[Interrelation of the rheological properties of the blood and the state of central hemodynamics in patients with a stable form of hypertension].

A study of 44 patients with second-stage essential hypertension (15 males and 29 females) demonstrated a significant positive correlation between packed cell volume and mean arterial BP (r = 0.794; p less than 0.001), packed cell volume and total peripheral resistance (r = 0.
