Lung mechanics and exertional dyspnea in pulmonary arterial hypertension.
inspiratory capacity is often decreased in PAH, and that this is associated with a decreased aerobic exercise capacity and a shorter life expectancy. Inspiratory capacity is the difference between total lung capacity and functional residual capacity, and as such increases in the presence of expiratory airflow limitation or dynamic hyperinflation. The authors measured in 50 patients with PAH an ...
متن کاملExertional dyspnea and ventilation in hyperthyroidism.
Dyspnea is recognized to be an important feature in patients with hyperthyroidism at rest and during exercise. However, its etiology is not well-understood. Since dyspnea is thought to be related to the perception of excessive ventilatory effort, we explored the possibility that dyspnea in these patients might be related to an inappropriate ventilatory response to the increased metabolic rate. ...
متن کاملExertional dyspnea in mitochondrial myopathy: clinical features and physiological mechanisms.
Exertional dyspnea limits exercise in some mitochondrial myopathy (MM) patients, but the clinical features of this syndrome are poorly defined, and its underlying mechanism is unknown. We evaluated ventilation and arterial blood gases during cycle exercise and recovery in five MM patients with exertional dyspnea and genetically defined mitochondrial defects, and in four control subjects (C). Pa...
متن کاملQualitative aspects of exertional dyspnea in patients with interstitial lung disease.
We compared qualitative and quantitative aspects of perceived exertional dyspnea in patients with interstitial lung disease (ILD) and normal subjects and sought a physiological rationale for their differences. Twelve patients with ILD [forced vital capacity = 64 +/- 4 (SE) %predicted] and 12 age-matched normal subjects performed symptom-limited incremental cycle exercise tests with measurements...
متن کاملQualitative aspects of exertional dyspnea in patients with restrictive lung disease
Restrictive lung disease is a broad term encompassing a number of conditions in which lung volumes are reduced. Dyspnea is a common clinical manifestation of restrictive lung disease and frequently becomes a prominent and disabling symptom that undermines patients' ability to function and engage in activities of daily living (especially in those with more advanced restriction). Effective manage...
