Cardiovascular disease (CVD) remains a leading cause of global morbidity and mortality, and its initiation and progression are closely associated with multiple molecular mechanisms. Neutrophil extracellular traps (NETs) are mesh-like structures composed of DNA, histones, and antimicrobial proteins that are released by neutrophils during inflammation or infection. They play a crucial role in innate immune defense. However, when the dynamic balance of NETs is disrupted by excessive formation, persistent accumulation, or impaired clearance, NETs are no longer merely bystanders. Instead, they actively drive pathological processes in multiple CVDs and serve as a critical link between inflammation and cardiovascular injury. Given the central role of NETs in CVD pathogenesis, including atherosclerosis, myocardial ischemia–reperfusion injury, pulmonary arterial hypertension, atrial fibrillation, and heart failure, therapeutic strategies targeting NETs, such as inhibiting aberrant formation, enhancing clearance, or neutralizing toxic components, have emerged as promising approaches. In recent years, traditional Chinese medicine (TCM) and natural products have shown potential therapeutic value by modulating NET formation and promoting NET degradation, owing to their multitarget, multipathway regulatory effects. This article reviews the mechanisms by which NETs operate in CVDs and explores potential pathways through which TCM and natural active ingredients prevent and treat CVDs by regulating NETs. This review provides theoretical support for further research and clinical application.
