Summary

Infective endocarditis presents differently in elderly patients, with distinct predisposing conditions and pathogens. Delayed diagnosis in older adults contributes to a poorer prognosis despite similar complication rates.

Context:

Infective endocarditis (IE) is a serious infection affecting heart valves.
Clinical presentation and outcomes of IE can vary significantly with age.
Understanding age-specific features is crucial for effective management.

Purpose:

To compare the clinical features, causative microorganisms, and outcomes of infective endocarditis in elderly patients (>= 60 years) versus younger adults (< 60 years).

Summary:

Elderly IE patients more frequently had calcific aortic valves or artificial devices and higher rates of extracardiac disorders (e.g., neurological disease).
Staphylococcus epidermidis was more common in the elderly, while Streptococcus species predominated in younger patients.
Diagnosis was significantly delayed in the elderly, leading to a poorer prognosis despite similar rates of heart failure and embolic complications.

Impact:

The study highlights that while IE complications are similar across age groups, delayed diagnosis in the elderly, often with comorbidities, results in worse outcomes.
Findings underscore the need for heightened clinical suspicion and prompt diagnostic evaluation of IE in older individuals.
This research informs clinical practice and emphasizes age-specific considerations in IE management.
