Gender peculiarities of blood pressure changes in patients with arterial hypertension and different biorhythms

Background. It is known that the risk of cardiovascular diseases, especially in conditions of increased rhythm of life, psycho-emotional stress, social cataclysms, is associated with various biorhythms, therefore, the study of the influence of various factors on the course of hypertension, taking into account the patient's chronotype, remains relevant. Aim of the study was to analyze the level of blood pressure in patients with arterial hypertension with different chronotypes of the female and male genders. Materials & Methods. The study included 42 patients with diagnosed essential arterial hypertension who were receiving inpatient treatment. The inclusion criterion was patients with arterial hypertension of the 2nd degree. Measurements of Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) (mmHg) were performed using the Korotkoff method. To study the chronotype, we used the validated questionnaire "Composite Scale of Morningness" and scales from official available sources. Results & Conclusions. Arterial hypertension was diagnosed in 33.33% of patients with the evening chronotype, 7.17% with the morning chronotype, and 59.53% with the intermediate chronotype. Taking into account gender, female patients with evening and morning chronotypes and male patients with an intermediate chronotype predominated. Patients with evening chronotype compared to patients with intermediate and morning chronotypes had significantly higher Body Mass Index (BMI) (by 62.69% and 40.33%), disease duration (by 42.68% and 6.23%) and SBP (by 8.21% and 12.21%), respectively. At the same time, BMI in patients with arterial hypertension with an evening chronotype was as close as possible to obesity. The obtained results can be used in the practical work of nurses for the prevention of arterial hypertension by adjusting the duration of sleep and wakefulness and the diet.
