Opening closed inward rectifier potassium channel doors

British Journal of Pharmacology, Volume 183, Issue 10, Page 2197-2218, May 2026.
Inwardly rectifying potassium (KIR) channels are essential regulators of membrane potential in excitable and non‐excitable tissues. Although KIR channels exhibit a biophysical preference for potassium influx due to voltage‐dependent block of outward current by polyamines and Mg2+, under physiological conditions, they predominantly mediate K+ efflux ...

Prehospital Risk Stratification Using Unsupervised Machine Learning in STEMI

European Journal of Clinical Investigation, Volume 56, Issue 5, May 2026.
Machine learning identified three phenotypes with 30‐day mortality of 3.4%, 22.1%, and 75%. Phenotype‐2 reveals an "occult high‐risk" group: hemodynamically stable yet six‐fold higher mortality. ABSTRACT Background ST‐elevation myocardial infarction (STEMI) exhibits substantial clinical heterogeneity complicating prehospital risk stratification ...

Knowledge and Attitudes Towards ECG Interpretation Among Intensive Care Nurses: A Greek Cross‐Sectional Study

Nursing in Critical Care, Volume 31, Issue 3, May 2026.
ABSTRACT Background Timely recognition of cardiac arrhythmias is essential in Intensive Care Units (ICUs). Electrocardiogram (ECG) interpretation is a core component of nursing practice, yet international studies show persistent gaps. In Greece, limited evidence exists regarding ICU nurses' interpretation, educational preparedness and role perception ...

Pulsed Field Ablation for Atrial Fibrillation in Patients With Obesity: Procedural and Clinical Outcomes

Pacing and Clinical Electrophysiology, Volume 49, Issue 5, Page 636-643, May 2026.
ABSTRACT Background Procedural and clinical outcomes in patients with obesity undergoing catheter ablation for atrial fibrillation (AF) have been mixed. Clinical data in the context of pulsed field ablation (PFA) are currently limited in this patient cohort.

Technical Feasibility of the RHYTHMIA Mapping System in Pediatric Patients Weighing Less Than 20Kg

Pacing and Clinical Electrophysiology, Volume 49, Issue 5, Page 523-530, May 2026.
ABSTRACT Background Catheter ablation in pediatric patients remains technically challenging. The RHYTHMIA high‐density mapping system is increasingly used in pediatric electrophysiology; however, procedural experience in patients weighing less than 20 kg is limited.
