Journal: Circulation PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41878819 Summary: Left ventricular assist device support improves cardiac histology and function in patients with heart failure. This improvement sometimes allows patients to avoid heart transplantation after Left Ventricular Assist Device removal. The study investigated the microvascular and cellular programs underlying this observed myocardial recovery. Article 2: The Fontan Outcomes Network: Findings After 2 Years and 1121 Participants. Journal: Circulation PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41878814 Summary: Survival after Fontan palliation for single ventricle heart disease has substantially improved. The Fontan Outcomes Network, comprising 38 congenital heart centers, was established to define the long-term trajectory of these patients. The network successfully enrolled 1121 participants within its first two years, providing a substantial cohort for future longitudinal analysis. Article 3: Association Between Copayments and Attendance in Cardiac Rehabilitation: A Nationwide Analysis From the AACVPR Registry. Journal: Journal of the American Heart Association PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41878870 Summary: A. C. V. P. R. Registry. Improving cardiac rehabilitation participation remains a national priority. This study utilized the American Association of Cardiovascular and Pulmonary Rehabilitation registry, analyzing data from 2012 to 2021. The investigation explored the relationship between patient copayments and attendance in cardiac rehabilitation programs, and also patient dropout rates. This analysis addressed the crucial clinical question of how financial barriers impact patient adherence and program completion. Article 4: Sociodemographic and Clinical Predictors of Mortality in Adults With Congenital Heart Disease. Journal: Journal of the American Heart Association PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41878868 Summary: Mortality in adults with congenital heart disease is strongly driven by disease complexity. This study investigated the influence of both clinical factors and social determinants of health on all-cause mortality in patients with adult congenital heart disease. Researchers utilized a single-center retrospective cohort from the Mayo Adult Congenital Heart Disease Registry, spanning from 2004 to 2017. The findings contributed to understanding critical factors impacting long-term survival in this complex patient population. Article 5: Joint Associations of Sleep Patterns and Genetic Susceptibility With Dynamic Transitions of Chronic Obstructive Pulmonary Disease and Coronary Heart Disease and the Mediating Role of Inflammatory Biomarkers and Metabolites. Journal: Journal of the American Heart Association PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41878867 Summary: Sleep behaviors influence the development of both chronic obstructive pulmonary disease and coronary heart disease. This study explored the associations of specific sleep patterns with dynamic transitions of these conditions. The investigation also addressed the interaction of sleep patterns with genetic susceptibility and the mediating role of inflammatory biomarkers and metabolites. The analysis utilized extensive data from the U. K. Biobank to characterize these complex interrelationships affecting comorbidity. Transcript Today’s date is March 25, 2026.
