Abstract:
Active infective endocarditis (IE) is a disease of low incidence that has showed changes in presentation, diagnosis and treatment options during the past decades. Despite these advances, mortality remains very high. Our goal was to analyze the characteristics of patients with active IE and their relationship with in-hospital mortality over 16 years. Between 1994 and 2010 we performed a prospective registry of 152 consecutive patients (64.5% male, age 45 ± 16 years) admitted with IE. Clinical characteristics, treatment and inpatient outcomes were analyzed. The most common causes of underlying heart disease were: congenital (21%) and rheumatic fever (13.2%). The reasons for hospitalization were fever (76.3%) and heart failure (40.1%). The infectious agent was identified in 69.7% of cases, and the most frequent was Streptococcus viridans. The echocardiogram showed vegetations in 80.9% of patients and 57.8% of them presented complications (the most frequent was heart failure) during hospitalization. Surgical treatment was indicated in 63.2% of cases, mainly due to heart failure. The overall hospital mortality was 30.2%. The presence of complications, requirement of surgical treatment and refractory heart failure were independent predictors of mortality whereas the single presence of vegetation showed better survival rate. The identification of these predictors could help to improve the outcomes in IE.
Insights
Active infective endocarditis (IE) remains a high-mortality disease. Complications, surgery, and refractory heart failure predict mortality, while vegetations indicate better survival.
Area of Science:
- Cardiology
- Infectious Diseases
- Clinical Medicine
Context:
- Active infective endocarditis (IE) presents diagnostic and treatment challenges.
- Despite advances, IE mortality remains high, necessitating further research into risk factors.
- This study analyzes a 16-year prospective registry of IE patients.
Purpose:
- To investigate the clinical characteristics of active IE patients.
- To identify factors associated with in-hospital mortality in IE.
- To analyze trends in IE presentation, diagnosis, and treatment over 16 years.
Summary:
- A prospective registry of 152 IE patients (1994-2010) revealed common causes like congenital and rheumatic heart disease.
- Fever and heart failure were primary admission reasons; Streptococcus viridans was the most frequent pathogen.
- Vegetations were seen in 80.9%, complications in 57.8%, and surgery was indicated in 63.2%.
Impact:
- Overall hospital mortality was 30.2%.
- Complications, surgical necessity, and refractory heart failure independently predicted mortality.
- Identifying these predictors can guide interventions to improve IE patient outcomes.
