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 ...

The Social, Decoupled Self: Interpersonal Synchronization of Breathing Alters Intrapersonal Cardiorespiratory Coupling

Annals of the New York Academy of Sciences, Volume 1559, Issue 1, May 2026.
When two people synchronize their breathing together, their heart rhythms also synchronize, while their intrapersonal cardiorespiratory rhythms become decoupled, with a perturbed phase‐relationship between respiration and cardiac rhythms. Across two experiments, stronger interpersonal respiratory synchronization was associated with more pronounced ...

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.

Transjugular Leadless Pacemaker Implantation in an Adolescent With Central Hypoventilation Syndrome: A Case Report

Pacing and Clinical Electrophysiology, Volume 49, Issue 5, Page 606-609, May 2026.
ABSTRACT Background Permanent pacing in pediatric patients is complicated by small body size, vascular access limitations, and the need for durable long‐term management. Leadless pacemakers offer an emerging alternative that minimizes infection and lead‐related complications, yet vascular access remains a key challenge in young patients.

Acute cardiovascular responses to slow and deep breathing in normotensive men and women

Experimental Physiology, Volume 111, Issue 5, Page 2494-2517, 1 May 2026.
Abstract Slow and deep breathing is recommended as an effective treatment for hypertension using the RESPeRATE device. However, the acute cardiovascular responses to slow and deep breathing, including the potential mechanisms underlying its antihypertensive effect, are not fully understood. This study characterised the acute cardiovascular responses to
