2013 ESC Guideline on Management of Stable Coronary Artery Disease redefined the pathogenesis of stable coronary artery disease（ SCAD）. The guidelines pointed out that coronary artery microcirculatory disturbance or arteriospasm was an important cause of SCAD. Coronary microcirculation and reperfusion of myocardial cells should be paid close attention. As the mechanism of microvascular dysfunction is not clear so far

many therapies should still be explored

including Chinese medicine. Coronary artery microcirculatory disturbance or arteriospasm is similar to"collaterals dysfunction"in Chinese medicine

with the characteristics of most deficiency

most blood stasis and mostly changeable. Besides

the pathological changes of SCAD is quite like wind syndrome. The authors put forward the internal stirring of collateral wind theory. The authors hold that the blockade of heart vessel is the basic pathogenesis of SCAD and that internal stirring of collateral wind is an important supplement. Blockade of heart vessel and internal stirring of collateral wind interact both as cause and effect and harm the body together. Then acute coronary syndrome and other cardiovascular emergency and severe diseases might be occurred eventually.
