Fibrinolytic capacity of arm and leg veins after femoral shaft fracture and acute myocardial infarction.

The local fibrinolytic activity generated in the leg and arm veins during venous occlusion (fibrinolytic capacity) and the systemic fibrinolytic activity were measured at intervals in 11 patients after fracture of the femoral shaft and in 11 patients after acute myocardial infarction. In both groups the fibrinolytic capacity of the leg veins and the systemic fibrinolytic activity were significantly reduced two days after the onset of tissue injury. The fibrinolytic capacity of the arm veins was not altered. These results provide a possible explanation for the predilection of venous thrombosis for the leg veins after accidental trauma and acute myocardial infarction.

Fibrinolytic activity in malignant disease.

Resting fibrinolytic activity and fibrinolytic capacity were compared in 31 patients with malignant disease and in 24 control subjects without malignant disease. Patients with malignant disease had a lower mean fibrinolytic activity: this was particularly marked in those with disseminated disease. In contrast, patients with malignant disease had a fibrinolytic capacity which did not differ from that of the control subjects.

The effect of age upon the coagulation system.

Factors V, VII, VIII, X, XI, and XII of the coagulation system, platelet count, and antithrombin III levels were assayed in 20 healthy volunteers aged 20-40 years and 61 elderly subjects aged 66-96 years whose skinfold thickness was also measured. Factors XI, XII, and antithrombin III levels tended to increase in women and decrease in men while factors X, VII, and V tended to increase in both males and females with advancing years. No age or sex differences were found in platelet counts or factor VIII levels. Factor VIII levels were inversely correlated with obesity in elderly males (r = -0.56, p < 0.005).

The effect of age on the fibrinolytic enzyme system.

Components of the fibrinolytic enzyme system, FR-antigen and fibrinogen, were measured in 20 healthy volunteers aged 20-40 years and in 61 elderly subjects aged 66-96 years. Plasminogen activator levels did not significantly differ between the 20-40 and 66-75 age groups, but were higher in those over 75. Plasminogen showed no change with age except for a fall in those over 75. Fibrinogen, FR-antigen, alpha(1)-antitrypsin, and alpha(2)-macroglobulin all rose with age, but the mean fibrinogen concentration fell in the very elderly.
