【摘要】 目的:探讨冠心病性无痛性心肌缺血(SMI)发作规律。方法:对确诊的冠心病人486例,进行24hHolter监测,观察SMI发作,分析发作次数、时间与预后的关系。结果:监测中记录到SMI335人698次,累计时间为3526min,其中619次(88.7％)与活动有关。6:00～12:00am为SMI发作高峰,此期间发作次数为389次,累计时间为2100min。具有SMI的冠心病患者的死亡率明显高于有症状冠心病患者。结论:SMI存在并且有一定的发作规律,对于指导临床治疗、降低心脏猝死及缺血性心肌病的发生有一定参考价值。更多还原

【Abstract】 Objective: To study the attack features of silent myocardial ischemia (SMI) in patients with coronary artery disease. Methods:486 cases with coronary heart disease were monitored by Holler for 24 h to observe the attack law of SMI and analyse the relationship between frequency, time of the attack and the prognosis. Results: It was found that there were 335 cases(698 times) with SMI.The whole time was 3526 minutes.619 times of attacks (88.7%) were related with physical exetion.The attack peak of SMI was from 6:00 to 12:00am (389 times,2100 minutes in all) .The death rate of the cases with SMI was higher than that without SMI. Conclusion: SMI attack has some law, which has referance value for guiding clinic treatment and reducing rate of heart sudden death and attack of ischemic cardionyopathy.更多还原
