Blood Pressure Variability in Acute Ischemic Stroke: Current Evidence, Measurement Challenges, and Future Directions

The Journal of Clinical Hypertension, Volume 28, Issue 7, July 2026.
ABSTRACT Blood pressure variability (BPV) has emerged as a prognostic hemodynamic marker in acute ischemic stroke (AIS), with observational studies consistently associating early systolic fluctuations with infarct progression, neurological deterioration, hemorrhagic transformation, and worse functional outcomes.

Oxidative stress and impaired cardiovagal baroreflex sensitivity in young adults with post‐traumatic stress disorder

Experimental Physiology, Volume 111, Issue 7, Page 3216-3227, 1 July 2026.
Abstract Post‐traumatic stress disorder (PTSD) is associated with elevated cardiovascular disease (CVD) risk, yet the underlying physiological characterization in young adults remain unclear. This study examines whether autonomic and/or vascular dysfunction predominates as an early precursor to CVD development in young adults with PTSD and explores the

Autonomic control of cardiac rhythm at the onset of muscle metaboreflex activation following exercise in healthy young and old adults

Physiological Reports, Volume 14, Issue 13, July 2026.
Healthy young adults exhibit restoration of parasympathetic nervous system control of cardiac rhythm at the onset of muscle metaboreflex activation following exercise. Conversely, this restoration of parasympathetic nervous system control of cardiac rhythm at the onset of muscle metaboreflex activation following exercise is absent in healthy old adults.
