心肌梗塞后出现心肌缺血与预后不良有关。近年来,一些研究集中在Ho1ter监测时ST段变化的预后意义上,但均系研究经选择的人群。本文旨在对第一次梗塞后连续病人的出院前Holter监测,评价心肌缺血的存在,证实哪种临床和超声心动图变数,与心肌缺血的发生有最好相关,以其评价其它临床变数对缺血性ST段变化的预后意义。对270例连续心肌梗塞后病人(男214、女56,平均年龄59.7±1岁)作了研究。结果,270例中64例(24%)有缺血性ST段变化,均为无症状性并伴有ST段下移,在非波Q型梗塞中有较高发生率(P<0.01)。大多数ST段变化的病人有室性早搏,在
Myocardial ischemia after myocardial infarction with poor prognosis. In recent years, some studies have focused on the prognostic significance of ST segment changes during Ho1ter monitoring, but all studied selected populations. This article aims to assess the presence of myocardial ischemia after discharge in the first consecutive post-infarction patients with Holter and to determine which clinical and echocardiographic variables are best correlated with the occurrence of myocardial ischemia in order to evaluate other clinical Prognostic significance of variables on ischemic ST segment changes. 270 consecutive patients with myocardial infarction (male 214, female 56, mean age 59.7 ± 1 years) were studied. Results: Of the 270 cases, 64 (24%) had ischemic ST segment changes, both of which were asymptomatic with ST-segment downstaging. There was a high incidence of non-Q-wave infarction (P <0.01). Most ST-segment patients have premature ventricular contractions
