[Study of pregnancy with chronic hypertension].

This is a retrospective study of 189 chronic hypertension patients seen at the Discipline of Obstetrics of the São Paulo Medical School at Hospital São Paulo. The data were fed into a computer and several selected variables and established interrelations were run to have a statistical study by means of non-parametric tests. Hypotheses were rejected at a level of 5.0 percent. Results allow to conclude that there is an association of obesity and chronic hypertensive women to obstetrical occurrences such as delayed intra-uterus growth and pregnancy-specific hypertensive disease. With respect to development during pregnancy, a higher number of newborn mortality was observed and correlated to metabolic disorders, infectious diseases, and problems of the respiratory system. However, the authors did not see a high incidence of congenital malformation. All such results lead to the conclusion that the incidence of fetus death, neonatal mortality, and perinatal mortality are five times more frequent in this group than in the control group.
