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 ...

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 ...

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 ...

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.

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 ...

Direct Single‐Dose Drug‐Provocation Test Is Safe for Delabelling Penicillin Low‐Risk Reactions in Adults

Allergy, Volume 80, Issue 11, Page 3127-3139, November 2025.
We show that direct single‐dose provocation test was both safe and effective in delabeling penicillin allergy in low‐risk adult patients, including those with mild delayed skin reactions and those with unknown reactions, such as childhood labels and past syncope episodes. In those who react in the drug provocation test, a T‐cell mechanism was confirmed

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).

Selatogrel: Potential to redefine timely anti‐platelet intervention

British Journal of Pharmacology, Volume 182, Issue 22, Page 5435-5452, November 2025.
Acute coronary syndrome (ACS) encompasses a number of heart diseases that cause a sudden decrease in coronary perfusion, precipitating cardiomyocyte necrosis or heightened risk thereof. This pathology is a major burden of cardiovascular disease.

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.

Minimizing Atrioesophageal Fistula Risk After AF Ablation: Risk Factors, Prevention, and Emerging Mini‐Thermal Technology

Pacing and Clinical Electrophysiology, Volume 48, Issue 11, Page 1263-1273, November 2025.
ABSTRACT Atrial esophageal fistula (AEF) is a rare but life‐threatening complication of atrial fibrillation (AF) ablation, linked to thermal injuries by conventional radiofrequency (RF) and cryo‐balloon (CB) ablation techniques. AEF risk can be mitigated by considering several measures such as tailored power settings of ablation technique, mechanical ...
