Does elevated total vascular resistance and concentric left ventricular geometry predict adverse maternal and fetal outcomes in women with early mild gestational hypertension?
Elevated total vascular resistance (>1340 dyn seconds/cm5) and concentric left ventricular geometry assessed by echocardiography strongly predict adverse maternal and fetal outcomes in women with early mild gestational hypertension.
Odds Ratio: 64.4 (95% CI 25.9–160.1)
OBJECTIVE: To evaluate the prognostic impact of elevated total vascular resistance (TVR) on the outcome of pregnancy in early mild gestational hypertension (EMGH). DESIGN: Prospective observational study. SETTING: Data collected from women with EMGH referred to the obstetrics outpatient clinic of Tor Vergata University from June 2003 to June 2005. POPULATION: A total of 268 women with EMGH (systolic and diastolic blood pressure BP 140-150 mmHg and 90-99 mmHg, respectively, without significant proteinuria). METHODS: Women had a maternal echocardiographic examination and BP examination within 24 hours of diagnosis. From this, the TVR was calculated and the geometric pattern of the left ventricle assessed. MAIN OUTCOME MEASURES: Fetal/maternal adverse outcomes (pre-eclampsia, preterm delivery, placental abruption, other maternal medical problems, fetal distress, neonatal low birthweight, admittance to neonatal intensive care unit and perinatal death). RESULTS: Ninety-two out of the 268 pregnancies showed adverse outcomes (34.3%). The best independent predictor for the composite of maternal and fetal complications was TVR (OR 64.4, 95% CI 25.9-160.1). The cutoff value was 1340 dyn seconds/cm(5) with a sensitivity and a specificity of 90 and 91%, respectively. Concentric geometry of the left ventricle was also an independent predictor (OR 4.72, 95% CI 1.85-12.04). CONCLUSIONS: Echocardiography could help in identifying women with EMGH who subsequently develop maternal and fetal complications, allowing a classification in high-risk (TVR > 1340 dyn seconds/cm(5), concentric geometry of the left ventricle) and low-risk women (TVR < 1340 dyn seconds/cm(5), nonconcentric geometry of the left ventricle) for adverse outcomes of pregnancy.
Valensise et al. (Fri,) conducted a observational in Early mild gestational hypertension (n=268). Elevated total vascular resistance (TVR) vs. Lower total vascular resistance was evaluated on Composite of maternal and fetal complications (pre-eclampsia, preterm delivery, placental abruption, other maternal medical problems, fetal distress, neonatal low birthweight, admittance to neonatal intensive care unit and perinatal death) (OR 64.4, 95% CI 25.9-160.1). Elevated total vascular resistance was a strong independent predictor for the composite of maternal and fetal complications in early mild gestational hypertension (OR 64.4; 95% CI 25.9-160.1).
