Long-Term Cardiovascular Risk and Maternal History of Pre-Eclampsia

Pre-eclampsia is a severe pregnancy complication affecting 5-8% of pregnancies worldwide, marked by high blood pressure and organ damage typically occurring after 20 weeks of gestation. It is a leading cause of maternal and fetal morbidity and mortality. Though its exact cause is unknown, it involves placental abnormalities and improper blood vessel development. Risk factors include a history of pre-eclampsia, chronic hypertension, diabetes, obesity, and autoimmune disorders. Symptoms include high blood pressure, proteinuria, headaches, vision changes, and abdominal pain. Untreated, it can lead to seizures, stroke, preterm birth, or death. Delivery is the definitive treatment, with management strategies such as monitoring and blood pressure control. Pre-eclampsia significantly increases long-term cardiovascular disease (CVD) risks, including hypertension, ischemic heart disease, and stroke, linked to shared mechanisms like endothelial dysfunction and inflammation. Women with severe or recurrent pre-eclampsia have heightened risks, often developing chronic hypertension within a decade postpartum. It also impacts offspring, with daughters at elevated risk for pre-eclampsia and CVD. Hypertensive disorders of pregnancy, including pre-eclampsia, induce changes like left ventricular hypertrophy and diastolic dysfunction, raising risks for heart failure with preserved ejection fraction and coronary atherosclerosis. Overlapping with peripartum cardiomyopathy, pre-eclampsia underscores a spectrum of pregnancy-related cardiovascular disorders. Long-term monitoring and lifestyle interventions are crucial for managing risks, with research into genetic and biological mechanisms offering the potential for targeted prevention.
