RT Journal Article SR Electronic T1 Exertional dyspnoea in chronic heart failure: the role of the lung and respiratory mechanical factors JF European Respiratory Review JO EUROPEAN RESPIRATORY REVIEW FD European Respiratory Society SP 317 OP 332 DO 10.1183/16000617.0048-2016 VO 25 IS 141 A1 Bruno-Pierre Dubé A1 Piergiuseppe Agostoni A1 Pierantonio Laveneziana YR 2016 UL http://err.ersjournals.com/content/25/141/317.abstract AB Exertional dyspnoea is among the dominant symptoms in patients with chronic heart failure and progresses relentlessly as the disease advances, leading to reduced ability to function and engage in activities of daily living. Effective management of this disabling symptom awaits a better understanding of its underlying physiology.Cardiovascular factors are believed to play a major role in dyspnoea in heart failure patients. However, despite pharmacological interventions, such as vasodilators or inotropes that improve central haemodynamics, patients with heart failure still complain of exertional dyspnoea. Clearly, dyspnoea is not determined by cardiac factors alone, but likely depends on complex, integrated cardio-pulmonary interactions.A growing body of evidence suggests that excessively increased ventilatory demand and abnormal “restrictive” constraints on tidal volume expansion with development of critical mechanical limitation of ventilation, contribute to exertional dyspnoea in heart failure. This article will offer new insights into the pathophysiological mechanisms of exertional dyspnoea in patients with chronic heart failure by exploring the potential role of the various constituents of the physiological response to exercise and particularly the role of abnormal ventilatory and respiratory mechanics responses to exercise in the perception of dyspnoea in patients with heart failure.In heart failure, respiratory and peripheral factors play a significant role in exertional dyspnoea development http://ow.ly/8oEN301w55l
