Assessment of interstitial edema in patients with intermediate function of the left ventricle after resolving of acute decompensation of heart failure

Background. According to the recommendations of the European Society of Cardiology, ultrasound examination of the lung can be used to assess congestive changes, however, this method has so far a low recommendation class IIb and a level of evidence C, which can be regarded as a consequence of its insufficient knowledge.

The aim of the research. To study ultrasound characteristics of the lung tissue in patients with intermediate left ventricular function after resolving of acute decompensation of heart failure.

Materials and methods. The ultrasound profile of the lung tissue was studied in 71 patients after resolution of acute heart failure decompensation under intermediate left ventricular function. The average age of patients studied was 65.2 ± 3.6 years. 64.3% of them were males ,25.7%-females. Using the ultrasonic method, B-lines were studied, the distance between them being 3 mm and 7 mm in a semi-quantitative manner, according to the method of E. Picano in 2016. The results were statistically processed

Results. In persons after the acute decompensation of the heart failure residual congestion persisted with interstitial component dominated in both lungs. Appearance of interstitial lung edema to be considered as prognostic factor of re-hospitalizations rate increasing.

Conclusion. Interstitial congestion in the pulmonary parenchyma considered as a factor in the deterioration of the clinical course of heart failure sign of its acute decompensation. In this connection, it is interesting to identify interstitial pulmonary edema at the early stage to prevent real clinical presentation of acute decompensation of the heart failure.
