Background. Recently lung ultrasound (LUS) based on B-lines measurement has been proposed as an effective tool for assessment of pulmonary congestion (PC) in patients with decompensated heart failure (DHF).Objective: to assess the incidence, in-hospital changes and prognostic significance of PC assessed by LUS in DHF patients.Materials and methods. Routine clinical assessment and eight-zone LUS were performed in 162 patients with DHF (men 66%, mean age 68±12 years, hypertension 97%, history of myocardial infarction 44%, atrial fibrillation 60%, ejection fraction [EF] 40±14%, EF<40% 46%, baseline NT-proBNP 4 246 [1741; 6 837] pg/ml). Sum of B-lines ≤5 was considered as normal, 6-15, 16-30 and >30 - as mild, moderate and severe PC, respectively.Results. Using LUS on admission PC was diagnosed in all patients (moderate and severe in 31.5 and 67.3%, respectively). At discharge normal LUS profile was observed in 48.2% of patients. In 33.3, 14.8 and 3.7% of patients PC was mild, moderate, and severe, respectively. According to multivariable Cox regression analysis including age, sex, EF, NYHA functional class, and jugular venous distension sum of B-lines >5 at discharge was associated with higher probability of 12-month all-cause death (hazard ratio [HR] 2.86, 95% confidence interval [CI] 1.15-7.13, p=0.024), sum of B-lines >15 - with higher probability of HF readmission (HR 2.83, 95%CI 1.41-5.67, p=0.003).Conclusion. During hospital stay the incidence of PC as assessed by LUS decreased from 100 to 52% of patients. Sum of B-lines >5 at discharge was independently associated with higher risk of 12-month all-cause death, >15 - with higher risk of 12-month HF readmission.
Aim: to investigate clinical properties of course and outcomes of infective endocarditis (IE) depending on source of infection, to find predictors of mortality in a Moscow general hospital.Materials and methods. We included in this study 176 patients with definite and possible infective endocarditis (the Duke criteria), admitted in our hospital in 2010–2017. Patients were divided in three groups according to source of infection. All patients underwent standard clinical and laboratory assessment, echocardiography, blood culture test combined with blood PCR with sequencing. Inhospital and 1year outcome were evaluated.Results. Among 176 patients with IE 65.3 % were men (median age 57 [35–72] years), most patients (n=149, 84.7 %) had native valve IE. Etiological factor was identified in 127 (72.2 %) cases. Grampositive infective agents prevailed (54 %). Surgery in active phase of the disease was performed in 30 (17 %) patients. Among patients with healthcareassociated IE (n=76, 43.9 %) prevailed those older than 60 years, with high Charlson comorbidity index, with culturenegative IE, and complicated clinical course (mainly progressing heart failure). Patients with intravenous drug use associated IE (n=50, 28.4 %) had low Charlson index, association with hepatitis C viral infection, involvement of tricuspid valve with big vegetations, high frequency of embolic complications, and low inhospital mortality. Group of patients with community acquired IE (n=50, 28.4 %) more often had uncommon causative microorganisms, and had better longterm outcome. Inhospital mortality was 30.1 % (n=53) mostly due to sepsis with multiorgan failure, and heart failure. Risk factors of inhospital death were history of cardiovascular diseases, old age, kidney damage, methicillinresistant Staphylococcus aureus (MRSA) infection, uncontrolled infection, and embolic events. Risk factors of 1year mortality were history of stroke, and heart failure as IE complication. Independent predictors of inhospital death were MRSA infection (odds ratio [OR] 50.32, 95 % confidence interval [CI] 1.66–213.92; p=0.002), persistent infection (OR 18.6, 95 %CI 5.37–64.40; p=0.001), duration of fever >7 days after initiation of antibacterial therapy (OR 13.41, 95 %CI 3.51–51.24; p=0.001); and of death during first year – history of cerebral infarction (OR 4.39, 95 %CI 1.32–14.70; p=0.016)), and heart failure as IE complication (OR 8.1, 95 %CI 1.97–67.09; p=0.016). Among patients subjected to surgery there were no fatal outcomes during 1 year after hospital discharge, while among conservatively treated patients were 21 (14.4 %) deaths (p<0.009).Conclusion. Main clinical features of IE course in patients urgently admitted to a general hospital was dominance of healthcareassociated IE among patients, who were older than 60 years with severe comorbidities. These patients had more complications and worse outcome. Modeling of prognosis identified uncontrolled infection as key factor of unfavorable outcome. Surgery significantly reduced longterm mortality.
