(Circulation) Full episode page: https://podcast.explainheart.com/podcast/ai-electrocardiogram-screens-chagas-disease-09-09-26/ Featured Articles Article 1: HNRNPK Lactylation Amplifies Inflammation and Exacerbates Myocardial Ischemia/Reperfusion Injury by Regulating Jag2 Splicing. Journal: Circulation PubMed Link: https://pubmed.ncbi.nlm.nih.gov/42708184 Summary: The study identified that myocardial ischemia/reperfusion injury involves profound metabolic reprogramming and lactate accumulation. It uncovered that lactylation, a lactate-derived posttranslational modification, links this metabolic stress to aberrant R. N. A. splicing and cardiac inflammation. The R. N. A.-binding protein HNRNPK, or heterogeneous nuclear ribonucleoprotein K, was found to mediate this connection. This reveals a critical regulatory pathway for inflammatory gene expression in the context of ischemia/reperfusion injury. Article 2: Overcoming Intrinsic Barriers in Myofibroblasts Permits Efficient Cardiac Reprogramming After Infarction. Journal: Circulation PubMed Link: https://pubmed.ncbi.nlm.nih.gov/42708181 Summary: The study demonstrated that direct reprogramming of cardiac fibroblasts into induced cardiomyocytes offers a promising strategy for heart regeneration. It revealed that after myocardial infarction, quiescent cardiac fibroblasts activate and differentiate into myofibroblasts, which drive pathological cardiac fibrosis. The research established that converting these injury-activated myofibroblasts into induced cardiomyocytes can simultaneously alleviate fibrosis and replenish lost cardiomyocytes. This indicates that overcoming intrinsic barriers in myofibroblasts is crucial for achieving efficient cardiac reprogramming. Article 3: YAP Promotes Microtubule Growth to Facilitate Sarcomere Disassembly in Adult Cardiomyocytes. Journal: Circulation PubMed Link: https://pubmed.ncbi.nlm.nih.gov/42578265 Summary: The study discovered that the protein YAP, Yes Associated Protein, actively promotes microtubule growth in adult cardiomyocytes. This promotion of microtubule growth facilitates the disassembly of sarcomeric structures. Sarcomere disassembly was found to be essential for adult cardiomyocytes to dedifferentiate into a fetus-like state, enabling successful cell division. These findings clarify a key regulatory mechanism coordinating cardiomyocyte dedifferentiation, cell cycle progression, and sarcomere reorganization. Article 4: Opportunistic Screening for Chagas Disease Using an Artificial Intelligence-Enabled ECG: Prospective Evaluation of Feasibility and Diagnostic Accuracy. Journal: Circulation PubMed Link: https://pubmed.ncbi.nlm.nih.gov/42576808 Summary: The study demonstrated the feasibility of opportunistic screening for Chagas disease using an artificial intelligence-enabled electrocardiogram model. It established the diagnostic accuracy of this A. I.-E. C. G. model, which was further enhanced with three epidemiological questions for improved detection. This approach was found to enable earlier detection of unrecognized Chagas disease infections in a prospective evaluation. The findings support the use of this A. I.-E. C. G.-E. P. I. model as a valuable tool for timely antiparasitic therapy or optimized cardiac care. Article 5: COL1A1-Enhanced CD44/SLC7A11 Interaction and Cystine Uptake Result in CD34+ Foam-Like Macrophage Accumulation in Transplant Arteriosclerosis. Journal: Circulation PubMed Link: https://pubmed.ncbi.nlm.nih.gov/42549511 Summary: The study uncovered that chronic transplant arteriosclerosis, a primary cause of long-term graft failure, involves the accumulation of C. D. 34 positive foam-like macrophages. It revealed that this accumulation is driven by an enhanced interaction between C. D. 44 and S. L. C. 7 A. 11, which is promoted by C. O. L. 1 A. 1. This enhanced interaction was found to increase cystine uptake, contributing to the formation of these specific macrophage subpopulations. The findings elucidate crucial origins and regulatory mechanisms of inflammatory macrophages in allograft arteriosclerosis, providing targets for therapy.

(Circulation) Full episode page: https://podcast.explainheart.com/podcast/macrotroponin-i-lower-mortality-risk-09-09-26/ Featured Articles Article 1: Tozorakimab to Prevent COPD Exacerbations. Journal: The New England journal of medicine PubMed Link: https://pubmed.ncbi.nlm.nih.gov/42708515 Summary: Tozorakimab is a monoclonal antibody that inhibits interleukin-33 activity, a key mechanism implicated in the pathogenesis of chronic obstructive pulmonary disease. This therapeutic approach targets the dysregulated signaling in patients who continue to experience exacerbations despite standard-of-care inhaled maintenance therapy. The OBERON and TITANIA phase three trials investigated tozorakimab for preventing exacerbations in adults with chronic obstructive pulmonary disease who were current or former smokers and had a history of exacerbations. The clinical focus is on providing a new preventative option for this high-risk patient population. Article 2: Impaired Glycolysis Leads to Defective Efferocytosis and Impaired Plaque Resolution in Tet2 Clonal Hematopoiesis. Journal: Circulation PubMed Link: https://pubmed.ncbi.nlm.nih.gov/42708224 Summary: The study found that TET2 (tet methylcytosine dioxygenase two) clonal hematopoiesis impairs glycolysis in macrophages. This impaired glycolysis leads to defective efferocytosis, consequently resulting in impaired plaque resolution within atherosclerotic plaques. The data showed that TET2 clonal hematopoiesis promotes atherosclerosis progression. These mechanisms were observed to impair plaque remodeling and regression even under conditions of low-density lipoprotein lowering. Article 3: Macrotroponin Complexes and Risk of Cardiovascular Events. Journal: Circulation PubMed Link: https://pubmed.ncbi.nlm.nih.gov/42708217 Summary: The study found that macrotroponin complexes were present in a general population cohort of 19499 participants, with macrotroponin I found in 0.8 percent and macrotroponin T in 0.2 percent. Results showed that macrotroponin I was associated with a lower risk of all-cause mortality, with a hazard ratio of 0.61 and a 95 percent confidence interval of 0.46 to 0.80. This association for macrotroponin I also extended to cardiovascular mortality, showing a hazard ratio of 0.52 with a 95 percent confidence interval of 0.30 to 0.90, even after adjusting for cardiac troponin levels and confounders. No significant association was observed between macrotroponin T and clinical outcomes. Article 4: Arrhythmic Risk Stratification According to LGE Corridors and Genetics in Nonischemic Dilated Cardiomyopathy. Journal: Circulation PubMed Link: https://pubmed.ncbi.nlm.nih.gov/42708210 Summary: The study found that late gadolinium enhancement (L. G. E.) corridors, assessed through cardiac magnetic resonance imaging, were an independent predictor of major ventricular arrhythmic events in nonischemic dilated cardiomyopathy, showing a hazard ratio of 2.1 with a P value less than 0.001. High-risk genotypes were also identified as an independent predictor, with a hazard ratio of 2.0 and a P value less than 0.001. Patients exhibiting both L. G. E. corridors and high-risk genotypes faced a five-fold higher risk of major ventricular arrhythmic events compared to those without either factor, achieving a hazard ratio of 5.0 with a P value less than 0.001. This combined risk stratification approach identified 79 percent of major ventricular arrhythmic events within 28 percent of the cohort at three years. Article 5: An Updated Evidence Assessment of the Genetic Causes of Dilated Cardiomyopathy. Journal: Circulation PubMed Link: https://pubmed.ncbi.nlm.nih.gov/42708185 Summary: The Clinical Genome Resource Dilated Cardiomyopathy gene curation expert panel reconvened to conduct an updated evidence assessment of genes associated with dilated cardiomyopathy. This reassessment applied the Clinical Genome Resource semiquantitative clinical validity classification framework, with specific parameters for dilated cardiomyopathy, to classify the implicated disease genes. The work provides an updated classification of the diverse genetic architecture of dilated cardiomyopathy.

Journal: European heart journal PubMed Link: https://pubmed.ncbi.nlm.nih.gov/42568051 Summary: Endometriosis affects approximately 10 percent of women of reproductive age, with evidence linking it to systemic inflammation. This inflammatory process creates a recognized potential for increased venous thromboembolism risk. A Danish nationwide, registry-based cohort study comprehensively included all women with endometriosis from 1977 to 2024. The study rigorously matched these individuals 1 to 4 with controls based on birth and index year, representing a substantial effort to understand the association of endometriosis with long-term venous thromboembolism. Article 2: Temporal comparison of clinical practice and outcomes in heart failure: the JROADHF and JROADHF-NEXT studies. Journal: European heart journal PubMed Link: https://pubmed.ncbi.nlm.nih.gov/42568038 Summary: Heart failure management has seen significant therapeutic and interventional advances; however, real-world clinical practice remains poorly characterized. This investigation utilized two major Japanese heart failure registries: JROADHF from 2013, comprising 13238 patients, and JROADHF-NEXT from 2019 to 2021, comprising 4016 patients. Patient outcomes were rigorously compared between the cohorts using 1-to-1 propensity score matching. This extensive comparison provides a temporal evaluation of heart failure management and its impact on outcomes.

A. Donor-Specific Antibody. Late graft survival following pediatric heart transplantation is inadequate, primarily due to chronic rejection. Daratumumab has demonstrated promise for treating antibody-mediated rejection, though published experience in heart transplantation is limited. This study retrospectively analyzed heart transplantation recipients who received daratumumab at a dose of 16 milligrams per kilogram for four doses. Treatment was administered for antibody-mediated rejection identified by elevated donor-derived cell-free D. N. A., without graft dysfunction or hemodynamic compromise, and confirmed by endomyocardial biopsy.

Journal: The Journal of heart and lung transplantation : the official publication of the International Society for Heart Transplantation PubMed Link: https://pubmed.ncbi.nlm.nih.gov/42567379 Summary: Cardiac allograft vasculopathy significantly limits longevity following heart transplantation. Non-invasive physiological assessment using cardiac positron emission tomography offers established prognostic significance for this condition. This investigation included all adult single-organ heart transplant recipients who underwent Nitrogen-13 ammonia positron emission tomography myocardial perfusion imaging between 2016 and 2019. The study performed a median follow-up to measure the prognostic contribution of stress myocardial blood flow and myocardial blood flow reserve to post-transplant outcomes. Article 5: Impact of empagliflozin on serum calcium and phosphate in heart failure. Journal: Journal of cardiac failure PubMed Link: https://pubmed.ncbi.nlm.nih.gov/42567257 Summary: Alterations in serum calcium and phosphate balance are associated with poor outcomes in heart failure, with existing data primarily from small observational studies. The effect of sodium-glucose cotransporter two inhibitors on serum calcium and phosphate levels has not been thoroughly examined in large, randomized heart failure trials. This study utilized comprehensive data from the EMPEROR-Pooled trials. The analysis focused on evaluating the prognostic associations of serum calcium and phosphate in heart failure patients and the specific impact of sodium-glucose cotransporter two inhibitors on these levels.

Article number two. Temporal comparison of clinical practice and outcomes in heart failure: the JROADHF and JROADHF-NEXT studies. Heart failure management has seen significant therapeutic and interventional advances; however, real-world clinical practice remains poorly characterized. This investigation utilized two major Japanese heart failure registries: JROADHF from 2013, comprising 13238 patients, and JROADHF-NEXT from 2019 to 2021, comprising 4016 patients. Patient outcomes were rigorously compared between the cohorts using 1-to-1 propensity score matching. This extensive comparison provides a temporal evaluation of heart failure management and its impact on outcomes. Article number three. Daratumumab for Non-Acute Antibody-Mediated Rejection After Pediatric Heart Transplantation: Treatment Response in the Presence and Absence of Circulating H. L. A. Donor-Specific Antibody. Late graft survival following pediatric heart transplantation is inadequate, primarily due to chronic rejection. Daratumumab has demonstrated promise for treating antibody-mediated rejection, though published experience in heart transplantation is limited. This study retrospectively analyzed heart transplantation recipients who received daratumumab at a dose of 16 milligrams per kilogram for four doses. Treatment was administered for antibody-mediated rejection identified by elevated donor-derived cell-free D. N. A., without graft dysfunction or hemodynamic compromise, and confirmed by endomyocardial biopsy. Article number four. Prognostic Significance of Myocardial Blood Flow Reserve and Stress Myocardial Blood Flow in the Assessment of Cardiac Allograft Vasculopathy in Heart Transplant Recipients. Cardiac allograft vasculopathy significantly limits longevity following heart transplantation. Non-invasive physiological assessment using cardiac positron emission tomography offers established prognostic significance for this condition. This investigation included all adult single-organ heart transplant recipients who underwent Nitrogen-13 ammonia positron emission tomography myocardial perfusion imaging between 2016 and 2019. The study performed a median follow-up to measure the prognostic contribution of stress myocardial blood flow and myocardial blood flow reserve to post-transplant outcomes. Article number five. Impact of empagliflozin on serum calcium and phosphate in heart failure. Alterations in serum calcium and phosphate balance are associated with poor outcomes in heart failure, with existing data primarily from small observational studies. The effect of sodium-glucose cotransporter two inhibitors on serum calcium and phosphate levels has not been thoroughly examined in large, randomized heart failure trials. This study utilized comprehensive data from the EMPEROR-Pooled trials. The analysis focused on evaluating the prognostic associations of serum calcium and phosphate in heart failure patients and the specific impact of sodium-glucose cotransporter two inhibitors on these levels.

Journal: Circulation PubMed Link: https://pubmed.ncbi.nlm.nih.gov/42546101 Summary: Left ventricular hypertrabeculation, previously known as left ventricular noncompaction, represents a heterogeneous myocardial condition. This study found that the presence of hypertrabeculation in patients with dilated cardiomyopathy (D. C. M.) correlated with an altered embolic risk profile. The research determined its prevalence and established its prognostic relevance across various dilated cardiomyopathy genotypes. These findings provide crucial information for understanding patient stratification and risk assessment in dilated cardiomyopathy. Article 2: Association of Pulmonary Vascular Remodeling With Cardiac Structure and Function, Pulmonary Pressure, and Heart Failure in Late Life: The Atherosclerosis Risk in Communities (ARIC) Study. Journal: Circulation PubMed Link: https://pubmed.ncbi.nlm.nih.gov/42478373 Summary: This study found a significant association between pulmonary vascular arterial remodeling, characterized by distal pruning and proximal dilation, and various cardiac parameters. Specifically, it demonstrated correlations with cardiac structure and function, including age-associated left ventricular remodeling and diastolic dysfunction. The research established links between these pulmonary arterial changes and elevated pulmonary pressure, as well as the incidence of heart failure in late life. These findings highlight the interplay between pulmonary vascular health and cardiac function in an aging population. Article 3: Loss of STMP1 Perturbs Mitochondrial Cristae and Drives Cellular Inflammation and Heart Failure. Journal: Circulation PubMed Link: https://pubmed.ncbi.nlm.nih.gov/42267405 Summary: This study found that the loss of STMP1 significantly perturbs mitochondrial cristae integrity within cells. Compromised mitochondrial cristae led to a cytoplasmic leak of mitochondrial D. N. A., which in turn triggered persistent low-grade cellular inflammation. This inflammatory response occurred through the activation of the cGAS (cyclic G. M. P. A. M. P. synthase)-STING (stimulator of interferon genes) pathway and subsequently type one interferon. The research concluded that this mechanistic pathway driven by STMP1 loss actively drives cellular inflammation and contributes to the progression of heart failure. Article 4: SREBP1 Transactivation of NHE3 Impairs Cardiac Contraction and Aggravates Heart Failure. Journal: Circulation PubMed Link: https://pubmed.ncbi.nlm.nih.gov/42170742 Summary: This study found that sterol regulatory element-binding protein one (S. R. E. B. P. one) transactivation of sodium hydrogen exchanger three (N. H. E. three) directly impairs cardiac contraction. The research demonstrated that this pathway contributes to the dysregulation of intracellular ion cycling, specifically sodium and hydrogen, which is fundamental to reduced cardiac contractility. The findings revealed a critical mechanism linking myocardial stress to these ion imbalances. Ultimately, the study concluded that S. R. E. B. P. one transactivation of N. H. E. three aggravates heart failure, particularly heart failure with reduced ejection fraction (H. F. r. E. F.). Article 5: Markers of ultra-processed food and incident arterial hypertension in the UK Biobank. Journal: European heart journal PubMed Link: https://pubmed.ncbi.nlm.nih.gov/42545878 Summary: This prospective cohort study, involving 101560 non-hypertensive U. K. Biobank participants, found a positive association between the intake of ultra-processed food (U. P. F.) and incident arterial hypertension. The research specifically assessed and identified associations with particular markers of ultra-processing (M. U. P. s) that had not been previously evaluated. Participants’ dietary intake was captured via 24-hour dietary recalls, and ultra-processed foods were identified by matching commercial products to food items. The data demonstrated that specific markers within ultra-processed foods independently correlated with the development of new-onset hypertension. Transcript Today’s date is August 04, 2026.

The research demonstrated that this pathway contributes to the dysregulation of intracellular ion cycling, specifically sodium and hydrogen, which is fundamental to reduced cardiac contractility. The findings revealed a critical mechanism linking myocardial stress to these ion imbalances. Ultimately, the study concluded that S. R. E. B. P. one transactivation of N. H. E. three aggravates heart failure, particularly heart failure with reduced ejection fraction (H. F. r. E. F.). Article number five. Markers of ultra-processed food and incident arterial hypertension in the UK Biobank. This prospective cohort study, involving 101560 non-hypertensive U. K. Biobank participants, found a positive association between the intake of ultra-processed food (U. P. F.) and incident arterial hypertension. The research specifically assessed and identified associations with particular markers of ultra-processing (M. U. P. s) that had not been previously evaluated. Participants’ dietary intake was captured via 24-hour dietary recalls, and ultra-processed foods were identified by matching commercial products to food items. The data demonstrated that specific markers within ultra-processed foods independently correlated with the development of new-onset hypertension. Thank you for listening. Don’t forget to subscribe.
