Autor: A. Pazin-Filho, A.M.X. de Jesus, P.K.R. Magalhães, L.H. Melato, D. Campos, B.C. Maciel, L.M.Z. Maciel

Publikováno v: Brazilian Journal of Medical and Biological Research, Vol 42, Iss 8, Pp 744-749 (2009)

Amiodarone-induced thyroid dysfunction (AITD) is a common complication of amiodarone therapy and its prevalence varies according to iodine intake, subclinical thyroid disorders and the definition of AITD. There is no consensus about the frequency of

Autor: L.O. Murta Jr., E.E.S. Ruiz, A. Pazin-Filho, A. Schmidt, O.C. Almeida-Filho, M.V. Simões, J.A. Marin-Neto, B.C. Maciel

Publikováno v: Brazilian Journal of Medical and Biological Research, Vol 39, Iss 1, Pp 1-7 (2006)

The present study describes an auxiliary tool in the diagnosis of left ventricular (LV) segmental wall motion (WM) abnormalities based on color-coded echocardiographic WM images. An artificial neural network (ANN) was developed and validated for grad

Publikováno v: Brazilian Journal of Medical and Biological Research, Vol 35, Iss 6, Pp 741-752 (2002)

The purpose of the present study was to evaluate the effects of aerobic physical training (APT) on heart rate variability (HRV) and cardiorespiratory responses at peak condition and ventilatory anaerobic threshold. Ten young (Y: median = 21 years) an

Head-to-head comparison of dipyridamole, dobutamine and pacing stress echocardiography for the detection of myocardial ischemia in an animal model of coronary artery stenosis

Autor: A. Schmidt, O.C. de Almeida-Filho, E.M. Ayres-Neto, J.J. Carneiro, J.A. Marin-Neto, B.C. Maciel

Publikováno v: Brazilian Journal of Medical and Biological Research, Vol 34, Iss 7, Pp 903-911 (2001)

To compare the sensitivity of dipyridamole, dobutamine and pacing stress echocardiography for the detection of myocardial ischemia we produced a physiologically significant stenosis in the left circumflex artery of 14 open-chest dogs (range: 50 to 89

A pulsatile flow model for in vitro quantitative evaluation of prosthetic valve regurgitation

Autor: S. Giuliatti, L. Gallo Jr., O.C. Almeida-Filho, A. Schmidt, J.A. Marin-Neto, C.A. Pelá, B.C. Maciel

Publikováno v: Brazilian Journal of Medical and Biological Research, Vol 33, Iss 3, Pp 341-346 (2000)

A pulsatile pressure-flow model was developed for in vitro quantitative color Doppler flow mapping studies of valvular regurgitation. The flow through the system was generated by a piston which was driven by stepper motors controlled by a computer. T

Publikováno v: Brazilian Journal of Medical and Biological Research, Vol 31, Iss 5, p 705 (1998)

We investigated the effects of aerobic training on the efferent autonomic control of heart rate (HR) during dynamic exercise in middle-aged men, eight of whom underwent exercise training (T) while the other seven continued their sedentary (S) life st
