RESUMEN
Infective endocarditis (IE) is a life threatening disease requiring lengthy hospitalizations, complex multidisciplinary management and high health care costs. In this study, we analyzed the National Readmissions' Database (NRD) to identify infective endocarditis cases and the causative organisms, clinical determinants, length of stay, in-hospital mortality, and 30-day hospital readmission rates. The study cohort was derived from Healthcare Cost and Utilization Project's National Readmission Database between 2010-15. We queried the National Readmissions' Database using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnostic code for infective endocarditis (421.0) and identified a total of 187,438 index admissions. SAS 9.4 (SAS Institute Inc., Cary, NC) was utilized for statistical analyses. A total of 187,438 patients with a primary diagnosis of IE were identified over 6 years (2010-2015). Twenty-four percent (44,151 patients) were readmitted within 30 days. Most common etiologies for readmission included sepsis (14%), acute heart failure (8%), acute kidney injury (6%), intracardiac device infection (5.6%) and recurrence of IE (2.7%). Predictors of increased readmissions included female sex, staphylococcus aureus infection, diabetes, chronic lung disease, chronic liver disease, acute kidney injury, acute heart failure and anemia. In-hospital mortality for the readmission of IE was 13%, and average length of stay during the re-admission was 12 days. IE is associated with high rates of index admission mortality and for 30-day readmissions of which are associated with a substantial risk of death.

OBJECTIVES: Pulmonary hypertension (PH) is extremely common in acute decompensated heart failure (ADHF) patients and predicts increased mortality. Obstructive sleep apnea (OSA), highly prevalent in congestive heart failure patients, may contribute to further elevated pulmonary pressures. This study evaluates the impact of positive airway pressure (PAP) therapy on PH in patients admitted for ADHF with OSA. METHODS: A two-center randomized control trial comparing standard of care (SOC) therapy for ADHF versus addition of PAP therapy in patients with concomitant OSA. RESULTS: Twenty-one consecutive patients were enrolled with 1:1 randomization to SOC versus SOC plus 48-hour PAP therapy protocol. In the intervention arm, the mean pulmonary artery systolic pressure (PASP) difference before therapy and after 48 hours of PAP therapy was -15.8 ± 3.2 (58.6 ± 2.5 mm Hg to 42.8 ± 2.7) versus the SOC arm where the mean PASP difference was -5.2 ± 2.6 (62.7 ± 3.3 mm Hg reduced to 57.5 ± 3.9) (p = 0.025). In addition, ejection fraction in the intervention arm improved (3.4 ± 1.5% versus -0.5 ± 0.5 %) (p = 0.01). Significant improvement was also noted in tricuspid annular plane systolic excursion (TAPSE) and right ventricular systolic area in the intervention arm but not in NT-pro-BNP or 6-minute walk distance. CONCLUSIONS: In patients with ADHF and OSA, addition of 48 hours of PAP therapy to SOC treatment significantly reduced PH. In addition, PAP therapy was able to improve right and left ventricular function. ClinicalTrials.gov identifier: NCT02963597.
