[Effect of diroton on characteristics of 24-hours arterial pressure monitoring in hypertensive patients with polycythemia vera].

AIM

To study the data of 24-h monitoring of blood pressure (MBP) and effects of an ACE inhibitor lisinopril (diroton) in hypertensive patients with polycythemia vera (PV).

MATERIAL AND METHODS

20 patients with arterial hypertension of degree II and III with PV aged 41 to 77 years. Mean duration of AH and PV was 11.8 +/- 2.2 and 2.0 +/- 0.2 years, respectively. Diroton was given as monotherapy in a single morning dose 10-40 mg for 4 weeks. 24-h MBP was made before the treatment and on the 4th week of the treatment. In addition to standard estimations, hour-to-hour double product (DP) was estimated.

RESULTS

After 4 weeks of diroton therapy there was a 12.2%, 9.5%, 25% and 15.4% fall in mean 24-h systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (PP), DP, respectively. A positive effect was registered on variability and 24-h profile of BP. A response was achieved in 85% patients. The target level of mean 24-h blood pressure < 135/85 mm Hg was achieved in 65%, and 10% fall in SBD and/or DBP in 20% patients. ACE inhibitors' side effect--severe dry cough--was not encountered.

CONCLUSION

PV aggravates arterial hypertension. Monotherapy with diroton effectively controls BP in hypertensive patients with PV in a 4-week course intake in a single morning dose and is well tolerated.
