Since blood flow impairment by aortic valve prosthesis is characteristically dynamic, this dynamic component is best and thoroughly appreciated by exercise Doppler echocardiography. We sought to determine the haemodynamics of a new pericardial aortic bioprosthesis (Trifecta™, St Jude Medical, MN, USA; T-AVB) at rest and during exercise and a 10-min ...

In heart failure (HF), the impaired left ventricular (LV) arterial coupling and diastolic dysfunction present at rest are exacerbated during exercise. We have previously shown that in HF at rest stimulation of β3-adrenergic receptors by endogenous catecholamine depresses LV contraction and relaxation. β3-Adrenergic receptors are activated at higher concentrations of ...

Cardiopulmonary function is reduced in adults born extremely preterm, but it is unknown if this results in reduced pulmonary gas exchange efficiency during exercise and, consequently, leads to reduced aerobic capacity in subjects with and without bronchopulmonary dysplasia (BPD). We hypothesized that an excessively large alveolar to arterial oxygen difference ...

Imagery rescripting (ImRS), i.e. changing intrusive mental images in imagery, is increasingly recognized as a helpful therapy technique. In ImRS exercises, patients sometimes suggest taking violent revenge on perpetrators. However, it is unclear whether vengeful phantasies can be particularly helpful in giving back feelings of power and control, or whether ...

The emerging role of exercise and especially exercise echocardiography in aortic stenosis has been recently emphasized. In this clinical setting, stress testing can help identify patients who are falsely asymptomatic, unmask those who will rapidly become symptomatic and appraise the true haemodynamic consequences of aortic stenosis. Both exercise stress test ...

In humans, β-adrenergic receptor activation causes a substantial portion of hypoxic vasodilation in skeletal muscle at rest and during forearm exercise. Recent evidence suggests that β-adrenergic receptors are either more sensitive or upregulated in young women vs. men. Therefore, we examined whether sex influences hypoxic vasodilation in 31 young subjects ...

Patients with chronic obstructive pulmonary disease (COPD) have reduced exercise tolerance associated with dyspnea. This exercise intolerance is primarily due to impaired ventilatory mechanics, but it is also associated with a combination of factors, including inefficient gas exchange, lactic acidosis at a low work rate, and exercise-induced hypoxemia. The survival ...

The development of muscle fatigue is oxygen (O2)-delivery sensitive [arterial O2 content (CaO2) × limb blood flow (QL)]. Locomotor exercise in acute hypoxia (AH) is, compared with sea level (SL), associated with reduced CaO2 and exaggerated inspiratory muscle work (Winsp), which impairs QL, both of which exacerbate fatigue individually by ...

Cognitive performances are tightly associated with the maximal aerobic exercise capacity (VO2max), both of which decline with age. The benefits on mental health of regular exercise, which slows the age-dependent decline in VO2max, have been established for centuries. In addition, the maintenance of an optimal cerebrovascular endothelial function through regular ...

Unilateral lesions to the medial forebrain bundle with 6-hydroxydopamine (6-OHDA) lead to force and timing deficits during a complex licking task. We hypothesized that training targeting tongue force generation during licking would improve timing and force measures and also lead to striatal dopamine sparing. Nine month-old male Fisher344/Brown Norway rats ...
