Application of fMRI to clinical neurology implies the selection of a simple task and control of the task performance. The capability to objectively monitor variables related to task execution is, therefore, important and could improve accuracy of clinical fMRI studies. We assessed the influence of different self-paced frequencies of a simple motor task on(More)
We studied 10 adult patients with active acromegaly (4 men and 6 women, mean age 55 +/- 5 years and mean body mass index 27.9 +/- 1.1 kg/m2). Control values for the echocardiographic and exercise studies were obtained from 10 normal subjects matched for sex and age (5 men and 5 women, age 51.1 +/- 3.7 years and body mass index 25.3 +/- 1 kg/m2). Each(More)
BACKGROUND A study was undertaken to investigate whether bronchodilators are associated with less breathlessness at rest and during light exercise in patients with moderate to severe chronic obstructive pulmonary disease (COPD) with resting tidal expiratory flow limitation (EFL; flow limited (FL)) compared with those without EFL (non-flow limited (NFL)). (More)
BACKGROUND In patients with acute left heart failure (LHF), orthopnea has also been related to the occurrence or worsening of expiratory flow limitation (EFL) in the supine position. We wished to assess whether short-term treatment with vasodilators and diuretics was able to abolish supine EFL and whether this could help to control orthopnea in patients(More)
We have previously shown that transdermal nitroglycerin may induce an increase in the activity of the adrenergic and the renin-angiotensin-aldosterone systems (SRAA) in patients with chronic stable angina pectoris (SA); when the activation of these systems is more pronounced, the antianginal effect of this drug seems to be reduced. The aim of this study was(More)
BACKGROUND Lower peak expiratory flow (PEF) and forced expiratory volume in 1 s (FEV(1)) have been consistently found after slow inspiration with end-inspiratory pause (EIP). OBJECTIVES It was the aim of this study to establish the respective influence of the speed of preceding inspiration (SPI) and EIP on the parameters obtained from the following(More)
To evaluate the effects of supervised exercise training (SET) on cardiometabolic risk, cardiorespiratory fitness and oxidative stress status in 2 diabetes mellitus (T2DM), twenty male subjects with T2DM were randomly assigned to an intervention group, which performed SET in a hospital-based setting, and to a control group. SET consisted of a 12-month(More)
In order to evaluate the possible role played by snoring as a risk factor for cardiovascular disease, we studied 400 patients aged 30-80 years, divided into 4 groups matched for age, sex and body mass index. The first group consisted of 100 patients who snored, having risk factors (hypertension, diabetes, obesity, smoking, high serum cholesterol level) for(More)
Aortic rigidity, plasma noradrenaline and adrenaline, and hemodynamic parameters were measured in 48 essential hypertensive patients, 25 younger than 45 (Group I) and 23 of 45 years and over (Group II). Aortic rigidity was determined by the ratio of pulse pressure over stroke volume. Aortic rigidity and hemodynamic parameters were also determined after(More)
Captopril 25 mg every 8 hours for 1 month appeared to improve dynamic effort tolerance and cardiac function under the stress of isometric exercise in patients with chronic heart failure, functional class II-III NYHA. The improvement was comparable to that obtained in the same subjects with digoxin 0.25 mg once a day given for a similar period of 1 month.(More)
