| | 制药论文[摘 要] 目的制药论文:为探讨冠心病无症状性心肌缺血的制药论文动态心电图(DCG)的临床特点。方法:对582例冠心病患者进行DCG监测。结果:402例有3 884阵次缺血发作,其中307例2 930阵次(75.44%)为无症状性心肌缺血(SMI),其中60岁以上者发作2 135阵次,占SMI的72.87%,无症状与有症状组心肌缺血的ST段压低程度差异无显著性,但无症状较有症状组心肌缺血持续时间长(P<0.05)。上午6:00~12:00 SMI的发作频率最高(43.46%),明显多于夜间24:00~晨6:00的13.62%(P<0.01)。检出严重心律失常共327例,无症状与有症状组之间差异无显著性(P>0.05)。结论:SMI检出率远高于有症状心肌缺血,60岁以上者多见,容易引起患者忽视而得不到及时治疗,因此,更具有潜在危险,在诊治上应给予高度重视。 [关键词] 冠心病;无症状性心肌缺血;动态心电图 Exploration of DCG in Coronary Heart Disease with SMI ZUO Jingsheng (Chen Xing Hai Hospital of Zhongshan City, Zhongshan,Guangdong 528415, China) Abstract:Objective To probe into the clinical features of theDCGin coronary heart disease with SMI .Methods 24h DCG detection for 582 patients with CHD .Results There are 3884 ischemic heart conditions attack in 402 patients ,in which 2930 in 307 patients are SMI (75.44%),and patient above 60 have SMI are 2135, that,s 72.87% in SMI .The low level ST in SMI and ischemia without symptoms has no apparent differences ,but ischemic heart conditions last for longer time in SMI (P<0.05) .SMI attack frequency is higher in 612am (43.46%),that,s obviously higher than in 06am 13.62%(P<0.01).Serious arrhythmia in SMI and ischemia with symptoms have no obvious differences (P>0.05) ,and is 327 cases in total .Conclusion The inspection of SMI is much more than ischemia with symptoms ,and is frequently in people above 60.It,s easy to ignore by the patients so that they can,t treat it in time .Therefore, it has potential danger ,so we should take great attention on it when we make a diagnosis and give treatment . Key word :Coronary heart disease;Silent myocardial ischemia;Dynamic Electrocardiogram 无症状性心肌缺血(SMI)是近年来冠心病防治的重点之一,由于发作隐匿,易被患者忽视,不少冠心病患者发病或猝死前可毫无症状,故SMI应引起临床高度重视,动态心电图(DCG)是检测SMI重要方法之一,对评估SMI的预后有重要意义。本文通过对582例冠心病患者进行24 h动态心电图监测,探讨SMI DCG改变及其临床意义。 1 资料和方法 1.1 一般资料 选择我院1993年1月至2005年1月住院及门诊患者共582例,经临床诊断为冠心病(符合1979年国际心脏病学和WHO诊断标准)。男395例,女187例,年龄37岁~83岁,平均年龄53.1岁,剔除静息心电图有左室肥厚、束支传导阻滞、重度贫血、严重电解质紊乱或洋地黄药物影响的ST段移位者。根据临床特征分为心绞痛型376例,心肌梗死型206例(陈旧性心肌梗死199例,心肌梗死恢复期7例)。
