Research on relationship between coronary lesion and blood stasis syndrome based on coronary angiography / 中国中西医结合杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the relationship between blood stasis (BS) syndrome and coronary lesion in patients with coronary heart disease (CHD).</p><p><b>METHODS</b>Syndrome types of 500 patients collected from multiple centers whose diagnosis of CHD confirmed by coronary angiography were differentiated. And the relationship between BS syndrome, its subtypes, and coronary lesion (affected branches, degree of constriction) were analyzed.</p><p><b>RESULTS</b>The affected branches of coronary artery in patients of BS syndrome was 2.28 +/- 0.28, while that in the non-BS syndrome patients was 2.07 +/- 0.86, showing significant difference between them (P < 0.05); as compared to patients of non-BS syndrome, the coronary lesions in patients of BS syndrome were mostly multi-vascular, and of more severe degree (P < 0.05). In patients of various BS syndrome subtypes, the average number of affected coronary branches in patients of yang-deficiency subtype was 2.58 +/- 0.65, which was significantly more than the number in patients of other BS syndrome subtypes. The constriction degree of coronary lesions in patients of yang-deficiency BS syndrome subtype were mostly severe or moderate, and single branch lesion was rarely seen, as compared with those in patients of phlegm-stasis obstruction subtype, the difference was significant (P < 0.05). The corresponding correlative analysis showed that close correlation was found between yang-deficiency subtype of BS syndrome and severe coronary constriction with the correlation distance of 0.1899.</p><p><b>CONCLUSION</b>Relationship between BS syndrome and coronary lesion (its number of branches and degree of constriction) truly exists to a certain extent.</p>
