Clinical Retrospective Study of Distribution of TCM Syndrome for Elderly Hypertension

Objective To analyse the distribution and evolution law of TCM syndrome for elderly hypertension (EH), to provide evidence for syndrome standardization study. Methods Case history of 2 029 EH patients during recent ten years were investigated in the way of epidemiology. The main and complicated syndrome types were studied. Results The main syndrome types of EH were yin deficiency of liver and kidney (40.0%), kidney qi deficiency (28.4%), hyperactivity of liver-yang (9.7%), excessive accumulation of phlegm-dampness (7.4%), collateral obstruction by blood stasis (6.6%), phlegm and blood stasis (5.7%), liver-fire hyperactivity (1.1%). The complicated syndrome types were liver-fire hyperactivity (26.5%), excessive accumulation of phlegm-dampness (9.6%), collateral obstruction by blood stasis (7.2%), phlegm and blood stasis (5.5%), kidney yin deficiency (3.7%). Conclusion The distribution of EH TCM syndrome is mainly about deficiency syndromes, in which kidney qi deficiency syndrome is very common, and mostly complicated with phlegm and blood.
