Summary
Blood pressure significantly drops within the first week after acute hemispheric stroke, stabilizing thereafter. Alcohol consumption impacts systolic blood pressure decline post-stroke.
Area of Science:
- Neurology
- Cardiovascular Medicine
- Clinical Research
Background:
- Acute hemispheric stroke necessitates understanding post-hospitalization physiological changes.
- Blood pressure (BP) fluctuations are critical in stroke patient management.
Purpose of the Study:
- To determine the pattern of blood pressure change following hospitalization for acute hemispheric stroke.
- To investigate factors influencing BP changes, including stroke characteristics and patient history.
Main Methods:
- Prospective study of 292 acute hemispheric stroke patients.
- BP measurements taken at admission, 24 hours, 1 week, and 4-6 weeks.
- Analysis correlated BP changes with stroke risk factors, type, severity, and antihypertensive treatment.
Main Results:
- Significant BP decline observed within the first week post-stroke (systolic: 22 mm Hg, diastolic: 12 mm Hg), with minimal further changes.
- Higher initial systolic BP in cerebral hemorrhage vs. cerebral infarction patients.
- Moderate to heavy alcohol consumption linked to lower convalescent systolic BP.
Conclusions:
- A marked, early fall in BP occurs in the first week after acute hemispheric stroke.
- Cerebral hemorrhage is associated with higher initial systolic BP compared to cerebral infarction.
- Alcohol consumption patterns influence post-stroke systolic BP trends.
