摘　　要：目的探讨aVR导联ST段抬高对冠心病患者冠脉狭窄支数、受累血管部位及心脏事件的发生率的影响并进行观察。方法方便选取2016年11月—2017年11月在该院接受治疗的86例冠心病患者作为此次研究对象,将aVR导联ST段正常患者作为对照组,将aVR导联ST段抬高患者作为研究组,对比两组患者冠脉狭窄支数、研究组患者受累血管部位和两组患者心脏事件发生情况。结果研究组冠脉狭窄支左前降支38(95.0%)、左主干15(37.5%)及三支32(80.0%)的发生率高于对照组,而单只2(5.0%)和双支3(7.5%)的冠脉狭窄发生率则低于对照组(χ~2=29.400、4.420、22.960、12.694、21.384,P<0.05);研究组依据相关导联ST段压低可以分为侧壁压低患者21例、下壁压低患者11例和前壁压低患者26例,3种患者的LAD(左前降支)、LCX(左回旋支)和RCA(右冠状动脉)血管狭窄的发生率差异无统计学意义(P>0.05);对照组心脏事件发生率为13.0%,研究组心脏事件发生率为95.0%,研究组心脏事件发生率高于对照组(χ~2=57.515,P<0.05)。结论 aVR导联ST段抬在相关血管判定中有着以为重要的价值,提示患者左前降支、左主干及多支发生病变,而且aVR导联ST段抬高患者心脏事件的发生几率较高,预后情况差。Objective To investigate the effect of ST segment elevation in aVR lead on coronary stenosis, involvement of vascular sites and incidence of cardiac events in patients with coronary heart disease. Methods 86 patients with coronary heart disease who were treated in the hospital from November 2016 to November 2017 were convenient enrolled in this study. The patients with ST segment of aVR lead were used as control group, and patients with ST segment elevation in aVR lead were used as the study group. In the study group, the number of coronary stenosis in the two groups, the affected vas- cular site in the study group, and the cardiac events in the two groups were compared. Results The incidence of left anterior descending coronary artery stenosis 38 （95.0%）, left main trunk 15 （37.5%） and three branches 32 （80.0%） in the study group was higher than that in the control group, while only 2 （5.0%） and double branches incidence of coronary stenosis was lower in 3 （7.5%） than in the control group （X2=29.400, 4.420, 22.960, 12.694, 21.384, P〈0.05）. The study group could be divided into patients with lateral wall depression according to the ST-segment depression of the relevant lead. There were 21 eases, 11 eases of inferior wall depression and 26 eases of anterior wall depression. There was no significant difference in the incidence of vascular stenosis between LAD （left anterior descending）, LCX （left circm^Lflex） and RCA （right coronary artery） in three patients （P〉0.05）; the incidence of cardiac events in the control group was 13.0%, and the incidence of car- diac events in the study group was 95.0%. The incidence of cardiac events in the study group was higher than that in thecontrol group （X2=57.515, P〈0.05）. Conclusion The ST segmental elevation of aVR leads has important value in the deterruination of related vessels, suggesting that patients with left anterior descending, left main and muhiple branches have a higher incidence of cardiac events in patients with ST-
