Haemorheological and haemodynamic changes in hypertensive diabetics

We measured plasma fibrinogen concentration (PFC), relative plasma viscocity (RPV), and arterial blood flow at the calf, ankle and great-toe in hypertensive and normotensive patients with diabetes compared with non-diabetic age and sex-matched control subjects. Blood flow after reactive hyperaemia at the ankle was also measured. PFC was measured by a clot-weight procedure. RPV was measured by capillary viscometery, and blood flow by venous occlusion plethysmography.
