Key result
Lower complexity measures of heart rate variability and altered respiratory rate were significantly associated with poor early and 90-day functional neurological outcomes in ischemic stroke.
Why the study?
Does heart rate variability assessment predict functional neurological outcome in patients with ischemic stroke?
Observational (n=75)
Does heart rate variability assessment predict functional neurological outcome in patients with ischemic stroke?
Heart rate variability parameters and respiratory rate assessed during the first days of ischemic stroke provide prognostic information regarding early and long-term functional neurological outcomes.
No takes yet. Share an insight, caveat, or question.
May support early prognostication in ischemic stroke; leaves open prospective validation before clinical use.
Graff et al. (2013) conducted an observational in ischemic stroke (n=75). Heart rate variability and respiratory rate vs. Patients with good functional neurological outcomes was evaluated on Functional neurological outcome at 7th and 90th days. Lower complexity measures of heart rate variability and altered respiratory rate were significantly associated with poor early and 90-day functional neurological outcomes in ischemic stroke.
