Incremental Prognostic Utility of Left Ventricular Global Longitudinal Strain in Hypertrophic Obstructive Cardiomyopathy Patients and Preserved Left Ventricular Ejection Fraction
BACKGROUND In obstructive hypertrophic cardiomyopathy patients with preserved left ventricular (LV) ejection fraction, we sought to determine whether LV global longitudinal strain (LV-GLS) provided incremental prognostic utility. METHODS AND RESULTS We studied 1019 patients with documented hypertrophic cardiomyopathy (mean age, 50±12 years; 63% men) evaluated at our center between 2001 and 20...
متن کاملGlobal Longitudinal Strain or Left Ventricular Twist and Torsion? Which Correlates Best with Ejection Fraction?
Background: Estimative of left ventricular ejection fraction (LVEF) is a major indication for echocardiography. Speckle tracking echocardiography (STE) allows analysis of LV contraction mechanics which includes global longitudinal strain (GLS) and twist/torsion, both the most widely used. Direct comparison of correlations between these novel parameters and LVEF has never been done before. Obj...
متن کاملassociation between androgenic hormone levels and left ventricular ejection fraction
background : androgens have been shown to have diverse effects on the cardiovascular system. the aim of this study was to compare androgenic hormone levels in patients with different left ventricular ejection fractions (ef). methods : the study population consisted of 515 consecutive men who were referred for angiographic studies and whose results of echocardiography and coronary angiography we...
متن کاملLeft Ventricular Volumes and Ejection Fraction
Left ventricular end-diastolic and end-systolic volume, stroke volume, and ejection fraction were determined by biplane angiocardiography and echocardiography in 27 patients suspected of having heart disease. Angiographic volumes were calculated by the area-length method and echocardiographic volumes, from the left ventricular dimension of the echograms. The angiographic minor diameter and the ...
متن کاملNormal Left Ventricular Ejection Fraction in Systemic
Ficuax 1. Two-dimensional echocardiogram stop frame images are shown above and accompanying schematics below. Left panel demonstrates an apical image with four heart chambers. Middle panel shows cloud of echoes from peripheral injection of normal saline solution demonstrating simultaneous appearance of echoes in all four chambers. A similar injection postoperatively demonstrates echoes in right...
