脑梗死是一种致死、致残的常见病。急性脑梗死可以引起患者左心室收缩及舒张功能改变,临床上可出现心律失常,严重者可出现室颤、心源性猝死。急性脑梗死患者心电图异常发生率达72%,主要表现T波低平、ST段下移、病理性Q波、心律失常。通过心脏彩超检查,研究急性脑梗死患者心脏结构与功能改变发现,急性脑梗死与左心室射血分数、心输出量、E/AB比值具有相关性,提示急性脑梗死可引起左室收缩及舒张功能减低。急性脑梗死后发生心电图异常改变,与脑梗死部位有关;心功能异常可能影响脑梗死患者预后。有关左心室功能改变与脑梗死大小、部位,以及与颈动脉硬化及斑块的相关性研究还需要进一步阐明。
Cerebral infarction is a common cause of death and disability. Acute cerebral infarction can cause left ventricular systolic and diastolic changes in patients with clinically arrhythmia, severe ventricular fibrillation may occur, sudden cardiac death. The incidence of ECG abnormalities in patients with acute cerebral infarction up to 72%, the main manifestations of T wave low level, ST segment down, pathological Q wave, arrhythmia. The study of cardiac structure and function in patients with acute cerebral infarction by echocardiography showed that there was a correlation between acute cerebral infarction and left ventricular ejection fraction, cardiac output and E / AB ratio, suggesting that acute cerebral infarction can cause left ventricular systolic and diastolic Function reduced. Electrocardiogram abnormal changes occur after acute cerebral infarction, and cerebral infarction sites; abnormal cardiac function may affect the prognosis of patients with cerebral infarction. The left ventricular function and cerebral infarction size, location, and carotid atherosclerosis and plaque related research needs further elucidation.
