Prognosis and Management of Recurrent Stenosis After Pulmonary Vein Stenting: A Prospective Study.

Background: Pulmonary vein stenting is effective for severe pulmonary vein stenosis, which is limited by restenosis. The assessment and management of in-stent restenosis (ISR) are inadequate, and follow-up outcomes after reintervention remain unknown.

Objectives: This study aimed to assess the prognosis and management of pulmonary vein ISR and determine whether the modified stent-in-stent strategy is superior to balloon angioplasty (BA) in treating ISR.

Targeting cardiac fibrosis with Chimeric Antigen Receptor-Engineered Cells.

Cardiac fibrosis poses a significant challenge in cardiovascular diseases due to its intricate pathogenesis, and there is currently no standardized and effective treatment approach. The fibrotic process entails the involvement of various cell types and molecular mechanisms, such as fibroblast activation and proliferation, increased collagen synthesis, and extracellular matrix rearrangement. Traditional therapies often fall short in efficacy or carry substantial side effects.

Meta-lasso: new insight on infection prediction after minimally invasive surgery.

Surgical site infection (SSI) after minimally invasive lung cancer surgery constitutes an important factor influencing the direct and indirect economic implications, patient prognosis, and the 5-year survival rate for early-stage lung cancer patients. In the realm of predictive healthcare, machine learning algorithms have been instrumental in anticipating various surgical outcomes, including SSI. However, accurately predicting infection after minimally invasive surgery remains a clinical challenge due to the multitude of physiological and surgical factors associated with it.

Reporter Molecules Embedded Au@Ag Core-Shell Nanospheres as SERS Nanotags for Cardiac Troponin I Detection.

Rapid and accurate detection of acute myocardial infarction can improve patients' chances of survival. Cardiac troponin I (cTn I) is an important diagnostic biomarker for acute myocardial infarction. However, current immunoassays are insufficient to accurately measure cTn I, as they have limited detection sensitivity and are time-consuming.

Thrombus-specific/responsive biomimetic nanomedicine for spatiotemporal thrombolysis and alleviation of myocardial ischemia/reperfusion injury.

Acute myocardial infarction (AMI) is usually caused by coronary thrombosis. However, the short half-life, lack of targetability and inevitable ischemia/reperfusion injury secondary to revascularization, which characterizes tissue plasminogen activator (tPA) limit its thrombolytic efficacy for AMI. To address the targeted and site-specific delivery of tPA, the current study reports the construction of a thrombus-targeting and responsive biomimetic nanoparticle (PTPN) for spatiotemporal treatment of AMI.

Development of a Nomogram for Predicting Surgical Site Infection in Patients with Resected Lung Neoplasm Undergoing Minimally Invasive Surgery.

Predictive models are necessary to target high-risk populations and provide precision interventions for patients with lung neoplasm who suffer from surgical site infections (SSI). This case control study included patients with lung neoplasm who underwent minimally invasive surgeries (MIS). Logistic regression was used to generate the prediction model of SSI, and a nomogram was created.

Polydopamine stabilizes silver nanoparticles as a SERS substrate for efficient detection of myocardial infarction.

Rapid and accurate detection of myocardial infarction (MI) can boost the patient's chance of survival. Surface enhanced Raman scattering (SERS) is an outstanding diagnostic technique because of its strong light stability, high resolution, and qualitative and quantitative analysis based on the characteristic fingerprint. However, its reliability, stability and specificity remain to be improved, especially in the quantitative analysis of serum samples.

Circular RNA hsa_circ_0008896 accelerates atherosclerosis by promoting the proliferation, migration and invasion of vascular smooth muscle cells via hsa-miR-633/CDC20B (cell division cycle 20B) axis.

Circular RNAs, a class of circularly closed non-coding RNAs, play essential roles in the formation of atherosclerosis, which is a frequent cause of cardiovascular and cerebrovascular diseases. Although many circular RNAs are found to be involved in the progression of atherosclerosis, more circular RNA regulators still need to be identified, to improve the understanding of the regulatory networks of atherosclerosis. Here, we found that hsa_circ_0008896 was significantly up-regulated in both and atherosclerosis models, indicating hsa_circ_0008896 was involved in the progression of atherosclerosis.

Engineered Biomimetic Nanoplatform Protects the Myocardium Against Ischemia/Reperfusion Injury by Inhibiting Pyroptosis.

Protection of cardiomyocytes against oxidative stress is vital to alleviate myocardial ischemia/reperfusion injury (MI/RI). However, antioxidative treatment is hampered by the lack of safe and effective therapeutics. Polydopamine (PDA), as a biodegradable class of nanomaterial with excellent antioxidant properties, has shown great potential in treating MI/RI.

Relationship between thromboelastography and long-term ischemic events as gauged by the response to clopidogrel in patients undergoing elective percutaneous coronary intervention.

Ischemic events after percutaneous coronary intervention (PCI) remain a major concern for patients with coronary heart disease (CHD). The aim of the current study was to investigate whether thromboelastography (TEG) was a satisfactory technique to measure platelet function in vitro in order to improve risk stratification and the individual response to antiplatelet therapy. The diagnostic and prognostic utility of the maximum amplitude of adenosine diphosphate induced platelet-fibrin clots (MAADP) was measured with TEG in 759 patients undergoing elective PCI.

CASZ1 loss-of-function mutation contributes to familial dilated cardiomyopathy.

Background: The zinc finger transcription factor CASZ1 plays a key role in cardiac development and postnatal adaptation, and in mice, deletion of the CASZ1 gene leads to dilated cardiomyopathy (DCM). However, in humans whether genetically defective CASZ1 contributes to DCM remains unclear.

Methods: The coding exons and splicing junction sites of the CASZ1 gene were sequenced in 138 unrelated patients with idiopathic DCM.

TBX5 loss-of-function mutation contributes to atrial fibrillation and atypical Holt-Oram syndrome.

Previous genome-wide association studies have demonstrated that single nucleotide polymorphisms in T‑box (TBX)5 are associated with increased susceptibility to atrial fibrillation (AF), and a recent study has causally linked a TBX5 mutation to atypical Holt-Oram syndrome and paroxysmal AF. However, the prevalence and spectrum of TBX5 mutations in patients with AF remain to be elucidated. In the present study, a cohort of 190 unrelated patients with idiopathic AF were prospectively recruited, with 400 unrelated healthy individuals recruited as controls.

A HAND2 Loss-of-Function Mutation Causes Familial Ventricular Septal Defect and Pulmonary Stenosis.

Congenital heart disease (CHD) is the most common developmental abnormality, and is the leading noninfectious cause of mortality in neonates. Increasing evidence demonstrates that genetic defects play an important role in the pathogenesis of CHD. However, CHD exhibits substantial heterogeneity, and the genetic determinants for CHD remain unknown in the overwhelming majority of cases.
