Hi, Thanks for asking. Based on your query, my opinion is as follows. 1. Anticoagulants are effective for all types of thrombus. Both arterial, venous and even atrial thrombus. 2. The INR range should be maintained between 2-3 at all times, then only anticoagulants will be effective against thrombus. 3. The cholesterol level is too high and needs to be brought down at the earliest. Risk of atherosclerosis and infarction present. You need to be started on statins and fibrates. Non pharmacological therapy includes weight loss, low fat diet, fiber rich diet along with moderate exercises. LDL apheresis can also be done, if it continues to be high. Hope it helps. Any further queries, happy to help again.
