Objective To explore the effect of indobufen combined with intelligent resistance training on platelet function and cardiac function in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI). Methods A total of 60 ACS patients who underwent PCI stent implantation in our hospital from January 2024 to December 2025 were selected and randomly divided into an observation group and a control group, with 30 patients in each group. The control group was given conventional treatment combined with clopidogrel 75 mg/d, while the observation group was given conventional treatment combined with indobufen (100 mg/time, twice a day) + intelligent resistance training intervention. Both groups received continuous intervention for 3 months. The arachidonic acid (AA)-induced and adenosine diphosphate (ADP)-induced platelet aggregation rates were compared between the two groups before intervention, 1 month and 3 months after intervention. The incidence of major adverse cardiovascular events (MACE) was followed up for 3 months, and the cardiac function indexes [left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD)] were compared before and after intervention. Results Before intervention, there were no significant differences in platelet aggregation rates, LVEF and LVEDD between the two groups (P > 0.05); at 1 month and 3 months after intervention, the reduction amplitudes of AA-induced and ADP-induced platelet aggregation rates in the observation group were significantly greater than those in the control group (P < 0.05); after 3 months of intervention, LVEF in the observation group was significantly higher than that in the control group, and LVEDD was significantly lower than that in the control group (P < 0.05); after 3 months of follow-up, there was no significant difference in the incidence of MACE between the two groups (P > 0.05). Conclusion Indobufen combined with intelligent resistance training can more significantly inhibit platelet aggregation, more effectively improve cardiac function indexes in ACS patients after PCI, and has good safety.
泛血管疾病（PVD）是一类以动脉粥样硬化为共同病理基础、累及心、脑、肾及外周血管系统的临床综合征, 具有多血管床共病特征, 发病率高、致残致死率大。非编码RNA（ncRNA）作为基因表达的重要调控因子, 在PVD的发生发展中发挥关键作用。微小RNA（miRNA）、长链非编码RNA（lncRNA）、环状RNA（circRNA）等ncRNA通过调节炎症反应、内皮功能、血管重塑、代谢稳态等多路径参与PVD的病理过程, 并展现出时空特异性和双向调控特征。最新研究揭示ncRNA在临床中的诊断预测及靶向干预潜力, 包括外泌体载体及circRNA递送系统等新策略。此外, 中医药通过调控ncRNA网络, 干预血瘀、痰浊等证型相关通路, 体现中西医结合治疗的系统优势。本文系统综述了ncRNA在PVD中的作用机制与研究进展, 强调其在精准诊疗与转化研究中的应用前景, 并指出未来需加强基础与临床协同、推进个体化干预策略的落地实施。
Panvascular diseases（PVD）are a group of clinical syndromes characterized by atherosclerosis as a common pathological foundation, involving heart,brain,kidneys,and peripheral vascular systems．These diseases often exhibit multi-vascular bed comorbidities and are associated with high incidence,disability, and mortality rates．Non-coding RNAs（ncRNAs）, as key regulators of gene expression, play a crucial role in the onset and progression of PVD．Various types of ncRNAs—including microRNAs（miRNAs）, long non-coding RNAs（lncRNAs）, and circular RNAs（circRNAs）—are involved in the pathological processes of PVD through multiple pathways, such as modulation of inflammatory responses, endothelial function, vascular remodeling, and metabolic homeostasis, exhibiting spatiotemporal specificity and bidirectional regulatory effects．Recent studies have highlighted the potential of ncRNAs in clinical diagnosis, prognosis, and targeted therapy,with novel strategies including exosome-based delivery and circRNA-targeting systems．In addition, traditional Chinese medicine（TCM）exerts regulatory effects on ncRNA networks to intervene in syndrome-specific pathways, such as those related to blood stasis and phlegm-dampness, reflecting the systemic advantages of integrating TCM with Western medicine．This review systematically summarizes the regulatory mechanisms and research progress of ncRNAs in PVD,emphasizes their potential in precision medicine and translational research, and proposes the need to strengthen collaboration between basic and clinical studies to facilitate the implementation of personalized therapeutic strategies．
