Aim: Arterial stiffness hallmarks age-related cardiovascular diseases, precedes their onset and strongly links to accelerated disease progression. However, whether carotid-to-femoral pulse wave velocity (PWV), a proxy of arterial stiffness, predicts cardiovascular risk over and above SCORE2, a newly introduced risk score remains to be investigated., Methods: We measured PWV among 747 individuals without established atheromatosis. Study participants were followed up over a 6-year period for the incidence of cardiovascular events [[MACE)-cardiovascular mortality, stroke and myocardial infarction]., Results: PWV emerged as an independent and additive predictor of first cardiovascular events when added in a model encompassing SCORE2 (hazard ratio = 1.10; 95% confidence interval (95% CI) = 1.07-1.14; P < 0.001, Brier score changed from 0.073 (0.060-0.086) to 0.067 (0.055-0.081); P < 0.001, c-statistic increased from 0.71 to 0.75; P = 0.017; likelihood ratio: 20.22; P < 0.001; the overall net reclassification improvement (NRI): 0.577; P < 0.001, AICc changed from 697.81 to 679.60; BIC changed from 702.42 to 688.82]. An increase in PWV predicted a greater risk of future MACEs additively to conventional risk factors (P < 0.05). We performed Kaplan-Meier survival analysis for the tertiles of PWV [first tertile < 8.04 m/s; the second tertile: (8.04-10 m/s); the third tertile: (10-17.10 m/s); (P < 0.05 for all comparisons between the tertiles). PWV tertiles also predicted MACE when added to SCORE2 [for the second tertile: hazard ratio: 5.87 (95% CI: 1.73-19.92); P = 0.004 and for the third tertile: hazard ratio: 9.69 (95% CI: 2.97-31.55); P < 0.001 with the respective change of c-statistic from 0.739 to 0.772; P = 0.012 and continuous NRI = 0.598]., Conclusion: PWV confers additive prognostic value to the newly introduced SCORE2 for adverse outcome in primary prevention., (Copyright © 2024 Wolters Kluwer Health, Inc.

Aims: Non-alcoholic fatty liver disease (NAFLD) with advanced liver fibrosis is associated with cardiovascular disease (CVD). To examine if markers of vascular injury mediate the link between liver fibrosis non-invasive tests (LFNITs) and CVD events, and to compare the incremental predictive value of LFNITs over established CVD risk scores., Methods: Consecutively recruited individuals (n=1,692) with or without clinically overt coronary artery disease (CAD) from the Athens Cardiometabolic Cohort, were analysed. Fibrosis-4 index (FIB-4), NAFLD Fibrosis score (NFS), and BARD score were evaluated for direct and indirect associations with indices of subclinical arterial injury including carotid maximal wall thickness (maxWT) and pulse wave velocity (PWV) and with a composite of major adverse cardiovascular events (MACE) that consisted of cardiac death, acute myocardial infarction, or coronary revascularization (39-month median follow-up)., Results: FIB-4 was the only LFNIT which consistently associated with multiple markers of vascular injury, irrespective of CAD presence and after controlling for traditional risk factors, surrogates of insulin resistance or obesity (adjusted p<0.05 for all). FIB-4 also independently associated with CAD presence (adjusted OR 6.55 (3.48-12.3), p<0.001). Increased FIB-4>2.67 was incrementally associated with increased risk for MACE (OR (95% CI) 2.00(1.12, 3.55), deltaAUC (95% CI) 0.014(0.002-0.026)). These associations were mediated by maxWT rather than PWV. Only FIB-4 (>3.25) was independently and incrementally associated with all-cause mortality (adjusted p<0.05)., Conclusions: In a cardio-metabolically diverse population, the incremental associations of LFNITs with CVD outcomes were mediated by atherosclerotic burden rather than arterial stiffening. FIB-4 consistently demonstrated associations with all study endpoints. These findings provide mechanistic insights and support the clinical applicability of FIB-4 in CVD prevention., (© The Author(s) 2024.

Background: Clinical characteristics and outcomes of patients with transthyretin amyloidosis cardiomyopathy (ATTR-CM) vary by region, necessitating the acquisition of country-specific evidence for proper management., Methods: This is an observational study including sequential patients presenting in the Amyloidosis Reference Center of Greece, from 01/2014 to 12/2022. ATTR-CM was diagnosed by positive scintigraphy and exclusion of light-chain amyloidosis or positive biopsy typing. Genetic testing was performed in all cases., Results: In total, 109 ATTR-CM patients were included (median age, 81 years) of which 15 carried TTR mutations (27% Val30Met). Most patients (82%) presented with heart failure and 59% with atrial fibrillation, while 10% had aortic stenosis. Importantly, 78 (71.6%) had clinically significant extracardiac manifestations (45% musculoskeletal disorder, 40% peripheral neuropathy, and 33% gastrointestinal symptoms). Sixty-five (60%) received disease-specific treatment with tafamidis. Estimated median survival was 48 months; advanced NYHA class, National Amyloidosis Center stage, eGFR<45 ml/kg/1.73 m 2 , NT-pro-BNP>5000 pg/mL were associated with worse survival, while tafamidis treatment was associated with improved survival in patients with IVS≥ 12 mm., Discussion: These are the first data describing the characteristics, management, and outcomes of patients with ATTR-CM in Greece, which could influence local guidelines., Competing Interests: Declaration of competing interest GG has received research support from Pfizer.

Circulating amyloid-beta 1-40 (Αb40) has pro-atherogenic properties and could serve as a biomarker in atherosclerotic cardiovascular disease (ASCVD). However, the association of Ab40 levels with morphological characteristics reflecting atherosclerotic plaque echolucency and composition is not available. Carotid atherosclerosis was assessed in consecutively recruited individuals without ASCVD (n = 342) by ultrasonography. The primary endpoint was grey scale median (GSM) of intima-media complex (IMC) and plaques, analysed using dedicated software. Vascular markers were assessed at two time-points (median follow-up 35.5 months). In n = 56 patients undergoing carotid endarterectomy, histological plaque features were analysed. Plasma Αb40 levels were measured at baseline. Ab40 was associated with lower IMC GSM and plaque GSM and higher plaque area at baseline after multivariable adjustment. Increased Ab40 levels were also longitudinally associated with decreasing or persistently low IMC and plaque GSM after multivariable adjustment (p < 0.05). In the histological analysis, Ab40 levels were associated with lower incidence of calcified plaques and plaques without high-risk features. Ab40 levels are associated with ultrasonographic and histological markers of carotid wall composition both in the non-stenotic arterial wall and in severely stenotic plaques. These findings support experimental evidence linking Ab40 with plaque vulnerability, possibly mediating its established association with major adverse cardiovascular events., (© 2024.

Background: In this study we used Mendelian randomization (MR) to investigate the potential causal association of lipoprotein (a) [Lp(a)] levels with pulse wave velocity (PWV)., Methods: Genetic variants associated with Lp(a) were retrieved from the UK Biobank GWAS (N = 290,497). A non- overlapping GWAS based on a European cohort (N = 7,000) was used to obtain genetic associations with PWV (outcome) and utilized two different measures for the same trait, brachial-ankle (baPWV) and carotid-femoral (cfPWV) PWV. We applied a two-sample MR using the inverse variance weighting method (IVW) and a series of sensitivity analyses for 170 SNPs that were selected as instrumental variables (IVs)., Results: Our analyses do not support a causal association between Lp(a) and PWV for neither measurement [β iwv (baPWV) = -.0005, p = .8 and β iwv (cfPWV) = -.006, p = .16]. The above findings were consistent across sensitivity analyses including weighted median, mode-based estimation, MR-Egger regression and MR-PRESSO., Conclusion: We did not find evidence indicating that Lp(a) is causally associated with PWV, the gold standard marker of arterial stiffness., (© 2024 Stichting European Society for Clinical Investigation Journal Foundation.

This study examined the effects of orange juice (OJ) supplemented with vitamin D3 (2000 IU) and probiotics ( Lacticaseibacillus casei Shirota and Lacticaseibacillus rhamnosus GG, 10 8 cfu/mL) on cardiometabolic risk factors in overweight and obese adults following a Westernized-type diet. Fifty-three high-risk individuals were randomly assigned to one of two groups. Over 8 weeks, one group consumed a vitamin D3 and probiotic-enriched OJ and the other regular OJ (control). Diets remained unchanged and were documented through food diaries. Measures of metabolic and inflammatory markers and blood pressure were measured at the start and end of the study. Post-intervention, the enriched OJ group showed the following significant metabolic improvements (without changes in triglycerides, inflammation, or central blood pressure): reduced fasting insulin, peripheral blood pressure, body weight (-1.4 kg 95% CI: -2.4, -0.4), energy (-270 kcal 95% CI: -553.2, -13.7), macronutrient (dietary fat -238 kcal 95% CI: -11.9, -1.0; carbohydrates -155 kcal 95% CI: -282.4, -27.3; sugars -16.1 g 95% CI: -11.9, -1.0) intake, and better lipid profiles (total cholesterol -10.3 mg/dL 95% CI: -21.4, 0.9; LDL-C -7 mg/dL 95% CI: -13.5, -0.5). The enriched OJ led to weight loss, less energy/macronutrient consumption, improved lipid profiles, and increased insulin sensitivity after 8 weeks in those following a Westernized diet, thus indicating potential benefits for cardiometabolic risk. This study was a part of FunJuice-T2EDK-01922, which was funded by the EU Regional Development Fund and Greek National Resources.

Background: Female sexual dysfunction (FSD) has been suggested to be correlated with the burden of cardiovascular risk factors., Aim: We aimed to evaluate the possible association between functional indices of vascular function and FSD scores in apparently healthy postmenopausal women., Methods: This cross-sectional study included 116 postmenopausal women who underwent assessment of endothelial function with measurement of flow-mediated dilation (FMD) of the branchial artery and arterial stiffness estimation with measurement of the carotid-femoral pulse wave velocity (PWV). We used the Greene Climacteric Scale to evaluate vasomotor symptomatology, the Female Sexual Function Index (FSFI) to evaluate FSD and the Beck Depression Inventory to evaluate mood disorder. Low sexual function was defined as an FSFI score <26.55., Outcomes: These included FSFI and low sexual function scores as well as measures of PWV and FMD., Results: Sexual function scores were associated with measures of blood pressure (normal vs low sexual function; systolic blood pressure: 120.2 ± 15.0 mm Hg vs 113.4 ± 14.6 mm Hg; analysis of covariance P = .026; diastolic blood pressure: 75.9 ± 10.5 mm Hg vs 70.3 ± 9.9 mm Hg; analysis of covariance P = .012; both adjusted for age, body mass index, current smoking, and PWV). Systolic blood pressure, but not diastolic blood pressure, was associated with FSFI (B = 0.249, P = .041) and PWV (B = 0.392, P < .001). PWV measures were associated with FSFI (B = -0.291, P = .047) and pulse pressure (B = 0.355, P = .017). FMD measures were also associated with FSFI (B = 0.427, P = .033). All models were adjusted for age, body mass index, current smoking, insulin resistance, vasomotor symptomatology, and Beck Depression Inventory., Clinical Implications: Our findings demonstrate that lower scores of sexual function are associated with deteriorated vascular function mainly manifested as arterial stiffening, further contributing to systolic blood pressure changes., Strengths and Limitations: The strength of this study is the carefully selected healthy sample of postmenopausal women, with simultaneous assessment of climacteric symptomatology and mood disorders. The limitations include the small sample size, the cross-sectional design, and the recruitment of consecutive outpatients of a university menopause clinic., Conclusion: Longitudinal studies and interventions to improve FSD should further assess the clinical relevance of these findings., (© The Author(s) 2023.

Background: Accumulating evidence suggests a substantial contribution of remnant cholesterol (RC) to residual risk for the development or relapse of atherosclerotic cardiovascular disease (ASCVD). We aimed to evaluate the association of RC levels with ASCVD risk by different risk categories and methods of RC assessment. We also assessed available evidence of the effects of lipid-lowering therapies (LLTs) on RC levels., Methods: English-language searches of Medline, PubMed, and Embase (inception to 31 January 2023); ClinicalTrials.gov (October 2022); and reference lists of studies and reviews. Studies reporting on the risk of the composite endpoint [all-cause mortality, cardiovascular mortality, and major adverse cardiac events (MACE)] by RC levels were included. Moreover, we searched for studies reporting differences in RC levels after the administration of LLT(s)., Results: Among n = 29 studies with 257,387 participants, we found a pooled linear (pooled HR: 1.27 per 1-SD increase, 95% CI: 1.12-1.43, P < 0.001, I 2  = 95%, n = 15 studies) and non-linear association (pooled HR: 1.59 per quartile increase, 95% CI: 1.35-1.85, P < 0.001, I 2  = 87.9%, n = 15 studies) of RC levels and the risk of M ACE both in patients with and without established ASCVD. Interestingly, the risk of MACE was higher in studies with directly measured vs. calculated RC levels. In a limited number of studies and participants, LLTs reduced RC levels., Conclusion: RC levels are associated with ASCVD risk both in primary and secondary prevention. Directly measured RC levels are associated with ASCVD risk more evidently. Available LLTs tend to decrease RC levels, although the clinical relevance of RC decrease merits further investigation., Prospero Registration: CRD42022371346., (Copyright © 2023 Hellenic Society of Cardiology.

Importance: The Global Registry of Acute Coronary Events (GRACE) risk score, a guideline-recommended risk stratification tool for patients presenting with acute coronary syndromes (ACS), does not consider the extent of myocardial injury., Objective: To assess the incremental predictive value of a modified GRACE score incorporating high-sensitivity cardiac troponin (hs-cTn) T at presentation, a surrogate of the extent of myocardial injury., Design, Setting, and Participants: This retrospectively designed longitudinal cohort study examined 3 independent cohorts of 9803 patients with ACS enrolled from September 2009 to December 2017; 2 ACS derivation cohorts (Heidelberg ACS cohort and Newcastle STEMI cohort) and an ACS validation cohort (SPUM-ACS study). The Heidelberg ACS cohort included 2535 and the SPUM-ACS study 4288 consecutive patients presenting with a working diagnosis of ACS. The Newcastle STEMI cohort included 2980 consecutive patients with ST-elevation myocardial infarction treated with primary percutaneous coronary intervention. Data were analyzed from March to June 2023., Exposures: In-hospital, 30-day, and 1-year mortality risk estimates derived from an updated risk score that incorporates continuous hs-cTn T at presentation (modified GRACE)., Main Outcomes and Measures: The predictive value of continuous hs-cTn T and modified GRACE risk score compared with the original GRACE risk score. Study end points were all-cause mortality during hospitalization and at 30 days and 1 year after the index event., Results: Of 9450 included patients, 7313 (77.4%) were male, and the mean (SD) age at presentation was 64.2 (12.6) years. Using continuous rather than binary hs-cTn T conferred improved discrimination and reclassification compared with the original GRACE score (in-hospital mortality: area under the receiver operating characteristic curve [AUC], 0.835 vs 0.741; continuous net reclassification improvement [NRI], 0.208; 30-day mortality: AUC, 0.828 vs 0.740; NRI, 0.312; 1-year mortality: AUC, 0.785 vs 0.778; NRI, 0.078) in the derivation cohort. These findings were confirmed in the validation cohort. In the pooled population of 9450 patients, modified GRACE risk score showed superior performance compared with the original GRACE risk score in terms of reclassification and discrimination for in-hospital mortality end point (AUC, 0.878 vs 0.780; NRI, 0.097), 30-day mortality end point (AUC, 0.858 vs 0.771; NRI, 0.08), and 1-year mortality end point (AUC, 0.813 vs 0.797; NRI, 0.056)., Conclusions and Relevance: In this study, using continuous rather than binary hs-cTn T at presentation, a proxy of the extent of myocardial injury, in the GRACE risk score improved the mortality risk prediction in patients with ACS.

Objective: Sex-specific data are limited regarding eligibility for hypolipidemic treatment. We aim to explore the sex-specific clinical utility of high-sensitivity C-reactive protein (hsCRP) and carotid ultrasound as risk modifiers for hypolipidemic treatment in primary prevention of atherosclerotic cardiovascular disease (ASCVD)., Methods: We aimed to explore these sex-specific trends in two pooled contemporary independent Greek cohorts (Athens Vascular Registry n = 698, 50.9% women and Menopause Clinic n = 373, 100% women) of individuals without overt ASCVD. Baseline ASCVD risk was estimated using the Systematic COronary Risk Evaluation-2 (SCORE2) tools. The presence of carotid plaque and hsCRP ≥2 mg/L were integrated as risk modifiers., Results: Men had increased odds to achieve target LDL-C levels based on ASCVD risk (23.8% vs. 17.7%, OR: 1.45 95% CI: 1.05-2.00, p = 0.023, for men vs. women). Additionally, considering carotid plaque or high hsCRP levels did not change this association but reduced on-target LDL-C rate in both sexes. Women had decreased odds of being eligible for hypolipidemic treatment by ASCVD risk estimation (11.5% vs. 26.4%, p < 0.001) compared with men. The addition of carotid plaque presence or high hsCRP levels and their combination resulted in a higher relative increase in hypolipidemic treatment eligibility in women (from 11.5% to 70.9% vs. 26.4% to 61.4% for carotid plaque, from 11.5% to 38.5% vs. 26.4% to 50.8% for hsCRP and from 11.5% to 79.1% vs. 26.4% to 75% for their combination, all for women vs. men, p for interaction < 0.001 for all) than men., Conclusions: Implementation of carotid plaque and hsCRP levels increases hypolipidemic treatment eligibility more prominently in women than in men. The impact on clinical outcomes in these untreated patients merits further investigation., (Copyright © 2023 Hellenic Society of Cardiology. Published by Elsevier B.V. All rights reserved.)

The causative associations between glycemia and early alterations in renal and vascular function remain unclear. To examine the interplay among glycemia, renal function, and markers of subclinical atherosclerosis in apparently healthy subjects. Nondiabetic (30-60 years old) individuals (n = 205) without chronic kidney disease or cardiovascular disease were consecutively recruited from a cardiovascular prevention clinic. All subjects underwent arterial stiffness assessment by measuring the carotid-femoral pulse wave velocity (cfPWV). Glomerular filtration rate (GFR) was estimated by CKD-EPI equation. Study procedures were identical in the two visits (median follow-up 66 months). We employed structural equation modeling (SEM) analysis to investigate the directionality of associations. Baseline fasting plasma glucose (FPG) was independently and inversely associated with GFR (p = 0.008). GFR was significantly associated with cfPWV (p < 0.001) at baseline. By SEM analysis decreasing baseline GFR directly correlated with increasing cfPWV (p = 0.003) whereas FPG correlated with cfPWV indirectly through GFR (mediation) (P = 0.032). FPG did not mediate the effect of GFR on cfPWV (P = 0.768). SEM analysis of longitudinal data revealed bidirectional correlations between changes in FPG and GFR (P < 0.001). Alterations in GFR were directly related to changes in cfPWV (p < 0.001) whereas FPG only indirectly correlated with cfPWV through GFR changes (P = 0.002). In apparently healthy nondiabetic subjects, the association between baseline or longitudinal glycemia levels and arterial stiffening was indirect, consistently mediated by renal function status. These findings provide the first clinical evidence supporting the directionality between kidney function and glycemia in nondiabetic subjects leading to vascular dysfunction. In apparently healthy nondiabetic subjects, without cardiovascular disease or chronic kidney disease, the association between baseline or longitudinal glycemia levels and arterial stiffening was indirect, consistently mediated by renal function status., (© 2023.

Proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) represent a novel class of hypolipidemic drugs, providing an additional therapeutic option over conventional hypolipidemic treatments. Given the constantly lowering recommended LDL-C goals, low goal achievement rate and low compliance with treatment, new hypolipidemic drug classes may substantially contribute to residual risk reduction for atherosclerotic cardiovascular disease (ASCVD). This review aims to summarize contemporary evidence on the clinical role of PCSK9i in ASCVD prevention. PubMed and MEDLINE databases were searched for keywords in studies on PCSK9i and ASCVD. Approved PCSK9i are the monoclonal antibodies (Mabs), evolocumab and alirocumab, targeting PCSK9, and inclisiran, a small interfering RNA inhibiting PSCK9 synthesis. Overall, PCSK9i effectively reduced LDL-C and other atherogenic lipoproteins, including apolipoprotein B and lipoprotein( a) primarily. PSCK9i Mabs improved imaging markers reflecting coronary atherosclerotic plaque vulnerability and reduced ASCVD events in high-risk patients after short-term treatment (< 3 years follow-up). They are currently indicated as a third-line treatment for secondary prevention and primary prevention in patients with familial hypercholesterolemia at high risk of not achieving their LDL-C goals. Patients with higher baseline ASCVD risk receive greater benefits from PCSK9i. Recent evidence suggests that evolocumab was effective and safe after long-term treatment. Ongoing trials investigate new therapeutic indications for PCSK9i while their cost-effectiveness is still being considered. PCSK9i is a novel hypolipidemic drug class currently indicated for reducing residual risk in secondary ASCVD prevention and high-risk patients., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Background: Accumulating evidence suggests that endothelial dysfunction is implicated in the pathogenesis and severity of coronavirus disease 2019 (COVID-19). In this context, vascular impairment in COVID-19 might be associated with clinical manifestations and could refine risk stratification in these patients., Methods: This systematic review aims to synthesize current evidence on the frequency and the prognostic value of vascular dysfunction during acute and post-recovery COVID-19. After systematically searching the MEDLINE, clinicaltrials.gov and the Cochrane Library from 1 December 2019 until 05 March 2022, we identified 24 eligible studies with laboratory confirmed COVID-19 and a thorough examination of vascular function. Flow-mediated dilation (FMD) was assessed in 5 and 12 studies in acute and post-recovery phase respectively; pulse wave velocity (PWV) was the marker of interest in three studies in the acute and four studies in the post-recovery phase., Results: All studies except for one in the acute and in the post-recovery phase showed positive association between vascular dysfunction and COVID-19 infection. Endothelial dysfunction in two studies and increased arterial stiffness in three studies were related to inferior survival in COVID-19., Discussion: Overall, a detrimental effect of COVID-19 on markers of endothelial function and arterial stiffness that could persist even for months after the resolution of the infection and provide prognostic value was congruent across published studies. Further research is warranted to elucidate clinical implications of this association., (© 2022 Stichting European Society for Clinical Investigation Journal Foundation.

Background:  The noncoding antisense transcript for β-secretase-1 ( BACE1-AS ) is a long noncoding RNA with a pivotal role in the regulation of amyloid-β (Aβ). We aimed to explore the clinical value of BACE1-AS expression in atherosclerotic cardiovascular disease (ASCVD)., Methods:  Expression of BACE1-AS and its target, β-secretase 1 ( BACE1 ) mRNA, was measured in peripheral blood mononuclear cells derived from 434 individuals (259 without established ASCVD [non-CVD], 90 with stable coronary artery disease [CAD], and 85 with acute coronary syndrome). Intima-media thickness and atheromatous plaques evaluated by ultrasonography, as well as arterial wave reflections and pulse wave velocity, were measured as markers of subclinical ASCVD. Patients were followed for a median of 52 months for major adverse cardiovascular events (MACE)., Results:  In the cross-sectional arm, BACE1-AS expression correlated with BACE1 expression ( r  = 0.396, p  < 0.001) and marginally with Aβ1-40 levels in plasma ( r  = 0.141, p  = 0.008). Higher BACE1-AS was associated with higher estimated CVD risk assessed by HeartScore for non-CVD subjects and by European Society of Cardiology clinical criteria for the total population ( p  < 0.05 for both). BACE1-AS was associated with higher prevalence of CAD (odds ratio [OR] = 1.85, 95% confidence interval [CI]: 1.37-2.5), multivessel CAD (OR = 1.36, 95% CI: 1.06-1.75), and with higher number of diseased vascular beds (OR = 1.31, 95% CI: 1.07-1.61, for multiple diseased vascular beds) after multivariable adjustment for traditional cardiovascular risk factors. In the prospective arm, BACE1-AS was an independent predictor of MACE in high cardiovascular risk patients (adjusted hazard ratio = 1.86 per ascending tertile, 95% CI: 1.011-3.43, p  = 0.046)., Conclusion:   BACE1-AS is associated with the incidence and severity of ASCVD., Competing Interests: None declared., (The Author(s).

Aims: Depression and atherosclerotic cardiovascular disease (ASCVD) are commonly clustered in affected patients. Endothelial dysfunction is an early marker of ASCVD while also reported in patients with depression. Emerging evidence suggests that selective serotonin receptor inhibitors (SSRIs) may improve endothelial function. However, clinical studies assessing flow-mediated dilation (FMD), the gold-standard method to evaluate conduit artery endothelial function, in response to SSRIs treatment included limited number of patients and did not provide consistent results. In the present study we aim to evaluate the effect of SSRIs treatment on endothelial function assessed by longitudinal changes in FMD., Methods and Results: We performed a systematic review to retrieve and subsequently meta-analyze eligible studies in patients with depression who received SSRIs and had available measurements of FMD change before and after treatment. In 5 studies and 323 individuals in total, SSRIs were associated with increased FMD at the end of follow-up compared to baseline measurement (pooled mean change 1.97 %, 95 % CI 0.17, 3.77, P = 0.032, I 2  = 87.4 %). These results did not substantially change when analysis was restricted to patients with history of atherosclerotic cardiovascular disease (ASCVD). Similarly, FMD changes were higher in individuals receiving SSRIs compared to not-treated subjects (pooled mean difference 2.5 %. 95 % CI 0.7, 4.2, P < 0.001, I 2  = 82.7 %)., Limitations: Substantial heterogeneity regarding with respect to follow-up duration, demographics, and SSRIs agents., Conclusion: SSRIs significantly improve FMD, the gold-standard marker of endothelial function. Further investigation is warranted for the role of FMD as a possible therapeutic biomarker in patients with depression and established or subclinical ASCVD., Prospero Registration: CRD42021252241., (Copyright © 2022 Elsevier B.V.

Aims: The clinical value of carotid atherosclerosis markers for residual risk stratification in high atherosclerotic cardiovascular disease (ASCVD) risk patients is not established. We aimed to derive and validate optimal values of markers of carotid subclinical atherosclerosis improving risk stratification in guidelines-defined high ASCVD risk patients., Methods and Results: We consecutively analysed high or very high ASCVD risk patients from a cardiovascular (CV) prevention registry (n = 751, derivation cohort) and from the Atherosclerosis Risk in Communities (ARIC) study (n = 2,897, validation cohort). Baseline ASCVD risk was defined using the 2021 European Society of Cardiology guidelines (clinical ESCrisk). Intima-media thickness excluding plaque, average maximal (avg.maxWT), maximal wall thickness (maxWT) and number of sites with carotid plaque were assessed. As primary endpoint of the study was defined the composite of cardiac death, acute myocardial infarction and revascularization after a median of 3.4 years in both cohorts and additionally for 16.7 years in the ARIC cohort., Results: MaxWT &gt; 2.00 mm and avg.maxWT &gt; 1.39 mm provided incremental prognostic value, improved discrimination and correctly reclassified risk over the clinical ESCrisk both in the derivation and the validation cohort (P &lt; 0.05 for net reclassification index, integrated discrimination index and Delta Harrell's C index). MaxWT &lt; 0.9 mm predicted very low probability of CV events (negative predictive value = 97% and 92% in the derivation and validation cohort, respectively). These findings were additionally confirmed for very long-term events in the validation cohort., Conclusion: Integration of carotid ultrasonography in guidelines-defined risk stratification may identify patients at very high-risk in need for further residual risk reduction or at very low probability for events., Competing Interests: Conflict of interest: None declared., (© The Author(s) 2022.

Purpose: The increase in cardiovascular risk after the menopausal transition remains partly explained until today. Further research is needed to identify risk factors potentially modifiable by primary prevention practices. This cross-sectional study, part of a larger prospective project, aims to investigate possible associations between dietary patterns and indices of vascular structure and function among healthy postmenopausal women., Methods: Postmenopausal women (n = 310) without clinically overt cardiovascular disease were recruited consecutively from a University Menopause Clinic over three years. Dietary intake was assessed by a validated food frequency questionnaire and the MedDietScore. In addition, we assessed anthropometric/biochemical parameters, including the Triglyceride-glucose index (TyG-Index), body fat distribution [triceps skinfold (TSF), mid-upper arm circumference (MUAC)] and physical activity. The vascular assessment included carotid-femoral pulse wave velocity (PWV), carotid and femoral-artery intima-media thickness (IMT) and atheromatous plaques presence., Results: Consumption of non-refined cereals was associated with carotid-bulb IMT (R 2  = 5.5% b-coefficient = -0.142; p = 0.011), adjusting for age, physical activity, lipids, systolic blood pressure, smoking, body mass index, insulin resistance, and daily energy intake. PWV was associated with the intake of total dairy products (R 2  = 27.3%, b-coefficient = -0.117; p = 0.017). Higher red meat consumption was related to a greater TyG-index (Model 1, R 2  = 14.3%, b-coefficient=0.121; p = 0.048), an association mediated by total daily energy intake. Higher consumption of alcohol, as well as the MedDietScore, were inversely associated with TSF measurements, significant after Bonferroni correction., Conclusion: Dietary patterns are associated with metabolic indices and subclinical atherosclerosis in postmenopausal women independently of traditional cardiovascular risk factors, total energy intake or physical activity., (© 2022.

Background: The impact of wild-type transthyretin-related cardiac amyloidosis (ATTRwt) on functional and structural peripheral vascular measures is unknown. In the present study, we explored patterns of vascular dysfunction in patients with ATTRwt in comparison to diseases with similar cardiac phenotype., Methods: Treatment-naïve patients with ATTRwt (n = 32) were compared to: 1. Age-and sex-matched reference population without amyloidosis (n = 32), 2. Age-and sex-matched patients with systemic AL amyloidosis (n = 32), and 3. patients with cardiac AL amyloidosis (AL-HF, n = 23) or elderly patients with heart failure with preserved ejection fraction (HFpEF) (n = 16). All subjects underwent peripheral vascular assessment using carotid artery ultrasonography, brachial artery flow-mediated dilation (FMD), measurement of arterial stiffness and aortic hemodynamics including heart rate-adjusted time of return of reflected waves (Tr/HR)., Results: After adjustment for traditional cardiovascular risk factors and coronary artery disease (core model), peripheral and aortic blood pressures (BP) were lower in patients with ATTRwt (p < 0.05) whereas other vascular markers were preserved compared to the reference non-amyloidosis group. ATTRwt was independently associated with lower BP and longer Tr/HR compared to AL. Compared to AL-HF, FMD was lower in ATTRwt (p = 0.033). ATTRwt patients had lower BP and higher Tr/HR than HFpEF (p < 0.05). By ROC analysis, Tr/HR discriminated ATTRwt vs. AL-HF (sensitivity 93%, specificity 75%) and HFpEF (sensitivity 100%, specificity 94%) and lower FMD increased the likelihood for ATTRwt at low Tr/HR values., Conclusion: ATTRwt patients present a distinct peripheral vascular fingerprint which is different from AL-HF or HFpEF, consisting of lower peripheral and aortic BP, prolonged Tr/HR and FMD at reference-population range., (Copyright © 2022 Elsevier B.V.

Background: Patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS) are at high residual risk for long-term cardiovascular (CV) mortality. Cathepsin S (CTSS) is a lysosomal cysteine protease with elastolytic and collagenolytic activity that has been involved in atherosclerotic plaque rupture., Objectives: The purpose of this study was to determine the following: 1) the prognostic value of circulating CTSS measured at patient admission for long-term mortality in NSTE-ACS; and 2) its additive value over the GRACE (Global Registry of Acute Coronary Events) risk score., Methods: This was a single-center cohort study, consecutively recruiting patients with adjudicated NSTE-ACS (n = 1,112) from the emergency department of an academic hospital. CTSS was measured in serum using enzyme-linked immunosorbent assay. All-cause mortality at 8 years was the primary endpoint. CV death was the secondary endpoint., Results: In total, 367 (33.0%) deaths were recorded. CTSS was associated with increased risk of all-cause mortality (HR for highest vs lowest quarter of CTSS: 1.89; 95% CI: 1.34-2.66; P < 0.001) and CV death (HR: 2.58; 95% CI: 1.15-5.77; P = 0.021) after adjusting for traditional CV risk factors, high-sensitivity C-reactive protein, left ventricular ejection fraction, high-sensitivity troponin-T, revascularization and index diagnosis (unstable angina/ non-ST-segment elevation myocardial infarction). When CTSS was added to the GRACE score, it conferred significant discrimination and reclassification value for all-cause mortality (Delta Harrell's C: 0.03; 95% CI: 0.012-0.047; P = 0.001; and net reclassification improvement = 0.202; P = 0.003) and CV death (AUC: 0.056; 95% CI: 0.017-0.095; P = 0.005; and net reclassification improvement = 0.390; P = 0.001) even after additionally considering high-sensitivity troponin-T and left ventricular ejection fraction., Conclusions: Circulating CTSS is a predictor of long-term mortality and improves risk stratification of patients with NSTE-ACS over the GRACE score., Competing Interests: Funding Support and Author Disclosures This research was funded by the German Research Foundation DFG (SFB834 project number 75732319) and the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation program (grant agreement No 759248) (to Dr Stellos).
