    Area of Science:

    • Cardiology
    • Infectious Diseases
    • Geriatrics

    Background:

    • Infective endocarditis (IE) is a serious infection affecting heart valves.
    • Understanding IE in elderly populations is crucial due to demographic shifts.

    Purpose of the Study:

    • To describe the clinical features, etiology, complications, and outcomes of infective endocarditis in patients aged 65 and older.
    • To compare IE presentation in elderly versus younger patients.

    Main Methods:

    • Retrospective review of 56 cases of infective endocarditis in patients 65 years or older.
    • Analysis of clinical features, laboratory findings, bacterial etiology, and patient outcomes.

    Main Results:

    • Clinical presentation, laboratory findings, and bacterial causes of IE in older adults were similar to younger patients.

  • Common findings included fever (93%), heart murmurs (86%), and peripheral stigmas (36%).
  • Complications were frequent, including congestive heart failure (64%), neurologic sequelae (36%), and myocardial infarction (13%), with a 45% mortality rate.

    • Conclusions:

    • Infective endocarditis in the elderly shares similarities with younger populations but carries a high mortality risk.
    • Neurologic sequelae, myocardial infarction, and Staphylococcus aureus infection significantly increased mortality.
    • Consider IE in elderly patients presenting with fever, heart murmur, worsening CHF, or acute cerebrovascular events.
