I was treated with Lovenox and Coumadin and discharged on Xarelto. Does the clot in my heart still pose a threat to my health. I have been on Xarelto for about four days. I was also wondering if I should consider a clotting disorder since I had a blood clot 10 years ago in my leg. I am 57 years old and do not have any other problems with my heart such as A-fib. The only symptom I had was mild shortness of breath. The clots were discovered as an incidental finding on another test.
