Filter by:This case-control study aims to investigate the association between B vitamins and gestational hypertension or preeclampsia.
There may be a role for Lisinopril in improving renal protection in post-partum women who had preeclampsia during pregnancy. The aim of this study is to determine whether routine initiation of Lisinopril after delivery, in women who had preeclampsia while they were pregnant, can control high blood pressure and improve kidney function.
According to U.S. Pharmacist® "low-dose aspirin refers to dosages between 81 mg and 325 mg taken every day to prevent heart attacks, strokes, and colon cancer." It has been found through research that low-dose aspirin also decreases the risk of preeclampsia. The American College of Obstetrics and Gynecologists (ACOG) recommends low-dose aspirin (81mg/day) for women at high risk of preeclampsia. However, some researchers report that a dose of aspirin < 100 mg/day does not seem to decrease the risk of preeclampsia. Another trial studying patients who are at a high risk for preterm preeclampsia, reported a reduction in the occurrence of preeclampsia among patients taking aspirin at a dose of 150 mg. The purpose of this pragmatic randomized study is to compare the difference in the effectiveness of two doses of aspirin: 81 mg versus 162 mg in the prevention of preeclampsia in pregnant women who are at a moderate to high risk for developing preeclampsia.
To determine if the use of impedance cardiography can identify appropriate medications for use in treating chronic hypertensive patients to decrease the risk of preeclampsia.
The purpose of this study is to compare 3 methods of assessing endothelial function in healthy female volunteers and pregnant women with and without pregnancy induced hypertension. The methods under comparison are simultaneous tissue oxygen saturation (StO2), EndoPAT and Sphygmocor (pregnant women only). 35 participants (15 healthy, 10 pregnant normal blood pressure, 10 pregnant with hypertension) will be enrolled.
Randomized controlled trial to assess efficacy of Sildenafil in addition to expectant management for the treatment of preterm preeclampsia
Preeclampsia is a disease of pregnancy affecting 3% to 8% of all pregnancies and is a major cause of maternal and perinatal morbidity and mortality. Characterized by alter placentation with subsequent release of inflammatory mediators leading to a generalized endothelial dysfunction. It is now accepted that endothelial dysfunction heralds the clinical manifestations of preeclampsia. The side-stream darkfield (SDF) microscopy device emits a 550 nm green light with a depth region of interest of 500 um. Green light is absorbed by the erythrocytes and appears black. SDF is a well-known non-invasive tool that can study the microcirculatory changes. It was used before in many situations especially in sepsis and septic shock patients. Near-infra-red spectroscopy (NIRS) device, measures the absorbance of near-infra-red (NIR) light by tissues perfused with oxygenated blood, and is capable of measuring changes in parenchymal volume tissues. It was used before in many situations (including pregnant patients) to reflect the tissue oxygenations. The investigators are planning to use the SDF and NIRS tools to study the microcirculatory change in preeclamptic subjects and normal pregnant subjects. If these two devices are able to determine any changes this should stand as a baseline for future studies in this field.
The study will be an open controlled pilot study of 6 patients with early-onset severe preeclampsia. Patients will receive Atenativ in addition to conventional therapy The patients will be followed up within the study until three days after delivery. Laboratory analyses and uterine and umbiliacal blood flow will be determined.
The purpose of this study is to verify if postprandial walks are effective in obese pregnant women, as regards to gestational weight gain and typical diseases of that period, as gestational diabetes and preeclampsia. Perinatal outcomes will be observed, such as macrosomia, shoulder dystocia and fetal death.
The Investigator would like to see if taking a DHA supplement at a dose recommended for heart health will improve brachial artery dilation (relaxation) and help blood pressure. As a second goal the Investigator would like to see if this supplement can delay preterm delivery by improving heart health. In this research study, the Investigator is asking pregnant women with chronic high blood pressure to take Expecta (DHA - Martek Biosciences, now known as DSM Nutritional Lipil) during the last half of their pregnancy until six weeks after they deliver their baby.
