Effect of heart rate on B-type natriuretic peptide in sinus rhythm.

Sci Rep

December 2024

Division of Cardiology, Department of Internal Medicine, The Jikei University School of Medicine, 3-25-8 Nishi-shimbashi, Minato-ku, Tokyo, 105-8461, Japan.

B-type natriuretic peptide (BNP) levels accurately reflect the degree of cardiac overload in heart failure. Considering cardiac morphology and intracardiac pressure, including the left ventricular end-systolic volume index (LVESVI) and left ventricular end-diastolic volume index (LVEDVI), is essential for cardiac overload assessment. These indexes influence plasma BNP levels, and high heart rate is likely associated with cardiac morphology.

Triglyceride to high density lipoprotein cholesterol ratio and major adverse cardiovascular events in ACS patients undergoing PCI.

Sci Rep

December 2024

State Key Laboratory of Frigid Zone Cardiovascular Disease, Cardiovascular Research Institute, Department of Cardiology, General Hospital of Northern Theater Command, Shenyang, 110016, China.

The triglyceride to high density lipoprotein cholesterol (TG/HDL-C) ratio has been consistently linked with the risk of coronary heart disease (CHD). Nevertheless, there is a paucity of studies focusing on acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI) or experiencing bleeding events. The study encompassed 17,643 ACS participants who underwent PCI.

Differential effects of fine particulate matter constituents on acute coronary syndrome onset.

Nat Commun

December 2024

School of Public Health, Key Lab of Public Health Safety of the Ministry of Education, Fudan University, Shanghai, China.

Fine particulate matter has been linked with acute coronary syndrome. Nevertheless, the key constituents remain unclear. Here, we conduct a nationwide case-crossover study in China during 2015-2021 to quantify the associations between fine particulate matter constituents (organic matter, black carbon, nitrate, sulfate, and ammonium) and acute coronary syndrome, and to identify the critical contributors.

Objective: Inflammation and oxidative damage play critical roles in the pathogenesis of sepsis-induced cardiac dysfunction. Multiple EGF-like domains 9 (MEGF9) is essential for cell homeostasis; however, its role and mechanism in sepsis-induced cardiac injury and impairment remain unclear.

Methods: Adenoviral and adeno-associated viral vectors were applied to overexpress or knock down the expression of MEGF9 in vivo and in vitro.

The β-1,4 galactosylation catalyzed by β-1,4 galactosyltransferases (β4Gal-Ts) is not only closely associated with diverse physiological and pathological processes in humans but also widely applied in the -glycan modification of protein glycoengineering. The loop-closing process of β4Gal-Ts is an essential intermediate step intervening in the binding events of donor substrate (UDP-Gal/Mn) and acceptor substrate during its catalytic cycle, with a significant impact on the galactosylation activities. However, the molecular mechanisms in regulating loop-closing dynamics are not entirely clear.

Moyamoya disease (MMD) is a progressive cerebrovascular disorder that increases the risk of intracranial ischemia and hemorrhage. Timely diagnosis and intervention can significantly reduce the risk of new-onset stroke in patients with MMD. However, the current diagnostic methods are invasive and expensive, and non-invasive diagnosis using biomarkers of MMD is rarely reported.

Template-Assisted Electrospinning and 3D Printing of Multilayered Hierarchical Vascular Grafts.

J Biomed Mater Res B Appl Biomater

January 2025

Department of Polymer and Biomaterials Science, Faculty of Chemical Technology and Engineering, West Pomeranian University of Technology in Szczecin, Szczecin, Poland.

Fabricating complex hierarchical structures mimicking natural vessels and arteries is pivotal for addressing problems of cardiovascular diseases. Various fabrication strategies have been explored to achieve this goal, each contributing unique advantages and challenges to the development of functional vascular grafts. In this study, a three-layered tubular structure resembling vascular grafts was fabricated using biocompatible and biodegradable copolymers of poly(butylene succinate) (PBS) using advanced manufacturing techniques.

We present a case of a 72-year-old female patient with dyspnea and lipothymia. Echocardiography demonstrates an intracavitary cystic mass that fills almost all left atria causing supravalvular obstruction. The magnetic resonance image revealed a 53 × 47 × 48 mm heterogeneous mass with regular edges, tissue characterization suggested myxoma.

A 43-year-old woman presented with dyspnea and cough, initially misdiagnosed as respiratory syncytial virus. Persistent symptoms led to pulmonary thromboembolism treatment, but worsening issues revealed recurrent pericardial effusion. Imaging and biopsy confirmed pulmonary artery intimal sarcoma, mimicking thromboembolism, and autoimmune disease, underscoring diagnostic challenges.

Background: The new Amplatzer Steerable Delivery Sheath is a delivery system designed to improve ease-of-use and procedural results of left atrial appendage closure (LAAC). We aimed to compare procedural results after switching our LAAC program at a tertiary care center with the Amulet device to the Steerable Delivery Sheath, with a control group of LAAC employing the standard sheath.

Methods: The first n = 32 consecutively treated patients at our site using the Amulet device with the Steerable Delivery Sheath were included in this retrospective analysis.

The pulmonary valve (PV), although often less emphasized than other heart valves, is crucial for cardiac function and hemodynamics. Historically, the PV has been underrepresented in echocardiographic assessments due to its rare involvement in pathological conditions, particularly in adults. Additionally, the anatomical position of the PV makes it one of the most challenging valves to visualize using conventional echocardiography.

Cardiogenic shock in women: From risk factors to therapy.

Kardiol Pol

December 2024

Department of Cardiology, Rigshospitalet, Copenhagen, Denmark.

Cardiogenic shock (CS) in women is a serious cardiovascular (CV) event associated with a high mortality rate. Non-ischemic etiologies are the most common etiologies in women, such as stress-induced cardiomyopathy, peripartum/postpartum cardiomyopathy, heart failure-related CS, or CS due to myocarditis or valvular heart disease. Although not being the most common etiology in women, acute myocardial infarction is still an important one.

Clinical Rationale For Study: We have reported that intracerebral haemorrhage (ICH) of unknown cause at a young age is associated with lower prothrombin and factor VII and higher antithrombin activity, along with the formation of looser fibrin networks displaying enhanced lysability. Patients with mild-to-moderate bleeding of unknown cause have elevated levels of free plasma tissue factor pathway inhibitor alpha (fTFPIα), inhibiting the tissue factor-factor VII complex and prothrombinase.

Aim Of Study: We hypothesised that patients with an intracerebral haemorrhage (ICH) of unknown cause may also exhibit higher fTFPIα.

Background: Despite advancements in valve implantation devices, vascular access complications (VAC) remain a significant cause of morbidity and mortality for those undergoing transcatheter aortic valve replacement (TAVR). We describe pre-operative imaging analysis of the aortoiliac and femoral arterial beds using the TransAtlantic intersociety consensus (TASC) score, ilio-femoral tortuosity, and procedural characteristics to identify anatomic risk factors predictive of VAC in TAVR.

Methods: Consecutive patients undergoing TAVR from 2012 to 2022 at a single North Dakota hospital were retrospectively reviewed.

Delirium is a neuropsychiatric syndrome commonly presenting during acute illness. The pathophysiology of delirium is unknown, but neuroinflammation is suggested to play a role. In this cross-sectional study, we aimed to investigate whether cell-free DNA and markers of neutrophil extracellular traps in serum and CSF were associated with delirium and neuronal damage, assessed by neurofilament light chain.
