Heart rate variability after endovascular coiling is associated with short-term outcomes in patients with subarachnoid hemorrhage

Abstract

Higher HRV in the first day after coil embolization was associated with unfavorable outcomes in patients with SAH. Early detection and appropriate treatment of the overactive sympathetic activity might promote functional recovery after SAH. Abbreviation: BP: Blood pressure; CI: Confidence interval; DBP: Diastolic blood pressure; GCS: Glasgow coma scale; GOS: Glasgow outcome scale; HR: Heart rate; HRV: Heart rate variability; OR: Odds ratio; ROC: Receiver operating characteristics; SD: Standard deviation; SAH: Subarachnoid hemorrhage; SV: Successive variation; SBP: Systolic blood pressure.
