ABSTRACT

Introduction and Objectives: Hypertension is the most common medical complication of pregnancy, and it can leave permanent sequelae such as neurological, hepatic, hematological or renal disorders. Every three minutes a woman dies due to preeclampsia. During pregnancy, cardiac output suffers an increase of 40%. This increase is secondary to an increase of approxi-mately 30% of systolic volume. The research objective was to predict the onset of preeclampsia-eclampsia syndrome by identifying alterations in cardiac output. Methods: An observational, descriptive, longitudinal, analytical study of prospective cohort was performed, in which by echocardiography, the cardiac output in 31 pregnant women between weeks 11 and 13.6 of ges-tation was determined as the only value, and through prenatal monitoring, the presence or absence of preeclampsia-eclampsia syndrome was observed. Results: The follow-up of 31 pregnant women was achieved, to whom cardiac output was measured, with the following findings: a prevalence of disease of 12.9% with 64.5% of patients correctly diagnosed, with a sensitivity of 75%, positive predictive value of 23%, specificity of 62% and negative predictive value of 94% with a relative risk of 4.1 (95% confidence interval, 0.48 to 35.6). Conclusions: It is possible to establish cardiac output measurement as screening study to predict the onset of preeclampsia syndrome from pre-natal care, thus contributing to the decline in maternal death.
