Rutgers Health researchers found that high blood pressure problems during pregnancy were significantly associated with fatal heart disease up to a year after birth. All hypertensive disorders that cause dangerously high blood pressure during pregnancy – chronic hypertension, gestational hypertension, preeclampsia without severe features, preeclampsia with severe features, superimposed preeclampsia and eclampsia – except gestational diabetes, fatal were associated with a doubling in risk. Heart disease compared to women with normal blood pressure.
According to a study published in Pediatric and Perinatal Epidemiology, eclampsia, a syndrome in which high blood pressure causes seizures, was associated with about a 58-fold increase in fatal heart disease.
“Maternal and perinatal mortality rates in the US are higher than in other high-income countries and are rising, but more than half of deaths related to heart disease are prevented,” said lead author Rachel Lee, data analyst at Rutgers Robert Wood Johnson Medical. May go.” School. “This study provides new information about how each high blood pressure disorder is related to fatal heart disease, so healthcare providers can more closely monitor patients with such complications and develop strategies to keep them healthy postpartum.” Can.”
Researchers used a nationwide readmissions database to examine pregnancy-related mortality for women ages 15 to 54 from 2010 to 2018. Data from more than 33 million delivery hospitalizations identified hypertensive disorders in 11 percent of patients, but that number increased over time. In 2010, 9.4 percent of patients included in the study had hypertensive disorders of pregnancy. By 2018, this figure had more than halved to 14.4 percent.
“We have become better at predicting, diagnosing and treating preeclampsia in this country, so the risk of death for any patient with that condition is decreasing,” said Cande Anant, chief of the epidemiology and biostatistics division at the department. ” Professor of Obstetrics, Gynecology and Reproductive Sciences at Rutgers Robert Wood Johnson Medical School and senior author of the study.
Unfortunately, Anant said, the sharp increase in the number of patients developing chronic hypertension has been offset by the improved ability to treat it.
“The incidence of chronic hypertension in people of childbearing age is rapidly increasing, but optimal treatment strategies remain uncertain,” he said. “While we are treating more pregnant people with mild hypertension with antihypertensive medications, many questions remain about the correct definition of hypertension in pregnant people compared to non-pregnant individuals.”
Pregnant people with hypertensive disorders, especially those with pre-existing high blood pressure, need high-quality care because heart disease and related cardiovascular symptoms can be confused with normal symptoms of normal pregnancy. Delaying diagnosis increases the incidence of preventable complications, the study authors said. Early identification and optimal treatment of hypertensive disorders, especially preeclampsia–eclampsia, are important for primary prevention of maternal stroke.
