Abstract
Background. Obesity is associated with the risk of spontaneous preterm birth. Hexoprenaline is the effective and most widely used tocolytic agent, possessing however a significant number of side effects. The effect of hexoprenaline tocolysis on heart rate variability, lipid spectrum and glycaemia level in obese pregnant women remain unexplored.Aim of the research. To study the effect of tocolytic therapy with hexoprenaline on heart rate variability, lipid spectrum and glycemic level in obese pregnant women.Materials and methods. The study included two groups of pregnant women with threatened preterm labor who received tocolysis with hexoprenaline. One group consisted of 68 obese patients, the other – 72 non-obese pregnant women (control group). Patients underwent Holter monitoring. Fasting serum glucose and lipids spectrum were measured before starting tocolytic therapy and after 24 hours of tocolysis.Results. In obese pregnant women with hexoprenaline infusion, the heart rate, the 24-hours number of supraventricular extrasystoles and ventricular extrasystoles during the day are significantly higher. Frequency domain parameters, very low frequency during the day, low frequency at night and 24-hours high frequency were significantly decreased than in control group. After a day of tocolysis in obese pregnant women, the level of total cholesterol, low density lipoproteins, triglycerides, and glucose significantly increases when compared with the results before therapy. For patients in the control group treated with hexoprenaline, only the concentration of high-density lipoproteins is increased.Conclusion. Obesity in pregnant women receiving hexoprenaline tocolysis is associated with low heart rate variability and an increase in the number of cardiac arrhythmias, as well as lipid disorders and an increase in glucose level.

Summary
Влияние токолитической терапии гексопреналином на вариабельность ритма сердца, липидный спектр и уровень гликемии у беременных с ожирением. Влияние токолиза гексопреналином на вариабельность ритма сердца, липидный спектр и уровень гликемии у беременных с ожирением не изучено. Цель исследования: изучить влияние токолитической терапии гексопреналином на вариабельность ритма сердца, липидный спектр и уровень гликемии у беременных с ожирением. Через сутки токолиза у беременных с ожирением уровень общего холестерина, липопротеинов низкой плотности, триглицеридов и глюкозы статистически значимо увеличивается при сравнении с результатами до терапии. Получающих токолиз гексопреналином, ассоциируется с низкой вариабельностью ритма сердца и увеличением количества сердечных аритмий, а также нарушениями липидного спектра и повышением уровня глюкозы венозной крови.
