基于层次分析法对冠心病痰瘀互结证辨证依据重要性评估探讨

目的]基于层次分析法对冠心病痰瘀互结证的各大症状进行重要程度评价。方法]在全国范围内,开展3轮层次分析法专家咨询,计算冠心病痰瘀互结证各诊断要素的权重系数。结果] 3轮咨询共回收有效问卷81份,第一轮回收3份问卷,第二轮回收19份问卷,第三轮回收59份问卷,回收率为100%。经统计,一级指标的权重由高到低依次为临床症状、舌象、脉象。二级指标权重由高到低依次为胸闷胸痛、舌质紫暗、苔腻、舌有瘀斑瘀点、脉弦滑、舌下络脉青紫、脉弦涩、体胖、唇青紫、面色晦暗、口黏、肢体困重。结论]以冠心病痰瘀互结证为范例,探索基于层次分析法研究证候辨证依据的权重,为进一步研究冠心病痰瘀互结证宏观诊断标准提供依据,具有一定的临床意义。

Preliminary assessment based on analytic hierarchy process on the importance of syndrome differentiation basis of intermingled phlegm-blood stasis syndrome in coronary heart disease

Objective] Preliminary assessment based on analytic hierarchy process on the importance of syndrome differentiation basis of intermingled phlegm-blood stasis syndrome in coronary heart disease.Methods] Three rounds of the modeling symptom quantitative evaluation of the importance of syndrome differentiation basis of phlegm syndrome in coronary heart disease was constructed. The weight coefficient of each diagnostic factor was calculated by analytic hierarchy process.Results] The 81 questionnaires were recovered in three rounds of consultation,3 experts were consulted in the first round,19 experts were consulted in the second round and 59 experts were consulted in the third round. The recovery rate of 100%. According to statistics,rank of contribution weight of primary indicators from high to low as follows:clinical symptoms,tongue,pulse. Contribution weight of secondary indicators from high to low as follows:chest tightness/chest pain,purple tongue,greasy coating,tongue with petechia or bruise,stringtaut and slippery pulse,bluish and purplish sublingual vessels,wiry and choopy pulse,obesity,bluish lips,gloomy complexion,sticky mouth,heaviness of limbs.Conclusion] The study took the intermingled phlegm-blood stasis syndrome in coronary heart disease as an example to discuss the syndrome differentiation based on analytic hierarchy process. It has certain clinical significance to research macroscopical diagnostic criteria of intermingled phlegm and blood stasis of coronary heart disease.
