目的:探究隐匿型冠心病应用十二导联动态心电图的诊断价值。方法:从广东药科大学附属第一医院2013年至2015年间就诊患有冠心病危险因素的患者中选取260例,对其进行十二导联动态心电图检查,将检查结果为阳性患者再进行冠状动脉造影检查,对比两次的检查结果,分析十二导联动态心电图在隐匿型冠心病中的诊断价值。结果:260例行十二导联动态心电图检查的患者中有120例患者诊断为冠心病阳性,在这120例患者行冠状动脉造影检查患者中有85例患者诊断为冠心病,占比70.8%。心肌缺血程度严重患者与心肌缺血程度较轻患者相比,缺血程度严重者其冠脉狭窄≥75%的患者多于缺血程度较轻患者,差异具有统计学意义(P<0.05)。结论:十二导联动态心电图对于隐匿型冠心病具有较高的诊断阳性率,可用于对隐匿性冠心病的初级筛查。
Objective: To investigate the diagnostic value of 12-lead ambulatory electrocardiogram in patients with occult coronary heart disease. Methods: From the First Affiliated Hospital of Guangdong University of Pharmacy from 2013 to 2015, patients with coronary heart disease risk factors were selected 260 cases of their 12-lead dynamic electrocardiogram examination, the test results were positive again coronary Arteriography, compared with two test results, analysis of 12 lead ambulatory ECG in the diagnosis of occult coronary heart disease. Results: Among the 260 patients who underwent 12-lead ambulatory electrocardiography, 120 patients were diagnosed as having coronary heart disease. Among the 120 patients who underwent coronary angiography, 85 patients were diagnosed as coronary heart disease, accounting for 70.8% . Patients with severe myocardial ischemia compared with patients with mild myocardial ischemia, patients with severe ischemic coronary artery stenosis ≥ 75% more patients than those with less severe ischemia, the difference was statistically significant (P <0.05) . Conclusion: The 12-lead ambulatory electrocardiogram has a high diagnostic positive rate for occult coronary heart disease and can be used for primary screening of occult coronary heart disease.
