Characteristics of bacterial endocarditis in heroin addicts in Detroit.
Over 24 months (January 1972-December 1973) 48 intravenous heroin users were admitted to Detroit General Hospital with 50 episodes of bacterial endocarditis (B.E.). Staphylococcus aureus (25 cases), enterococci (13 cases), and Pseudomonas aeruginosa (5 cases) were the usual pathogens, accounting for 86 per cent of these illnesses. Occasional episodes were due to other streptococci or diphtheroids which were susceptible to penicillin G. Staphylococcal and pseudomonas endocarditis usually involved the tricuspid valve, while enterococci affected aortic or mitral valves. Pre-existing valvular heart disease was not the sole determinant of the site of infection.
