Several attempts have been made, by the scientific community, to develop a unifying
hypothesis that explains the clinical syndrome of heart failure (HF). The currently widely …

Laser Doppler flowmetry (LDF) has long been considered a gold standard for non-invasive
assessment of skin microvascular function. Due to the laser Doppler (LD) microcirculatory …

The low-frequency component of the heart rate variability spectrum (0.06–0.10 Hz) is often
used as an accurate reflection of sympathetic activity. Therefore, interventions that enhance …

BACKGROUND After acute myocardial infarction (AMI), several abnormalities of the
autonomic control to the heart have been described. Heart rate (HR) variability has been …

We studied the neural determinants of the second (ie, high frequency, HF)-and third-order
(ie, low frequency, LF) spontaneous oscillations of heart period (RR interval) and arterial …

Clinical and experimental evidence suggest that sympathoadrenal activation contributes to
mortality in patients with ischemic heart disease. To determine the level of sympathoadrenal …

Activation of the adrenergic nervous system appears to play a crucial role in the genesis of
fatal arrhythmias associated with the very early stages of acute myocardial infarction. The …

Despite considerable progress in management over the recent years, coronary artery
disease (CAD) remains the leading cause of death in the industrialised world. It is estimated …

Acute myocardial infarction (MI) is a major cause of death worldwide. Although timely and
successful reperfusion could reduce myocardial ischemia injury, limit infarct size, and …

The purpose of this study was to determine if clonidine reduces myocardial ischemia or
alters anesthetic requirement and perioperative hemodynamic parameters during coronary …
