Background:Drug-coated balloons (DCB) represent a novel therapeutic approach for treating native coronary artery disease. However, the clinical outcomes of DCB in patients with left anterior descending (LAD) artery stenosis proximal to a myocardial bridge (MB) remain unclear. This study aims to investigate the effects of DCB in patients with LAD artery stenosis proximal to MB. Method:This retrospective cohort study included consecutive patients with LAD artery stenosis proximal to MB who underwent DCB or drug-eluting stent (DES) procedures between January 2020 and July 2021. The DCB group comprised 30 patients treated with DCB alone, while the DES group included 105 patients treated with DES alone. Major adverse cardiac events (MACEs) during a median follow-up of 507 days (IQR 391.5-622.0 days) were defined as a composite of unstable angina requiring hospitalization, acute myocardial infarction, cardiac death, and target lesion revascularization (TLR). Results:Both groups exhibited generally comparable baseline clinical and lesion characteristics, except for age and MB systolic compression. Over a median follow-up of 507 days (IQR 391.5-622.0 days), Kaplan-Meier survival analysis revealed no statistically significant difference in MACE-free survival rates between the two groups (73.96%, 95% CI 55.8-98.0 vs. 82.49%, 95% CI 73.9-90.8; Log-rank P = 0.678). Cox proportional regression analysis showed no statistically significant difference in MACEs between DCB and DES patients (HR = 1.58, 95% CI = 0.56-4.45, P = 0.383). Conclusion:In this exploratory retrospective study, we did not detect a statistically significant advantage of DCB over DES in treating LAD stenosis proximal to MB. Given the limited sample size, these findings should be considered preliminary and do not support DCB as a reasonable alternative to DES. Larger prospective studies are warranted to validate the potential role of DCB in this specific anatomical setting.
The underlying proinflammatory mechanism of coagulation factor VⅡ in coronary artery disease (CAD) remains unclear. According to the inclusion criteria, 24 non-CAD subjects and 24 patients with CAD were enrolled. The expression levels of pro-inflammatory (CD14+CD86+, CD14+CD163-), anti-inflammatory monocytes (CD14+CD163+), CD14+CD142+ and CD14+PAR2+ monocytes in peripheral blood were detected by flow cytometry. The levels of TNF-α, IL-1β, IL-6, IL-10, and FVⅡ in plasma were determined by ELISA. In vitro experiments were conducted to induce inflammatory THP-1 by FVⅡa. The FVⅡa/TF complex inhibitor PCI-27,483 and PAR2 antagonist AZ3451 were used to clarify the mechanisms. Compared with the control group, the percentage of CD14+CD86+ pro-inflammatory monocytes were significantly increased in the CAD group, and further elevated after PCI. The results of the levels of CD14+CD142+ and CD14+PAR2+ monocytes showed the same trends with CD14+CD86+ pro-inflammatory monocytes. The levels of CD14+CD163+ anti-inflammatory monocytes and IL-10 were decreased in CAD patients, but increased after PCI. The pro-inflammatory factors and FVⅡ were significantly elevated in the CAD group and significantly decreased after PCI. Correlation analysis revealed that FVⅡ, TF, and PAR2 were significantly associated with CD14+CD86+ pro-inflammatory monocytes, and inflammatory factors. In vitro studies further confirmed that the FVⅡa/TF coagulation complex and PAR2 could activate NF-κB in monocytes and aggravate inflammation. Our findings suggest that crosstalk between monocytes and the coagulation complex might contribute to residual inflammation in CAD, potentially involving the FVIIa/TF/PAR2-NF-κB signaling pathway. Based on these observations, we hypothesize that blocking the interaction between clotting factors and monocytes could represent a promising therapeutic strategy to mitigate residual inflammation, but further rigorous experiments are needed for verification. Crosstalk between the monocytes and coagulation complex might cause residual inflammation in CAD. FVⅡa/TF/PAR2-NF-κB signal pathway is related to the activation of monocytes. Blocking the interaction between FVⅡa/TF coagulation complex and monocytes might be a promising therapeutic target to reduce residual inflammation.
Early identification of high-risk individuals for coronary artery disease (CAD) is critical, especially in acute coronary syndrome (ACS) patients who face elevated risks of adverse cardiovascular events and are in need of intensified secondary prevention. This study aimed to investigate the combined value of the triglyceride-glucose (TyG) index—a surrogate marker of insulin resistance—and the systemic inflammatory response index (SIRI), calculated as (neutrophil count × monocyte count)/ lyphocyte count, in assessing coronary artery stenosis severity, proposing a cost-effective strategy for risk stratification in ACS management. A retrospective cohort study included 415 ACS patients diagnosed by coronary angiography at Beijing University of Chinese Medicine Third Affiliated Hospital (June 2021–February 2024). Patients were stratified into low stenosis (Gensini score < 34, n = 204) and high stenosis (Gensini score ≥ 34, n = 211) groups based on the median Gensini score. Clinical parameters and inflammatory markers were analyzed using logistic regression and ROC curves. High stenosis group showed significantly higher TyG (1.95 vs. 1.42, P < 0.001) and SIRI (1.07 vs. 0.75, P < 0.001) than the low stenosis group. Both indices independently associated with severe stenosis (OR = 3.094 and 2.064, P < 0.001). The combined TyG-SIRI model achieved an AUC of 0.744 (sensitivity 61.61

Abstract Background Heart failure (HF) is a global public health problem with high morbidity and mortality. While machine learning (ML) has been perceived as a promising tool for HF research, a bibliometric analysis of this application is still lacking. This study aims to analyze the relevant papers from 2003 to 2023 and provide a comprehensive overview of this field in a visual way. Methods We systematically searched Web of Science Core Collection, PubMed, and preprint servers (arXiv, BioRxiv, and MedRxiv) to identify records from 2003 to 2023 on ML in HF research. After manual data cleansing, a Python approach based on the regular expression matching algorithm was used to automate text annotations, while three bibliometric analysis tools (CiteSpace, VOSviewer, and Bibliometrix) were used for the visualization of research trends, collaboration networks, and research hotspots. Results We analyzed 6,115 records (including 1,797 published papers) and observed a steady increase in annual publication rates since 2015, with a significant uptick after 2020. We identified 23 core journals in the field according to Bradford's law, and presented the top 10 journals with the highest citations, h-index, g-index, or m-index. The United States was the most productive country, followed by China and the United Kingdom. The most prolific institutions were Harvard Medical School and Mayo Clinic. Using text annotations, we identified 1,257 ML-related original HF research. In these studies, the main data modalities were ultrasound, electronic health records, and electrocardiograms. The most frequently applied ML methods were neural networks, followed by linear models and ensembles. The most common clinical goals were diagnosis, prediction, and classification. The main research topics included the classification of HF, AI-assisted medical diagnostic technologies, HF-related clinical prediction models, and HF-related bioinformatics research. Conclusions This bibliometric analysis revealed a significant growth in the application of ML in HF research over the past two decades. The current research landscape encompasses a wide range of ML techniques and applications, focusing on improving diagnosis, prognosis, classification, and precision treatment for HF patients.

Objectives: Wuling capsule has been used in treatment of insomnia disorder in China for decades, but the reported treatment efficacy of different studies was not consistent. This study intended to evaluate the efficacy and safety of Wuling capsule for insomnia disorder, so as to provide evidence for clinical application. Methods: Eight databases (MEDLINE, EMBASE, Ovid, Cochrane Library, Chinese National Knowledge Infrastructure, VIP information database, Chinese Biomedical Database and Wanfang) were searched from inception to September 14, 2021. Randomized controlled trials (RCTs) comparing Wuling capsule with controls in adults with insomnia disorder were eligible. The primary outcome was sleep quality assessed by Pittsburgh Sleep Quality Index (PSQI), and the secondary outcomes were severity of insomnia disorder measured by Sleep Dysfunction Rating Scale (SDRS) and adverse events. This study was conducted according to the Cochrane Handbook for Systematic Reviews of Interventions version 5.1.0. Results: Nineteen RCTs with a total of 1850 participants were included. In terms of sleep quality assessed by PSQI, Wuling capsule significantly lowered PSQI score (MD:-1.92, 95% CI: [-2.34,-1.50], P < 0.00001, I-2 = 95%) compared to controls, and the effect of Wuling capsule was significantly better than control no matter when Wuling capsule as monotherapy (MD:-1.71, 95% CI: [-2.33,-1.09], P < 0.00001, I-2 = 97%) or as adjunctive therapy (MD:-2.10, 95% CI: [-2.66,-1.55], P < 0.00001, I-2 = 90%). Wuling capsule was more effective for the treatment duration lasted 8 weeks (MD:-2.57, 95% CI: [-3.52,-1.62], P < 0.00001, I-2 = 93%) than 4 weeks (MD:-1.68, 95% CI: [-2.13,-1.22], P < 0.00001, I-2 = 95%). In terms of severity of insomnia disorder measured by SDRS, Wuling capsule significantly reduced SDRS score (MD:-4.21, 95% CI: [-4.95,-3.46], P < 0.00001, I-2 = 0%) compared to benzodiazepines. Wuling capsule significantly reduced adverse events compared to controls (RR: 0.47, 95% CI: [0.34, 0.65], P < 0.00001, I-2 = 43%). Conclusion: Wuling capsule can safely and effectively improve sleep quality in patients with insomnia disorder. However, these findings require careful recommendation due to the high heterogeneity and high risk of bias in the included trials. Clinical trials with higher quality designs are needed.

Background: Lipid-lowering therapy is very important in secondary prevention of coronary heart disease (CHD). In many clinical trials, it has been found that Sodium Tanshinone IIA Sulfonate Injection (STS) have a lipid-lowering effect while reducing major cardiovascular events in patients with CHD. However, up to now, there is no system review on the effectiveness and safety of STS affecting blood lipids.Purpose: The aim of this review is to systematically assess the effects of STS on blood lipid levels in patients with CHD.Methods: Until Mar 2021, five databases (PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure, and Wanfang Database) were searched for randomized controlled trials (RCTs) about STS treating patients with CHD. Risk bias was assessed for included studies according to Cochrane handbook. The primary outcome was total cholesterol (TC). The secondary outcomes were triglycerides (TG), low-density lipoprotein cholesterol (LDL-c), high-density lipoprotein cholesterol (HDL-c), and adverse events (AEs).Results: A total of 27 trials including 2,445 CHD patients met the eligibility criteria. Most trials had high risks in random sequence generation, allocation concealment, blinding of patients and personal, blinding of outcome assessment. Meta-analysis showed that STS significantly reduced plasma TC levels [MD = -1.34 mmol/l 95% CI (-1.59, -1.09), p < 0.00001, I-2 = 98%], TG levels [MD = -0.49 mmol/l 95% CI (-0.62, -0.35), p < 0.00001, I-2 = 97%], LDL-c levels [MD = -0.68 mmol/l (-0.80, -0.57), p < 0.00001, I-2 = 96%], increased HDL-c levels [MD = 0.26 mmol/l (0.15, 0.37), p < 0.00001, I-2 = 97%], without increasing the incidence of AEs [RR = 1.27 95% CI (0.72, 2.27), p = 0.94, I-2 = 0%] in patients with CHD.Conclusion: STS can safely and effectively reduce plasma TC, TG and LDL-c levels in patients with CHD, and improve plasma HDL-c levels. However, these findings require careful recommendation due to the low overall quality of RCTs at present. More multi-center, randomized, double-blind, placebo-controlled trials which are designed follow the CONSORT 2010 guideline are needed.

目的 探讨风速对冠状动脉粥样硬化性心脏病(冠心病)心血管事件的影响.方法 收集铜川地区2017~2018年650例冠心病患者的临床资料和同期气象资料、环境污染资料,回顾性分析风速与心血管事件的相关性.结果 650例冠心病患者累计发生心血管事件754次,包括心源性死亡9例、非致命性心肌梗死59例、不稳定型心绞痛506例、急性心力衰竭50例、卒中85例.单因素分析显示,日均风速与心血管事件显著相关(OR=1.58,95%CI:1.02~2.45).多因素Logistic回归分析显示,相对于低风速(0.70~1.90 m/s),中等风速(2.00~2.60 m/s)发生心血管事件的风险显著增加(OR=3.29,95%CI:1.49~7.26).结论 一定范围的风速增高会增加冠心病患者心血管事件风险.
近年来,随着介入心脏病技术的发展、新型药物及器械的研发、一级和二级预防策略使数以千万冠状动脉粥样硬化性心脏病(冠心病,CHD)患者受益,使CHD的死亡率大幅下降,然而对冠状动脉微血管病变(CMVD)却力有未逮.有50%的冠心病患者接受经皮冠状动脉介入治疗(PCI)后仍有胸痛发作[1],PCI虽可开通狭窄的冠状动脉(冠脉),但却对于直径<0.1 mm的冠脉微血管却无能为力.临床上很大一部分患者,虽具有典型心绞痛症状,但冠脉造影检查并未发现明显的狭窄(其冠脉狭窄程度<50%),称为X综合征,既往认为其长期预后良好,但目前研究发现其主要心血管事件和全因死亡率显著高于对照人群[2].由于现阶段对CMVD缺乏有统一的诊断标准,且在治疗方面,药物的选择也存在很大分歧,相当一部分有着顽固性心绞痛症状,但冠脉造影阴性的患者,在临床上并未得到有效治疗,使得CMVD成为心血管领域亟待解决的问题.
目的 通过文献计量学对现代文献从风论治冠心病证候分布及用药规律进行总结,为冠心病风邪致病的理论和临床实践提供参考.方法 检索中国期刊全文数据库、万方数据库、中文期刊服务平台从风论治冠心病相关的现代文献,采用SPSS 21.0统计软件对证候、临床表现及风药进行频数统计.结果 共检索到相关文献1 595篇,最终纳入20篇,共10种证候类型,从风论治冠心病常见的中医证型为气虚血瘀证;风邪侵袭常见的病位为心络;治疗冠心病常用风药为黄芪、川芎、羌活、威灵仙、芍药、葛根.结论 风邪与冠心病气虚血瘀证密切相关且最易侵袭心络,“益气活血、祛风通络”是从风论治冠心痛的重要治法.
