  • Opredelitev učinka hemodialize z doplersko ehokardiografsko analizo hitrosti mitralnega in pulmonalnega venskega pretoka = Effects of hemodialysis on left ventricular diastolic filling: transthoracic Doppler echocardiographic analysis of mitral and pulmonary venous flow velocity patterns
    Markež, Jernej ...
    Background. Pulsed Doppler echocardiography (PDE) was used to evaluate the velocity and other filling parameters of left atrium (LA) and left ventricle (LV), enabling us to estimate the diastolic ... function of LV. The velocity curves are influenced not only by the diastolic properties of LV (relaxation, compliance) but also by the preload. Hemodialysis (HD) causes acute decrease of intravascular volume and the preload. The aim of this study was to determine the effect of HD on PDE variables of the transmitral and pulmonary vein flow. Methods. The study group consisted of 27 patients on maintenance HD(17 women and 10 men; aged 22 to 73 years, mean 54+-14 years). The inclusioncriteria were: sinus rhythm, heart rate 50 do 90 beats/min., normal LV systolic function (shortening fraction - 5 FS above 30%), absence of history of myocardial infarction, no significant valvular disease, adequate transthoracic recordings of pulmonary venous flow velocity. The duration of HDtreatment was 1 to 13 years, on average 5.7 years. Patients were examined immediately before and after the same standrd bicorbonate HD. Patients underwent clinical examination, M-mode, two-dimensional and Doppler echocardiography. Results. 18 pats (67%) had LV hypertrophy (LV mass index after HD: 141.3+-54.0 g/m2). After HD the body weight was decreased from 61.2+-9,1 kg to 59.3+-9 kg (p < 0.05). Heart rate and blood pressure did not changes significantly during HD. Diastolic diameter of LV was decreased from 53.7+-to 50.4+-6.6 mm (p < 0.001),% FS was not changes. (Abstract truncated at2000 characters)
