Background and Aims: Although combined general anesthesia and epidural analgesia are used in open surgery to promote rehabilitation and expectoration, as well as to prevent postoperative pulmonary complications, their effect in thoracoscopic esophagectomy remains unclear. This study aimed to address this issue. Patients and Methods: We enrolled 150 patients who underwent thoracoscopic esophagectomy between May 2017 and July 2025. Patient characteristics and postoperative outcomes, including maximum numerical rating scale (NRS) after surgery and pneumonia, were compared between the use and non-use of epidural analgesia. Epidural analgesia was not administered in patients using antithrombotic/anticoagulant drugs or in those with a history of thoracic spine surgery. Postoperative analgesia involved the scheduled administration of acetaminophen in all cases, with patient-controlled analgesia using opioids administered to the non-epidural analgesia group. Results: Epidural analgesia was administered to 113 patients (75.3%). The most common levels of epidural catheter placement were Th8/Th9 in 55 patients (36.7%) and Th7/Th8 in 41 patients (27.3%). Laparoscopy was performed in 129 patients (86.0%). Median NRS was five, and pneumonia occurred in 16 patients (10.7%). The epidural anesthesia group had a higher proportion of squamous cell carcinoma (88.5% vs. 73.0%, p = 0.024), lower lymphocyte counts (1680 vs. 2065, p = 0.020), diabetes (16.8% vs. 37.8%, p = 0.007), and hypertension (54.9% vs. 81.1%, p = 0.006), and circular stapler anastomosis (83.2% vs. 62.2%, p < 0.001). No significant differences were observed in the postoperative NRS, pneumonia, or length of postoperative hospital stay. Conclusions: There was no significant difference in the postoperative NRS and pneumonia between those with or without epidural analgesia in thoracoscopic esophagectomy. Full article

Background: Acute coronary syndromes (ACSs) remain a leading cause of death and disability. Since the publication of the 2023 ESC ACS guidelines, multiple studies and an ESC/EAS dyslipidaemia update have refined how clinicians diagnose, revascularize, and treat ACS across the care continuum. Content: This state-of-the-art review synthesizes advances from 2023 to 2025 across five domains. Diagnosis: High-sensitivity troponin-based accelerated pathways remain foundational; GRACE 3.0 improves calibration for early vs. delayed angiography, while selective use of CCTA and routine use of intracoronary imaging/physiology help define the mechanism and optimize PCI. Revascularization: complete revascularization continues to underpin care in multivessel disease, with recent data favouring culprit-only PCI acutely and staged non-culprit treatment during the index stay in most STEMI presentations, particularly with heart-failure physiology. Antithrombotic therapy: Aspirin remains critical early after ACS-PCI; emerging evidence supports shorter DAPT and aspirin withdrawal after 1 month in carefully selected, low-ischaemic-risk patients, whereas day-0 aspirin-free strategies in unselected ACS are not non-inferior. Secondary prevention: A “strike early and strong” approach to LDL-cholesterol—often with combination therapy in hospital—is emphasized, alongside nuanced roles for SGLT2 inhibitors and GLP-1 receptor agonists. Special populations and implementation: Sex- and age-aware tailoring (including MINOCA/SCAD evaluation), pragmatic bleeding-risk mitigation, digitally enabled cardiac rehabilitation, and registry-driven quality improvement translate evidence into practice. Summary: Contemporary ACS care is moving from uniform protocols toward risk-stratified, mechanism-informed pathways. We offer practical algorithms and checklists to align interventional timing, antithrombotic intensity/duration, and secondary prevention with individual patient risk—bridging new evidence to bedside decisions.

(1) Background: Whether anticoagulation can be resumed in atrial fibrillation (AF) combined with intracranial hemorrhage (ICH), and which anticoagulation modality is used with better efficacy and safety, is unknown. (2) Method: Randomized controlled trials (RCTs) and observational studies on relevant topics were included by searching five databases: PubMed, EMBASE, EBSCO, Cochrane Central Register of Controlled Trial and ClinicalTrials. Bayesian network meta-analysis was performed to analyze the effect of oral anticoagulant (OAC), new oral anticoagulant (NOAC), warfarin, antiplatelet, left atrial appendage occlusion (LAAO) and no therapy in patients with AF after intracranial hemorrhage. (3) Results: We included 16 studies involving 25,483 patients. Compared with no antithrombotic therapy, the risk of thromboembolism and all-cause mortality were both reduced with OAC (OR: 0.38, 95% CI: 0.21–0.67; OR: 0.45, 95% CI: 0.25–0.8) and LAAO (OR: 0.11, 95% CI: 0.01–0.76; OR: 0.11, 95% CI: 0.01–0.88), and there was no increased risk of recurrent intracranial hemorrhage. Regarding thromboembolism, OAC (OR: 0.28, 95% CI: 0.11–0.69) was superior to antiplatelet therapy, and antiplatelet therapy (OR: 12.59, 95% CI: 1.57–133.50) was associated with a higher risk of thromboembolism than LAAO. There were no significant differences in recurrent intracranial hemorrhage between the interventions. LAAO appeared to be the best option for reducing thromboembolism (SUCRA: 0.96), recurrent intracranial hemorrhage (SUCRA: 0.75) and all-cause mortality (SUCRA: 0.94). (4) Conclusions: Based on this network meta-analysis, we hypothesize that LAAO has the highest likelihood of reducing the risk of thromboembolism and recurrent intracranial hemorrhage, as well as all-cause mortality in patients with AF after intracranial hemorrhage, followed by OAC.

Objective: May–Thurner syndrome typically refers to symptoms and signs arising from the compression of the left common iliac vein by the right common iliac artery. However, such clinical manifestations can occur in the setting of compression of the right common iliac vein and/or either external iliac vein. Given this scenario, the more appropriate term for the condition would be non-thrombotic iliac vein lesion(s) [NIVL]. The goal of this review of large sample size studies is to evaluate outcomes following stenting for chronic iliofemoral venous obstruction (CIVO) due to NIVL, including clinical, quality-of-life, and stent-related outcomes. Additionally, where evidence gaps or controversies exist, expert opinion has been offered for guidance. Methods: A review of the literature was undertaken to determine the role of stenting for NIVL. Appropriate search terms were used to search PubMed, Cochrane Central Register of Controlled Trials, and EMBASE. Studies were only included if they had a sample size of at least 100 limbs that underwent stenting for NIVL and had at least 12 months of follow-up. Additionally, every study needed to have at least one metric of objective clinical evaluation [Venous clinical severity score (VCSS)] and/or a quality-of-life (QoL) measure (generic or venous disease-specific). Results: A total of six studies met the eligibility criteria and included 1404 limbs that underwent stenting for NIVL. All except three studies had a combination of PTS and NIVL limbs, with all six studies having at least 100 limbs that underwent stenting for NIVL. Follow-up varied from 12 to 50 months post-stenting. Improvements in VCSS and quality-of-life measures were noted post-stenting. Additional outcome measures, like grade of swelling or visual analog scale pain score, when utilized, also demonstrated improvement. Recurrence-free ulcer healing rates of 63% to 82% were observed. Good long-term stent primary stent patencies (74–98%) were also reported, irrespective of stent type. Conclusions: This review notes that good outcomes can be expected following stenting for CIVO due to NIVL. Gaps, however, exist with regard to patient selection, peri/post-procedural antithrombotic strategies, and long-term follow-up in this context. A CEAP clinical class-based algorithm is provided to help with patient selection in addition to guidance on antithrombotic therapy and follow-up. Further study of these areas is merited.

Background/Objectives: Complex aneurysms of the posterior inferior cerebellar artery (PICA) remain challenging because of their deep location, variable morphology, and proximity to critical neurovascular structures. Although endovascular therapy is preferred, its feasibility is limited in wide-necked, fusiform, or dissecting lesions. We describe our tertiary referral hospital single-center experience with tailored microsurgical and endovascular strategies—emphasizing occipital artery–PICA (OA-PICA) bypass, transcondylar fossa craniotomy, and cerebellomedullary fissure opening—and analyze perioperative factors that influence outcome. Methods: All consecutive patients treated for PICA origin or distal-PICA aneurysms between January 2021 and April 2025 were retrospectively reviewed. Demographics, aneurysm characteristics, procedure type, antithrombotic regimen, complications, diffusion-weighted MRI findings, and 3-month modified Rankin Scale scores were collected. Results: Twelve aneurysms (mean age 61.4 ± 15.2 years; 8 women) were treated: trapping + OA-PICA bypass in 5, direct clipping in 2, flow diverter in 1, endovascular parent artery occlusion in 2, coil embolization in 1, and a hybrid bypass-plus-coil strategy in 1. Two cases were ruptured aneurysms. Perioperative aspirin was used in 2/5 bypass cases; heparin was added in one hybrid case. Asymptomatic PICA-territory infarcts occurred in the three bypasses performed without antiplatelet therapy (one with intra-anastomotic thrombus). No leaks or subcutaneous collections of cerebrospinal fluid were encountered, and no graft occlusions were observed. At 3 months, 9/12 patients achieved a good outcome (mRS 0–2); among them, only one patient with subarachnoid hemorrhage (SAH) experienced postoperative worsening of the mRS. Two cranial nerve palsies (one permanent, one transient) and one wound site hematoma (heparin-associated) resolved without sequelae. Conclusions: Meticulous operative planning allows safe treatment of complex PICA aneurysms. Perioperative aspirin appears beneficial for OA-PICA bypass, whereas perioperative heparin increases bleeding risk. Individualized selection of endovascular, microsurgical, or combined strategies yields favorable early neurological outcomes in this demanding subset of cerebrovascular disease. Full article

Garlic (Allium sativum L.) has served as a food source and medicinal agent for over thousands of years. Bioactive constituents, including allicin, diallyl sulfide/disulfide/trisulfide, ajoene, and S-allyl-cysteine, demonstrate antioxidant, anti-inflammatory, antithrombotic, antineoplastic, antimicrobial and neuroprotective properties. Convergent mechanistic evidence suggests the modulation of redox homeostasis, attenuation of pro-inflammatory signaling, regulation of platelet activation, and induction of apoptosis and cell-cycle arrest in tumor models. Computational studies, in conjunction with wet-lab data, offer molecular-level insights and guide candidate prioritization. Density functional theory elucidates radical-scavenging pathways and electronic descriptors that account for redox activity. Structure-based methods, including docking, molecular dynamics, and MM-GBSA, elucidate potential interactions between organosulfur scaffolds and enzymes or receptors pertinent to pharmacological effects. In silico ADME/Tox platforms predict generally favorable oral absorption for hydrophobic allyl sulfides, while polar derivatives exhibit more limited brain penetration. Emerging AI/ML pipelines combine network pharmacology with QSAR to focus on important targets and chemical types, while also spotting potential development. Formulation strategies, including nanoencapsulation and controlled-release systems, are utilized to stabilize labile thiosulfinates and modulate hydrogen-sulfide-releasing profiles, with potential applications in various disease conditions. Significant challenges encompass the standardization of preparations, variability in pharmacokinetics, heterogeneity in dose–response relationships, and interactions between drugs and nutrients or other drugs. The integration of mechanistic, computational, and formulation insights delineates a systematic approach to progress garlic-derived agents from diverse natural products to reproducible, mechanism-guided pharmaceuticals.

The coronary no-reflow phenomenon remains a daunting and unresolved barrier during percutaneous coronary procedures, especially for acute coronary syndrome. Despite successful epicardial artery patency restoration, decreased microvascular perfusion leads to unfavorable outcomes such as ventricular remodeling, progression of heart failure, and increased mortality. This review provides a new, integrative informative perspective by combining multifactorial pathophysiology, which includes systemic inflammation, thrombogenicity, ischemia–reperfusion injury, and distal embolization, with advances in diagnostic imaging, such as cardiac magnetic resonance and computed tomography. Therapeutic options, including antithrombotic regimes, vasodilators, and mechanical adjuncts, are evaluated in the context of developing debates and unmet clinical needs. Importantly, we provide feasible future directions for artificial intelligence-based predictive modeling and targeted microvascular treatments. This comprehensive review fills a significant gap, aiming to inform personalized approaches and improve both short- and long-term outcomes in this high-risk patient population. Full article

Novel antidiabetic drugs introduced in the last decade have not only revolutionized the treatment of type 2 diabetes mellitus but have also changed our cardiovascular risk reduction strategy. Glucagon-like peptide-1 (GLP-1) receptor agonists reduce the risk of atherosclerotic diseases primarily through their complex anti-atherosclerotic effect due to their endothelial function-improving, anti-inflammatory, anti-thrombotic, and plaque-stabilizing effects. Sodium–glucose cotransporter 2 (SGLT2) inhibitors, on the other hand, have a favorable cardiovascular effect, mainly by increasing sodium excretion, reducing plasma volume, enhancing the use of ketone bodies as metabolic substrates in heart and kidney tissues, and reducing oxidative stress and uric acid serum levels. However, when using these two groups of drugs, important questions arise. What criteria should be used to decide on the administration of one or the other class of drugs? Which group of agents can be used more effectively to reduce our patients’ cardiovascular risk? What are the possible adverse effects? What can be gained by combining the two drugs? Our objective was to provide a current literature-based and comparative summary on the mechanisms of action, cardiovascular-risk-reducing efficacy, and safety profiles of these two drug classes, with an emphasis on identifying key factors influencing everyday clinical decision-making.

Several nutraceuticals demonstrate potential cardiovascular benefits through lipid-lowering, antithrombotic, and vascular protective mechanisms. Omega-3 fatty acids, berberine, garlic, and nattokinase exert favorable metabolic and vascular effects, yet their clinical efficacy depends on formulation, dosage, and patient characteristics and may be limited by bleeding risk or drug interactions. Antioxidant agents such as vitamin C, vitamin E, resveratrol, astaxanthin, and coenzyme Q provide additional vascular protection but can interfere with hemostasis, metabolism, or redox-sensitive pathways. Similarly, ginkgo biloba, ginger, ginseng, and curcumin exhibit anti-inflammatory vascular activity but also increase the risk of bleeding when combined with antithrombotic therapy. Given the variability in evidence and product quality, their use should be individualized, with further large-scale clinical trials needed to establish safety and efficacy. Full article

Backgrounds/Objectives: Atrial fibrillation (AF) confers a fivefold greater risk of acute ischaemic stroke (AIS) relative to normal sinus rhythm. Among patients with AF-related AIS (AFAIS), recurrence is common: AFAIS rate is sixfold higher in secondary versus primary prevention patients. Guidelines recommend oral anticoagulation for primary and secondary prevention on the basis of CHA₂DS₂-VASc. However, guideline adherence is poor for secondary prevention. This is, in part, because the predictive value of CHA₂DS₂-VASc has not been ascertained with respect to recurrence: patients with and without previous stroke were not routinely differentiated in validation studies. We put forth a protocol to (1) validate, and (2) update CHA₂DS₂-VASc for secondary prevention, aiming to deliver a CPR that better captures 90-day recurrence risk for a given AFAIS patient. Overwhelmingly poor quality of reporting has been deplored among published clinical prediction rules (CPRs). Combined with the fact that machine learning (ML) and deep learning (DL) methods are rife with challenges, registered protocols are needed to make the CPR literature more validation-oriented, transparent, and systematic. This protocol aims to lead by example for prior planning of primary and secondary analyses to obtain incremental predictive value for existing CPRs. Methods: The Virtual International Stroke Trials Archive (VISTA), which has compiled data from 38 randomised controlled trials (RCTs) in AIS, was screened for patients that (1) had an AF diagnosis, and (2) were treated with vitamin K antagonists (VKAs) or without any antithrombotic medication. This yielded 2763 AFAIS patients. Patients without an AF diagnosis were also retained under the condition that they were treated with VKAs or without any antithrombotic medication, which yielded 7809 non-AF AIS patients. We will validate CHA₂DS₂-VASc for 90-day recurrence and secondary outcomes (7-day recurrence, 7- and 90-day haemorrhagic transformation, 90-day decline in functional status, and 90-day all-cause mortality) by examining discrimination, calibration, and clinical utility. To update CHA₂DS₂-VASc, logistic regression (LR), extreme gradient boosting (XGBoost), and multilayer perceptron (MLP) models will be trained using nested cross-validation. The MLP model will employ transfer learning to leverage information from the non-AF AIS patient cohort. Results: Models will be assessed on a hold-out test set (25%) using area under the receiver operating characteristic curve (AUC), calibration curves, and F1 score. Shapley additive explanations (SHAP) will be used to interpret the models and construct the updated CPRs. Conclusions: The CPRs will be compared by means of discrimination, calibration, and clinical utility. In so doing, the CPRs will be evaluated against each other, CHA₂DS₂-VASc, and default strategies, with test tradeoff analysis performed to balance ease-of-use with clinical utility. Full article

This study leverages nanoemulsion technology to engineer a novel liquid formulation combining Eicosapentaenoic acid (EPA) and Nattokinase (NK), aiming to enhance their application potential in functional foods. Both EPA and NK are well recognized for their pronounced anti-thrombotic, anti-inflammatory, and lipid-lowering properties, which are critical for the prevention and management of cardiovascular diseases. However, their practical application in functional foods is hampered by inadequate gastrointestinal stability and suboptimal bioavailability. Here, an EPA-NK nanoemulsion was fabricated using high-pressure homogenization technology. We systematically evaluated its environmental stability, anti-thrombotic activity, and intervention efficacy against carrageenan-induced black-tail thrombosis. The results demonstrated that the nanoemulsion not only enhanced the potential for oral bioavailability based on in vitro stability and preliminary in vivo efficacy trends of EPA and NK but also notably potentiated their synergistic anti-thrombotic efficacy, thereby providing robust theoretical and technical support for the development of next-generation health-promoting functional foods targeting thrombotic disorders.

Background/Objectives: The associations between plasma homocysteine and pre-stroke antithrombotic medication and the effects these have on clinical outcomes of patients undergoing ischemic stroke remains unclear. This study aimed to evaluate the combined effect of plasma homocysteine levels and the use of pre-stroke antithrombotic medication on the clinical outcomes of patients experiencing first-ever and recurrent ischemic strokes. Methods: Anonymized data from consecutive patients who experienced ischemic stroke and had their plasma homocysteine levels evaluated were retrospectively analyzed. Pre-stroke antithrombotic medication status, clinical variables potentially influencing homocysteine concentrations, and stroke recurrence data were collected. Clinical outcomes were assessed using the modified Rankin Scale 3 months after stroke onset. The association between hyperhomocysteinemia and clinical outcomes was evaluated using logistic regression models. Results: Hyperhomocysteinemia was significantly associated with unfavorable clinical outcomes (adjusted odds ratio [aOR], 1.32; 95% confidence interval, 1.04–1.69) in the 2767 patients who were analyzed. The absence of pre-stroke antithrombotic medication use was associated with unfavorable outcomes (aOR range, 1.29–1.56), specifically in patients with first-ever stroke (aOR range, 1.45–1.64) but not in patients with recurrent strokes (aOR range, 0.70–1.04). Conclusions: Hyperhomocysteinemia and non-use of pre-stroke antithrombotic medication were significantly related to unfavorable outcomes in patients experiencing their first-ever stroke. These findings might provide prognostic insights into stroke management and patient stratification. Full article

Background: While anticoagulant and antiplatelet therapies are commonly combined in clinical settings, this combination increases the risk of hemorrhage. However, comparative data on the bleeding risks of different drug combinations remain limited. This study assesses hemorrhage risk associated with various anticoagulant–antiplatelet combinations using data from the USFDA Adverse Event Reporting System (AERS). Methods: Hemorrhage-related reports were extracted from the AERS database (March 2004–June 2024). Anticoagulants analyzed included warfarin, rivaroxaban, dabigatran, apixaban, edoxaban, betrixaban, and acenocoumarol; antiplatelets included aspirin, clopidogrel, ticagrelor, cilostazol, prasugrel, and dipyridamole. Disproportionality analysis using frequentist and Bayesian approaches was conducted to detect hemorrhage signals. Results: Out of 160,715 hemorrhage reports, rivaroxaban, warfarin, and apixaban were the most frequently reported anticoagulants, while aspirin and clopidogrel were the top antiplatelets. Apixaban had the lowest reporting odds ratio for hemorrhage. The rivaroxaban-aspirin combination showed the highest hemorrhage risk, while combinations with cilostazol were the lowest. Apixaban, alone and in combination, was associated with reduced hemorrhage and mortality risks. Conclusions: Combining anticoagulants with antiplatelets increases hemorrhage and mortality risk. While our findings highlight potential safety signals related to hemorrhage with antithrombotic drug combinations, they remain hypothesis-generating and should not be interpreted as causal associations. Instead, they provide an initial basis for further validation in well-designed clinical cohorts where comorbidities can be adequately accounted for. Full article

Background: Antithrombotic therapy plays an important role in acute coronary syndrome (ACS). The combination of anticoagulant and antiplatelet therapy resulted in fewer complications and stronger potency compared to traditional monotherapy. Our net meta-analysis aimed to compare and rank the safety of different treatments used in patients with ACS. Method: We conducted a search for trials in three prominent databases. The main objective of our investigation was to assess hemorrhage. Additional outcomes included mortality, myocardial infarction, stroke, and embolism. We used a frequentist network meta-analysis with a random-effects model to, directly and indirectly, compare safety across different antithrombotic strategies. Result: A total of 30 randomized clinical trials were included in this net meta-analysis with 135,471 ACS patients. In these eight different antithrombotic therapies, SAPT (single-agent platelet inhibitor therapy) showed the lowest risk of bleeding (SUCRA = 0.5%). The highest risk of bleeding was observed in VKA (vitamin K antagonists) + DAPT (dual antiplatelet therapy) (SUCRA = 99.8%). Bleeding among NOAC (non-vitamin K antagonist oral anticoagulants) + DAPT was found to be higher than DAPT (OR = 1.94, 95% CI = 1.42–2.65). NOAC + SAPT significantly reduced the embolism (OR = 1.50, 95% CI = 1.16–1.94) and myocardial infarction (OR = 1.22, 95% CI = 1.08–1.37) events compared with SAPT. In addition, VKA significantly reduced the rate of stroke compared with SAPT (OR = 3.45, 95% CI = 1.17–10.18). However, no significant difference was observed in death events among these eight antithrombotic therapies. Conclusions: We advise against the use of SAPT in ACS due to its elevated risk of embolism, myocardial infarction, and stroke. It is important to mention that the combination of NOAC and SAPT has a lower incidence of myocardial infarction, bleeding and embolism problems. Therefore, the combination of NOAC and SAPT may be the optimal approach to achieve a balance between the risks of bleeding and embolism. This meta-analysis was registered in PROSPERO with the registration number CRD42024542826. Full article

Background/Objectives: Pregnancy is associated with increased procoagulant conditions, and when combined with obesity, it can elevate the risk of thrombosis. The study aims to assess thrombosis risk markers during pregnancy in relation to obesity. Methods: Somatically healthy women aged 18–42 years with spontaneous pregnancies who did not receive specific antithrombotic treatment were enrolled in the study (n = 97). The participants were divided into groups based on pregestational BMI: the first group consisted of patients who had a BMI ≤ 25 (n = 42), and the second group consisted of patients who were overweight (BMI > 25) and obese (BMI > 30) (n = 55). The control group comprised healthy, non-pregnant, non-obese women (n = 10). Results: Fibrinogen levels, elevated during pregnancy, were higher in the II and III trimesters, with gestational period having a greater influence than BMI. Moderate D-dimer accumulation was observed regardless of obesity, but higher levels were seen in obese women during the III trimester, indicating the dissolution of intravascular fibrin deposits. Soluble fibrin was significantly higher in obese and overweight women during the II trimester and elevated in both groups during the III trimester, correlating with D-dimer accumulation and indicating thrombus formation. A decrease in platelet aggregation ability was observed correlating with D-dimer and soluble fibrin patterns. Conclusions: A significant accumulation of thrombosis risk markers was observed in the III trimester compared to the II, occurring earlier in obese and overweight pregnant women and indicating a higher risk of thrombotic complications in obesity.
