Acute effect of ascorbic acid on fibrinolytic activity

The acute effect of 1 g oral ascorbic acid on serum fibrinolytic activity was studied in 40 adult males. In Group I (healthy adults) administration of ascorbic acid raised the serum level by about 71%, while the fibrinolytic activity increased to a peak of 137% at 6 h. In patients with CAD (Group II) an essentially similar increase in FA was observed. In Group III, simultaneous administration of ascorbic acid with 100 g fat effectively prevented a fall in fibrinolytic activity and actually raised it by 64% above the fasting level.
