Relationship between the changes of electrocardiogram and the prognosis of the elderly patients with acute cerebral ischemic infarction / 中国医师杂志

ABSTRACT

Objective To investigate the changes of electrocardiogram in elderly patients with acute cerebral ischemic infarction (CIS),and to analyze the relationship between the electrocardiogram and the prognosis of the patients.Methods 132 elderly patients with acute CIS in the hospital from January 2013 to December 2016 were enrolled.12 lead electrocardiogram was performed within 48 hours after onset and 7 days after onset,and the relationship between electrocardiogram abnormality and infarct type,severity,and prognosis were analyzed.The independent predictors of poor prognosis based on improved Rankin's score at discharge were evaluated.Results 83 cases (62.88％) had abnormal electrocardiogram.The main type of abnormal electrocardiogram was S-T segment abnormalities,followed by arrhythmia.The severity of illness in patients with abnormal electrocardiogram were significantly more serious than in those who did not detect abnormal electrocardiogram (P ＜ 0.05).The severity of illness in patients detected abnormal electrocardiogram over 2 times were significantly more serious than in those who detected abnormal electrocardiogram only within 48 hours after onset or 7 days after onset (P ＜ 0.05).Shorter time from onset to admission,complete anterior circulation infarction according to Oxfordshire Community Stroke Project (OCSP)classification,abnormal electrocardiogram (＞ 2 times) were independent risk factors for poor prognosis at discharge (P ＜ 0.05).Conclusions Electrocardiogram abnormity is common in elderly patients with CIS,and abnormal electrocardiogram detected over 2 times may indicate poor prognosis,which will benefit for the treatment schemes of patients.
