Recognition, management and prophylaxis of endocarditis

Area of Science:

• Cardiology
• Infectious Diseases
• Internal Medicine

Background:

• Infective endocarditis (IE) presents with high morbidity and mortality, particularly in the elderly, IV drug users, and prosthetic valve patients.
• Diverse clinical manifestations necessitate high clinical suspicion for early diagnosis.
• Evolving diagnostic tools and criteria are crucial for timely IE identification.

Purpose of the Study:

• To review recent advancements in the diagnosis and management of infective endocarditis.
• To highlight changing trends in IE treatment and prophylaxis strategies.
• To discuss the impact of new pathogens and diagnostic criteria on IE care.

Main Methods:

• Review of current literature on infective endocarditis diagnosis and treatment.
• Analysis of trends in echocardiography utilization and diagnostic criteria (Duke's criteria).
• Examination of shifts in antimicrobial resistance patterns and therapeutic regimens.

Main Results:

• Transesophageal echocardiography improves early and precise identification of valvular changes.
• New Duke's criteria enhance IE diagnosis and categorization.
• Increased prevalence of challenging pathogens like MRSA and resistant enterococci noted.
• Therapeutic shifts include shorter courses, oral/once-daily regimens, and outpatient programs.
• Antibiotic prophylaxis remains controversial with low patient compliance.

Conclusions:

• Advances in echocardiography and diagnostic criteria are improving IE detection.
• Current management trends aim for cost reduction and improved patient quality of life.
• Challenges persist in IE prevention and managing resistant microbial strains.
