This article was aimed to study the correlation among traditional Chinese medicine (TCM) syndrome elements in the first year after ischemic stroke. Data of TCM four examinations were collected among subjects all over China by cross-sectional study, using the same observing rating scale. The results showed that internal-heat, internal-wind and phlegm-damp syndrome were risk factors with obvious positive correlation. On the contrary, blood-stasis, internal-heat and qi-deficiency syndrome were in obvious negative correlation. But syndrome of yin-deficiency had no significant correlation with other syndrome elements. It was concluded that there were remarkable positive correlations on excess syndromes, such as wind, fire and phlegm. The syndromes of excess in the branch are easily to be combined.
