| Summary: | The aim: To determine the relationship between modified, unmodified cardiovascular risk factors (CRF) and intervisit arterial pressure variability (IAPW) in men of working age with arterial hypertension (AH).
Material and methods. We examined 160 men with uncomplicated AH, among them, 82 patients had high IAPW, and 78 patients – low IAPW. The average age in patients with high and low IAPW did not differ and was 50.65 ± 6.14 and 50.26 ± 6.27 years, respectively (p = 0.689). Indices of IAPW were calculated based on the standard deviation (SD) of measurements of office blood pressure during 4 visits to the clinic. The criterion for high IAPW was the value of systolic arterial pressor (AP) – 15 / 15 mm Hg (day / night), for diastolic AP – 14/12 mm Hg (day / night). The analysis was carried out using standard statistical methods for parametric and non-parametric parameters.
Results. It has been established, that the frequency of both modified and unmodified risk factors is greater in patients with hypertension and high IAPW, than in patients with low IAPW. The presence of obesity (36 of 82 versus 7 of 78; р ≤ 0.0001), family anamnesis (71 of 82 versus 52 of 78; p = 0.004), smoking episodes (62 of 82 versus 12 of 78; р ≤ 0.0001) and alcohol use (24 of 82 versus 2 of 78; p ≤ 0.0001) is significantly more common in patients with high IAPW, than in patients with low level of IAPW. There was a direct correlation between the MBA value and the percentage of 10-year risk of cardiovascular death on the SCORE scale (r = 0.47; p ≤ 0.0001) іn patients with hypertension.
Conclusion. The results of the study confirm the hypothesis that, it is expedient to determine IAPW in patients with AH, as an independent prognostic risk factor for cardiovascular complications.
