OBJECTIVE: Polycystic ovary syndrome (PCOS) is a complex endocrine and metabolic disorders, which may contribute to the development of cardiovascular diseases. The aim of our study was to evaluate the association between of 24-hour ambulatory blood pressure measurement (ABPM) and selected biochemical and anthropometric parameters in women with PCOS.

PATIENTS AND METHODS: The study involved 153 Polish, Caucasian women with PCOS hospitalized in the Department of Endocrinology Gynecology from January 2018 to March 2020. All women had stable body mass during the 3-month period. ABPM was performed using a portable lightweight device with oscillometric technology accepted by International Protocol of European Society of Hypertension (ABPM, HolCARD CR-07, Poland).

RESULTS: The first factor taken into consideration was the variability phenotypic subgroups of PCOS on the values of 24-hour ABPM. We revealed that the daytime and night-time systolic and diastolic blood pressure values were significantly higher in phenotype A subgroup than in other subgroups. Moreover, daytime and night-time systolic and diastolic blood pressure value as well as day-time heart ratio value were significantly higher in subgroup with than without hyperandrogenemia. The obese women with PCOS were characterized of the highest value of all night-time measurements among women with PCOS and normal weight, overweight or obesity. In addition, insulin resistance in the PCOS subgroup was associated with lower value of systolic, diastolic blood pressure and both at daytime and night-time heart rate value than in insulin sensitive PCOS subgroup.

CONCLUSIONS: Hyperandrogenemia and obesity were the crucial influencing factors on 24-hour ABPM in the group of women with PCOS. In addition, hypertension, apart from visceral obesity, hyperinsulinemia and insulin resistance, could be considered as component of metabolic syndrome in women with PCOS.
