Background
Black women are four times more likely to die than White women in pregnancy in the U.K. Black women are more prone to Hypertensive Disorders in Pregnancy (HDP). Outside of pregnancy, there are race based differences in the management of hypertension as Calcium-Channel Blockers (CCB) are more effective in reducing blood pressure in Black patients. It is unclear whether these differences in anti-hypertensive management extend to the management of hypertension in pregnancy.
