Cardiopulmonary exercise testing in differential diagnosis of dyspnea.
Dyspnea is a common exercise-induced symptom whose treatment is often improperly because the pathophysiology causing the exercise intolerance is not well understood. The most important requirement for exercise performance is transport of oxygen to support the bioenergetic processes in the muscle cells (including, of course, the heart) and elimination of the carbon dioxide formed as a product of...
متن کاملExertional dyspnoea in COPD: the clinical utility of cardiopulmonary exercise testing.
Activity-related dyspnoea is often the most distressing symptom experienced by patients with chronic obstructive pulmonary disease (COPD) and can persist despite comprehensive medical management. It is now clear that dyspnoea during physical activity occurs across the spectrum of disease severity, even in those with mild airway obstruction. Our understanding of the nature and source of dyspnoea...
متن کاملExertional dyspnoea in interstitial lung diseases: the clinical utility of cardiopulmonary exercise testing.
Interstitial lung diseases (ILDs) represent a heterogeneous group of pathologies characterised by alveolar and interstitial damage, pulmonary inflammation (usually associated with fibrosis), decreased lung function and impaired gas exchange, which can be attributed to either a known or an unknown aetiology. Dyspnoea is one of the most common and disabling symptoms in patients with ILD, signific...
متن کاملDyspnea in a patient years after severe poliomyelitis. The role of cardiopulmonary exercise testing.
Dyspnea after polio can occur for a variety of reasons, including neuromuscular disease and upper airway abnormalities resulting from prolonged intubation, including tracheal stenosis, tracheomalacia, and vocal cord paralysis. Routine studies such as spirometry and maximum voluntary ventilation (MVV) measurements can give similar results in these conditions. We present a 50-year-old woman who a...
متن کاملCardiopulmonary exercise testing: how do we differentiate the cause of dyspnea?
Case report: A 54-year-old man is referred for dyspnea on exertion. He has a history of type II diabetes and 35 pack-years of smoking. He suffered an anterior myocardial infarction 14 months ago, and on recent echocardiography was found to have an ejection fraction of 25%. Since his myocardial infarction, he has quit smoking and has gained an additional 27 pounds. He admits to a sedentary lifes...
