Increased Prevalence of Diastolic Heart Failure in Patients with Rheumatoid Arthritis Correlates with Active Disease, but Not with Treatment Type

Biologics or Janus Kinase Inhibitors in Rheumatoid Arthritis Patients Who are Insufficient Responders to Conventional Anti-Rheumatic Drugs

Rheumatoid arthritis (RA) is a chronic immune-mediated inflammatory disease which can induce progressive disability if not properly treated early. Over the last 20 years, the improvement of knowledge on the pathogenesis of the disease has made available several drugs targeting key elements of the pathogenetic process, which now represent the preferred treatment option after the failure of first-line therapy with conventional drugs such as methotrexate (MTX). To this category of targeted drugs belong anti-cytokine or cell-targeted biological agents and more recently also Janus kinase inhibitors (JAKis). In the absence to date of specific biomarkers to guide the therapeutic choice in the context of true precision medicine, the choice of the first targeted drug after MTX failure is guided by treatment cost (especially after the marketing of biosimilar products) and by the clinical characteristics of the patient (age, sex, comorbidities and compliance) and the disease (presence or absence of autoantibodies and systemic or extra-articular manifestations), which may influence the efficacy and safety profile of the available products. This viewpoint focuses on the decision-making process underlying the personalized approach to RA therapy and will analyse the evidence in the literature supporting the choice of individual products and in particular the differential choice between biological drugs and JAKis.

The importance of speckle tracking echocardiography in the evaluation of cardiac functions in patients with rheumatoid arthritis

Objectives

In this study, we aimed to analyze the layer-specific strain values obtained by speckle tracking echocardiography (STE) method in the determination of subclinical cardiac dysfunction in rheumatoid arthritis (RA) patients.

Patients and methods

Between February 2019 and October 2019, a total of 63 female RA patients (mean age: 51.82±6.07 years; range, 40 and 65 years) who had a confirmed diagnosis were included. Thirty-one age-matched female healthy individuals (mean age: 50.71±5.37 years; range, 40 and 65 years) were selected as the control group. The patients were divided into three groups according to the duration of disease as <5 years, 5-10 years and >10 years. The Disease Activity Score in 28 joint - C-reactive protein (CRP) was used to determine disease activation. The standard assessment included complete serum CRP, anti-cyclic citrullinated peptide, rheumatoid factor, N-terminal pro B-type natriuretic peptide (NT-proBNP), and homocysteine. Global longitudinal strain (GLS) analysis was performed with STE.

Results

The NT-proBNP values were found to be higher in RA patients compared to the control group (p=0.044). In terms of conventional echocardiographic parameters, a significant difference between E/A and E/E' ratios was observed (p<0.001 and p=0.015). Endocardium, transmural, and epicardium GLS values obtained by STE were found to be lower in RA patients (p<0.05). The left ventricular (LV) GLS values worsened, as the duration of disease increased (p<0.05). There was a significant correlation between RA disease activity and LV GLS values, showing that increasing levels of disease activity was associated with worse LV GLS (r=0.583, p<0.01 and r=0.681, p<0.01 and r=0.689, p<0.01 for endocardium, transmural and epicardium, respectively).

Conclusion

Our study results suggest that the layer-specific GLS values obtained by STE decrease in RA patients.

Rheumatoid arthritis increases the risk of heart failure: results from the cross-sectional study in the US population and mendelian randomization analysis in the European population

Objective

Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease. Among its various complications, heart failure (HF) has been recognized as the second leading cause of cardiovascular death in RA patients. The objective of this study was to investigate the relationship between RA and HF using epidemiological and genetic approaches.

Methods

The study included 37,736 participants from the 1999-2020 National Health and Nutrition Examination Survey. Associations between RA and HF in the US population were assessed with weighted multivariate logistic regression analysis. A two-sample Mendelian randomization (MR) analysis was employed to establish the causal relationship between the two variables. The primary analysis method utilized was inverse variance weighting (IVW). Additionally, horizontal pleiotropy and heterogeneity were assessed to account for potential confounding factors. In cases where multiple independent datasets were accessible during MR analysis, we combined the findings through a meta-analytical approach.

Results

In observational studies, the prevalence of HF in combination with RA reached 7.11% (95%CI 5.83 to 8.39). RA was positively associated with an increased prevalence of HF in the US population [odds ratio (OR):1.93, 95% confidence interval (CI):1.47-2.54, P < 0.0001]. In a MR analysis utilizing a meta-analytical approach to amalgamate the results of the IVW method, we identified a significant causal link between genetically predicted RA and a heightened risk of HF (OR = 1.083, 95% CI: 1.028-1.141; P = 0.003). However, this association was not deemed significant for seronegative RA (SRA) (OR = 1.028, 95% CI: 0.992-1.065; P = 0.126). These findings were consistent across sensitivity analyses and did not indicate any horizontal pleiotropy.

Conclusion

RA correlates with an elevated prevalence of HF within the US population. Furthermore, genetic evidence derived from European populations underscores a causal link between RA and the risk of HF. However this association was not significant in SRA.

Tumor Necrosis Factor Alpha Inhibitors and Cardiovascular Risk in Rheumatoid Arthritis

Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by an increased risk of cardiovascular events, due to the complex interplay between traditional and disease-related risk factors. Chronic inflammation and persistent disease activity are the key determinants of this risk, but despite great improvement in the disease management and prognosis, cardiovascular events are still the main cause of morbidity and mortality in RA cohorts1. In the last decades, the advent of new biological and targeted-synthetic DMARDs was accompanied by an improvement in disease activity control, but the role of each class of drugs on CVD risk is still a matter a debate. Since their approval for RA treatment, tumor necrosis factor alpha (TNFα) inhibitors have been widely investigated to better understand their effects on cardiovascular outcomes. The hypothesis that the reduction of chronic inflammation with any treatment may reduce the cardiovascular risk has been recently confuted by the direct comparison of TNFα-inhibitors and JAK inhibitors in patients with RA and coexisting risk factors for cardiovascular disease. The aim of this literature review is to add to the available evidence to analyze the relationship between TNFα-inhibitors and CVD risk in patients with RA and also provide some clinical scenarios to better explain the treatment dilemmas. In particular, while data on major cardiovascular events and thromboembolism seem consistent with an inflammation-mediated benefit with TNFα-inhibitors, there remain concerns about the use of this class of bDMARDs in patients with chronic heart failure.

Association Between Inflammation, Incident Heart Failure, and Heart Failure Subtypes in Patients With Rheumatoid Arthritis

OBJECTIVE

In rheumatoid arthritis (RA), there are limited data on risk factors for the clinical heart failure (HF) subtypes of HF with reduced ejection fraction (HFrEF) and HF with preserved ejection fraction (HFpEF). This study examined the association between inflammation and incident HF subtypes in RA. Because inflammation changes over time with disease activity, we hypothesized that the effect of inflammation may be stronger at the 5-year follow-up than at the standard 10-year follow-up from general population studies of cardiovascular risk.

METHODS

We studied an electronic health record (EHR)-based RA cohort with data pre- and post-RA incidence. We applied a validated approach to identify HF and extract ejection fraction to classify HFrEF and HFpEF. Follow-up started from the RA incidence date (index date) to the earliest occurrence of incident HF, death, last EHR encounter, or 10 years. Baseline inflammation was assessed using erythrocyte sedimentation rate or C-reactive protein values. Covariates included demographic characteristics, established HF risk factors, and RA-related factors. We tested the association between baseline inflammation with incident HF and its subtypes using Cox proportional hazards models.

RESULTS

We studied 9,087 patients with RA; 8.2% developed HF during 10 years of follow-up. Elevated inflammation was associated with increased risk for HF at both 5- and 10-year follow-ups (hazard ratio [HR] 1.66, 95% confidence interval [95% CI] 1.12-2.46 and HR 1.46, 95% CI 1.13-1.90, respectively), which is also seen for HFpEF at 5 years (HR 1.72, 95% CI 1.09-2.70) and 10 years (HR 1.45, 95% CI 1.07-1.94). HFrEF was not associated with inflammation for either follow-up time.

CONCLUSION

Elevated inflammation early in RA diagnosis was associated with HF; this association was driven by HFpEF and not HFrEF, suggesting a window of opportunity for prevention of HFpEF in RA.

Subclinical left ventricular dysfunction and N-terminal pro-brain natriuretic peptide in patients with rheumatoid arthritis

Aim – to determine the frequency of myocardial dysfunction using echocardiography with speckle tracking (STE) method, the relationship between a low global longitudinal strain (GLS) with the level of NT-proBNP, clinical and laboratory manifestations of rheumatoid arthritis. Material and methods. The study included 43 patients with RA (ACR/EULAR criteria, 2010): 79% women, age – 53.0 [38.0; 63.0] years, disease duration – 60.0 [36; 180] months; DAS28 – 5.9 [5.2; 6.4], positive for ACCP (74%), RF IgM (81%), without prior biological therapy and CVD. Methotrexate was received by 44%, leflunomide – 35%, sulfasalazine – 9.3%, hydroxychloroquine – 7%, glucocorticoids – 67.4%, non-steroidal anti-inflammatory drugs – 74% of patients with RA. All RA patients underwent echocardiography – tissue Doppler and STE. The level of NT-proBNP was determined in the blood serum The normal range for NT-proBNP was less than 125 pg/ml.

Results. Low GLS was observed in 26 (61%) patients with RA. RA patients had a decrease GLS, E LV, E’ LV, E/A LV compared with the control group. Left ventricular diastolic dysfunction (LVDD) was higher in RA patients (13 (31%) vs 0%). Patients with RA had significantly higher levels of NT-proBNP (114.8 [45.1; 277.5] and 52 [40.5; 69.1] pg/ml) compared with the control group. There were correlations between a low GLS and DAS28 (r=0.9), the number of painful joints (r=0.6), radiological stage (r=0.6) and the presence of systemic manifestations (r=0.5), age (r=–0.9), E LV velocity (r=–0.5) (p<0.05 in all cases). There were correlations between the level of NT-proBNP and the E/A LV ratio (r=–0.4), A LV velocity (r=0.5) (p><0.05 in all cases).>< 0.05 in all cases). There were correlations between the level of NT-proBNP and the E/A LV ratio (r=–0.4), A LV velocity (r=0.5) (p< 0.05 in all cases).

Conclusions. In RA patients with a high frequency the low GLS LV was detected, which is associated with a high activity of the inflammatory process. STE helps to detect myocardial dysfunction in patients with RA at earlier stages than tissue Doppler. The use of STE, the determination of the level of NT-proBNP make it possible to diagnosing preclinical disorders of systolic and diastolic functions of the LV, which can contribute to the early initiation of therapy and improve the prognosis in this category of patients.

The prevalence of comorbidity in rheumatoid arthritis: a systematic review and meta-analysis

This systematic review and meta-analysis estimates the prevalence of common comorbid health disorders in adults with rheumatoid arthritis (RA). A multi-database search strategy was undertaken. Screening, data extraction and quality assessment were carried out by two independent reviewers. A meta-analysis and meta-regression were used to generate a pooled prevalence estimate and identify relevant moderators. After study selection, 33 studies (74633 participants) were included in the meta-analysis. Some 31 studies were judged to be of low risk of bias, and two studies were judged to be at moderate risk of bias. The three most common comorbidities in RA were anxiety disorders (62.1%, 95% Cl: 43.6%; 80.6%), hypertension (37.7%, 95% Cl: 29.2%; 46.2%) and depression (32.1%, 95% Cl: 21.6%; 42.7%). There was substantial statistically significant heterogeneity for all comorbidities (I2 ≥77%). Meta-regression identified that the covariate of mean age (unit increase) had a statistically significant effect on the prevalence of hypertension (+2.3%, 95% Cl: 0.4%; 4.2%), depression (-0.5%, 95% Cl: -0.6%; -0.4%) and cancer (0.5%, 95% Cl: 0.2%; 0.8%) in adults with RA. A country's income was identified to have a statistically significant effect on the prevalence of depression, with low-to moderate-income countries having 40% (95% Cl: 14.0%; 66.6%) higher prevalence than high-income countries. No studies consider health inequalities. It is concluded that comorbidities are prevalent among people with RA, particularly those associated with mental health and circulatory conditions. Provision of health services should reflect the importance of such multimorbidity and the consequences for quality and length of life.

Myocardial Dysfunction and Heart Failure in Rheumatoid Arthritis

Rheumatoid arthritis (RA) patients have almost twice the risk of heart failure (HF) as individuals without RA, even with adjustment for the presence of ischemic heart disease. Moreover, RA patients remain at a 2-fold higher risk of mortality from HF compared to non-RA patients. These observations suggest that RA-specific inflammatory pathways are significant contributors to this increased risk of HF. Herein we summarize the epidemiology of HF in RA patients, the differences in myocardial structure or function between RA patients and non-RA patients without clinical signs of HF, and data on the role of systemic and local inflammation in RA HF pathophysiology. We also discuss the impact of subduing inflammation through the use of RA disease-modifying therapies on HF and myocardial structure and function, emphasizing gaps in the literature and areas needing further research.

Impact of delayed type hypersensitivity arthritis on development of heart failure by aortic constriction in mice

Aims

Patients with rheumatoid arthritis (RA) have increased risk of heart failure (HF). The mechanisms and cardiac prerequisites explaining this association remain unresolved. In this study, we sought to determine the potential cardiac impact of an experimental model of RA in mice subjected to HF by constriction of the ascending aorta.

Methods

Aorta was constricted via thoracotomy and placement of o-rings with inner diameter 0.55 mm or 0.66 mm, or sham operated. RA-like phenotype was instigated by delayed-type hypersensitivity arthritis (DTHA) two weeks after surgery and re-iterated after additional 18 days. Cardiac magnetic resonance imaging (MRI) was performed before surgery and at successive time points throughout the study. Six weeks after surgery the mice were euthanized, blood and tissue were collected, organ weights were documented, and expression levels of cardiac foetal genes were analysed. In a supplemental study, DTHA-mice were euthanized throughout 14 days after induction of arthritis, and blood was analysed for important markers and mediators of RA (SAP, TNF-α and IL-6). In order to put the latter findings into clinical context, the same molecules were analysed in serum from untreated RA patients and compared to healthy controls.

Results

Significant elevations of inflammatory markers were found in both patient- and murine blood. Furthermore, the DTHA model appeared clinically relevant when compared to the inflammatory responses observed in three prespecified RA severity disease states. Two distinct trajectories of cardiac dysfunction and HF development were found using the two o-ring sizes. These differences were consistent by both MRI, organ weights and cardiac foetal gene expression levels. Still, no difference within the HF groups, nor within the sham groups, could be found when DTHA was induced.

Conclusion

DTHA mediated systemic inflammation did not cause, nor modify HF caused by aortic constriction. This indicates other prerequisites for RA-induced cardiac dysfunction.

Biologics in Psoriasis: Updated Perspectives on Long-Term Safety and Risk Management

Biologics targeting Th1/Th17 cytokines have revolutionised psoriasis treatment. In addition to treatment effectiveness, it is important to define and understand the long-term risks of biologic therapy in order to guide therapy selection and minimise these risks for patients where possible. This review article summarises available evidence from trial data, observational studies and pharmacovigilance registries to explore key long-term risks of biologic treatment, and how these risks might be managed in clinical practice.

Autoimmune Rheumatic Diseases and Vascular Function: The Concept of Autoimmune Atherosclerosis

Autoimmune rheumatic diseases (AIRDs) with unknown etiology are increasing in incidence and prevalence. Up to 5% of the population is affected. AIRDs include rheumatoid arthritis, system lupus erythematosus, systemic sclerosis, and Sjögren's syndrome. In patients with autoimmune diseases, the immune system attacks structures of its own body, leading to widespread tissue and organ damage, which, in turn, is associated with increased morbidity and mortality. One third of the mortality associated with autoimmune diseases is due to cardiovascular diseases. Atherosclerosis is considered the main underlying cause of cardiovascular diseases. Currently, because of finding macrophages and lymphocytes at the atheroma, atherosclerosis is considered a chronic immune-inflammatory disease. In active inflammation, the liberation of inflammatory mediators such as tumor necrotic factor alpha (TNFa), interleukine-6 (IL-6), IL-1 and other factors like T and B cells, play a major role in the atheroma formation. In addition, antioxidized, low-density lipoprotein (LDL) antibodies, antinuclear antibodies (ANA), and rheumatoid factor (RF) are higher in the atherosclerotic patients. Traditional risk factors like gender, age, hypercholesterolemia, smoking, diabetes mellitus, and hypertension, however, do not alone explain the risk of atherosclerosis present in autoimmune diseases. This review examines the role of chronic inflammation in the etiology-and progression-of atherosclerosis in autoimmune rheumatic diseases. In addition, discussed here in detail are the possible effects of autoimmune rheumatic diseases that can affect vascular function. We present here the current findings from studies that assessed vascular function changes using state-of-the-art techniques and innovative endothelial function biomarkers.

Annexin A1 attenuates cardiac diastolic dysfunction in mice with inflammatory arthritis

Rheumatoid arthritis (RA) carries a twofold increased incidence of heart failure with preserved ejection fraction, accompanied by diastolic dysfunction, which can lead to death. The causes of diastolic dysfunction are unknown, and there are currently no well-characterized animal models for studying these mechanisms. Current medications for RA do not have marked beneficial cardio-protective effects. K/BxN F1 progeny and KRN control mice were analyzed over time for arthritis development, monitoring left ventricular diastolic and systolic function using echocardiography. Excised hearts were analyzed by flow cytometry, qPCR, and histology. In pharmacological experiments, K/BxN F1 mice were treated with human recombinant AnxA1 (hrAnxA1, 1 μg/mouse) or vehicle daily. K/BxN F1 mice exhibited fully developed arthritis with normal cardiac function at 4 wk; however, by week 8, all mice displayed left ventricular diastolic dysfunction with preserved ejection fraction. This dysfunction was associated with cardiac hypertrophy, myocardial inflammation and fibrosis, and inflammatory markers. Daily treatment of K/BxN F1 mice with hrAnxA1 from weeks 4 to 8 halted progression of the diastolic dysfunction. The treatment reduced cardiac transcripts of proinflammatory cytokines and profibrotic markers. At the cellular level, hrAnxA1 decreased activated T cells and increased MHC II^low macrophage infiltration in K/BxN F1 hearts. Similar effects were obtained when hrAnxA1 was administered from week 8 to week 15. We describe an animal model of inflammatory arthritis that recapitulates the cardiomyopathy of RA. Treatment with hrAnxA1 after disease onset corrected the diastolic dysfunction through modulation of both fibroblast and inflammatory cell phenotype within the heart.

Cardiovascular Risk Associated With TNF Alpha Inhibitor Use in Patients With Rheumatoid Arthritis

Rheumatoid arthritis (RA) is an autoimmune disease characterized by inflammation and pannus formation, with subsequent joint and cartilage degradation. Treatment commonly targets inflammatory cytokines, including tumor necrosis factor (TNF) alpha, which is a potent inflammatory cytokine required for cell signaling, regulation, and apoptosis, as well as for other cellular functions including immune response. TNF alpha inhibitors have demonstrated benefits in improving RA patient outcomes in terms of immune function and symptomatology. While TNF alpha inhibitors are generally beneficial, some studies have demonstrated that TNF alpha inhibitors may increase the risk of adverse cardiovascular events. While this continues to be debated, our study investigates the role of Tumor Necrosis Factor Receptor 1 (TNFR1) and Tumor Necrosis Factor Receptor 2 (TNFR2) in cardiac tissue. TNFR1 is an apoptotic receptor and its inhibition by TNF alpha inhibitors is subsequently cardioprotective. However, TNF alpha inhibitors may be inhibiting TNFR2 receptors even more so than TNFR1 receptors. TNFR2 is primarily a cardioprotective receptor and its greater inhibition results in the cardiovascular morbidity associated with TNF alpha inhibitors.

Pathogenesis of ischaemic and non-ischaemic heart diseases in rheumatoid arthritis

Rheumatoid arthritis (RA) is characterised by a chronic inflammatory condition of the joints, but the comorbidities of RA predominantly contribute to the reduced lifespan associated with this disease. Clinical data indicate that cardiovascular disease is the major comorbidity associated with mortality in RA. In this review, we aimed to describe the pathogenesis of heart failure in RA. First, we emphasised the fundamental differences between ischaemic and non-ischaemic heart diseases and referred to their relevance in excessive cardiovascular-dependent mortality in RA. Second, we highlighted aspects of asymptomatic changes in cardiac tissue and in coronary blood vessels that are commonly found in patients with diagnosed RA. Third, we focused on high-grade systemic inflammation as a key trigger of ischaemic and non-ischaemic heart diseases in RA, and described the implication of conventional and biologic antirheumatic medications on the development and progression of heart disease. In particular, we discussed the roles of tumour necrosis factor-alpha (TNF-α) and anti-TNF-α therapies on the development and progression of ischaemic and non-ischaemic heart diseases in RA.

Cardiovascular risk in inflammatory arthritis: rheumatoid arthritis and gout

The increased risk of cardiovascular morbidity and mortality in rheumatoid arthritis and gout has been increasingly acknowledged in past decades, with accumulating evidence that gout, just as with rheumatoid arthritis, is an independent cardiovascular risk factor. Although both diseases have a completely different pathogenesis, the underlying pathophysiological mechanisms in systemic inflammation overlap to some extent. Following the recognition that systemic inflammation has an important causative role in cardiovascular disease, anti-inflammatory therapy in both conditions and urate-lowering therapies in gout are expected to lower the cardiovascular burden of patients. Unfortunately, much of the existing data showing that urate-lowering therapy has consistent beneficial effects on cardiovascular outcomes in patients with gout are of low quality and contradictory. We will discuss the latest evidence in this respect. Cardiovascular disease risk management for patients with rheumatoid arthritis and gout is essential. Clinical guidelines and implementation of cardiovascular risk management in daily clinical practice, as well as unmet needs and areas for further investigation, will be discussed.

Cardiovascular Effects of Biologic Disease-Modifying Anti-Rheumatic Drugs (DMARDs)

The risk of cardiovascular (CV) disease is increased among patients with systemic autoimmune rheumatic diseases and remains an underserved area of medical need. Although traditional risk factors for CV disease, such as hypertension, smoking, dyslipidemia and obesity contribute to endothelial dysfunction in rheumatoid arthritis (RA), they are not enough on their own to explain the observed excess CV risk. Rather, systemic inflammation seems to play a pivotal role in both disease states. Considering the inflammatory process in autoimmune diseases, scientific interest has focused on recently introduced biologic disease-modifying agents (bDMARDS) such as inhibitors of Tumor Necrosis Factor- α (ΤΝF-α), Interleukins -1 (IL-1) and -6 (IL-6). Despite the widespread use of bDMARDS in RA and other chronic autoimmune inflammatory diseases, their precise impact on CV disease and outcome remains to be elucidated, while prospective randomized control trials assessing their impact on hard CV endpoints are scarce. In this review, we summarize current knowledge concerning the effect of bDMARDs on CV outcome and on the risk of developing CV disease in patients with systemic autoimmune rheumatic diseases.

Incidence of congestive heart failure in rheumatoid arthritis: a review of literature and meta-regression analysis

AIMS

Rheumatoid arthritis (RA) is a systemic inflammatory autoimmune disorder that not only affects peripheral joints but also increases the risk for cardiovascular disease (CVD) and mortality. Heart failure (HF) appears to be one of the most important contributors to the excess mortality risk among patients with RA. We assessed the incidence of HF in patients with RA compared with age-matched and sex-matched non-RA subjects, after accounting for traditional cardiovascular risk factors and clinical ischemic heart disease.

METHODS AND RESULTS

We performed an aggregate analysis on three studies of RA patients having listed manifestations of HF. We performed a meta-regression analysis to evaluate the incidence of HF in RA patients with increased age and noted for any gender correlation. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using both fixed-effects and random-effects models. In the cumulative analysis of 5, 220, 883 patients, the incidence of HF was noted to be almost two-fold higher in patients with RA compared with a matched control population (OR 1.78, 95% CI 1.22-2.60, P < 0.003), HTN (OR 1.66, 95% CI 1.24-2.23, P < 0.001), and diabetes (OR 1.57, 95% CI 1.36-1.81, P < 0.001). Women had three-fold higher incidence of HF with RA (OR 3.38, 95% CI 2.59-4.40, P < 0.001). On meta-regression, the incidence of HF increased further with older age (coefficient = 0.12, P = 0.0004).

CONCLUSIONS

Our systematic review that included over 5 million subjects confirms the suspected increased incidence of HF in RA patients. Women have the greatest risk for HF. Our analysis advocates the need for updating the current guidelines to incorporate screening and preventive methods for HF in RA patients.

The Impact of Connective Tissue Diseases on the Inpatient Outcomes of Congestive Heart Failure Patients

Background

Rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) are autoimmune diseases with chronically elevated inflammatory activity. Treatments typically have been aimed at decreasing inflammation. While RA and SLE are known to have a high incidence of congestive heart failure (HF), the mechanism behind this remains elusive. We sought to assess the outcomes of HF patients with either RA or SLE as opposed to HF patients without RA or SLE.

Methods

We conducted a retrospective analysis of the Healthcare Utilization Project - National Inpatient Sample Database from 2010 to 2015 (third quarter). Patients with a primary admitting diagnosis of HF were queried, and those with or without a diagnosis of either SLE or RA were separated into two groups. In-hospital mortality, total charges (TOTCHG), and length of stay (LOS) were analyzed with a multivariate regression model adjusted for demographical and comorbidity variables, using generalized linear models with family binomial, gamma, and negative-binomial, respectively. A p-value smaller than 0.05 was deemed statistically significant. All the statistical analyses were performed in R 3.5.5 (R Core Team, 2013, http://www.R-project.org/).

Results 

The in-hospital mortality (3.4% v/s 4.43%), mean TOTCHG ($46k v/s $51k), and mean LOS (5.79 v/s 6.12 days) were significantly lower in HF patients with RA/SLE when compared with HF patients without RA/SLE. A younger age (70.5 v/s 72.6 years) and a female preponderance (75% v/s 51%) were evident in the RA/SLE group. Both groups consistently showed a significant disparity in the rates of hospitalization, which was inversely related to household income. p-value was less than 0.001 for all the above outcomes.

Conclusions 

RA/SLE patients are associated with better in-hospital outcomes of HF. The underlying mechanism is unclear in terms of this paradox. Given the fact that the majority of RA/SLE patients are treated with agents aimed at decreasing inflammation, this may shed light on the role of inflammation being an important contributor to HF and implicate a future therapeutic direction.

Chronic Heart Failure in Early Rheumatoid Arthritis Patients Prior to Basic Antirheumatic Therapy

Aim. To study the clinical manifestations and factors associated with the presence of chronic heart failure (CHF) in patients with early rheumatoid arthritis (RA) prior to anti-inflammatory therapy. Material and methods. The study included 74 patients with valid diagnosis of RA (criteria ACR/EULAR, 2010), 56 women (74%), median age – 54 [46;61] years, disease duration – 7 [4;8] months; seropositive for IgM rheumatoid factor (87%) and/or antibodies to cyclic citrullinated peptide (100%) prior to taking disease modifying anti-rheumatic drugs and glucocorticoids. CHF was verified in accordance with actual guidelines. The assessment of traditional risk factors for cardiovascular diseases, echocardiography, tissue Doppler imaging, carotid artery ultrasound, were carried out before the start of therapy in all patients with early RA. The concentration of NT-proBNP was determined by electrochemiluminescence. The normal range for NT-proBNP was less than 125 pg/ml.

Results. CHF was diagnosed in 24 (33%) patients: in 23 patients – CHF with preserved ejection fraction, in 1 patient – CHF with reduced ejection fraction. 50% of patients with RA under the age of 60 were diagnosed with CHF. NYHA class I was found in 5 (21%) patients, class II – in 15 (63%), class III – in 1 (4%). Positive predictive value of clinical symptoms did not exceed 38%. All patients with early RA were divided into two groups: 1 – with CHF, 2 – without CHF. Patients with RA+CHF compared with patients without CHF were older, had higher body mass index, frequency of carotid atherosclerosis, of ischemic heart disease (IHD), hypertension, C-reactive protein (CRP) levels and intima media thickness. Independent factors associated with the presence of CHF were identified by linear regression analysis: abdominal obesity, CRP level, systolic blood pressure, dyslipidemia, carotid intima thickness, IHD. The multiple coefficient of determination was R2=57.1 (R-0.76, p<0.001). Level of NT-proBNP in RA patients with CHF (192.0 [154.9; 255.7] pg/ml) was higher than in RA patients without CHF (77 [41.1; 191.2] pg/ml) and in control (49.0 [33.2; 65.8] pg/ml), p<0.0001 and p=0.01, respectively. To exclude CHF in patients with early RA, the optimal NT-proBNP level was 150.4 pg/ml (sensitivity – 80%, specificity – 79%), the area under the ROC curve = 0.957 (95% confidence interval 0.913-1.002, p<0.001).

Conclusion. CHF was detected in a third of RA patients at the early stage of the disease. Factors associated with the presence of CHF were abdominal obesity, CRP level, systolic blood pressure, dyslipidemia, intima media thickness, IHD.

Chronic Heart Failure in Rheumatoid Arthritis Patients (Part III): Effects of Antirheumatic Drugs

Chronic autoimmune inflammation is one of the leading risk factors for the development of chronic heart failure (CHF) in rheumatoid arthritis (RA). The purpose of the review is to analyze the results of investigations on the effects of conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs), biological disease-modifying anti-rheumatic drugs (bDMARDs), and targeted csDMARDs on cardiac function and the risk of developing CHF in patients with RA. Methotrexate may reduce the CHF risk and have a positive effect on the course of this condition in patients with RA. Despite the data on the presence of leflunomide effects that impede myocardial remodeling, there is no evidence of the role of the drug in the prevention of CHF in RA patients. Hydroxychloroquine may contribute to the prevention of CHF, but the risk of developing severe cardiotoxicity should be considered when taking the drug for a long time. Most studies have not revealed the negative effect of tumor necrosis factor inhibitors on the prevalence and incidence of new cases of CHF in RA patients, and an improvement in the structure and function of the heart during therapy has been shown. Inhibitors of interleukin (IL) -1, inhibitors of IL-6, inhibitors of T-cell co-stimulation, anti-B-cell therapy, targeted csDMARDs do not increase the risk of CHF and may have cardioprotective effects, including slowing the progression of left ventricle myocardial dysfunction. Due to the high risk of CHF and CHF-associated mortality in RA patients, early diagnosis of cardiac dysfunction, development of a prevention and treatment strategies are needed, including high-quality prospective studies to assess the effect of anti-rheumatic therapy on myocardial function, risk of developing and decompensation of CHF in RA patients. It is possible that some drugs may possess protective effects on cardiomyocytes so they could become the first-line drugs in patients with CHF or the risk of its development.

[Level of N-terminal fragment of brain natriuretic peptide progenitor and atherosclerotic damage of brachocephalic arteries in patients with rheumatoid arthritis with inefficiency and/or injurability of basic anti - inflammatory treatment]

The high prognostic significance of the concentration of the N-terminal - pro-B-type natriuretic peptide (NT-proBNP) in the development of cardiovascular diseases (CVD) was identified for rheumatoid arthritis (RA) and general populations.

AIM

to investigate the significance of NT-proBNP level in patients (pts) with RA with the ineffectiveness and/or intolerance of basic anti - inflammatory therapy; compare the level of NT-proBNP with atherosclerotic lesion of the brachiocephalic arteries (BCA), traditional risk factors and inflammatory markers.

MATERIALS AND METHODS

The investigation enrolled 28 pts (24women/4men) with the lack of efficacy/resistance and/or intolerance of basic anti - inflammatory drugs (DMARDs); median age was 55 [46; 61] years, median disease duration 114 [60; 168] month; DAS28 6,2 [5.1; 7.0]; SDAI 35.0[23.9; 51.0], CDAI 30.0[21.0; 42.0], serum positivity for rheumatoid factor (RF) (100%)/anti - cyclic citrullinated peptide antibodies (ACCP) (86%). The study did not include RA pts with congestive heart failure. High incidence of traditional risk factors was found in RA pts: arterial hypertension - in 75%, dyslipidemia - 61%, smoking - 17%, overweight - 61%, family history of cardiovascular diseases - 36%, hypodynamia - 68%. Coronary artery disease was diagnosed in 11% RA pts. Lack of efficacy of 3 or more DMARDs was found in 46% of pts, intolerance to previous therapy with DMARDs - in 54% pts. 47% were receiving methotrexate (20 [18; 25] mg/week), 11% - leflunomide, 7% - sulfasalazine, 46% - glucocorticoids, 75% - non - steroidal anti - inflammatory drugs. The control group consisted of 20 healthy donors, comparable to pts by age and sex. Serum levels of of NT-proBNP were measured using electrochemiluminescence method Elecsys proBNP II (Roche Diagnostics, Switzerland). The determination of the intima - media thickness (IMT) BCA were assessed from duplex scanning. Atherosclerotic lesion of BCA was assessed by the presence of atherosclerotic plaque (IMT ≥1.2 mm).

RESULTS

NT-proBNP concentrations in RA pts proved to be higher (78.7 [41.4; 101.3] pg/ml) than those in the control group (55.3 [36.6; 67.3] pg/ml, p100 pg/ml - 1 group (n=6) and ≤100 pg/ml - 2 group (n=22). Groups of RA pts did not differ in gender, age, activity of RA, frequency of detection of traditional risk factors. Atherosclerotic lesion of the BCA was detected in 3 (50%) pts of the 1 group and in 8 (36%) pts of the 2 group (p>0.05). In RA pts the level of NT-proBNP correlated with age (r=0.39; p.

Chronic Heart Failure in Rheumatoid Arthritis Patients (Part II): Difficulties of Diagnosis

Rheumatoid arthritis (RA) is characterized by a twofold increase in morbidity and mortality due to chronic heart failure (CHF). At the same time, the prevalence of CHF among RA patients is significantly underestimated. The aim of the review was to analyze the results of the main studies on the features of the clinical presentation of heart failure (HF) in RA patients, the role of visualization techniques and biomarkers in the diagnosis of HF and preclinical dysfunction of the myocardium. HF in patients with RA is characterized by a predominance of HF with a preserved left ventricular ejection fraction (LVEF). The use of clinical diagnostic criteria in RA patients can lead to both over- or underdiagnosis of CHF. Systolic dysfunction estimated by LVEF is rare in RA and does not reflect the real frequency of myocardial dysfunction. Echocardiography (ECHO-CG) with tissue Doppler echocardiography (TDE) and visualization of myocardial deformation, magnetic resonance imaging (MRI) of the heart in RA patients revealed a high frequency of HF with preserved ejection fraction, left ventricular remodeling and hypertrophy, pre-clinical systolic and diastolic dysfunction. Determination of natriuretic peptides is useful for verifying the diagnosis of HF and estimating the prognosis in this cohort, despite the possible decrease in the sensitivity and specificity of these indicators in RA patients. The review discusses the advantages of MRI of the heart, including quantitative T1 and T2 regimens, in the diagnosis of myocarditis, myocardial fibrosis, and myocardial perfusion disorders in RA patients. In order to verify the diagnosis of heart failure and detect pre-clinical myocardial dysfunction in RA patients, the determination of natriuretic peptides concentration should become part of the routine examination, beginning with the debut of the disease, along with the collection of a cardiological history, physical examination, ECHO-CT with TDE, and visualization of myocardial deformation. Evaluation of the quantitative characteristics of tissue according to MRI of the heart could improve the diagnosis of myocardial damage.

Diastolic dysfunction in rheumatoid arthritis patients with low disease activity

INTRODUCTION/OBJECTIVES

Patients with rheumatoid arthritis (RA) are at increased risk for congestive heart failure (CHF) and left ventricular diastolic dysfunction (LVDD), as compared to the general population. High disease activity is to be associated with higher incidence of cardiovascular disease (CVD), CHF, and mortality in RA patients. LVDD is not anticipated in RA patients without CVD symptoms and may be underdiagnosed especially in those with low disease activity.

METHOD

The study group consisted of 70 RA patients (54 women, 16 men) with no CVD and 33 healthy controls, of comparable age. All RA patients had low disease activity (DAS28 ≤ 3.2) from 2 to 7 years. Laboratory and imaging assessments included metabolic, RA-related, and cardiovascular parameters. Echocardiographic and Doppler studies were conducted in patients and controls with assessment of ejection fraction (EF) and diastolic dysfunction (assessed as E/A ratio).

RESULTS

The mean E/A ratio did not differ significantly between RA patients and healthy controls (1.08 (0.28) vs 0.99 (0.21), NS); comparable numbers of patients and controls had abnormal E/A (< 1.0) (26 (37.1%) vs 10 (30.3%), NS). Patients with decreased E/A were significantly older and had higher disease duration, activity, and presence of bone erosions than their RA counterparts with normal E/A. The mean EF was not significantly different in patients and controls.

CONCLUSIONS

The prevalence of DD as expressed by E/A ratio in RA patients with continued low disease activity was not different from that of controls. Higher disease duration and severity may predispose to DD occurrence in patients with preserved EF.

Enhanced ventricular-arterial coupling during a 2-year physical activity programme in patients with rheumatoid arthritis: a prospective substudy of the physical activity in rheumatoid arthritis 2010 trial

OBJECTIVE

To establish how guided physical activity in patients with rheumatoid arthritis (RA) without known cardiovascular disease affected vascular and cardiac function, and how these two entities were prospectively interconnected in this patient group.

METHODS

Prospective substudy of 29 participants in the Physical Activity in RA (PARA) 2010 trial. All subjects were examined at baseline, at year 1 and 2 with measures of pulse wave velocity and arterial augmentation index, as well as echocardiographic evaluation of diastolic parameters and ventricular-arterial coupling. Muscle strength and aerobic exercise capacity were assessed at baseline and yearly. All participants performed physiotherapist-guided aerobic and muscle strength exercise during 2 years and were reminded through SMS to report physical activity progress.

RESULTS

This cohort of patients with RA exhibited increased vascular stiffness despite normal blood pressure. At baseline, lower muscle strength was associated with increased vascular stiffness (β = 0.68; P = 0.004), whereas lower aerobic working capacity was associated with left ventricular diastolic dysfunction (β = 0.85; P = 0.03). There was a significant positive correlation between vascular stiffness and diastolic dysfunction at baseline (R²  = 0.64) and for the changes in those parameters observed during 2 years of guided physical activity. Finally, a significant improvement in ventricular-arterial coupling was observed after exercise (P < 0.001).

CONCLUSION

These results indicate that although differentially associated with physical capacity parameters, improved vascular stiffness and improved diastolic dysfunction are interrelated, and that an optimization of the ventricular-arterial coupling may contribute to the beneficial effects of physical activity in patients with RA.

Cardiovascular system changes in rheumatoid arthritis patients with continued low disease activity

Systemic inflammation and disease activity seem to contribute to excessive prevalence of cardiovascular (CV) diseases (CVDs) in patients with rheumatoid arthritis (RA). The objective of the study was to assess chosen CV parameters in RA patients who have continuous low disease activity. The study group consisted of 70 RA patients without known CVD and 33 healthy controls, of a comparable age. All RA patients had continued low disease activity (DAS28 ≤ 3.2) from 2 to 7 years. The groups were assessed for: blood pressure, serum amino-terminal pro-brain natriuretic peptide (NT-proBNP), carotid intima media thickness (cIMT), electrocardiography (ECG), ejection fraction (EJ) and diastolic dysfunction (E/A ratio) in echocardiography. In RA patients in comparison with controls, significantly greater values of cIMT [0.83 (0.21) vs 0.62 (0.1) mm, p < 0.001] were found, as well as higher incidence of atherosclerotic plaques [43 (61.4%) vs 10 (30.3%), p = 0.003], prolonged QTc interval [439.6 (23.7) vs 414.0 (27.9) ms, p < 0.001]. High or very high Systemic Coronary Risk Evaluation (SCORE) was found in 32.9% of patients with RA and increased serum NT-proBNP in 71.4%. The mean values of CV parameters (cIMT, E/A, NT-proBNP, SCORE) were associated with age, disease duration, rheumatoid factor (RF-IgM), erythrocyte sedimentation rate (ESR). The results of our study indicate, that RA with continued low disease activity is associated with atherosclerosis and heart dysfunction. Strong relationships were found between CV parameters and patients' age, disease duration. Deterioration of CV parameters was associated with higher DAS28, ESR, RF-IgM concentration and bone erosions.

One-Year Follow-up Study Detects Myocardial Changes with Cardiovascular Magnetic Resonance Tagging in Active Rheumatoid Arthritis

RATIONALE AND OBJECTIVES

To evaluate the effects of 1 year of medical treatment on myocardial function in active rheumatoid arthritis (RA).

MATERIALS AND METHODS

Thirty-nine female patients with RA without any known cardiovascular disease underwent a cardiovascular magnetic resonance (CMR) examination before and after 1 year of antirheumatic treatment. The population comprised untreated active early RA (ERA) and chronic RA patients, who were grouped accordingly. The CMR protocol included volumetric determinations, late gadolinium enhancement imaging, myocardial tagging, and native T1 mapping. DAS28-CRP disease activity scores were calculated before and after the treatment.

RESULTS

Results are reported as median (quartile 1-quartile 3). Time to peak diastolic filling rate improved in ERA (495 [443-561] ms vs 441 [340-518] ms, P = .018). Peak diastolic mean mid short-axis circumferential strain rate of all six segments was improved (82 [74-91] %/s vs 91 [77-100] %/s, P = .05), particularly in the anterior segment (82 [63-98] %/s vs 86 [77-109] %/s, P = .013). DAS28-CRP decreased in ERA (3.8 [3.2-4.1] vs 1.6 [1.4-2.2], P < .001). In chronic RA, no statistically significant improvement was detected.

CONCLUSIONS

Early treatment of active RA is important, as myocardial function detected with CMR tagging improved in ERA in parallel with decreasing inflammatory activity.

Safety and Efficacy of Biological Disease-Modifying Antirheumatic Drugs in Older Rheumatoid Arthritis Patients: Staying the Distance

The population of older individuals with rheumatoid arthritis (RA) is rapidly expanding, mainly due to increased life expectancy. While targeted biological therapies are well established for the treatment of this disease, their use may be lower in older patients (age > 65 years) and very old patients (age > 75 years) as a result of perceived higher risks for adverse events in this population, taking into account comorbidity, polypharmacy, and frailty. In this review, we discuss the available evidence for the use of biological therapies in this growing patient group with specific attention towards the eventual reasons for biological treatment failure or withdrawal. The majority of data is found in secondary analyses of clinical trials and in retrospective cohorts. The most information available is on tumor necrosis factor (TNF) blockers. Older patients seem to have a less robust response to anti-TNF agents than a younger population, but drug survival as a proxy for efficacy does not seem to be influenced by age. Despite an overall rate of adverse effects comparable to that in younger patients, older RA patients are at higher risk of serious infections. Other biologics appear to have an efficacy similar to anti-TNF agents, also in older RA patients. Again, the drug survival rates for tocilizumab, rituximab, and abatacept resemble those in young RA patients with good general tolerability and safety profiles. The cardiovascular risk and the risk of cancer, increased in RA patients and in the older RA patients, do not appear to be strongly influenced by biologicals.

What is the impact of biologic therapies on common co-morbidities in patients with rheumatoid arthritis?

Biologic therapies have revolutionised disease control in patients with rheumatoid arthritis (RA). Theoretically, they have the potential to influence co-morbid disease associated with RA through better control of systemic inflammation. Conversely, co-morbidity may occur as an adverse effect of the drugs. The latest evidence from observational data shows an increased risk of infection in the first 6 months of treatment with tumour necrosis factor inhibitor (TNFi) therapies and potentially other biologic therapies. Rates of infection after the first 6 months decrease and become comparable to patients with RA treated with conventional synthetic disease modifying anti-rheumatic drugs (csDMARDs). TNFi also appear to reduce the risk of cardiovascular disease in these patients, in particular ischaemic heart disease. TNFi treatment may be associated with a small increase in the risk of developing squamous cell carcinoma of the skin; in terms of other cancers, rates appears to be no different to those seen in patients treated with csDMARDs. There is a paucity of data on the impact of other biologic therapies and the effect of all biologic therapies on other common co-morbidities.

Parameters indicative of persistence of valvular pathology at initial diagnosis in acute rheumatic carditis: the role of albumin and CD19 expression

OBJECTIVE

The aim of this study is to define the predictors of chronic carditis in patients with acute rheumatic carditis (ARC).

METHODS

Patients diagnosed with ARC between May 2010 and May 2011 were included in the study. Echocardiography, electrocardiography, lymphocyte subset analysis, acute phase reactants, plasma albumin levels, and antistreptolysin-O (ASO) tests were performed at initial presentation. The echocardiographic assessments were repeated at the sixth month of follow-up. The patients were divided into two groups according to persistence of valvular pathology at 6th month as Group 1 and Group 2, and all clinical and laboratory parameters at admission were compared between two groups of valvular involvement.

RESULTS

During the one-year study period, 22 patients had valvular disease. Seventeen (77.2%) patients showed regression in valvular pathology. An initial mild regurgitation disappeared in eight patients (36.3%). Among seven (31.8%) patients with moderate regurgitation initially, the regurgitation disappeared in three, and four patients improved to mild regurgitation. Two patients with a severe regurgitation initially improved to moderate regurgitation (9.1%). In five (22.8%) patients, the grade of regurgitation [moderate regurgitation in one (4.6%), and severe regurgitation in 4 (18.2%)] remained unchanged. The albumin level was significantly lower at diagnosis in Group 2 (2.6±0.48g/dL). Lymphocyte subset analysis showed a significant decrease in the CD8 percentage and a significant increase in CD19 percentage at diagnosis in Group 2 compared to Group 1.

CONCLUSION

The blood albumin level and the percentage of CD8 and CD19 (+) lymphocytes at diagnosis may help to predict chronic valvular disease risk in patients with acute rheumatic carditis.
