Inflammatory Biomarkers to Predict Major Adverse Cardiovascular Events in Patients with Carotid Artery Stenosis.

Background and Objectives: Inflammatory proteins and their prognostic value in patients with carotid artery stenosis (CAS) have not been adequately studied. Herein, we identified CAS-specific biomarkers from a large pool of inflammatory proteins and assessed the ability of these biomarkers to predict adverse events in individuals with CAS. Materials and Methods: Samples of blood were prospectively obtained from 336 individuals (290 with CAS and 46 without CAS). Plasma concentrations of 29 inflammatory proteins were determined at recruitment, and the patients were followed for 24 months. The outcome of interest was a major adverse cardiovascular event (MACE; composite of stroke, myocardial infarction, or death). The differences in plasma protein concentrations between patients with vs. without a 2-year MACE were determined using the independent t-test or Mann-Whitney U test to identify CAS-specific prognostic biomarkers. Kaplan-Meier and Cox proportional hazards analyses with adjustment for baseline demographic and clinical characteristics were performed to assess the prognostic value of differentially expressed inflammatory proteins in predicting a 2-year MACE in patients with CAS. Results: The mean age of the cohort was 68.8 (SD 10.2) years and 39% were female. The plasma concentrations of two inflammatory proteins were significantly higher in individuals with a 2-year MACE relative to those without a 2-year MACE: IL-6 (5.07 (SD 4.66) vs. 3.36 (SD 4.04) pg/mL, p = 0.03) and CD163 (233.825 (SD 230.306) vs. 159.673 (SD 175.669) pg/mL, p = 0.033). Over a follow-up period of 2 years, individuals with elevated levels of IL-6 were more likely to develop MACE (HR 1.269 (95% CI 1.122-1.639), p = 0.042). Similarly, over a 2-year period, patients with high levels of CD163 were more likely to develop MACE (HR 1.413 (95% CI 1.022-1.954), p = 0.036). Conclusions: The plasma levels of inflammatory proteins IL-6 and CD163 are independently associated with adverse outcomes in individuals with CAS. These CAS-specific prognostic biomarkers may assist in the risk stratification of patients at an elevated risk of a MACE and subsequently guide further vascular evaluation, specialist referrals, and aggressive medical/surgical management, thereby improving outcomes for patients with CAS.

The Role of Family or Community Nurse in Dealing with Frail and Chronic Patients in Italy: A Scoping Review.

Even though Family and Community Nurses (FCNs) were introduced into the Italian healthcare system in 2000, to date, there is a substantial knowledge gap regarding the implementation of these professional figures within the Primary Care (PC) system. This scoping review aims to provide a comprehensive picture of the role of FCNs in managing older adults and the elderly with chronic conditions within the Italian PC system. A search on Medline, Cumulative Index to Nursing and Allied Health Literature, Cochrane Library, Embase, and Scopus was conducted including studies published until 7 April 2023. Among 141 potential articles, only 4 met our inclusion criteria. Each of these studies attributed their findings to the presence of FCNs. They reported a significant decrease in the prevalence of several behaviours among patients diagnosed with hypertension, a reduction in metabolic complications among frail patients receiving home enteral nutrition, a decline in hospital readmissions or emergency services utilization among patients >65 years of ages with at least one chronic disease, and, notably, a high level of effectiveness in detecting major cardiovascular events in patients with cardiac implantable electronic devices. Despite the effectiveness of interventions managed by FCNs, comprehensive information and research on the integration of this role within the PC setting are still lacking in the Italian healthcare system.

Clinical case of indacaterol / glycopyrronium bromide prescription in a patient with severe copd and concomitant pathology

Combinations of inhaled glucocorticosteroids (IHGC) and long-acting bronchodilator inhalers (LABA inhalers) have been widely used to treat chronic obstructive pulmonary disease (COPD) over the past two decades. Prescription of these drugs was based on large studies showing that this therapeutic regimen was more effective compared to placebo and monotherapy. The article presents a clinical case report of a patient with severe course of COPD and coronary heart disease (CHD). Up-to-date concepts of using dual bronchodilator therapy when switching from combinations of inhaled glucocorticosteroids and long-acting bronchodilator inhalers (IHGC/LABA) is discussed. A patient with COPD and coronary artery disease, atrial fibrillation while using IHGC/LABA had progressive respiratory failure, frequent exacerbations, and acute symptomatology. As there is evidence that the use of IHGC/LABA has a number of limitations in the combined course of COPD and cardiovascular diseases, first of all in coronary artery disease and arrhythmias, it was recommended to replace therapy with a combination of dual bronchodilators – a long-acting muscarinic antagonist (LAMA) and a long-acting β agonist (LABA). The therapy resulted in stabilization of the condition, reduction of clinical symptoms, and absence of cardiovascular complications. It has been concluded that the dual bronchodilator therapy with a combination of glycopyrronium bromide and indacaterol is prioritized in COPD, including COPD combined with cardiovascular pathology; no increase in cardiovascular events in patients with COPD combined with coronary artery disease is observed; Breezhaler inhaler is user-friendly for the patients and has advantages over other delivery devices.

Relationship of neutrophil-to-lymphocyte ratio, in addition to C-reactive protein, with cardiovascular events in patients with type 2 diabetes

AimTo quantify the relationship of neutrophil-to-lymphocyte ratio (NLR) with cardiovascular events and all-cause mortality in patients with type 2 diabetes (T2D), independent of C-reactive protein (CRP). MethodsPatients with T2D from the UCC-SMART-cohort were studied using multivariable-adjusted Cox regression. The relationship of NLR and CRP with vascular events (cerebrovascular events, myocardial infarction and vascular death) and all-cause mortality was quantified. ResultsDuring 10,833 person-years, 232 vascular events and 302 deaths occurred in 1,239 patients with T2D. Risk of vascular events and all-cause mortality increased per standard deviation (SD) in NLR (hazard ratio (HR) 1.27; 95 % confidence interval (CI):1.11–1.46) and 1.15; 95 % CI:1.02–1.30) after adjustment for CRP. CRP was not associated with vascular events after adjustment for NLR, (HR per SD 1.03; 95 % CI: 0.90–1.19), but was associated with all-cause mortality (HR per SD 1.18; 95 % CI: 1.04–1.33). Notably, NLR was related to vascular events in patients with CRP < 2 mg/L (HR per unit 1.45; 95 % CI: 1.19–1.77). ConclusionIn patients with T2D, NLR is related to higher risk of CVD and all-cause mortality, independently from CRP. NLR is related to CVD even when CRP is low, indicating that NLR is a marker of CVD-risk in addition to CRP. Both NLR and CRP are independently related to all-cause mortality in T2D patients.

The predictive value of lesion-specific pericoronary fat attenuation index for major adverse cardiovascular events in patients with type 2 diabetes

BackgroundThe purpose of this study was to explore the prognostic significance of the lesion-specific pericoronary fat attenuation index (FAI) in forecasting major adverse cardiovascular events (MACE) among patients with type 2 diabetes mellitus (T2DM).MethodsThis study conducted a retrospective analysis of 304 patients diagnosed with T2DM who underwent coronary computed tomography angiography (CCTA) in our hospital from December 2011 to October 2021. All participants were followed for a period exceeding three years. Detailed clinical data and CCTA imaging features were carefully recorded, encompassing lesion-specific pericoronary FAI, FAI of the three prime coronary arteries, features of high-risk plaques, and the coronary artery calcium score (CACS). The MACE included in the study comprised cardiac death, acute coronary syndrome (which encompasses unstable angina pectoris and myocardial infarction), late-phase coronary revascularization procedures, and hospital admissions prompted by heart failure.ResultsWithin the three-year follow-up, 76 patients with T2DM suffered from MACE. The lesion-specific pericoronary FAI in patients who experienced MACE was notably higher compared to those without MACE (–84.87 ± 11.36 Hounsfield Units (HU) vs. –88.65 ± 11.89 HU, p = 0.016). Multivariate Cox regression analysis revealed that CACS ≥ 100 (hazard ratio [HR] = 4.071, 95% confidence interval [CI] 2.157–7.683, p < 0.001) and lesion-specific pericoronary FAI higher than − 83.5 HU (HR = 2.400, 95% CI 1.399–4.120, p = 0.001) were independently associated with heightened risk of MACE in patients with T2DM over a three-year period. Kaplan-Meier analysis showed that patients with higher lesion-specific pericoronary FAI were more likely to develop MACE (p = 0.0023). Additionally, lesions characterized by higher lesion-specific pericoronary FAI values were found to have a greater proportion of high-risk plaques (p = 0.015). Subgroup analysis indicated that lesion-specific pericoronary FAI higher than − 83.5 HU (HR = 2.017, 95% CI 1.143–3.559, p = 0.015) was independently correlated with MACE in patients with T2DM who have moderate to severe coronary calcification. Moreover, the combination of CACS ≥ 100 and lesion-specific pericoronary FAI>-83.5 HU significantly enhanced the predictive value of MACE in patients with T2DM within 3 years.ConclusionsThe elevated lesion-specific pericoronary FAI emerged as an independent prognostic factor for MACE in patients with T2DM, inclusive of those with moderate to severe coronary artery calcification. Incorporating lesion-specific pericoronary FAI with the CACS provided incremental predictive power for MACE in patients with T2DM.

Impact of inflammation and anti-inflammatory therapies on the incidence of major cardiovascular events in patients with ankylosing spondylitis: A population-based study

ObjectiveTo examine the independent effect of inflammatory burden and various treatments on the risk of incident major adverse cardiovascular events (MACE) in ankylosing spondylitis (AS) patients. MethodsAS patients were retrospectively selected from a territory-wide database between 2006 and 2015, and were followed until the end of 2018. The primary outcome was the first occurrence of MACE. Multivariate time-varying Cox proportional hazard models were used to determine the associations between inflammatory burden (measured by c-reactive protein [CRP] and erythrocyte sedimentation rate [ESR]) and different therapies with incident MACE, after adjusting for traditional cardiovascular (CV) risk factors. ResultsA total of 3827 patients with AS (mean age: 45.2 ± 15.0 years, male: 2911 [76.1 %]) were recruited. After a follow-up of 23,275 person-years, 135 patients (3.5 %) developed a first MACE. Univariate analyses showed that elevated ESR and CRP levels, and the use of glucocorticoids were associated with a significantly higher risk of MACE, while the use of sulfasalazine (SLZ), biologic DMARDs and non-cyclooxygenase-2 inhibitors (non-COX-IIi) were associated with reduced risk of MACE. After adjusting for CV risk factors in the multivariable models, only ESR (HR: 1.02; ESR ≥30 mm/h, HR:1.94) and CRP level (HR: 1.14; CRP >3 mg/dl HR:5.43) remained significantly associated with increased risk of MACE, while SLZ use (HR: 0.41–0.52) was protective against MACE. ConclusionHigh inflammatory burden was an independent predictor associated with an increased risk of MACE, while the use of SLZ might reduce risk of incident MACE in patients with AS.

Assessment of cardiovascular risk in women with premature ovarian failure

BACKGROUND: Premature ovarian failure is a common disease that affects quality of life and cardiovascular risk in young women. AIM: To assess the relative risk of cardiovascular events in patients with primary and secondary premature ovarian failure. MATERIAL AND METHODS: The study included three groups of patients comparable in age: the first — women with primary premature ovarian failure at the age of 39.8±4.3 years; the second — women with secondary premature ovarian failure, age 40.1±4.1 years; the third was the control group at the age of 40.3±3.9 years, there were 133 people in each group. The cardiovascular profile (smoking status, metabolic health, lipid profile, glucose level, blood pressure, pulse and cardiovascular history) of patients with premature ovarian failure was analyzed. Identification of relationships between the studied signs (increase in waist circumference, increase in systolic blood pressure 140 mm Hg, increase in diastolic blood pressure 90 mm Hg, dyslipidemia, arterial hypertension, arrhythmia, coronary heart disease, diabetes mellitus, metabolic syndrome) carried out by calculating the odds ratio and relative risk. The 10-year risk of developing cardiovascular diseases was also calculated using the SCORE2 scale. RESULTS: Patients with both primary and secondary premature ovarian failure had a higher relative risk of developing cardiovascular events compared with healthy women. The 10-year risk of developing cardiovascular events according to the SCORE2 scale was statistically significantly increased in women with premature ovarian failure compared to the control group. In patients with primary failure it was 9.4% (confidence interval 6–14%; p=0.018), in patients with secondary failure — 7.6% (confidence interval 4–14%; p=0.023), and in the control group — 5.1% (confidence interval 3–14%; p=0.039). CONCLUSION: Patients with premature ovarian failure have a higher cardiovascular risk compared to a group of healthy women.

Cardiovascular events in patients receiving immuno-oncology agents, in phase I clinical trials: CAVIO study.

e24009 Background: Among immunoncology agents (IO), immune checkpoint inhibitors are the most used, demonstrating survival benefit across multiple cancer types. Adverse events are often reported with IO; cardiotoxicity is rare, but potentially fatal. CAVIO study evaluated the occurrence of cardiovascular events (CVE) in patients receiving IO in phase I clinical trials (ph1CT). Methods: We retrospectively reviewed clinical and cardiological data of patients consecutively enrolled, from Jan2016 to Dec2021, in ph1CT with IO alone or in combination. Any type and grade of CVE occurred on treatment, related or not to IO, was evaluated. Fisher’s exact tests were used to compare variables. Cox regression and Kaplan Meier methods were used for multivariable analyses and estimating overall survival (OS). Hazard ratio (HR) and 95% confident interval (CI) were calculated. Results: 211 patients were included; median age was 57 years. The most frequent site of primary tumor was breast (25%). 43 of 211 patients experienced ≥1 CVE of any grade (G) during the treatment, of which &lt; 1% G3 and none ³G4. The most frequent ones were hypertension (n = 20, 9%) and thrombosis (n = 15, 7%), only one myocarditis (2%). Table 1 shows the significant differences observed between patients experiencing CVE or not. The occurrence of CVE was not associated with pre-existing cardiovascular risk factors nor with number of prior therapy lines. The median progression free survival (mPFS) and mOS were 2 and 9 months respectively, regardless the CVE occurrence. Patients using anticoagulant at the end of ph1CT showed worse PFS and OS (1.8 and 5.4m) than those who did not (2.5 and 11.1m), similarly was for PS ECOG 1 vs 0. The result was consistent at the multivariate model adjusted for the primary site of tumor, PS ECOG, previous lines of treatment and age, in which PS ECOG 1 and the use of anticoagulant remained statistically significant associated with negative OS (for PSECOG: HR:1.84, 95% CI 1.31-2.57, p &lt; 0.001; for anticoagulant use: HR: 1.72, 95%CI:1.20-2.47, p:0.003). Conclusions: The occurrence of CVE did not change the outcomes of patients treated with IO in ph1RC. Severe CVE were rare, hypertension being the most frequent. Further data are needed on the correlation of anticoagulant use, IO and patients prognosis. [Table: see text]

Predictive Effect of Alternative Insulin Resistance Indexes on Adverse Cardiovascular Events in Patients with Metabolic Syndrome with Heart Failure.

Metabolic Syndrome (MS) greatly increases the risk of heart disease and Heart Failure(HF). Insulin Resistance (IR) is considered to be the key to the pathophysiology of MS. The purpose of this study was to evaluate the predictive effect of different alternative indicators of IR on adverse cardiovascular events in patients with MS complicated with HF. Patients with HF who were diagnosed with MS in the heart center of the first affiliated Hospital of Xinjiang Medical University were selected continuously. The baseline data of the patients in the group were compared. The diagnostic value of alternative indexes of IR was evaluated by the working characteristic curve of subjects. The relationship between different alternative indicators of IR and survival rate was evaluated by survival curve. COX regression was used to analyze the effects of different alternative indicators of IR on the risk of end-point events. The levels of TyG, TyG-BMI, TyG-WC, TG/HDL-C and METS-IR were significantly increased in patients with Major Adverse Cardiovascular Events (MACEs). Among the five alternative indexes of IR, METS-IR had the highest AUC (0.691, 95% CI:0.657-0.752, P < 0.001) in predicting MACEs. No matter which alternative index of IR was used, the survival rate of MACEs in High group was significantly decreased. TyG, TyG-BMI, TyG-WC, TG/HDL-C and METS-IR can independently predict the occurrence of MACEs events, even if some confounding factors are adjusted. Our study shows that alternative indicators of IR, especially METS-IR, are independently associated with adverse cardiovascular events in patients with MS and HF.

PCSK9 Inhibitor Added to High-Intensity Statin Therapy to Prevent Cardiovascular Events in Patients with Acute Coronary Syndrome after Percutaneous Coronary Intervention: A Randomized, Double- Blind, Placebo-Controlled, Multicenter SHAWN Study

BackgroundIt is currently uncertain whether the combination of a proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor and high-intensity statin treatment can effectively reduce cardiovascular events in patients with acute coronary syndrome (ACS) who have undergone percutaneous coronary intervention (PCI) for culprit lesions. MethodsThis study protocol describes a double-blind, randomized, placebo-controlled, multicenter study aiming to investigate the efficacy and safety of combining a PCSK9 inhibitor with high-intensity statin therapy in patients with ACS following PCI. A total of 1212 patients with ACS and multiple lesions will be enrolled and randomly assigned to receive either PCSK9 inhibitor plus high-intensity statin therapy or high-intensity statin monotherapy. The randomization process will be stratified by sites, diabetes, initial presentation and use of stable (≥4 weeks) statin treatment at presentation. PCSK 9 inhibitor or its placebo is injected within 4 hours after PCI for the culprit lesion. The primary endpoint is the composite of cardiovascular death, myocardial infarction, stroke, re-hospitalization due to ACS or heart failure, or any ischemia-driven coronary revascularization at one-year follow-up between two groups. Safety endpoints mean PCSK 9 inhibitor and statin intolerance. ConclusionThe SHAWN study has been specifically designed to evaluate the effectiveness and safety of adding a PCSK9 inhibitor to high-intensity statin therapy in patients who have experienced ACS following PCI. The primary objective of this study is to generate new evidence regarding the potential benefits of combining a PCSK9 inhibitor with high-intensity statin treatment in reducing cardiovascular events among these patients.

Deaths and major cardiovascular events in patients with lymphoma: Analysis from a French nationwide hospitalization database

BackgroundThere are few data assessing the risk of death and cardiovascular events in patients with lymphoma. AimUsing a nationwide hospitalization database, we aimed to address cardiovascular outcomes in patients with lymphoma. MethodsFrom 01 January to 31 December 2013, 3,381,472 adults were hospitalized in French hospitals; 22,544 of these patients had a lymphoma. The outcome analysis (all-cause or cardiovascular death, myocardial infarction, ischaemic stroke, bleedings, new-onset heart failure and new-onset atrial fibrillation) was performed over a 5-year follow-up period. Each patient with lymphoma was matched with a patient without a lymphoma or other cancer (1:1). A competing risk analysis was also performed. ResultsAfter adjustment on all risk factors, cardiovascular and non-cardiovascular co-morbidities, the subdistribution hazard ratios for all-cause death, major bleeding, intracranial bleeding, new-onset heart failure and new-onset atrial fibrillation were higher in patients with lymphoma; conversely, the subdistribution hazard ratios for cardiovascular death, myocardial infarction and ischaemic stroke were lower in patients with lymphoma. In the matched analysis, the risk of all-cause death (subdistribution hazard ratio 1.936, 95% confidence interval 1.881–1.992) and major bleeding (subdistribution hazard ratio 1.117, 95% confidence interval 1.049–1.188) remained higher in patients with lymphoma. ConclusionIn this large nationwide cohort study, patients with lymphoma had a higher incidence of all-cause death and major bleeding.

Risk Stratification Using Right Ventricular Longitudinal Strain Ratio Derived from 13N-Ammonia PET in Patients with Ischemic Heart Disease.

Purpose To investigate whether right ventricular (RV) myocardial strain ratio (RVMSR) assessed using nitrogen 13 ammonia (13N-NH3) PET can predict cardiovascular events in patients with ischemic heart disease (IHD). Materials and Methods This retrospective study included 480 consecutive patients (mean age, 66 years ± 12 [SD]; 334 males and 146 females) with IHD who underwent 13N-NH3 PET. RVMSR was defined as the ratio of RV strain during stress to that at rest. The primary end point was major adverse cardiac events (MACEs), defined as cardiac death or heart failure hospitalization. The ability of RVMSR to predict MACE was assessed using receiver operating characteristic (ROC) curve and Kaplan-Meier analyses. Cox proportional hazards regression analysis was used to calculate hazard ratios (HRs) with 95% CIs. Results ROC curve analysis identified a sensitivity and specificity of 84% and 82%, respectively, for predicting MACE from RVMSR. Patients with reduced RVMSR (<110.2) displayed a significantly higher rate of MACE than those with a preserved RVMSR (34 of 240 vs four of 240; P < .001). Cox proportional hazards regression analysis of imaging parameters, including myocardial flow reserve, indicated that RVMSR was an independent predictor of MACE (HR, 0.94 [95% CI: 0.92, 0.97]; P < .001). Conclusion RVMSR was an independent predictor of MACE and has potential to aid in the risk stratification of patients with IHD.

Cardiovascular complications associated with asciminib use: A retrospective analysis.

6563 Background: Asciminib, a newly developed drug, has shown promising results in the treatment of several diseases. It is a cellular tyrosine kinase inhibitor (TKI) that specifically targets ABL myristoyl pocket (STAMP) inhibitor, responsible for the malignant growth and proliferation of leukemia cells in chronic myeloid leukemia (CML) patients, assuring a positive treatment of CML. However, as with all medications, there are possible side effects that must be carefully monitored. In comparison to Ponatinib (tyrosine kinase inhibitor) which is extensively used to treat CML and exhibits a cardiovascular risk profile, cardiovascular side effects with the use of Asciminib are rarely reported in literature, prompting its use in patients at a higher risk of these events. Through this study, we aim to highlight the cardiovascular complications associated with the use of Asciminib by integrating patient experience and clinical research. Methods: A publicly available FDA Adverse Events Reporting System (FAERS) database was utilized to review cardiovascular events associated with the use of Asciminib in patients with Chronic Myeloid leukemia (CML) between 2018-2023. Cardiovascular events such as coronary artery disease (CAD), peripheral arterial disease (PAD), and cerebrovascular accidents (CVA) were reviewed. The study focused only on adverse events reported by healthcare providers and observed in adults (above 18 years old). Results: We identified a total of 563 adverse events pertaining to the use of Asciminib in patients with CML. Of which, 63 were cardiovascular events, contributing to 11.2% of the total adverse events. Out of the reported cardiovascular side effects, 29 (46%) were due to CAD, 6 (9.5%) were due to PAD, and 28 (44.45%) were due to CVA. The mortality rate amongst patients who experienced cardiovascular side effects was 11%. Moreover, cardiovascular events contributed to 7% of all mortality associated with the use of Asciminib, with CAD contributing to most of the deaths. Conclusions: It is imperative to consider the potential of cardiovascular events in patients initiated on Asciminib. This study emphasizes the importance of using patient records and medical research to obtain complete information. Patients with underlying risk factors for the development of cardiovascular diseases should be thoroughly evaluated before drug initiation. The minimum threshold for drug discontinuation should be considered in patients with suspected heart disease.

Evaluation of ivabradine plus beta-blocker versus beta-blocker alone in addition to standard care in reducing hospitalization and major adverse cardiovascular event in patients with chronic heart failure: a prospective observational study in tertiary care hospital in central India

BackgroundIn recent years, there has been an increase in cases of heart failure, ultimately leading to an increase in hospitalization for heart failure (HF) and cardiovascular mortality. The aim of our study was to evaluate ivabradine combined with beta-blocker versus beta-blocker alone in addition to standard care for chronic heart failure, followed for a period of 6 months for the rate of hospitalization and major adverse cardiovascular event (MACE) in patients with reduced left ventricular ejection fraction (LVEF < 35%).ResultsA total of 64 patients were included in this observational study with 30 patients in the ivabradine + beta-blocker (IVA + BB) group and 34 in the beta-blocker (BB) group. The median (IQR) age of the study sample was 57 (50–62) and 58.5 (55–67) in IVA + BB and BB groups, respectively, with LVEF < 35%. The incidence of the primary endpoint of composite MACE (MI, stroke, death, worsening of HF) was 5 in both groups. The mean heart rate was significantly decreased (p < 0.001) at 3-month and 6-month follow-up from baseline in the ivabradine + beta-blocker group as compared to the beta-blocker group alone, while it significantly increased in the beta-blocker group at 3 months (p < 0.01) and also at sixth months (p < 0.05). Parameters such as the New York Heart Association (NYHA) class and the Minnesota Living with Heart Failure questionnaire (MLWHFQ) were also assessed but did not show significant change.ConclusionOverall, observations from the study results show that IVA + BB seems to be overall well tolerated in the study sample, with a somewhat smaller decrease in hospitalization and a delay in MACE events in the sample population enrolled in a tertiary care hospital in India. Further exploration in a larger sample is required concerning the Indian population.

Effects of Smoking on Major Adverse Cardiovascular Events in Patients With Coronary Artery Spasm: A Systematic Review and Meta-Analysis

Smoking is an established independent risk factor for coronary artery spasm (CAS), but its effects on major adverse cardiovascular events (MACE) in patients with CAS have not been systematically assessed. This systematic review and meta-analysis of studies published from January 2000 to July 2023 was conducted to examine the relationship between smoking and MACE in patients with CAS. Data on MACE were obtained from both smoking and non-smoking CAS patient groups. The effects of smoking on MACE in patients with CAS were assessed through meta-analysis, utilising Stata 17.0 software for all statistical analyses. Nine studies, encompassing 9,376 patients, from Japan (5 studies), Korea (4 studies) and Spain (1 study) were included in the final analysis. Meta-analysis revealed that smoking significantly impacted MACE in patients with CAS (RR 1.965; 95% CI 1.348-2.865), a finding further validated by sensitivity analyses. Subgroup analyses identified a stronger correlation between smoking and increased MACE endpoints in Japanese patients and in those with >3 years of follow-up. This meta-analysis strongly indicates that smoking escalates the risk of MACE in patients with CAS, with a more pronounced association observed in Japanese patients and those with extended follow-up periods.

Inflammatory risk and cardiovascular events in patients without obstructive coronary artery disease: the ORFAN multicentre, longitudinal cohort study

Coronary computed tomography angiography (CCTA) is the first line investigation for chest pain, and it is used to guide revascularisation. However, the widespread adoption of CCTA has revealed a large group of individuals without obstructive coronary artery disease (CAD), with unclear prognosis and management. Measurement of coronary inflammation from CCTA using the perivascular fat attenuation index (FAI) Score could enable cardiovascular risk prediction and guide the management of individuals without obstructive CAD. The Oxford Risk Factors And Non-invasive imaging (ORFAN) study aimed to evaluate the risk profile and event rates among patients undergoing CCTA as part of routine clinical care in the UK National Health Service (NHS); to test the hypothesis that coronary arterial inflammation drives cardiac mortality or major adverse cardiac events (MACE) in patients with or without CAD; and to externally validate the performance of the previously trained artificial intelligence (AI)-Risk prognostic algorithm and the related AI-Risk classification system in a UK population. This multicentre, longitudinal cohort study included 40 091 consecutive patients undergoing clinically indicated CCTA in eight UK hospitals, who were followed up for MACE (ie, myocardial infarction, new onset heart failure, or cardiac death) for a median of 2·7 years (IQR 1·4-5·3). The prognostic value of FAI Score in the presence and absence of obstructive CAD was evaluated in 3393 consecutive patients from the two hospitals with the longest follow-up (7·7 years [6·4-9·1]). An AI-enhanced cardiac risk prediction algorithm, which integrates FAI Score, coronary plaque metrics, and clinical risk factors, was then evaluated in this population. In the 2·7 year median follow-up period, patients without obstructive CAD (32 533 [81·1%] of 40 091) accounted for 2857 (66·3%) of the 4307 total MACE and 1118 (63·7%) of the 1754 total cardiac deaths in the whole of Cohort A. Increased FAI Score in all the three coronary arteries had an additive impact on the risk for cardiac mortality (hazard ratio [HR] 29·8 [95% CI 13·9-63·9], p<0·001) or MACE (12·6 [8·5-18·6], p<0·001) comparing three vessels with an FAI Score in the top versus bottom quartile for each artery. FAI Score in any coronary artery predicted cardiac mortality and MACE independently from cardiovascular risk factors and the presence or extent of CAD. The AI-Risk classification was positively associated with cardiac mortality (6·75 [5·17-8·82], p<0·001, for very high risk vs low or medium risk) and MACE (4·68 [3·93-5·57], p<0·001 for very high risk vs low or medium risk). Finally, the AI-Risk model was well calibrated against true events. The FAI Score captures inflammatory risk beyond the current clinical risk stratification and CCTA interpretation, particularly among patients without obstructive CAD. The AI-Risk integrates this information in a prognostic algorithm, which could be used as an alternative to traditional risk factor-based risk calculators.

Circulating levels of amyloid-beta (1-40) peptide associate with cardiometabolic traits and risk for metabolic dysfunction-associated steatotic liver disease

Abstract Funding Acknowledgements None. Background and Aims The ageing-associated amyloid-beta 1-40 peptide (Αbeta40) has recently emerged as a blood-based biomarker of cardiovascular disease (CVD). Its levels predict future cardiovascular death and major adverse cardiovascular events in patients with established CVD. The value of Abeta40 in patients with metabolic syndrome who do not concomitantly have clinically overt CVD or other end-organ damage remains poorly understood. At the present study we investigated the value of plasma Αbeta40 in patients with pre- or established metabolic syndrome who are at risk for metabolic dysfunction-associated steatotic liver disease (MASLD). Methods Αbeta40 was measured in plasma by enzyme-linked immunosorbent assay and cardiometabolic traits were determined in a mixed population (n=888) of patients with established (n=243) and pre- or without metabolic syndrome (n=645) who did not have clinical signs of established cardiometabolic disease. The endpoint of the study was the association of Abeta40 with cardiometabolic indices and risk (BARD score) for MASLD. Odds ratio (OR) was calculated by ordinal regression analysis for the increasing incidence of metabolic syndrome components per increasing Abeta40 (1-SD) after adjustment for age, sex, smoking status and hyperlipidemia. Results Abeta40 levels are associated with the presence of metabolic syndrome and with higher odds for increasing incidence of metabolic syndrome components (prediabetes, low HDL-C levels, high triglyceride levels, increased waist circumference and high-risk for MASLD) after adjustment for sex, age, smoking status, hypertension and dyslipidemia. Increased Abeta40 plasma levels were associated with decreased HDL-C levels and increased triglyceride levels after adjustment for traditional cardiovascular risk factors (age, sex, smoking status, hypertension and hyperlipidemia). Among the total population (n=888), we identified n=473 subjects with increased MASLD risk if any of the following was present: hepatic steatosis index≥36 or fatty liver index≥60 or Fib-4 index≥2.67 or NAFLD score≥0.675. Among patients with high-risk for MASLD, patients with increased BARD score had significantly higher Abeta40 levels (median Abeta40 concentration in patients with BARD score≥2 vs. patients with BARD score&amp;lt;2: 54.9 pg/ml (IQR=38.25) vs. 41.9 pg/m (IQR=30.35), P=0.012). Increased Abeta40 levels were associated with increased odds for AST/ALT≥0.8 ratio (OR:1.017, 95% CI: 1.006-1.028, P=0.003) and increased odds for BARD score≥2 after adjustment for age, sex, smoking status, hypertension and hyperlipidemia. Conclusion Our findings suggest that Abeta40 peptide is associated with cardiometabolic traits and risk for MASLD. Whether Abeta40 may emerge as an early cardiometabolic prognostic biomarker, future longitudinal studies are warranted to determine the prognostic value of Abeta40 for the development of cardiometabolic diseases in patients with metabolic syndrome.
