12导联动态心电图ST段及最大ST/HR在冠心病诊断中的应用价值(1)
[摘要]目的 探讨12导联动态心电图ST段及最大ST/HR在冠心病诊断中的价值。方法 选取2016年2月～2018年2月我院收治的156例冠心病患者作为冠心病组，另选取100例非冠心病患者作为对照组，观察两组患者的12导联动态心电图ST段压低、最大ST/HR情况。根据冠脉造影结果将冠心病患者分为单支病变组(80例)和多支病变组(76例)，观察不同病变的冠心病患者12导联动态心电图ST段压低、最大ST/HR情况。结果 冠心病组的ST段压低、最大ST/HR异常比例均高于对照组，多支病变组冠心病患者的ST段压低、最大ST/HR异常比例明显高于单支病变组，差异均有统计学意义(P<0.05)。结论 12导联动态心电图ST段及最大ST/HR对冠心病诊断有很高的价值，值得临床推广应用。

[Abstract] Objective To discuss the value of ST and maximum ST/HR in diagnosis of coronary heart disease by 12 lead dynamic electrocardiogram. Methods A total of 156 cases of coronary heart disease patients treated in our hospital from February 2016 to February 2018 were selected as coronary heart disease group， and 100 cases without coronary heart disease patients as control group. The ST depress， maximum ST/HR of the two group diagnosed by 12 lead dynamic electrocardiogram were observed， and the coronary heart disease patients were divided into single lesion group (80 cases) and multiple lesions group (76 cases) according to coronary angiography result. The ST depress， maximum ST/HR of different lesions coronary heart disease patients diagnosed by 12 lead dynamic electrocardiogram were observed. Results The ST depress rate and abnormal rate of maximum ST/HR in the coronary heart disease group were higher than those in the control group， the ST depress rate and abnormal rate of maximum ST/HR in the multiple lesions group coronary heart disease patients were higher than those in the single lesion group， and the differences were statistically significant (P<0.05). Conclusion The ST and maximum ST/HR in diagnosis of coronary heart disease by 12 lead dynamic electrocardiogram has high value， which is worthy of clinical popularization and application.

近年来，随着我国心血管疾病发生率逐步升高，冠心病发生率和死亡率也逐年升高，给人们的身心健康造成严重的影响[1-2]。冠心病主要是冠状动脉粥样硬化造成的冠脉管腔狭窄、阻塞，进而发生心肌细胞缺血、缺氧，甚至坏死，危及患者的生命安全[3-4]。及早、准确的诊断对于提高冠心病患者诊断的阳性率、探讨冠状动脉病变严重程度、指导临床治疗、提高患者预后具有重要的临床意义[5-6]。冠脉造影是诊断冠心病的金标准，其准确度较高，但是其属于有创性检查，患者检查的依从性相对较差。心电图属于无创性检查，重复性较高，但是其诊断的准确率一直备受争议。本研究选取156例冠心病患者与100例非冠心病患者作为研究对象，旨在探讨12导联动态心电图ST段及最大ST/HR在冠心病诊断中的价值，现报道如下。
1资料与方法
1.1一般资料
选取2016年2月～2018年2月我院收治的156例冠心病患者作为冠心病组，其中男90例，女66例；年龄56～79岁，平均(67.8±4.8)岁；病程3～l2年，平均(5.7±2.2)年。另选取同期的100例非冠心病患者作为对照組，其中男61例，女39例；年龄55～78岁，平均(66.4±4.5)岁。两组患者的一般资料比较，差异无统计学意义(P>0.05)，具有可比性。根据冠脉造影结果将冠心病患者分为单支病变组(80例)与多支病变组(76例)。单支病变组中，男45例，女35例；年龄55～77岁，平均(66.4±4.2)岁；病程3～l1年，平均(5.2±2.1)年。多支病变组中，男38例，女38例；年龄57～78岁，平均(67.8±4.9)岁；病程3～l3年，平均(5.9±2.5)年。两组患者的一般资料比较，差异无统计学意义(P>0.05)，具有可比性。纳入标准：冠心病患者均通过心电图、冠脉造影及临床症状进行确诊，均签署知情同意书后参与本研究。排除标准：心肌梗死、心肌炎、心脏瓣膜病及左心室肥厚者；快速性心律失常、束支传导阻滞等心电图异常明显者。本研究已经医院医学伦理委员会审核批准。, 百拇医药(李晖 苏鸣)
