Why the study?
Information was lacking regarding the role of resting heart rate in predicting outcome events in patients with ischemic stroke and atrial fibrillation.
Is resting heart rate level or variability associated with stroke recurrence and mortality in patients with acute ischemic stroke and atrial fibrillation?
Is resting heart rate level or variability associated with stroke recurrence and mortality in patients with acute ischemic stroke and atrial fibrillation?
In patients with acute ischemic stroke and atrial fibrillation, mean heart rate during the acute phase has a J-shaped association with 1-year mortality, but not with stroke recurrence.
No takes yet. Share an insight, caveat, or question.
Heart rate monitoring may aid mortality risk stratification in acute stroke with AF; hypothesis-generating without supporting rate targets for recurrence prevention.
