Background:Cardiovascular diseases are becoming the leading cause of death among SLE patients due to increasing life-spans. Transthoracic echocardiography (TTE) is a routine and widely available modality in everyday clinical practice useful to identify specific pathological cardiac changes and predictors of heart failure.Objectives:The goal was to identify potential abnormalities in the TTE findings in SLE patients, with and without antirheumatic therapy.Methods:This is a prospective cross-sectional study including 91pts (91% females, aged 32[28-41]years (median [interquartile range 25%-75%]) with SLE (SLICC 2012 criteria). All patients were divided into 2 groups: the 1st group was composed of “untreated” patients and the 2nd – of patients receiving antirheumatic therapy. The 1st group included 43pts (93% females) aged 31[27–40]years who were not receiving steroids, immunosuppressants and biological agents at the time of enrollment, 5(12%) of them were on hydroxychloroquine (HCQ) therapy 200 mg/day. The 2nd group is represented by 48pts (89% females) with median age 34[28-45]years. Out of them 47(98%) patients were on prednisone therapy at 10[8-15]mg/day, 10(21%)- on cyclophosphamide, 6(13%)-azathioprine, 4(8%)-mycophenolate mofetil, 4(8%)-methotrexate, 37(71%)–HCQ, and 9(19%)–on biologic (rituximab, belimumab). Both groups were matched by age and gender. Patients receiving antirheumatic therapy (group 2) had longer disease duration (96 vs 18 months, p<0,00001), lower disease activity (SLEDAI-2K 4 vs 11 scores, p<0,001), higher SLICC/DI (1 vs 0 score, p<0,001); lower percentage of them had skin lesions (11 vs 57%, p<0,0001), arthritis (22 vs 52%, p<0,05) and hematological disorders (24 vs 74%, p<0,0001) than “untreated” patients from the 1st group.Results:Valve insufficiency with varying degree of clinically insignificant regurgitation and pericarditis were the commonest pathology found in “untreated” and “treated” SLE patients based on TTE data. No differences in rates of valve insufficiency (95% and 83%), pericarditis (43% and 47%) (both exudative and adhesive), endocarditis (26% and 33%), median left ventricular (LV) ejection fraction (64[59-68]% and 64[61-69]%), LV end-systolic dimension (30[27-32]mm and 29[25-31]mm), LV end-diastolic dimension (48[45-50]mm and 45[42-49]mm), pulmonary artery systolic pressure (25[22-31]mm Hg and 23[22-30]mm Hg), LV diastolic disfunction (26% and 21%) and LV systolic dysfunction (9% and 6%), LV myocardial hypertrophy (14% and 21%) and left atrium dilatation (9% and 21%) were found between the “untreated” SLE patients and patients receiving antirheumatic therapy (p>0,05 for all cases). Higher rates of mitral and tricuspid valves prolapse was seen more often in “treatment-naїv” SLE patients: 16(47%) vs 10(21%), p<0,01.Conclusion:Valvular dysfunction (insufficiency with clinically insignificant regurgitation), pericarditis, endocarditis and LVDD were the most common cardiac TTE abnormalities in SLE patients. Antirheumatic therapy seems not to worsen structural and functional cardiac abnormalities based on TTE findings in SLE patients. Only mitral and tricuspid valves prolapse was seen more often in “treatment-naїv” SLE patients.Disclosure of Interests:None declared

Introduction. The actual prevalence of pulmonary hypertension (PH) in Italy is unknown. Echocardiography is useful in the screening of patients with suspected PH by estimation of the pulmonary artery systolic pressure (PASP) from the regurgitant tricuspid flow velocity evaluation, according to the simplified Bernoulli equation. Objectives. We aimed to evaluate the frequency of suspected PH among unselected patients. Methods. We conducted a retrospective cross-sectional database search of 7005 patients, who underwent echocardiography, to estimate the prevalence of PH, between January 2013 and December 2014. Medical and echocardiographic data were collected from a stratified etiological group of PH, using criteria of the European Society of Cardiology classifications. Results. The mean age of the study population was 57.1 ± 20.5 years, of which 55.3% were male. The prevalence of intermediate probability of PH was 8.6%, with nearly equal distribution between men and women (51.3 vs. 48.7%; p = 0.873). The prevalence of high probability of PH was 4.3%, with slightly but not significant higher prevalence in female patients (43.2 vs. 56.8%; p = 0.671). PH is predominant in patients with chronic obstructive pulmonary disease (COPD) or left ventricle (LV) systolic dysfunction and related with age. PASP was significantly linked with left atrial increase and left ventricular ejection fraction. In addition, an increased PASP was related to an enlargement of the right heart chamber. Conclusions. PH has a frequency of 4.3% in our unselected population, but the prevalence may be more relevant in specific subgroups. A larger epidemiological registry could be an adequate strategy to increase quality control and identify weak points in the evaluation and treatment of these patients.

Abstract Funding Acknowledgements Nil Background Left and right ventricular (RV) function is proposed to be intimately linked. Reduced systolic ventricular interaction in patients with reduced global left ventricular (LV) performance is hypothesised to result in a reduction in RV contractile performance, even if the RV is not directly involved in the disease process. Concurrent RV and LV dysfunction is known to carry a poorer prognosis. However, the incidence of RV structural change and systolic dysfunction in patients with LV dysfunction in patients in a clinical setting is not well characterised. Purpose To determine the prevalence of RV systolic impairment in patients with LV systolic impairment from non-ischaemic cardiomyopathy (NICM); and to characterise the relationship between LV and RV systolic function using echocardiographic parameters. Methods 86 consecutive patients with stable heart failure with reduced ejection fraction secondary to NICM without valvular, congenital, and pulmonary disease were recruited. All patients underwent a comprehensive transthoracic echocardiogram and were stratified into tertiles based on LVEF (mild: 40-49%, moderate: 30-39%, severe: &lt;30%). RV function was characterised using standard and novel measures. 2D RV free wall peak systolic strain (RV FWS) was measured using vendor independent software (TomTec Image Arena, Germany v4.6).  Results Of the mild, moderate and severe groups (mean age 58 ± 34, 36% men): mean LVEF (%) was 46 ± 6, 35 ± 6, 22 ± 10 ; mean pulmonary artery systolic pressure (mmHg) was 28 ± 24, 34 ± 31, 38 ± 24; 26%, 79%, 74% had mild or moderate pulmonary hypertension respectively. 33% had RV impairment based on TAPSE of &lt;1.6cm; 48% had RV impairment based on RVS’ of &lt;10cm/s; and 65% had RV impairment based on a FAC of &lt;35%.  Conclusion Whilst there is a concurrent increase in the prevalence of RV impairment with severity of LV systolic impairment, interestingly not all patients with LV dysfunction had RV dysfunction. The presence of RV dysfunction is greatest when measured using FAC and RV FWS. Routine screening of RV dysfunction in patients with HFrEF secondary to NICM may help identify patients with poorer prognosis, who could benefit with more intensive follow up and treatment.

Early Predictor

Background and Aims: Left ventricular systolic dysfunction, even asymptomatic, is associated with the development of heart failure (HF) and all-cause mortality. Left ventricular ejection fraction (LVEF) is the most commonly used marker of left ventricular systolic function. It is well established that early detection and treatment of reduced LVEF, as well as the aggressive management of predisposing conditions, delays the manifestation of HF. Our study aimed to measure the association between LVEF and other echocardiographic variables in a population with LVEF within the normal range and without symptoms of HF. Methods: We conducted a cross-sectional study in 2008-2009. Results: We analyzed echocardiographic and clinical data of 146 patients: 66.4% were women; mean age was 55 (40 –69 years). LVEF significantly correlated only with left atrium (LA) size (Beta -0.266, p < 0.05). The correlation was inverse and remained significant after adjusting for age, gender, obesity, diabetes, arterial hypertension, left ventricular hypertrophy, pulmonary systolic pressure, mitral regurgitation, and diastolic dysfunction. Conclusions: We found that the earliest structural change associated with LVEF tendency to decrease was LA size. Further research is needed to assess the LA enlargement as an early predictor of systolic dysfunction development.

Objective Comparative analysis of structural and functional specific features of the heart in patients with toxic cardiomyopathy (TCMP) with a low left ventricular ejection fraction (LVEF) and severe, chronic heart failure (CHF) and in patients with idiopathic dilated cardiomyopathy (DCMP) and similar LVEF and CHF severity.Materials and Methods This observational, single-site study included 15 patients with TCMP (12 of them received treatment including anthracycline antibiotics and 3 patients received targeted therapies) and 26 patients with idiopathic DCMP. Data of echocardiography were compared for patients with TCMP and DCMP with comparably low LVEF of <40 %.Results In patients with severe heart damage associated with antitumor therapy with low LVEF, volumetric and linear indexes of left and right ventricles and the left atrium (left atrial volume index (LAVI), 33.7 (21.5–36.9) ml / m2; right ventricular end-diastolic dimension (RVDd), 2.49 (1.77–3.53) cm; and end-diastolic volume index (EDVI), 78.0 (58.7–90.0) ml / m2) were considerably less than in the DCMP group (LAVI, 67.1 (51.1–85.0) ml / m2; RVDd, 4.05 (3.6–4.4) cm; and EDVI, 117.85 (100.6–138.5) ml / m2, p<0.0001). Furthermore, LV wall thickness and pulmonary artery systolic pressure did not differ in these groups. Both in men and women with TCMP, LAVI and EDVI were significantly less than in men and women with DCMP.Conclusion The study showed significant differences in parameters of cardiac remodeling. In TCMP patients as distinct from DCMP patients, despite a pronounced decrease in LVEF, LV dilatation was absent or LV volumetric parameters were moderately increased with a more severe somatic status.

Background:Cardiovascular disease (CVD) is detected in up to 50% of systemic lupus erythematosus (SLE) patients1and major cause of death2. Even clinically silent SLE patients can develop left ventricular (LV) diastolic dysfunction3. Proper echocardiographic follow up of SLE patients is required.Objectives:To clarify how the prevalence of LV abnormalities changes over follow-up period and identify the associated clinical factors, useful in suspecting LV abnormalities.Methods:29 SLE patients (24 females and 5 men, mean age 52.8±16.3 years, mean disease duration 17.6±14.5 years) were enrolled. All of them underwent echocardiography as the baseline examination and reexamined over more than a year of follow-up period(mean 1075±480 days) from Jan 2014 to Sep 2019. Patients complicated with pulmonary artery hypertension, deep venous thrombosis or pulmonary embolism and underwent cardiac surgery during the follow-up period were excluded. Left ventricular(LV) systolic dysfunction was defined as ejection fraction (EF) < 50%. LV diastolic dysfunction was defined according to ASE/EACVI guideline4. LV dysfunction (LVD) includes one or both of LV systolic dysfunction and LV diastolic function. Monocyte to HDL ratio (MHR) was calculated by dividing monocyte count with HDL-C level.Prevalence of left ventricular abnormalities was analysed at baseline and follow-up examination. Clinical characteristics and laboratory data were compared among patient groups as follows; patients with LV dysfunction (Group A) and without LV dysfunction (Group B) at the follow-up echocardiography, patients with LV asynergy at any point of examination (Group C) and patients free of LV abnormalities during the follow-up period (Group D).Results:At the baseline examination, LV dysfunction (5/29 cases, 13.8%), LV asynergy (6/29 cases, 21.7%) were detected. Pericarditis was detected in 7 patients (24.1%, LVD in 3 patients, LV asynergy in 2 patients) and 2 of them with subacute onset had progressive LV dysfunction, while 5 patients were normal in echocardiography after remission induction therapy for SLE. At the follow-up examination, LV dysfunction (9/29 cases, 31.0%, 5 new-onset and 1 improved case), LV asynergy (6/29 cases, 21.7%, 2 new-onset and 2 improved cases) were detected. Though any significant differences were observed between Group A and Group B at the baseline, platelet count (156.0 vs 207.0, p=0.049) were significantly lower in LV dysfunction group (Group A) at the follow-up examination. Group C patients had significantly higher uric acid (p=0.004), monocyte count (p=0.009), and MHR (p=0.003) than Group D(results in table).Conclusion:LV dysfunction is progressive in most of patients and requires regular follow-up once they developed. Uric acid, monocyte count and MHR are elevated in SLE patients with LV asynergy. Since MHR elevation was reported as useful marker of endothelial dysfunction5, our future goal is to analyse involvement of monocyte activation and endothelial dysfunction in LV asynergy of SLE patients.References:[1]Doria A et al.

OBJECTIVETo examine a general practice population to measure the prevalence of signs and symptoms of heart failure (SSHF) and left ventricular systolic dysfunction (LVSD).DESIGNCross sectional screening study in three general practices followed by echocardiography.SETTING AND PATIENTSAll patients ⩾ 50 years in two general practices and ⩾ 40 years in one general practice were screened by case record reviews and questionnaires (n = 2158), to identify subjects with some evidence of heart disease. Among these, subjects were sought who had SSHF (n = 115). Of 357 subjects with evidence of heart disease, 252 were eligible for examination, and 126 underwent further cardiological assessment, including 43 with SSHF.MAIN OUTCOME MEASURESPrevalence of SSHF as defined by a modified Boston index, LVSD defined as an indirectly measured left ventricular ejection fraction ⩽ 0.45, and numbers of subjects needing an echocardiogram to detect one case with LVSD.RESULTSSSHF afflicted 0.5% of quadragenarians and rose to 11.7% of octogenarians. Two thirds were handled in primary care only. At ⩾ 50 years of age 6.4% had SSHF, 2.9% had LVSD, and 1.9% (95% confidence interval 1.3% to 2.5%) had both. To detect one case with LVSD in primary care, 14 patients with evidence of heart disease without SSHF and 5.5 patients with SSHF had to be examined.CONCLUSIONSSHF is extremely prevalent in the community, especially in primary care, but more than two thirds do not have LVSD. The number of subjects with some evidence of heart disease needing an echocardiogram to detect one case of LVSD is 14.

Recorded Data

Background: There is a paucity of contemporary Indian data about the prevalence of cardiac abnormalities in patients of connective tissue disorders (CTD) and their risk determinants. Methods: We prospectively recorded data from 35 consecutive CTD patients who presented to our out-patient department and had no significant cardiovascular risk factors at baseline. We also recorded data from their age- and sex-matched controls. All cases and controls were subjected to 12 lead electrocardiogram and echocardiography after routine investigations. Results: The CTD group comprised 19 (54.3%) patients of systemic lupus erythematosus, 12 (34.3%) patients of systemic sclerosis, 2 (5.7%) patients of mixed CTD, and 1 (2.9%) patient each of overlap syndrome and dermatomyositis. Cardiovascular involvement on echocardiography was documented in 71.4% of CTD patients despite majority of them having no cardiac symptom. Overt left ventricular (LV) systolic dysfunction was observed in 3 (8.6%) CTD patients, while subclinical LV systolic dysfunction was recorded in 13 (37.1%) patients. LV diastolic dysfunction was observed in 11.4% (n = 4) patients. RV systolic dysfunction was prevalent in 20% (n = 7) patients. Pulmonary hypertension was observed in 40% (n = 14) of CTD patients. Conclusion: The present study evaluated subclinical LV systolic dysfunction and pulmonary hypertension in about one third of CTD patients. It is imperative to screen for these abnormalities in CTD to ensure timely diagnosis and treatment.

Abstract Background Fabry disease is a rare X-linked storage disorder caused by a deficiency of the lysosomal enzyme α-galactosidase A and generally causes multi-organ dysfunction. Heart disease is the main cause of death, due to severe left ventricular (LV) systolic dysfunction and sudden death. In several heart diseases, the LV systolic dysfunction and ventricular arrhythmias are associated with mechanical dispersion (MD). The presence of MD in patients with FD has not been studied yet. In this cross-sectional study, we investigated the prevalence of MD in patients with FD. Methods Complete echocardiographic and speckle tracking echocardiographic (STE) data were collected. MD is an index of inter-segmental discoordination of contraction which has been used to quantify LV dyssynchrony and was defined as the standard deviation (SD) of time to peak negative strain in 17 left ventricular segments. Patients were divided into two groups according to whether or not they had left ventricular hypertrophy (LVH). MD was defined as an SD >49 msec. Results We studied 108 patients with FD, 24 patients (22%) were excluded due to inadequate imaging quality or presence of comorbidities, so the final study population consisted of 84 patients (mean age 33.3±14.6 years, 60.7% women). LVH in FD appears at older ages than in patients without LVH (48±12.5 y/o vs 27.8±11.1 y/o, p<0.0001). Patients with FD without LVH (Group I) showed normal global longitudinal peak strain (GLPS) (21.2±2.5%) and no MD (32.7±8.8 msec). In Group II (n=23) patients with FD with LVH, 17 (73.9%) had MD >49 msec prolonged mechanical dispersion (73.3±20.7 msec) and reduced GLPS (13.6±4.0%). MD was more pronounced in Fabry patients with LVH than in patients without LVH (63.4±24.7 msec vs. 32.7±8.8 msec, p<0.0001). GLPS was lower in Fabry patients with LVH than in patients without LVH (15.3±4.7% vs 21.2±2.5%, p<0.0001). Figure 1 Conclusions To our knowledge, this is the first study to demonstrate the prevalence of mechanical dispersion in patients with FD. Mechanical dispersion was seen in 73.9% of patients with FD with LVH. This dyssynchrony should be taken into account in patients who develop heart failure or life-threatening ventricular tachyarrhythmias.
