Relationship between pre-stroke cardiovascular medication use and stroke severity.

Area of Science:

• Neurology
• Cardiology
• Pharmacology

Background:

• Stroke represents a significant global health challenge, contributing to substantial morbidity and mortality.
• While risk factors and cardiovascular medications are known to influence stroke incidence, their impact on stroke severity remains less understood.

Purpose of the Study:

• To investigate the association between pre-stroke use of cardiovascular medications and the severity of stroke.
• To identify specific medication classes that may influence stroke outcomes.

Main Methods:

• A retrospective analysis of anonymized data from 1974 suspected stroke patients admitted to Universitair Ziekenhuis Brussel.
• Stroke severity was assessed using the National Institute of Health Stroke Scale (NIHSS).
• Multivariable linear regression and cumulative odds ordinal logistic regression models were employed to analyze medication effects.

Main Results:

• Pre-stroke use of Angiotensin II receptor blockers (ARBs), statins, and antiarrhythmics showed initial associations with stroke severity.
• Ordinal logistic regression revealed a significant relationship between pre-stroke statin use and lower NIHSS scores (OR 0.740, 95% CI 0.580-0.944).

Conclusions:

• Pre-stroke statin use is significantly associated with reduced stroke severity.
• No significant associations were found between other studied cardiovascular medication groups and stroke severity as measured by the NIHSS.
