6.冠状动脉痉挛防治展望 CAS发病率很高,临床表现复杂,难以完全识别,临床关注不够。因其发病机制不很清楚,致使其防治药物选择受限。吸烟是CAS的重要危险因素[8]。防治中特别强调忌烟戒酒,同时控制高血压、糖尿病、高血脂及肥胖等危险因素[9]。CAS防治目前主要药物是CCB和NO供体制剂,能一过性缓解痉挛,但远期疗效不确切。Rho激酶抑制剂法舒地尔1997年用于治疗蛛网膜下腔出血导致的脑血管痉挛。据报导法舒地尔可明显减轻乙酰胆碱诱发的冠状动脉痉挛,对稳定性心绞痛,微血管性心绞痛有明确疗效[10,11]。Rho激酶有可能成为防治冠状动脉痉挛心绞痛有前途的药物。我们承担国家重点基础“973”项目的实验证明:中医药通络方剂有明确的抑制血管痉挛的作用[12-14],并探讨了其作用机制,中医药防治冠脉痉挛具有广泛的前途。但需要深入的研究。
