摘要 他汀类药物是一类治疗高胆固醇血症的有效药物。大量临床研究显示这类药物用于心血管病高危人群可以显著降低患病率和病死率,因此在目前的脂质代谢异常和动脉粥样硬化(AS)疾病治疗指南中被广泛推荐。近年来一系列的大规模临床研究显示了积极降低低密度脂蛋白胆固醇(LDL—C)的治疗在心血管病患者降低临床事件的有效性。目前的治疗指南将LDL—C作为调脂治疗的首要目标。在心血管病极高危患者,甚至可以选择性地将LDL—C降低至1.81mmol/L(70mg/dl)以下。尽管如此,研究发现在高密度脂蛋白胆固醇(HDL—C)显著降低的患者,他汀类药物并不能使临床事件下降到较低的水平。他汀类药物升高HDL.C的幅度仅为5%-10%,对甘油三酯(TG)降低的程度为10%-20%。因此在合并HDL—C降低和(或)TG升高时,他汀类药物并不能全面改善患者的脂质谱。
