Clinical Practice Update on Infectious Endocarditis

Area of Science:

• Cardiology
• Infectious Diseases
• Public Health

Background:

• Infectious endocarditis is a severe condition affecting thousands annually in the US.
• Current diagnostic criteria (modified Duke Criteria) have limitations in sensitivity.
• Diagnostic imaging and risk stratification tools are improving endocarditis diagnosis and management.

Purpose of the Study:

• To review current diagnostic and management strategies for infectious endocarditis.
• To highlight challenges in managing patients who inject drugs with endocarditis.
• To discuss emerging therapeutic and care delivery models.

Main Methods:

• Review of recent literature on diagnostic imaging, risk stratification, and treatment of infectious endocarditis.
• Analysis of challenges associated with patient populations, including intravenous drug users.
• Evaluation of evidence for alternative antibiotic therapies and multidisciplinary care models.

Main Results:

• Advances in imaging and risk calculators enhance diagnostic accuracy for infectious endocarditis.
• Patients who inject drugs present unique management issues, including recurrent infections and the need for addiction treatment.
• Oral/depo antibiotics and shorter antibiotic courses show promise as alternatives to traditional intravenous therapy.

Conclusions:

• Infectious endocarditis requires a multidisciplinary team approach for optimal patient outcomes.
• Improved access to medication-assisted treatment is crucial for patients with opioid use disorder and endocarditis.
• Novel antibiotic regimens may offer effective and more convenient treatment options.
