Abstract

The aim of the work is to analyze the data of Echo-CG examination of premature infants who have formed and have not formed bronchopulmonary dysplasia (BPD) to determine the frequency of the formation of pulmonary hypertension (PH). Materials and methods. A total of 199 preterm infants treated in the Department of Pathology of Newborns were examined. The first group included moderate and severe BPD children (n = 117; 59%). The second group consisted of children without BPD within clearly decreed terms (n = 82; 41%). In each group, patients were divided into four subgroups by the gestational age at birth and the timing of the Echo-CG. Results. Only two (1.1%) patients out of 117 BPD children of the first group were diagnosed with pulmonary hypertension (PH). In 3 (2.5%) of 117 infants of the same group, enlargement of the right heart without PH was revealed. Out of 82 children without BPD, two patients had signs of right heart enlargement. PH was not diagnosed in any of the patients in this group. Discussion. To aggravate the efficiency of PH diagnosis, a number of indices of screening echocardiography seem to be increased by additional analysis of changes in the systolic eccentricity index (EI), as a reliable marker of PH in BPD children. Systolic IE should be integrated into screening in preterm infants for the diagnosis of PH. The use of Echo-CG data along with analysis of blood BNP or NT-proBNP blood content be also expanded. Optimizing the diagnosis of PH at the early stages of BPD is necessary to increase the efficacy of targeted therapy and reduce the risk of severe complications of BPD.
