Respiratory muscle strength in chronic heart failure.
BACKGROUND Several studies have suggested that the respiratory muscles are weak in patients with heart failure, but the aetiology and clinical relevance of this weakness are unclear. In order to see if respiratory muscle weakness in this context is part of a more generalised myopathic process, respiratory and limb muscle strength were compared in patients with heart failure. The relation betwee...
متن کاملBreathing pattern, ventilatory drive and respiratory muscle strength in patients with chronic heart failure.
The purpose of this study was to evaluate whether chronic heart failure (CHF) may induce changes in breathing pattern and ventilatory neural drive. We studied 45 male inpatients with CHF, (25 patients in NYHA class II, 20 in class III) and 22 sex-matched post myocardial infarction patients without left ventricular dysfunction who served as controls. CHF patients underwent right heart catheteriz...
متن کاملRelation of respiratory muscle strength, cachexia and survival in severe chronic heart failure
BACKGROUND Respiratory muscle (RM) function predicts prognosis in non-cachectic patients with chronic heart failure (CHF). We hypothesized that weakness of RM (maximum inspiratory mouth occlusion pressure, Pimax) is a function of body mass index, and that outcome is more a function of BMI than of Pimax or ventilatory drive (P0.1). SUBJECTS AND METHODS We enrolled 249 CHF patients (11.2 % fema...
متن کاملthe relation of respiratory muscle strength to disease severity and abnormal ventilation during exercise in chronic heart failure patients
objectives the aim of this study was to investigate the relation between respiratory muscle strength and the severity of chf, and the influence of respiratory muscle strength on abnormal ventilation during exercise in chf patients. conclusions respiratory muscle strength is related to the severity of chf, and associated with rapid and shallow ventilation or excessive ventilation during exercise...
متن کاملRespiratory Muscle Dysfunction in Congestive Heart Failure
Background—In congestive heart failure (CHF), the prognostic significance of impaired respiratory muscle strength has not been established. Methods and Results—Maximal inspiratory pressure (Pimax) was prospectively determined in 244 consecutive patients (207 men) with CHF (ischemic, n575; idiopathic dilated cardiomyopathy, n5169; age, 54611 years; left ventricular ejection fraction [LVEF], 2261...
