LV Thrombus Pilot Study for Comparing Enoxaparin Vs. Warfarin

Completed · Not applicable

Conditions studied: Coronary Artery Disease, Acute Myocardial Infarction

In brief

To prospectively evaluate the utility of enoxaparin vs. oral warfarin in reduction of echocardiographic indices of LV mural thrombus. The primary outcome is the presence of LV mural thrombus at 3.5 months. The secondary outcome is cost analysis comparing the two arms.
