Background: Purpose of this study was to examine pupil size changes and mobility in
normal subjects and in heart failure (HF) patients. Methods: Sixteen stable patients with New …

Background: A profound autonomic unbalance is present in heart failure: its correlation with
the etiology of the disease has never been investigated. Aims: We characterized the …

Aims: Autonomic function (AF) is attenuated by heart failure (HF). Reports have been based
on studies of young patients with systolic heart failure (SHF). However, HF is a disease of …

Background: A gradual worsening of autonomic control of cardiovascular function
accompanies the progression of heart failure. Exercise training modulates autonomic …

BACKGROUND: An alteration of the autonomic nervous system has been described in heart
failure (HF). The aim of this study was to assess, compare and relate the impairment of both …

The aim of this study was to evaluate the sympatho-vagal interaction modulating
cardiovascular function and the possible impairment of baroreceptor sensitivity in patients …

Objective: Autonomic dysfunction is an important marker of prognosis in congestive heart
failure (CHF) and may determine the symptoms and progression of CHF. The aim of our …

OBJECTIVES: In patients with severe congestive heart failure (CHF) autonomic dysfunction
has been shown to have a strong predictive value in terms of progression and prognosis …

BACKGROUND: Autonomic dysfunction (AD) is associated with morbidity and mortality in
patients with systolic heart failure (SHF). The extent of AD when LV ejection fraction is …

OBJECTIVE: Several studies documented the relevance of autonomic activity in the
pathophysiology of heart failure. In our study we evaluated the adjustment of this activity …
