About

Investigators adopt cross-sectional study design to carry out the exemplary research in the aspects of disease diagnosis.This study is designed to confirm the hypothesis "acupoint sensitization is associated with a severity of angina pectoris, which may contribute to the diagnosis of stable angina pectoris". After the eligible participants recruited in group, the coronary artery lesions will be evaluated through coronary angiography and the Canadian Cardiovascular Society(CCS) angina pectoris classification will also be evaluated at the same time. The degree of acupoint sensitization will be tested by the electronic Von Frey instrument by one professional acupuncturist with total 12 acupoints, including Shenmen,Yinxi, Shaohao,Jiquan,Neiguan, Ximen, Quze, Shanzhong, Juque, Jueyinyu, Xinyu, Duyu. Analysis were conducted to explore relationships between the degree of acupoint sensitization, the degree of coronary artery stenosis and CCS angina pectoris classification. Diagnostic value will be further analyzed in the final step.
