急性心肌梗塞发病急,病死率高,危害性较大。如能动态观察病情变化,对预后做出正确判断可减少并发症,降低病死率。尽管依靠病史、心电图、心肌酶测定等手段对临床帮助很大,但对急性心肌梗塞(AMl)预后的判断尚有一定的局限性。我们利用心脏收缩时间间期(STI)测定这种无创伤心功能检查法对24例AMI后患者进行STI测定,并动态观察其心功能变化。结果表明,STI对判断AMI的预后有很大的临床价值。现报告如下: 1 观察对象 本文24例住院患者,其诊断依据符合世界卫生组织(WHO)诊断标准;其中男15例,女9例,平均年龄59.25±3.7岁。梗塞范围包括前壁6例,前间壁2例,广泛前壁2例,下壁7例,下后壁2例,高侧壁2例,下壁梗塞并前壁ST段压低5例。其中并心律失常8例,心力衰竭5例。本文主要测定住院患者(梗塞后4周)的STI变化。
Acute myocardial infarction acute onset, high mortality, more harmful. If the dynamic observation of changes in condition, to make a correct prognosis to reduce complications and reduce mortality. Although the clinical history, ECG, myocardial enzyme determination and other means of clinical help, but the prognosis of acute myocardial infarction (AMl) to judge there are some limitations. We performed STI determination of 24 patients with AMI using this noninvasive cardiac function test by systolic time of heart systole (STI) and their changes in cardiac function were observed dynamically. The results show that, STI to determine the prognosis of AMI has great clinical value. The report is as follows: 1 observed objects 24 hospitalized patients, whose diagnostic criteria in line with the World Health Organization (WHO) diagnostic criteria; including 15 males and 9 females, mean age 59.25 ± 3.7 years old. The infarct range includes 6 cases of anterior wall, 2 anterior wall, 2 extensive anterior wall, 7 inferior wall, 2 inferior posterior wall, 2 superior wall, inferior wall infarction and anterior ST segment depression in 5 cases. Of which 8 cases of arrhythmia, heart failure in 5 cases. This article measures the STI changes in hospitalized patients (4 weeks after infarction).
