background: echocardiographic evaluations of the longitudinal axis of the left ventricular (lv) function have been used in the diagnosis and assessment of heart failure with normal ejection fraction (hfnef). the evaluation of the global and segmental peak systolic longitudinal strains (pslss) by two-dimensional speckle tracking echocardiography (ste) may correlate with conventional echocardiogr...

To determine the prevalence and correlates of left ventricular systolic dysfunction in hypertensive patients in a biracial population-based sample, clinical evaluation and echocardiography were performed in 2086 participants in the Hypertension Genetic Epidemiology Network (HyperGEN) examination; 86% had normal ejection fraction (.54%), 10% had mild ventricular dysfunction (ejection fraction 41...

Left ventricular and left atrial volume, left ventricular ejection fraction, and left ventricular muscle mass were determined preoperatively and postoperatively in 13 patients who underwent surgical closure of ventricular septal defects in the first two years of life. Left ventricular end-diastolic volume and systolic output averaged 255 ± 19% (± SEM) and 240 ± 19% of normal, respectively, befo...

abstract background prevention of myocardial siderosis is a key step to reduce rate of mortality in thalassemic patients. our objective was to study association between echocardiography parameters and serum ferritin level in patients with major thalassemia. materials and methods sixty-six patients with major thalassemia were studied in amir kabir hospital, arak, iran. serum ferritin levels were...

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...

The relationship between ambulatory intra-arterial blood pressure and left ventricular ejection fraction was examined in a group of 23 untreated hypertensive subjects who underwent concurrent radionuclide ventriculography. All patients had a normal ejection fraction at rest (range, 50-80%), and no significant correlation was found between blood pressure and resting ejection fraction. Sixty-one ...

OBJECTIVE To examine cardiopulmonary values, static lung function, and ejection fraction in adult patients with congenitally corrected transposition of the great arteries (CCTGA). PATIENTS AND METHODS 41 patients who had undergone static lung function testing and cardiopulmonary exercise tests with measurements of ejection fraction were identified at the Toronto Congenital Cardiac Centre for ...

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 ...
