Abstract Background Exercise capacity is usually reduced in Fontan patients, however there a subset of patients who have normal exercise and better outcomes, the “Super-Fontans”. The aim this study was to characterize cohort undergoing cardiopulmonary testing (CPET) identify predictors functional capacity. Methods Single center retrospective analysis consecutive aged >10 years old underw...

Angus crossbred steers (n = 40; 563 ± 44 kg) were used to examine the effects of handling method and fat thickness on the blood chemistry and physiology of market steers. Steers were blocked by backfat (BF) thickness and were randomly assigned to treatment groups: low-stress handling (LSH) and aggressive handling (AH). Cattle were then ran¬domly assigned to one of 5 blocks containing 4 steers f...

BACKGROUND The clinical significance of acute vasoreactivity testing (AVT) in patients with chronic thromboembolic pulmonary hypertension (CTEPH) remains unclear. We analyzed changes in hemodynamics and oxygenation dynamics indices after AVT in patients with CTEPH using patients with pulmonary arterial hypertension (PAH) as controls. METHODS We analyzed retrospectively the results of AVT in 8...

The purpose of this study was to evaluate the limiting factors of maximal aerobic performance in endurance trained (TW) and sedentary (UW) women. Subjects performed four incremental tests on a cycle ergometer at sea level and in normobaric hypoxia corresponding to 1000, 2500 and 4500 m. Maximal oxygen uptake decrement (Delta VO2 max) was larger in TW at each altitude. Maximal heart rate and ven...

AIM The aim of the study was to compare the effects of conventional exercise (CE), swimming and walking on the pulmonary functions, aerobic capacity, quality of life, Bath indexes and psychological symptoms in patients with ankylosing spondylitis (AS). METHODS Forty-five patients were randomised into either swimming (group 1), walking (group 2), CE group (group 3). Patients in Group 1 perform...

BACKGROUND The relationship of the genotype for the angiotensin-converting enzyme (ACE) with exercise capacity or training effects has been studied in athletes or healthy persons, but recently the ACE DD genotype was reported to be associated with decreased exercise capacity in patients with congestive heart failure. Therefore, in the present study the association between the ACE genotype and e...

AIM Determination of the importance of exercise tissue Doppler echocardiography in prognostic stratification of congestive heart failure patients with systolic dysfunction. METHODS 106 patients with congestive heart failure and LVEF ≤ 45% on optimal pharmacotherapy were included in the study. Results of resting and post-exercise echocardiography, cardiopulmonary exercise test and serum BNP le...

Radiometer Blood Micro-system 2 was used in studies designed to, (a) compare the mean blood gas and acid-base values of 38 normal horses and 20 horses with chronic obstructive pulmonary disease (COPD), (b) determine the means and standard deviations of blood gas and acid-base values of Thoroughbred horses in training, and (c) investigate the relationships between clinical data, blood gas values...

Hemodynamic and oxygen transport effects of dopamine and dobutamine were studied in a series of 25 critically ill postoperative general surgical patients by a prospective, randomized crossover design after maximal response to fluids had been obtained. Dopamine increased MAP, HR, CI, PvO2, DO2, and Qsp while decreasing PaO2. Dobutamine increased HR, CI, SI, stroke work, DO2, VO2, and Qsp while d...

The aim of this study was to evaluate the 24-hour ambulatory blood pressure monitoring (ABPM) response to exercise training (ET) in heart failure (HF) patients. Twelve HF patients and 15 sedentary healthy controls underwent ET for 2 months (3 times per week from 80%-90% of the ventilatory threshold). ABPM was performed before and 2 days after the last exercise season. Despite the fact that ET i...
