This study evaluated the correlation between interatrial block (IAB) and atrial fibrillation (AF) among patients admitted to our Internal Medicine Unit: 110 (group 1) were identified with electrocardiograms both in sinus rhythm and AF, and 123 (group 2) constantly in sinus rhythm. In both groups we analyzed: the presence of partial (P≥120 msec) or advanced (P>120 msec and biphasic in D2, D3, aVF) IAB, and the main electrocardiographic and clinical features. Age and gender between the two groups were similar. IAB was present in 89/110 (80.91%) in group 1 and 26/123 (21.13%) in group 2 (P=<0.01); partial in 50/110 (45.45%) and 19/123 (15.7%) in group 1 and 2 respectively (P<0.01), advanced in 39/110 (35.45%) and 7/123 (5.69%) (P<0.019). The correlation between IAB and AF was significant (P<0.001); 36 (65.4%) patients out of 55 with atrial echo dilatation had IAB and 14 (25.4%) had deep terminal negativity of P-wave in V1 (DTNPV1) >0.1 mV (P<0.01). IAB represents a reliable predictor of AF; moreover, the sensitivity of the IAB in detecting atrial dilatation is higher than the DTNPV1 >0.1 mV.

Abstract Background Advanced interatrial block (IAB), prolonged and bimodal P waves in surface ECG inferior leads, is an unrecognized surrogate of atrial dysfunction and a trigger of atrial dysrhythmias, mainly atrial fibrillation (AF). Our aim was to prospectively assess whether advanced IAB in sinus rhythm precedes AF and stroke in elderly outpatients with structural heart disease, a group not previously studied. Methods Prospective observational registry that included outpatients aged ≥70 years with structural heart disease and no previous diagnosis of AF. Patients were divided into three groups according to P-wave characteristics. Results Among 556 individuals, 223 had normal P-wave (40.1%), 196 partial IAB (35.3%), and 137 advanced IAB (24.6%). After a median follow-up of 694 days; 93 patients (16.7%) developed AF, 30 stroke (5.4%), and 34 died (6.1%). Advanced IAB was independently associated with AF (hazard ratio [HR] 2.9, 95% confidence interval [CI] 1.7–5.1, p&lt;0.001), stroke (HR 3.8, 95% CI 1.4–10.7, p=0.010), and AF/stroke (HR 2.6, 95% CI 1.5–4.4, p=0.001). P-wave duration (ms) was independently associated with AF (HR 1.05, 95% CI 1.03–1.07, p&lt;0.001), AF/stroke (HR 1.04, 95% CI 1.02–1.06, p&lt;0.001), and mortality (HR 1.04, 95% CI 1.00–1.08, p=0.021). Conclusions The presence of advanced IAB in sinus rhythm is a risk factor for AF and stroke in an elderly population with structural heart disease and no previous diagnosis of AF. P-wave duration was also associated with all-cause mortality. Figure.

Objective: To perform morphometric analysis of corpus callosum (CC) by using callosal area (CA), supratentorial-supracallosal area (SSA) and CA/SSA parameters in a healthy pediatric population and to investigate changes according to age and gender. Method: Method: This retrospective study included a total of 313 children (154 boys, 159 girls) aged between 3-17 years. The cases were divided into three groups according to age: 3-6 years (Group 1) (pre-school), 7-12 years (Group 2) (preadolescent) and 13-17 years (Group 3) (adolescent). CA and SSA were measured on the mid-sagittal plane on T1-weighted images. CA/ SSA index was calculated. Differences in age, CA, SSA, and ratio parameters among the gender groups were compared using the Mann-Whitney U or the t-test. Results: Median values of CA (p= 0.002), mean values of SSA (p=0.001) and CA/SSA ratios (p= 0.04) were significantly higher in boys compared to girls. The median CA and mean CA/SSA ratios in Group 3 were significantly higher than Groups 1 and 2 (p= 0.001). Mean CA/SSA ratio values of boys and girls in Age Group 3 were significantly higher than Group 1 (p= 0.001) and significantly higher than Age Group 2 in girls. There were highly significant positive correlations of age with CA (p=0.001, r=0.47), SSA (p=0.028, r=0.12) and CA/SSA ratio (p=0.001, r=042). There was a highly significant and positive correlation between CA and SSA (p=0.001, r=0.25) and CA/SSA ratio (p=0.001, r=0.87). Conclusion: CA, SSA, and CA/ SSA ratio values in children are affected by age and gender. These parameters can be used as reference values for the diagnosis of congenital and acquired pathologies affecting the corpus callosum.

Aim. To evaluate the dynamics of left atrial volume (LAV), strain (S) during the reservoir phase and strain rate (SR) in patients with paroxysmal and persistent atrial fibrillation (AF), scheduled for catheter radiofrequency ablation (RFA), as well as to compare the predictive value of S and SR as a marker of maintaining sinus rhythm.Material and methods. A total of 19 patients (men, 11; women, 8) aged 62±10,7 years with AF were included in the study, 13 (67%) of whom had persistent AF, while 6 patients (33%) had paroxysmal AF Two-dimensional and speckle tracking N. Sh. echocardiography (EPIQ 7, Philips) were performed in all patients before ablation and 12 months after RFA.Results. The patients were divided into 2 groups: group 1 — no recurrent AF after RFA (n=12; 63%); group 2 — recurrent AF after RFA (n=7; 37%). According to 2D echocardiography, the baseline values of LAV and LAV index (LAVI) did not significantly differ between groups 1 and 2: 56,0±12,6 ml and 52,0±23,2 ml (p=0,78); 28,0±7,8 ml/m2 and 25,1±13,6 ml/m2 (p=0,85), respectively. The initial S values of the LA in the four-chamber (4C-) and two-chamber (2C-) apical views in group 1patients were higher than in those from group 2: 4C-S, 34,3±9,9% and 16,9±4,4% (p=0,0008); 2C-S, 29,2±8,3% and 14,5±4,4% (p=0,0011), respectively. Baseline SR values were higher in group 1 patients compared with group 2 in 4C- and 2C-views: 4C-SR, 2,36±0,37 s-1 and 1,39±0,50 s-1 (p=0,0013); 2C-SR 2,09±0,39 s-1 and 1,4±0,53 s-1 (p=0,0053), respectively. The LAV in group 1 became significantly less after RFA than its initial levels: 56,0±12,6 ml and 47,0±12,1 ml (p=0,008). The LAVI also significantly decreased 12 months after RFA as follows: 28,0±7,8 ml/m2 and 22,6±8,3 ml/m2 (p=0,02). In group 2, there was no decrease in either LAV or LAVI after 12 months: LAV, 52,0±23,2 ml and 54,0±12,1 ml (p=1,0); LAVI, 25,1±13,6 ml/m2 and 30,9±7,6 ml/m2 (p=0,3). In group 1, there was no significant change in LA S 12 months after RFA: 4C-S, 34,3±9,9% and 30,3±9,6% (p=0,287); 2C-S, 29,2±8,3% and 28,9±9,1% (p=0,82). In group 2, LA S levels in 4C- and 2C-views did not significantly change depending on the performed RFA procedure: 4C-S, 16,9±4,4% and 17,4±6,2% (p=0,12); 2C-S, 14,5±4,4% and 16,5±6,8% (p=1,0). According to the ROC analysis, the optimal cut-off values for baseline 4C-SR (1,8 s-1 (AUC=0,958)), 2C-SR (1,75 s-1 (AUC=0,899)), 4C-S (20,7% (AUC=0,976)), and 2C-S (19,2% (AUC=0,964)) were reliable individual predictors of sinus rhythm maintenance.Conclusion. A stable sinus rhythm 12 months after the RFA was maintained in patients with higher baseline LA S and SR levels. The baseline LA S and SR values have a high predictive value for AF recurrence in patients after RFA. In patients with effective RFA, LAV and LAVI decreased without changing the S and SR. There was no effect of LA reverse remodeling and improvement in LA S values in patients with recurrent AF after RFA.

Between 1995 and 1997, 180 patients who had undergone coronary artery bypass grafting were given intravenous diltiazem for conversion of supraventricular tachycardia to sinus rhythm or control of ventricular rhythm in atrial fibrillation. The patients were divided into three groups of 60 each: group 1 required no inotropic support; group 2 had mild inotropic support with dopamine; group 3 had high-dose inotropic support with adrenalin and dopamine. Thirty-eight patients in group 1 (63%), 40 in group 2 (67%), and 32 in group 3 (53%) responded to one or two doses of diltiazem. There was no difference between the groups in terms of the success rate of the treatment (p > 0.05). Additional procedures were needed in 70 patients including cardioversion in 20 (12 in group 1, 8 in group 2). Mean cardiac index was significantly increased and mean pulmonary artery pressure was significantly decreased in all three groups after diltiazem treatment. After the first dose of diltiazem (0.25 mg·kg−1), the mean heart rate decreased from 141.5mg·kg−1 ± 3.8, 136.9 ± 8.5, and 140.2 ± 4.7 to 118.2 ± 5.1, 101.2 ± 6.7, and 105.6 ± 16.8 in groups 1, 2, and 3, respectively. The maximum decrease was seen after 5 minutes. After the second dose of diltiazem (0.35 mg·kg−1), although mean heart rates were not significantly decreased, 45% of group 1, 44% of group 2, and 46% of group 3 patients who did not respond to the first dose of diltiazem, converted to sinus rhythm. In the early postoperative period after coronary artery bypass graft surgery, diltiazem was of benefit in the treatment of supraventricular tachycardia and atrial fibrillation or flutter. This treatment may be especially useful in patients who are in poor hemodynamic condition.

Objective To determine the aetiology and influence of age and gender on the development of advanced chronic venous insufficiency in patients of semi-urban county outpatient vascular clinic. Methods One hundred and fourteen patients with venous ulcers were divided, based on the ultrasound examination, into group 1 or group 2, with or without post-thrombotic lesions in the deep venous system, respectively. The control group consisted of 352 patients with varicose veins and without leg ulceration. The demographic data and thrombotic risk factors were compared between the groups. Results Group 1 patients ( n = 109) were older than group 2 patients ( n = 5) and control group patients, 64.7 versus 47.2 years ( P = 0.016) and versus 53.8 years ( P < 0.001), respectively. The percentage of women did not differ between group 1 and the control group, but was lower in group 2 ( P = 0.01). The history of lower limb fracture or severe trauma increased the risk of post-thrombotic syndrome (PTS) in patients with venous ulcer. Conclusion In the population studied, the venous leg ulcer develops mainly due to primary varicose veins and its risk increases with age and is equal for both sexes. PTS should be suspected in younger patients with a history of severe trauma or leg fracture.

Abstract Aims Advanced interatrial block (IAB), is an unrecognized surrogate of atrial dysfunction and a trigger of atrial dysrhythmias, mainly atrial fibrillation (AF). Our aim was to prospectively assess whether advanced IAB in sinus rhythm is associated with AF and stroke in elderly outpatients with structural heart disease, a group not previously studied. Methods and results Prospective observational registry that included outpatients aged ≥70 years with structural heart disease and no previous diagnosis of AF. Patients were divided into three groups: normal P-wave duration (&lt;120 ms), partial IAB (P-wave duration ≥120 ms, positive in the inferior leads), and advanced IAB [P-wave duration ≥120 ms, biphasic (plus/minus) morphology in the inferior leads]. Among 556 individuals, 223 had normal P-wave (40.1%), 196 partial IAB (35.3%), and 137 advanced IAB (24.6%). After a median follow-up of 694 days, 93 patients (16.7%) developed AF, 30 stroke (5.4%), and 34 died (6.1%). Advanced IAB was independently associated with AF –[hazard ratio (HR) 2.9, 95% confidence interval (CI) 1.7–5.1; P &lt; 0.001], stroke [HR 3.8, 95% CI 1.4–10.7; P = 0.010), and AF/stroke (HR 2.6, 95% CI 1.5–4.4; P = 0.001). P-wave duration (ms) was independently associated with AF (HR 1.05, 95% CI 1.03–1.07; P &lt; 0.001), AF/stroke (HR 1.04, 95% CI 1.02–1.06; P &lt; 0.001), and mortality (HR 1.04, 95% CI 1.00–1.08; P = 0.021). Conclusions The presence of advanced IAB in sinus rhythm is independently associated with AF and stroke in an elderly population with structural heart disease and no previous diagnosis of AF. P-wave duration was also associated with all-cause mortality.

Abstract Background Atrial electromechanical delay, assessed calculating the PA-TDI interval using tissue Doppler imaging, is a known and promising determinant for atrial fibrillation recurrence prediction after pulmonary vein isolation and electrical cardioversion. Purpose To determine the relationship between atrial electromechanical delay and the presence of atrial fibrillation. Methods We prospectively enrolled patients presenting at our Unit in sinus rhythm scheduled for an arrhythmogenic substrate ablation (atrial fibrillation -AF-, supraventricular tachycardia -SVT- and premature ventricular contractions -PVC-). Demographic and echocardiographic characteristics were evaluated upon admission. Atrial electromechanical delay was inferred via the PA-TDI interval, obtained by calculating the time difference between the P wave onset and the A" wave peak on TDI recordings. Results From October 2018 to August 2019, 200 patients (60% male, mean age 58,21 ± 14,26, mean BSA 1,9 ± 0,21 m2, mean BMI 26,42 ± 6,28 kg/m2, mean EF 60,91% ± 5,43%) were admitted to our unit to undergo AF (group 1: n = 145; 72,50%), SVT or PVC ablation (group 2: n = 55; 27,5%). Compared with the control group (group 2), patients admitted for AF ablation had a larger LA size (group 1 vs group 2: mean LA area 23,21 ± 5,07 vs 16,87 ± 4,01 cm2, p &lt; 0,001; mean indexed LA volume 46,71 ± 20,41 ml vs 32,04 ± 14,7 ml, p &lt; 0,001; mean LAD 41,77 ± 5,66 vs 33,84 ± 6,06, p &lt; 0,001) and a longer PA-TDI interval (lateral 148,55 ± 28,5 vs 128,57 ± 20,9, p &lt; 0,001; medial 125,34 ± 21,02 vs 109,11 ± 21,49, p &lt; 0,001; average 141,43 ± 27,58 vs 119,08 ± 18,63, p &lt; 0,001). Conclusion The PA-TDI interval is a non-invasive and easily achievable echocardiographic parameter, which is demonstrated to be prolonged in patients with a history of AF in contrast with patients with other arrhythmias, as expression of atrial conduction heterogeneity.

Abstract PURPOSE Left atrial (LA) fibrosis is the hallmark of LA remodeling in atrial fibrillation (AF), alters LA function and may predict poor catheter ablation (CA) outcome. LA fibrosis may be assessed invasively using electroanatomical mapping (EAM) during electrophysiological study. The aim was to assess LA function parameters in relation to degree of LA fibrosis derived from EAM in patients with AF. METHODS Patients (pts) n = 39 (79% males, mean age 56+/-10) with non-valvular AF were studied with TTE and TEE before first CA during sinus rhythm. LA strain (LAS) and strain rate (LASR) were analyzed in reservoir (r), conduit (cd) and contractile (ct) phases. The velocities of mitral A, E" and A" were measured with Doppler. E/E" and LA stiffness index - the ratio of E/E" to LASr were assessed. LA appendage flow velocity (LAAv) was measured in TEE. LA volume using biplane area-length method was calculated. The EAM of LA was build using Carto System before CA. Low amplitude potentials area (LAPA) was quantitatively analyzed and expressed as a percentage of LA surface using the cut-off &lt;0.5 mV to detect sites of fibrosis. LA parameters were compared between mild (LAPA &lt;10%) moderate (LAPA 10-40%) and extensive degree of LA fibrosis (LAPA &gt;40%) (table). RESULTS The mean LA volume was 35 ± 11 mL/m². The LAPA ranged from 2 to 78 % of LA surface. Reduced LA function was observed in the LAPA &gt;40% group. Extensive LAPA altered mainly LA compliance parameters. Traditional LA systolic function parameters did not differ in relation to degree of LAPA. CONCLUSION LA compliance is mostly affected by LA fibrosis, thus LA diastolic parameters may be useful in the noninvasive assessment of LA fibrosis. Whether these parameters should be a part of the proper selection of candidates for CA requires further studies.

Abstract Background Mental disorders in patients with cardiovascular disease have a significant impact on the course, the prognosis of the underlying disease and quality of life (QOL). Objective We aimed to examine the prevalence of anxiety and depressive disorders and their impact on the quality of life in patients with atrial fibrillation (AF). Materials and methods In 52 with permanent AF and 50 with paroxysmal AF patients, we administered the depression scale Tsung, the scale of situational anxiety (SA) and personal anxiety (PA) Spielberger-Hanin; QOL was assessed the SF-36 quality of life assessment scale. Correlation analysis using Spearman's rank correlation coefficient. Results The prevalence symptoms mild depression situational or neurotic genesis was 21.1% (12 patients) in Group 1 and 12.0% (6 patients) in Group 2 (p&gt;0.05). Subdepressive state was two percents of patients in Group 1 and Group 2. The incidence SA was 59.6% (31 patients) in Group 1 and 52.0% (26 patients) in Group 2. The incidence PA was 74.0% (37 patients) in Group 2 and 67.3% (35 patients) in Group 1. The average score the physical component of health (PCH) was 29,8±4,3 in Group 1, the mental component of health (MCH) – 49.5±7.4 points; p&lt;0.05. In Group 2: PCH – 44.8±6.6 points, MCH – 26.6±7.5 points; p&lt;0.05. Correlation analysis showed negative strong correlations between SA and MCH (r=−0.64, p=0.0005) and between PA and MCH (r=−0.69, p&lt;0.0001), between SA and PCH (r=−0.71, p=0.0001), between depression and PCH (r=−0.69, p=0.023). Negative statistically significant correlation between depression and MCH (r=−0.69, p=0.54) and negative medium correlation between depression and PCH (r=−0.64, p=0.23). Conclusion These findings suggest that we did not identify patients with symptoms of a true depressive (that can cause pseudodementia and influenced to complete tests). 16.5% patients with AF had mild depression of situational or neurotic genesis. Depression may be a pathogenetic factor of AF or develop because of paroxysms AF – psychological stress. More than 50% patients in Group 1 and Group 2 had an increased anxiety score. SA is more common in patients with permanent AF, probably because older people difficult to adapt to a new situation. PA is more common in patient with paroxysmal AF, probably because disease is sudden and causes anxiety. The PCH of QOL is more impairment in patients with permanent AF, because complications (for example heart failure) impairment physical activity. However, PCH also reduced in patient with paroxysmal AF, because disease is sudden may occur during physical activity. The MCH of QOL is more impairment in patients with paroxysmal AF, because waiting attack effect on mental health and social functioning. An increased level of anxiety and depression negatively affected the mental and physical health of patients with AF. Funding Acknowledgement Type of funding source: None

Background:Idiopathic inflammatory myopathies are a heterogenous group of systemic autoimmune diseases. Several phenotypes have been linked to specific autoantibodies. Clinically amyopathic dermatomyositis with rapidly progressive interstitial lung disease, the most severe form of ILD, is associated with the anti-MDA5 antibodies. However not all the patients with dermatomyositis and anti-MDA5 positive antibodies develop this severe condition.Objectives:We aim to define different phenotypes from a large cohort of patients diagnosed with dermatomyositis who were positive to anti-MDA5 antibodies.Methods:We retrospective analyzed the clinical and immunological data of 90 anti-MDA5 patients [50 female, 55.6%, mean (SD) age at diagnosis 47 (15.4) yrs.] with dermatomyositis recruited from a multicenter register in Spain (MEDRA5) including 30 hospitals. All the patients fulfill de International Myositis Classification Criteria (EULAR/ACR) for dermatomyositis (score >90%). Anti-MDA5 were detected by means of commercial immunoblot (EUROIMMUN©). The chi-square test was used to assess the relationships between qualitative variables. The Kruskal-Wallis test was used to compared medians between groups.Results:Sixty-six patients (73.3%) were diagnosed with clinically amyopathic dermatomyositis. Three different phenotypes linked with the anti-MDA5 antibody were identified. Group 1: patients with rapidly-ILD phenotype (28 patients, 31.1%), group 2: antisynthetase-like phenotype (23 patients, 25.5%), and group 3: non-ILD phenotype (39 patients, 43.3%). Clinical and immunological comparison between the groups disclosed that age at disease onset was higher (median, IQR) in patients from group 1 [53 (43-60)] vs. group 2 [46 (40-56)] or group 3 [42(41-51)] (p=0.01); disease onset was more frequent in spring in patients from group 1 (46.5%) than in the rest of the groups (21.7% and 28.9%) (p<0.01). Cancer was detected in 7 patients, only associated with myositis in 3 cases (3 years interval between cancer and dermatomyositis) without significant differences between phenotypes. Vasculitis (one case ANCA positive) was detected in 9 cases (6 limited to skin, 1 renal and 1 intestinal), 6 of them in the group 3 (statistical significance, in comparison with group 1 and 2, p<0.01). Mortality rate was higher in group 1 (51.9%, 16 out of 17 due to refractory respiratory failure) vs group 2 (12.5%) or 3 (0%) (p<0.001). Anti Ro52 positivity was more frequent in group 1 (65.4%) vs. group 2 (25%) or 3 (35.5%) (p<0.017), although it did not reach statistical significance in terms of mortality (p=0.173) or patients admitted in the intensive care unit (p=0.173). Mechanic hands were more frequent in group 2 (40.6%) than in groups 1 (25%) and 3 (34.4%) (p=0.05). Fever was significantly most frequent in group 1(52.6%) than in group 2 (21.1%) and 3 (26.3%) (p=0.001). Other clinical or immunological features such as arthritis, myositis, or the number of characteristic skin lesions among others were not more frequent in one group or another.Conclusion:Three different phenotypes of patients positive to anti-MDA5 were identified. The presence or not of ILD, or the different type (rapidly progressive or not) of ILD were the main feature that allow to differentiate these phenotypes, which are relevant in clinical practice.References:[1]Allenbach Y, Uzunhan Y, Toquet S, et al; French Myositis Network.
