Distribution of Non-ST Segment Elevation Myocardial Infarction Syndromes and Traditional Chinese Medicine Intervention Strategies / 中国实验方剂学杂志

ABSTRACT

Objective:To analyze the syndrome characteristics and distribution regularity of patients with non-ST segment elevation myocardial infarction (NSTEMI), in order to guide clinical practice and improve the efficacy of traditional Chinese medicine. Method:Inpatients with non-ST segment elevation myocardial infarction in line with the diagnostic criteria were selected, and the frequency statistics method was used to analyze the syndrome elements and their frequency degree and distribution characteristics. Result:According to the analysis of syndrome elements and their frequency degree of 263 patients with NSTEMI, the pathogenesis of NSTEMI was mostly deficiency in origin and excess in superficiality. As for deficiency in origin, Qi deficiency (171 times, 32.39%) was the most common, which was followed by Yin deficiency (42 times, 7.95%), Yang deficiency (16 times, 3.03%), and blood deficiency (1 times, 0.19%). As for excess in superficiality, blood stasis (129 frequency, 24.4%) and phlegm turbidity (125 frequency, 23.7%) were the most common, which were followed by heat accumulation (42 frequency, 7.95%), water drinking (2 frequency, 0.38%). According to the syndrome diagnosis analysis of the combination of syndrome elements, 220 cases (83.65%) had single syndrome differentiation, 42 cases (15.97%) had two syndromes at the same time, and 1 case (0.38%) had three syndromes at the same time. Among all the syndrome types, Qi deficiency and blood stasis syndrome (94 cases, 42.7%) was the most common, which were followed by phlegm and blood stasis syndrome (46 cases, 20.9%), Qi and Yin deficiency syndrome (41 cases, 18.6%) and heart and kidney deficiency syndrome (32 cases, 14.6%). And Yang deficiency and water flooding syndrome (6 cases, 2.73%) and heart fire blazing syndrome (1 case, 0.45%) were relatively rare. According to the distribution regularity of syndrome, traditional Chinese medicine therapies were mainly for tonifying vital qi and protecting kidney Qi, with equal emphasis on removing phlegm, eliminating dampness and diuresis, activating blood circulation and removing blood stasis. Conclusion:The pathogenesis of NSTEMI is deficiency in origin and excess in superficiality. Deficiency in origin is mostly Qi deficiency and Yin deficiency, while excess in superficiality is mostly blood stasis, phlegm and heat accumulation. traditional Chinese medicine therapies are mostly for invigorating Qi and nourishing Yin, promoting blood circulation and removing blood stasis, clearing heat and resolving phlegm.
