and a combination of statin and ezetimibe to prevent cardiovascular outcomes in patients with acute coronary syndrome (ACS). The study was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We conducted comprehensive searches across online databases, including MEDLINE/ PubMed, EMBASE, and the Web of Science, to find the relevant articles from the databases' inception to 10 Feb 2024. Outcomes assessed in the meta-analysis included major cardiovascular events (MACE), all-cause mortality, stroke, myocardial infarction, and unplanned revascularization. Data analysis was conducted utilizing RevMan Version 5.3.1. The comparison of outcomes between the two groups involved the calculation of risk ratios (RR) accompanied by 95% confidence intervals (CI) using either a random or fixed-effect model. Five studies were included in this meta-analysis, encompassing 48,668 patients. The pooled analysis showed that the risk of all-cause mortality was higher in patients receiving high statin monotherapy. However, no significant differences in MACE, myocardial infarction, stroke, and revascularization were reported. While acknowledging the limitations, including the lack of randomized controlled trials and the dominance of one study in the analysis, these findings underscore the importance of further research to clarify the comparative effectiveness of these treatment modalities in preventing cardiovascular outcomes in ACS patients.

Efficacy and safety of combination therapy with telmisartan, rosuvastatin, and ezetimibe in patients with dyslipidemia and hypertension: A randomized, double-blind, multicenter, therapeutic confirmatory, phase III clinical trial

This study aimed to compare and evaluate the efficacy of the blood pressure (BP) control and cholesterol-lowering effects and safety of combination therapy with telmisartan, rosuvastatin, and ezetimibe versus rosuvastatin and ezetimibe double therapy or telmisartan single therapy in dyslipidemia patients with hypertension. After a wash-out/therapeutic lifestyle change period of ≥4 weeks, a total of 100 eligible patients were randomized and received one of three treatments for 8 weeks: (1) telmisartan 80 mg/rosuvastatin 20 mg/ezetimibe 10 mg (TRE), (2) rosuvastatin 20 mg/ezetimibe 10 mg (RE), or (3) telmisartan 80 mg (T). The primary endpoint was the efficacy evaluation of TRE by comparing changes in mean sitting systolic blood pressure (msSBP) and mean percentage change in low-density lipoprotein-C (LDL-C) from baseline after 8 weeks of treatment. The least square (LS) mean (SE) changes in msSBP at 8 weeks compared with baseline were -23.02 (3.04) versus -7.18 (3.09) mmHg in the TRE and RE groups, respectively (p < .0001), and -25.80 (2.74) versus -14.92 (2.65) mmHg in the TRE and T groups, respectively (p = .0005). The percentage changes in the mean (SD) LDL-C at 8 weeks compared with baseline were -54.97% (3.49%) versus -0.17% (3.23%) in the TRE and T groups, respectively (p < .0001). No serious adverse events occurred, and no statistically significant differences in the incidence of overall AEs and adverse drug reactions occurred among the three groups. TRE therapy significantly decreased msSBP and LDL-C compared to RE or T therapy with comparable safety and tolerability profiles.

Thoracic Aortic Plaque Burden and Prediction of Cardiovascular Events in Patients Undergoing 320-row Multidetector CT Coronary Angiography

AIM

Wide volume scan (WVS) coronary computed tomography angiography (CCTA) enables aortic arch visualization. This study assessed whether the thoracic aortic plaque burden (TAPB) score can predict major cardiovascular adverse events (MACE) in addition to and independently of other obstructive coronary artery disease (CAD) attributes.

METHODS

This study included patients with suspected CAD who underwent CCTA (n=455). CCTA-WVS was used to assess CAD and the prognostic capacity of TAPB scores. Data analysis included the coronary artery calcification score (CACS), CAD status and extent, and TAPB score, calculated as the sum of plaque thickness and plaque angle at five thoracic aortic segments. The primary endpoint was MACE defined as a composite event comprised of ischemic stroke, acute coronary syndrome, and cardiovascular death.

RESULTS

During a mean follow-up period of 2.8±0.9 years, 40 of 455 (8.8%) patients experienced MACE. In the Cox proportional hazards model adjusted for clinical risks (Suita cardiovascular disease risk score), we identified TAPB score (T3) as a predictor of MACE independent of CACS ＞400 (hazards ratio [HR], 2.91; 95% confidence interval [CI], 1.26-6.72; p=0.012) or obstructive CAD (HR, 2.83; 95% CI, 1.30-6.18; p=0.009). The area under the curve for predicting MACE improved from 0.75 to 0.795 (p value=0.008) when TAPB score was added to CACS ＞400 and obstructive CAD.

CONCLUSIONS

We found that comprehensive non-invasive evaluation of TAPB and CAD has prognostic value in MACE risk stratification for suspected CAD patients undergoing CCTA.

Associations of remnant cholesterol with cardiovascular and cancer mortality in a nationwide cohort

The health significance of triglyceride-rich lipoproteins, also known as remnant cholesterol, has been increasingly recognized. However, evidence of their associations with cause-specific mortality in the general population was previously insufficient. To explore these associations and their heterogeneities across subgroups, a prospective cohort study was conducted including 3,403,414 community-based participants from ChinaHEART, an ongoing government-funded public health program throughout China, from November 2014 through December 2022. The study assessed mortality risk of all-cause mortality, cardiovascular disease (CVD) mortality (including mortality from ischemic heart diseases (IHD), ischemic stroke (IS), and hemorrhagic stroke (HS), separately), and cancer mortality (including lung cancer, stomach cancer, and liver cancer, separately). During the 4-year follow-up, 23,646 individuals died from CVD (including 8807 from IHD, 3067 from IS, and 5190 from HS), and 20,318 from cancer (including 6208 from lung cancer, 3013 from liver cancer, and 2174 from stomach cancer). Compared with individuals with remnant cholesterol <17.9 mg/dL, multivariable-adjusted mortality hazard ratios (HRs) for individuals with remnant cholesterol ≥27.7 mg/dL were 1.03 (1.00-1.05) for all-cause mortality, 1.17 (1.12-1.21) for CVD (1.19 (1.12-1.27) for IHD mortality, and 1.22 (1.09-1.36) for IS mortality), and 0.90 (0.87-0.94) for all-cancer mortality (0.94 (0.87-1.02) for lung cancer, 0.59 (0.53-0.66) for liver cancer, and 0.73 (0.64-0.83) for stomach cancer). In summary, this study revealed a correlation between increased remnant cholesterol levels and an elevated risk of cardiovascular disease mortality, as well as a reduced risk of mortality for certain types of cancer.

Novel and Emerging LDL-C Lowering Strategies: A New Era of Dyslipidemia Management

Atherosclerotic cardiovascular disease (ASCVD) represents a major global health challenge, significantly contributing to mortality rates. This chronic inflammatory condition affecting blood vessels is intricately linked to hypercholesterolemia, with elevated levels of low-density lipoprotein cholesterol (LDL-C) recognized as a central and modifiable risk factor. The effectiveness of lipid-lowering therapy (LLT) in mitigating ASCVD risk is well established, with studies revealing a substantial reduction in major ischemic events correlating with LDL-C reduction. While statins, often combined with ezetimibe, remain fundamental in dyslipidemia management, a significant proportion of patients on statin therapy continue to experience cardiovascular events. Recent pharmacological advancements, driven by a deeper understanding of atherogenesis, have unveiled novel therapeutic targets and potent drugs. Notably, agents like bempedoic acid and proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors (evolocumab, alirocumab, inclisiran) have emerged as effective options to intensify LLT and achieve LDL-C goals, addressing limitations associated with statins, such as myopathy. Molecular insights into alternative pathways have spurred the investigation of emerging agents, offering promising perspectives for novel medications with efficacy comparable to established treatments, associated with advantages in cost and administration. This review provides a comprehensive overview of the evolving landscape of lipid-lowering strategies, highlighting the progress made in addressing ASCVD risk and the potential of upcoming therapies to further optimize cardiovascular prevention.

Lipid-Lowering Therapy and Risk of Hemorrhagic Stroke: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

BACKGROUND

There is debate over whether statins increase risk of hemorrhagic stroke, so we assessed current evidence, including data from new statin trials and trials of nonstatin low-density lipoprotein-cholesterol (LDL-C)- and triglyceride-lowering therapies.

METHODS AND RESULTS

We performed a systematic review of large randomized clinical trials (≥1000 patients with ≥2 years follow-up) of LDL-C-lowering therapy (statin, ezetimibe, and PCSK-9 [proprotein convertase subtilisin/kexin type 9] inhibitor) and triglyceride-lowering therapy (omega-3 supplements and fibrate) that reported hemorrhagic stroke as an outcome. We searched MEDLINE, Embase, and Cochrane Library up to July 2, 2021 and updated a meta-analysis of cardiovascular statin trials published in 2012. Among our several subgroup analyses, we looked at difference depending on stroke status and also depending on age. We identified 37 trials for LDL-C lowering (284 301 participants) and 11 for triglyceride lowering (120 984 participants). Overall, we found a higher risk of hemorrhagic stroke for LDL-C lowering, risk ratio (RR) 1.16 (95% CI, 1.01-1.32, P=0.03). For statins (33 trials, 216 258 participants), RR=1.17 (95% CI, 1.01-1.36); for PCSK-9 inhibitors (2 trials, 46 488 participants), RR=0.86 (95% CI, 0.43-1.74); and for ezetimibe (2 trials, 21 555 participants), RR=1.14 (95% CI, 0.64-2.03). In statin trials of patients with previous stroke/transient ischemic attack, RR was 1.46 (95% CI, 1.05-2.04), and in trials with mean age ≥65 years old, RR=1.34 (95% CI, 1.04-1.73) (Pint=0.14 and Pint=0.23 respectively); for triglyceride lowering (11 trials, 120 984 participants), RR=1.05 (95% CI, 0.86-1.30).

CONCLUSIONS

We found evidence for a small increased risk of hemorrhagic stroke events with LDL-C-lowering therapies but no clear evidence for triglyceride-lowering therapies.

Achievement of target LDL-cholesterol level in patients with acute coronary syndrome undergoing percutaneous coronary intervention: The JET-LDL registry

BACKGROUND

In patients with acute coronary syndromes (ACS), current guidelines recommend a low-density lipoprotein cholesterol (LDL-C) level < 1.4 mmol/L (<55 mg/dL).

METHODS

The JET-LDL is a multicenter, observational, prospective registry created to investigate levels of LDL-C in consecutive patients with ACS undergoing PCI at 35 Italian hospitals, and to report their lipid lowering therapies (LLT). Follow-up was planned at 1 and 3 months. LDL-C reduction >50% from baseline or level < 55 mg/dL at 1-month was the primary endpoint.

RESULTS

A total of 1095 patients were included: median age was 67 (58-75); 33.7% were already on LLT. Baseline LDL-C levels was 105 (76.5-137) mg/dL. At hospital discharge all patients were on LLT: 98.1% received statins (as mono or combination therapy), ezetimibe and PCSK9i were used in 60.1% and 8.5% of cases, respectively. Primary endpoint was achieved in 62% (95% CI 58-65) of cases. At 1-month LDL-C levels dropped to 53 (38-70) mg/dL (p < 0.001 vs baseline) and it was <55 mg/dL in 53% (95% CI 49-57) of patients; however, PCSK9i were added to 7 further cases. At 3-months 58% (95% CI 55-62) of patients achieved the target level, but PCSK9i was added to only 11 new patients.

CONCLUSIONS

In this real-world registry of ACS patients undergoing PCI, recommend LDL-C levels were obtained in 62% of patients, but PCSK9i prescription was limited to 10% of cases. As LLT pattern appeared mainly improved at hospital discharge, an early and strong treatment should be considered.

Impact of Guideline-Directed Management Strategies for Low-Density Lipoprotein Cholesterol Control in Patients Who Underwent Percutaneous Coronary Intervention

There are little direct comparative evidences of strategies between ≥50% and the absolute target goal of low-density lipoprotein cholesterol (LDL-C) level <55 mg/100 ml for the patients who underwent percutaneous coronary intervention (PCI). This study aimed to investigate the clinical impact of different strategies between 2 groups of patients who underwent PCI. A total of 3,104 patients with previous PCI were retrospectively enrolled from 2014 to 2020 at Yeungnam University Medical Center. The study population was stratified into 2 groups based on whether the LDL-C level was <55 mg/100 ml at the 1-year mark or not. Furthermore, the 50% reduction rate of LDL-C was also categorized based on whether it had decreased by ≥50% from the initial LDL-C level at the 1-year mark. The primary end point was 3-year major adverse cardiovascular events (MACEs) which were defined as a composite of cardiovascular death, nonfatal myocardial infarction, target lesion revascularization, hospitalization for heart failure, or nonfatal stroke. There was no significant difference between the LDL <55 mg/100 ml group and the LDL ≥55 mg/100 ml group in the risk of MACEs (hazard ratio 1.06, 95% confidence interval 0.81 to 1.38, p = 0.690) after propensity score matching. However, the group that achieved ≥50% reduction of LDL-C from baseline LDL-C level showed a significant reduction in the occurrence of MACEs in the subgroup of LDL-C level ≥55 mg/100 ml (hazard ratio 0.41, 95% confidence interval 0.19 to 0.89, p = 0.025) compared with the group with <50% reduction of LDL-C. In all patients, the achievement rate of target LDL-C <55 mg/100 ml and more than 50% reduction from baseline was 17.2%. In conclusion, guideline-directed management strategy of ≥50% reduction of LDL-C from the baseline will be needed to reduce the incidence of MACEs in patients with LDL-C ≥55 mg/100 ml who underwent PCI. Additional efforts to increase the target goal achievement rate of LDL-C are warranted.

The effect of fibrates on lowering low-density lipoprotein cholesterol and cardiovascular risk reduction: a systemic review and meta-analysis

AIMS

The effect of fibrate treatment on cardiovascular risk is inconsistent. This meta-analysis aimed to assess the effect of fibrates on major adverse cardiovascular outcome (MACE) reduction.

METHODS AND RESULTS

PubMed, Embase, and Cochrane library databases were searched up to February 2023 for randomized controlled trials comparing fibrate therapy against placebo and reporting cardiovascular outcomes and lipid profile changes. The primary outcome was the clinical outcomes of each trial that most closely corresponding to MACE, a composite of cardiovascular death, acute myocardial infarction, stroke, and coronary revascularization. A pre-specified meta-regression analysis to examine the relationship between the changes in lipid levels after fibrate treatment and the risk of MACE was also performed. Twelve trials were selected for final analysis, with 25 781 patients and 2741 MACEs in the fibrate group and 27 450 patients and 3754 MACEs in the control group. Overall, fibrate therapy was associated with decreased risk of MACE [RR 0.87, 95% confidence interval (CI) 0.81-0.94] with moderate heterogeneity (I2 = 47%). In meta-regression analysis, each 1 mmol/L reduction in low-density lipoprotein cholesterol (LDL-C) after fibrate treatment reduced MACE (RR 0.71, 95% CI 0.49-0.94, P = 0.01), while triglyceride level changes did not show a significant association (RR per 1mmol/L reduction 0.96, 95% CI 0.53-1.40, P = 0.86). A sensitivity analysis with the composite outcome of cardiovascular death or acute myocardial infarction produced similar results.

CONCLUSION

Treatment with fibrates was associated with decreased risk of MACE. The reduction in MACE risk with fibrate therapy appears to be attributable to LDL-C reduction rather than a decrease in triglyceride levels.

Post-treatment level of LDL cholesterol and all-cause mortality in patients with atherosclerotic cardiovascular disease: evidence from real-world setting

AIMS

This study aimed to evaluate the safety of the currently recommended target of LDL cholesterol (LDL-C) control on mortality in patients with atherosclerotic cardiovascular disease (ASCVD).

METHODS AND RESULTS

Using deidentified electronic health record data, we conducted a multicentre retrospective cohort study involving individuals with documented ASCVD who had received statin treatment for at least 3 months across China. The primary outcomes assessed encompassed all-cause mortality, CV mortality, and non-CV mortality. Relationships between post-treatment LDL-C concentrations and outcomes were evaluated using restricted cubic spline curves based on Cox proportional hazards regression analyses. Additionally, competitive risk models were employed to explore associations between LDL-C levels and cause-specific mortality. Among 33 968 participants, we identified nearly linear associations of post-treatment LDL-C level with all-cause mortality and CV mortality during a median follow-up of 47 months. Notably, patients who achieved the recommended target of LDL-C (<1.4 mmol/L) were at significantly lower risks of all-cause mortality [hazard ratio (HR), 0.77; 95% confidence interval (CI), 0.69-0.86] and CV mortality (subdistribution HR, 0.68; 95% CI, 0.58-0.79), compared with those with LDL-C ≥ 3.4 mmol/L. This survival benefit was consistent in patients with different intensities of LDL-C reduction and other subgroup analyses. And no correlation was found between post-treatment LDL-C concentration and non-CV mortality.

CONCLUSION

Our findings supported the safety of currently recommended target of LDL-C control and the 'lower is better' principle in patients with ASCVD.

Beyond antithrombotics: recent advances in pharmacological risk factor management for secondary stroke prevention

Patients with ischaemic stroke represent a diverse group with several cardiovascular risk factors and comorbidities, which classify them as patients at very high risk of stroke recurrence, cardiovascular adverse events or death. In addition to antithrombotic therapy, which is important for secondary stroke prevention in most patients with stroke, cardiovascular risk factor assessment and treatment also contribute significantly to the reduction of mortality and morbidity. Dyslipidaemia, diabetes mellitus and hypertension represent common and important modifiable cardiovascular risk factors among patients with stroke, while early recognition and treatment may have a significant impact on patients' future risk of major cardiovascular events. In recent years, there have been numerous advancements in pharmacological agents aimed at secondary cardiovascular prevention. These innovations, combined with enhanced awareness and interventions targeting adherence and persistence to treatment, as well as lifestyle modifications, have the potential to substantially alleviate the burden of cardiovascular disease, particularly in patients who have experienced ischaemic strokes. This review summarises the evidence on the contemporary advances on pharmacological treatment and future perspectives of secondary stroke prevention beyond antithrombotic treatment.

Quality control to improve LDL-cholesterol management in patients with acute coronary syndromes based on the ACS EuroPath IV project

AIMS

We performed quality control of lipid-lowering therapy (LLT) in patients with acute coronary syndrome (ACS), with a view to proposing corrective actions.

METHODS AND RESULTS

Using a Define Measure Analysis Improve Control (DMAIC) approach applied to data from the ACS EuroPath IV survey, we measured attainment of two quality indicators (QIs) related to lipid-lowering treatment: (i) prescription of high-intensity statins (or equipotent treatment) before discharge, and (ii) proportion with LDL-cholesterol <55 mg/dL (1.4 mmol/L) during follow-up. A total of 530 European cardiologists responded and provided data for up to 5 patients from their centre, for acute and follow-up phases. Corrective measures are proposed to increase the rate of attainment of both QIs. Attainment of the first QI was measured in 929 acute-phase patients, 99% had LLT prescribed at discharge and 75% of patients fulfilled the first QI. Attainment of the second QI was assessed in 1721 patients with follow-up. The second QI was reached in 31% of patients. The DMAIC approach yielded 10 potential changes in prescription, 3 for the first and 7 for the second QI. The overall strategy is 'Fire to Target', i.e. early intensification of the LLT using statins, ezetimibe, bempedoic acid, and proprotein convertase subtilisin/kexin type-9 inhibitors, and is presented as an algorithm for routine application.

CONCLUSION

Quality control for LLT, based on the ACS EuroPath IV survey, detected 10 potential changes in prescription that could enhance attainment of 2 QIs. Whether the Fire to Target strategy will be adopted and effective needs to be assessed in further steps of the EuroPath Quality programme.

Is there a shift from cardiovascular to cancer death in lipid-lowering trials? A systematic review and meta-analysis

BACKGROUND

Lipid-lowering therapy (LLT) reduces cardiovascular (CV) events, but data are conflicting on all-cause mortality, especially among older adults. Though LLT does not induce cancer, some randomized clinical trials (RCTs) found a pattern of increased cancer death under LLT. Our objective was to assess a possible shift from CV to cancer death in LLT trials (i.e. an increase in cancer and decrease in CV death) and to investigate potential subgroups at risk.

METHODS

We performed a systematic review and meta-analysis. We retrieved RCTs from MEDLINE, Embase, and Cochrane Central until 08/2023. We extracted the number of CV and cancer deaths in the treatment vs. in the control arm, calculated the relative risk (RR) by dividing the risk of death in the treatment over the risk of death in the control group and then pooled them using random-effect meta-analysis. We performed subgroup analyses on primary and secondary prevention, and according to different age cut-offs.

RESULTS

We included 27 trials with 188'259 participants (23 statin; 4 ezetimibe trials). The trials reported 4056 cancer deaths, 2061 under LLT and 1995 in control groups. Overall, there was no increased risk of cancer mortality (RR 1.03, 95% confidence interval 0.97-1.10), with no difference between primary and secondary prevention. In the subgroup analyses for RCTs with ≥15% of participants aged ≥75 years, the RR of cancer death was 1.11 (1.00-1.23), while the RR for CV death was 0.96 (0.91-1.01). For RCTs with a mean age ≥ 70 years, the RR for cancer death was 1.21 (0.99-1.47).

CONCLUSION

LLT does not lead to a shift from CV to cancer death. However, there might be a possible shift with a pattern of increased cancer deaths in trials with more older adults, particularly ≥75 years. Individual participant data from LLT trials should be made public to allow further investigations.

Lipid Disorders Management Strategies (2024) in Prediabetic and Diabetic Patients

Dyslipidaemia is a modifiable risk factor commonly associated with diabetes mellitus and prediabetes, with a major impact on the early development of atherosclerotic cardiovascular disease. Various studies have tried to identify the key treatment targets, their optimal values according to patients' CV risk, and the most efficient yet safe therapeutic agents which, alongside lifestyle changes, would improve lipid levels and reduce cardiovascular mortality and morbidity. Currently, there are multiple pharmacologic options that can be used in the management of dyslipidaemia, such as statins, ezetimibe, bempedoic acid, PCSK9 inhibitors, n-3 polyunsaturated fatty acids or fibrates, to name only a few, while many other are under development. In the current setting of a continuously increasing population of patients with metabolic disorders, this review aims to summarise current knowledge regarding lipid disorders and the recommendations of recent guidelines in treating dyslipidaemia in patients with diabetes mellitus or prediabetes.

Low-Density Lipoprotein Cholesterol-Lowering Drugs: A Narrative Review

The modern history of cholesterol-lowering drugs started in 1972 when Dr. Akira Endo identified an active compound (compactin) that inhibited cholesterol biosynthesis from the culture broth of blue-green mold (Penicillium citrinum Pen-51). Since 1987, statins have represented the milestone for the treatment of atherosclerotic cardiovascular disease. A new therapy for the treatment of hypercholesterolemia since the discovery of statins is ezetimibe, the first and only agent inhibiting intestinal cholesterol absorption. Ezetimibe was approved by the FDA in October 2002. A year later, the association between gain-of-function PCSK9 genetic mutations and hypercholesterolemia was reported, and this discovery opened a new era in lipid-lowering therapies. Monoclonal antibodies and small-interfering RNA approaches to reduce PCSK9 were developed and approved for clinical use in 2015 and 2022, respectively. Finally, the newly approved bempedoic acid, an oral adenosine triphosphate citrate lyase inhibitor that lowers LDL-C, is able to reduce major adverse cardiovascular events in both primary and secondary prevention. In the present narrative review, we summarize the pharmacological properties and the clinical efficacy of all these agents currently used for a tailored therapy of hypercholesterolemia in patients with atherosclerotic cardiovascular disease.

Lipid-lowering drugs and cancer: an updated perspective

Statins and non-statin medications used for the management of dyslipidemia have been shown to possess antitumor properties. Since the use of these drugs has steadily increased over the past decades, more knowledge is required about their relationship with cancer. Lipid-lowering agents are heterogeneous compounds; therefore, it remains to be revealed whether anticancer potential is a class effect or related to them all. Here, we reviewed the literature on the influence of lipid-lowering medications on various types of cancer during development or metastasis. We also elaborated on the underlying mechanisms associated with the anticancer effects of antihyperlipidemic agents by linking the reported in vivo and in vitro studies.

Macrophage mediators and mechanisms in cardiovascular disease

Macrophages are major players in myocardial infarction (MI) and atherosclerosis, two major cardiovascular diseases (CVD). Atherosclerosis is caused by the buildup of cholesterol-rich lipoproteins in blood vessels, causing inflammation, vascular injury, and plaque formation. Plaque rupture or erosion can cause thrombus formation resulting in inadequate blood flow to the heart muscle and MI. Inflammation, particularly driven by macrophages, plays a central role in both atherosclerosis and MI. Recent integrative approaches of single-cell analysis-based classifications in both murine and human atherosclerosis as well as experimental MI showed overlap in origin, diversity, and function of macrophages in the aorta and the heart. We here discuss differences and communalities between macrophages in the heart and aorta at steady state and in atherosclerosis or upon MI. We focus on markers, mediators, and functional states of macrophage subpopulations. Recent trials testing anti-inflammatory agents show a major benefit in reducing the inflammatory burden of CVD patients, but highlight a necessity for a broader understanding of immune cell ontogeny and heterogeneity in CVD. The novel insights into macrophage biology in CVD represent exciting opportunities for the development of novel treatment strategies against CVD.

Patterns of Lipid Lowering Therapy Use Among Older Adults in a Managed Care Advantage Plan in the United States

Background: The prevalence of cardiovascular events is increasing. There are many new lipids lowering therapies available in recent years. Increased evidence through literature and guidelines suggests that the use of lipid lowering therapy (LLT) benefits patients who are at risk for cardiovascular events. Objective: The objective of this study was to describe the current LLT use as well as patterns of treatment modification among adults ≥ 65 years. Methods: A retrospective analysis of administrative claims data between January 2016 and May 2018 was conducted. Patients with a LLT refill and continuous enrollment during 1-year prior and 1-year follow-up were identified. The treatment episodes captured were interruption of therapy, intensity changes, dose changes, treatment augmentation, switching, and discontinuation. An analysis of treatment patterns among patients ≥75 years was also performed. Results: The study included 14,360 patients with a LLT of which 99% of patients were on statins as monotherapy or combination. Overall non-statin therapy use either as monotherapy or combination was 2.1%. There were significant differences among new initiators and existing users of therapy. Among prevalent users 57.4% had no changes in the follow-up period, 13.6% interrupted therapy, and 6.6% discontinued. Among new users, 47.9% patients had interrupted therapy, 25% had no changes, and 21.9% discontinued therapy. Conclusion: Most patients were on monotherapy and statins with low non-statin use. The new users among them were more likely to discontinue and interrupt therapy, highlighting the limitations and issues that older patients face that need to increase adherence.

Association between multiple inflammatory biomarkers and remnant cholesterol levels in patients with percutaneous coronary intervention: A large-scale real-world study

BACKGROUND AND AIM

Remnant cholesterol (RC) has garnered increasing attention recently due to its association with adverse cardiovascular events. However, the relationship between RC levels and inflammation remains unclear. The goal of this study was to investigate and compare the predictive value of multiple inflammatory biomarkers for high RC in patients with percutaneous coronary intervention (PCI).

METHODS AND RESULTS

Initially, a total of 10,724 consecutive individuals hospitalized for PCI at Fu Wai Hospital in 2013 were enrolled. Finally, 9983 patients receiving dual antiplatelet therapy and drug-eluting stent were selected for analysis. The inflammatory biomarkers included high-sensitivity C-reactive protein (hs-CRP), hs-CRP-to-albumin ratio (CAR), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), lymphocyte-to-hs-CRP ratio (LCR), and systemic immune-inflammation index (SII). Patients were divided into higher RC and lower RC groups based on the median RC level. Multivariate logistic regression showed that hs-CRP (OR per SD: 1.254), CAR (OR per SD: 1.245), PLR (OR per SD: 1.139), and SII (OR per SD: 1.077) were associated with high RC (≥median), while LCR (OR per SD: 0.792) was associated with low RC (

CONCLUSIONS

In PCI patients, hs-CRP, CAR, PLR, LCR, and SII were independently associated with RC levels. Among these inflammatory biomarkers, hs-CRP conferred better prediction for high RC. This investigation further supports the close relationship between inflammation and residual lipid risk biomarker RC.

Real-world effectiveness and safety of evolocumab in very high-risk atherosclerotic cardiovascular disease patients with acute ischemic stroke

BACKGROUND

We investigated evolocumab's real-world effectiveness and safety on a background of statin therapy in the acute phase of ischemic stroke (IS) patients with a very high-risk of atherosclerotic cardiovascular disease (ASCVD).

METHODS

A real-world, single-center, retrospective study was conducted in the neurology department at Tianjin Huanhu Hospital in China. Patients were divided into two groups: evolocumab treatment (140 mg every two weeks) or the standard of care (SOC) group. The primary efficacy outcome of the study was the achievement of a targeted lipid control rate and the incidence of major adverse cardiovascular events (MACE) by the end of the follow-up. MACE was defined as a composite of various cardiovascular events, cerebrovascular events such as stroke or TIA, and event-related deaths. Propensity score matching (PSM) analysis was utilized to account for confounding factors between groups. Survival analyses were performed using the Kaplan-Meier method and COX regression modeling.

RESULTS

1080 AIS patients with very high-risk ASCVD were recruited. After PSM, there were 528 individuals, with 206 in the evolocumab group and 322 in the SOC group. At 12 months of follow-up, the proportion of LDL-C < 1.4mmol/L and ≥ 50% reduction was 44.91% in the evolocumab group, compared with only 3.12% of SOC-treated patients (p < 0.01). The median follow-up time for clinical events was 15 months. The evolocumab group was associated with a lower risk of cerebrovascular events compared to the SOC group (HR, 0.45; 95% CI, 0.23-0.89; p = 0.02).

CONCLUSIONS

This real-world study suggested that evolocumab on a background of statin reduced the LDL-C levels significantly and lowered the incidence of recurrent cerebrovascular events in the very high-risk ASCVD patients with AIS in China.

Potential Benefits and Risks Associated with the Use of Statins

HMG-CoA reductase inhibitors, commonly known as statins, are the primary treatment choice for cardiovascular diseases, which stand as the leading global cause of mortality. Statins also offer various pleiotropic effects, including improved endothelial function, anti-inflammatory properties, reduced oxidative stress, anti-thrombotic effects, and the stabilization of atherosclerotic plaques. However, the usage of statins can be accompanied by a range of adverse effects, such as the development of type 2 diabetes mellitus, muscular symptoms, liver toxicity, kidney diseases, cataracts, hemorrhagic strokes, and psychiatric complications. These issues are referred to as statin-associated symptoms (SAS) and are relatively infrequent in clinical trials, making it challenging to attribute them to statin use definitively. Therefore, these symptoms can lead to significant problems, necessitating dose adjustments or discontinuation of statin therapy. This review aims to provide a comprehensive overview of the mechanism of action, potential advantages, and associated risks of statin utilization in clinical settings.

Dietary fat quality, plasma atherogenic lipoproteins, and atherosclerotic cardiovascular disease: An overview of the rationale for dietary recommendations for fat intake

The scientific evidence supporting the current dietary recommendations for fat quality keeps accumulating; however, a paradoxical distrust has taken root among many researchers, clinicians, and in parts of the general public. One explanation for this distrust may relate to an incomplete overview of the totality of the evidence for the link between fat quality as a dietary exposure, and health outcomes such as atherosclerotic cardiovascular disease (ASCVD). Therefore, the main aim of the present narrative review was to provide a comprehensive overview of the rationale for dietary recommendations for fat intake, limiting our discussion to ASCVD as outcome. Herein, we provide a core framework - a causal model - that can help us understand the evidence that has accumulated to date, and that can help us understand new evidence that may become available in the future. The causal model for fat quality and ASCVD is comprised of three key research questions (RQs), each of which determine which scientific methods are most appropriate to use, and thereby which lines of evidence that should feed into the causal model. First, we discuss the link between low-density lipoprotein (LDL) particles and ASCVD (RQ1); we draw especially on evidence from genetic studies, randomized controlled trials (RCTs), epidemiology, and mechanistic studies. Second, we explain the link between dietary fat quality and LDL particles (RQ2); we draw especially on metabolic ward studies, controlled trials (randomized and non-randomized), and mechanistic studies. Third, we explain the link between dietary fat quality, LDL particles, and ASCVD (RQ3); we draw especially on RCTs in animals and humans, epidemiology, population-based changes, and experiments of nature. Additionally, the distrust over dietary recommendations for fat quality may partly relate to an unclear understanding of the scientific method, especially as applied in nutrition research, including the process of developing dietary guidelines. We therefore also aimed to clarify this process. We discuss how we assess causality in nutrition research, and how we progress from scientific evidence to providing dietary recommendations.

Obicetrapib: Reversing the Tide of CETP Inhibitor Disappointments

PURPOSE OF REVIEW

To discuss the history of cardiovascular outcomes trials of cholesteryl ester transfer protein (CETP) inhibitors and to describe obicetrapib, a next-generation, oral, once-daily, low-dose CETP inhibitor in late-stage development for dyslipidemia and atherosclerotic cardiovascular disease (ASCVD).

RECENT FINDINGS

Phase 1 and 2 trials have evaluated the safety and lipid/lipoprotein effects of obicetrapib as monotherapy, in conjunction with statins, on top of high-intensity statins (HIS), and with ezetimibe on top of HIS. In ROSE2, 10 mg obicetrapib monotherapy and combined with 10 mg ezetimibe, each on top of HIS, significantly reduced low-density lipoprotein cholesterol (LDL-C), non-high-density lipoprotein cholesterol (non-HDL-C), apolipoprotein B, total LDL particles, small LDL particles, small, dense LDL-C, and lipoprotein (a), and increased HDL-C. Phase 3 pivotal registration trials including a cardiovascular outcomes trial are underway. Obicetrapib has an excellent safety and tolerability profile and robustly lowers atherogenic lipoproteins and raises HDL-C. As such, obicetrapib may be a promising agent for the treatment of ASCVD.

Lipid-lowering therapy and risk-based LDL-C goal attainment in Belgium: DA VINCI observational study

BACKGROUND

Cardiovascular disease (CVD) is one of the leading causes of death in Belgium. Current strategies for the prevention and management of CVD focus on reducing low-density lipoprotein cholesterol (LDL-C) levels. This analysis assessed whether LDL-C goals, recommended by the European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS) guidelines, were being achieved in a Belgian study population.

METHODS

The cross-sectional, observational, DA VINCI study enrolled patients prescribed lipid-lowering therapy (LLT) between 21 June 2017 and 20 November 2018. Data for patients from Belgium were extracted for this country-specific analysis. Primary endpoint was the proportion of patients who achieved 2016 ESC/EAS risk-based LDL-C goals; attainment of 2019 risk-based LDL-C goals was evaluated post hoc.

RESULTS

Of 497 enrolled patients, 41% were female and mean age was 68 years. Among subjects with an LDL-C measurement on stabilised LLT, moderate-intensity statin monotherapy was the most prescribed LLT regimen (59%). Overall, 63% of patients achieved their risk-based LDL-C goals according to the 2016 ESC/EAS guidelines. Among patients with established ASCVD, risk-based LDL-C goal attainment was higher in patients with peripheral arterial disease (53%) than patients with coronary (37%) and cerebrovascular disease (42%). According to the updated 2019 ESC/EAS guidelines, less than half (41%) of patients achieved their risk-based LDL-C goal. The proportion of primary and secondary prevention patients who achieved 2019 risk-based LDL-C goals was 59% and 18%, respectively.

CONCLUSION

These findings reveal a large gap between the LDL-C goals advocated by the ESC/EAS and the levels achieved in routine clinical practice in Belgium.

Optimizing Post-Acute Coronary Syndrome Dyslipidemia Management: Insights from the North American Acute Coronary Syndrome Reflective III

INTRODUCTION

Despite contemporary practice guidelines, a substantial number of post-acute coronary syndrome (ACS) patients fail to achieve guideline-recommended LDL-C thresholds. Our study aimed to investigate this guideline recommendations-to-practice care gap. Specifically, we aimed to identify opportunities where additional lipid-lowering therapies are indicated and explore reasons for the non-prescription of guideline-recommended therapies.

METHODS

ACS patients with LDL-C ≥1.81 mmol/L (70 mg/dL) despite maximally tolerated statin ± ezetimibe therapy (including those intolerant of ≥2 statins) were enrolled 1-12 months post-event from 27 Canadian and US sites from September 2018 to October 2020 and followed up for three visits during the 12 months post-event. We determined the proportion of patients who did not achieve Canadian/US guideline-recommended LDL-C thresholds, the number of patients who would have been eligible for additional lipid-lowering therapies, and reasons behind lack of escalation in lipid-lowering therapies when indicated. Individual patient and aggregate practice feedback, including guideline-recommended intensification suggestions, were provided to each physician.

RESULTS

Of the 248 patients enrolled in the pilot study (median age 64 [57, 73] years, 31.5% female and STEMI 27.4%), 75.4% were on high-intensity statins on the first visit. A total of 18.5% of those who attended all 3 visits had an LDL-C measured only at the first visit which was above the threshold. After 1 year of follow-up, 51.9% of patients achieved LDL-C thresholds at either visit 2 or 3. In the context of feedback reminding physicians about guideline-directed LDL-C-modifying therapy in their individual participating patients, we observed an increase in the use of ezetimibe and PCSK9 inhibitor therapy at 3-12 months. This was associated with a significant lowering of the mean LDL-C (from 2.93 mmol/L [baseline] to 2.09 mmol/L [3-6 months] to 1.87 mmol/L [6-12 months]) and a significantly greater proportion of patients (from 0% [baseline] to 38.6% [3-6 months] to 53.4% [6-12 months]) achieving guideline-recommended LDL-C thresholds. The most prevalent reasons behind the non-intensification of LDL-C-lowering therapy with ezetimibe and/or PCSK9i were LDL-C levels being close to target, the pre-existing use of other lipid-lowering therapies, patient refusal, and cost.

CONCLUSION

Although most patients post-ACS were on high-intensity statin therapy, almost 50% failed to achieve guideline-recommended LDL-C thresholds by 1-year follow-up. Furthermore, additional lipid-lowering therapies in this high-risk group were underprescribed, and this might be linked to several factors including potential gaps in physician knowledge, treatment inertia, patient refusal, and cost.

Major Facilitator Superfamily Domain Containing 5 Inhibition Reduces Lipoprotein(a) Uptake and Calcification in Valvular Heart Disease

BACKGROUND

High circulating levels of Lp(a) (lipoprotein[a]) increase the risk of atherosclerosis and calcific aortic valve disease, affecting millions of patients worldwide. Although atherosclerosis is commonly treated with low-density lipoprotein-targeting therapies, these do not reduce Lp(a) or risk of calcific aortic valve disease, which has no available drug therapies. Targeting Lp(a) production and catabolism may provide therapeutic benefit, but little is known about Lp(a) cellular uptake.

METHODS

Here, unbiased ligand-receptor capture mass spectrometry was used to identify MFSD5 (major facilitator superfamily domain containing 5) as a novel receptor/cofactor involved in Lp(a) uptake.

RESULTS

Reducing MFSD5 expression by a computationally identified small molecule or small interfering RNA suppressed Lp(a) uptake and calcification in primary human valvular endothelial and interstitial cells. MFSD5 variants were associated with aortic stenosis (P=0.027 after multiple hypothesis testing) with evidence suggestive of an interaction with plasma Lp(a) levels.

CONCLUSIONS

MFSD5 knockdown suppressing human valvular cell Lp(a) uptake and calcification, along with meta-analysis of MFSD5 variants associating with aortic stenosis, supports further preclinical assessment of MFSD5 in cardiovascular diseases, the leading cause of death worldwide.

Unveiling Familial Hypercholesterolemia-Review, Cardiovascular Complications, Lipid-Lowering Treatment and Its Efficacy

Familial hypercholesterolemia (FH) is a genetic disorder primarily transmitted in an autosomal-dominant manner. We distinguish two main forms of FH, which differ in the severity of the disease, namely homozygous familial hypercholesterolemia (HoFH) and heterozygous familial hypercholesterolemia (HeFH). The characteristic feature of this disease is a high concentration of low-density lipoprotein cholesterol (LDL-C) in the blood. However, the level may significantly vary between the two mentioned types of FH, and it is decidedly higher in HoFH. A chronically elevated concentration of LDL-C in the plasma leads to the occurrence of certain abnormalities, such as xanthomas in the tendons and skin, as well as corneal arcus. Nevertheless, a significantly more severe phenomenon is leading to the premature onset of cardiovascular disease (CVD) and its clinical implications, such as cardiac events, stroke or vascular dementia, even at a relatively young age. Due to the danger posed by this medical condition, we have investigated how both non-pharmacological and selected pharmacological treatment impact the course of FH, thereby reducing or postponing the risk of clinical manifestations of CVD. The primary objective of this review is to provide a comprehensive summary of the current understanding of FH, the effectiveness of lipid-lowering therapy in FH and to explain the anatomopathological correlation between FH and premature CVD development, with its complications.

The role of structured inpatient lipid protocols in optimizing non-statin lipid lowering therapy: a review and single-center experience

Dyslipidemia is a leading contributor to atherosclerotic cardiovascular disease (ASCVD). There has been a significant improvement in the treatment of dyslipidemia in the past 10 years with the development of new pharmacotherapies. The intent of this review is help enhance clinicians understanding of non-statin lipid lowering therapies in accordance with the 2022 American College of Cardiology Expert Consensus Clinical Decision Pathway on the Role of Non-statin Therapies for LDL-Cholesterol Lowering. We also present a single-center experience implementing a systematic inpatient protocol for lipid lowering therapy for secondary prevention of ASCVD.

Screening, identifying, and treating chronic kidney disease: why, who, when, how, and what?

1 in 7 American adults have chronic kidney disease (CKD); a disease that increases risk for CKD progression, cardiovascular events, and mortality. Currently, the US Preventative Services Task Force does not have a screening recommendation, though evidence suggests that screening can prevent progression and is cost-effective. Populations at risk for CKD, such as those with hypertension, diabetes, and age greater than 50 years should be targeted for screening. CKD is diagnosed and risk stratified with estimated glomerular filtration rate utilizing serum creatinine and measuring urine albumin-to-creatinine ratio. Once identified, CKD is staged according to C-G-A classification, and managed with lifestyle modification, interdisciplinary care and the recently expanding repertoire of pharmacotherapy which includes angiotensin converting enzyme inhibitors or angiotensin-II receptor blockers, sodium-glucose-cotransporter-2 inhibitors, and mineralocorticorticoid receptor antagonists. In this paper, we present the why, who, when, how, and what of CKD screening.

Current Status and Principles for the Treatment and Prevention of Diabetic Foot Ulcers in the Cardiovascular Patient Population: A Scientific Statement From the American Heart Association

Despite the known higher risk of cardiovascular disease in individuals with type 2 diabetes, the pathophysiology and optimal management of diabetic foot ulcers (DFUs), a leading complication associated with diabetes, is complex and continues to evolve. Complications of type 2 diabetes, such as DFUs, are a major cause of morbidity and mortality and the leading cause of major lower extremity amputation in the United States. There has recently been a strong focus on the prevention and early treatment of DFUs, leading to the development of multidisciplinary diabetic wound and amputation prevention clinics across the country. Mounting evidence has shown that, despite these efforts, amputations associated with DFUs continue to increase. Furthermore, due to increasing patient complexity of management secondary to comorbid conditions, such as cardiovascular disease, the management of peripheral artery disease associated with DFUs has become increasingly difficult, and care delivery is often episodic and fragmented. Although structured, process-specific approaches exist at individual institutions for the management of DFUs in the cardiovascular patient population, there is insufficient awareness of these principles in the general medicine communities. Furthermore, there is growing interest in better understanding the mechanistic underpinnings of DFUs to better define personalized medicine to improve outcomes. The goals of this scientific statement are to provide salient background information on the complex pathogenesis and current management of DFUs in cardiovascular patients, to guide therapeutic and preventive strategies and future research directions, and to inform public policy makers on health disparities and other barriers to improving and advancing care in this expanding patient population.

The Impact of the Mediterranean Diet and Lifestyle Intervention on Lipoprotein Subclass Profiles among Metabolic Syndrome Patients: Findings of a Randomized Controlled Trial

Metabolic syndrome (MetS) is associated with alterations of lipoprotein structure and function that can be characterized with advanced lipoprotein testing (ADLT). The effect of the Mediterranean diet (MedDiet) and weight loss on the lipoprotein subclass profile has been scarcely studied. Within the PREDIMED-Plus randomized controlled trial, a sub-study conducted at Bellvitge Hospital recruiting center evaluated the effects of a weight loss program based on an energy-reduced MedDiet (er-MedDiet) and physical activity (PA) promotion (intervention group) compared with energy-unrestricted MedDiet recommendations (control group) on ADLT-assessed lipoprotein subclasses. 202 patients with MetS (n = 107, intervention; n = 95, control) were included. Lipid profiles were determined, and ADLT was performed at baseline, 6, and 12 months. Linear mixed models were used to assess the effects of intervention on lipoprotein profiles. Compared to the control diet, at 12 months, the er-MedDiet+PA resulted in a significant additional 4.2 kg of body weight loss, a decrease in body mass index by 1.4 kg/m2, reduction in waist circumference by 2.2 cm, decreased triglycerides, LDL-cholesterol and non-HDL-cholesterol, and increased HDL-cholesterol. In er-MedDiet+PA participants, ADLT revealed a decrease in small dense-LDL-cholesterol (sd-LDL-C), intermediate-density lipoproteins, VLDL-triglyceride, and HDL-Triglyceride, and an increase in large LDL and large VLDL particles. In conclusion, compared to an ad libitum MedDiet (control group), er-MedDiet+PA decreased plasma triglycerides and the triglyceride content in HDL and VLDL particles, decreased sd-LDL-C, and increased large LDL particles, indicating beneficial changes against cardiovascular disease.

An Analysis of the Gut Microbiota and Related Metabolites following PCSK9 Inhibition in Statin-Treated Patients with Elevated Levels of Lipoprotein(a)

BACKGROUND

Atherosclerotic cardiovascular disease (ASCVD) is a leading cause of global mortality, often associated with high blood levels of LDL cholesterol (LDL-c). Medications like statins and PCSK9 inhibitors, are used to manage LDL-c levels and reduce ASCVD risk. Recent findings connect the gut microbiota and its metabolites to ASCVD development. We showed that statins modulate the gut microbiota including the production of microbial metabolites involved in the regulation of cholesterol metabolism such as short chain fatty acids (SCFAs) and bile acids (BAs). Whether this pleiotropic effect of statins is associated with their antimicrobial properties or it is secondary to the modulation of cholesterol metabolism in the host is unknown. In this observational study, we evaluated whether alirocumab, a PCSK9 inhibitor administered subcutaneously, alters the stool-associated microbiota and the profiles of SCFAs and BAs.

METHODS

We used stool and plasma collected from patients enrolled in a single-sequence study using alirocumab. Microbial DNA was extracted from stool, and the bacterial component of the gut microbiota profiled following an amplicon sequencing strategy targeting the V3-V4 region of the 16S rRNA gene. Bile acids and SCFAs were profiled and quantified in stool and plasma using mass spectrometry.

RESULTS

Treatment with alirocumab did not alter bacterial alpha (Shannon index, p = 0.74) or beta diversity (PERMANOVA, p = 0.89) in feces. Similarly, circulating levels of SCFAs (mean difference (95% confidence interval (CI)), 8.12 [-7.15-23.36] µM, p = 0.25) and BAs (mean difference (95% CI), 0.04 [-0.11-0.19] log10(nmol mg-1 feces), p = 0.56) were equivalent regardless of PCSK9 inhibition. Alirocumab therapy was associated with increased concentration of BAs in feces (mean difference (95% CI), 0.20 [0.05-0.34] log10(nmol mg-1 feces), p = 0.01).

CONCLUSION

In statin-treated patients, the use of alirocumab to inhibit PCSK9 leads to elevated levels of fecal BAs without altering the bacterial population of the gut microbiota. The association of alirocumab with increased fecal BA concentration suggests an additional mechanism for the cholesterol-lowering effect of PCSK9 inhibition.

Intermediate and long-term residual cardiovascular risk in patients with established cardiovascular disease treated with statins

Introduction

Statins remain the first-line treatment for secondary prevention of cardiovascular (CV) events, with lowering of low-density lipoprotein cholesterol (LDL-C) being their therapeutic target. Although LDL-C reduction significantly lowers CV risk, residual risk persists, even in patients with well-controlled LDL-C; thus, statin add-on agents that target pathways other than LDL-C, such as the omega-3 fatty acid eicosapentaenoic acid, may help to further reduce persistent CV risk in patients with established CV disease.

Methods

This narrative review examines the contemporary literature assessing intermediate- and long-term event rates in patients with established CV disease treated with statins.

Results

CV event rates among patients treated with statins who have established CV disease, including coronary artery disease, cerebrovascular disease, or peripheral arterial disease, accumulate over time, with a cumulative incidence of CV events reaching up to approximately 40% over 10 years. Recurrent stroke occurs in up to 19% of patients seven years after a first cerebrovascular event. Repeat revascularization and CV-related death occurs in up to 38% and 33% of patients with peripheral artery disease after three years, respectively.

Discussion

Additional treatment strategies, such as eicosapentaenoic acid, are needed to reduce persistent CV risk in patients with established CV disease treated with statins.

Comparative effectiveness of moderate-intensity statin with ezetimibe therapy versus high-intensity statin monotherapy in patients with acute coronary syndrome: a nationwide cohort study

The long-term outcome of first-line moderate-intensity statin with ezetimibe combination therapy for secondary prevention after percutaneous coronary intervention in patients with acute coronary syndrome (ACS) compared to high-intensity statin monotherapy remains elusive. The objective of this study was to compare the effectiveness of moderate-intensity statin and ezetimibe combination therapy with high-intensity statin monotherapy. We conducted a nationwide, population-based, retrospective, cohort study of patients with ACS from 2013 to 2019. The patients using combination therapy were matched (1:1) to those using monotherapy. The primary outcome was a composite of myocardial infarction, stroke and all-cause mortality. We estimated the hazard ratios (HR) and 95% confidence intervals (CIs) using the Cox proportional hazards regression. After propensity score matching, 10,723 pairs were selected. Men accounted for 70% of the patients and 37% aged > 70 years. The primary endpoint occurred in 1297 patients (12.1%) in the combination group and in 1426 patients (13.3%) in the monotherapy group, and decreased risk (HR 0.85, 95% CI 0.78-0.92, P < 0.001) in the combination group. Among the patients with ACS, moderate-intensity statin with ezetimibe combination therapy was associated with decreased risk of adverse cardiovascular outcomes compared with high-intensity statin monotherapy in a nationwide population-based study representing routine clinical practice.

Inflammation in acute myocardial infarction: the good, the bad and the ugly

Convergent experimental and clinical evidence have established the pathophysiological importance of pro-inflammatory pathways in coronary artery disease. Notably, the interest in treating inflammation in patients suffering acute myocardial infarction (AMI) is now expanding from its chronic aspects to the acute setting. Few large outcome trials have proven the benefits of anti-inflammatory therapies on cardiovascular outcomes by targeting the residual inflammatory risk (RIR), i.e. the smouldering ember of low-grade inflammation persisting in the late phase after AMI. However, these studies have also taught us about potential risks of anti-inflammatory therapy after AMI, particularly related to impaired host defence. Recently, numerous smaller-scale trials have addressed the concept of targeting a deleterious flare of excessive inflammation in the early phase after AMI. Targeting different pathways and implementing various treatment regimens, those trials have met with varied degrees of success. Promising results have come from those studies intervening early on the interleukin-1 and -6 pathways. Taking lessons from such past research may inform an optimized approach to target post-AMI inflammation, tailored to spare 'The Good' (repair and defence) while treating 'The Bad' (smouldering RIR) and capturing 'The Ugly' (flaming early burst of excess inflammation in the acute phase). Key constituents of such a strategy may read as follows: select patients with large pro-inflammatory burden (i.e. large AMI); initiate treatment early (e.g. ≤12 h post-AMI); implement a precisely targeted anti-inflammatory agent; follow through with a tapering treatment regimen. This approach warrants testing in rigorous clinical trials.

LDL cholesterol target attainment in cardiovascular high- and very-high-risk patients with statin intolerance: a simulation study

The inability to tolerate sufficient doses of statins, statin intolerance (SI), contributes to the non-achievement of guideline-recommended low-density lipoprotein cholesterol (LDL-C) treatment targets. Patients with SI require alternative lipid-lowering therapies (LLT). We conducted a simulation study on LDL-C target achievement with oral LLT (ezetimibe, bempedoic acid) in patients with SI, using representative data of 2.06 million German outpatients. SI was defined using literature-informed definitions based on electronic medical records (EMR). Among n = 130,778 patients with hypercholesterolaemia, available LDL-C measurement, and high or very-high cardiovascular risk, 8.6% met the definition of SI. Among patients with SI, 7.7% achieved the LDL-C target at baseline. After simulation of the stepwise addition of treatment with ezetimibe and bempedoic acid, 22.6 and 52.0% achieved the LDL-C target, respectively. The median achieved LDL-C was 80 and 62 mg/dL, the corresponding reductions from baseline were 20.0 and 38.0%, respectively. A higher proportion of patients classified as high risk achieved the target compared to those at very-high risk (58.1 vs. 49.9%). In conclusion, in patients with increased cardiovascular risk meeting the definition of SI based on EMR, combination LLT with ezetimibe and bempedoic acid has the potential to substantially increase the proportion of patients achieving clinically relevant LDL-C reductions.

Dose-Response Associations of Lipid Traits With Coronary Artery Disease and Mortality

Importance

Apolipoprotein B (apoB), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TG) are associated with coronary artery disease (CAD). However, trial evidence for the association of intensive LDL-C lowering and TG lowering with mortality is less definitive.

Objectives

To investigate the associations of apoB, LDL-C, and TG with CAD and mortality, both overall and by sex and age, and to characterize the shapes of these associations.

Design, Setting, and Participants

This genetic association study used linear and nonlinear mendelian randomization (MR) to analyze a population-based cohort of individuals of European ancestry from the UK Biobank, which recruited participants from 2006 to 2010 with follow-up information updated until September 2021. Data analysis occurred from December 2022 to November 2023.

Exposures

Genetically predicted apoB, LDL-C, and TG.

Main Outcomes and Measures

The primary outcomes were CAD, all-cause mortality, and cause-specific mortality. Genetic associations with CAD were calculated using logistic regression, associations with all-cause mortality using Cox proportional hazards regression, and associations with cause-specific mortality using cause-specific Cox proportional hazards regression with censoring for other causes of mortality.

Results

This study included 347 797 participants (mean [SD] age, 57.2 [8.0] years; 188 330 female [54.1%]). There were 23 818 people who developed CAD and 23 848 people who died. Genetically predicted apoB was positively associated with risk of CAD (odds ratio [OR], 1.65 per SD increase; 95% CI 1.57-1.73), all-cause mortality (hazard ratio [HR], 1.11; 95% CI, 1.06-1.16), and cardiovascular mortality (HR, 1.36; 95% CI, 1.24-1.50), with some evidence for larger associations in male participants than female participants. Findings were similar for LDL-C. Genetically predicted TG was positively associated with CAD (OR, 1.60; 95% CI 1.52-1.69), all-cause mortality (HR, 1.08; 95% CI, 1.03-1.13), and cardiovascular mortality (HR, 1.21; 95% CI, 1.09-1.34); however, sensitivity analyses suggested evidence of pleiotropy. The association of genetically predicted TG with CAD persisted but it was no longer associated with mortality outcomes after controlling for apoB. Nonlinear MR suggested that all these associations were monotonically increasing across the whole observed distribution of each lipid trait, with no diminution at low lipid levels. Such patterns were observed irrespective of sex or age.

Conclusions and relevance

In this genetic association study, apoB (or, equivalently, LDL-C) was associated with increased CAD risk, all-cause mortality, and cardiovascular mortality, all in a dose-dependent way. TG may increase CAD risk independent of apoB, although the possible presence of pleiotropy is a limitation. These insights highlight the importance of apoB (or, equivalently, LDL-C) lowering for reducing cardiovascular morbidity and mortality across its whole distribution.

Eradicating Atherosclerotic Events by Targeting Early Subclinical Disease: It Is Time to Retire the Therapeutic Paradigm of Too Much, Too Late

Recent decades have seen spectacular advances in understanding and managing atherosclerotic cardiovascular disease, but paradoxically, clinical progress has stalled. Residual risk of atherosclerotic cardiovascular disease events is particularly vexing, given recognized lifestyle interventions and powerful modern medications. Why? Atherosclerosis begins early in life, yet clinical trials and mechanistic studies often emphasize terminal, end-stage plaques, meaning on the verge of causing heart attacks and strokes. Thus, current clinical evidence drives us to emphasize aggressive treatments that are delayed until patients already have advanced arterial disease. I call this paradigm "too much, too late." This brief review covers exciting efforts that focus on preventing, or finding and treating, arterial disease before its end-stage. Also included are specific proposals to establish a new evidence base that could justify intensive short-term interventions (induction-phase therapy) to treat subclinical plaques that are early enough perhaps to heal. If we can establish that such plaques are actionable, then broad screening to find them in early midlife individuals would become imperative-and achievable. You have a lump in your coronaries! can motivate patients and clinicians. We must stop thinking of a heart attack as a disease. The real disease is atherosclerosis. In my opinion, an atherosclerotic heart attack is a medical failure. It is a manifestation of longstanding arterial disease that we had allowed to progress to its end-stage, despite knowing that atherosclerosis begins early in life and despite the availability of remarkably safe and highly effective therapies. The field needs a transformational advance to shift the paradigm out of end-stage management and into early interventions that hold the possibility of eradicating the clinical burden of atherosclerotic cardiovascular disease, currently the biggest killer in the world. We urgently need a new evidence base to redirect our main focus from terminal, end-stage atherosclerosis to earlier, and likely reversible, human arterial disease.

Targeting inflammation in atherosclerosis: overview, strategy and directions

Atherosclerosis is a chronic condition characterised by the build-up of plaque in the inner lining of the blood vessels and it is the main underlying cause of cardiovascular disease. The development of atherosclerosis is associated with the accumulation of cholesterol and inflammation. Although effective therapies exist to lower low-density lipoprotein cholesterol (LDL-C) levels, some patients still experience cardiovascular events due to persistent inflammation, known as residual inflammatory risk (RIR). Researchers have conducted laboratory and animal studies to investigate the measurement and targeting of the inflammatory cascade associated with atherosclerosis, which have yielded promising results. In addition to guideline-directed lifestyle modifications and optimal medical therapy focusing on reducing LDL-C levels, pharmacological interventions targeting inflammation may provide further assistance in preventing future cardiac events. This review aims to explain the mechanisms of inflammation in atherosclerosis, identifies potential biomarkers, discusses available therapeutic options and their strengths and limitations, highlights future advancements, and summarises notable clinical studies. Finally, an evaluation and management algorithm for addressing RIR is presented.
