The prognosis of patients with MI has improved significantly with the recognition that early reperfusion is critical, particularly since timely percutaneous coronary intervention (PCI) became widely adopted. The invasive reperfusion era also reshaped MI diagnostics, shifting the paradigm from Q-wave vs. Non-Q-wave MI to ST-Elevation Myocardial Infarction (STEMI) vs. Non-ST-Elevation Myocardial Infarction (NSTEMI).
The current ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI) paradigm have long been the cornerstone of myocardial infarction (MI) care but fail to identify many patients with acute coronary occlusion (ACO), delaying treatment and worsening outcomes. This limitation is increasingly important, since NSTEMI now represents the majority of presentations accounting for roughly 70% of AMI worldwide and many of these occlusive events are managed with delays contributing to worse outcomes. Adding to this challenge, substantial inter-physician variability in ECG interpretation for ACO has been demonstrated.
In this review, we highlight recent advances using the artificial intelligence in the evaluation of patients presenting with ECG changes suggestive of NSTEMI and evaluate its role in the detection of NSTEMI patients with acute coronary occlusion.

Cardiovascular diseases (CVDs) remain the leading global cause of morbidity and mortality, with growing evidence highlighting the immune system as a central regulator of disease initiation and progression. Recent advances have uncovered pivotal roles for innate lymphoid cells (ILCs) and trained innate immunity (TI) in shaping cardiovascular homeostasis and inflammation. This review synthesizes current knowledge on the development, tissue residency, and functional specialization of ILC subsets, including ILC1/NK cells, ILC2, and ILC3, as well as their divergent contributions to atherosclerosis, myocardial infarction, heart failure, myocarditis, and pericarditis. ILC1 and NK cells promote vascular inflammation and plaque progression, whereas cardiac-resident ILC2s exert reparative, anti-inflammatory, and atheroprotective effects. Parallel evidence shows that TI, driven by metabolic stressors such as hyperglycemia, oxidized LDL, smoking, and a Western diet, induces persistent myeloid reprogramming that amplifies vascular inflammation and accelerates CVD. We further highlight their potential as diagnostic biomarkers and therapeutic targets, including cytokine-directed interventions, modulation of the IL-33/ILC2 axis, and epigenetic therapies. Together, these insights position ILC biology and TI as transformative frameworks for advancing precision immunocardiology.

Diet high in sodium is an established major risk factor for cardiovascular diseases (CVDs), yet a comprehensive and updated assessment of its attributable disease burden, particularly comparing China with global patterns over the last three decades, is lacking.
Methods
This study aims to quantify and compare the deaths and disability-adjusted life years (DALYs) of CVDs attributable to diet high in sodium in China and globally from 1990 to 2021. Using data from the Global Burden of Disease (GBD) Study 2021, we applied the comparative risk assessment framework to estimate the sodium-attributable CVD burden. Mortality and DALYs were analyzed as absolute numbers and age-standardized rates (ASRs). Temporal trends were assessed using estimated annual percentage changes (EAPCs), and future burden to 2046 was projected using an age-period-cohort (APC) model.
Results
In 2021, diet high in sodium was responsible for 1.71 million [95 % uncertainty intervals (UI): 0.36-3.81 million] global deaths and 37.77 million (95 % UI: 9.05-80.81 million) DALYs. The global age-standardized death rate (ASDR) and DALY rate (ASDAR) were 20.4 and 437.7 per 100,000, respectively. From 1990 to 2021, while absolute death counts increased by 52 %, the ASDR significantly declined (EAPC: -1.46 %). Pronounced sex and age disparities were observed, with males bearing a consistently higher burden and the elderly experiencing the highest rates but slowest improvements. In China, the 2021 ASDR (40.91/100,000) and ASDAR (837.94/100,000) were approximately double the global averages, despite substantial declines since 1990 (ASDR EAPC: -1.74 %; ASDAR EAPC: -1.85 %). Projections to 2046 indicate rising absolute numbers globally and in China, driven by demographic changes, despite continuing declines in age-standardized rates.
Conclusion
High sodium intake remains a major contributor to the global and Chinese CVD burden, with significant sex and age disparities. Although age-standardized rates have improved, the rising absolute burden underscores the imperative for more effective, targeted salt-reduction public health strategies.

Background
Exosomes, nanoscale extracellular vesicles (30–150 nm) carrying bioactive molecules (e.g., miRNAs, proteins), have emerged as pivotal mediators in cardiovascular diseases (CVDs), offering potential as diagnostic biomarkers and therapeutic vectors. Despite growing interest, a comprehensive analysis of global research trends, hotspots, and translational gaps in exosome applications for CVDs remains limited.
Methods
We conducted a ten-year (2016–2025) bibliometric analysis of 2617 publications from the Web of Science Core Collection, employing integrative tools (LDGAS and KMVS) to map research distribution, collaborations, and citation trends. Data was analyzed for contributions by country, institution, journal, and author, with a focus on mechanistic insights, clinical applications, and technological innovations.
Results
Global publications surged post-2016, with China leading in output (50 % of top institutions) and the USA/Europe dominating citation impact (e.g., Harvard Medical School: 7.83 citations/paper). Three key themes emerged: exosomal regulation of oxidative stress, inflammation, and angiogenesis; engineered exosomes (e.g., inflammation-targeting macrophage exosomes and stem cell-derived exosomes; circulating miRNAs (e.g., miR-21-5p in heart failure). Challenges include heterogeneous exosome isolation methods (<5 % studies reach preclinical trials) and imbalanced collaborations (China-USA partnerships dominated, 83 %).
Conclusions
Exosome research in CVDs demonstrates transformative potential but requires standardized protocols, diversified clinical trials, and strengthened global partnerships. Prioritizing AI-driven biomarker discovery and interdisciplinary synergy will accelerate clinical translation.
体是携带生物活性分子(如mirna、蛋白质)的纳米级细胞外囊泡(30 - 150nm),已成为心血管疾病(cvd)的关键介质,具有作为诊断生物标志物和治疗载体的潜力。尽管人们对外显体在心血管疾病中的应用越来越感兴趣,但对其全球研究趋势、热点和翻译差距的综合分析仍然有限。方法采用综合工具(LDGAS和KMVS)对Web of Science核心馆藏的2617篇论文进行了为期10年(2016-2025)的文献计量学分析,绘制了研究分布、合作和被引趋势。数据按国家、机构、期刊和作者进行分析,重点关注机制见解、临床应用和技术创新。结果2016年后,全球出版物数量激增,其中中国的产量领先(占顶级机构的50%),美国/欧洲的引用影响占主导地位(例如哈佛医学院:7.83次引用/篇)。出现了三个关键主题:氧化应激、炎症和血管生成的外泌体调节;工程化外泌体(如炎症靶向巨噬细胞外泌体和干细胞衍生外泌体);循环mirna(如心力衰竭中的miR-21-5p)。挑战包括异质外泌体分离方法(5%的研究进入临床前试验)和不平衡的合作(中美伙伴关系占主导地位,83%)。结论心血管疾病的染色体研究具有变革潜力,但需要标准化的方案、多样化的临床试验和加强全球伙伴关系。优先考虑人工智能驱动的生物标志物发现和跨学科协同将加速临床翻译。
