An echocardiographic study helps in the assessment of systolic and diastolic left ventricular function due to potential clinical implications over the treatment and the prognosis of different heart diseases. Systolic function depends on three factors: the left ventricular (LV) function, arterial coupling (ventriculoarterial coupling) and blood volume. In the particular case of the left ventricu...

BACKGROUND Our aim was to determine whether regional left ventricular (LV) function on a resting transthoracic echo (TTE) provides prognostic information in patients with varying degrees of ischemia on myocardial perfusion imaging. METHODS Between 2004 - 2009, we identified 503 patients (mean age 69 (SD 11); 79% male) with reversible ischemia on a myocardial SPECT scan who had a TTE within 30...

background: severe and prolonged physical training is associated with morphological and physiological cardiac changes, often termed as the “athlete’s heart”. echocardiographic features peculiar to elite iranian athletes have not been previously described. the aim was to examine the echocardiographic characteristics of highly trained iranian athletes involved in three different sports.   methods...

OBJECTIVE In patients with aortic stenosis (AS), the left ventricular (LV) geometry changes due to the increased LV afterload. However, subclinical myocardial dysfunction can develop despite a normal LV ejection fraction (EF). This study was an investigation of subclinical LV systolic dysfunction in patients with severe AS with a normal LV EF using a strain imaging method, speckle-tracking echo...

Obesity is an increasingly prevalent cardiovascular risk factor. It implies a hemodynamic overload, leading to functional anatomical changes in the heart, with ventricular hypertrophy and systo-diastolic dysfunction. The most effective treatment is bariatric surgery, which has a cardioprotective effect, improving ventricular geometry and function. We analyzed medium-term structural and function...

Background It is emerging that distribution of body fat, and in particular visceral fat (VFAT) is more important in determining cardiovascular risk than total body fat percentage. Rouxen-Y gastric bypass (RYGB) may preferentially reduce visceral fat, thus providing a mechanism to study the impact of visceral fat on cardiovascular function. We sought to determine 1) whether visceral fat is relat...

introduction left ventricular (lv) twist is believed to store potential energy and plays an important role in generating diastolic suction. recent advances in echocardiography techniques have allowed quantification of lv twist. the aim of the present study was to compare lv twist and torsion in healthy human subjects determined by velocity vector imaging (vvi) and tissue doppler imaging (tdi) a...

Aim . To analyze clinical and paraclinical data in patients with documented cardiac sarcoidosis, outlining the key points of diagnosis selection optimal treatment. Material methods For period from 2016 to 2021, 63 (50,4±14,1 years) were included cohort study on negotiability. Based a standard examination, 15 (41±13 years old) selected, who continued examination confirm sarcoidosis. Contrast-enh...

Thirteen patients who had ventricular septal defects (VSDs) after myocardial infarction (MI) underwent two-dimensional echocardiography (2-D echo), with confirmation of the VSD by oximetry. Eight of the patients were male and five were female, ages 51-76 years. Five had anterior and eight inferior MIs. Two-dimensional echocardiography revealed akinesis or dyskinesis of the interventricular sept...
