Time-Frequency Analysis of Cardiovascular and Cardiorespiratory Interactions During Orthostatic Stress by Extended Partial Directed Coherence

Entropy, 2019
In this study, the linear method of extended partial directed coherence (ePDC) was applied to establish the temporal dynamic behavior of cardiovascular and cardiorespiratory interactions during orthostatic stress at a 70° head-up tilt (HUT) test on ...

Cerebrovascular regulation during heat stress

Experimental Physiology, EarlyView.
Abstract Given that the brain is a highly metabolic organ and is enclosed by the skull, effective regulation of cerebral blood flow (CBF), not only for oxygen and nutrients supply but also as a means of convective heat exchange, is critical for preventing excessive elevations in brain temperature.

Apical hypercontractility mitigates impaired diastolic filling and lower intraventricular haemodynamic forces in human bed rest

Experimental Physiology, EarlyView.
Abstract Prolonged physical inactivity alters the cardiovascular system, including the heart. Long‐term bed rest is known to decrease left ventricular volume and cause diastolic dysfunction; however, the interplay between these changes and their effect on cardiac contractility have been understudied.

Clinical profile and cardiovascular autonomic function tests in patients with postural orthostatic tachycardia syndrome

CHRISMED Journal of Health and Research, 2019
Background: Postural orthostatic tachycardia syndrome (POTS) is an autonomic disorder characterized by the clinical symptoms of orthostatic intolerance such as light-headedness, fatigue, sweating, tremor, anxiety, palpitation, exercise intolerance, and ...

Epidural Spinal Cord Stimulation of Lumbosacral Networks Modulates Arterial Blood Pressure in Individuals With Spinal Cord Injury-Induced Cardiovascular Deficits

Frontiers in Physiology, 2018
Disruption of motor and autonomic pathways induced by spinal cord injury (SCI) often leads to persistent low arterial blood pressure and orthostatic intolerance.

Dose‐dependent effects of graded altered gravity during hypovolaemia on central haemodynamics and cardiovascular autonomic regulation

Experimental Physiology, EarlyView.
Abstract The cardiovascular system is strongly influenced by gravitational loading and blood volume status. Quantifying central haemodynamic and autonomic reflex responses to fluid redistribution is important in altered‐gravity conditions, with relevance to spaceflight and clinical medicine.

Clinical Practice Guideline for Evaluation and Management of Peripheral Nervous System Manifestations in Sjögren's Disease

Arthritis Care &Research, Volume 78, Issue 7, Page 860-874, July 2026.
Objective Sjögren's disease is an autoimmune disorder that can impact multiple organ systems, including the peripheral nervous system (PNS). PNS manifestations, which can exist concurrently, include mononeuropathies, polyneuropathies, and autonomic nervous system neuropathies.
