Clinical characteristics of severe acute spontaneous subarachnoid hemorrhage complicated by cerebrocardiac syndrome / 中华神经医学杂志

ABSTRACT

Objective To explore the electrocardiogram (ECG) characteristics and prognoses of patients with severe acute spontaneous subarachnoid hemorrhage (SAH) complicated by cerebrocardiac syndrome (CCS).Methods The ECG characteristics and clinical data of 80 patients with severe SAH admitted to our hospital from January 2012 to December 2015 were retrospectively analyzed.The myocardial enzymes,serum troponin T and ECG changes in patients of Hunt-Hess grading Ⅳ and Ⅴ were compared.Results ECG abnormalities at the first time were noted in 76 patients,accounting for 95％.Wave changes (more than two kinds) were noted in 63 patients.ST-T changes were noted in 68 patients,T wave changes in 45,QT interval prolongation in 30,cardiac arrhythmia in 26,conduction block in 11,and abnormal Q wave in 9.The occurrence rates of Q-T interval prolongation,cardiac arrhythmia,conduction block,abnormal Q wave and Glasgow outcome scale (GOS) scores between patients of Hunt-Hess grading Ⅳ and Ⅴ were significantly different (P＜0.05).The myocardial enzyme levels were normal and serum troponin T level slightly increased in patients of Hunt-Hess grading Ⅴ within 2 h of admission.Conclusion ST and T waves changes are the common electrocardiogram manifestations of acute severe SAH patients with CCS;CCS is the important prognostic factors of acute severe SAH patients.
