Outcome in lacunar stroke: A cohort study.

Area of Science:

• Neurology
• Cardiovascular Medicine
• Infectious Diseases

Background:

• Lacunar strokes are a significant cause of neurological disability.
• Identifying prognostic factors is crucial for timely intervention and improved patient outcomes.
• Early clinical deterioration can exacerbate the impact of lacunar stroke.

Purpose of the Study:

• To evaluate the outcomes of lacunar stroke patients at discharge and 6 months post-stroke.
• To identify correlations between cardiovascular risk factors, biochemical parameters, and stroke outcomes.
• To pinpoint prognostic factors for targeted interventions aimed at reducing clinical deterioration.

Main Methods:

• Prospective cohort study of 150 lacunar stroke patients.
• Clinical 6-month follow-up for 98.7% of participants.
• Classification of infarcts by size, shape, and location.

Main Results:

• Predictors of high NIHSS score at discharge included admission NIHSS, leukocytosis, in-hospital infections, and lacunar size.
• Predictors of poor 6-month outcome included admission NIHSS, leukocytosis, elevated CRP, and pre-admission Rankin score.
• Infections, while not causative, significantly influenced functional outcomes.

Conclusions:

• Prompt recognition and treatment of infections are critical for improving functional outcomes in lacunar stroke.
• Controlling inflammatory markers and fever are important in managing lacunar stroke patients.
• Early interventions targeting identified prognostic factors can reduce the incidence and impact of clinical deterioration.
