Objective Based on the theory of endogenous collateral wind, this study aims to compare the differences of eye collaterals between stable coronary heart disease (CHD) patients and non-CHD patients, to investigate the relationship between shape-and-color characteristics of eye collaterals and stable CHD, and to provide evidences for CHD treatment with the theory of endogenous collateral wind.Methods 68 stable CHD patients and 30 non-CHD patients as control were enrolled. Eye collaterals around the iris around at least 8 mm were captured and digitized using camera, and shape-and-color characteristics of eye collaterals were evaluated. Combined the theories of obstruction of collaterals and invasion of collaterals by evil wind, correlation between endogenous collateral wind and CHD were investigated.Result There was significant difference of color intensity of eye collaterals between CHD group and non-CHD group (P<0.05). There were also statistical differences between the two groups in the length of the collaterals, the thickness of the collaterals, the radius of curvature, the curvature and the area of the collaterals (P<0.05).Conclusion The shape-and-color characteristics of eye collaterals were correlated with stable CHD, may be used for prediction and evaluation of CHD.%目的 基于络风内动病机学说,从"络脉为病"角度切入,对比分析稳定性冠状动脉粥样硬化性心脏病(冠心病)与非冠心病患者目睛络脉的不同特点,探究目睛络脉形色特征与稳定性冠心病之间的相关性,为临床"从络从风论治"冠心病提供客观依据.方法 入选68例稳定性冠心病患者,同时选取30例非冠心病人群作为对照,两组患者在年龄性别方面无统计学差异,具有可比性,锁定眼球巩膜上下左右四个方向暴露的表面络脉,利用专业相机对环绕虹膜周围至少8 mm距离范围内的目睛络脉进行影像采集及数字化处理,并对络脉形色特征进行客观评价,同时结合中医络脉瘀阻、风邪袭络理论进行对比分析,探讨络风内动病机与冠心病之间的相关性.结果 稳定性冠心病组目睛络脉明暗色彩度与非冠心病组相比差异明显(P<0.05),两组在络脉长度极值、络脉粗细、大小弯半径、弧度和络脉面积等方面也具有统计学差异(P<0.05).结论 目睛络脉与稳定性冠心病之间具有一定相关性,间接证实络风内动是稳定性冠心病的基本病机之一,通过目睛络脉形色特征可在一定程度上对冠心病进行预测和评价.
