Colussi GL, Catena C, Driul L, et al. - This study was sought to explore the associations between calcium metabolism and blood pressure (BP) in preeclamptic women and in a control group of normal pregnancies in the postpartum. Researchers examined a total of 63 consecutive preeclamptic women (age 35 ± 6 years) four weeks after delivery. They obtained clinical and lab information on pregnancy and neonates and measured plasma and urinary calcium and phosphate, plasma parathyroid hormone (PTH) and 25-hydroxy vitamin D [25(OH)D], and performed 24-h ambulatory BP monitoring. The study found common features of secondary hyperparathyroidism in the postpartum. It was shown that preeclampsia and increased PTH levels were both independent factors correlated with elevated BP after delivery, and both might affect the future cardiovascular risk of these women.
