Transgenic mice are widely used to study cardiac function, but strain-dependent differences
in autonomic nervous system activity (ANSA) have not been explored. We compared 1) short …

Our goal was to investigate age-related differences in cardiac autonomic control by means
of heart rate variability (HRV). For this purpose, 30 healthy older and 34 younger adults were …

BACKGROUND: The mechanisms of cardiac remodeling during chronic heart failure remain
poorly defined. We sought to advance a chronic canine model of nonischemic …

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 …

We investigated alterations in autonomic control of heart rate in conscious dogs with left
ventricular (LV) dysfunction in the presence and absence of heart failure (HF) due to rapid …

Background: Frailty is a geriatric syndrome that leads to impairment in interrelated
physiological systems and progressive homeostatic dysregulation in physiological systems …

Background: The aim of this study was to develop a model of long-term progressive heart
failure (HF). Methods and Results: A cardiac output flowprobe was implanted on the …

Despite medical advances in the treatment of heart failure (HF), mortality remains high. It has
been shown that alterations of the autonomic-nervous-system (ANS) are associated with HF …

The responsiveness of the heart to β-adrenergic receptor stimulation declines with age. The
aim of this study was to determine whether food restriction (FR), the most effective means of …

Background—Autonomic dysfunction, characterized by sympathetic activation and vagal
withdrawal, contributes to the progression of heart failure (HF). Although the therapeutic …
