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...

Peripheral and respiratory muscles in chronic heart failure.

It is well-established that in patients with congestive heart failure (CHF), exercise is limited by fatigue and shortness of breath. The poor correlation between the fatigue and indices of central haemodynamic function might indicate that peripheral muscle alterations contribute to impaired exercise capacity. Intrinsic abnormalities of the skeletal muscles have been suggested as a possible expl...

Selenium deficiency was identified as a factor in the etiology of heart failure syndromes in areas of very low selenium intakes, such as China, where an endemic selenium-responsive cardiomyopathy is called Keshan disease.2 Similar cases of cardiomy...
