BACKGROUND: The change in the level of NT-Pro-BNP (N-terminal Pro-Brain Natriuretic Peptide) is now considered as a reflection of the hemodynamic alterations and its circulatory reductions reported early after successful PTMC (percutaneous transvenous mitral commissurotomy). The present study aims to assess the change in the level of NT-Pro BNP following PTMC in patients with mitral stenosis and also to determine the association between circulatory NT-Pro BNP reduction and post-PTMC echocardiography parameters...

The aim of the present study was to evaluate whether the baseline thiol/disulfide state can predict the occurrence of anthracycline induced cardiac toxicity. A total of 186 cancer patients receiving anthracycline (doxorubicin)-based chemotherapy were enrolled. All patients underwent 2-dimensional (2D) speckle tracking echocardiography (STE) to determine their left ventricular ejection fraction (LVEF) and blood samples for measuring thiol forms were obtained before treatment and 4 weeks after completion of the chemotherapy...

BACKGROUND: First-degree relatives of type-2 diabetes patients (FDR) present insulin resistance. We investigated whether FDR and dysglycaemic subjects demonstrate abnormal endothelial glycocalyx and LV deformation during postprandial hyperglycemia. METHODS: We studied 40 FDR with normal oral glucose test (OGTT), 40 subjects with abnormal OGTT (dysglycaemic) and 20 subjects with normal OGTT without parental history of diabetes (normoglycaemic). At 0 and 120min of OGTT we measured: a) LV longitudinal strain (LS) of subendocardial, mid-myocardial and subepicardial layers, global LS (GLS), peak twisting (pTw), untwisting velocity (pUtwVel), by speckle tracking echocardiography b) perfused boundary region (PBR) of the sublingual arterial microvessels; high PBR values represent reduced glycocalyx thickness...

BACKGROUND: Predicting which individuals will have a decline in left ventricular (LV) function after pacemaker implantation remains an important challenge. We investigated whether LV global longitudinal strain (GLS), measured by 2D speckle tracking strain echocardiography, can identify patients at risk of pacing-induced left ventricular dysfunction (PIVD) or pacing-induced cardiomyopathy (PICMP). METHODS: Fifty-five patients with atrioventricular block and preserved LV function underwent dual-chamber pacemaker implantation and were followed with serial transthoracic echocardiography for 12 months for the development of PIVD (defined as a reduction in LV ejection fraction (LVEF) ≥5 percentage points at 12 months) or PICMP (reduction in LVEF to <45%)...

BACKGROUND: Impairment of the adaptive mechanisms that increase cardiac output during exercise can translate to a reduced functional capacity. We investigated cardiovascular adaptation to exertion in asymptomatic hypertensive patients, aiming to identify the early signs of cardiac and vascular dysfunction. METHODS AND RESULTS: We enrolled 54 subjects: 30 patients (45.1±11.9years, 19 males) and 24 age-matched healthy controls (44.4±9.6years, 14 males). Speckle-tracking echocardiography (STE) and echo-tracking were performed at rest and during exertion to assess myocardial deformation and arterial stiffness...

INTRODUCTION: Ex vivo measurement of ascending aortic biomechanical properties may help understand the risk for rupture or dissection of dilated ascending aortas. A validated in vivo method that can predict aortic biomechanics does not exist. Speckle tracking transesophageal echocardiography (TEE) has been used to measure ventricular stiffness; we sought to determine whether speckle TEE could be adapted to estimate aortic stiffness in vivo and compare these findings with those obtained by ex vivo tissue measurements...

BACKGROUND: Fetal growth restriction (FGR) affects 5% to 10% of newborns and is associated with increased cardiovascular mortality in adulthood. We evaluated whether prenatal cardiovascular changes previously demonstrated in FGR persist into preadolescence. METHODS AND RESULTS: A cohort study of 58 FGR (defined as birth weight below 10th centile) and 94 normally grown fetuses identified in utero and followed-up into preadolescence (8-12 years of age) by echocardiography and 3-dimensional shape computational analysis...

The present study aimed to assess the mechanisms of effects of percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) from two different aspects: left ventricular (LV) systolic function assessed by two-dimensional speckle tracking echocardiography (2D-STE) and electrical stability evaluated by late potential on signal-averaged electrocardiogram (SAECG). We conducted a prospective observational study with consecutive CTO-PCI patients. 2D-STE and SAECG were performed before PCI, and after 1-day and 3-months of procedure...

BACKGROUND: In the early stages of atrial remodeling, aortic stiffness might be an indication of an atrial myopathy, in particular, atrial fibrosis. This study aimed to investigate the association between left atrial (LA) mechanical function, assessed by two-dimensional speckle tracking echocardiography, and aortic stiffness in middle-aged patients with the first episode of nonvalvular atrial fibrillation (AF). METHODS: This prospective study included 34 consecutive patients with the first episode of AF, who were admitted to Kartal Koşuyolu Research and Training Hospital between May 2013 and October 2015, and 31 age- and gender-matched healthy controls...

BACKGROUND: Identification of patients with latent rheumatic heart disease by echocardiography presents a unique opportunity to prevent disease progression. Myocardial strain is a more sensitive indicator of cardiac performance than traditional measures of systolic function. OBJECTIVE: The objective of this study was to test the hypothesis that abnormalities in myocardial strain may be present in children with latent rheumatic heart disease. METHODS: Standard echocardiography images with electrocardiogram gating were obtained from Ugandan children found to have latent rheumatic heart disease as well as control subjects...

BACKGROUND: Two-dimensional (2D) echocardiography is one of the most feasible, noninvasive methods for assessing the aortic diameter and biomechanical changes. We studied possible interfaces between noninvasive biomechanical and speckle-tracking (ST) echocardiographic data from dilated aortas. METHODS: Altogether, 44 patients with dilative pathology of ascending aorta (DPAA) were compared with subjects without ascending aortic dilation (diameter <40 mm). DPAA patients formed two groups based on diameter size: group 1, ≤45 mm diameter; group 2, >45 mm...

BACKGROUND: The CHA2 DS2 -VASc score is a classic predictor of stroke in patients with atrial fibrillation (AF). Decreased left atrial appendage flow velocity (LAA-FV) reflects the blood stasis, and left atrial (LA) strain is a manifestation of atrial remodeling. This study aimed to explore the effects of AF rhythm and CHA2 DS2 -VASc score in the development of thrombogenesis and their potential correlation with LAA-FV and LA strain. HYPOTHESIS: AF rhythm and high CHA2 DS2 -VASc score correlate independently with decreased LAA-FV, which can be predicted by LA strain...

Diastolic dysfunction is common in cardiac disease and an important finding independent of systolic function as it contributes to the signs and symptoms of heart failure. Tissue Doppler mitral early diastolic velocity (Ea) combined with peak transmitral early diastolic velocity (E) to obtain E/Ea ratio provides an estimate of the left ventricular (LV) filling pressure. However, E/Ea has a significant gray zone and less reliable in patients with preserved ejection fraction (>50%). Two-dimensional echocardiographic speckle tracking measure myocardial strain and strain rate (Sr) avoiding the Doppler-associated angulation errors and tethering artifacts...
