Prohormones in the early diagnosis of cardiac syncope [PDF]

, 2017
Background--The early detection of cardiac syncope is challenging. We aimed to evaluate the diagnostic value of 4 novel prohormones, quantifying different neurohumoral pathways, possibly involved in the pathophysiological features of cardiac syncope ...

Haemodynamic‐energetic mechanism of sudden cardiac death in severe aortic stenosis: A modelling study

The Journal of Physiology, EarlyView.
Abstract figure legend A sudden decrease in total peripheral resistance (TPR), as observed during vasovagal syncope, leads to a reduction in aortic systolic pressure (AO pressure) and afterload. In healthy individuals, the consequent decrease in left ventricular systolic pressure (LV pressure) lowers stroke work and myocardial energy expenditure.

Video education to improve clinical skills in the prevention of and response to vasovagal syncopal episodes

International Journal of Women's Dermatology, 2020
Background: Vasovagal syncope is a common clinical occurrence during routine outpatient dermatology procedures, such as injections and biopsies. Despite its prevalence, many medical students and health care professionals do not know how to respond ...

Determinants of maximal oxygen uptake in highly trained females and males: a mechanistic study of sex differences using advanced invasive methods

The Journal of Physiology, EarlyView.
Abstract figure legend The results from this study show that maximal cardiac output, stroke volume and leg blood flow are similar between highly trained females and males after normalisation to lean body mass (LBM). However, the 10% higher haemoglobin concentration ([Hb]) and arterial O2 content in males result in higher systemic and leg O2 delivery ...

Tilt Test as a Primary Non-Invasive Method for Testing Cardiac Autonomic Nervous System Function in Patients with Vasovagal Syncope

Український журнал серцево-судинної хірургії
Introduction Syncope is a sudden, brief loss of consciousness with rapid spontaneous recovery, caused by transient global cerebral hypoperfusion. Among various causes of syncope, the most common are reflex mechanisms, particularly vasovagal syncope ...

Serious outcomes among emergency department patients with presyncope: A systematic review

Academic Emergency Medicine, Volume 33, Issue 1, January 2026.
Abstract Background Syncope is transient loss of consciousness, and in presyncope, patients experience same prodromal symptoms without losing consciousness. While studies have extensively reported the risk of serious outcome among emergency department (ED) syncope, the outcome for patients with presyncope and their management are not well studied.

Original paper
Heart rate variability in patients with recurrent syncope

Archives of Medical Science, 2006
Introduction: The autonomic nervous system participates in the pathophysiology of vasovagal syncope. The disturbances in the autonomic nervous system can be measured by heart rate variability (HRV).

Auricular Acupuncture for Facial Aesthetics: A Preliminary Retrospective Clinical Study of 217 Cases

Journal of Cosmetic Dermatology, Volume 25, Issue 1, January 2026.
ABSTRACT Objective In recent years, acupuncture has gained attention as a safe and natural method in cosmetic medicine. Auricular acupuncture has been insufficiently studied in the field of facial aesthetics. Our previous clinical observations were associated with rapid facial tightening, lifting, and slimming following auricular acupuncture, which is ...

Head-Up Tilt Testing with Different Nitroglycerin Dosages: Experience in Elderly Patients with Unexplained Syncope [PDF]

, 2008
AIMS: Protocols using sublingual nitrates have been increasingly used to improve diagnostic accuracy of head-up tilt testing (HUT). Nevertheless, exaggerated responses to nitrates have been frequently described, particularly in elderly patients.

Syncope in a 76‐Year‐Old Male as the Initial Manifestation of a Large, Space‐Occupying Frontotemporo‐Parietal Arachnoid Cyst

Clinical Case Reports, Volume 13, Issue 12, December 2025.
ABSTRACT Examination of a first‐time syncope in a 76‐year‐old man revealed a large, space‐occupying arachnoid cyst almost completely occupying the left frontal, parietal, and temporal lobes and showing a midline shift to the right. Syncope can be the initial clinical manifestation of a space‐occupying arachnoid cyst.
