[Infective endocarditis: analysis of 300 episodes]

Area of Science:

• Cardiology
• Infectious Diseases
• Microbiology

Context:

• Infective endocarditis (IE) is a severe infection affecting the heart's inner lining, often the valves.
• Understanding the diverse etiologic agents and patient cardiac status is crucial for effective management.
• Despite advances in treatment, IE continues to pose significant mortality risks.

Purpose:

• To investigate the clinical features, causative agents, treatment modalities, and mortality rates of infective endocarditis.
• To analyze the relationship between specific etiologic agents, underlying cardiac conditions, and patient outcomes.
• To evaluate the impact of medical and surgical interventions on mortality in IE patients.

Summary:

• A study of 300 IE episodes revealed viridans group streptococci (31%) and Staphylococcus aureus (20%) as common etiologic agents.
• Valvular heart disease (40%) and prosthetic heart valves (23%) were the most frequent underlying cardiac conditions.
• Mortality was 26% overall, varying significantly with etiologic agents and cardiac status, notably higher in prosthetic valve endocarditis (43%).

Impact:

• This research highlights the persistent high mortality of infective endocarditis, emphasizing the need for tailored treatment approaches.
• Findings underscore the importance of considering specific microbial causes and patient cardiac health when managing IE.
• The study provides critical data for refining treatment protocols and improving survival rates for IE patients, particularly those with prosthetic valves or complex cardiac histories.
