Infective endocarditis: prevention, diagnosis and management

Area of Science:

• Cardiology
• Infectious Diseases
• Internal Medicine

Background:

• Infective endocarditis (IE) persists as a significant clinical challenge, with prevention strategies remaining inadequate.
• While causative bacteria are largely unchanged, there is a notable rise in nosocomial infections and IE associated with intravenous drug abuse.
• The clinical dichotomy of acute versus subacute presentations remains relevant for patient management.

Purpose of the Study:

• To review the current understanding of infective endocarditis, focusing on epidemiology, clinical presentation, diagnosis, and management.
• To highlight the importance of early and accurate diagnosis for improving patient outcomes.
• To emphasize the critical role of echocardiography and microbiological investigations in guiding treatment decisions.

Main Methods:

• Integration of clinical data, including patient history and physical examination.
• Performance and interpretation of blood cultures for microbiological identification of causative agents.
• Utilization of echocardiography (transthoracic and transesophageal) to visualize vegetations and assess cardiac complications.

Main Results:

• Cardiac and neurological complications are common in infective endocarditis, significantly increasing mortality risk.
• Diagnosis relies on combining clinical findings with microbiological and imaging data.
• Echocardiography is vital for detecting vegetations, evaluating hemodynamic impact, and identifying specific cardiac sequelae.

Conclusions:

• Accurate risk stratification is achievable through the comprehensive integration of multiple clinical parameters.
• Prompt identification of the etiological agent is paramount before commencing antimicrobial therapy.
• Surgical intervention is often necessary and requires timely execution when indicated to manage complications and improve survival.
