Baroreceptor Sensitivity Predicts Functional Outcome and Complications after Acute Ischemic Stroke.

Area of Science:

• Neurology
• Cardiology
• Autonomic Neuroscience

Background:

• Autonomic dysfunction, including impaired baroreflex sensitivity (BRS), is common after acute ischemic stroke (AIS).
• Impaired BRS may increase the risk of cardiovascular events and mortality following AIS.
• BRS is a potential indicator of long-term prognosis after stroke.

Purpose of the Study:

• To investigate the short-term prognostic significance of BRS in patients with AIS.
• To determine if BRS levels can predict clinical outcomes and complications after AIS.

Main Methods:

• 176 patients admitted within 72 hours of first-ever AIS were enrolled.
• Autonomic function was assessed within 1 week using the Task Force Monitor and transcranial Doppler.
• Patients were categorized into high-BRS and low-BRS groups for comparison.

Main Results:

• The high-BRS group showed significantly lower NIHSS scores at 1 and 2 weeks and discharge.
• Patients with high BRS had better functional outcomes (lower mRS scores) at 1, 3, 6, and 12 months.
• The high-BRS group experienced lower rates of complications and stroke recurrence.

Conclusions:

• BRS is a valuable independent predictor of outcomes following AIS.
• BRS assessment can aid in stratifying stroke patient prognosis.
• Targeting BRS modulation may offer a future therapeutic strategy for acute stroke management.
