Risk Assessment for Sudden Death in Epilepsy: The SUDEP-7 Inventory.

ABSTRACT: BACKGROUND:Sudden unexpected death in epilepsy (SUDEP) is a major cause of death in those with drug-resistant epilepsy (DRE). There is a need for inventories and biomarkers associated with the risk for SUDEP. OBJECTIVE:To explore the revised SUDEP Risk Inventory (SUDEP-7) in a cohort with DRE and determine the association with Heart Rate and other covariates. METHODS:Twenty-five subjects with severe DRE were enrolled in a clinical trial for epilepsy. Baseline demographics, duration of epilepsy, seizure types, seizure frequency, seizure severity, AEDs, and vital signs were collected. Heart rate variability (HRV) was calculated from 1-h recordings of ECG. A SUDEP Risk Inventory (SUDEP-7) was administered, which included seven validated and weighted risk factors initially identified by Walczak et al. as factors associated with SUDEP risk. RESULTS:The total score on the revised SUDEP-7 ranged from 1 to 7, mean?=?3.4 (SD 1.8). The SUDEP Risk Inventory score was inversely correlated with RMSSD (Pearson r?=?-0.45, p?=?0.027). The following variables were significantly associated with RMSSD: epilepsy duration (p?=?0.02), age (p?=?0.03), and developmental intellectual disability (p?
