Infective endocarditis affects 0.85 per 1000 hospital admissions, with drug addiction and prosthetic valves as key risk factors. Staphylococcus aureus infections are increasing, but overall mortality has decreased.

Area of Science:

Cardiology
Infectious Diseases
Epidemiology

Background:

Infective endocarditis presents a significant public health challenge.
Understanding its current epidemiological trends is crucial for effective management.

Purpose of the Study:

To determine the current epidemiological situation of infective endocarditis.
To analyze the evolution of infective endocarditis in recent years.

Main Methods:

Retrospective analysis of hospital admissions.
Echocardiography for diagnosis.
Identification of causative microorganisms.

Main Results:

Incidence of 0.85 per 1000 hospital admissions; mean age 43.

Key risk factors: drug addiction (32%) and prosthetic valves (23%).

Commonly affected valves: tricuspid (28%), mitral (27%), prosthetic (23%). Causative agents: S. aureus (19), Streptococcus (15), S. epidermidis (11). Echocardiography diagnostic in 90%; 22% underwent valve replacement. Overall mortality 10%.

Conclusions:

Infective endocarditis profile includes high rates in parenteral drug users and prosthetic valve carriers.
Increasing S. aureus infections and decreasing Streptococcus infections observed.
Overall mortality shows a declining trend.
