AIM: Analysis of kind and advance of cardiac disease influence on preterm labour and IUGR rates. MATERIAL AND METHODS: A prospective study on 232 pregnant patients with cardiac malformations, who were hospitalised in Pathology of Pregnancy Unit of OB./ GYN Jagiellonian University Clinic was performed between 1986-1999. Acquired data were compared with results obtained from control group of 424 pregnant patients with physiological course of pregnancy. RESULTS: Results prove of shorter pregnancy duration in patients with higher NYHA classes. Preterm labour rate in patients of NYHA III and IV equals to 31.15% and is 3 times higher than in control group. Patients of NYHA I and II revealed comparable gestational age with control group. CONCLUSIONS: Worse obstetric outcome is characteristic for 3rd and 4th NYHA classes. Intrauterine growth retardation in patients with cardiac malformations occurs after 34 week of pregnancy.
