“…This glycoprotein has also been found to be significantly increased in diabetic patients [27]. Coagulation factor abnormalities including increased levels of fibrinogen, factors VII, IX, X, XII, and von Williebrand factor [28][29][30][31][32][33][34] and decreased antithrombin III and protein C [35,36] are present in these patients. Fibrinolysis is also impaired in this patient population through an increased synthesis of plasminogen activator inhibitor-1 [37][38][39][40].…”

The aim of the study was to determine if a hypercoagulable state that may persist for several months after an acute myocardial infarction may contribute to an increased incidence of stent thrombosis. Primary stenting was performed in 104 consecutive patients with acute myocardial infarction using 147 coronary stents. Twenty‐eight patients (27%) were diabetic and 55 patients (53%) were smokers. A single stent was placed in 63%, two stents in 33%, and more than two stents in 4% of the patients. Procedural success was obtained in 97% of the patients. All stents were deployed using high‐pressure balloon inflation. The reference vessel diameter and minimal lumen diameter after stent deployment were 3.30 ± 0.42 and 3.23 ± 0.42 mm, respectively. Six patients (5.7%) developed stent thrombosis within 1 month after the procedure complicated by reinfarction in five of the six patients. At 1‐month follow‐up, all patients remained alive. On multivariate analysis, independent predictors of stent thrombosis were diabetes mellitus (relative risk [RR] 5.2; 95% confidence interval [CI] 1.8, 25.1), tobacco use (RR 4.5; 95% CI 1.3, 24.5), number of stents: 1 vs. > 1 (RR 3.7; 95% CI 1.1, 15.9), minimal lumen diameter poststent placement (RR 0.03; 95% CI 0.0002, 0.74), and duration of chest pain before intervention (RR 1.1; 95% CI 1.01, 1.25). Stent thrombosis had not been associated with diabetes mellitus and tobacco use previously but is in agreement with the enhanced platelet aggregability, coagulation factor abnormalities, and impaired fibrinolysis characteristic of these patients.
