A real-world data study found that patients with hypertrophic cardiomyopathy (HCM) have more than twice the 5-year risk of infective endocarditis compared to matched controls. This challenges current guidelines, as HCM patients are not currently considered high-risk and are excluded from antibiotic prophylaxis, suggesting a need to re-evaluate prevention strategies for this group.

This is important because it can significantly reduce unnecessary antibiotic use, helping to combat antibiotic resistance and simplify patient care.
