冠心病心绞痛(气虚血瘀证)症状疗效评分量表的研究

目的:建立冠心病心绞痛(气虚血瘀证)症状疗效评分量表。方法:症状评分与其发生率(频率)、重要性(专家评定)及严重性(轻中重)有关,根据以上3种因素(因子)的症状评分数学模型,形成冠心病心绞痛(气虚血瘀证)中医症状的评分量表,通过信度、效度、反应度的评价,确认其可行性和合理性。结果:6个症状(胸痛、胸闷、心悸、气短、神疲乏力、唇色紫暗)作为疗效评分症状群,根据其发生率、重要性和严重性确定了各自权重因子和量表等级分值。信度结果可靠,一致性良好,反应灵敏。结论:冠心病心绞痛(气虚血瘀证)中医症状疗效评分量表,可为此类临床研究提供一个应用工具。

Study of the symptoms scale for evaluating changes in patients with coronary angina pectoris and Qi-deficiency combined with stagnation of blood in traditional Chinese medicine

AIM: To develope a symptom scale for evaluating efficacy of coronary angina pectoris and Qideficiency combined with stagnation of blood.METHODS: The symptom score is always related with its incidence rate (frequency), its importance (evaluated by experts)and its serious degree (light, moderate and serious) in a measuring scale, and a mathematical model was used to calculate the weight factor and its score for each symptom in the scale.In an example of coronary angina pectoris and Qi-deficiency combined with stagnation of blood trial was analyzed based on the scale, and the scale was evaluated with the reliability, the validity, and the responsibility to change.RESULTS: Six symptoms (chest pain, chest distress, palmus, short breath, debilitation, and cyanosis)were selected as indices, and their weight factors and grades were calculated in a score scale.Some evaluations demonstrated that the approach showed a better feasibility, uniformity, and responsibility to change.CONCLUSION: This scale can be used to evaluating the efficacy of coronary angina pectoris and Qi-deficiency combined with stagnation of blood in traditional Chinese medicine.
