[Maximal Frequent Association Patterns between Symptoms of Coronary Heart Disease Patients with Blood Stasis Syndrome and Medication Constitutions].

A total of 121 medical cases concerning treating coronary heart disease (CHD) pa- tients with blood stasis syndrome (BSS) by Chinese Medicine were collected to establish a database for CHD patients with BSS. By using data mining authors tried to explore inherent laws of its symptoms and medication of Chinese Medicine, and to probe maximal frequent association patterns between its symp- toms and medication constitutions. Of the 121 medical cases, chest pain, chest stiffness, and headache were their common symptoms. Compatibilities of blood-activating drugs, stasis-resolving drugs, and qi- promoting drugs were most commonly used. The association between symptoms and compatibilities con- stituted a most often seen maximal frequent association pattern, which reflected an idea of treating both principal and subordinate symptoms.
