Treatment of Anemia Associated with Chronic Kidney Disease: Plea for Considering Physiological Erythropoiesis.

Traditionally, the treatment of anemia associated with chronic kidney disease (CKD) involves prescribing erythropoiesis-stimulating agents (ESAs) or iron preparations. The effectiveness and safety of ESAs and iron have been established. However, several clinical issues, such as hyporesponsiveness to ESAs or defective iron utilization for erythropoiesis, have been demonstrated. Recently, a new class of therapeutics for renal anemia known as hypoxia-inducible factor (HIF)/proline hydroxylase (PH) inhibitors has been developed. Several studies have reported that HIF-PH inhibitors have unique characteristics compared with those of ESAs. In particular, the use of HIF-PH inhibitors may maintain target Hb concentration in patients treated with a high dose of ESAs without increasing the dose. Furthermore, several recent studies have demonstrated that patients with CKD with defective iron utilization for erythropoiesis had a high risk of cardiovascular events or premature death. HIF-PH inhibitors increase iron transport and absorption from the gastrointestinal tract; thus, they may ameliorate defective iron utilization for erythropoiesis in patients with CKD. Conversely, several clinical problems, such as aggravation of thrombotic and embolic complications, diabetic retinal disease, and cancer, have been noted at the time of HIF-PH inhibitor administration. Recently, several pooled analyses of phase III trials have reported the non-inferiority of HIF-PH inhibitors regarding these clinical concerns compared with ESAs. The advantages and issues of anemia treatment by ESAs, iron preparations, and HIF-PH inhibitors must be fully understood. Moreover, patients with anemia and CKD should be treated by providing a physiological erythropoiesis environment that is similar to that of healthy individuals.

The effect of Empagliflozin on echocardiographic parameters in diabetic patients after acute myocardial infarction: A systematic review and meta-analysis with trial sequential analysis.

Patients with diabetes mellitus (DM) are at higher risk of cardiovascular events, particularly acute myocardial infarction (MI). Sodium-glucose cotransporter 2 inhibitors (SGLT2i) can improve cardiac outcomes among heart failure individuals, however, the effects on acute myocardial infarction remain unclear. This meta-analysis investigates the impact of empagliflozin in diabetic patients following acute myocardial infarction. We comprehensively searched PubMed, Scopus, Cochrane, and Web of Science through August 10th, 2023. We included studies comparing empagliflozin versus placebo in diabetes patients with acute myocardial infarction. We used Revman to report the data as mean difference (MD) and 95% confidence interval (CI), and our effect size with a random effects model. Additionally, we performed Trial Sequential Analysis (TSA) to test the robustness of the results. The study protocol was published on PROSPERO with ID: CRD42023447733. Five studies with a total of 751 patients were included in our analysis. Empagliflozin was effective to improve LVEF% (MD: 1.80, 95% CI [0.50, 3.10], p = 0.007), left ventricular end-diastolic volume (LVEDV) (MD: -9.93, 95% CI [-16.07, -3.80], p = 0.002), and left ventricular end-systolic volume (LVESV) (MD: -7.91, 95% CI [-11.93, -3.88], p = 0.0001). However, there was no difference between empagliflozin and placebo groups in terms of NT-pro BNP (MD: - 136.59, 95% CI [-293.43, 20.25], p = 0.09), and HbA1c (MD: -0.72, 95% CI [-1.73, 0.29], p = 0.16). Additionally, empagliflozin did not prevent hospitalization due to heart failure (RR: 0.59, 95% CI [0.16, 2.24], p = 0.44, I-squared = 0%), and mortality (RR: 1.34, 95% CI [0.15,11.90], p = 0.79, I-squared = 25%). Empagliflozin initiation in diabetic patients following acute MI may improve echocardiographic parameters. However, empagliflozin might not be effective in heart failure prevention and optimal glycemic control in this patient population. Further large-scale trials are warranted to ascertain our findings.

Diffuse large B-cell lymphoma with heart involvement: the relevance of the multidisciplinary and multiparameter approach

Lymphoma patients are at high risk of cardiovascular events due to anthracycline cardiotoxicity and, in rare cases, related to heart infiltration. The presence of cardiac masses adds further complexity to the management of lymphoma patients beyond myocardial chemotherapy-related toxicity, given possible unpredictable acute complications such as arrhythmias, atrioventricular block, myocardial ischemia, pericardial effusion and cardiac tamponade. Here we describe the clinical presentation and successful multidisciplinary management of diffuse large B-cell lymphoma with multifocal cardiac involvement identified by total body 18FDG positron emission tomography performed at disease staging.

Quantification of subclinical plaque characteristics and perivascular fat using coronary computed tomography angiography (CCTA) among individuals with human immunodeficiency virus (HIV).

People infected with human immunodeficiency virus (PIWH) have a higher risk of cardiovascular events. This study was designed to compare the differences in plaque characteristics and perivascular fat between subclinical coronary atherosclerosis in PIWH and healthy controls (HC) by coronary computed tomography angiography (CCTA). We also assessed the associations between human immunodeficiency virus (HIV) infection, antiretroviral therapy (ART), and coronary artery disease (CAD). This cross-sectional study included a total of 158 PIWH and 79 controls. CCTA was used to evaluate coronary artery plaque prevalence, coronary stenosis severity, plaque composition, plaque volume, and perivascular fat attenuation index (FAI). Logistic regression analyses were used to assess the associations between the prevalence of coronary artery plaque and HIV-related clinical indicators. There was no difference in total coronary artery plaque prevalence between PIWH and controls (44.3% vs. 32.9%; P=0.09), but the prevalence of noncalcified plaque was significantly higher in PIWH compared with the controls (33.5% vs. 16.5%; P=0.006). After adjustment for age, sex, statin use, and family history of cardiovascular disease (CVD), the prevalence of noncalcified plaque remained 2 times higher in PIWH [odds ratio (OR), 2.082; 95% confidence interval (CI): 1.007-4.304; P=0.048]. The perivascular FAI measured around the left anterior descending artery (LAD) was higher in PIWH (-71.4±5.7 vs. -73.5±7.0; P=0.03) compared with that of the controls. The intra-group analyses of PIWH suggested that the decrease in nadir CD4+ T-cell count was associated with the increased prevalence of noncalcified plaque (OR, 4.139; 95% CI: 1.312-13.060; P=0.02). PIWH have a higher risk of developing noncalcified plaque and greater perivascular fat. In addition, the increased noncalcified plaque prevalence in PIWH may be associated with the immunodeficiency caused by HIV.

Association of Hematological Biomarkers of Inflammation with 10-Year Major Adverse Cardiovascular Events and All-Cause Mortality in Patients with Metabolic Dysfunction-Associated Steatotic Liver Disease: The ARIC Study.

Metabolic dysfunction-associated steatotic liver disease (MASLD) increases the risk of cardiovascular disease and existing evidence indicates that MASLD affects the cardiovascular system through systemic inflammation. Our aim was to assess the association of hematological biomarkers of inflammation with the 10-year risk of major adverse cardiovascular events (MACE) and all-cause mortality in MASLD patients. A total of 1858 MASLD participants from the Atherosclerosis Risk in Communities cohort study at visit 2 (1990-1992) were included. A total of 1338 non-MASLD participants were also included in the comparison. At baseline, hematological biomarkers of inflammation such as leukocytes, neutrophils, lymphocytes, monocytes, and C-reactive protein (CRP) were measured. Participants were followed up for MACE and all-cause mortality for a period of 10 years. Multivariate adjusted Cox models were used to estimate hazard ratios (HR). The 10-year MACE was higher in MASLD participants than in non-MASLD participants (20.8% vs 9.3%). Monocytes (HR 1.114, [95% CI, 1.022-1.216] per 1-SD, P=0.015) and CRP (HR 1.109 [95% CI, 1.032-1.190] per 1-SD, P=0.005) were associated with an increased 10-year risk of MACE, independent of other cardiovascular risk factors. This association was specific to the MASLD population. None of these hematological biomarkers demonstrated a significant association with 10-year all-cause mortality. Increased levels of monocytes and CRP were associated with an increased 10-year risk of MACE in the MASLD population. Hematological biomarkers of inflammation may help identify MASLD populations at higher risk for cardiovascular events.

Recent Insights in Noninvasive Diagnostic for the Assessment of Kidney and Cardiovascular Outcome in Kidney Transplant Recipients.

Kidney transplantation improves quality of life and prolongs survival of patients with end-stage kidney disease. However, kidney transplant recipients present a higher risk for cardiovascular events compared to the general population. Risk assessment for graft failure as well as cardiovascular events is still based on invasive procedures. Biomarkers in blood and urine, but also new diagnostic approaches like genetic or molecular testing, can be useful tools to monitor graft function and to identify patients of high cardiovascular risk. Many biomarkers have been introduced, whereas most of these biomarkers have not been implemented in clinical routine. Here, we discuss recent developments in biomarkers and diagnostic models in kidney transplant recipients. Because many factors impact graft function and cardiovascular risk, it is most likely that no biomarker will meet the highest demands and standards. We advocate to shift focus to the identification of patients benefitting from molecular and genetic testing as well as from analysis of more specific biomarkers instead of finding one biomarker fitting to all patients.

Echocardiographic Parameters of Left Atrial Structure and Function and Clinical Outcomes at 2 Years in Elderly Patients With Atrial Fibrillation - The ANAFIE Echocardiographic Substudy.

This prospective ANAFIE Registry substudy investigated the relationship between the echocardiographic parameters of left atrial (LA) structure and function and clinical outcomes at 2 years among atrial fibrillation (AF) patients aged ≥75 years. Outcomes of 1,474 elderly non-valvular AF (NVAF) patients who underwent transthoracic echocardiography at baseline were analyzed by categories of maximum LA volume index (max. LAVi) and LA emptying fraction (LAEF) total. Baseline mean±standard deviation LAEF total and max. LAVi were 28.2±14.9% and 54.2±25.9 mL/m2, respectively. Proportions of oral anticoagulant (OAC), direct OAC, and warfarin use were 92.7%, 68.7%, and 24.0%, respectively. Patients with LAEF total ≤45.0% (n=1,213) vs. >45.0% (n=224) were at higher risk of cardiovascular events (hazard ratio [HR]: 2.19, P=0.021) and heart failure (HF) hospitalization (HR: 2.25, P=0.045). Risk of all-cause death was higher with max. LAVi >48.0 mL/m2(n=656) vs. ≤48.0 mL/m2(n=621) (HR: 1.69, P=0.048). Subgroups with abnormal LA function and structure had increased incidence of cardiac/cardiovascular events and HF hospitalization. No significant interaction was observed between echocardiographic parameters and OAC type. Elderly Japanese patients with NVAF and LAEF total ≤45.0% were at higher risk of cardiovascular events and HF hospitalization, and those with max. LAVi >48.0 mL/m2were at higher risk of all-cause death.

A 3-Dimensional Ablation At Patient With Tachycardia Right Ventricular Outflow Track (RVOT) Origin: First Experienced in Saiful Anwar General Hospital Malang

Background: Premature ventricular complexes (PVCs) occur commonly in general population. It can occur in patient without structural heart disease as well as those with any form of cardiac disease. Commonly PVCs are asymptomatic, but in patients with frequent PVCs causing palpitations, syncope or dizziness, easily to fatigue, or shortness of breath. PVCs has been connected with a more than two-fold higher risk of cardiovascular events including stroke, mortality and also associated with arrhythmias or cardiomyopathy. Medications can be used to suppress PVCs but when drug therapy is ineffective, PVC ablation is reasonable to eliminate symptoms and treat or prevent PVC-induced cardiomyopathy. Case Presentation: A hypertension and menopause, 57-year-old woman, frequently complained about palpitation with shortness of breath, dizziness and sometimes near syncope since 2017, occurring both at rest and with mild activities. After serial examinations, found Frequent PVC (39%) with RVOT-Origin and reduced ejection fraction (EF 48%), then conclude with Suspect Tachycardia Induced cardiomyopathies. She performs cardiac electrophysiological study and continue with 3-Dimentional Ablation with Radiofrequency (RFA) at RVOT in Saiful Anwar Hospital, that is The First 3-Dimension Ablation in East Java. 1 year follow up shows no recurrency and successful to improve quality of life of the patient Discussion: According to guideline, catheter ablation is class I recommendation for patients with symptomatic outflow tract ventricular arrhythmias if medications are ineffective, not tolerated, or patient’s choose Conclusion: Three-Dimensional Ablation at patient with Right Ventricular Outflow Track Tachycardia, can successfully eliminate PVCs with no recurrency in 1 year follow-up.

Evaluating the Efficacy and Safety of Aspirin for Primary Cardiovascular Prevention in Asian Patients with Type 2 Diabetes: A Population-Based and Propensity Score-Matched Study.

The risk of developing cardiovascular disease is significantly higher for individuals with diabetes compared to those without. Aspirin has been widely used for primary prevention in diabetic patients. However, evidence is limited in the Asian population. We aimed to compare the effectiveness and safety of aspirin versus placebo for primary cardiovascular prevention in the Asian population with type 2 diabetes. In this study, we performed propensity score matching with non-aspirin users from January 2006 to December 2015 (n = 37,095 in each group after matching, PSM). We analyzed the incidence risk of all-cause mortality, composite cardiovascular events, and hospitalized major bleeding. The propensity score-matched (PSM) cohort of patients who received aspirin within one year of diabetes diagnosis was compared with the non-aspirin diabetic (DM) cohort. Baseline characteristics were balanced between the two groups. The median follow-up duration was 78 months. Aspirin users exhibited a slightly but significantly lower rate of all-cause mortality (HR: 0.92; 95% CI: 0.87 to 0.96). However, they also had a significantly higher composite cardiovascular risk (HR: 1.34; 95% CI: 1.28-1.40), including non-fatal acute myocardial infarction (HR: 1.33; 95% CI: 1.18 to 1.50), non-fatal ischemic stroke (HR: 1.38; 95% CI: 1.30 to 1.45), heart failure (HR: 1.18; 95% CI: 1.09 to 1.27), and coronary revascularization (HR: 1.94; 95% CI: 1.73 to 2.17). Aspirin users also faced a significantly higher risk of hospitalized major bleeding (HR: 1.08; 95% CI: 1.03 to 1.14). The presence of one or more additional risk factors did not influence the effectiveness and safety outcomes of aspirin, according to stratified analysis. In conclusion, in this real-world Asian diabetic population, aspirin was associated with a significantly lower mortality risk but also with higher risks of cardiovascular events and hospitalized bleeding. Aspirin may not play a role in the primary prevention of cardiovascular disease in such patients, regardless of additional risk factors.

Ten-year risk of cardiovascular events among the adult population of West Tripura District of India by the Framingham risk score: A cross-sectional study.

Cardiovascular diseases (CVDs) are the leading causes of mortality worldwide. Predicting the 10-year risk of cardiovascular events (CVEs) may save lives through timely intervention. Framingham risk scoring (FRS) can effectively predict this risk. This study aimed to estimate the 10-year risk of CVE using FRS and to estimate the prevalence of CVD risk factors and their associations with FRS among adults in the West Tripura District of India. This community-based cross-sectional study was conducted from 1 November 2019 to 30 November 2021 in the West Tripura District of India, using FRS 2008 and a pretested interview schedule among 290 individuals aged ≥ 30 years chosen by multistage sampling. The majority, that is 61.7%, of the study subjects had low risk, 18.6% had intermediate risk and 19.7% had high risk of CVE within 10 years. The prevalence of hypertension was 55.6%; diabetes mellitus, 55.9%; smoking, 96.2%; dyslipidaemia, 34.3%; alcohol consumption, 96.2%; physical inactivity, 54%; and obesity, 64.6%. The bivariate analysis detected a significant association of FRS with age, sex, residence, literacy, marital status, obesity, smoking, alcoholism, blood pressure (BP), high-density lipoprotein cholesterol (HDL-C) and glycaemic status of the study subjects. The logistic regression analysis has identified age >50 years, male sex, hypertension, smoking and diabetes mellitus as significant determinants of high FRS. Adults living in the West Tripura District of India have a high prevalence of CVD risk factors. About one-fifth of this population has a high risk of CVE in 10 years. Controlling hypertension, smoking and diabetes mellitus may help reduce this risk.

Primary Atriopathy in Mitral Valve Prolapse: Echocardiographic Evidence and Clinical Implications.

Prominent multi-scallop systolic leaflet displacement toward the left atrium (atrialization) is typically observed in bileaflet mitral valve prolapse (MVP) with mitral annular disjunction. We hypothesized that mitral leaflet atrialization is associated with an underlying left atrial (LA) myopathy characterized by progressive structural and functional abnormalities, irrespective of mitral regurgitation (MR) severity. We identified 334 consecutive patients with MVP, no prior atrial fibrillation, and comprehensive clinical and echocardiographic data. LA function was assessed by LA reservoir strain, LA function index, and LA emptying fraction. We also classified the stage of LA remodeling based on LA enlargement and LA reservoir strain (stage 1: no remodeling; stage 2: mild remodeling; stage 3: moderate remodeling; and stage 4: severe remodeling). The primary end point was the composite risk of sudden arrhythmic death, heart failure hospitalization, or the new onset of atrial fibrillation. Bileaflet MVP with no or mild MR had a lower LA reservoir strain (P=0.04) and LA function index (P<0.001) compared with other MVP subtypes. In multivariable linear regression adjusted for cardiovascular risk factors and MR ≥moderate, bileaflet MVP remained significantly associated with lower LA function parameters (all P<0.05). There was a significant increase in the risk of events as the LA reservoir strain and LA remodeling stage increased (P<0.001). In multivariable analysis, stage 4 of LA remodeling remained significantly associated with a higher risk of events compared with stage 1 (hazard ratio, 6.09 [95% CI, 1.69-21.9]; P=0.006). In a large MVP registry, bileaflet involvement is associated with reduced LA function regardless of MR severity, suggesting a primary atriopathy in this MVP subtype. Abnormal LA function, particularly when assessed through a multiparametric approach, is linked to a higher risk of cardiovascular events and may improve risk stratification in MVP, even in those without significant MR.

High stress hyperglycemia ratio predicts adverse clinical outcome in patients with coronary three-vessel disease: a large-scale cohort study

BackgroundCoronary three-vessel disease (CTVD) accounts for one-third of the overall incidence of coronary artery disease, with heightened mortality rates compared to single-vessel lesions, including common trunk lesions. Dysregulated glucose metabolism exacerbates atherosclerosis and increases cardiovascular risk. The stress hyperglycemia ratio (SHR) is proposed as an indicator of glucose metabolism status but its association with cardiovascular outcomes in CTVD patients undergoing percutaneous coronary intervention (PCI) remains unclear.Methods10,532 CTVD patients undergoing PCI were consecutively enrolled. SHR was calculated using the formula: admission blood glucose (mmol/L)/[1.59×HbA1c (%)–2.59]. Patients were divided into two groups (SHR Low and SHR High) according to the optimal cutoff value of SHR. Multivariable Cox regression models were used to assess the relationship between SHR and long-term prognosis. The primary endpoint was cardiovascular (CV) events, composing of cardiac death and non-fatal myocardial infarction (MI).ResultsDuring the median follow-up time of 3 years, a total of 279 cases (2.6%) of CV events were recorded. Multivariable Cox analyses showed that high SHR was associated with a significantly higher risk of CV events [Hazard Ratio (HR) 1.99, 95% Confidence interval (CI) 1.58–2.52, P < 0.001). This association remained consistent in patients with (HR 1.50, 95% CI 1.08–2.10, P = 0.016) and without diabetes (HR 1.97, 95% CI 1.42–2.72, P < 0.001). Additionally, adding SHR to the base model of traditional risk factors led to a significant improvement in the C-index, net reclassification and integrated discrimination.ConclusionsSHR was a significant predictor for adverse CV outcomes in CTVD patients with or without diabetes, which suggested that it could aid in the risk stratification in this particular population regardless of glucose metabolism status.

Metabolomics and Cardiovascular Risk in Patients with Heart Failure: A Systematic Review and Meta-Analysis.

The associations of plasma metabolites with adverse cardiovascular (CV) outcomes are still underexplored and may be useful in CV risk stratification. We performed a systematic review and meta-analysis to establish correlations between blood metabolites and adverse CV outcomes in patients with heart failure (HF). Four cohorts were included, involving 83 metabolites and 37 metabolite ratios, measured in 1158 HF patients. Hazard ratios (HR) of 42 metabolites and 3 metabolite ratios, present in at least two studies, were combined through meta-analysis. Higher levels of histidine (HR 0.74, 95% CI [0.64; 0.86]) and tryptophan (HR 0.82 [0.71; 0.96]) seemed protective, whereas higher levels of symmetric dimethylarginine (SDMA) (HR 1.58 [1.30; 1.93]), N-methyl-1-histidine (HR 1.56 [1.27; 1.90]), SDMA/arginine (HR 1.38 [1.14; 1.68]), putrescine (HR 1.31 [1.06; 1.61]), methionine sulfoxide (HR 1.26 [1.03; 1.52]), and 5-hydroxylysine (HR 1.25 [1.05; 1.48]) were associated with a higher risk of CV events. Our findings corroborate important associations between metabolic imbalances and a higher risk of CV events in HF patients. However, the lack of standardization and data reporting hampered the comparison of a higher number of studies. In a future clinical scenario, metabolomics will greatly benefit from harmonizing sample handling, data analysis, reporting, and sharing.

#233 Marine n-3 polyunsaturated fatty acids and cardiovascular events in patients with end-stage renal disease receiving hemodialysis

Abstract Background and Aims Cardiovascular (CV) disease is the leading cause of death in patients with end-stage renal disease (ESRD) receiving hemodialysis (HD). The two major marine n-3 polyunsaturated fatty acids (n-3 PUFAs) eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) may have cardioprotective effects. This study aimed to investigate the predictive value of plasma n-3 PUFAs on CV events and all-cause mortality in patients with ESRD receiving HD. Method A validated prospective multicenter cohort study of 336 patients with ESRD receiving HD with 5 years of follow-up was conducted. Blood samples were collected at baseline and analyzed for the plasma levels of EPA and DHA expressed as a weight percentage (wt%) of total plasma fatty acids. The primary outcome was CV events defined as acute myocardial infarction, unstable angina pectoris, stroke, transient ischemic attack, peripheral artery disease (PAD), or cardiovascular mortality. The secondary outcomes were all-cause mortality and each individual component of CV events. The sum of EPA and DHA (EPA+DHA) was used in all analyses and expressed as n-3 PUFAs in wt%. The population was divided into three groups according to n-3 PUFA tertiles. Kaplan-Meier curves and multivariable Cox regressions adjusted for relevant confounders were used to analyze the association between plasma n-3 PUFA levels and study outcomes. Results Median follow-up time was 5.05 years (IQR, 5.02-5.07). Mean age was 65 ± 15 years and plasma n-3 PUFA levels ranged from 2.1 to 16.8 wt%, with a median of 5.7 wt% (IQR, 4.72-6.96 wt%). During follow-up 60% of the cohort died, 17% died of CV disease, and 42% had a CV event. Figure 1 shows the unadjusted associations between the plasma n-3 PUFA tertiles and the risk of CV events. A n-3 PUFA level between 5.06-6.52 wt% was associated with a 36% lower risk of CV events [unadjusted HR 0.64 (95% CI 0.43-0.96)]. Additionally, a n-3 PUFA level above 6.52 wt% was associated with a 34% lower risk of CV events [unadjusted HR 0.66 (95% CI 0.44-0.98)], both in comparison to levels below 5.06 wt%. After adjusting for relevant confounders, as shown in Figure 2, n-3 PUFA levels between 5.06 to 6.52 wt% were associated with a significantly lower risk of CV events [adjusted HR 0.60 (95% CI 0.40-0.92)], PAD [adjusted HR 0.44 (95% CI 0.22-0.88)], and all-cause mortality [adjusted HR 0.61 (95% CI 0.42-0.86)], when compared to levels below 5.06 wt%. Conclusion In this study of patients with ESRD receiving HD, a low plasma level of n-3 PUFA was associated with a higher risk of CV events, peripheral artery disease, and all-cause mortality.

#2768 Evaluation of vascular access via a TRIAGE system for hemodialysis: a tool to assess clinical risk in hemodialysis patients

Abstract Background and Aims The type and efficacy of vascular access (VA) in hemodialysis (HD) play pivotal roles in determining the quality of treatment and, eventually, the clinical outcome of patients. Low dialysis quality due to suboptimal vascular access functioning is a risk factor for increased cardiovascular mortality in HD. In a prior study involving 754 patients undergoing chronic HD, we demonstrated that a VA TRIAGE system effectively identified vascular accesses at a higher risk of complications both in patients with arteriovenous fistula (AVF) and in patients with central venous catheters (CVC). The TRIAGE categorization is generated monthly through a scoring system recording several parameters of each session, like blood flow, VA pressure, end HD circuit clots, external VA examination, and KT/V. Based on threshold values, VA performance is classified as Green (G), Yellow (Y), or Red). In this study, we aimed to assess whether the TRIAGE system, by identifying poorly functioning VA, could also identify patients at a higher risk of cardiovascular events. Method In this interventional prospective, blinded multicentre study, each centre utilized the VA TRIAGE electronic spreadsheet without knowledge of the generated triage. After six months of system implementation, a two-year follow-up (01/01/2020 - 01/12/2021) was conducted to record cardiovascular events (myocardial infarction, cerebrovascular accident, peripheral vasculopathy, unstable angina, atrial fibrillation, heart failure). External reviewers assessed the records, and a minimum of three months of VA follow-up was necessary for patient enrolment. Results From 18 HD centres, 757 patients were enrolled, with an average age of 64.5 ± 15.5 years; 27% were diabetics, undergoing HD for 24.4 ± 32.4 months; 369 (48.7%) had AVF, and 388 (51.3%) had a permanent CVC. Over 11.4±5.6 months of follow-up (range 3-23) and 108, 537 HD sessions recorded in the TRIAGE system, 100 cardiovascular-related events occurred during 16.3 ± 2.2 months of follow-up (range 3-23). The VA TRIAGE was: 60% Green, 35% Yellow, and 5% Red. The Green Triage group demonstrated a lower incidence of cardiovascular events independent of VA type (25% vs. 75%; P: 0.01) and a higher duration free from cardiovascular events (AVF Green vs. AVF Yellow-Red: log-rank test: 0.04). Conclusion Our VA TRIAGE system not only identifies poorly functioning vascular accesses but also effectively assesses the clinical risk in patients undergoing HD. This outcome, in our view, is linked to the diminished quality of dialysis resulting from lower VA function in the yellow and red Triage groups compared to the green Triage group. Integrating the VA TRIAGE system with additional clinical parameters enhances its capacity to assess the clinical risk of HD patients. This approach offers a more comprehensive evaluation, potentially improving the identification of patients at higher cardiovascular risk.

The effect of antiarrhythmic medications on the risk of cardiovascular outcomes in patients with atrial fibrillation and coronary artery disease

BackgroundWhile current guidelines recommend amiodarone and dronedarone for rhythm control in patients with atrial fibrillation (AF) and coronary artery disease (CAD), there was no comparative study of antiarrhythmic drugs (AADs) on the cardiovascular outcomes in general practice. MethodsThis study included patients with AF and CAD who received their first prescription of amiodarone, class Ic AADs (flecainide, propafenone), dronedarone or sotalol between January 2016 and December 2020. The primary outcome was a composite of hospitalization for heart failure (HHF), stroke, acute myocardial infarction (AMI), and cardiovascular death. We used Cox proportional regression models, including with inverse probability of treatment weighting (IPTW), to estimate the relationship between AADs and cardiovascular outcomes. ResultsAmong the AF cohort consisting of 8752 patients, 1996 individuals had CAD, including 477 who took dronedarone and 1519 who took other AADs. After a median follow-up of 38 months, 46.3% of patients who took dronedarone and 54.4% of patients who took other AADs experienced cardiovascular events. Compared to dronedarone, the use of other AADs was associated with increased cardiovascular events after adjusting for covariates (hazard ratio [HR] 1.531, 95% confidence interval [CI] 1.112–2.141, p = 0.023) and IPTW (HR 1.491, 95% CI 1.174–1.992, p = 0.012). The secondary analysis showed that amiodarone and class Ic drugs were associated with an increased risk of HHF. The low number of subjects in the sotalol group limits data interpretation. ConclusionFor patients with AF and CAD, dronedarone was associated with better cardiovascular outcomes than other AADs. Amiodarone and class Ic AADs were associated with a higher risk of cardiovascular events, particularly HHF.

Type 2 diabetes mellitus aggravates coronary atherosclerosis in hypertensive individuals based on coronary CT angiography: a retrospective propensity score-based study.

The effect of type 2 diabetes mellitus (T2DM) on coronary atherosclerosis detected on coronary computed tomography angiography (CCTA) in hypertensive patients has attracted increasing attention. This study investigated the relationships of T2DM with coronary artery plaque characteristics and semiquantitative CCTA scores in hypertensive patients. In this single-center study, 1,700 hypertensive patients, including 850 T2DM [HT(T2DM+)] and 850 non-T2DM [HT(T2DM-)] individuals, were retrospectively analyzed after propensity matching. Plaque type, extent, coronary stenosis, segment involvement score (SIS), segment stenosis score (SSS), and CT-based Leaman score (CT-LeSc) based on CCTA were assessed and compared between the two groups. HT(T2DM+) patients had more coronary segments with calcified plaque (2.08 ± 2.20 vs. 1.40 ± 1.91), mixed plaque (2.90 ± 2.87 vs. 2.50 ± 2.66), nonobstructive stenosis (4.23 ± 2.44 vs. 3.62 ± 2.42), and obstructive stenosis (1.22 ± 2.18 vs. 0.78 ± 1.51), a lower proportion of 1-vessel disease (15.3% vs. 25.5%), a higher proportion of 3-vessel disease (59.6% vs. 46.7%), and higher SIS (5.5 ± 3.1 vs. 4.4 ± 3.0), SSS (10.3 ± 8.5 vs. 7.7 ± 7.1), and CT-LeSc (9.4 ± 5.6 vs. 7.9 ± 5.2) than HT(T2DM-) patients (all P-values <0.05). Multivariable analysis revealed that T2DM was an independent risk factor for calcified plaque [odds ratio (OR) = 2.213], obstructive coronary artery disease (CAD) (OR = 1.271), multivessel disease (OR = 1.838), SIS > 4 (OR = 1.910), SSS > 6 (OR = 1.718), and CT-LeSc > 5 (OR = 1.584) in hypertension population (all P-values <0.05). T2DM was independently associated with the presence of calcified coronary artery plaque and increased the risk of obstructive CAD, multivessel disease, and CT-LeSc > 5 in hypertensive patients. More attention should be given to the assessment and management for coronary atherosclerosis in hypertensive patients with T2DM, as this population may have a higher risk of cardiovascular events.

AN ACUTE MYOCARDIAL INFARCTION IN A VERY YOUNG MAN DUE TO HYPERHOMOCYSTEINEMIA

Abstract Introduction A young 17–year–old boy smoker and obese was admitted to our cardiology unit for continuous oppressive chest pain radiating to the left arm that had arisen three days earlier. In the emergency room, he had performed blood tests with evidence of an increased troponin and an electrocardiogram that showed mild ST–elevation in inferior leads with ST depression in aVL. We performed an urgent transthoracic echocardiography examination that was unremarkable Investigation Once diagnosed with acute ST–segment elevation myocardial infarction, the patient underwent emergency coronary angiography. Coronary angiography highlighted an intermediate stenosis of the first branch diagonal to the proximal tract and a possible occlusion of the periapical branch of the anterior descending artery. It was decided not to perform PTCA as we could not exclude a distal coronary dissection and considering the vessel was of small caliber. We decided to complete the diagnostic process by performing a cardiac MRI showing edema in the apex and distal inferior wall and transmural gadolinium enhancement at the level of the septum and inferior wall of the distal section. In the context of the damaged wall a focal area of hypointensity to be referred to the "no–reflow" phenomenon Management The patient was treated with DAPT, low molecular weight heparin and high dose statin. A few hours after the coronary angiography the patient stopped having chest pain and remained asymptomatic for the rest of the hospital stay. We performed complete blood tests including with evidence of hyperhomocysteinemia. The lipid panel was normal. Hematological consultation recommended folate and Vitamine B12 treatment. After 12 months the patient is asymptomatic, has stopped smoking and continues to take DAPT. He repeated the echocardiogram which showed no alterations. Genetic testing was performed after hospital discharge and was positive for Methylenetetrahydrofolate reductase (MTHFR) homozygous mutation Conclusion Our clinical case shows a rare case of acute myocardial infarction in a very young person. Diagnosis and treatment were complicated by the extreme distality of the occlusion and the few modifiable risk factors identified (smoker, obesity and hyperhomocysteinemia). Hyperhomocysteinemia is an often underestimated cardiovascular risk factor associated with a high risk of cardiovascular events and multivessel coronary disease that should be sought in all young patients with AMI.

Evaluating cardiovascular risk in metabolic steatosis with precision medicine non-invasive approaches: insights from a cohort study.

Metabolic associated steatotic liver disease (MASLD) is the most common liver condition. It is associated with increased liver-related morbidity and mortality, and also with high risk of cardiovascular events (CVD), representing itself an independent risk factor for it. This makes MASLD a presentation of high interest for internal medicine, also because of its association with metabolic syndrome (MetS). It is crucial to assess its risks in a noninvasive way. With the aim of finding specific risk profiles for CVD development in MASLD by performing a noninvasive assessment of: (1) preclinical signs of endothelial dysfunction (ED); (2) clinical assessment of CVD risk by Framingham Heart Risk Score (FHRs); (3) genomic characterization of MASLD associated polymorphisms; (4) specific untargeted metabolomic profiles, we enrolled 466 MASLD patients non-invasively classified in 4 group of liver fibrosis severity (group-A: low-fibrosis risk, group-B: high-fibrosis risk, group-C: MASLD-cirrhosis, group-D: MASLD-HCC) and 73 healthy controls. FHRs was similar in controls and low-fibrosis group and significantly higher in high-fibrosis patients, cirrhosis, and HCC, increasing among classes. At a multivariable regression, FHRs wasassociated with liver disease severity and diabetes. 38.2% of patients had altered EndoPAT,resembling ED.Patients with high FHRs (> 40%) and ED had different metabolomics compared to those without ED. Our study reveals that a deep, non-invasive characterization of MASLD patients through precision medicine approaches (untargeted metabolomics, SNPs, ED assessment) was able to show a peculiar pattern in MASLD patients with increased CVD risk, mostly correlated with liver disease severity.

Coronary Artery Plaque Phenotype and 5-Year Clinical Outcomes in Older Patients with Non-ST Elevation Acute Coronary Syndrome.

Lesions with thin-cap fibroatheroma (TCFA), small luminal area and large plaque burden (PB) have been considered at high risk of cardiovascular events. Older patients were not represented in studies which demonstrated correlation between clinical outcome and plaque characteristics. This study aims to investigate the prognostic role of high-risk plaque characteristics and long-term outcome in older patients presenting with non-ST elevation acute coronary syndrome (NSTEACS). This study recruited older patients aged 75 years with NSTEACS undergoing virtual-histology intravascular ultrasound (VH-IVUS) imaging from the Improve Clinical Outcomes in high-risk patieNts with acute coronary syndrome (ICON-1). Primary endpoint was the composite of major adverse cardiovascular events (MACE) consisting of all-cause mortality, myocardial infarction (MI), and any revascularisation. Every component of MACE and target vessel failure (TVF) including MI and any revascularisation were considered as secondary endpoints. Eighty-six patients with 225 vessels undergoing VH-IVUS at baseline completed 5-year clinical follow-up. Patients with minimal lumen area (MLA) 4 demonstrated increased risk of MACE (hazard ratio [HR] 2.37, 95% confidence interval [CI] 1.00-5.59, p = 0.048) with a worse event-free survival (Log Rank 4.17, p = 0.041) than patients with MLA 4 . Patients with combination of TCFA, MLA 4 and PB 70% showed high risk of MI (HR 5.23, 95% CI 1.05-25.9, p = 0.043). Lesions with MLA 4 had 6-fold risk of TVF (HR 6.16, 95% CI 1.24-30.5, p = 0.026). Small luminal area appears as the major prognostic factor in older patients with NSTEACS at long-term follow-up. Combination of TCFA, MLA 4 and PB 70% was associated with high risk of MI. NCT01933581.
