适度告知对冠脉严重狭窄病人心肌缺血事件的影响

The Effect of Moderate Informing about Severe Stenosis on the Occurrence of Myocardial Ischemic Event

目的 探讨适度告知对冠状动脉病变严重狭窄病人的心肌缺血事件的影响。 方法 将实施冠状动脉造影后示多支多处严重狭窄需进d一步治疗的 10 5例病人随机分为观察组 (5 3例 )和对照组 (5 2例 ) ,观察组只告知冠脉有病变 ,不告知具体病变血管支数和狭窄程度 ,对照组被告知冠状动脉造影真实结果 ,两组均将造影所示结果告知病人家属。观察并比较两组病人造影术后 4h焦虑值及 3d内心肌缺血发生情况。 结果 观察组焦虑值及心肌缺血事件发生率均低于对照组 (P <0 .0 1)。

Objective To investigate the effect of moderate informing about severe of stenosis on the occurrence of myocardial ischemic event in patients with severe polystenosis of coronary artery. Methods 105 patients with severy polystenosis of coronary artery verified by coronary arteriography(CAG) were divided randomly into two groups, treat group (n=53) and control group (n=52). Patients of control group were informed in detail about the result of CAG ,those of treat group were moderately informed about having artery stenosis,but no details. Anxious value was detected at the end of the 4th hour after CAG and all myocardial ischemic events were recorded during the 3 days after CAG. Result Anxious values and occurrence of myocardial ischemic event in the treat group were significantly less than the control one(P<0.05). Conclusion The moderate infoming about severe of stenosis can decrease the occurrence rate of myocardial ischemic events after CAG in patients with severe polystenosis of coronary artery.
