Acute Coronary Syndrome (ACS) continues to be a leading cause of death and illness worldwide. Differentiating stable from unstable coronary plaques is essential for enhancing patient outcomes. This research investigates the role of CD147 as a biomarker for plaque stability among coronary artery disease patients.
The study began with high-throughput sequencing of blood samples from six patients, divided equally between those with Stable Angina (SA) and Unstable Angina (UA), followed by bioinformatics analysis. Expanding upon these findings, the study included 31 SA patients and 30 patients with ACS, using flow cytometry to examine CD147 expression on platelets and monocytes. Additionally, logistic regression was utilized to integrate traditional risk factors and evaluate the predictive value of CD147 expression for plaque stability.
Initial sequencing displayed a notable difference in CD147 expression between SA and UA groups, with a significant increase in UA patients. Further analysis confirmed that elevated platelet CD147 expression was strongly associated with unstable plaques (OR = 277.81, < .001), after adjusting for conventional risk factors, whereas monocyte CD147 levels did not show a significant difference.
Elevated CD147 expression on platelets is a crucial biomarker for identifying unstable coronary artery plaques, offering insights into patient risk stratification and the development of targeted treatment strategies. This underscores the pivotal role of molecular research in understanding and managing coronary artery disease, paving the way for improved clinical outcomes.
急性冠状动脉综合征(ACS)仍是全球范围内死亡和疾病的主要原因。区分稳定型和不稳定型冠状动脉斑块对于改善患者预后至关重要。本研究调查了CD147作为冠状动脉疾病患者斑块稳定性生物标志物的作用。
该研究首先对6例患者的血样进行高通量测序,这些患者在稳定型心绞痛(SA)和不稳定型心绞痛(UA)患者中平均分配,随后进行生物信息学分析。基于这些发现进行拓展,该研究纳入了31例SA患者和30例ACS患者,使用流式细胞术检测血小板和单核细胞上CD147的表达。此外,利用逻辑回归整合传统危险因素,并评估CD147表达对斑块稳定性的预测价值。
初始测序显示SA组和UA组之间CD147表达存在显著差异,UA患者中显著增加。进一步分析证实,在调整传统危险因素后,血小板CD147表达升高与不稳定斑块密切相关(OR = 277.81,< 0.001),而单核细胞CD147水平未显示出显著差异。
血小板上CD147表达升高是识别不稳定冠状动脉斑块的关键生物标志物,为患者风险分层和制定靶向治疗策略提供了见解。这突出了分子研究在理解和管理冠状动脉疾病中的关键作用,为改善临床结局铺平了道路。
