Stroke complications, including ischemic and hemorrhagic types, are frequent in infective endocarditis patients, often occurring during uncontrolled infection. Early diagnosis and management are crucial for improving outcomes in these high-risk individuals.

Area of Science:

  • Cardiology
  • Neurology
  • Infectious Diseases

Background:

  • Infective endocarditis (IE) is a serious infection affecting heart valves.
  • Stroke is a significant complication of IE, impacting patient prognosis.
  • Understanding stroke patterns in IE is vital for clinical management.

Purpose of the Study:

  • To investigate the incidence and characteristics of stroke in patients with infective endocarditis.
  • To identify risk factors and timing of stroke events in IE.
  • To analyze the relationship between stroke and infection control in IE.

Main Methods:

  • Retrospective review of 212 consecutive IE episodes in 203 patients (1978-1986).
  • Analysis of stroke types (ischemic, hemorrhagic) and non-central nervous system emboli.

  • Correlation of stroke with valve type, vegetation presence, and infection control.

    • Main Results:

    • 21% of IE episodes were complicated by stroke.
    • Ischemic stroke was more common (19%) than hemorrhagic stroke (7%) in native valve endocarditis.
    • Most ischemic strokes occurred at presentation or within 48 hours of diagnosis; hemorrhage was linked to S. aureus and arteritis.

    Conclusions:

    • Stroke remains a frequent and critical complication of infective endocarditis.
    • Stroke events in IE are often clustered during periods of uncontrolled infection.
    • Timely diagnosis and effective management of IE are essential to mitigate stroke risk.
