Abstract

Arterial stiffness (AS) and central BP (CBP) are new «target-objects» for Antihypertensive Therapy (AT), but the possibility to correction these parameters on nonmedicament treatment is discussed.

Aim: To research the possibilities of correction of AS and CBP by AT and Continuous Positive Airway Pressure (CPAP) in patients (pts) with severe arterial hypertension (AH) and obstructive sleep apnea (OSA) in prospective, randomized, double-blind, placebo- controlled cross- sectional study.

Methods: Included 44 pts (34men) 55,8±9,4 years with AH II-III gr. and OSA index >30, treated with combination of amlodipine 5–10mg, valsartane 160mg and HCT 25mg. After 3–9 week AT pts were randomized into 2 groups: additional effective CPAP (eCPAP) and CPAP-placebo (P=4 mmH2O). After 3 weeks on CPAP-therapy we carried out the crossover of these groups. At each step of intervention we produced ABPM and CBP measuring (SphygmoCor). AS was estimated by Ambulatory AS Index (AASI) and by carotid-to-femoral pulse wave velocity (PWV).

Results: PWV demonstrated reduction of AS during AT and additional positive effect of eCPAP. Significant reduction of AASI was demonstrated only in cases of combination of AT and CPAP. We estimate additive decreasing of 24h-BP and CBP on eCPAP in comparison CPAP- placebo.

Conclusion: Effective CPAP induced only mild reduction in 24-hBP, but significant decreasing in AS and CBP.
