摘要
目的:评价应用动态心电图(Holter)诊断心肌缺血总负荷(TIB)的方法筛查无痛性心肌缺血(SMI)的临床价值。方法:对112例有冠心病危险因素但无胸痛主诉的体检者,常规行Holter检查,评价其TIB,对达标者(TIB≥60mm.min.24h-1)进一步行冠状动脉造影检查,同时对冠状动脉血管病变的程度进行Gensini积分评价,并行相关性分析。结果:42例(42/112)提示有TIB达标。对其中38例(38/42)进行了冠状动脉造影检查,29例(76.3%)经造影确诊为冠心病,9例(23.7%)造影无明显异常。相关性分析表明TIB的大小与冠状动脉血管病变的程度呈正相关(r=0.749,P<0.01)。结论:Holter诊断TIB的方法可以较为客观地评价心肌缺血的程度,对于冠心病患者特别是SMI的检出有一定的价值。
Objective：To evaluate the role of total ischemia burden （TIB） diagnosed by dynamic electrocardiograph in patients with silent myocardial ischemia （SMI）. Method：The total of 112 patients with coronary dangerous factors but without chest pain were collected, and underwent dynamic electrocardiograph which was used to evaluate the TIB. Coronary angiograph（CAG） was need to those who had the positive result （TIB≥60 mm · min · 24 h^-1）while Gensini cumulative index of coronary artery was evaluated. Result：Of 112 cases, 42 cases attended the criterion of TIB, and 38 of 42 patients had CAG examination. The 29 of 38 cases were diagnosed as coronary heart disease by CAG; the other 9 cases had no positive results. There was positive correlation between the levels of TIB and Gensini cumulative index（r= 0. 749, P〈0. 01 ）. Conclusion： TIB in dynamic electrocardiograph could estimate the existence and extent of myocardial ischemia objectively, which assists to diagnose coronary heart disease, especially SMI.
