Serum calcium and magnesium levels in women presenting with pre-eclampsia and pregnancy-induced hypertension: a case-control study in the Cape Coast metropolis, Ghana.

Background: Hypertensive disorders of pregnancy are important causes of morbidity and mortality. The levels of calcium (Ca2+) and magnesium (Mg2+) in pregnancy may implicate their possible role in pregnancy-induced hypertension. This study assessed serum Ca2+ and Mg2+ levels in women with PIH (pregnancy-induced hypertension) and PE (pre-eclampsia), compared to that in normal pregnancy.
