Autonomic dysregulation in acute ischemic stroke patient with insomnia

Abstract

ObjectiveThis study aimed to assess autonomic dysregulation by measuring Heart Rate Variability (HRV) parameters in acute ischemic stroke patients with insomnia. MethodsThis was a descriptive observational study on 5 participants (4 females and one male) with acute ischemic stroke and insomnia. All participants were assessed through the Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI) and then tested using a Polar H10 device for 5min recording during night sleep. The collected data analyzed by Kubios HRV Analysis Software 3.2 (MATLAB, Kuopio, Finland). ResultsThis study showed that all participants (age 51.2±12.61) had subthreshold to moderate insomnia based on ISI (14.8±2.48) and had poor sleep quality based on PSQI (16.4±3.72). There was an increase of mean heart rate (HR) (81.8±13.86), root mean square of successive differences (rMSSD) (46.6±38.05), and sympathetic nervous system index (SNS Index) (1.542±1.567), as well as the decrease of standard deviation of normal-normal interval (SDNN) (37.8±20.53), low frequency (LF) (449.2±371.8), high frequency (HF) (812.6±773.8), LF/HF (1.89±1.72), and parasympathetic nervous system index (PNS Index) (−0.462±1.210). ConclusionsThe Analysis of HRV showed an autonomic dysregulation in the form of parasympathetic dysfunction and sympathetic hyperactivation during night sleep in the acute phase of ischemic stroke with insomnia.
