Unexpected Infective Endocarditis: Towards a New Alert for Clinicians

Area of Science:

• Cardiology
• Infectious Diseases
• Internal Medicine

Background:

• Infective Endocarditis (IE) recognition remains challenging despite established guidelines.
• Epidemiological and clinical profiles of IE are shifting, with increased incidence in non-traditional at-risk groups.
• Immunocompromised individuals and even healthy subjects with specific exposures are emerging as at-risk populations.

Purpose of the Study:

• To analyze the subtle and deceptive clinical phenotypes of unexpected Infective Endocarditis.
• To highlight the challenges in diagnosing IE due to evolving patient demographics and presentations.
• To emphasize the need for increased clinical awareness and preventive measures in emergent at-risk populations.

Main Methods:

• Review of clinical cases presenting with subtle and deceptive phenotypes of Infective Endocarditis.
• Analysis of changes in epidemiological and clinical profiles of IE.
• Evaluation of emergent at-risk populations and their unique exposure pathways.

Main Results:

• IE presentation is evolving, moving beyond the conventional paradigm.
• Atypical IE presentations can occur in immunocompromised patients and healthy individuals with specific exposures (e.g., skin contact, implants).
• The unusual clinical context of emergent IE cases may lead to delayed diagnosis and treatment.

Conclusions:

• Clinicians must be aware of unexpected IE clinical courses and consider diagnosis in patients with atypical features.
• Enhanced vigilance is necessary for preventive strategies targeting emergent at-risk populations.
• Recognizing subtle IE phenotypes is critical for improving patient outcomes.
