..The Pilates method has been increasingly applied for its therapeutic benefits, however little scientific evidence supports or rebukes its use as a treatment in patients with heart failure (HF)...

..23+/-1.82 to 10.53+/-1.97 m s(-1), P=ns). Continuous and interval exercise training were beneficial for blood pressure control, but only interval training reduced arterial stiffness in treated hypertensive subjects...

..We sought to evaluate the neurohormonal activity in heart transplant recipients and compare it with that in heart failure patients and healthy subjects during rest and just after a 6-minute walking test...

..Therefore, this review aims at integrating the knowledge on central and peripheral chemoreflexes in HF syndrome, as well as clarifying the influence of the heart failure drug therapy on the chemoreflexes...

..However, with the advent of betablockers in the treatment of HF, the prognostic values of peak VO2 and VE/VCO2 slope have not been fully established...

..Peak oxygen consumption and resting left ventricular ejection fraction (LVEF) are independent predictors of survival in adult heart failure (HF) patients. Aim: To evaluate these factors in children...

..However, little is known about the effects of PDE5 inhibition on 24-hour ambulatory pressure (ABP) and exercise blood pressure, noreprinephrine (Nor), and exercise capacity, especially after orthotopic heart transplantation (OHT)...

..The 6-minute walk test was suggested to be similar to that of daily activities. We investigated the effect of motivation during the 6-minute walk test in heart failure...

..To determine and compare the cardiopulmonary responses of healthy children and children with heart failure due to idiopathic dilated cardiomyopathy (IC) to progressive treadmill exercise testing...

..The aim of this study was to evaluate the reality of the treatment employed and its impact on the disease in patients followed at a specialized heart failure (HF) outpatient clinic...

..Greater abnormalities were observed in women with a strong family history of hypertension (FH++). These results suggest that there is an early vascular, metabolic and hormonal involvement in a familial hypertensive disorder...

..0, following the guideline recommendations. Standardizing the 6WT using the Borg scale was proposed to make sure that all patients undergo a submaximal walking test...

..Inhalation of nitric oxide attenuated the excessive increase in VT response to exercise in CHF. The L-arginine-nitric oxide pathway may be involved in mechanisms contributing to hyperventilation during exercise in CHF...

..The aim of our study was to evaluate the heart rate (HR), systolic and diastolic blood pressures in one session of strength exercises with and without neuromuscular electrostimulation (quadriceps) in HF patients and in healthy subjects...

..The object of this review is to discuss prescription and monitoring methods of physical exercise for CHF patients...

..However, it lacks specific information concerning breathlessness during daily activities...

..The aim of this study was to correlate CD34(+) levels to exercise capacity, functional class, quality of life and norepinephrine in heart failure patients...

..Calculating the maximum heart rate for age is one method to characterize the maximum effort of an individual. Although this method is commonly used, little is known about heart rate dynamics in optimized beta-blocked heart failure patients...

....

..The carvedilol's sympathetic blockade occurred during the rest and during the peak effort in the same proportion, but the exercise training's sympathetic blockade in healthy subjects occurred mainly in the rest...

..Despite being largely used within our context, the questionnaire had not yet been translated and validated into the Portuguese language...
