[Perinatal results in patients with chronic hypertension at the National Institute of Perinatology]. / Resultados perinatales en pacientes con hipertensión arterial sistémica crónica en el Instituto Nacional de Perinatología.

There are many causes of Chronic Hypertension, and all can be present in pregnant women. The literature reports an incidence between 1-3%. The prognosis usually is favorable, if we have an excellent control of blood pressure along pregnancy. But the risks like abruptio placentae, fetal demise or fetal growth restriction have a greater incidence than in the health population, furthermore the superimposed preeclampsia increase notably the perinatal morbidity. The objective of this study is to determine the perinatal outcomes in women with chronic hypertension in the Instituto Nacional de Perinatología. In the study we included 66 patients with chronic hypertension with age between 21-45 years old, and 54.4% had an age between 30-40 years. The evolution time of hypertensive disease was 5 years or less principally (71.2% of the patients).

[Dilated myocardiopathy and pregnancy. Report of 3 cases and review of the literature]. / Miocardiopatía dilatada y embarazo. Informe de tres casos y revisión de la literatura.

Pregnancy in association with dilated cardimyopathy is considered to be a rare entity. The incidence is unknown. The dilated cardiomyopathies (DCM) are defined as diseases of the cardiac muscle without a known cause. Three pregnancies with DCM are reported. In this article the possible hazzards of pregnancy and DCM are discussed, including a review of the literature concerning to diagnosis and management is present.

[Perinatal perspective in heart disease and pregnancy. Review of 1169 cases of pregnancy]. / Perspectiva perinatal de la cardiopatía y embarazo. Revisión de 1169 embarazos.

OBJECTIVE: To determinate the effect of maternal heart disease on pregnancy outcome. METHODS: We reviewed retrospectively 1169 pregnancies in 1093 women with heart disease. 53 women were assisted during 2 pregnancies, ten during 3 and one during 4 pregnancies. All the pregnancies were prenatal and labor assisted at the National Institute of Perinatology, México, D.F. RESULTS: In 705 (60.30%) the heart disease was of rheumatic origin, in 387 (33.10%) congenital and the remaining were a miscellaneous group. Mitral stenosis and mitral regurgitation (42.13%) was the commonest rheumatic cardiac lesion associated with pregnancy. Ventricular septal defect was seen in the 32.81%. 124 women had a heart valve prosthesis (87 mechanical and 40 bioprosthesis [3 women with double heart valve prosthesis]). Intrauterine fetal growth retardation was the commonest complication. (7.52%) in 29 cases were present complications of heart disease in pregnancy. The abortion was present in 30 cases and intrauterine fetal death in 7 cases. There were 977 term pregnancies. The caesarean section rate was 32.5 per cent, most of them were performed for obstetric or fetal indications. The neonatal weight had a average of 2864.4 +/- 526.9 grams. There were eight maternal deaths in this series (five with congenital origin and 3 rheumatic). The incidence of low birth weight was 8.46 per cent. There were two babies born with cardiac congenital malformations.
