Contribution of exercise echocardiography to the diagnosis of heart failure with preserved ejection fraction (HFpEF).
OBJECTIVES To examine the contribution of exercise echocardiography (ExE) to the diagnosis of heart failure with preserved ejection fraction (HFpEF). DESIGN Cross-sectional study of patients undergoing ExE. PATIENTS 436 patients with fatigue or dyspnoea presenting for ExE were studied. METHODS Current criteria for the diagnosis of HFpEF (evidence of symptoms or signs of heart failure, EF>...
متن کاملPrognostic Value of Cardiopulmonary Exercise Testing in Heart Failure With Reduced, Midrange, and Preserved Ejection Fraction
BACKGROUND This study aimed to compare the independent and incremental prognostic value of peak oxygen consumption (VO2) and minute ventilation/carbon dioxide production (VE/VCO2) in heart failure (HF) with preserved (HFpEF), midrange (HFmEF), and reduced (HFrEF) ejection fraction (LVEF). METHODS AND RESULTS In 195 HFpEF (LVEF ≥50%), 144 HFmEF (LVEF 40-49%), and 630 HFrEF (LVEF <40%) patients...
متن کاملEchocardiographic predictors of chronotropic incompetence to exercise in patients with heart failure with preserved ejection fraction.
OBJECTIVE Exercise intolerance in patients with heart failure with preserved ejection fraction (HFpEF) is most often attributed to diastolic dysfunction (DD); however, chronotropic incompetence (CI) could also play an important role. We intended to examine whether there are predictive echocardiographic parameters of DD for impaired chronotropic response to exercise. METHODS AND RESULTS Patien...
متن کاملTargeting Endothelial Function to Treat Heart Failure with Preserved Ejection Fraction: The Promise of Exercise Training
Although the burden of heart failure with preserved ejection fraction (HFpEF) is increasing, there is no therapy available that improves prognosis. Clinical trials using beta blockers and angiotensin converting enzyme inhibitors, cardiac-targeting drugs that reduce mortality in heart failure with reduced ejection fraction (HFrEF), have had disappointing results in HFpEF patients. A new "whole-s...
متن کاملContributions of Nondiastolic Factors to Exercise Intolerance in Heart Failure With Preserved Ejection Fraction.
BACKGROUND Heart failure with preserved ejection fraction (HFpEF) has a complex etiology. Factors responsible for development of impaired exercise tolerance and disease progression are incompletely defined. OBJECTIVES The authors sought to define the contributions of contractile reserve, ventriculo-arterial coupling (VAC) reserve, and chronotropic response to the progression of HFpEF. METHO...
