Heart failure (HF) is associated with morbidity and mortality. Real-time three-dimensional echocardiography (RT3DE) may offer additional prognostic data in patients with HF. The study aimed to evaluate the prognostic value of real-time three-dimensional echocardiography (RT3DE). This is a prospective study that included 89 patients with HF and left ventricular ejection fraction (LVEF) < 0.50 who were followed for 48 months. Left atrium and ventricular volumes and functions were evaluated by RT3DE. TDI and two-dimensional echocardiography parameters were also obtained...

BACKGROUND: Pulmonary hypertension is a common complication of rheumatic mitral stenosis (MS). Patients with similar mitral valve (MV) areas may have different pulmonary artery pressures. Net atrioventricular compliance (Cn) was found to play an important role in the development of pulmonary hypertension. AIM: To test the value of Cn in predicting persistent pulmonary artery hypertension (PPAH) after percutaneous mitral balloon commissurotomy (PMBC). PATIENTS AND METHODS: Eighty patients with severe MS, suitable for PMBC were included in the study...

INTRODUCTION: Pulmonary arterial hypertension (PAH) is an increasingly recognized complication of systemic lupus erythematous (SLE), which may remain undiagnosed if asymptomatic. OBJECTIVE: This study aimed to determine the correlation between echocardiographic findings of PAH and six-minute walk test (6WMT) and serum pro b-type natriuretic peptide (proBNP) level in patients with SLE. METHODS: This cross-sectional study was performed on 50 SLE patients selected from patients referring to the outpatient's department of the Rheumatology Clinic at Imam Reza Hospital in Mashhad, Iran, from July 2013 through September 2014, using resting transthoracic echocardiography to estimate systolic pulmonary artery pressure (sPAP)...

In vitro and animal studies revealed miRs to be involved in modulation of hypoxia-induced pulmonary hypertension (HPH). However, knowledge on circulating miRs in humans in the context of HPH is very limited. Since symptoms of HPH are non-specific and non-invasive diagnostic parameters do not exist, a disease-specific and hypoxemia-independent biomarker indicating HPH would be of clinical value. To examine whether plasma miR levels correlate with hypoxia-induced increase in pulmonary artery pressures, plasma miRs were assessed in a model of hypoxia-related pulmonary hypertension in humans exposed to extreme altitude...

Dental caries, which affects billions of people, is a chronic infectious disease that involves Streptococcus mutans, which is nevertheless a poor predictor of individual caries development. We therefore investigated if adhesin types of S.mutans with sucrose-independent adhesion to host DMBT1 (i.e. SpaP A, B or C) and collagen (i.e. Cnm, Cbm) match and predict individual differences in caries development. The adhesin types were measured in whole saliva by qPCR in 452 12-year-old Swedish children and related to caries at baseline and prospectively at a 5-year follow-up...

BACKGROUND: Studies comparing biventricular (BiV) cardiac resynchronization therapy (CRT) and left ventricular (LV) pacing alone have yielded conflicting results. We recently reported the results of the Greater Evaluation of Resynchronization Therapy for Heart Failure (GREATER-EARTH) trial demonstrating similar clinical benefits of BiV and LV-CRT on exercise tolerance. We report the prespecified secondary outcomes of the GREATER-EARTH trial, comparing the impact of BiV vs LV-CRT on structural and biochemical cardiac remodelling...

Remote ischemic preconditioning (RIPC) has been shown to protect remote organs, such as the brain and the lung, from damage induced by subsequent hypoxia or ischemia. Acute mountain sickness (AMS) is a syndrome of non-specific neurologic symptoms and in high altitude pulmonary edema excessive hypoxic pulmonary vasoconstriction (HPV) plays a pivotal role. We hypothesized that RIPC protects the brain from AMS and attenuates the magnitude of HPV after rapid ascent to 3450 m. Forty non-acclimatized volunteers were randomized into 2 groups...

The effect of percutaneous mitral valve repair using the MitraClip system on tricuspid regurgitation (TR) has not been well investigated. We retrospectively analyzed 102 consecutive patients who underwent the successful MitraClip procedure, and who also had a preprocedural and 1-year follow-up transthoracic echocardiography. TR severity was graded by standard guideline-recommended criteria. At 1 year after the MitraClip procedure, the degree of TR regressed (at least 1 grade) in 23% of the patients, was unchanged in 62% of the patients, and progressed in 16% of the patients...

Aortic valve stenosis (AVS) is associated with significant myocardial fibrosis (MF). Global longitudinal strain (GLS) is a sensible indicator of systolic dysfunction. ST2 is a member of the interleukin (IL)-1 receptor family and a modulator of hypertrophic and fibrotic responses. We aimed at assessing: (a) the association between adverse LV remodeling, LV functional parameters (including GLS) and sST2 level. (b) The association between MF (detected by endo-myocardial biopsy) and sST2 in patients with AVS undergoing surgical valve replacement...

BACKGROUND: The quantification of hypoxia based on resting partial pressure of arterial oxygen (PaO2) may underestimate hypoxia related to activities of daily living or sleep and thus not accurately reflect pulmonary hypertension (PH). The aim of the present study was to investigate the association of resting PaO2 with percent time of SpO2 below 90% (T90) and 88% (T88) in 24 hours. We also evaluated the capacity of hypoxia measures to predict PH in patients with idiopathic pulmonary fibrosis (IPF)...

INTRODUCTION: Right ventricular (RV) systolic dysfunction is common in acute respiratory distress syndrome (ARDS). While preload optimization is crucial in its management, dynamic fluid responsiveness indices lack reliability, and there is no consensus on target central venous pressure (CVP). We analyzed the utility of RV free wall longitudinal strain (RVFWS) in the estimation of optimal RV filling pressure in ARDS. METHODS: A retrospective cross-sectional analysis of clinical data and echocardiograms of patients with ARDS was performed...

Aortic stenosis (AS) leads to pulmonary hypertension (PH) and right ventricle (RV) failure. Our goal was to describe mortality related to postoperative complications in PH patients undergoing transcatheter aortic valve replacement (TAVR). Ninety-three TAVR patients were analyzed (controls, sPAP < 50 mmHg; cases, sPAP ≥ 50 mmHg). Significant findings in cases included increased mortality (365 days), post-TAVR atrioventricular block (AVB) and acute kidney injury (AKI), and increased mean length of stay (LOS)...
