Article 1: Learning Curve and Procedural Efficiency of Zero-Fluoroscopy Pulsed-Field Ablation for Atrial Fibrillation.
Journal: Heart rhythm
PubMed Link: https://pubmed.ncbi.nlm.nih.gov/40975149
Summary: This study compared zero-fluoroscopy radiofrequency ablation and pulsed-field ablation for paroxysmal atrial fibrillation. Pulsed-field ablation demonstrated significantly shorter procedure times and left atrial dwell times compared to radiofrequency ablation, indicating improved procedural efficiency with similar acute outcomes in experienced centers. These findings suggest pulsed-field ablation may offer advantages in workflow and resource utilization without compromising safety in experienced hands.
Article 2: Population-Based Study on the Coexistence of Metabolic Dysfunction-Associated Steatotic Liver Disease and Chronic Kidney Disease.
Journal: Journal of the American Heart Association
PubMed Link: https://pubmed.ncbi.nlm.nih.gov/40970538
Summary: This study using National Health and Nutrition Examination Survey data from 2007 to 2018 found that coexistence of metabolic dysfunction-associated steatotic liver disease and chronic kidney disease was associated with a significantly increased risk of all-cause mortality compared to either condition alone. The increased mortality risk highlights the importance of identifying and managing both conditions concurrently to improve patient outcomes. Specifically, the hazard ratio for all-cause mortality was significantly elevated when both conditions were present.
Article 3: Dynamic Increase of the C2HEST Score in Relation to the Development of Incident Atrial Fibrillation: A Longitudinal Cohort Study.
Journal: Journal of the American Heart Association
PubMed Link: https://pubmed.ncbi.nlm.nih.gov/40970537
Summary: This longitudinal study demonstrated that an increasing C2HEST score, reflecting accumulation of risk factors like coronary artery disease, hypertension, and heart failure, is associated with a heightened risk of developing incident atrial fibrillation. A dynamic approach to risk assessment using the C2HEST score, rather than a one-time evaluation, may improve prediction of atrial fibrillation risk over time. Monitoring changes in C2HEST score components offers a practical way to identify individuals at increasing risk.
Article 4: Associations of Immune Cell Subsets With Coronary Artery Calcium Incidence and Progression in the Multi-Ethnic Study of Atherosclerosis.
Journal: Journal of the American Heart Association
PubMed Link: https://pubmed.ncbi.nlm.nih.gov/40970536
Summary: This study from the Multi-Ethnic Study of Atherosclerosis found specific immune cell subsets are associated with both the incidence and progression of coronary artery calcium. Increased CD8-positive T cells and decreased naive B cells were associated with a higher likelihood of coronary artery calcium development, while a higher proportion of regulatory T cells was associated with slower coronary artery calcium progression. These findings suggest that immune cell composition may play a role in the development and progression of subclinical atherosclerosis.
Article 5: New-Onset Atrial Fibrillation During ST-Segment-Elevation Myocardial Infarction: Risk of Recurrence and Its Clinical Impact During 10 Years of Follow-Up.
Journal: Journal of the American Heart Association
PubMed Link: https://pubmed.ncbi.nlm.nih.gov/40970535
Summary: This single-center study showed a high rate of atrial fibrillation recurrence within 10 years among patients who experienced new-onset atrial fibrillation during ST-segment-elevation myocardial infarction. The recurrence of atrial fibrillation was independently associated with increased risks of stroke, systemic embolism, and all-cause mortality. These results underscore the importance of long-term monitoring and appropriate anticoagulation strategies in patients with ST-segment-elevation myocardial infarction who develop new-onset atrial fibrillation.
