Leon Chesley's Hypertensive Disorders in Pregnancy was initially published in 1978. Four decades later, hypertension complications in pregnancy are still a major cause of fetal and maternal morbidity and death, especially in less developed nations. It is also a leading cause of preterm birth now known to be a risk factor in remote cardiovascular disease. Despite this, hypertensive disorders remain marginally studied and management is often controversial. Chesley's Hypertensive Disorders in Pregnancy, Fifth Edition continues its tradition as one of the beacons to guide the field of preeclampsia research, recognized for its uniqueness and utility. This revision focuses on prediction, prevention, and management for clinicians, and is an essential reference text for clinical and basic investigators alike. It provides a superb analysis of the multiple topics that relate to hypertension in pregnancy, especially of preeclampsia.
