AIM The aim of this study was to detect abnormalities in left ventricular myocardial function due to HIV (human immunodeficiency virus) infection without established cardiovascular disease. METHODS An echocardiogram was performed in 50 asymptomatic HIV-infected patients (age 41 ± 6 years, 64% male) and in 20 healthy individuals. Conventional echocardiography and pulsed tissue Doppler imaging ...

conclusions according to our multimodality imaging approach, hypertrophic cardiomyopathy was the most probable diagnosis. case presentation we describe a 73-year-old woman referred to us for consultation because of a giant negative t wave on her electrocardiography. echocardiography revealed diffuse severe hypertrophy associated with hypertrophied anterolateral papillary muscles with a bifid he...

background obstructive sleep apnea (osa) is a common sleep disease. it is associated not only with hypertension but also with other cardiac complications. thus, the early detection of cardiac disorders is very useful. objectives we sought to evaluate different echocardiographic parameters. patients and methods this cross-sectional study was done on 55 patients with osa. the patients were divide...

BACKGROUND Evaluation of myocardial function by speckle-tracking echocardiography is a new method for the early diagnosis of systolic dysfunction. OBJECTIVES We aimed to determine myocardial speckle-tracking echocardiography indices in Kawasaki Disease (KD) patients and compare them with the same indices in control subjects. PATIENTS AND METHODS Thirty-two patients (65.5% males) with KD and...

Case summary A 5-month-old intact female Scottish Fold cat was presented for cardiac evaluation. Careful auscultation detected a slight systolic murmur (Levine I/VI). The findings of electrocardiography, thoracic radiography, non-invasive blood pressure measurements and conventional echocardiographic studies were unremarkable. However, two-dimensional speckle tracking echocardiography revealed ...

OBJECTIVES The pixel velocity values obtained by color Doppler tissue imaging (DTI) can be processed to velocity gradients as a measure of longitudinal strain rate with a technique termed strain rate imaging (SRI). Color mapping of strain rate does show the spatial-temporal relations of the diastolic phases. The phases of early filling and late filling during atrial systole can be seen to consi...

Under plane stress conditions, most micromechanical and phenomenological models predict a minimum in ductility for strain tension state. Therefore, the state of plays crucial role many forming crash applications reliable measurement to fracture is particularly when calibrating modern initiation models. Recently, new experimental technique has been proposed measuring sheet metal after proportion...

background: heat stress is a common and usual problem in industries. several indices, including wet bulb globe temperature (wbgt), are used to evaluate heat stress. however, wbgt index has limitations such as high cost and response time. it is not thus suitable as a screening tool. heat strain scoring index (hssi) is also an observational-judgmental technique that has been developed for primary...

Background: Left ventricular longitudinal strain (LV-LS) and strain rate (SR) are sensitive markers of early systolic dysfunction. Aim: To evaluate the feasibility of a novel, cardiac magnetic resonance (CMR) based method known as feature tracking (FT) for the assessment of strain and SR, and to compare the CMR based results to those obtained on standard transthoracic echocardiography (TTE) in ...
