高血脂是指體內血液中脂肪量過高，雖然於症狀輕微時，只會稍微不適，但當患者沒有好好控制放任其發展，症狀嚴重時甚至會引發腦血管疾病或心臟疾病而導致死亡，高血脂患者根據行政院衛生署之研究[2-3]，在2013年時高血脂患者已高達432萬人，是一種很常見之疾病。
高血脂能引起動脈粥樣硬化[4-6]，動脈粥樣硬化為一種血管阻塞之疾病，當導致阻塞心臟血管或腦部動脈可能導致缺血性腦中風或心臟衰竭造成患者死亡，因此如何治療高血脂以避免得到動脈粥樣硬化為有意義之研究，目前治療高血脂方式為服藥，大部分患者服用西藥，然而卻有研究指出降血脂藥物有不少副作用對肝，肌肉，胃有不良影響 [7-10]，有研究[21-25]指出部分中藥確實有療效，因此有部分患者改為使用中藥治療，雖然高血脂和動脈粥樣硬化有關，然而卻無針對高血脂患者服用中藥預防動脈粥樣硬化之研究。
本研究目的為評估服用中藥治療高血脂是否有助於避免得到動脈粥樣硬化，由全民健保資料庫共1,000,000人中，搜尋1996年到2005年間被診斷出高血脂患者共120768人，進一步搜尋一年內有三次以上看診紀錄或一次住院紀錄之患者69218人，再排除有糖尿病或高血壓患者共46256人，更進一步排除得到高血脂前已經有動脈粥樣硬化患者共1178人，最終獲得高血脂患者共21984人，將其區分為，僅服用中藥治療、服用中藥和西藥治療及僅服用西藥治療，並追蹤至2010年，結果顯示僅服用中藥高血脂患者僅有3.52%機率得到動脈粥樣硬化，和另外兩組18.38%及16.62%相比，其結果明顯低。本研究又更進一步針對性別、年齡、居住區域等進行分析和統計，亦就僅服用中藥患者所服用之中藥種類進行根據使用次數排名進行分析和統計，其能協助高血脂患者降低得到動脈粥樣硬化之機率。

Hyperlipidemia corresponds to abnormally elevated levels of lipids or lipoproteins in the blood. Hyperlipidemia is the most important risk factor for atherosclerosis [4-6]. Atherosclerosis is a disease in which plaque builds up inside your arteries. . If the disease is not properly controlled, atherosclerosis can further cause other death-causing cardiovascular diseases such as ischemic stroke or heart failure. In light of the association between hyperlipidemia and Atherosclerosis, the study regarding the risk of getting atherosclerosis under different treatment methods of hyperlipidemia is meaningful. This paper aims at evaluating the effectiveness of TCM drugs in treating hyperlipidemia to prevent the risk of getting atherosclerosis. The result shows that till 2010, a surprisingly low 3.52% hyperlipidemia patients in the TCM-only group later developed into atherosclerosis, in contrast with 14.52% and 14.48% in the mixed-usage and western medicine-only ones, respectively. If further stratified according to gender, age, and area. The specific drugs prescribed are also ranked according to the number of usage, average prescription period, and dosage in the hope that the risking of developing into atherosclerosis for patients with hyperlipidemia can be effectively lowered through this study.
