Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: history of present illness: this admission for this 49-year-old male was occasioned by a jump and fall of feet on to his feet and lower back. he was seen and evaluated at an outside hospital, and a computed tomography evaluation demonstrated an l1 burst fracture with 50% retropulsion. the patient was neurologically intact at the outside hospital. he was not started on steroids. he also sustained a right distal radius fracture and complained minimally of back pain here. also, he was on coumadin on admission. past medical history: (past medical history is significant for) 1. mitral valve repair with a mechanical heart valve. 2. coronary artery disease; status post coronary artery bypass graft. 3. hypercholesterolemia. physical examination on presentation: physical examination revealed coma scale of 15. his blood pressure was 144/79. his temperature was 98. the trachea was midline. he had anicteric sclerae. he had bilateral breath sounds that were audible with no chest wall tenderness. his abdomen was soft. the pelvis was stable. rectal examination revealed decreased sphincter tone with heme-positivity. his right wrist and hand were in a splint. upper extremity strength was . motor and sensory examinations were intact. he had weak hip flexors at 3/5 and knee flexors. plantar and dorsal sensation were intact. pertinent laboratory values on presentation: his hematocrit was 26.9 on admission. brief summary of hospital course: he was consulted on by spine/orthopaedics and admitted to the trauma surgical intensive care unit. the l1 burst fracture was noted with some canal impingement, and he continued to be intubated and sedated. he then underwent spinal decompression and right radial pinning. he was awake and alert on postoperative day four. he was transfused as well. on , he was comfortable. an occupational therapy consultation was performed. the patient denied any chest pressure. he also had some visual hallucinations. on day one, it was felt he could have his chest tube withdrawn. on , he had no complaints. a tlso brace was awaited by the team. on , he had a line change over a wire and had an arrest with a decreased blood pressure. he was found to have pulseless electrical activity. cardiopulmonary resuscitation was started according to acls protocol and carried on for 30 minutes. this was discontinued when he failed to respond. discharge status: deceased. , m.d. dictated by: medquist36 procedure: insertion of intercostal catheter for drainage continuous invasive mechanical ventilation for less than 96 consecutive hours enteral infusion of concentrated nutritional substances dorsal and dorsolumbar fusion of the anterior column, anterior technique excision of bone for graft, other bones dorsal and dorsolumbar fusion of the posterior column, posterior technique total ostectomy, other bones repair of vertebral fracture insertion of interbody spinal fusion device closed reduction of fracture with internal fixation, radius and ulna diagnoses: coronary atherosclerosis of native coronary artery aortocoronary bypass status heart valve replaced by other means traumatic pneumothorax without mention of open wound into thorax other closed fractures of distal end of radius (alone) closed fracture of t1-t6 level with unspecified spinal cord injury falling from other man-made structures, undetermined whether accidentally or purposely inflicted cardiac dysrhythmia, unspecified 

Answer: The patient is high likely exposed to
