FIELD: medicine. 
     SUBSTANCE: blood is examined for angiogenic factors, namely soluble fms-like tyrosine kinase (sFlt-1) and placental growth factor (PIGF). An angiogenic factor (Ka) is calculated by formula: Ka=sFlt-1/PlGF×10. If Ka is 10 or less, the pregnant woman is stated to require no admission to hospital, no case follow-up; doctor's appointments are scheduled. If Ka falls within the range of 10 to 50, the pregnant woman is admitted to hospital, wherein foetal monitoring, Doppler monitoring are performed; an amniotic fluid index (AFI) is calculated; a therapy aiming at the uterine-placental blood flow improvement is prescribed for 10 days. The amount of infusion makes 400 ml a day. The prescribed preparations are Actovegin, Trental, Instenon, Carnitini chloridum. Control ultrasonography, Doppler monitoring, foetal monitoring, AFI and Ka measurements are performed 2 weeks later. The pregnant woman is discharged from hospital if observing no negative trends. If Ka falls within the range of 50 to 100, the pregnant woman is admitted to hospital, wherein foetal monitoring, Doppler monitoring are performed, and AFI is measured; a therapy aiming at the uterine-placental blood flow improvement is prescribed for 14 days The amount of infusion makes 800 ml a day. The prescribed preparations are Actovegin, Trental, Instenon, Carnitini chloridum. Control Doppler monitoring and foetal monitoring are performed every 3 days; 2 weeks later control Ka is measured. If the trend is positive, the pregnant woman may be discharged from hospital, while no positive trend requires another 2 weeks of the therapy. If Ka is 100 or more, but less than 150, the pregnant woman is admitted to hospital, wherein foetal monitoring, Doppler monitoring are performed, and AFI is measured; a therapy aiming at the uterine-placental blood flow improvement is prescribed for 14 days. The amount of infusion makes not less than 800 ml a day with the same preparations prescribed. Those are added with the preparations for homeostasis correction, including Fraxiparine, Fragmin, Clexane optionally. Control Doppler monitoring and foetal monitoring are daily. Hypamnion also requires measuring control AFI. If a gestational age is less than 34 weeks, respiratory distress syndrome (RDS) should be prevented by administering the preparation Dexon 24 mg according to the schedule: 6 mg every 12 hours 4 times. Control Ka is necessarily measured after 2 weeks of the treatment. If the trend is positive, the pregnant woman may be discharged from hospital, while no positive trend requires another 2 weeks of the therapy. If Ka is 150 or more, and the gestational age is more than 34 weeks, the therapeutic approach is the same, as for Ka being within 100 to 150, control Doppler monitoring, foetal monitoring are performed twice a day, as well as measuring AFI. If observing no foetal weight gain for 2 weeks of the therapy or the functional state of the foetus deteriorates, a Cesarean section is performed. If the gestational age is 34-36 weeks, the therapeutic approach and follow-up are the same as for the gestational age of 34 weeks, except for the prevention of foetal RDS. However, if observing the deterioration of a foetal movement pattern or the functional status of the foetus, a Cesarean section is performed according to the foetal monitoring and Doppler monitoring findings. If the gestational age is more than 36 weeks, and Ka is 150 or more, pre-mature delivery is applied. 
     EFFECT: optimal selection of the therapeutic approach ensured by determining the values reflecting the severity of the cardiovascular disorder directly in the uterine-placental complex and mother's and foetus's compensatory capacities.
