Generalizability of SELECT to a contemporary cohort of cardiac surgical patients: analysis of the TRICS III Randomized Trial

Abstract Background The SELECT trial reported a significant reduction in cardiovascular (CV) outcomes with semaglutide amongst patients without diabetes who had pre-existing CV disease and a body-mass index (BMI) of 27 or greater. Patients undergoing cardiac surgery represent a high-risk subset of those with established CV disease, and may benefit from treatment with semaglutide. Purpose This study evaluated the generalizability of SELECT to a contemporary international cohort of cardiac surgical patients, and assessed whether differences between SELECT-eligible and non-eligible patients translated to altered risks of CV outcomes. Methods Present data was gathered from the TRICS III trial, a multicentre, randomized trial of restrictive versus liberal red-cell transfusion thresholds amongst 5243 cardiac surgical patients with a EuroSCORE I of ≥6. The proportion of cardiac surgical patients eligible for SELECT was determined by applying its selection criteria to the TRICS III cohort. Finally, baseline characteristics and outcomes stratified by SELECT eligibility were compared. Results A total of 4887 patients from the TRICS III cohort had available data for analysis, of which 452 (9.2%) were deemed to have been eligible for the SELECT trial. A comparison of baseline characteristics between SELECT-eligible and non-eligible patients are presented in Table 1; while SELECT-eligible patients were more likely to have preserved left ventricular function (71.7% vs. 61.0%), EuroSCORE I values were comparable between the two groups (7.8±2.1 vs. 7.9±1.9). The rate of a 3-point MACCE of Death, MI or stroke in the present cohort of SELECT-eligible patients undergoing cardiac surgery (16.6%) was numerically higher than those enrolled in SELECT receiving semaglutide (8.1%) or placebo (10.0%), despite the shorter follow-up (6 months vs. 39.8 months). Six month outcomes following cardiac surgery were similar regardless of SELECT eligibility (Figure 1); no difference in risk of outcomes was documented for the 3-point MACCE [SELECT Eligible vs. Non-eligible – 16.6% vs. 14.5%; OR 1.17 (0.9-1.53); P=0.24] and the TRICS III primary composite of Death, MI, Stroke, or New-Onset Renal Failure with Dialysis [17.0% vs. 17.0%; OR 1.0 (0.77-1.29); P=0.98]. There was a trend towards higher rates of MI at 6 months amongst SELECT-eligible patients, but this difference failed to reach statistical significance [8.5% vs. 6.3%; OR 2.0 (0.96-1.39); P=0.08). Conclusions In this large international cohort of contemporary cardiac surgical patients, nearly 10% would have met eligibility for SELECT. SELECT-eligible patients undergoing cardiac surgery in TRICS III had a numerically higher rate of MACCE than those enrolled in SELECT, highlighting the high risk nature of this patient subgroup. However, amongst SELECT-eligible and non-eligible patients undergoing cardiac surgery, no significant difference in CV outcomes was uncovered.

Cardiovascular prevention with GLP1 agonists in high or very-high cardiovascular risk irrespective of diabetes

Abstract Introduction Patients with established cardiovascular disease have an increased risk of stroke and myocardial infarction, even in the absence of atrial fibrillation. Several trials have analyzed the effect of glucagon-like peptide-1 receptor (GLP1) agonists in patients with high cardiovascular risk and lately this effect has been studied even in the absence of diabetes. Methods A meta-analysis of randomized clinical trials (RCT) comparing GLP1 agonists with placebo was performed. The primary objective of the study was to analyze the composite endpoint of cardiovascular death, non-fatal myocardial infarction and non-fatal stroke (MACE). As secondary objectives, cardiovascular death, non-fatal myocardial infarction and non-fatal stroke have been studied separately. The meta-analysis was performed using the inverse variance method, using the fixed effects model when there was no heterogeneity and the random effects model when heterogeneity is significant. In the case of significant heterogeneity in the primary objective, a stratified analysis with exposure time have been performed to explain this outcome. Results A sum of 9 randomized controlled trials were included where a GLP1 agonist such as albiglutide, dulaglutide, exenatide, liraglutide, lixinatide or semaglutide was compared with placebo. 77684 patients were incorporated, while 39497 were treated with a GLP1 agonist. The mean age was of 63.7 years (SD ± 1.97 years), 60080 (77.3%) suffered from diabetes and 60552 (77.9%) from cardiovascular disease. As showed in figure 1, the GLP1 agonists showed a reduction of 13% of the MACE (RR: 0.87, 95% CI 0.81-0.92; p<0.001). Heterogeneity could be explained by exposure time and concentration in the blood, considering that it disappears within each group when applying this condition. Treatment with GLP1 agonist also reduced cardiovascular death by 12% (RR: 0.88, 95% CI 0.82-0.94; p<0.001), non-fatal strokes by 14% (RR: 0.86, 95%CI 0.79-0.95; p<0.001) and non-fatal miocardial infarction by 13% (RR: 0.87, 95% CI 0.78-0.97; p<0.001). Conclusion Treatment with a GLP1 agonist reduced the incidence of the MACE by 13% and cardiovascular death by 12%, as well as it decreased the incidence of nonfatal stroke by 14% and of nonfatal myocardial infarction by 13% in different RCTs involving patients with high or very-high cardiovascular risk with or without diabetes.

Large sample size MRI measurements to assess the relation between cardiac function and structure and white matter hyperintensity volumes

Abstract Background People with established cardiovascular disease (CVD) are at risk of early cognitive decline, and neurological diseases such as dementia. CVD and neurological diseases share common risk factors, such as blood pressure, sedentary lifestyle, as well as genomic risk factors such as mutations in APOE4 [1]. It's unclear to what extent the co-occurrence of CVD and neurological diseases is explained by these risk factors, or whether there is a direct association where CVD is a first step towards poorer neurological health. White matter hyperintensities (WMH) of presumed vascular origin are damaged areas in the brain observed through magnetic resonance imaging (MRI). These lesions are associated with progressive neurological disease such as vascular dementia, as well with risk factors for CVD [2]. Purpose We set out to determine to what extent CMR measurements associated with WMH independent of known cerebrovascular risk factors. Methods Cardiac and brain MRI images were analysed for 23,963 UK biobank (UKB) participants. WMH analysis included 5 brain regions (Frontal[F], Parietal[P], Temporal[T], Occipital[O], Basal Ganglia and Thalami [BGT]) and total brain WMH volume. Cardiac traits included stroke volumes, atrial volumes, ejection fractions of right and left chambers, left ventricular (LV) strain, LV wall thickness and aortic areas. Multivariable regression analysis was carried out, where each cardiac trait was regressed on each brain region and adjusted for: age, difference between age at initial visit and imaging visit, sex, systolic and diastolic blood pressure, Hba1c, household income, educational status, Townsend score and family history of disease (Alzheimer’s, Parkinson's, high blood pressure, stroke, heart disease) . Results were evaluated against a multiple testing correct p-value threshold of 0.05, reflecting the number of principle components(n=10) necessary to explain 90% of the cardiac trait variability. Results For 5 cardiac traits (right ventricular stroke volume, left atrial stroke volume, left ventricular stroke volume, left ventricular ejection fraction and right ventricular end diastolic volume) higher values were associated with lower WMH volumes in all brain regions. Additionally, some cardiac traits such as LV cardiac output associated with specific brain regions (T, O, BGT). Additionally, APOE- ε4 stratified analyses indicated, homozygous carriers show a greater association between higher minimum LA and RA volumes and higher WMH volumes in the occipital lobe. Conclusions This study gives an insight into the WMH burden in a large population of adults. It highlights the associations of cardiac traits with white matter hyperintensity volumes in different brain regions independent of known risk factors. Using cardiac traits as surrogate markers of different cardiac disease could explain how cardiac functionality defines WMH volume distribution and subsequently the wider relationship between CVD and cerebrovascular disease.Figure 1Graphical Abstract

Anti-inflammatory effect of semaglutide: updated systematic review and meta-analysis

Abstract Background Glucagon-like peptide-1 (GLP-1RA) receptor agonists possess multiple favourable metabolic, anti-inflammatory effects and their use is associated with marked body weight reduction. More importantly, this drug class has been shown to reduce cardiovascular events in patients with type 2 diabetes mellitus (T2DM) at high cardiovascular risk or with established cardiovascular disease. Accordingly, current guidelines recommend the use of GLP-1RA sas first-line antidiabetic therapies in patients at high cardiovascular risk. Semaglutide is a potent GLP-1RA used in the treatment of T2DM with proven cardiovascular benefits. It is currently available in formulations for oral and subcutaneous administration. The anti-inflammatory effect could be one of the mechanisms by which semaglutide reduces cardiovascular risk in patients with type 2 diabetes mellitus (T2DM) and/or obesity. Determining the anti-inflammatory effect of semaglutide was the objective of this systematic review and meta-analysis. Methods This meta-analysis was performed according to the PRISMA guidelines. A literature search was performed to detect randomised clinical trials that have quantified the effect of semaglutide on C-reactive protein (CRP) levels compared to placebo or a control group (other glucose-lowering drugs). The primary outcome was CRP index (final CRP/basal CRP). A random-effects model was used. Results Overall, this meta-analysis shows that semaglutide therapy was associated with lower CRP index values compared to placebo (SMD -0.56; 95% CI -0.69 to -0.43, I2 92%) or when comparing semaglutide treatment versus a control group consisting of patients medicated with other glucose-lowering drugs (SMD -0.45; 95% CI -0.68 to -0.23, I 3 82%). The stratified analysis was performed by analysing only the trials that used a placebo group as comparator, When the trials were analysed according to the different dosing schemes (subcutaneous vs. oral), the results were not statistically significantly different (oral semaglutide group: SMD -0.33; 95% CI -0.75 to 0.08, I2 95%); semaglutide subcutaneous dose group: SMD -0.69; 95% CI -0.78 to -0.60, I2 74%); interaction p = 0.098. Furthermore, when the trials were analysed according to the included populations (patients with or without T2DM), the results were similar (patients with T2DM: SMD -0.32; 95% CI -0.51 to -0.14, I2 86%); patients without T2DM: SMD -0.82; 95% CI -0.90 to -0.74, I2 58%); interaction p = < 0.0001. Conclusion The present meta-analysis demonstrated that the use of semaglutide was associated with a reduction in inflammation irrespective of the population evaluated or the treatment regimen used. These findings would explain one of the mechanisms by which semaglutide reduces cardiovascular events.

Prediction of 10-year risk for recurrent atherosclerotic cardiovascular events in a secondary prevention population: Insights from CHART-2 and Suita studies in the Japanese population

Abstract Background Despite the European Society of Cardiology (ESC) guidelines advocating risk prediction models for secondary prevention in established atherosclerotic cardiovascular disease (ASCVD) patients, such models for Japanese individuals remain limited, owing to their comparatively lower ASCVD risk than Western populations. Given this gap, there is a need to develop tailored risk assessment tools for Japanese ASCVD patients to optimize secondary prevention strategies. Purpose Leveraging data from two large-scale, long-term cardiovascular cohorts in Japan, our aim was to develop and externally validate a 10-year risk model predicting recurrent cardiovascular events among patients with established ASCVD. Methods The CHART-2 and Suita studies, large-scale prospective observational multicenter cohort studies in Japan, served as the primary data sources for this investigation. From the CHART-2 study, which comprised 3,560 patients with a history of coronary artery disease or ischemic stroke, we derived our risk model. External validation was conducted using data from the Suita study, which included 445 patients with similar ASCVD backgrounds. The primary outcome of interest was a composite endpoint encompassing cardiovascular death, myocardial infarction, or stroke. Variable selection was performed based on clinically relevant factors previously employed in established risk scores (SMART, REACH, and TRS 2°P risk scores). Logistic regression was utilized for model development, and the predictive performance was assessed using the C-index. Results Over a median follow-up of 10.1 years, the derivation cohort experienced 756 cardiovascular events. Patients in the derivation cohort had an average age of 68.9 ± 10.6 years, with 91% and 24% having a history of coronary artery disease and ischemic stroke, respectively. Using logistic regression, the multivariate model revealed a higher recurrent risk associated with several factors including age, smoking status, systolic blood pressure, diabetes, renal function, number of ASCVD events, atrial fibrillation, lipid levels, left ventricular systolic dysfunction, and statin use. A simple risk score based on these predictors demonstrated a >5-fold gradient of 10-year recurrent risk with a C-index of 0.65 (95% CI 0.63-0.68, Figure). The prediction model was externally validated in the Suita study wit 245 cardiovascular events and a median follow-up of 10.4 years, showing good discriminative ability with a C-index of 0.64 (95% CI 0.60–0.68). Conclusion Our newly developed prediction model offers a valuable tool for identifying individuals at heightened risk of recurrent cardiovascular events over a 10-year period, thereby facilitating more targeted and effective secondary prevention strategies tailored to the unique characteristics of Japanese ASCVD patients.

Cardiovascular related polypharmacy and its association with liver and kidney impairment amongst individuals on lipid-lowering therapy: a cross-sectional study using primary care data

Abstract Background Individuals with risk factors for cardiovascular disease (CVD) frequently require concurrent treatment with various medications, a phenomenon known as polypharmacy. This study aimed to investigate the association between CVD-related polypharmacy and the presence of liver and kidney impairment amongst patients receiving lipid-lowering therapy within the Australian primary care setting. Methods This study utilised electronic medical records from general practices retrieved between January 2013 and December 2023. Multivariate logistic regression identified independent risk factors associated with CVD-related polypharmacy, defined as the concurrent use of five or more CVD protective medications. The analysis included individuals on lipid lowering therapy who are at risk for CVD. The relationship between CVD-related polypharmacy and the presence of liver and kidney dysfunction was further assessed, defined by exceeding established reference ranges for relevant biomarkers (alanine aminotransferase [ALT], aspartate aminotransferase [AST], bilirubin, creatinine, and estimated glomerular filtration rate [eGFR]) as per Australian guidelines. Results A total of 13,568 participants (median age: 63 years [IQR 54-72], 54% males) were included. Independent factors associated with CVD-related polypharmacy included diabetes (OR=5.40, 95% CI: 4.96-5.93), chronic kidney disease (CKD) (OR=2.39, 95% CI: 2.00-2.86), hypertension (OR=1.91, 95% CI: 1.75-2.07), and smoking (OR=1.05, 95% CI: 0.97-1.14). Compared to the 18-35 age group, individuals aged ≥80 years displayed a significantly higher likelihood of CVD-related polypharmacy (OR=8.17, 95% CI: 5.47-12.21). While no significant association was observed between CVD-related polypharmacy and liver impairment (OR=1.19, 95% CI: 0.59-2.37), an independent positive association was identified with kidney impairment (OR=1.38, 95% CI: 1.24-1.54), adjusted for established CVD risk factors including age, sex, smoking, diabetes, hyperlipidaemia, hypertension, and CKD. Conclusion This study suggests a positive association between CVD-related polypharmacy and increased risk of kidney impairment in Australian primary care. Further research is warranted to explore potential causal mechanisms and evaluate the efficacy of medication review strategies, enhanced kidney function monitoring, and potential medication deprescribing in managing patients at risk of CVD who are on multiple medications.

Survodutide for the Treatment of Obesity: Rationale and Design of the SYNCHRONIZE Cardiovascular Outcomes Trial.

Dual agonism of glucagon and glucagon-like peptide-1 (GLP-1) receptors may be more effective than GLP-1 receptor agonism alone in reducing body weight, but the cardiovascular (CV) effects are unknown. The authors describe the rationale and design of SYNCHRONIZE-CVOT, a phase 3, randomized, double-blind, parallel-group, event-driven, CV safety study of survodutide, a dual glucagon and GLP-1 receptor agonist, administered subcutaneously once weekly compared with placebo in adults with a body mass index≥27kg/m2 and established CV disease or chronic kidney disease, and/or at least 2 weight-related complications or risk factors for CV disease. The primary endpoint of SYNCHRONIZE-CVOT is time to first occurrence of the composite adjudicated endpoint of 5-point major adverse CV events. This global CV outcomes trial is currently enrolling, with a target recruitment of 4,935 participants. SYNCHRONIZE-CVOT is the first trial that will determine the CV safety and efficacy of survodutide in people with obesity and increased CV risk.

What is New in the ESC Hypertension Guideline?

Blood pressure guidelines serve as a beacon of best practice for the diagnosis and management of hypertension. The many cultural and societal differences in hypertension risk factors and management patterns across geographic regions support the need for geographically distinct international guidelines. In 2018, the European Society of Cardiology (ESC) and European Society of Hypertension (ESH) released a joint guideline for the management of hypertension.1 This guideline represented a unified front across European hypertension-oriented societies. Similar to preceding hypertension guidelines, the 2018 guideline highlighted the myriad risks associated with inadequate blood pressure management and the importance of improving blood pressure control. The 2018 ESC/ESH guideline also offered a litany of nuanced recommendations on blood pressure measurement and management, including tiered blood pressure diagnosis and management thresholds across various ages and risk factors. For example, the guidelines recommended initiating antihypertensive therapy at a systolic blood pressure threshold of ≥140 mm Hg or a diastolic blood pressure of ≥90 mm Hg in individuals aged 18-79 years, and at a systolic blood pressure threshold of ≥160 mm Hg in individuals aged ≥80 years; treatment initiation could be considered at a blood pressure of ≥130/85 among individuals with established cardiovascular disease. Among individuals being treated for hypertension, the guideline recommended aiming for an initial blood pressure goal of <140/90 mm Hg in all individuals, and if tolerated, further aiming for a systolic blood pressure of 120-129 mm Hg in most individuals aged <65 years and considering a diastolic blood pressure of <80 mm Hg in all individuals. In contrast, contemporary to these guidelines, the 2017 American College of Cardiology/American Heart Association guidelines more broadly recommended stringent blood pressure diagnostic thresholds (≥140/90 mm Hg in lower risk individuals; ≥130/80 mm Hg in higher risk individuals including those with ≥10% 10-year risk of atherosclerotic cardiovascular disease) and management goals (<130/80 mm Hg in all individuals with hypertension). Thus, the 2018 ESC/ESH guideline focused much more on individualized goals. [See the full article for more].

P124 CARDIOVASCULAR RISK RE-CLASSIFICATION BY IMPLEMENTING CAROTID ULTRASONOGRAPHY IN PRIMARY CARE

Background and Objective: The accurate assessment of the total cardiovascular risk (CVR) using risk calculation algorithms in individuals with CVR factors in the primary prevention setting is essential for optimal management decisions, including drug treatment initiation and treatment goals. The aim of this study was to evaluate the contribution of ultrasonographic identification of asymptomatic carotid atherosclerosis in the re-classification of the CVR assessed with the reference SCORE2/2-OP algorithm. Methods: In individuals aged ≥40 years without established cardiovascular disease, the 10-year CVR was calculated using the SCORE2/2-OP algorithm (3 risk categories: low/moderate, high, and very high). Carotid ultrasound study was applied using a portable handheld device (Lumify, Philips) to classify CVR as follows: (i) low/moderate (absence of atherosclerotic plaque), (i) high (atherosclerotic plaque with &lt;50% stenosis), (iii) very high (atherosclerotic plaque with ≥50% stenosis). Results: Data from 332 participants were analysed [age 59±7.5 years, men 41%, current smokers 26%, body mass index 28±5 kg/m2, office blood pressure 125±15/77±10 mmHg (systolic/diastolic), LDL-cholesterol 111±33 mg/dl]. Based on SCORE2/2-OP, 49/46/5% participants were categorised as of low/moderate, high, and very high CVR, respectively. Based on carotid ultrasound, the rates were 39/59/2%, respectively. 44% of individuals categorized as of low/moderate CVR based on SCORE2/2-OP were re-classified into a higher CVR category based on carotid ultrasound. The agreement between the 2 methods (ultrasound versus algorithms) in categorizing low/moderate and high CVR was 67% (kappa 0.35, P&lt;0.001) and 61% (kappa 0.23, P&lt;0.001), respectively. Among 204 participants categorized as of high/very high CVR according to carotid ultrasound, only 15 (7%) had LDL-cholesterol levels &lt;70 mg/dl. Conclusions: These findings suggest that carotid ultrasonography using a portable handheld device may significantly contribute to assess CVR more accurately in primary care, especially in individuals classified as of low/moderate CVR using reference algorithms.

Association of Preserved Ratio Impaired Spirometry with Arterial Stiffness.

Rationale: Preserved ratio impaired spirometry (PRISm) is a recently recognized spirometric pattern defined by a ratio of forced expiratory volume in 1 second to forced vital capacity of at least 0.70 and a forced expiratory volume in 1 second <80% of reference. For unclear reasons, PRISm is associated with increased cardiovascular (CV) morbidity and mortality. Arterial stiffness is a major mechanism of CV disease, which can be measured by carotid-femoral pulse-wave velocity (cfPWV). Objectives: We explored the hypothesis that cfPWV would be increased in individuals with PRISm and airflow limitation (AL). Methods: We measured forced spirometry, lung volumes by body plethysmography, and cfPWV in 9,466 subjects recruited from the general population in the Austrian cross-sectional LEAD (Lung, Heart, Social, Body) study and tested the association of arterial stiffness with PRISm and AL by multivariable linear regression analysis. Individuals younger than 18 years were excluded from the study. Results: Individuals with PRISm (n = 431; 4.6%) were of similar age to those with normal spirometry (n = 8,136; 85.9%) and significantly younger than those with AL (n = 899; 9.5%). Arterial hypertension, diabetes mellitus, coronary artery disease, heart failure, and peripheral arterial occlusive disease were significantly more common in individuals with PRISm than in those with normal lung function and similar to those with AL. There was a significant association between PRISm and arterial stiffness on bivariate linear regression analysis (crude model, β = 0.038; 95% confidence interval [CI], 0.016-0.058), which persisted after robust adjustment for clinical confounders upon multivariable analysis (final model, β = 0.017; 95% CI, 0.001-0.032). cfPWV was significantly higher in individuals with PRISm irrespective of the presence of established CV disease or pulmonary restriction. AL also showed a significant association with arterial stiffness on multivariable linear regression analysis (final model, β = 0.025; 95% CI, 0.009-0.042). Conclusions: Arterial stiffness measured by cfPWV is increased in individuals with PRISm independent of CV disease and risk factors. The pathobiological mechanisms underlying this association deserve further research.

The Effect of Semaglutide on Mortality and COVID-19–Related Deaths: An Analysis From the SELECT Trial

BackgroundPatients with overweight and obesity are at increased risk of death from multiple causes, including cardiovascular (CV) death, with few therapies proven to reduce the risk. ObjectivesThis study sought to assess the effect of semaglutide 2.4 mg on all-cause death, CV death, and non-CV death, including subcategories of death and death from coronavirus disease-2019 (COVID-19). MethodsThe SELECT (Semaglutide Effects on Cardiovascular Outcomes in Patients With Overweight or Obesity) trial randomized 17,604 participants ≥45 years of age with a body mass index ≥27 kg/m2 with established CV disease but without diabetes to once-weekly subcutaneous semaglutide 2.4 mg or placebo; the mean trial duration was 3.3 years. Adjudicated causes of all deaths, COVID-19 cases, and associated deaths were captured prospectively. ResultsOf 833 deaths, 485 (58%) were CV deaths, and 348 (42%) were non-CV deaths. Participants assigned to semaglutide vs placebo had lower rates of all-cause death (HR: 0.81; 95% CI: 0.71-0.93), CV death (HR: 0.85; 95% CI: 0.71-1.01), and non-CV death (HR: 0.77; 95% CI: 0.62-0.95). The most common causes of CV death with semaglutide vs placebo were sudden cardiac death (98 vs 109; HR: 0.89; 95% CI: 0.68-1.17) and undetermined death (77 vs 90; HR: 0.85; 95% CI: 0.63-1.15). Infection was the most common cause of non-CV death and occurred at a lower rate in the semaglutide vs the placebo group (62 vs 87; HR: 0.71; 95% CI: 0.51-0.98). Semaglutide did not reduce incident COVID-19; however, among participants who developed COVID-19, fewer participants treated with semaglutide had COVID-19–related serious adverse events (232 vs 277; P = 0.04) or died of COVID-19 (43 vs 65; HR: 0.66; 95% CI: 0.44-0.96). High rates of infectious deaths occurred during the COVID-19 pandemic, with less infectious death in the semaglutide arm, and resulted in fewer participants in the placebo group being at risk for CV death. ConclusionsCompared to placebo, patients treated with semaglutide 2.4 mg had lower rates of all-cause death, driven similarly by CV and non-CV death. The lower rate of non-CV death with semaglutide was predominantly because of fewer infectious deaths. These findings highlight the effect of semaglutide on mortality across a broad population of patients with CV disease and obesity.

Identification of Novel Independent Correlations between Cellular Components of the Immune System and Strain-Related Indices of Myocardial Dysfunction in CKD Patients and Kidney Transplant Recipients without Established Cardiovascular Disease.

The role of immune system components in the development of myocardial remodeling in chronic kidney disease (CKD) and kidney transplantation remains an open question. Our aim was to investigate the associations between immune cell subpopulations in the circulation of CKD patients and kidney transplant recipients (KTRs) with subclinical indices of myocardial performance. We enrolled 44 CKD patients and 38 KTRs without established cardiovascular disease. A selected panel of immune cells was measured by flow cytometry. Classical and novel strain-related indices of ventricular function were measured by speckle-tracking echocardiography at baseline and following dipyridamole infusion. In CKD patients, the left ventricular (LV) relative wall thickness correlated with the CD14++CD16- monocytes (β = 0.447, p = 0.004), while the CD14++CD16+ monocytes were independent correlates of the global radial strain (β = 0.351, p = 0.04). In KTRs, dipyridamole induced changes in global longitudinal strain correlated with CD14++CD16+ monocytes (β = 0.423, p = 0.009) and CD4+ T-cells (β = 0.403, p = 0.01). LV twist and untwist were independently correlated with the CD8+ T-cells (β = 0.405, p = 0.02 and β = -0.367, p = 0.03, respectively) in CKD patients, whereas the CD14++CD16+ monocytes were independent correlates of LV twist and untwist in KTRs (β = 0.405, p = 0.02 and β = -0.367, p = 0.03, respectively). Immune cell subsets independently correlate with left ventricular strain and torsion-related indices in CKD patients and KTRs without established CVD.

The effectiveness of the Mediterranean Diet for primary and secondary prevention of cardiovascular disease: An umbrella review.

This study aimed to review meta-analyses of randomised controlled trials that evaluated the effectiveness of the Mediterranean Diet for the primary and secondary prevention of cardiovascular disease. Five databases (Medline, Embase, Cochrane, CINAHL and ProQuest) were searched from inception to November 2022. Inclusion criteria were: (i) systematic review of randomised controlled studies with metanalysis; (ii) adults ≥18 years from the general population with (secondary prevention) and without (primary prevention) established cardiovascular disease; (iii) Mediterranean Diet compared with another dietary intervention or usual care. Review selection and quality assessment using AMSTAR-2 were completed in duplicate. GRADE was extracted from each review, and results were synthesised narratively. Eighteen meta-analyses of 238 randomised controlled trials were included, with an 8% overlap of primary studies. Compared to usual care, the Mediterranean Diet was associated with reduced cardiovascular disease mortality (n = 4 reviews, GRADE low certainty; risk ratio range: 0.35 [95% confidence interval: 0.15-0.82] to 0.90 [95% confidence interval: 0.72-1.11]). Non-fatal myocardial infarctions were reduced (n = 4 reviews, risk ratio range: 0.47 [95% confidence interval: 0.28-0.79] to 0.60 [95% confidence interval: 0.44-0.82]) when compared with another active intervention. The methodological quality of most reviews (n = 16/18; 84%) was low or critically low and strength of evidence was generally weak. This review showed that the Mediterranean Diet can reduce fatal cardiovascular disease outcome risk by 10%-67% and non-fatal cardiovascular disease outcome risk by 21%-70%. This preventive effect was more significant in studies that included populations with established cardiovascular disease. Better quality reviews are needed.

Lipid Control and Medical Costs Among Patients With and Without Established Atherosclerotic Cardiovascular Disease Followed in a Brazilian Private Healthcare System.

There is limited real-world data of lipid control and healthcare costs among patients with and without Atherosclerotic Cardiovascular Disease (ASCVD) in Latin America. A retrospective cohort study including patients with LDL-cholesterol (LDL-C) assessment from 2015 to 2017 was performed in a health insurance database. Patient characteristics, comorbidities and laboratory data were collected, and International Classification of Diseases (ICD) codes were used to identify a subcohort of patients with ASCVD (secondary prevention) and assess the proportion of these patients with LDL-C controlled. Lipid control among patients without ASCVD (primary prevention) and healthcare costs in one year in the overall population were also assessed. From the 17,434 patients selected, 5,208 (29.8%) had ASCVD. The mean age of these patients in secondary prevention was 68.9 (±12.3) years and 47.8% were male patients. LDL-C < 70 mg/dL was identified in 19.1% of the ASCVD population and only 4.1% had an LDL-C < 50 mg/dL. LDL control was worse in women compared to men (13.1% vs. 25.7%; P < 0.01). The average cost in one year was 3,591 American dollars (USD) per patient in primary prevention compared to 8,210 dollars per year for patients in secondary prevention (P < 0.01). While outpatient costs accounted for 59.8% of the total cost in the primary prevention group, the main cost of the secondary prevention population was related to hospital costs (54.1%). Despite the favorable evidence for intensive cholesterol reduction, the evaluation of large real-world database with more than 17,000 individuals showed that the targets of guideline recommendations have not yet been adequately incorporated into clinical practice. Average annual cost per patient in secondary prevention is more than twice compared to primary prevention. Hospital expenses account for most of the cost in the secondary prevention group, while outpatient costs predominate in primary prevention.

Cardiology patients are unaware of the benefits of seasonal influenza immunization

Seasonal influenza immunization reduces the risk of cardiovascular events. Patients with established cardiovascular disease (CVD) derive a greater benefit than those without, yet up to 50 % do not take up the immunization. Patient perceptions and beliefs are known to inform immunization behaviors, yet the immunization related beliefs of patients with CVD have not been described. ObjectiveTo describe beliefs, perceptions and behaviors regarding influenza immunization in patients with CVD. MethodsWe undertook a cross-sectional, voluntary and anonymous survey of 181 cardiology inpatients and outpatients attending three large hospitals in Victoria. ResultsMedian age was 64, 35.0 % were female and 24.2 % spoke a language other than English at home. Over one-third-(34.5 %) of respondents did not receive the seasonal influenza immunization in the prior year. Only half (54.2 %) of patients agreed that their heart condition placed them at higher risk of complications and serious illness if they contracted influenza. Nearly a quarter of patients (24.0 %) were concerned about side effects while 1 in 10 patients raised cost as a barrier despite being free-of-charge in Australia. If asked to receive the seasonal influenza immunization, 86 % patients would agree if their cardiologist recommended it. ConclusionDespite guideline recommendations, most cardiology patients are uninformed of the cardiovascular benefits of seasonal influenza immunization with many unaware they are at higher risk of influenza-related illness. The vast majority of patients would accept the immunization if recommended by their cardiologist highlighting their important role in improving uptake.

Marital Quality-A Neglected Player in the Prevention of Cardiovascular Diseases: A Systematic Review of Longitudinal Studies.

Marital quality (MQ) is a psychosocial factor that has been neglected in cardiovascular prevention guidelines, although its association with cardiovascular diseases has been identified in several studies. Therefore, we aim to investigate how MQ either in positive or negative dimensions affect different cardiovascular risk factors and diseases. We systematically searched different databases in September 2023 for longitudinal studies conducted to assess the contribution of MQ to well-established cardiovascular risk factors and diseases. Two independent researchers screened studies and carried out data extraction and quality assessment of included ones. From 12,175 potential studies screened, 40 were included. The presence of significant heterogeneity in methodology, follow-up, and subsequent effect estimates made it unfeasible to do a meta-analysis. Despite the variation, most studies found a significant association of negative MQ measures with physical inactivity (2/2), high levels of smoking (4/5) and alcohol (3/3) use, increased metabolic syndrome risk (3/3), elevated type 2 diabetes mellitus (T2DM) risk and poor T2DM management (3/6), elevated cardiovascular disease risk and progression (9/11), increased body weight and obesity risk (2/3), elevated blood pressure and hypertension risk (7/8). Positive MQ measures were mainly associated with improvement in blood pressure control (2/2), reduced T2DM risk and its good management (1/1), reduced body weight and obesity risk (2/2), and increased survival in cardiovascular diseases (4/4). Based on current evidence, MQ seems to play a crucial role in developing established cardiovascular risk factors and diseases and is worth considering in preventive strategies.

Barriers and Strategies to Optimize the Use of Glucagon-Like Peptide 1 Receptor Agonists in People with Type 2 Diabetes and High Cardiovascular Risk or Established Cardiovascular Disease: A Delphi Consensus in Spain.

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are effective for glycemic control, with many also demonstrating cardiovascular (CV) benefit, in people with type 2 diabetes (T2D). This study aimed to find a consensus on the barriers and strategies for the optimal use of GLP-1 RAs in people with T2D and high CV risk or established cardiovascular disease (CVD) in Spain. A two-round Delphi survey (53 questions) was conducted among members of four national scientific societies in Spain, including physicians experienced in the management of people with T2D. The degree of consensus was evaluated with a 7-point Likert scale, establishing consensus when≥70% of the panelists agreed (6-7) or disagreed (1-2). A total of 97 physicians participated in the first round (endocrinology: 34%, family and community medicine: 21%, internal medicine: 23%, and cardiology: 23%), and 96 in the second round. The main barriers identified were: therapeutic inertia and late use of GLP-1 RAs; lack of a comprehensive approach to CV risk; lack of knowledge on the usefulness of GLP-1 RAs in CVD prevention and treatment; and economic/administrative barriers. Strategies with a highest consensus included: the need to establish simple protocols that integrate awareness of CV risk monitoring; training professionals and patients; and the use of new technologies. Physicians identified clinical, healthcare, and economic/administrative barriers that limit the use of GLP-1 RAs in people with T2D and high CV risk or established CVD in Spain, highlighting the importance of integrating these therapies according to clinical practice guidelines.
