A randomized double-blind trial of enalapril in older patients with heart failure and preserved ejection fraction: effects on exercise tolerance and arterial distensibility.
BACKGROUND Exercise intolerance is the primary symptom in older patients with heart failure and preserved ejection fraction (HFPEF); however, little is known regarding its mechanisms and therapy. METHODS AND RESULTS Seventy-one stable elderly (70+/-1 years) patients (80% women) with compensated HFPEF and controlled blood pressure were randomized into a 12-month follow-up double-blind trial of...
متن کاملEffects of the Novel Long-Acting GLP-1 Agonist, Albiglutide, on Cardiac Function, Cardiac Metabolism, and Exercise Capacity in Patients With Chronic Heart Failure and Reduced Ejection Fraction.
OBJECTIVES This study sought to determine if glucagon-like peptide (GLP)-1 ameliorates myocardial metabolic abnormalities in chronic heart failure. BACKGROUND Albiglutide (GSK716155) is a GLP-1 agonist indicated for type 2 diabetes. METHODS We performed a randomized, placebo-controlled study evaluating 12 weeks of albiglutide in New York Heart Association II or III subjects with ejection fr...

متن کاملExercise testing in pulmonary arterial hypertension and in chronic heart failure.
Exercise capacity is reduced in pulmonary arterial hypertension and in chronic left heart failure, but it is not known whether the cardiopulmonary exercise testing profile is different in the two conditions at the same severity of functional limitation. Nineteen patients with pulmonary arterial hypertension and 19 with chronic heart failure underwent a 6-min walk test and symptom-limited maxima...
متن کاملPeak VO(2): a simple yet enduring standard.
In this issue of Circulation, Pardaens et al 1 examine the prognostic value of cardiopulmonary exercise testing in ambulatory patients with heart failure who are screened for cardiac transplantation. The investigators failed to demonstrate any significant advantage of ventilatory data over peak oxygen uptake (V̇O2). Over the past 10 years, several investigators have attempted to refine the use o...
