Key result
Heart rate variability parameters are altered in the acute and chronic stages of ischemic stroke, reflecting autonomic dysfunction and serving as a potential prognostic biomarker.
Why the study?
Autonomic dysfunction after ischemic stroke is frequently linked to cardiac complications and high mortality, making heart rate variability a potential non-invasive autonomic biomarker.
This review highlights the potential of heart rate variability as a non-invasive biomarker for assessing autonomic dysfunction and prognosis in patients with ischemic stroke.
Altered HRV post-stroke signals autonomic dysfunction; leaves open its value for risk stratification or guiding therapy.
Stroke is one of the leading causes of mortality and disability worldwide. Autonomic dysfunction after ischemic stroke is frequently associated with cardiac complications and high mortality. The brain-heart axis is a good model for understanding autonomic interaction between the autonomic central network and the cardiovascular system. Heart rate variability (HRV) analysis is a non-invasive approach for understanding cardiac autonomic regulation. In stroke patients, HRV parameters are altered in the acute and chronic stages of the disease, having a prognostic value. In this literature review we summarize the main concepts about the autonomic nervous system and HRV as autonomic biomarkers in ischemic stroke.
