[Gestational arterial hypertension: clinico-epidemiological study].

Aim: Epidemiological assessment of prevalence of blood hypertension (BH) in pregnant women.

Materials And Methods: Blood pressure and urinary protein were measured in 5160 gravidae observed in female consultations in 4 cities of Russia.

Results: BH was found in 1042(20.2%) examinees. Chronic BH was diagnosed in 306 patients. The rest females had gestational BH. Essential hypertension occurred in 174 patients.

Conclusion: A stable rise of diastolic blood pressure above 90 mm Hg is a reliable diagnostic criterion of hypertension in gravidae. Classic proteinuric forms of gestational BH are rare.
