Usefulness of L-thyroxine to improve cardiac and exercise performance in idiopathic dilated cardiomyopathy.
The short-term effects of L-thyroxine (100 micrograms/day, 10 patients) and placebo (10 patients) on idiopathic dilated cardiomyopathy were compared. Before and at the end of the treatment, aExpand

[Changes in pulmonary vascular reactivity to adrenergic stimuli in congestive heart failure].
Heart failure is associated with increased activity of sympathetic nervous system. As to the latter's effector organs, attention has been mainly drawn by heart and systemic circulation. In this studyExpand
[The improvement in physical exercise capacity in dilated cardiomyopathy during short-term treatment with L-thyroxine].
Reduced left ventricular function and other factors, such as vascular resistances, redistribution of cardiac output and impaired muscular metabolism, limit exercise performance in chronic heartExpand
