background: the aim of this study was to echocardiographically assess the effects of eecp (enhanced external counterpulsation therapy) therapy on systolic and diastolic cardiac function. methods: lvef (left ventricular ejection fraction), esv (end-systolic volume), edv (end-diastolic volume), sm (myocardial systolic wave) , ea (myocardial early diastolic wave), vp (propagation velocity), e/ea (...

BACKGROUND AND PURPOSE Transcranial color-coded real-time sonography (TCCS) is a useful tool to evaluate disease of the middle cerebral artery (MCA). This study was undertaken to identify TCCS criteria for the diagnosis of MCA stem and MCA branch occlusions. METHODS TCCS and digital subtraction angiography were performed in 55 consecutive patients with acute stroke: 10 with MCA stem occlusion...

Objectives: The purpose of this study was to assess how the preload reduction a#ects left ventricular LV diastolic function in hemodialysis patients with LV hypertrophy. Methods: Subjects included 14 patients with LV hypertrophy receiving hemodialysis. The subjects underwent echocardiographic and pulsed Doppler examinations before and after hemodialysis, and the data were analyzed to determine ...

Background: Considering the association between cardiac abnormalities and non-alcoholic fatty liver disease (NAFLD), the present study aimed to evaluate the relationship between biopsy-proven NAFLD and functional echocardiographic parameters, including left ventricular (LV) global longitudinal strain (GLS) in asymptomatic individuals. Methods: Thirty asymptomatic patients with liver biopsy-prov...

BACKGROUND AND PURPOSE It is unknown how little flow velocity improvement is necessary to achieve recanalization and clinical recovery. We sought to investigate which flow velocity parameter was associated with complete recanalization/reperfusion and neurological improvement in patients receiving reperfusion therapies. METHODS Patients with proximal intracranial occlusions were treated with s...

The normal human left ventricular response to large variations in preload was studied in 12 young men. M-mode echocardiograms were recorded at supine rest and compared with studies obtained during head-down tilt (HDT) at 50 and during progressive lower body negative pressure (LBNP) to -40 mm Hg. During HDT, end-diastolic volume (EDV) increased 23% (p < 0.001), stroke volume (SV) increased 35% (...

doppler ultrasound can provide important information about vascular problems through the analysis of blood flow wave-form. the purpose of this study was obtaining the normal images of color doppler and estimation of blood flow velocity parameters of femoral artery in rabbits. left and right femoral arteries of 8 healthy adult new zealand rabbits were evaluated. color and spectral doppler images...

AIM To investigate the relation between blood flow parameters of the retrobulbar vessels measured by means of colour Doppler imaging (CDI) and fluorescein filling defects of the optic nerve head in patients with normal tension glaucoma (NTG) and control subjects. METHODS 29 patients with NTG and 29 age and sex matched control subjects were included in this study. Blood flow velocities-peak sy...

INTRODUCTION The aim of the work is to evaluate the effect of repeated intracavernosal self-injection of vasoactive drugs in patients with elevated End Diastolic Velocity (>5 cm/sec) during pharmacopenile duplex ultrasonography (PPDU). METHODS Duplex evaluation was performed to the patients on self-injection therapy for comparison of end diastolic velocity and resistive index before and after...
