本研究的目的在了解台灣原發性高血壓患者的中醫體質概況。依據中醫體質分型方法對高血壓患者進行分類，並收集其血壓、質量指數與相關之各項實驗生化值。結果發現高血壓病患除正常質（43.6%）外，以陰虛質（33.3%）、痰濕質＋濕熱質（29.8%）此兩組病理性體質所佔比例較多，不同體質間其血壓變異數、左心室質量指數、三酸甘油脂、高密度脂蛋白、低密度脂蛋白並無顯著差異。此外，在接受藥物治療下仍無法回復到正常收縮壓值內（低於140mmHg）則以陽虛質（75%）與氣虛質（60%）最多。於此101例原發性高血壓病患中發現，即使不同體質患者，在接受合適的降血壓藥物下，血壓波動的情形可控制在一定範圍內，而靶器官損害的機率也可能因此減低。The objective of the study is to understand the constitutional situation of the patients with primary hypertension in Taiwan. 101 patients with primary hypertension and related blood pressure, left ventricle mass index and estimated biochemical values were classified according to the constitutional analysis. The results showed ying defecicency and tanshi were in the proportion of 33.3% and 29.8% respectively among the primary hypertension patients. There were no significant difference in variability of blood pressure, LV mass index, TG, HDL and LDL among the different constitutional features. Besides, yang defecicency (70%) and Qi defecicency (60%) were found in the hypertensive patients with poor controlled systolic blood pressure. The target organ damage of the hypertensive patients could be reduced with the adequate medication in the different contitutional features. In summary, it is the first time in Taiwan that we try to study the the constitutional situation of the patients with primary hypertension. However, the results are not corresponding to our expectation, the long term observation and a lager group of patients are needed for further researches.
