[Respiratory infectious complications after acute ischemic stroke]

Area of Science:

• Neurology
• Infectious Diseases
• Critical Care Medicine

Background:

• Respiratory infections are a significant but often overlooked complication in acute ischemic stroke patients.
• Understanding the clinical characteristics of these infections is crucial for improving stroke care and patient outcomes.

Purpose of the Study:

• To investigate the clinical features of respiratory infectious complications in patients experiencing acute ischemic stroke.
• To identify risk factors and outcomes associated with respiratory infections in this patient population.

Main Methods:

• A cohort of 258 acute ischemic stroke patients (May-October 1999) were analyzed.
• Data collected included patient demographics, stroke characteristics, presence of aspiration, feeding tube use, vascular risk factors, and hospital outcomes.
• Patients were compared based on the development of respiratory infections.

Main Results:

• 17.4% of patients developed respiratory infections, with cardioembolic stroke patients showing higher rates (67%).
• Independent risk factors for respiratory infection included aspiration (OR, 5.513) and stroke severity (OR, 1.090).
• Respiratory infections were associated with a 24% mortality rate and independently predicted poor stroke outcomes (OR, 5.838).

Conclusions:

• Aspiration and stroke severity are key predictors of respiratory infectious complications in acute ischemic stroke.
• Respiratory infections are linked to worse stroke outcomes and increased mortality.
• Proactive measures against infectious complications and aspiration are essential for severe acute ischemic stroke patients.
