What’s New in Cardiac MRI?

August 17, 2026 · 50 articles · 15 research themes · covering August 10, 2026 – August 17, 2026

Overview

This week’s digest is dominated by advances in cardiovascular imaging—especially cardiac MRI—and by efforts to make imaging more quantitative, scalable, and clinically actionable. Multiple studies focus on tissue characterization (native T1, ECV, fibrosis trajectories, and myocarditis frameworks), including population-specific reference ranges and biomarker validation in real-world cohorts. In parallel, several works push imaging beyond interpretation toward automation: AI systems for structuring cine CMR reports, physics-informed and deep-learning approaches to derive myocardial mechanics or predict post-MI remodeling, and broader reviews on how AI and multimodal integration are reshaping cardiovascular risk assessment.

A second major theme is phenotype-driven cardiology: genotype–phenotype mapping in cardiomyopathies (e.g., arrhythmogenic DCM signatures, Duchenne carrier natural history, and atrial fibrillation calcium-handling variants) and refined heart-failure phenotyping using imaging-derived metrics (including sarcopenic obesity and HFpEF reserve/compliance concepts). Coronary disease research complements this with mechanistic and imaging-linked microvascular dysfunction phenotyping and plaque biology coupling (e.g., high-intensity plaque and pericoronary adipose tissue attenuation). Together, these studies emphasize moving from single “diagnosis labels” toward mechanistic subtypes that can guide prognosis and therapy.

Finally, the digest highlights how imaging and targeted interventions are being adapted to complex clinical contexts—such as iodinated-contrast contraindications, late radiation cardiothoracic complications, and rare cardio-oncology presentations—while also underscoring ongoing translational challenges (e.g., cardioprotection trial neutrality and the need for better trial design). Across these diverse reports, the unifying message is that modern cardiovascular care increasingly relies on multimodality, quantitative biomarkers, and computational tools to reduce diagnostic uncertainty and improve risk stratification in both common and rare disease settings.

Cardiac MRI & Tissue Characterization (Biomarkers, Fibrosis, T1/ECV)

Exercise Cardiovascular Magnetic Resonance Work-Volume Loop Model in Heart Failure with Preserved Ejection Fraction.

The study developed an analytic framework for exercise cardiovascular magnetic resonance (Ex-CMR) to derive non-invasive left ventricular compliance and contractile reserve metrics in people with heart failure with preserved ejection fraction (HFpEF), including stage C overt HFpEF and exercise-induced HFpEF, and to help distinguish exercise-induced HFpEF from non-cardiac dyspnea (NCD). It reports a standardized work-volume loop modeling approach for quantifying reserve independent of a fixed exercise protocol in dyspneic patients with limited capacity. This provides a non-invasive CMR method to better phenotype HFpEF mechanisms (compliance vs contractile reserve) and improve diagnostic discrimination from non-cardiac causes of dyspnea.

Diabetes-associated diffuse myocardial fibrosis assessed by native T1 mapping: Adverse cardiac phenotype and modest incremental prognostic value in a real-world cohort.

In a real-world prospective all-comer registry of patients undergoing cardiac MRI (CMR), the study assessed whether diabetes-associated diffuse myocardial fibrosis measured by native T1 mapping identifies an adverse cardiac phenotype and adds prognostic value beyond established clinical risk factors. Native T1 mapping distinguished diabetes-associated myocardial fibrosis and showed adverse phenotype association with only modest incremental prognostic performance for outcomes including all-cause mortality and heart failure hospitalization. Scientifically, it supports native T1 as a CMR biomarker of diabetes-related remodeling, while suggesting that its incremental prognostic utility may be limited compared with conventional risk models.

Native myocardial T1 reference values in a tunisian cohort using MOLLI and SMART1Map : List of Authors.

This study established native myocardial T1 reference ranges in a Tunisian cohort of 94 healthy volunteers using MOLLI 5(3)3 and SMART1Map CMR sequences and assessed sex- and age-related differences. It also evaluated inter-site variability of MOLLI measurements across two centers using identical scanners and protocols. These population- and sequence-specific reference values improve the clinical interpretability of native T1 for diagnosing myocardial disease in North African populations.

Vutrisiran Treatment and Changes in Cardiac Parameters and Amyloid Burden Assessed by Cardiovascular MRI.

In the HELIOS-B trial analysis, this study evaluated how vutrisiran (an RNA interference therapeutic that suppresses hepatic TTR production) affected cardiac structure/function and amyloid burden measured by multiparametric cardiovascular magnetic resonance (including extracellular volume [ECV] mapping) in patients with transthyretin amyloid cardiomyopathy (ATTR-CM). The key finding was that vutrisiran treatment was associated with measurable changes in CMR cardiac parameters and reductions in amyloid burden as reflected by ECV. Clinically, CMR provides a sensitive biomarker framework to track therapeutic response in ATTR-CM beyond traditional clinical endpoints.

Myocarditis in the Modern Era: Navigating Diagnosis, Innovative Treatments, the COVID-19 Challenge and the Role of Artificial Intelligence.

This narrative review studied modern approaches to myocarditis diagnosis and treatment, focusing on the shift from invasive endomyocardial biopsy toward noninvasive imaging and the impact of COVID-19, including the role of artificial intelligence. It found that cardiac magnetic resonance (CMR) using the Lake Louise Criteria, supplemented by parametric imaging techniques, has significantly improved diagnostic accuracy in the modern era. The clinical significance is that it consolidates current diagnostic pathways and emerging tools (including AI) to better navigate heterogeneous myocarditis presentations and COVID-19–related diagnostic challenges.

New perspectives on chagasic cardiomyopathy: A narrative review of genetics, magnetic resonance imaging and therapeutic alternatives.

This narrative review studied chagasic cardiomyopathy with emphasis on genetics, cardiac magnetic resonance imaging, and therapeutic alternatives in the context of American trypanosomiasis. It found that recent evidence (2020–2026) challenges a simple relationship between parasite lineage and cardiac severity, instead implicating the host inflammatory response as a primary driver, while summarizing the diagnostic utility of CMR and evolving treatment options. The clinical significance is that it frames updated risk stratification and diagnostic strategy for Chagas cardiomyopathy, particularly in settings like Peru where delayed diagnosis remains common.

Cardiac Imaging AI & Automated Quantification (LLMs, Deep Learning, Reconstruction)

CineScribe: LLM-based detection and mitigation of ambiguity in cine cardiac magnetic resonance reports.

This study developed CineScribe, an LLM trained on expert-annotated cine cardiac MRI reports, to convert free-text cineCMR into structured regional wall-motion abnormality (RWMA) representations. CineScribe achieved a macro-F1 of 0.92 (95% CI 0.89–0.94) for the report-structuring task, enabling standardized report generation from validated diagnostic findings. Clinically, this could reduce ambiguity and inter-reader variability in cineCMR interpretation, improving downstream decision-making for left-ventricular wall-motion assessment.

Deep learning-based non-contrast cine CMR for optimized prediction of left ventricular adverse remodeling after ST-elevation myocardial infarction.

This retrospective, two-center study developed a non-contrast cine CMR deep learning (DL) model to predict left ventricular adverse remodeling (LVAR) after acute ST-elevation myocardial infarction (STEMI). Using 252 STEMI patients split into training (n=176) and testing (n=76) cohorts, the model employed a coarse-to-fine 3D U-shaped network for localization/segmentation and a classification model integrating imaging, morphological, and motion features. If validated, this approach could enable earlier, non-contrast risk stratification for post-MI remodeling to guide follow-up intensity and preventive therapies.

Robust Audio-Visual Question Answering with Missing Modality in Training and Testing.

The paper studied audio-visual question answering (AVQA) under modality-missing conditions by introducing Training-time Modality-Missing AVQA (TM-AVQA), where audio-missing and/or visual-missing samples can occur during both training and testing. It proposes a method to robustly answer questions despite missing modalities and demonstrates improved performance in the new missing-modality setting. This is significant for deploying AVQA systems in real-world scenarios with sensor failures or privacy-driven omission of visual data.

Physics-Informed Reconstruction of Transmural Myocardial Deformation from 3D Echocardiography: Validation Against Cardiac MRI.

This methodological validation study introduced a physics-informed reconstruction framework for transmural myocardial deformation from 3D echocardiography, aiming to estimate the full finite strain tensor across the myocardial wall. In a small cohort, the reconstructed transmural deformation metrics were validated against cardiac MRI. The approach is clinically relevant because it could enable more accurate, wall-wide assessment of myocardial mechanics using echocardiography rather than relying solely on CMR.

Artificial Intelligence in Cardiovascular Imaging and Risk Stratification: From Algorithmic Discovery to Meaningful Clinical Implication.

This review studied how artificial intelligence (AI)—including deep learning, foundation models, and multimodal integration—can be applied to cardiovascular imaging and risk stratification from algorithmic development to clinical impact. The key finding is that AI is shifting cardiovascular assessment toward automated, quantitative, patient-specific evaluation rather than operator-dependent interpretation and static population thresholds. The significance is that these advances could improve timeliness and precision of diagnosis and risk prediction, but require translation into meaningful clinical workflows.

Multimodality Imaging for Structural Heart Disease & Congenital Heart Disease

Myocardial remodeling and fibrosis by cardiovascular magnetic resonance in adults with congenital aortic valve stenosis.

This prospective CMR study assessed myocardial remodeling and fibrosis using cardiovascular magnetic resonance in adults with congenital aortic valve stenosis before and after aortic valve replacement (AVR). The key finding was that CMR could characterize structural left ventricular remodeling over time and identify CMR-associated markers linked to myocardial fibrosis in this congenital AS population. These data support CMR tissue and remodeling metrics as clinically relevant tools for risk assessment and monitoring after AVR in congenital aortic stenosis.

Multimodality Imaging of a Massive Intrapericardial Mediastinal Hemangioma: A Diagnostic Challenge.

This case studied the diagnostic work-up and surgical management of a massive intrapericardial mediastinal hemangioma in a 68-year-old man with a severe iodinated contrast allergy. An iodine-free multimodality strategy using 2’-deoxy-2’-[F-18]fluoro-D-glucose PET/CT, cardiac magnetic resonance, and contrast-enhanced ultrasound—guided by 3D reconstruction—enabled safe complete resection of an adventitial mixed hemangioma. The report highlights a practical imaging pathway when iodinated contrast is strictly contraindicated, improving diagnostic confidence and procedural safety for complex cardiac masses.

Arrhythmias, Sudden Cardiac Events & Device Planning

Guiding Pacemaker Implantation With Multimodality Imaging in an Adult With Ventricular Septal Defect.

This case studied multimodality imaging to guide pacemaker implantation in a 57-year-old adult with congenital ventricular septal defect and complete heart block. Multimodality imaging was used to plan lead positioning in the setting of complex septal anatomy, aiming to reduce procedural difficulty and improve safety. The clinical significance is that advanced preprocedural imaging can optimize device implantation strategies in adult congenital heart disease patients with atrioventricular block.

Membranous Interventricular Septal Aneurysm (MVSA) as a rare potential cause of embolic stroke: a case report and literature review.

This article studied membranous interventricular septal aneurysm (MVSA) as a rare cause of embolic stroke in a 42-year-old woman with recurrent cortical ischemic events. The key finding was that, after an exhaustive diagnostic work-up, no alternative embolic source was identified and MVSA was the only plausible etiology, supported by a literature review of similar cases. Scientifically, it reinforces MVSA as an underrecognized cardioembolic mechanism and can inform diagnostic evaluation of cryptogenic recurrent stroke.

Occult Idiopathic Ventricular Fibrillation After Preoperative Cardiovascular Evaluation.

This case report studied occult idiopathic ventricular fibrillation occurring after preoperative cardiovascular evaluation in a 50-year-old man undergoing elective surgery. Despite comprehensive testing—including coronary angiography, cardiac magnetic resonance, electrophysiological study, and genetic testing—no structural heart disease or inherited arrhythmia syndrome was found, and a dual-chamber implantable cardioverter-defibrillator was implanted after out-of-hospital cardiac arrest. Clinically, it underscores that “idiopathic” ventricular fibrillation can present abruptly even after clearance, supporting careful perioperative risk consideration and readiness for sudden arrhythmic events.

LGL-Phenocopy With Dual AV Nodal Physiology and Malignant SVT: A Diagnostic Pitfall With Sudden Deaths.

This JACC case report studied a 45-year-old man presenting with malignant supraventricular tachycardia and an ECG pattern resembling Lown-Ganong-Levine (short PR without preexcitation), including family history of sudden cardiac death. The key finding was that dual atrioventricular nodal physiology with malignant SVT substrates produced a diagnostic pitfall, with postconversion ECG showing short PR and dual AV nodal physiology rather than a benign LGL-phenocopy. The clinical significance is that it warns clinicians not to assume benignity of short-PR phenocopy patterns when malignant SVT and sudden death risk may be present.

Cardiomyopathies & Genetic/Variant-Driven Phenotypes

Takotsubo Syndrome: From Pathophysiology and Diagnosis to Management.

This article is a narrative review of Takotsubo syndrome (TTS), focusing on its pathophysiology, diagnosis, and management in patients who present with acute heart failure and transient left-ventricular dysfunction. It emphasizes that TTS typically occurs in postmenopausal women, often mimics acute myocardial infarction, and is characterized by regional wall-motion abnormalities extending beyond a single coronary territory without culprit coronary lesions. Scientifically and clinically, the review consolidates current mechanistic concepts (e.g., catecholamine-mediated cardiotoxicity and microvascular dysfunction) to support improved diagnostic differentiation and management strategies.

Longitudinal changes in cardiac function, volumes and fibrosis in a prospective cohort of female Duchenne and Becker muscular dystrophy carriers.

This prospective cohort study followed 75 genetically confirmed female Duchenne muscular dystrophy carriers and 22 non-carrier females with cardiac MRI at three annual visits to characterize longitudinal changes in ventricular volumes, function, and fibrosis. Using late-gadolinium enhancement (LGE), the study quantified fibrosis trajectories alongside functional and volumetric remodeling across follow-up timepoints. The results could clarify the natural history and cardiomyopathy risk in female dystrophin-mutation carriers, informing surveillance and potential early intervention strategies.

Multiple 4q25 risk variants impair calcium homeostasis and compromise left atrial function.

Using UK Biobank data from 391,008 individuals, this genetic association study tested how multiple 4q25 atrial fibrillation risk variants (rs1448818, rs2200733, rs10033464) affect calcium homeostasis and left atrial function. The three risk alleles increased incident atrial fibrillation in a dose-dependent manner, and genetic and clinical risk were additive for atrial fibrillation risk. Mechanistically, the work suggests SNP-specific effects on calcium handling that could inform targeted prevention or therapeutic strategies for atrial fibrillation.

Imaging signatures of high-risk arrhythmogenic genotypes in dilated cardiomyopathy.

This prospective study enrolled 90 patients with dilated cardiomyopathy (DCM) and stratified them into high-risk arrhythmogenic variant carriers (HRAv; DSP, FLNC, LMNA, PLN), TTN truncating variant carriers (TTNtv), and genotype-negative patients (GN), using comprehensive CMR parameters and logistic regression to link genotype to imaging phenotype. The key finding was that high-risk arrhythmogenic genotypes show distinct CMR imaging signatures compared with TTNtv and genotype-negative DCM, consistent with genotype–phenotype heterogeneity. Scientifically, this supports CMR as a noninvasive stratification tool for arrhythmia risk in genetically defined DCM subgroups.

Dilated Cardiomyopathy in a Woman With SPG4-Associated Hereditary Spastic Paraplegia.

This case studied dilated cardiomyopathy (DCM) in a 54-year-old woman with SPG4-associated hereditary spastic paraplegia (SPG4-HSP). Echocardiography and cardiac magnetic resonance showed nonischemic DCM with reduced ejection fraction and dyssynchrony, alternative causes were excluded, and extended cardiomyopathy gene testing was negative. The clinical significance is that SPG4-HSP may involve systemic cardiac pathology, warranting cardiac surveillance even when cardiomyopathy genes are not identified.

First Successful Cardiac Myosin Inhibitor Use for Donor-Derived HCM After Heart Transplant.

This case report studied donor-derived hypertrophic cardiomyopathy (HCM) in a 55-year-old woman after heart transplantation from a 30-year-old male donor who died suddenly. Despite calcium channel blocker and later beta-blocker therapy for severe dynamic left ventricular outflow tract obstruction, cardiac MRI confirmed donor-derived HCM and treatment with the cardiac myosin inhibitor mavacamten (Camzyos) was initiated. The report is clinically significant because it documents what is described as the first successful use of mavacamten for post-transplant donor-derived HCM, suggesting a targeted option when conventional rate/obstruction therapies fail.

Heart Failure Phenotyping, Risk Stratification & Prognosis

Imaging-Derived Sarcopenic Obesity and Cardiovascular Outcomes: Insights Into Heart Failure Risk and Muscle Biology.

This study examined whether imaging-derived sarcopenic obesity predicts cardiovascular outcomes and clarifies heart failure risk and muscle biology using a deep learning pipeline applied to cardiovascular imaging, integrated with long-term follow-up plus genomic and transcriptomic data. The key finding was that sarcopenic obesity—quantified from imaging—adds prognostic information beyond conventional obesity measures for heart failure risk, linking low muscle mass with adverse outcomes. Scientifically, it supports a more mechanistic, imaging-translatable phenotype of obesity that can be used for risk stratification and for connecting clinical outcomes to underlying genomic/transcriptomic signatures.

Coronary Artery Disease, Plaque Biology & Microvascular Dysfunction

Association between coronary high-intensity plaque and pericoronary adipose tissue attenuation and plaque morphology.

This retrospective study examined whether high-intensity plaque (HIP) on cardiac MRI is associated with pericoronary adipose tissue attenuation (PCATA) and coronary plaque morphology on CCTA in 86 patients with chronic coronary syndrome (104 lesions). HIP was defined on T1-weighted CMR as a plaque-to-myocardium signal intensity ratio (PMR) ≥ 1.4, and PCATA was quantified for the target lesion to relate imaging phenotypes to plaque burden and morphology. If the full results confirm the associations, HIP–PCATA coupling could provide a noninvasive imaging biomarker linking plaque composition and local adipose tissue characteristics to coronary risk.

Cardiac magnetic resonance in acute myocardial infarction undergoing thrombus aspiration.

This single-center observational cohort study evaluated the impact of clinically indicated thrombus aspiration (TA) during primary PCI on myocardial microvascular obstruction (MVO) and scar/remodeling in STEMI patients using cardiac MRI at baseline and 12 months. Patients undergoing primary PCI with or without TA were compared on CMR endpoints including MVO and myocardial scar characteristics over time. If TA shows differential effects on long-term remodeling, the findings could refine procedural decision-making in STEMI to better target MVO and adverse scar evolution.

Multiple manifestations of coronary microvascular dysfunction in a double-hit mouse model of HFpEF.

This preclinical study investigated multiple manifestations of coronary microvascular dysfunction (CMD) in a double-hit mouse model of HFpEF induced by high-fat diet plus chronic nitric oxide synthase inhibition (L-NAME) in C57BL/6 mice. Using a multimodal imaging platform—cine/strain cardiac MRI, dynamic contrast-enhanced MRI with galbumin and redox-sensitive 3CP contrast agents, and Doppler-based coronary flow reserve—along with ex vivo micro-CT angiography and transmission electron microscopy, the authors characterized distinct CMD phenotypes. The scientific significance is that it provides mechanism-resolved, non-invasive CMD phenotyping in HFpEF, supporting better translational targeting of microvascular mechanisms.

Cardiovascular Hemodynamics & Vascular Function (Stiffness, Flow, Compliance)

Whole heart non-contrast 4D Flow MRI at 3.0T for clinical follow-up of congenital heart disease in children and adolescents.

This prospective clinical study compared accelerated whole-heart 4D flow MRI (WH-4DF) at 3.0T with conventional 2D phase-contrast (2D-PC) and volumetric measurements for routine follow-up of surgically corrected pediatric congenital heart disease (CHD). Seventy-one consecutive children/adolescents (median age 14 years; 49 male) underwent both 2D-PC and WH-4DF MRI during follow-up, evaluating feasibility and clinical applicability. If WH-4DF demonstrates comparable accuracy with fewer plane/breath-hold constraints, it could streamline longitudinal hemodynamic assessment in pediatric CHD and reduce operator dependence.

CMR-based aortic stiffness parameters in a symptomatic high risk obstructive sleep apnea cohort: results from the population-based Hamburg City Health Study.

This population-based Hamburg City Health Study (HCHS) used CMR-derived aortic stiffness measures—pulse wave velocity (PWV) and 2D phase-contrast CMR aortic distensibility of the ascending and descending aorta—along with pulse pressure from blood pressure to assess associations with obstructive sleep apnea (OSA) in a symptomatic high-risk cohort. The study aimed to determine whether OSA status is linked to worse vascular aging markers as quantified by CMR aortic stiffness parameters. If confirmed, these CMR vascular biomarkers could improve risk stratification for OSA-related cardiovascular disease in community cohorts.

Correlation of seismocardiography variables with echocardiographic and cardiac magnetic resonance measurements.

This study evaluated correlations between seismocardiography (SCG) variables and systolic/diastolic measures from transthoracic echocardiography (TTE) and cardiac magnetic resonance (CMR) in 26 human participants (healthy and cardiovascular disease groups). The key finding was the degree to which SCG-derived mechanical vibration features align with established imaging markers of cardiac function across these populations. The significance is that wearable SCG could become a low-cost adjunct for cardiac function assessment if its imaging concordance is validated.

Cardiac Oncology & Metastasis/Malignancy Imaging

Prognostic value of different metabolic response criteria in patients with advanced melanoma treated with immunotherapy: a comparative analysis of PECRIT, PERCIMT, and EORTC criteria.

This retrospective comparative analysis evaluated advanced melanoma patients treated with immune checkpoint inhibitors (ICIs) who underwent baseline and interim [18F]FDG-PET/CT, comparing prognostic performance of metabolic response criteria PECRIT, PERCIMT, and EORTC. Metabolic response categories derived from these criteria (complete/partial/stable/progressive metabolic disease) showed differing prognostic stratification for patient outcomes. The findings help standardize how [18F]FDG-PET/CT metabolic response is interpreted during ICI therapy, which can improve risk assessment and treatment monitoring.

Osteosarcoma in a Young Patient: When the Tumor Reaches the Heart.

This case report studied cardiac metastasis from osteosarcoma in a 17-year-old boy whose tumor reached the heart. Echocardiography and cardiac magnetic resonance identified a mobile intracardiac mass attached to the tricuspid subvalvular apparatus with late gadolinium enhancement suggestive of malignancy, and histopathology confirmed metastatic osteosarcoma after surgical resection. The significance is that multimodality cardiac imaging can expedite recognition of rare metastatic disease and guide definitive surgical management in young patients with known osteosarcoma.

Radiation- and Therapy-Related Cardiac Complications

Radiation-Associated Mesothelioma With Mixed Constrictive-Restrictive Physiology After Mantle-Field Radiotherapy.

This case report studied radiation-associated mesothelioma presenting with mixed constrictive–restrictive physiology decades after mantle-field radiotherapy in a 60-year-old woman. Echocardiography and cardiac catheterization suggested constrictive physiology, while cardiac magnetic resonance was nondiagnostic and PET/CT demonstrated hypermetabolic pleural, mediastinal, and pericardial lesions consistent with malignancy. The clinical significance is that late thoracic radiation complications can produce complex cardiothoracic hemodynamics, and PET/CT may be crucial when conventional imaging is inconclusive.

Percutaneous and surgical left atrial appendage occlusion in non-valvular atrial fibrillation: Contemporary narrative review.

This contemporary narrative review synthesized evidence comparing surgical left atrial appendage occlusion (S-LAAO) and percutaneous left atrial appendage occlusion (pLAAO) for stroke prevention in non-valvular atrial fibrillation patients who cannot take oral anticoagulation. The review emphasized that direct comparative randomized evidence remains limited and evaluated procedural safety, thromboembolic outcomes, and imaging-confirmed completeness of left atrial appendage exclusion. The clinical significance is guidance for clinicians on selecting between surgical and percutaneous LAAO approaches based on the best available trial and imaging evidence.

Transcatheter atrial flow regulator implantation in children with pulmonary arterial hypertension in resource-limited settings: a single-centre experience.

This single-centre retrospective experience studied transcatheter atrial flow regulator implantation in children with World Health Organization Group 1 pulmonary arterial hypertension in resource-limited settings. The key finding was that implantation was feasible in six children with severe pediatric PAH where access to parenteral prostacyclin was constrained, aiming to provide right-heart decompression via a controlled interatrial shunt. The clinical significance is that it supports a potential alternative strategy for managing severe pediatric PAH when standard prostacyclin delivery is difficult to sustain.

Cardio-renal & Systemic Fibrotic/Multiorgan Links

Left Ventricular Mass is Associated with Biopsy-Assessed Renal Fibrosis in Chronic Kidney Disease.

This prospective single-center cohort study examined chronic kidney disease (CKD) patients with native kidneys who underwent same-week cardiac MRI and renal biopsy to test whether left ventricular (LV) remodeling on MRI is associated with biopsy-assessed renal interstitial fibrosis. LV mass (and related cardiac remodeling measures) was found to be associated with the percentage of renal cortical area affected by interstitial fibrosis. Clinically, linking cardiac MRI remodeling to direct renal histology supports integrated cardio-renal risk stratification and may help identify patients with more advanced systemic fibrotic disease.

Cardiovascular magnetic resonance reveals stable myocardial tissue characteristics despite cardiac remodelling after transjugular intrahepatic portosystemic shunt in liver cirrhosis.

This prospective study evaluated cardiac function, remodeling, and myocardial tissue characteristics by multiparametric cardiovascular magnetic resonance (CMR) in 23 adults with advanced liver cirrhosis undergoing transjugular intrahepatic portosystemic shunt (TIPS). Despite acute hemodynamic changes from TIPS, CMR showed stable myocardial tissue characteristics across follow-up (3–100 days) even as cardiac remodeling occurred. These findings suggest that TIPS-related cardiac remodeling in cirrhosis may not translate into measurable deterioration of myocardial tissue properties on CMR, supporting CMR as a tool to monitor cardiotoxicity risk in this setting.

Microbiome & Biomarkers in Cardiovascular Disease

Gut microbiota-derived imidazole propionate predicts cardiometabolic risk in patients with coronary artery disease.

This multicohort prognostic study measured gut microbiota-derived imidazole propionate (ImP) in independent prospective cohorts of patients with acute coronary syndrome (ACS) and chronic coronary syndrome (CCS) to determine whether circulating ImP predicts cardiometabolic risk. Higher circulating ImP levels were associated with worse cardiometabolic outcomes across the CAD cohorts. This supports ImP as a microbiome-derived biomarker that may help refine risk prediction in coronary artery disease.

Translational/Preclinical Mechanisms & Therapeutic Targets (non-imaging)

Formoterol fumarate attenuates atherosclerosis and improves cardiometabolic dysfunction in ApoE-deficient mice.

This preclinical study tested formoterol fumarate, a long-acting β2-adrenergic receptor agonist, in 8-week-old male ApoE-deficient (ApoE KO) mice to assess effects on atherosclerosis and cardiometabolic dysfunction. Formoterol treatment (0.1 or 0.3 mg/kg/day for 8 weeks) was evaluated using serum lipid profiling, liver/heart damage biomarkers, and vascular imaging including en face Oil Red O staining. The findings, if supported by the full data, suggest a potential anti-atherosclerotic and multi-organ metabolic benefit of β2-agonist therapy in an ApoE KO model relevant to human cardiometabolic disease.

Targeted KRASG12V Degradation In Vivo Elicits Lung Adenocarcinoma Regression with Subsequent Relapse from Dysregulated Proteolysis.

This preclinical study developed an in vivo lung adenocarcinoma mouse model to test targeted degradation of KRASG12V using a proteolysis-targeting chimera (PROTAC) approach. Targeted KRASG12V degradation induced rapid tumor regression via cancer cell-autonomous mechanisms but was followed by relapse associated with dysregulated proteolysis. The results provide mechanistic insight into how KRAS degradation can drive initial response yet still permit resistance, informing next-generation KRAS-targeting degraders.

Cardiac safety of chronic inhibition of the myostatin-activin pathway with bimagrumab in healthy older adults.

In a randomized, double-blind, placebo-controlled trial, 68 healthy community-living adults aged 60–86 years received 6 months of chronic inhibition of the myostatin–activin pathway with bimagrumab (vs placebo) to assess cardiac safety and cardiovascular parameters. The key finding was the absence of clinically concerning cardiac safety signals over treatment and follow-up (up to 6 months), indicating tolerability of long-term pathway inhibition in older adults. This supports the cardiovascular safety of bimagrumab in humans and informs risk-benefit considerations for therapies targeting muscle and fat remodeling.

Reperfusion Injury and Infarct Size: Why Translation has Been Difficult, and How We Move Forward.

This review article analyzed why reperfusion injury cardioprotection has been difficult to translate into clinical benefit in reperfused ST-elevation myocardial infarction (STEMI) and proposed a framework for future trials. It highlighted that multiple contemporary cardioprotection trials in enriched STEMI cohorts were largely neutral for CMR infarct size endpoints (e.g., STEMI-DTU, PiCSO-AMI-I, EURO-ICE, COOL AMI EU). The significance is a roadmap for designing next-generation cardioprotection studies that better account for the network of interrelated injury pathways and improve the likelihood of clinically actionable outcomes.

Vitronectin-driven amyloid deposition disrupts mitochondrial homeostasis via integrin-mediated pathway in a humanized mouse model of transthyretin cardiac amyloidosis.

This preclinical study investigated vitronectin (VTN)-driven amyloid deposition mechanisms in a humanized mouse model of transthyretin cardiac amyloidosis using knock-in mice expressing wild-type TTR (hTTRWT) or the V142I mutant (hTTRV142I). The key finding was that VTN-associated amyloid deposition disrupted mitochondrial homeostasis through an integrin-mediated pathway, accompanied by measurable changes in amyloid burden and cardiac structure/function. Scientifically, it identifies a mechanistic link between extracellular matrix components and mitochondrial dysfunction in ATTR-CM, suggesting potential integrin-targeted therapeutic strategies.

[Clinical study of brentuximab vedotin combined with the ifosfamide and gemcitabine regimen in the treatment of children with relapsed or refractory classic Hodgkin lymphoma].

This case series studied brentuximab vedotin combined with the ifosfamide–gemcitabine (IGE) regimen in 23 children with relapsed or refractory classic Hodgkin lymphoma treated at Beijing Children’s Hospital between June 2022 and August 2025. The abstract reports that all enrolled children received 1–4 cycles of BV+IGE, with efficacy and safety outcomes assessed through follow-up to December 31, 2025. If confirmed in the full results, BV+IGE could represent a clinically actionable consolidation/chemo-sparing strategy for pediatric relapsed/refractory cHL, pending detailed response rates, survival, and toxicity profiles.

The combination of alternating reduced-dose blinatumomab and hyper-CVAD as consolidation therapy in patients with newly-diagnosed adult B-cell acute lymphoblastic leukemia.

This retrospective study assessed whether combining reduced-dose blinatumomab with hyper-CVAD improves outcomes in newly diagnosed adult B-cell acute lymphoblastic leukemia (B-ALL) patients who achieved complete remission after induction. Patients received consolidation with alternating blinatumomab cycles (cycles 1, 3, 5, and 7) and hyper-CVAD course A/B chemotherapy (course B for cycles 2 and 6; course A for cycles 4 and 8), stratified by Philadelphia chromosome (Ph)-positive versus Ph-negative status. If the full results show improved survival or MRD clearance, this regimen could offer a practical consolidation strategy integrating targeted bispecific therapy with chemotherapy in adult B-ALL.

Modified natural cycle versus hormone replacement therapy embryo transfer in women over 40 years old: a retrospective analysis.

This retrospective multicenter cohort study compared modified natural cycle embryo transfer (mNC-ET) versus hormone replacement therapy embryo transfer (HRT-ET) in women aged ≥40 years undergoing single embryo transfer (SET), analyzing 26,039 SETs from 16,579 women across 21 clinics in Spain and Italy. The key finding was the relative difference in live birth rate and other reproductive outcomes between the two endometrial preparation protocols in this older population. Clinically, the results inform protocol selection for endometrial preparation in women ≥40 to optimize live birth chances while considering cycle characteristics and outcomes.

Development and evaluation of a Raman detector for non-destructive identification and quantitation of cytostatic drugs in different primary packaging containers.

This study developed and evaluated a dedicated Raman detector for non-destructive identification and quantitation of cytostatic drugs directly through sealed primary packaging containers. Using Raman spectroscopy, the detector measured cyclophosphamide and gemcitabine in clinically relevant aqueous concentrations (1–45 mg/mL) in closed infusion glass, enabling direct concentration assessment without opening containers. The scientific/clinical significance is improved quality assurance for personalized chemotherapy by enabling rapid, non-invasive verification of cytostatic drug identity and concentration in pharmacy workflows.
