Goulis, Vasilios kotsisAbstractThe present systematic review and meta-analysis investigated the effects of hydralazine compared with other antihypertensive drugs in maternal, perinatal and neonatal outcomes of pregnant women with hypertensive disorders. Twenty studies with 1283 participants were included. Of them, 626 received hydralazine and 657 other antihypertensive treatments, such as labetalol, nifedipine, ketanserin, diazoxide, urapidil, isradipine and epoprostenol. Women receiving hydralazine had higher heart rate (WMD: 13.4, 95%CI: 0.1 to 26.8 beats/min), increased number of adverse effects (RR: 1.21, 95%CI: 1.01 to 1.45) and gave birth to neonates of lower birthweight (WMD: 13.4, 95%CI: 0.1 to 26.8 beats/min) compared with other antihypertensive treatments at the end of follow-up. When studies, which used antihypertensive agents that are no longer indicated for hypertension in pregnancy, were excluded in the sensitivity analyses, hydralazine found not to have a statistically significant difference compared with labetalol and nifedipine regarding the reduction of maternal blood pressure (WMD: 1.72, 95%CI: -1.47 to 4.9 mmHg for systolic, WMD: 0.26, 95%CI: -1.75 to 2.28 mmHg for diastolic), maternal heart rate (WMD: 13.56, 95%CI: -5.62 to 32.74 beats/min), lo...
