Lung function and exercise gas exchange in chronic heart failure.
BACKGROUND The ventilatory response to exercise in patients with chronic heart failure (HF) is greater than normal for a given metabolic rate. The objective of the present study was to determine theExpand

Medium-term effectiveness of L-thyroxine treatment in idiopathic dilated cardiomyopathy.
BACKGROUND In dilated cardiomyopathy, short-term administration of L-thyroxine (100 micrograms/ day) improves cardiac and exercise performance without changing the heart's adrenergic sensitivity. TheExpand

Afterload reduction: a comparison of captopril and nifedipine in dilated cardiomyopathy.
Nifedipine and captopril are potent vasodilators and may be expected to help left ventricular failure by reducing afterload. Nifedipine (20 mg three times a day) and captopril (50 mg three times aExpand

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

Contribution of PO2, P50, and Hb to changes in arteriovenous O2 content during exercise in heart failure.
Arteriovenous O2 content (a-vCO2) differences increase during exercise in normal subjects through several mechanisms including PO2, O2 pressure at which hemoglobin (Hb) is half saturated with O2Expand

Statement on cardiopulmonary exercise testing in chronic heart failure due to left ventricular dysfunction: recommendations for performance and interpretation Part I: Definition of cardiopulmonary
Cardiopulmonary exercise testing (CPET) provides a global assessment of the integrated response to exercise involving the pulmonary, cardiovascular, haematopoietic, neuropsychological, and skeletalExpand

A four-minute submaximal constant work rate exercise test to assess cardiovascular functional class in chronic heart failure.
To develop a submaximal constant work rate exercise test able to grade cardiovascular dysfunction in patients with chronic heart failure, 80 patients and 59 control subjects performed aExpand

The discriminatory value of the P(A-a)O2 during exercise in the detection of asbestosis in asbestos exposed workers.
Asbestosis is commonly associated with abnormalities of gas transport but since most asbestos workers are smokers and smokers also commonly have abnormalities in P(A-a)O2, the actual specificity andExpand
