Summary: This study aimed to investigate the performance of a newly developed method to analyze electrical wavefront propagation in a heart model and compare it to clinical benchmark studies. The results demonstrated the utility of maximum activation front (MAF) in predicting optimal electrode placements in different pacing scenarios including scar and multi-site LV pacing, showing the potential value of computational simulations in understanding and planning CRT.

Summary: This study evaluated a novel measure for assessing the response to cardiac resynchronization therapy (CRT). The results showed that the standard deviation of regional wall stress at the time of mitral valve closure (SD_MVC) is a significant predictor of therapy response and could potentially improve patient selection for CRT implantation.

Summary: This study reveals a novel biophysical action of endogenous miRs in modulating cardiac electrophysiology through noncanonical mechanisms. Endogenous miR1 physically binds with cardiac membrane protein Kir2.1, suppressing I-K1 and affecting action potential of cardiomyocytes. The findings suggest that miRs may be involved in the pathogenesis of cardiac arrhythmias by regulating ion channel physiology and pathology.

Summary: The optimal timing of CRT implantation remains unknown. In this study of 64,968 patients, delays in time from first HFH to CRT implantation were associated with worse long-term clinical outcomes. Each year from the first HFH to CRT implantation was associated with a higher risk of total mortality and HFH. The best outcomes after CRT were observed in patients with no previous HFHs and in those undergoing implantation during their first HFH.

Summary: This study aimed to evaluate the feasibility of physiological pacing rate (PPR) in cardiac resynchronization therapy (CRT) patients. The results showed that PPR improved functional capacity in mildly symptomatic CRT patients, but further confirmation is needed through controlled randomized trials.

Summary: The delivery of cardiac resynchronization therapy (CRT) for heart failure patients has increased in the past decade. This study aimed to determine whether there have been changes in clinical outcomes after CRT from the perspective of a public healthcare system. The results showed a significant increase in CRT implantations over the years, and despite an increasing comorbidity burden, there was a decrease in mortality and heart failure hospitalizations after CRT implantation.

Summary: Cardiac electrical activity is regulated by ion channels, and transcription factors play a critical role in controlling this activity. They may serve as potential drug targets for treating cardiac arrhythmias.

Summary: This study identified distinct plasma metabolomic profiles in patients with heart failure compared to healthy individuals, with non-responders to CRT showing different metabolomics features, characterized by increased phosphatidylcholines species. A predictive model incorporating four phosphatidylcholines metabolites performed well in identifying CRT non-responders, suggesting their potential role as biomarkers for predicting CRT response. Further validations in larger external cohorts are needed to confirm these findings.

Summary: This study aimed to compare the mortality rates and mode of death in patients with nonischemic cardiomyopathy who were treated with either primary preventive CRT-D or CRT-P. The results showed that CRT-D was associated with higher 5-year survival, especially in patients aged <60 years.

Summary: AP-5/SPG11/SPG15 recruitment is enhanced in starved cells through coincidence detection, requiring both PI3P and Rag GTPases. The FYVE domain of SPG15 plays a crucial role in PI3P binding, with GDP-locked RagC promoting recruitment and GTP-locked RagA preventing it.
