目的 为进一步确定急性心肌梗塞后左室重构发生的时间,以及心肌梗塞对收缩与舒张功能的影响.方法 本研究用彩色多勒超声心动图对58例(164人次)心肌梗塞患者的心脏结构、左室收缩与舒张功能等多项指标进行了追踪观察,按患者心肌梗塞后时间的长短分为7组(1周～>1年).结果 心肌梗塞早期(1周)对心功能有较大影响,主要与心肌缺血、心肌顿抑有关,心肌梗塞后3～6个月心功能有所改善,临床上应尽早使用保护心脏的药物.
Objective To further determine the timing of left ventricular remodeling after acute myocardial infarction and the effect of myocardial infarction on systolic and diastolic function.Methods Color Doppler echocardiography was used to evaluate the cardiac structure of 58 patients with 164 myocardial infarctions , Left ventricular systolic and diastolic function and other indicators were followed up, according to the length of time after myocardial infarction patients were divided into 7 groups (1 week to 1 year) .Results Early myocardial infarction (1 week) on cardiac function Major impact, mainly with myocardial ischemia, myocardial stunning, 3 to 6 months after myocardial infarction improved cardiac function, clinical use of heart protection as soon as possible drugs.
