[Abstract] Objective To investigate the effect of nicorandil on endothelial-dependent flow-mediated vasodilation(FMD) of the brachial artery in patients with coronary slow flow(CSF). Methods 120 patients with CSF were enrolled and randomized divided into control group(n=60)and nicorandil group(n=60). Control group patients were administrated of conventional treatment,nicorandil group were administrated of nicorandil on the basis of conventional treatment. The levels of FMD,APN,hsCRP were measured before and three months after treatmeat. Results Compared with before treatment,FMD improved in nicorandil groups after treatment(P<0.05),APN level increased(P<0.05) whereas hs-CRP level decreased(P<0.05);changes of FMD was positively correlated with changes of APN,and was negativly correlated with changes of hs-CRP. FMD,APN and hs-CRP in control group had no significantly changes after 3 months' treatment. Conclusion Nicorandil can improve the FMD of the brachial artery in patients with CSF.

冠狀動脈慢血流(CSF)是指排除冠狀動脈痙攣、血栓、冠狀動脈擴張等因素,冠脈造影(CAG)沒有發現明顯病變,但冠脈血流減慢的現象[1]。其發病機制不明確,亦缺乏有效的治療方法。本研究通過檢測治療前后CSF患者肱動脈血流介導的內皮依賴性血管舒張功能(FMD)、血漿hs-CRP及脂聯素(APN)水平,觀察尼可地爾對CSF治療效果。
1 對象與方法
1.1 研究對象
2011年4月~2013年4月于我院心內科因心絞痛行CAG并診斷為CSF的患者120例,隨機分為兩組,尼可地爾組60例,男39例,女21例,年齡(53.14±9.10)歲;對照組60例,男36例,女24例,年齡(52.20±10.34)歲,入選患者
均排除冠狀動脈異常擴張、冠狀動脈夾層、肝腎功能不全、心衰。對照組給予常規冠心病藥物治療(硝酸酯類、阿司匹林、他汀類等),尼可地爾組在常規治療基礎上加服尼可地爾(5 mg,3次/d),隨訪時間為3個月。
