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 is a 75 year old female a bioprosthetic mitral valve for rheumatic heart disease, with known chronic atrial fibrillation, anticoagulated. the patient traumatized her right thigh two days prior to admission and noted a small, bruised area which has increased in size and was associated with increasing pain. the patient was evaluated in the emergency room. she received if and p.o. morphine sulfate for pain control with episode of hypertension. hematocrit was 31.9 and dropped to the 26.0. her thigh hematoma continues to increase and the thigh is tense with bloody bullae. the patient received four units of ffp, five mg of vitamin k and two liters of intravenous fluid. the patient was transferred to the vascular service for continued care. past medical history: rheumatic heart disease; status post mitral valve times three; last valve was in . history of congestive heart failure with ejection fraction of 25 to 30%, in . p-mibi on the showed an ejection fraction of 69%. hypertension. hypercholesterolemia. atrial fibrillation, rate controlled. femoral-femoral bypass in . allergies: penicillin. inderal. (manifestations unknown.) medications: coumadin 6 mg h.s. indivasc 7.5 mg twice a day. atenolol 50 mg q. day. lasix 80 mg q. day. potassium chloride. aspirin. lipitor 10 mg q. day. social history: the patient lives in with her grandson. physical examination: vital signs: 96.8; 108/89; 65; 18; 100% on two liters. general: appearance is pleasant, white female, sleepy and in no acute distress. head, eyes, ears, nose and throat: unremarkable. neck examination is without carotid bruits, lymphadenopathy or jugular venous distention. chest examination shows diminished breath sounds on the right base with an irregular tachycardia and a 2/6 systolic ejection murmur heard at the right lower sternal border. abdominal examination is unremarkable with bowel sounds present. the right thigh is large, firm hematoma with bloody four cm bullae with a 1+ palpable dorsalis pedis pulse with no edema. laboratory data: laboratory work in the emergency room included hematocrit of 32 which dropped to 26 and then to 24, requiring transfusion and reversal. bun 31; creatinine 1.2. potassium of 4.3. electrocardiogram showed atrial fibrillation with no acute changes. hospital course: the patient remained n.p.o. she was seen by the vascular service. recommendations were that she would require a hematoma evacuation. the patient desaturated secondary to volume overload. blood gases were 7.23, 77, 80 and 34. prior to intubation, chest x-ray showed elevated right hemi-diaphragm but no congestive heart failure. she also was started on neo-synephrine to maintain her systolic blood pressure. she was transferred to the unit. dr. was made aware of the patient's admission and clinical status and they followed her during the perioperative period. on , the patient underwent incision and drainage and evacuation of hematoma of the right thigh. she tolerated the procedure well. - drains times two were placed. we drained more than a liter of hematoma fluid. she was transferred back to the surgical intensive care unit for continued care. postoperative day number one, she remained intubated. there were no overnight events. low grade temperature of 100.2. cardiac output was 2.9; pap of 58; m-31 cep 14. blood gases were 7.43, 40, 99, 27 and 1. hematocrit stabilized to 28.8. bun of 34; creatinine of 1.5. inr was 1.7 with a ptt of 34.5. the patient's dopamine was weaned and continued with diuresis. her respiratory support was simv to c-pap for anticipating extubation. the patient remained in the surgical intensive care unit. cardiology felt that the patient's atrial fibrillation was well controlled and that she was maximized on her medical therapy. the patient was extubated on postoperative day number two. wound was described as indurated. - drain had minimal drainage. heparin drip was initiated without bolus to maintain a goal ptt of 60 to 80. antibiotics were discontinued. dressings were silvadene, adaptic, kerlix, ace to the leg twice a day. the patient was transferred to the surgical intensive care unit for continued monitoring and care. the patient continued to do well. her diet was advanced as tolerated. her platelet count was monitored because of thrombocytopenia which stabilized at 79,000. swan was discontinued on postoperative day number four. her coumadin was reinstituted with a goal inr of three and she was transferred to the regular nursing floor. cefazolin was begun for erythematous changes of the thigh. physical therapy began to work with the patient. cefazolin will be continued and the two - drains were removed. the patient was seen by physical therapy who felt that she would require rehabilitation placement, prior to returning to home. postoperative day number five, the foley was discontinued. the patient had no difficulty voiding post removal. case management was requested to begin rehabilitation screening and the - drains were removed. the remaining hospital course was unremarkable. the patient could be discharged from the vascular surgery standpoint when cardiology was satisfied with her inr. goal inr was 3.0 to 3.5. she should continue keflex 500 mg for a total of seven days post discharge and follow-up with dr. in one weeks time. , m.d. 2914 dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours insertion of endotracheal tube other incision with drainage of skin and subcutaneous tissue suture of unspecified blood vessel diagnoses: abnormal coagulation profile congestive heart failure, unspecified acute posthemorrhagic anemia other pulmonary insufficiency, not elsewhere classified anticoagulants causing adverse effects in therapeutic use contusion of thigh injury to other specified blood vessels of lower extremity striking against or struck accidentally by furniture without subsequent fall 

Answer: The patient is high likely exposed to
