Introduction. Preeclampsia is a significant issue in contemporary obstetrics. The purpose of this study is investigated the impact of preeclampsia on maternal-fetal morbidity and mortality, as well as the long-term maternal risk of the condition. Material and Methods. The study was conducted at the Department of Obstetrics and Gynecology SCM-1 in mun. Chisinau, and included 98 pregnant women whose pregnancy was complicated by preeclampsia. The women were evaluated using a questionnaire, and their serum cardiac troponin I levels were measured to determine diagnostic value. Results. The study showed that preeclampsia is a significant issue that can lead to maternal and fetal morbidity and mortality. In the study was a high incidence of HELLP syndrome (21.4%), embedded normal placental detachment (11.2%), and DIC with bleeding syndrome (7.1%). The study found that levels of troponin I, which is the best-known indicator of minor myocardial injury, were higher in pregnant women with severe preeclampsia.The study also showed that there is a strong correlation between a history of preeclampsia and the risk of developing ischemic heart disease later in life. Conclusion. This study demonstrated that preeclampsia is associated with an increased risk for maternal and fetal morbidity. The identification of sensitive biochemical markers of cardiac ischemia in pregnancy and postpartum depending on the severity of preeclampsia may serve as an additional marker in the diagnosis of preeclampsia severity and the prophylaxis of myocardial infarction during childbirth and the postpartum period.
