BACKGROUND Epicardial fat tissue has unique endocrine and paracrine functions that affect the cardiac autonomic system. The head-up tilt test (HUTT) is a simple non-invasive measurement that assesses autonomic nervous system dysfunction. We investigated the association between epicardial fat thickness (EFT) and autonomic neural tone, such as vagal tone. METHODS A total of 797 consecutive pati...

Coronary artery events requiring intervention are associated with depressed cardiac autonomic function. Whether a 6-week cardiac rehabilitation (CR) differs in effectiveness in improving exercise capacity (6MWT), cardiorespiratory function (peakVO2), and autonomic function (HRV) following either cardiac bypass surgery (CABG) or percutaneous coronary revascularization (PCI) is unknown. The curre...

results all variables reached a peak at 1 minute post-jump. salivary alpha-amylase, galvanic skin responses and heart rate did not return to basal value at 90 minutes post-jump, while cortisol returned to basal value at 90 minutes post-jump. conclusions this evidence indicates that parachute jumping is accompanied by a dissociation of sns and hpa response patterns in novice parachutists, showin...

OBJECTIVE Dysfunction of cardiac autonomic nerve system is considered as one of risk factors for coronary atherosclerotic heart disease. Heart rate variability (HRV) has been used to study the correlation between damage of coronary artery and dysfunction of autonomic nervous system. We hypothesize the correlation between damage of coronary artery and dysfunction of autonomic nervous system by H...

conclusion: although timi grade 3 flows trended to be higher in the patients who received early tirofiban in the emergency ward, the difference did not constitute statistical significance and possible benefits, therefore, require further clarification. results: the study population had a mean age of 57.17 ± 10.09 years and included 79.3 % males. timi grade 3 flow was seen in 15 (21.4 %) patient...

OBJECTIVE To study the effects of 6 months exercise training on ventricular remodelling and autonomic tone in patients with acute myocardial infarction and percutaneous coronary intervention. DESIGN Single-blinded randomized control trial. PARTICIPANTS Sixty patients with acute myocardial infarction who had undergone percutaneous coronary intervention. METHODS The exercise group followed ...

Heart rate variability reflects the activity of autonomic nervous system. The aim was to evaluate the value of short-term spectral analysis of heart rate for monitoring the effects of exercise training on the autonomic nervous system in subjects following myocardial infarction. Short-term spectral analysis of heart rate variability was performed during standardised supine-standing-supine test i...
