[Study of blood viscosity and fibrinogen as a guide to the therapy of atherosclerotic peripheral arteriopathy].

Of the many blood parameters now regarded as useful in the study of arteriopathy particular importance is attached to viscosity and fibrinogen levels. Changes in viscosity lead to changes in flow and the supply of O2 to the tissues, while fibrinogen alterations frequently accompany or precede atherosclerosis, since they both encourage the intravascular deposition of fibrin and help to modify viscosity. The pharmacological correction of such changes is discussed.
