Unstable coronary artery disease [54]Enoxaparin ()
Dalteparin ()
SC UFH ()68Von Willberand factor may have prognostic value, but other biological variables did not predict outcomeCRP, fibrinogen, Von Willberand factor increased over first 2 days despite medical treatment. Enoxaparin (13%) and dalteparin (19%) reduced release of Von Willberand factorOpen label, randomized, clinical trial

ST-Elevated Myocardial Infarction (STEMI) [55]EnoxaparinSCUFH34 (17 in each group)Both heparin and enoxaparin show anti-inflammatory effects in STEMI patientsSerum Amyloid A (: 0.02), CRP (: 0.02), and ferritin (: 0.01) reduced in heparin group. IL-6 (: 0.002), SAA (: 0.009), CRP (: 0.01) were significantly decreased in enoxaparin group. The overall difference between groups was not significantOpen label, randomized, clinical trial

Coronary artery disease [56]DalteparinSCPlacebo555 (285 in control group)Dalteparin reduced coagulation and so Myocardial Infarction but has not inflammatory activityNo effects on IL-6, C-reactive protein and fibrinogen Randomized, double-blind, parallel-group, multicentre trial
