Impact of whole blood donation on blood pressure in stage 1 hypertension

The aim of the paper is to study the impact of blood donation on blood pressure in hypertensive donors. Materials and Methods. During 12 months, the authors examined and followed-up 100 frequent whole blood donors, aged 40.3±7.5, with stage 1 hypertension. The donors did not receive any drug treatment for hypertension. The authors also monitored erythrocyte and hemoglobin levels, and 24-hour blood pressure. Statistica 10 software was used for statistical data analysis. Results. The study revealed that the dynamics of blood pressure depended on anemia, which could develop as a result of blood donations. Thus, one year after the 1st blood donation, we observed an increase in 24-hour mean SBP by 4.0 % (p
