Introduction:

Infective endocarditis is a disease with a varied clinical presentation. It is becoming more frequent due to health-related care.

Objective:

To determine the complications of patients with bacterial infective endocarditis at the time of diagnosis and their relationship with the causal agent and offer a general description of the demographic and clinical characteristics present in patients of the Hospital Nacional of Itauguá, Paraguay, in the period 2017- 2021.

Material and methods:

Descriptive, observational, retrospective study that included 37 patients diagnosed with infective endocarditis with isolated germ.

Results:

The mean age was 45±14 years, the majority came from the urban area and was male (65%). The most frequent comorbidity was chronic kidney disease (50%). Invasive procedures (simple central venous catheter) were the most frequent source of bacteremia (65.22%). The most compromised valve was the aortic, the most frequent complication was heart failure (70.27%) and there was 49% of fatal outcomes. The most frequent germ and cause of the highest morbidity and mortality was Staphylococcus aureus (43.24%).

Conclusion:

Chronic kidney disease was the main risk factor. Being a carrier of a simple venous hemodialysis catheter was related to the isolation of Staphylococcus aureus as the most frequent causal agent. This germ was related to the high rate of complications at the time of admission and the high percentage of fatal outcomes.
