Objective. Evaluation of the frequency and severity of renal dysfunction in patients with pulmonary embolism (PE) and its impact on the outcome of the disease.
Material and methods. A retrospective analysis of 109 case histories of patients (men – 45%, women – 55%) who were diagnosed with pulmonary embolism during hospitalization was carried out. The median age of patients was 67 (58; 75) years, 14 (12.8%) patients died in the hospital.
Results. The proportion of PE patients with kidney dysfunction (eGFR<60 ml/min/1.73 m2) was 63.3%. Acute kidney injury (AKI) was diagnosed by the value of serum creatinine (sCr) in 59.6% of patients with PE, incl. according to the initial sCr level (n=54) and sCr level in dynamics (n=11). The presence of AKI in patients with PE was associated with the severity of respiratory failure, coagulation profile parameters, and parameters of right ventricular dysfunction. A prognostic model was obtained, which consisted of 3 indicators (PESI index score, blood sodium level less than 135 mmol/l, and the initial sCr), which made it possible to assess the probability of a lethal outcome in patients with PE.
Conclusion. Thus, in the clinical practice of a doctor, when assessing the risk of developing adverse outcomes for patients with PE, it is advisable to take into account the renal function. Patients with AKI should be given special attention because of its negative predictive value for in-hospital mortality in PE.
