Metabolomics in Atrial Fibrillation: Unlocking Novel Biomarkers and Pathways for Diagnosis, Prognosis, and Personalized Treatment.

Atrial fibrillation (AF) is the most frequent arrhythmia in the adult population associated with a high rate of severe consequences leading to significant morbidity and mortality worldwide. Therefore, its prompt recognition is of high clinical importance. AF detection often remains challenging due to unspecific symptoms and a lack of reliable biomarkers for its prediction.

Advanced Speckle-Tracking Echocardiography Could Play a Crucial Role in the Diagnosis of Post-Implanted Cardiomyopathy Associated with a Leadless Pacemaker System.

A leadless pacemaker (LP) is a modern alternative to a transvenous pacemaker, allowing certain complications to be avoided; however, some cannot be eliminated. To highlight the essential role of advanced speckle-tracking echocardiography (STE) in diagnosing pacing-induced cardiomyopathy (PICM) caused by an LP. A 79-year-old male, after LP implantation a year earlier, was admitted due to heart failure (HF).
