Infective endocarditis (IE) in elderly patients presents unique challenges due to atypical symptoms and confounding factors. Prompt diagnosis and aggressive treatment are crucial for better outcomes in this vulnerable population.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Geriatrics

Background:

  • Infective endocarditis (IE) poses significant morbidity and mortality risks in the elderly.
  • Atypical presentations in older adults necessitate a high index of suspicion for timely diagnosis.

Purpose of the Study:

  • To highlight the diagnostic and therapeutic challenges of infective endocarditis in elderly patients.
  • To identify predisposing risk factors and common pathogens in elderly IE cases.

Main Methods:

  • Review of clinical presentations, risk factors, and causative organisms in elderly patients with IE.
  • Discussion of diagnostic challenges, including echocardiographic limitations due to calcific and prosthetic valves.
  • Emphasis on aggressive diagnostic and therapeutic strategies.

Main Results:

  • Elderly IE is more common in men, with mitral valve involvement more frequent than aortic.
  • Streptococci and staphylococci are the predominant pathogens, found in about 80% of cases.
  • Calcific valvular lesions and prosthetic valves complicate echocardiographic diagnosis.

Conclusions:

  • IE in the elderly requires heightened clinical suspicion due to atypical presentations.
  • Aggressive diagnostic and therapeutic approaches are essential for favorable outcomes in elderly patients with IE.
