title: [Changes in blood pressure and heart rate by an increase in serum estradiol in women undergoing controlled ovarian hyperstimulation].
abstract: The aim of the study was to evaluate changes in blood pressure and heart rate in women undergoing controlled ovarian stimulation (COH) in preparation for assisted reproduction techniques. Material and method: The comparison of blood pressure and heart rate measurements obtained from 5 women (age 35.3 +/- 9.4 years) was performed. The data were collected during the 24-hour ambulatory blood pressure monitoring (ABPM) using Holcard sphygmomanometer CR-07 Aspel S.A. at the beginning and in the last day of short protocol of COH with the use of triptorelin (Decapeptyl 0.1 mg/day--Ferring GmbH) and the total supply of Gonalu F 225 U/day--Merck Serono) and Menotropiny 75j FSH + LH 75 U/day (Merional Imed/lBSA).
  
  
  RESULTS
  During COH the increase in the serum estradiol level was detected (54.03 +/- 9.4 pg/ml at baseline vs. 1128.7 +/- 208.6 pg/ml after COH, p < 0.001). However, there were no differences in SBP and DBP values before stimulation and on the day of its completion. Only the decrease of mean arterial pressure measured by oscillometric method was observed during the study (95.1 +/- 25.3 mmHg vs. 87.6 +/- 27.8 mmHg, p<0.02). Mean arterial pressure measured by oscillometric method decreased in the daytime measurements (98 +/- 27.3 mmHg vs. 92.8 +/- 26.5 mmHg, p<0.05) as well as in the nighttime measurements (84.4 +/- 17.4 mmHg vs. 78.8 +/- 14, 4 mmHg, p <0.05). After COH, the higher heart rate (HR) was measured (in overall ABPM statistics: baseline HR 68.5 +/- 12.8/min vs. 73.6 +/- 13.7/ min after COH, p<0.002 and also in daytime statistics: baseline HR70.8 +/- 13.6 / min vs. 76.3 +/- 15.5 / min after COH, p<0.002).
  
  
  CONCLUSIONS
  The increase in serum estradiol level caused by COH leads to increase in heart rate and reduction in mean arterial pressure measured by oscillometric method. However, short-term increase in serum estradiol during COH is not associated with significant changes in systolic and diastolic blood pressure in women preparing for the in vitro procedure.
