Exercise hemodynamics enhance diagnosis of early heart failure with preserved ejection fraction.
BACKGROUND When advanced, heart failure with preserved ejection fraction (HFpEF) is readily apparent. However, diagnosis of earlier disease may be challenging because exertional dyspnea is not specific for heart failure, and biomarkers and hemodynamic indicators of volume overload may be absent at rest. METHODS AND RESULTS Patients with exertional dyspnea and ejection fraction >50% were refer...
متن کاملImaging in heart failure with preserved ejection fraction.
Heart failure (HF) with preserved ejection fraction (HFpEF) is becoming the predominant form of HF. Understanding cardiac structure and function in this syndrome is highly relevant for diagnosis, prognosis, pathophysiology, and management. However, identifying cardiac dysfunction in HFpEF can be challenging and requires an integrated assessment of cardiac structure, systolic and diastolic funct...
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...
متن کاملValues of hemodynamic variation in response to passive leg raising in predicting exercise capacity of heart failure with preserved ejection fraction
In heart failure patients with preserved ejection fraction, their hemodynamic parameters usually change when they are from recumbent to passive leg raising. The authors designed this study to investigate the relationship between hemodynamic parameters measured by impedance cardiography (ICG) and 6-minute walk distance (6MWD) of heart failure with preserved ejection fraction (HFPEF). We recruite...
متن کاملEchocardiography and invasive hemodynamics during stress testing for diagnosis of heart failure with preserved ejection fraction: an experimental study.
Inclusion of exercise testing in diagnostic guidelines for heart failure with preserved ejection fraction (HFpEF) has been advocated, but the target population, technical challenges, and underlying pathophysiological complexity raise difficulties to implementation. Hemodynamic stress tests may be feasible alternatives. Our aim was to test Trendelenburg positioning, phenylephrine, and dobutamine...
