Hypertension is one of the most frequently reported medical disorders of pregnancy and often needs to be managed by antihypertensive drugs. In fact, antihypertensive drugs are in the most commonly used medications during the pregnancy. However, there is still no strong evidence about the appropriate use of antihypertensive drugs for the management of hypertension and about their impact on hypertensive women and their unborn child.

Through this study, we aimed to 1) determine the prevalence and trends of antihypertensive drugs use during pregnancy, 2) identify predictors associated with antihypertensive drugs use during pregnancy, and 3) evaluate the association between antihypertensive drugs exposure and prematurity, low-birth-weight and major congenital malformations. These different aspects of cardiovascular medications use during pregnancy are studied using data from the Quebec Pregnancy Registry.
