Background: MicroRNA-206 (miR-206), a muscle-specific miRNA, regulates the growth of cardiac myocytes and pulmonary artery smooth muscle cells. However, it remains unknown whether miR-206 is involved in pulmonary hypertension (PH) due to left heart diseases (PH-LHD). This study was designed to investigate the correlation between miR-206 and PH in patients with LHD. Methods: In 82 consecutively enrolled LHD patients, we examined the serum levels of miR-206 and analyzed its correlations with pulmonary artery systolic pressure (PASP) and cardiac function. Another 36 age- and sex-matched subjects served as healthy controls. Results: The patients were divided into the LHD group (n=47, PASP<50 mmHg) and the PH-LHD group (n=35, PASP≥50 mmHg). The level of miR-206 was significantly decreased in the PH-LHD group compared with that of the LHD and healthy control groups. In addition, the miR-206 level was correlated with PASP (r=-0.305, p<0.001) but not with systemic blood pressure. Univariate analyses showed that miR-206, brain natriuretic peptide (BNP), left ventricular ejection fraction and left atrial longitudinal diameter (LAD) were significantly related to PASP. Multivariate regression analysis identified miR-206 as an independent predictive factor for PH. MiR-206 alone (cut-off <0.66) demonstrated a sensitivity of 68.60% and a specificity of 65.80% in predicting PH. Moreover, the combination of miR-206, BNP and LAD (cut-off 0.21) showed a sensitivity of 97.10% and a specificity of 80.30% in predicting PH in LHD patients. Conclusion: A decreased circulating miR-206 level was associated with increased PASP in LHD patients. Thus, the level of miR-206, especially combined with BNP and LAD, might be helpful in the detection of PH in LHD patients.

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 Introduction Pulmonary hypertension (PHT) associated with thalassemia hemoglobinopathy is now an accepted clinical entity. Due to a high prevalence of thalassemia hemoglobinpathy worldwide, it is the most common entity of PHT. Despite the commonness, its pathogenesis is not yet completely understood. Although asplenia is a known risk factor, PHT does not develop in all splenectomized patients. The present study was therefore done to search for other associated features. Patients and Methods Sixty-one clinically stable splenectomized hemoglobin E/β-thalassemia disease (E/β-Thal) adult outpatients, on no medication aside from folic acid and who received no blood transfusion in the preceding 4 weeks, were prospectively studied. All gave written informed consent, and study protocol was approved by the institution ethics committee on studies in humans (#0774/2548). Transthoracic echocardiogram was used to evaluate cardiac function and to estimate pulmonary artery systolic pressure (PASP). PHT was defined as an estimated PASP ≥36 mmHg. Clinical features and laboratory data were dichotomized according to the presence (PHT+) or absence (PHT-) of PHT, and statistical analysis was done by STATA version 10 (Stata Corp, Texas), considering a P value<0.05 as statistically significant. Results Of the 61 patients, 32 (52.5%) were PHT+, 14 of whom were female. There was no gender difference between the 2 groups (p=0.246). All had normal left ventricular ejection fraction, and none had positive serology for human immunodeficiency virus. Results expressed in mean ± SD or median (range) of the various measured parameters and their statistically significant differences are shown in the following table. Conclusions PHT was found in 52.5% of the 61 splenectomized E/β-Thal patients with no gender preponderance. Although PHT was found mostly after the first decade of splenectomy, its prevalence did not correlate with time elapsed since the procedure. Features associated with PHT in splenectomized E/β-Thal patients were greater transfusion requirement, lower RBC counts, higher serum lactate dehydrogenase (LDH) and lower serum cholesterol levels, as a reflection of more severe disease and more severe ineffective erythropoiesis; together with a higher serum soluble vascular cell adhesion molecule-1 (VCAM-1) levels, likely from chronic hypoxemia. Disclosures: No relevant conflicts of interest to declare.

As of now, there has been a great body of data on the use of rituximab (RTM) in systemic sclerosis (SS), mainly on its positive effect on skin fibrosis and lung injury. However, information is still scarce about the effect of RTM on other organs and systems, namely the heart affected by SS.Objective: to assess the time course of changes in the signs of heart involvement in SS patients one year after initiation of RTM therapy.Subjects and methods. The paper gives data on changes in cardiac disorders in 71 patients with SS one year after the prescription of RTM.Results and discussion. The rate of cardiac rhythm and conduction disorders and diastolic dysfunction was unchanged. At the same time, a significant increase in left ventricular ejection fraction (EF) and a reduction in the severity of dyspnea was achieved, which correlated with improved lung function (a significant rise in forced vital capacity). The results of treatment in three patients with predominant heart involvement associated with SS (coronary heart disease and hypertension were ruled out) were considered in detail. These patients displayed pronounced positive changes as increased EF, less severe cardiac arrhythmias, reduced chronic heart failure, better quality of life, as well as the synchronicity of lower disease activity, less skin induction, improved lung function, and stabilized pulmonary artery systolic pressure.Conclusion. RTM in combination with traditional therapy can be considered as a potentially effective drug for the treatment of heart involvement in SS.

Abstract Background  Dyspnoea is very common in elderly patients and can be caused by a variety of different diseases. However, the initial diagnosis of patent ductus arteriosus (PDA) as a cause of left heart failure is very rare in this patient population. Case summary  A 69-year-old physically active woman with known hypertension presented with worsening exertional dyspnoea. Echocardiography showed a dilated left ventricle with moderately reduced left ventricular ejection fraction, and evidence for PDA. The PDA was confirmed by computed tomography angiography and successfully closed by implantation of an Amplatzer PDA occluder II 06-06 mm. As a result, the heart failure symptoms receded completely. Discussion  Congenital heart diseases should be considered as heart failure causes even in older adults. In addition to the standard medical therapy, there may be effective interventional treatment options to reverse the symptoms of heart failure in such patients.

Purpose. To design a mathematical model, that can predict a positive response to cardiac resynchronization therapy (CRT) in patients with congestive heart failure (CHF) and sinus rhythm, according to complex analysis of neurohumoral and immune activation biomarkers, fibrosis, renal dysfunction, echocardiography.Methods. Parameters of echocardiography, plasma levels of NT-proBNP, interleukins-1β, 6, 10, tumor necrosis factor α, С-reactive protein (СRP), matrix metalloproteinase-9 (ММР-9), tissue inhibitors of metalloproteinase 1 and 4, cystatin С (CYSTATIN) were studied in 40 CHF patients with sinus rhythm (65% coronary artery disease patients, 75% males, mean age 54.8±10.6 years old) during the period of maximum decrease of left ventricular end-systolic volume (LVESV) (mean duration 27.5 [11.1; 46.3] months). Responders (decrease in LVESV ≥15%) and non-responders (decrease in LVESV <15%) were identified.Results. The number of responders was 26 (65%). The initial set of variables included: age, left ventricular ejection fraction (EF), pulmonary artery systolic pressure, right ventricle size and NT-proBNP, СRP, ММР-9, CYSTATIN. According to logistic regression analysis, a prediction model of positive CRT response was created. The specificity of the model was 92.9%, sensitivity - 83.3%, AUC=0.952 (р˂0.001).Conclusion. The proposed model, based on the assessment of left ventricle EF and circulating biomarkers of inflammation, fibrosis, and renal function, strongly suggests a higher possibility of response to CRT.

Abstract Aims Quantitative echocardiography parameters are seldom used to grade tricuspid regurgitation (TR) severity due to relative paucity of validation studies and lack of prognostic data. To assess the relationship between TR severity and the composite endpoint of death and hospitalization for congestive heart failure (CHF); and to identify the threshold values of vena contracta width (VCavg), effective regurgitant orifice area (EROA), regurgitant volume (RegVol), and regurgitant fraction (RegFr) to define low, intermediate, and high-risk TR based on patients’ outcome data. Methods and results A cohort of 296 patients with at least mild TR underwent 2D, 3D, and Doppler echocardiography. We built statistical models (adjusted for age, NYHA class, left ventricular ejection fraction, and pulmonary artery systolic pressure) for VCavg, EROA, RegVol, and RegFr to study their relationships with the hazard of outcome. The tertiles of the derived hazard values defined the threshold values of the quantitative parameters for TR severity grading. During 47-month follow-up, 32 deaths and 72 CHF occurred. Event-free rate was 14%, 48%, and 93% in patients with severe, moderate, and mild TR, respectively. Severe TR was graded as VCavg &gt; 6 mm, EROA &gt; 0.30 cm2, RegVol &gt; 30 mL, and RegF &gt; 45%. Conclusion This outcome study demonstrates the prognostic value of quantitative parameters of TR severity and provides prognostically meaningful threshold values to grade TR severity in low, intermediate, and high risk.

ObjectivesTo evaluate the prognostic value of the ratio between tricuspid annular plane systolic excursion (TAPSE)-pulmonary artery systolic pressure (PASP) as a determinant of right ventricular to pulmonary artery (RV-PA) coupling in patients undergoing transcatheter aortic valve replacement (TAVI).BackgroundRV function and pulmonary hypertension (PH) are both prognostically important in patients receiving TAVI. RV-PA coupling has been shown to be prognostic important in patients with heart failure but not previously evaluated in TAVI patients.MethodsConsecutive patients with severe aortic stenosis who received TAVI from July 2011 through January 2016 and with comprehensive baseline echocardiogram were included. All individual echocardiographic images and Doppler data were independently reviewed and blinded to the clinical information and outcomes. Cox models quantified the effect of TAPSE/PASP quartiles on subsequent all-cause mortality while adjusting for confounders.ResultsA total of 457 patients were included with mean age of 82.8±7.2 years, left ventricular ejection fraction (LVEF) 54%±13%, PASP 44±17 mm Hg. TAPSE/PASP quartiles showed a dose-response relationship with survival. This remained significant (HR for lowest quartile vs highest quartile=2.21, 95% CI 1.07 to 4.57, p=0.03) after adjusting for age, atrial fibrillation, LVEF, stroke volume index, Society of Thoracic Surgeons Predicted Risk of Mortality.ConclusionBaseline TAPSE/PASP ratio is associated with all-cause mortality in TAVI patients as it evaluates RV systolic performance at a given degree of afterload. Incorporation of right-side unit into the risk stratification may improve optimal selection of patients for TAVI.

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.
