Levels of plasma fibrinogen and d-dimer in patients with impaired fasting glucose.
BACKGROUND
Cardiovascular risk associated with impaired fasting glucose has been examined in various studies with conflicting results. During the last 10 years, several risk markers for atherosclerosis such as fibrinogen and D-dimer have been identified. The present study was designed to evaluate plasma fibrinogen and D-dimer levels in patients with impaired fasting glucose compared with normal subjects and those with type 2 diabetes mellitus.


METHODS
Age-, sex-, and body mass index-matched 30 normal subjects, 30 patients with impaired fasting glucose (fasting glucose 110 to 125 mg/dl), and 30 patients with type 2 diabetes mellitus (fasting glucose >/= 126 mg/dl) were included in the study.


RESULTS
The levels of plasma fibrinogen in patients with type 2 diabetes mellitus, impaired fasting glucose, and normal subjects were 449 (306 - 605) mg/dl, 348 (264 - 468) mg/dl, and 216 (179 - 260) mg/dl, respectively. Patients with impaired fasting glucose had significantly lower plasma fibrinogen levels than patients with type 2 diabetes mellitus (p < 0.05). There were significantly higher plasma fibrinogen levels in patients with impaired fasting glucose than in normal subjects (p < 0.05). The levels of plasma D-dimer in patients with type 2 diabetes mellitus, impaired fasting glucose, and normal subjects were 615 (505 - 768) mg/l, 518 (412 - 664) mg/l, and 424 (356 - 557) mg/l, respectively. Patients with impaired fasting glucose had significantly lower plasma D-dimer levels than patients with type 2 diabetes mellitus (p < 0.05). There were significantly higher plasma D-dimer levels in patients with impaired fasting glucose than in normal subjects (p < 0.05). The levels of plasma fibrinogen and D-dimer were related to fasting glucose in type 2 diabetes mellitus and impaired fasting glucose groups (p < 0.05). We also detected positive correlation between plasma fibrinogen levels and age in study groups (p < 0.05).


CONCLUSIONS
Our data suggest that patients with impaired fasting glucose pose a hypofibrinolytic status and cardiovascular risk, although this was lower than in patients with type 2 diabetes mellitus.
