Blood stasis syndrome of coronary heart disease: A perspective of modern medicine / 中国结合医学杂志

ABSTRACT

The medical community as a whole is attempting to start preventive therapy for coronary heart disease (CHD) patients earlier in life. However, the main limitations of such interventions are drug resistance and adverse reactions. Additionally, traditional biomarker discovery methods for CHD focus on the behavior of individual biomarkers regardless of their relevance. These limitations have led to attempting novel approaches to multi-dimensionally investigate CHD and identify safe and efficacious therapies for preventing CHD. Recently, the benefit of Chinese medicine (CM) in CHD has been proven by increasing clinical evidence. More importantly, linking CM theory with modern biomedicine may lead to new scientific discoveries. According to CM theory, all treatments for patients should be based on patients' syndromes. A recent epidemiological investigation has demonstrated that blood stasis syndrome (BSS) is the major syndrome type of CHD. BSS is a type of complex pathophysiological state characterized by decreased or impeded blood flow. Common clinical features of BSS include a darkish complexion, scaly dry skin, and cyanosis of the lips and nails, a purple or dark tongue with purple spots, a thready and hesitant pulse, and stabbing or pricking pain fixed in location accompanied by tenderness, mass formation and ecchymosis or petechiae. The severity of BSS is significantly correlated with the complexity of coronary lesions and the degree of stenosis, and is an important factor affecting the occurrence of restenosis after percutaneous coronary intervention. The mechanisms of BSS of CHD patients should be investigated from a modern medicine perspective. Although many studies have attempted to explore the biomedical mechanisms of BSS of CHD, from hemorheological disorders to inflammation and immune responses, the global picture of BSS of CHD is still unclear. In this article, the current status of studies investigating the biomedical mechanisms of BSS of CHD and future perspectives are discussed.
