The purpose of this study is to compare the novel oral anticoagulant apixaban with the standard therapy of warfarin on the size reduction or resolution of left ventricular thrombus over 3 months.
Current treatment for left ventricular thrombus is anti-coagulant or blood thinning agent known as warfarin. Recently at least three novel oral anticoagulant agents were used in the treatment of atrial fibrillation, pulmonary embolism and deep vein thrombosis (DVT).

Novel oral anticoagulant drugs will require no blood taking for INR monitoring, hence less visit and more convenience to patients. Latest studies also showed lesser rate of bleeding as compared to warfarin and hence relatively safer.

Drug Apixaban 5 MG Oral Tablet [ELIQUIS]

Apixaban is licensed for treatment of deep vein thrombosis and pulmonary embolism. Hence, a good study drug for left ventricular thrombosis for possibility of a new indication.

  • Other names: ELIQUIS

Drug Warfarin Sodium

as controlled arm since warfarin is the standard therapy for LV thrombus

  • Other names: Coumadin

warfarin sodium Active Comparator

warfarin daily, dosage according to INR monitor. Aim INR 2-3

apixaban Experimental

Apixaban 5 MG Oral Tablet [ELIQUIS] will be given for randomly selected patients for 3 months.
