基于因子分析的稳定型心绞痛证候要素研究

目的 探讨稳定型心绞痛证候要素,为该病的辨证论治提供依据.方法 设计前瞻性观察方案,选取经冠脉造影证实的251例冠心病心绞痛患者,观察其中医症状特点,通过因子分析提取证候要素并对其分布情况进行分析.结果 因子分析结果得出6个公因子(证候要素),其分布情况为血瘀占37.8%,气虚占33.1%,痰浊占16.7%,阴虚占12.4%.结论 稳定型心绞痛主要证候要素是血瘀、气虚;次要证候要素为痰浊、阴虚;病位在心,主要涉及肾、脾两脏.

Study on Syndrome Elements of Stable Angina Pectoris Based on Factor Analysis

Objective To investigate the syndrome elements of stable angina pectoris(SAP)to provide objective evidence for syndrome differentiation and treatment.Methods A prospective observation was done on 251 SAP patients confirmed by coronary angiography.The characteristics of TCM symptoms and syndrome distribution were summarized with factor analysis to abstract the syndrome element.Results There were 6 common factors(syndrome element)picked up by the factor analysis.The distribution of syndrome element among the 251 patients were as follows:blood stasis occupying 37.8%,qi deficiency occupying 33.1%,phlegm occupying 16.7%,and yin deficiency occupying 12.4%.Conclusion The major syndrome elements of SAP were blood stasis and qi deficiency.The secondary ones were phlegm and yin deficiency.The location of disease was in heart,mainly with kidney and spleen involved.
