冠心病中医证候地域性特征的临床流行病学调查

Clinical Epidemiological Investigation on Regional Characteristics of Traditonal Chinese Medicine Syndromes of Coronary Heart Disease

目的分析我国冠心病中医证候的地域性分布特征。方法运用临床流行病学调查方法,对来自东北、华北、华东、华中、华南、西南、西北7大地区的8129例冠心病患者证候要素及证候类型进行分析,总结其差异与规律。结果各个地域最常见的虚性证素均为气虚和阴虚,实性证素均为血瘀和痰浊。血瘀与气虚地域分布特点相似,提示两者可能存在相关性。气虚和血瘀均以东北地区最为多见,痰浊在西南和华南地区最为多见,阴虚在西南和华南地区最为少见,气滞在东北、华北、华东、华中、华南、西北地区相对多见,在西南地区则少见。总体上实性证素严重程度高于虚性证素,呈现出"实重于虚"的特点。结论冠心病中医证候的地域分布存在共性规律,亦有区域特征,有助于指导临床合理地开展因地、因人辨治。

Objective To analyze the regional distribution characteristics of traditonal Chinese medicine(TCM)syndromes of coronary heart disease in China.Methods Clinical epidemiological survey methods were used,syndromes factors and TCM syndrome types of 8129 patients with coronary heart disease from 7 regions in Northeast,North China,East China,Central China,South China,Southwest,and Northwest China were summarized in terms of differences and laws.Results The most common deficiency syndrome factors in all areas are qi deficiency and yin deficiency,and the excess syndrome factors are blood stasis and phlegm turbidity.The geographical distribution of blood stasis and qi deficiency are similar,suggesting a possible correlation between the two factors.Qi deficiency and blood stasis are most common in Northeast China.Phlegm turbidity is most common in Southwest and South China.Yin deficiency is most common in southwest and south China,and qi stagnation is relatively common in Northeast,North China,East China,Central China,South China,and Northwest China,and is rare in the Southwest China.Generally,the severity of excess syndromes is higher than that of deficiency syndromes,demonstrating the feature that excess is higher than deficiency.Conclusion The regional distribution of TCM syndromes in patients with coronary heart disease has common characteristics and regional characteristics.
