Background/Aims: The high incidence of cardiovascular disease (CVD) in patients with autoimmune rheumatic diseases (ARDs) is the main driver towards increased mortality in this patient group. Cardiovascular magnetic resonance (CMR) can non-invasively and robustly detect CVD in ARD patients at an early stage of development. The review summarises the diagnostic information provided by CMR in ARD patients. Summary: CMR uses a strong magnetic field combined with radio-frequency pulses (pulse sequences) to generate images. Firstly, balanced steady-state free precession (bSSFP) can be used for evaluating cardiac anatomy, mass, wall motion, atrial/ventricular function. Secondly, T2-weighted imaging (T2-W) can be used for oedema detection, which appears as a high signal intensity area on STIR (short tau inversion recovery) images. T2 mapping is a newer T2-W technique that can provide more optimal identification of myocardial oedema. Lastly, late gadolinium enhanced (LGE) T1-W images, taken 15 min. after injection of contrast agent, allow the detection of myocardial replacement fibrosis, which appears as a bright area in a background of black myocardium. However, LGE has inherent disadvantages for the assessment of diffuse myocardial fibrosis. Therefore, T1 mapping and extracellular volume fraction (ECV) have been developed to quantify diffuse myocardial fibrosis. Results: Although multicentre studies are still missing, the CMR parameters have been extensively applied for the identification of oedema/fibrosis and treatment decision making in ARDs. Conclusions: Tissue characterisation with CMR allows early and robust identification of CVD in ARD patients and contributes to personalized management in the patients. © 2021. All Rights Reserved.

Introduction: Patients with autoimmune rheumatic diseases (ARDs) are at increased risk for pneumococcal infections and should be vaccinated against Streptococcus pneumoniae. Data on the rates of pneumococcal vaccination among patients with ARDs in Southern Europe are scarce. Here, we estimate the pneumococcal vaccination rate in patients living in Greece with ARDs, explore the patients’ awareness regarding vaccination, and try to recognize factors that influence the vaccine uptake. Methods: Between October 2015 and September 2016, a structured questionnaire was provided to all consecutive patients with ARDs attending one outpatient clinic of our department. The survey included parameters concerning patients’ demographics, underlying ARD and immunosuppressive medications, other comorbidities, vaccine type, knowledge about infection risk and necessity of vaccination. Univariate and multivariate analyses were performed to study any association of these factors with the vaccination uptake. Results: Overall, 395 patients with ARDs (30.13% aged >65 years and 78.99% female) participated in our survey. The most frequent ARD was rheumatoid arthritis (43.04%); 40.51% of patients were receiving biologic agents and 44.56% steroids. Pneumococcal vaccination rate was 49.37%, while 45.06% of patients have been vaccinated during the last five years and only 8.21% of them had a second pneumococcal vaccine, as per national guidelines. The decision of vaccination was significantly influenced by the patient's age (>65 years) (p < 0.001) and the complete awareness of reasons for being vaccinated (p < 0.001), but not by presence of comorbidities, the type of ARD or administration of a biologic agent. The main reason for no vaccination was that it was not suggested by the caring physician (82.50%). Conclusions: In our cohort of patients with ARDs the pneumococcal vaccination was suboptimal. Better understanding of the significance of vaccination by the patient and suggestion for vaccination by the caring physician will improve vaccination uptake and optimize the clinical benefits among patients with ARDs. © 2021 Elsevier Ltd

Purpose of Review: To present the interaction between brain/heart and emphasize the role of combined brain/heart magnetic resonance imaging (MRI) in patients with rheumatoid arthritis (RA) and other seronegative spondyloarthropathies (SNA). Recent Findings: Both traditional cardiovascular disease (CVD) risk factors and intrinsic RA/SNA features contribute to the increased CVD-related morbidity/mortality. CVD in RA usually occurs a decade earlier than age- and sex-matched controls, and RA patients are twice more likely to develop myocardial infarction irrespective of age, history of prior CVD, and traditional CVD risk factors. RA also increases risk of non-ischemic heart failure (HF), valvular disease, and myo-pericarditis. CVD in SNA affects more commonly patients with long-standing disease. Ascending aortitis, aortic/mitral insufficiency, conduction defects, and diastolic dysfunction are the commonest findings in ankylosing spondylitis (AS). CVD is also the leading cause of death in psoriatic arthritis (PsA), due to myopericarditis, diastolic dysfunction, and valvular disease. Brain damage, due to either ischemic or hemorrhagic stroke and silent vascular damage, such as white matter hyperenhancement (WMH), is increased in both RA/SNA and may lead to cognitive dysfunction, depression, and brain atrophy. Magnetic resonance imaging (MRI) is ideal for serial brain/heart evaluation of patients with systemic diseases. Summary: RA/SNA patients are at high risk for brain/heart damage at early age, irrespectively of classic risk factors. Until more data will be obtained, a combined brain/heart MRI evaluation can be proposed in RA/SNA with new onset of arrhythmia and/or HF, cognitive dysfunction and/or depression. © 2020, Springer Science+Business Media, LLC, part of Springer Nature.

Background: Autoimmune rheumatic diseases (ARDs) may affect both the heart and the brain. However, little is known about the interaction between these organs in ARD patients. We asked whether brain lesions are more frequent in ARD patients with cardiac symptoms compared with non-ARD patients with cardiovascular disease (CVD). Methods: 57 ARD patients with mean age of 48 ± 13 years presenting with shortness of breath, chest pain, and/or palpitations, and 30 age-matched disease-controls with non-autoimmune CVD, were evaluated using combined brain– heart magnetic resonance imaging (MRI) in a 1.5T system. Results: 52 (91%) ARD patients and 16 (53%) controls had white matter hyperintensities (p < 0.001) in at least one brain area (subcortical/deep/periventricular white matter, basal ganglia, pons, brainstem, or mesial temporal lobe). Only the frequency and number of subcortical and deep white matter lesions were significantly greater in ARD patients (p < 0.001 and 0.014, respectively). ARD vs. control status was the only independent predictor of having any brain lesion. Specifically for deep white matter lesions, each increase in ECV independently predicted a higher number of lesions [odds ratio (95% confidence interval): 1.16 (1.01–1.33), p = 0.031] in ordered logistic regression. Penalized logistic regression selected only ARD vs. control status as the most important feature for predicting whether brain lesions were present on brain MRI (odds ratio: 5.46, marginal false discovery rate = 0.011). Conclusions: Subclinical brain involvement was highly prevalent in this cohort of ARD patients and was mostly independent of the severity of cardiac involvement. However, further research is required to determine the clinical relevance of these findings. © 2020 by the authors. Licensee MDPI, Basel, Switzerland.

Purpose of Review: Autoimmune rheumatic diseases (ARDs) affect 8% of the population and approximately 78% of patients are women. Myocardial disease in ARDs is the endpoint of various pathophysiologic mechanisms including atherosclerosis, valvular disease, systemic, myocardial, and/or vascular inflammation, as well as myocardial ischemia and replacement/diffuse fibrosis. Recent Findings: The increased risk of CVD in ARDs leads to excess comorbidity not fully explained by traditional cardiovascular risk factors. It seems that the chronic inflammatory status typically seen in ARDs, promotes both the development of myocardial inflammation/fibrosis and the acceleration of atherosclerosis. Summary: CMR (cardio-vascular magnetic resonance) is the ideal imaging modality for the evaluation of cardiac involvement in patients with ARDs, as it can simultaneously assess cardiac function and characterize myocardial tissues with regard to oedema and fibrosis. Due to its high spatial resolution, CMR is capable of identifying various disease entities such as myocardial oedema /inflammation, subendocardial vasculitis and myocardial fibrosis, that are often missed by other imaging modalities, notably at an early stage of development. Although generally accepted guidelines about the application of CMR in ARDs have not yet been formulated, according to our experience and the available published literature, we recommend CMR in ARD patientS with new-onset heart failure (HF), arrhythmia, for treatment evaluation/change or if there is any mismatch between patient symptoms and routine non-invasive evaluation. © 2020, Springer Science+Business Media, LLC, part of Springer Nature.

Psoriatic arthritis (PsA) patients are at a higher risk of systemic inflammatory sequelae, leading to microalbuminuria, cardiovascular (CVD) and neuropsychiatric (NPD) disease. Our aim is to present the existing literature about the relationship between CVD, kidney and NPD in PsA. The literature evaluation of PsA revealed that chronic T-cell activation and increased levels of circulating immune complexes can cause glomerular injury leading to microalbuminuria, which predicts CVD and all-cause mortality in both diabetic and non-diabetic patients. Furthermore, it is a marker of preclinical brain damage and identifies patients at higher risk of NPD/CVD events. Among the currently used imaging modalities in PsA, magnetic resonance imaging (MRI) maintains a crucial role, because it is ideal for concurrent evaluation of brain/heart involvement and serial follow up assessment. There is increasing evidence regarding the relationship between kidneys, heart and brain in PsA. Although currently there are no official recommendations about a combined brain/heart MRI in PsA, it could be considered in PsA with microalbuminuria, arrhythmia, HF, cognitive dysfunction and/or depression. © 2020, Springer-Verlag GmbH Germany, part of Springer Nature.

Aims: T1-mapping is considered a surrogate marker of acute myocardial inflammation. However, in diffuse cutaneous systemic sclerosis (dcSSc) this might be confounded by coexisting myocardial fibrosis. We hypothesized that T1-based indices should not by themselves be considered as indicators of myocardial inflammation in dcSSc patients. Methods/Results: A cohort of 59 dcSSc and 34 infectious myocarditis patients was prospectively evaluated using a 1.5-Tesla system for an indication of suspected myocardial inflammation and was compared with 31 healthy controls. Collectively, 33 (97%) and 57 (98%) of myocarditis and dcSSc patients respectively had ≥1 pathologic T2-based index. However, 33 (97%) and 45 (76%) of myocarditis and dcSSc patients respectively had ≥1 pathologic T2-based index. T2-signal ratio was significantly higher in myocarditis patients compared with dcSSc patients (2.5 (0.6) vs. 2.1 (0.4), p < 0.001). Early gadolinium enhancement, late gadolinium enhancement and T2-mapping did not differ significantly between groups. However, both native T1-mapping and extracellular volume fraction were significantly lower in myocarditis compared with dcSSc patients (1051.0 (1027.0, 1099.0) vs. 1120.0 (1065.0, 1170.0), p < 0.001 and 28.0 (26.0, 30.0) vs. 31.5 (30.0, 33.0), p < 0.001, respectively). The original Lake Louise criteria (LLc) were positive in 34 (100%) myocarditis and 40 (69%) dcSSc patients, while the updated LLc were positive in 32 (94%) and 44 (76%) patients, respectively. Both criteria had good agreement with greater but nonsignificant discordance in dcSSc patients. Conclusions: ∼25% of dcSSc patients with suspected myocardial inflammation had no CMR evidence of acute inflammatory processes. T1-based indices should not be used by themselves as surrogates of acute myocardial inflammation in dcSSc patients. © 2020 by the authors. Licensee MDPI, Basel, Switzerland.

Background: Acute cardiac events are a significant contributor to mortality in systemic sclerosis (SSc). However, echocardiographic evaluation may be deceptively normal during an acute presentation. We hypothesized that in diffiuse SSc patients presenting with acute cardiac events and a normal echocardiogram, cardiovascular magnetic resonance (CMR) would have incremental diagnostic/prognostic value. Methods. 50 consecutive diffiuse SSc patients with normal echocardiograms were evaluated using a 1.5T system. A total of 27 (63%) had experienced an acute cardiac event three to tendays beforeCMRevaluation (rhythm disturbances, angina pectoris, shortness of breath). Left/right ventricular (LV/RV) volumes and ejection fractions (EF), as well as LV mass, the T2-signal ratio, early/late gadolinium enhancement (EGE/LGE), native/post-contrast T1-mapping, T2-mapping and extracellular volume fraction (ECV) were compared between the event and no-event groups. Results: No differences were identified in LV/RV volumes/EF/mass. In logistic regression analyses, independent predictors of belonging to the event group were EGE (odds ratio (95% CI): 1.55 (1.06-2.26), p = 0.024), LGE (1.81 (1.23-2.67), p = 0.003), T2 mapping (1.20 (1.06-1.36), p = 0.004) and native/post-contrast T1 mapping (1.17 (1.04-1.32), p = 0.007 and 0.86 (0.75-0.98), p = 0.025). At a median follow-up of ∼1.2 years, 42% vs. 11% of the event/no-event group respectively reached a combined endpoint of event occurrence/recurrence or cardiovascular mortality. Of the independent predictors resulting from logistic regression analyses, only LGE (hazard ratio (95% CI): 1.20 (1.11-1.30), p < 0.001), T2-mapping (1.07 (1.01-1.14), p = 0.025) and native T1-mapping (1.08 (1.01-1.15), p = 0.017) independently predicted the combined endpoint. Conclusions: A normal echocardiogram does not preclude myocardial lesions in diffiuse SSc patients, which can be detected by CMR especially in symptomatic patients. © 2019 by the authors.

Background: Ventricular tachycardia/fibrillation (VT/VF) may occur in autoimmune rheumatic diseases (ARDs). We hypothesized that cardiovascular magnetic resonance (CMR) can identify arrhythmogenic substrates in ARD patients. Patients - methods: Using a 1.5 T system, we evaluated 61 consecutive patients with various types of ARDs and normal left ventricular ejection fraction (LVEF) on echocardiography. A comparison of patients with recent VT/VF and those that never experienced VT/VF was performed. CMR parameters included left and right ventricular (LV and RV) end-systolic and end-diastolic volumes (ESV and EDV), T2 signal ratio of myocardium over skeletal muscle, early/late gadolinium enhancement (EGE and LGE), T1/T2-mapping and extracellular volume fraction (ECV). Results: 21 (34%) patients had a history of recent, electrocardiographically identified, VT/VF. No demographic or functional CMR variables differed significantly between groups. The same was the case for T2 signal ratio and EGE/LGE. Median native T1 mapping values were significantly higher in patients with VT/VF compared to those without [1135.0 (1076.0, 1201.0) vs. 1050.0 (1025.0, 1078.0), p < 0.001], as was the case for mean T2 mapping [60.4 (6.6) vs. 55.0 (7.9), p = 0.009] and median ECV values [32.0 (30.0, 32.0) vs. 29.0 (28.0, 31.5), p = 0.001]. After multivariate corrections for age, LVEDV, LVEF, RVEDV, RVEF, T2 signal ratio, EGE and LGE, these remained significant predictors of having experienced VT/VF in the past. Conclusions: T1/T2-mapping and ECV offer incremental value as identifiers of arrhythmogenic substrates in ARD patients, beyond traditionally used indices. They can thus guide implantable cardiac defibrillator (ICD) implantation in ARD patients presenting with VT/VF and normal LVEF. © 2018 Elsevier B.V.

Background: Accurate diagnosis of cardiovascular involvement in systemic lupus erythematosus (SLE) remains challenging, due to limitations of echocardiography. We hypothesized that cardiovascular magnetic resonance can detect cardiac lesions missed by echocardiography in SLE patients with atypical symptoms. Aim: To use cardiovascular magnetic resonance in SLE patients with atypical symptoms and investigate the possibility of silent heart disease, missed by echocardiography. Patients/methods: From 2005 to 2015, 80 SLE patients with atypical cardiac symptoms/signs (fatigue, mild shortness of breath, early repolarization and sinus tachycardia) aged 37 ± 6 years (72 women/8 men), with normal echocardiography, were evaluated using a 1.5 T system. Left and right ventricular ejection fractions, T2 ratio (oedema imaging) and late gadolinium enhancement (fibrosis imaging) were assessed. Acute and chronic lesions were defined as late gadolinium enhancement-positive plus T2>2 and T2

Sudden cardiac death (SCD) is due to ventricular tachycardia/fibrillation (VT/VF) and may occur with or without any structural or functional heart disease. The presence of myocardial edema, ischemia and/or fibrosis plays a crucial role in the pathogenesis of VT/VF, irrespective of the pathophysiologic background of the disease. Specifically, in autoimmune rheumatic diseases (ARDs), various entities such as myocardial/vascular inflammation, ischemia and fibrosis may lead to VT/VF. Furthermore, autonomic dysfunction, commonly found in ARDs, may also contribute to SCD in these patients. The only non-invasive, radiation-free imaging modality that can perform functional assessment and tissue characterization is cardiovascular magnetic resonance (CMR). Due to its capability to detect and quantify edema, ischemia and fibrosis in parallel with ventricular function assessment, CMR has the great potential to identify ARD patients at high risk for VT/VF, thus influencing both cardiac and anti-rheumatic treatment and modifying perhaps the criteria for implantation of cardioverter defibrillators. © 2018, Springer-Verlag GmbH Germany, part of Springer Nature.

Background Peripheral Raynaud's phenomenon (RP) is either primary (PRP), without any coexisting disease or secondary (SRP), due to connective tissue diseases (CTD). We hypothesized that adenosine stress cardiovascular magnetic resonance (CMR) can assess myocardial perfusion in a population of PRP and SRP. Patients-methods Twenty CTDs, aged 30.6 ± 7.5 yrs., 16F/4M, including 9 systemic sclerosis (SSc), 4 systemic lupus erythematosus (SLE), 3 mixed connective tissue disease (MCTD), 2 polymyositis (PM) and 2 rheumatoid arthritis (RA), with SRP, under treatment with calcium blockers, were evaluated by stress CMR and compared with age-sex matched PRP and controls. All RP patients were under treatment with calcium blockers. Stress perfusion CMR was performed by 1.5 T system using 140 mg/kg/min adenosine for 4 min and 0.05 mmol/kg Gd-DTPA for first-pass perfusion. A rest perfusion was performed with the same protocol. Late gadolinium enhanced (LGE) images were acquired after another dose of Gd-DTPA. Results In both PRP, SRP, the myocardial perfusion reserve index (MPRI) was significantly reduced compared with the controls (1.7 ± 0.6 vs 3.5 ± 0.4, p

Background-aim Cardiac involvement at diagnosis of connective tissue disease (CTD) has been described by echocardiography. We hypothesized that cardio-vascular magnetic resonance (CMR) detects occult lesions at CTD diagnosis. Patients-methods CMR was performed early after diagnosis in 78 treatment-naïve CTDs (aged 43 ± 11, 59F/19M) without cardiac involvement [5 Takayasu arteritis (TA), 4 Churg Strauss syndrome (CSS), 5 Wegener granulomatosis (WG), 16 systemic lupus erythematosus (SLE), 12 rheumatoid arthritis (RA), 8 mixed connective tissue diseases (MCTD), 12 ankylosing spondylitis (AS), 3 polymyalgia rheumatica (PMR), 8 systemic sclerosis (SSc) and 5 dermatomyositis (DM)]. Acute and chronic lesions were assessed by T2 > 2 with positive LGE and T2

Background Cardiovascular disease (CVD) has been documented in >50% of systemic lupus erythematosus (SLE) patients, due to a complex interplay between traditional risk factors and SLE-related factors. Various processes, such as coronary artery disease, myocarditis, dilated cardiomyopathy, vasculitis, valvular heart disease, pulmonary hypertension and heart failure, account for CVD complications in SLE. Methods Electrocardiogram (ECG), echocardiography (echo), nuclear techniques, cardiac computed tomography (CT), cardiovascular magnetic resonance (CMR) and cardiac catheterization (CCa) can detect CVD in SLE at an early stage. ECG and echo are the cornerstones of CVD evaluation in SLE. The routine use of cardiac CT and nuclear techniques is limited by radiation exposure and use of iodinated contrast agents. Additionally, nuclear techniques are also limited by low spatial resolution that does not allow detection of sub-endocardial and sub-epicardial lesions. CCa gives definitive information about coronary artery anatomy and pulmonary artery pressure and offers the possibility of interventional therapy. However, it carries the risk of invasive instrumentation. Recently, CMR was proved of great value in the evaluation of cardiac function and the detection of myocardial inflammation, stress-rest perfusion defects and fibrosis. Results An algorithm for CVD evaluation in SLE includes clinical, laboratory, ECG and echo assessment as well as CMR evaluation in patients with inconclusive findings, persistent cardiac symptoms despite normal standard evaluation, new onset of life-threatening arrhythmia/heart failure and/or as a tool to select SLE patients for CCa. Conclusions A non-invasive approach including clinical, laboratory and imaging evaluation is key for early CVD detection in SLE. © The Author(s), 2016.

Objectives: To evaluate the cardiovascular magnetic resonance (CMR) findings in a paediatric population with systemic lupus erythematosus (SLE) and cardiac symptoms. Methods: Twenty-five SLE children, aged 10.2 +/- 2.6 years, with cardiac symptoms and normal routine non-invasive evaluation were examined by CMR, using a 1.5 T system and compared with sex-matched SLE adults. Left ventricular (LV) volumes, ejection fraction, T2 ratio, early (EGE) and late (LGE) gadolinium enhancement were assessed. Acute and chronic lesions were characterised as LGE-positive plus T2 > 2, EGE > 4 or T2 < 2, EGE < 4, respectively. According to LGE, lesions were characterized as: (a) diffuse subendocardial, (b) subepicardial and (c) subendocardial/transmural, due to vasculitis, myocarditis and myocardial infarction, respectively. Results: LV ejection fraction (LVEF) was normal in all SLEs. T2 > 2, EGE > 4 and positive epicardial LGE wall was identified in 5/25 children. Diffuse subendocardial fibrosis was documented in 1/25. No evidence of myocardial infarction was identified in any children. In contrast, in SLE adults, LGE indicative of myocardial infarction was identified in 6/25, myocarditis in 3/25, Libman-Sacks endocarditis in 1/25 and diffuse subendocardial fibrosis in 2/25. The incidence of heart disease in SLE children was lower compared to SLE adults (p < 0.05), with a predominance of myocarditis in children and myocardial infarction in adults. A significant correlation was documented between disease duration and CMR lesions (p < 0.05). Conclusion: CMR identifies a predominance of myocarditis in paediatric SLE with cardiac symptoms and normal routine non-invasive evaluation. However, the incidence of cardiac lesions is lower compared to SLE adults, probably due to shorter disease duration. Significance and Innovation:. CMR identifies heart involvement in a significant percentage of SLE children with cardiac symptoms and normal routine noninvasive evaluation. The incidence of heart disease is lower in SLE children compared with SLE adults. Predominance of myocarditis and myocardial infarction is observed in SLE children and SLE adults, respectively.

Objectives Fibromyalgia (FM) is one of the most common chronic pain syndromes. Various pathogenetic mechanisms have been implicated but none is proven. Our scope was to determine if Intraepidermal Nerve Fiber Density (IENFD) is reduced in the skin of FM patients, as observed in patients with painful small fiber sensory neuropathy (SFSN). Design, setting and participants We prospectively studied 46 FM patients (5 men and 41 women), aged 29 to 76 (mean: 52.5) years, diagnosed according to the ACR 2010 criteria, and 34 controls (18 women and 16 men) aged 19 to 84 (mean: 31.7) years. IENFD was measured using published guidelines and immune markers were sought immunocytochemically. In 30 FM patients, pain intensity was assessed with the Neuropathic Pain Symptom Inventory (NPSI), a scale validated for neuropathic pain. Results 15 of 46 (32.6%) FM patients had reduced IENFD [range: 0.6-12.5 fibers/mm (mean: 4.83 SD: 2.5)], compared to healthy controls [2.8-11.5 fibers/mm (mean: 7.35, SD: 1.85)] (p < 0.0001). No significant correlation was noticed between NPSI scores and IENFD. No difference in the Langerhans cells, the major Antigen Presenting Cells (APCs) in the epidermis, or in IL-6 staining, was noted between FM and controls. IENFD was equally reduced in a subset of FM patients who also had another autoimmune disease. Conclusion This is one of the largest series of FM patients demonstrating a significant reduction of IENFD in their skin biopsies. The findings indicate that in a subset of FM patients, the pain syndrome is, at least partially, of neuropathic origin. Skin biopsy may prove a useful tool and a potential biomarker in future studies of FM patients. © 2014 Published by Elsevier B.V.
