Summary: A.-E. C. M. O. with or without Left Ventricular Active Unloading. Veno-arterial extracorporeal membrane oxygenation (V. A.-E. C. M. O.), commonly used in refractory cardiogenic shock, is known to exacerbate left ventricular loading conditions and impair cardiac energetics. Adjunctive left ventricular unloading strategies are frequently combined with V. A.-E. C. M. O. to counteract these negative effects. These strategies, including intra-aortic balloon pump (I. A. B. P.) or Impella, aim to enhance myocardial recovery through activation of cardioprotective pathways. This approach directly addresses the recognized myocardial strain induced by V. A.-E. C. M. O.

Journal: Heart (British Cardiac Society)

Summary: Current heart failure guidelines advocate for hemodynamic assessment based on four clinical profiles: dry-warm, wet-warm, dry-cold, and wet-cold. However, evaluation of perfusion status often receives less attention due to a recognized absence of simple and reliable physical indicators. This study focused on the perfusion index, a noninvasive parameter derived from the ratio of pulsatile to non-pulsatile blood flow, as a potential marker for detecting hypoperfusion in heart failure patients. It addressed a crucial diagnostic gap in routine clinical assessment.

Single-cell sequencing of systemic sirtuin 1 heterozygous knockout mice revealed abnormal activation of trophoblast retinoic acid receptor responder 2 (RARRES2) and macrophage chemokine-like receptor 1 (CMKLR1) at the maternal-fetal interface. The investigation determined that low sirtuin 1 in trophoblasts increases retinoic acid receptor responder 2 expression, which subsequently affects macrophage polarization. This mechanism clarifies a key pathway in preeclampsia pathogenesis.

Summary: A pulmonary hypertension (P. H.)-related circular R. N. A., circMFN2, originating from the mitofusin-2 (MFN2) locus, was identified. This circMFN2 was significantly downregulated in the peripheral blood of patients with P. H. and in the pulmonary arteries of Sugen/hypoxia-induced P. H. mice. The study demonstrated that circMFN2 regulates the insulin-like growth factor two messenger R. N. A. binding protein three (IGF2BP3)-pyruvate dehydrogenase kinase four (PDK4) pathway. This regulation by circMFN2 ameliorates P. H., indicating its role as a potential therapeutic target.

Today’s date is February 08, 2026. Welcome to Cardiology Today. Here are the latest research findings.

Article number one. Coronary Artery Compliance Modification after Non-Compliant Balloon Angioplasty and Intravascular Lithotripsy. Intravascular lithotripsy demonstrates efficacy in treating balloon-crossable calcified coronary lesions. It achieves this by inducing calcium fractures and improving coronary artery compliance. This study evaluates patients with calcified coronary artery lesions from the BENELUX-IVL prospective registry who received intravascular lithotripsy under intravascular ultrasound. The research provides a direct comparison of coronary artery compliance modification between intravascular lithotripsy and non-compliant balloon angioplasty.

Article number two. Outcomes of High-Risk Pulmonary Embolism Stratified by Clinical Phenotype: Results from Two Specialized Pulmonary Embolism Centres. High-risk pulmonary embolism presents with high early mortality and a heterogeneous patient population, ranging from cardiac arrest to obstructive shock or hypotension. Systemic thrombolysis remains the standard of care, but its use is limited by contraindications and bleeding risk. Catheter-directed therapies offer alternatives, though data on their use in high-risk pulmonary embolism is limited. This study characterized the clinical characteristics, management strategies, and outcomes across three distinct high-risk pulmonary embolism clinical phenotypes.

Article number three. Small extracellular vesicle-mediated adipocyte-cardiomyocyte crosstalk exacerbates heart failure with preserved ejection fraction. Heart failure with preserved ejection fraction (H. F. pEF) phenotypes were induced in male C57BL/6N mice using a high-fat diet combined with Nω-nitro-l-arginine methyl ester. The study found a causal relationship between adiposity and Heart Failure with Preserved Ejection Fraction pathogenesis. Resection of visceral adipose tissue blunted Heart Failure with Preserved Ejection Fraction phenotypes in mice, while transplantation of visceral adipose tissue exacerbated these phenotypes.

Article number four. SIRT1-NCOR2 Corepressor Modulates Trophoblast-Macrophage Interactions in Preeclampsia. Preeclampsia, a severe hypertensive disorder of pregnancy, is associated with low sirtuin 1 (SIRT1) levels in trophoblasts. Single-cell sequencing of systemic sirtuin 1 heterozygous knockout mice revealed abnormal activation of trophoblast retinoic acid receptor responder 2 (RARRES2) and macrophage chemokine-like receptor 1 (CMKLR1) at the maternal-fetal interface. The investigation determined that low sirtuin 1 in trophoblasts increases retinoic acid receptor responder 2 expression, which subsequently affects macrophage polarization. This mechanism clarifies a key pathway in preeclampsia pathogenesis.

Article number five. circMFN2 Regulates the IGF2BP3-PDK4 to Ameliorate Pulmonary Hypertension. A pulmonary hypertension (P. H.)-related circular R. N. A., circMFN2, originating from the mitofusin-2 (MFN2) locus, was identified. This circMFN2 was significantly downregulated in the peripheral blood of patients with P. H. and in the pulmonary arteries of Sugen/hypoxia-induced P. H. mice. The study demonstrated that circMFN2 regulates the insulin-like growth factor two messenger R. N. A. binding protein three (IGF2BP3)-pyruvate dehydrogenase kinase four (PDK4) pathway. This regulation by circMFN2 ameliorates P. H., indicating its role as a potential therapeutic target.

The study emphasized the importance of equitable and accurately calibrated risk prediction tools for diverse young adult populations.

Article number two. 1-Year Outcomes of Novel Balloon-Expandable vs Contemporary Transcatheter Heart Valves in Severe Aortic Stenosis: The LANDMARK Trial. The LANDMARK trial found that the Myval balloon-expandable Transcatheter Heart Valve (T. H. V.) series was noninferior to the most commonly used contemporary SAPIEN and Evolut Series T. H. V.s for the 30-day early safety endpoint. This finding was observed in participants with symptomatic severe native aortic stenosis. The study thereby established the initial safety profile of the novel Myval valve in comparison to established devices. Further evaluation of its one year clinical outcomes, hemodynamic performances, and quality of life is ongoing.

Article number three. Left Ventricular Health and TAVR Timing in Asymptomatic Severe Aortic Stenosis: Analysis From the EARLY TAVR Trial. The EARLY TAVR trial definitively demonstrated that early Transcatheter Aortic Valve Replacement (TAVR) was superior to clinical surveillance for patients with asymptomatic severe aortic stenosis. This finding revealed a clear benefit of early intervention in improving patient outcomes. The subsequent analysis examined how baseline Left Ventricular (L. V.) health impacted this treatment effect and observed longitudinal L. V. health under different treatment strategies. These observations underscore the critical role of L. V. function in optimizing management decisions for asymptomatic severe aortic stenosis.

Article number four. Heart failure in the Portuguese population aged ≥50 years: prevalence and phenotypes in the PORTHOS study. Heart failure constitutes a significant global health burden, with its true prevalence often uncertain due to heterogeneous study designs and evolving diagnostic criteria. The Portuguese Heart Failure Prevalence Observational Study (PORTHOS) investigated the prevalence and phenotypic distribution of heart failure in community-dwelling adults aged 50 years and older in mainland Portugal. This cross-sectional, population-based study provided a detailed epidemiological snapshot of heart failure within this specific European demographic. The findings from PORTHOS are essential for understanding regional disease burden and informing public health strategies.

Article number five. Subvalvular aortic stenosis in adults: clinical course and long-term outcomes. This study delineated the clinical course and long-term outcomes for adults diagnosed with subvalvular aortic stenosis, utilizing prospectively registered data from the Dutch Congenital Cor Vitia registry. Researchers comprehensively assessed all-cause mortality, subvalvular aortic stenosis re-operation rates, and significant cardiovascular events, including arrhythmias and heart failure. The investigation also tracked longitudinal changes in echocardiographic peak velocity and interventricular septal thickness. Patients received an extensive follow-up period averaging 17.1 years, providing robust data on disease progression and long-term management challenges.

Summary: The abstract reports that several observational studies supported conscious sedation for endovascular thrombectomy in acute ischemic stroke and associated general anesthesia with poor functional outcomes. Conversely, recent randomized controlled trials have shown no difference in functional outcomes between general anesthesia and conscious sedation. This highlights a critical ongoing debate regarding the optimal anesthesia choice for mechanical thrombectomy in patients with acute ischemic stroke. The abstract’s context emphasizes the importance of understanding the definitive impact of anesthesia type on patient functional recovery.

Summary: This study integrated paired radiomics and transcriptomics from 32 ischemic stroke clots retrieved by mechanical thrombectomy. The analysis identified neutrophil extracellular trap enrichment within these clots as a predictor of first-pass mechanical thrombectomy success. Results demonstrated the potential for noninvasively detecting neutrophil extracellular trap enrichment using prethrombectomy computed tomography imaging. This represents a significant advancement for predicting successful clot removal and refining treatment approaches in acute ischemic stroke.

Summary: The abstract establishes that stroke is a sexually dimorphic disease, demonstrating differences in risk factors, incidence, outcomes, and treatment responses between men and women. It highlights that previous preclinical studies supporting these sex differences often originated from single-site studies with small sample sizes. Therefore, validating these variations across diverse research settings, as intended by the S. P. A. N. (Stroke Preclinical Assessment Network) trial, holds significant clinical importance. Understanding these inherent sex-based differences is crucial for developing more targeted and effective stroke management strategies.

Summary: Cancer survivors undergoing heart transplantation demonstrated an increased incidence of de novo malignancies when compared with malignancy recurrences. For select cancer survivors who develop advanced heart failure, heart transplantation remains the gold standard treatment. This finding underscores a significant long-term concern in this specific patient population. Understanding the distinct patterns of subsequent primary cancers is crucial for developing optimized post-transplant surveillance and management strategies.

Summary: This randomized controlled trial in 168 patients with stable coronary artery disease demonstrated that acute vigorous exercise and a 12-week high-intensity interval training program affect systemic inflammatory biomarkers. The research confirmed the role of persistent low-grade inflammation in coronary artery disease progression. These findings provide critical evidence for developing exercise-based interventions aimed at modulating systemic inflammation in patients with stable coronary artery disease. The study contributes to understanding how specific exercise regimens influence the inflammatory profile in this patient population.
