With the introduction of high-sensitivity troponin (hsTNI) assays, the clinical significance unstable angina (UA) has become uncertain. We hypothesized that impaired left ventricular (LV) two-dimensional speckle-tracking echocardiography (2D-STE)-derived peak global longitudinal strain (GLS) was able to exclude the presence of significant coronary artery disease (CAD) in UA patients without prior cardiovascular (CV) events and with a normal LV ejection fraction (LVEF). From a cohort of 200 patients admitted with UA, we selected 61 patients without prior CV events and with a normal LVEF; of these, 48 (79%) underwent invasive coronary angiography (ICA) and 24 (39%) had at least ≥ 1 significant stenosis...

BACKGROUND: Genital dissatisfaction is an important reason for transmen to undergo genital gender-confirming surgery (GCS; phalloplasty or metoidioplasty). However, little is known about motives for choosing specific techniques, how transmen benefit postoperatively, and whether psychosexual outcomes improve. AIM: To evaluate motivations for and psychosexual outcomes after GCS. METHODS: A longitudinal study of 21 transmen at least 1 year after GCS was conducted...

BACKGROUND: Coexistence of left ventricular (LV) longitudinal myocardial systolic dysfunction with LV diastolic dysfunction could lead to heart failure with preserved ejection fraction (HFpEF). Diabetes mellitus (DM) is known as a significant factor associated with HFpEF. Although the mechanisms of DM-related LV myocardial injury are complex, it has been postulated that overweight contributes to the development of LV myocardial injury in type 2 diabetes mellitus (T2DM) patients. However, the precise impact of overweight on LV longitudinal myocardial systolic function in T2DM patients remains unclear...

BACKGROUND: Interstitial fibrosis, myocardial fiber disarray and non-uniform shortening are common histological features of hypertrophic cardiomyopathy (HCM). The degree of LV hypertrophy and fibrosis are postulated to contribute to the impairment of myocardial shortening. Cardiovascular magnetic resonance myocardial (CMR) feature tracking (CMR-FT) has emerged as a robust method that provides quantitative measurements of myocardial deformation. Our aim was first to evaluate LV strain parameters in HCM by CMR-FT and their dependence on both functional parameters and late gadolinium enhancement (LGE); and secondly we sought to determine their association with major cardiovascular outcomes...

Background: Arterial stiffness increases pressure load to the left ventricle (LV), leading to LV hypertrophy and subendocardial ischemia. Neurohormones stimulate myocardial fibrosis and LV dysfunction. We aimed to explore the associations of arterial stiffness and plasma aldosterone with multi-directional, layer-specific LV, and left atrial (LA) mechanical function in hypertensive patients. Methods: Layer-specific LV global longitudinal strain (GLS-trans, GLS-endo, GLS-epi), global circumferential strain (GCS-trans, GCS-endo, GCS-epi), LV torsional parameters, and LA global longitudinal strain (LA GLS) were analyzed by two-dimensional speckle tracking echocardiography in 195 hypertensive patients (110 men, mean age 55 years)...

BACKGROUND: Peak systolic global longitudinal strain (GLS) is increasingly used to quantify left ventricular systolic function. The primary objective of this study was to assess whether GLS obtained during intraoperative transesophageal echocardiogram, performed before cardiopulmonary bypass, improves the prediction of postoperative low cardiac output syndrome (LCOS) after adult cardiac surgery. METHODS: GLS from 275 patients undergoing on-pump cardiac surgery was calculated retrospectively using two-dimensional- speckle tracking echocardiography (aCMQ module from Qlab software version 10...

BACKGROUND: Chronic hypertension (cHTN) affects 7% of all pregnancies. We hypothesized that cHTN during pregnancy would be associated with abnormal myocardial strain patterns and adverse perinatal outcomes. METHODS: This was a retrospective cohort study of patients seen in a high-risk obstetrics clinic with cHTN. Parturients with a singleton pregnancy who had undergone an echocardiogram as part of routine clinical care were eligible. Clinical and demographic information was collected from medical records...

BACKGROUND: Autologous hematopoietic cell transplantation (HCT) is a first-line therapy for prolonging survival in patients with light-chain (AL) amyloidosis. Cardiac involvement is the most important determinant of survival. However, patients with advanced cardiac involvement have often been excluded from HCT because of high risk for transplantation-related mortality and poor overall survival. Whether baseline left ventricular global longitudinal strain (GLS) can provide additional risk stratification and predict survival after HCT in this high-risk population remains unclear...

INTRODUCTION: Pre-eclampsia is associated with many cardiovascular disorders present even in asymptomatic women. Several echocardiographic parameters are used to identify them. However, these parameters may be normal until late in the course of the disease process. Which justifies using new and more sensitive techniques. PURPOSE: We sought to test the hypothesis of subclinical cardiac involvement in such patients, based on speckle tracking, and to check its sensitivity compared to the usual methods...

Glutamine catabolism is considered to be an important metabolic pathway for cancer cells. Glutaminase (GLS) is the important rate-limiting enzyme of glutamine catabolism. miR-137 functions as a tumor suppressor in many human malignant tumors. However, the role and molecular mechanism of miR-137 and GLS in malignant melanoma has not been reported. In this study, we showed that miR-137 was decreased in melanoma tissue, and the low miR-137 level and high GLS expression are independent risk factor in melanoma. miR-137 suppressed the proliferation and glutamine catabolism of melanoma cells...

BACKGROUND: Twenty-four-hour Blood Pressure (BP) variability is an important predictor of organ damage and cardiovascular events. Although epidemiological data are widely based on evaluation of office (Clinic) BP, 24-hour Ambulatory BP monitoring (ABPM) accurately assess the severity of hypertension to predict cardiovascular events in hypertensive patients, because it more accurately reflects BP load on heart and blood vessels. Conventional transthoracic echocardiography (TTE), such as M-mode and two-dimensional (2D), and more advanced techniques, such as tissue Doppler imaging (TDI) and speckle tracking echocardiography (STE), are used to identify pathological changes of the hypertensive heart disease...

Remote ischemic conditioning (RIC) protects against acute ischemia-reperfusion injury and may also have beneficial effects in patients with stable cardiovascular disease. We investigated the effect of long-term RIC treatment in patients with chronic ischaemic heart failure (CIHF). In a parallel group study, 22 patients with compensated CIHF and 21 matched control subjects without heart failure or ischemic heart disease were evaluated by cardiac magnetic resonance imaging, cardiopulmonary exercise testing, skeletal muscle function testing, blood pressure measurement and blood sampling before and after 28 ± 4 days of once daily RIC treatment...

BACKGROUND: Gravity affects every aspect of cardiac performance. When gravitational gradients are at their greatest on Earth (i.e., during upright posture), orthostatic intolerance may ensue and is a common clinical problem that appears to be exacerbated by the adaptation to spaceflight. We sought to elucidate the alterations in cardiac performance during preload reduction with progressive upright tilt that are relevant both for space exploration and the upright posture, particularly the preload dependence of various parameters of cardiovascular performance...
