RESUMO
OBJECTIVES: This study aimed to assess the effect of the inflammatory process on fetal cardiac functions in pregnant women with autoimmune diseases (AID). METHODS: This prospective study included 36 pregnant women with diagnosed AID. Nineteen systemic lupus erythematosus, 12 antiphospholipid syndrome, 5 Sjögren's syndrome, and 72 healthy pregnancies were included. Fetal cardiac functions were evaluated with pulsed-wave, tissue Doppler, and M-mode echocardiography. RESULTS: Sociodemographic data were similar in both groups. Significant increases were found in tricuspid E (43.5 ± 0.9, p<0.001) and A (59.2 ± 2.2, p<0.001) and E/A (0.74 ± 0.03, p<0.001), E'/A' (0.64 ± 0.15, p<0.001), E/E' (6.5 ± 0.6, p<0.001), and left ventricular myocardial performance index (0.54 ± 0.03, p=0.005). We demonstrated a significant decrease in tricuspid E' (6.7 ± 0.6, p<0.001) and S' (6.9 ± 1, p<0.001) and in TAPSE (7.7 ± 0.5, p=0.002). We also found a significantly prolonged PR interval (130 ± 8, p<0.001). There was a significant increase in E' (6.8, p=0.033) and a significant decrease in E/E' ratio (6.4, p=0.027) in the group using hydroxychloroquine (HCQ) compared to non-users. CONCLUSIONS: We found that pregnancy with autoimmune diseases affects fetal heart functions. Additionally, hydroxychloroquine may positively affect the heart of AID fetuses. This information might be useful to clinicians in the follow-up of cardiovascular diseases.

AIM: This study aims to investigate the effects of maternal asthma on fetal cardiac functions. METHODS: The study was planned with 30 pregnant women who presented to a tertiary health center and were diagnosed with asthma and 60 healthy controls with similar gestational ages. The fetal echocardiographic assessment was assessed between 33 and 35 weeks of gestation with pulsed-wave Doppler (PW), M-mode, and tissue Doppler imaging (TDI). Fetal cardiac functions were compared between maternal asthma and the control group. Cardiac functions were assessed according to the duration of maternal asthma diagnosis, as well. RESULTS: Early diastolic function parameters, tricuspid E wave (p = .001), and tricuspid E/A ratio (p = .005) were significantly lower in the group with maternal asthma. Tricuspid annular plane systolic excursion (TAPSE) and measurements of mitral annular plane systolic excursion (MAPSE) values were statistically lower in the study group than in the control group; p = .010 and p = .012, respectively. Parameters assessed with TDI (E', A', S', E/E', and MPI' of tricuspid valves) and global cardiac function parameters assessed with PW like myocardial performance index (MPI) and left cardiac output (LCO) were similar between groups (p > .05). Although, MPI did not change between groups, and the isovolumetric relaxation time (IVRT) value was prolonged in maternal asthma cases (p = .025). CONCLUSION: We found that maternal asthma disease causes alteration in fetal diastolic and early systolic cardiac functions, but the global fetal cardiac function does not change. Diastolic heart function values also varied with the duration of maternal asthma. Prospective studies are needed to compare fetal cardiac functions with additional patient groups according to disease severity and type of medical treatment.
