Infective endocarditis has evolved since 1885, with older patients, diverse causes, and acute presentations. Advances improve survival, but emerging resistant organisms pose new challenges.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Medical History

Background:

  • Infective endocarditis (IE) presentation has shifted significantly since the 19th century.
  • Historically, IE was uniformly fatal, but modern therapies have improved survival rates.
  • Current IE cases often involve older patients, altered cardiac lesions, and unusual pathogens like gram-negative bacteria and fungi.

Purpose of the Study:

  • To highlight the evolving landscape of infective endocarditis.
  • To compare contemporary IE with historical descriptions.
  • To discuss recent advancements in IE diagnosis and management.

Main Methods:

  • Comparative analysis of historical and current endocarditis data.
  • Review of recent literature on diagnostic and therapeutic advances.

  • Identification of key changes in patient demographics, causative organisms, and clinical presentation.

    • Main Results:

    • Median patient age has increased, and predisposing cardiac lesions have changed.
    • Increased incidence of IE caused by gram-negative bacteria and fungi.
    • More acute presentations and fewer classic late-stage findings are observed.
    • Emergence of multiresistant organisms presents a challenge, echoing historical difficulties.

    Conclusions:

    • Infective endocarditis management has advanced, improving survival.
    • New diagnostic tools like transesophageal echocardiography and specific receptor identification enhance diagnosis.
    • Outpatient oral antibiotic therapy is now viable for certain streptococcal infections.
    • Despite progress, challenges like antimicrobial resistance necessitate ongoing research and vigilance.
