Summary: C. C. / A. H. A. Clinical Performance and Quality Measures for Patients With Peripheral Artery Disease: A Report of the American College of Cardiology/American Heart Association Joint Committee on Performance Measures. The 2026 American College of Cardiology/American Heart Association Clinical Performance and Quality Measures for Patients With Peripheral Artery Disease provide guidance for clinicians, researchers, and quality assurance personnel. These measures establish standards for assessing the effects of treatment decisions, including specific medications and diagnostic tests for individuals with peripheral artery disease. They serve to standardize care and facilitate quality assurance in clinical practice and research for this patient population.

Summary: T. Monitoring to Identify High-Risk Prolongation Events After Class Three Antiarrhythmic Initiation. A deep learning system called 3DRECON-QT was developed for continuous Q. T. monitoring to identify high-risk Q. T. prolongation events. This system addresses drug-induced Q. T. prolongation that can occur after initiation of class three antiarrhythmics during outpatient care. 3DRECON-QT reconstructs spatial information from a single lead vector to quantify Q. T. and Q. T. corrected intervals. Its development provides a novel approach for identifying high-risk Q. T. prolongation, overcoming limitations of current insertable cardiac monitors.

Summary: A multi-omics cohort study investigates the effects of air pollution and meteorological factors on cardiac remodeling in children. A total of 2029 children were enrolled in the Southwest Health Children Cohort in China to provide crucial data on these exposures. This research illuminates how environmental factors influence cardiovascular structure and function and the underlying biomolecular mechanisms in pediatric populations. The study addresses a critical knowledge gap regarding these effects in children, contrasting with established associations in adults.

Summary: L. S. O. Registry Analysis. This Extracorporeal Life Support Organization registry analysis provides real-world outcomes for adults receiving venopulmonary extracorporeal life support. The study utilized a large sample size from the E. L. S. O. registry to describe patient experiences across various clinical conditions. It establishes data regarding the current use, adverse events, and prognostic drivers for venopulmonary extracorporeal life support, where previous information was limited.

Summary: S. This cohort study investigated operator-level procedural volumes and patient outcomes for transcatheter aortic valve replacement and mitral transcatheter edge-to-edge repair in the United States. It examined extensive data from patients undergoing these procedures to determine contemporary associations. The research addresses a critical gap in understanding how individual operator volumes relate to outcomes, particularly as hospital-level associations may be stabilizing. This analysis contributes important information for quality assurance and procedural guideline development in these cardiac interventions.
