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: allergies: prednisone / benadryl attending: chief complaint: chest pain major surgical or invasive procedure: four vessel coronary artery bypass grafting(left internal mammary to left anterior descending, vein graft to ramus, vein graft to diagonal, vein graft to right coronary artery). mitral valve replacement utilizing 27 millimeter pericardial valve. history of present illness: this is a 85 year old male who was recently admitted to with chest pain. he ruled in for an mi at that time. workup revealed multivessel coronary artery disease. he was subsequently transferred to the for operative care. his past medical history is significant for known mitral valve prolapse with moderate to severe mitral regurgitation. an echocardiogram in was notable for mvp with severe mitral regurgitation, trace tricuspid regurgitation and an lvef of 65%. past medical history: mitral valve prolapse with severe mitral regurgitation, hypertension, hyperlipidemia, chronic renal insufficiency, history of deep vein thrombosis(right lower extremity), history of bladder cancer, history of rectal cancer - s/p ileocolonic loop colostomy social history: quit tobacco in . denies etoh. family history: denies premature coronary disease. physical exam: vitals: bp 134/78, p 58, r 16, sat 99% on 2l general: elderly male in no acute distress heent: oropharynx benign neck: supple, no jvd, no carotid bruits chest: lungs clear bilaterally heart: rrr, normal s1s2, holosystolic murmur noted abd: soft, nontender, nondistended, normoactive bowel sounds ext: mild rle swelling noted, no pitting edema pulses: 2+ femoral, 2+ radial, decreased pt and dp neuro: nonfocal pertinent results: 04:39am blood wbc-8.6 rbc-3.11* hgb-9.7* hct-28.4* mcv-91 mch-31.3 mchc-34.3 rdw-15.1 plt ct-82* 04:39am blood glucose-95 urean-69* creat-2.6* na-137 k-3.7 cl-105 hco3-22 angap-14 04:39am blood calcium-8.1* phos-4.4 mg-2.6 08:30am blood heparin dependent antibodies- negative brief hospital course: mr. was admitted and underwent extensive preoperative evaluation. a carotid ultrasound showed only minimal plaques in the internal carotid arteries while a lower extremity ultrasound confirmed chronic dvt in right lower extremity. an echocardiogram revealed mitral valve prolapse with 3+ mitral regurgitatiion. his overall left ventricular systolic function was normal. the dental service was consulted and recommended several tooth extractions prior to operative intervention. this took place on without incident. he otherwise remained relatively stable on intravenous heparin. he complained on intermittent angina which was relieved with sublingual nitro. cardiac enzymes remained flat and no ekg changes were noted. his preoperative course was otherwise uneventful and he was eventually cleared for surgery. on , dr. performed a mitral valve replacement(27 mm ce pericardial valve) and four vessel coronary artery bypass grafting. surgery was uneventful. after the operation, he was brought to the csru. he remained sedated and intubated for several days with a prolonged pressor requirement. his renal function concomitantly declined, initially requiring natricor to improve diuresis. he quickly transitioned to intravenous lasix. a routine chest x-ray was notable for a small right apical pneumothorax for which a new chest tube was inserted. over several days, he slowly weaned from inotropic support. he was eventually extubated on pod#3 and awoke neurologically intact. all chest tubes were eventually removed without futher complication. his platelet count dropped as low as 64k on pod#4. an hit assay was checked, returning negative. his hemodynamics eventually stablized with gradual improvement in urine output. on postoperative day five, he transferred to the sdu. a brief period of paroxysymal atrial fibrillation was noted. he otherwise remained mostly in a normal sinus rhythm with first degree av block. k and mg levels were monitored closely and repleted per protocol. the remainder of his post-operative course was unremarkable. he was discharged to rehab on post-op day #7 in stable condition. medications on admission: zestril 5 qd, lipitor 10 , 81 qd, cipro 250 qd discharge medications: 1. furosemide 20 mg tablet sig: one (1) tablet po daily (daily). tablet(s) 2. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). 3. potassium chloride 10 meq capsule, sustained release sig: two (2) capsule, sustained release po daily (daily). 4. atorvastatin 10 mg tablet sig: one (1) tablet po daily (daily). 5. pantoprazole 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po q24h (every 24 hours). 6. propoxyphene n-acetaminophen 100-650 mg tablet sig: one (1) tablet po q4-6h (every 4 to 6 hours) as needed. 7. aspirin 81 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po daily (daily). 8. erythromycin 5 mg/g ointment sig: one (1) ophthalmic qid (4 times a day). 9. lorazepam 0.5 mg tablet sig: one (1) tablet po hs (at bedtime) as needed. discharge disposition: extended care facility: -

Answer: The patient is high likely exposed to
