Abstract
Research objective: to evaluate arterial stiff ness indicators and its correlation with parameters of 24-hour ambulatory blood pressure monitoring (ABPM) in women with newly diagnosed breast cancer (BC).Material and methods: a prospective cohort study in 158 women aged 27 to 64 years with a median age of 45.4 years and newly diagnosed BC at stage IIA–IIIB before chemotherapy was conducted. The first group included 109 patients with normal or high-normal office blood pressure (BP), and the second group included 49 women with previously diagnosed stage 1– 2 essential hypertension (EH) with low or moderate cardiovascular risk. All patients underwent indirect arteriography and ABPM. Results. According to ABPM data, “masked” arterial hypertension (MAH) was diagnosed in 54 (49.5%) women in the fi rst group. In patients with MAH, the mean daily level and diastolic BP time index exceeded the corresponding indicators in EH, and the magnitude of the morning rise in systolic BP was significantly lower. In 35.4% of the examined patients with EH, the pulse wave velocity (PWV) was increased, and in 17.4% it was pathological. With MAH, these changes were recorded in 28.5% and 14.1% of cases, respectively. The odds ratio showed that in women with normal BP, the probability of an increase in PWV >10 m/s increased by 1.6 times, and in the presence of comorbidity with MAH and EH, it increased by 2.2 and 2.4 times, respectively. The risk of an increase in central systolic BP >125 mm Hg and pulse BP >60 mm Hg was highest in patients with EH.Conclusion: Among young and middle-aged women with newly diagnosed BC, a significant number of cases of MAH and EH are detected, which determines the need to evaluate arterial stiff ness and daily BP profiles before starting antitumor therapy.
