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: he is a 77-year-old man who had a catheterization at hospital on after having the onset of atrial fibrillation. catheterization at that time revealed no obstructive coronary artery disease, with an ejection fraction of 68%, and mild anterior hypokinesis. on , he had a routine persantine stress test that turned out to be remarkable for a fixed defect of the inferior wall, inferior septum, and inferior apex. the left ventricle was dilated at baseline and became more so post exercise. the patient denied any history of chest discomfort. he does have mild shortness of breath when walking around the house and conducting every day activities. cardiac catheterization showed significant 3-vessel disease. past medical history: his past medical history is significant for congestive heart failure, chronic atrial fibrillation, gout, diabetic neuropathy, silent myocardial infarction. his cardiac risk factors include hypertension and being an ex-smoker. he is also a diabetic. he also has a family history. his father died of a myocardial infarction at age 60. two brothers had coronary artery bypass grafts, and both are alive in their 60s and 70s. past surgical history: he has no past surgical history. review of systems: he denies any recent onset of cerebrovascular accidents, strokes, or transient ischemic attacks as such. the patient had a normal test which is relevant to his harvesting. social history: he lives at home with his wife and family. allergies: he has no known drug allergies. he denies allergies to shell fish and contrast. medications on admission: medications at home included lasix 40 mg p.o. q.d., digitek 0.25 mg p.o. q.d., coumadin 5 mg p.o. q.d. (2.5 mg on tuesday and thursday), allopurinol 300 mg p.o. q.d., glyburide 6 mg p.o. q.d., cozaar 50 mg p.o. q.d., amitriptyline 10 mg p.o. five times per day, nifedipine 60 mg p.o. q.d. pertinent laboratory data on presentation: his laboratories on admission dated , were a white blood cell count of 9.3, hematocrit 45.9, platelets 202. chemistry revealed sodium of 139, potassium 4, chloride 102, bicarbonate 30, blood urea nitrogen 18, creatinine 1.2. hospital course: on , he had a coronary artery bypass graft times four using both a venous and a radial artery graft on the left side. the patient was also diagnosed with new onset congestive heart failure. postoperatively, the patient was transferred to the cardiothoracic intensive care unit and was extubated and transferred to the floor on , on postoperative day one. the patient was in atrial fibrillation rhythm. the patient was started on anticoagulation on , and the patient had rapid atrial fibrillation to 140 range to 150 range which resolved on its own. a peripheral iv was placed in the left antecubital in case further necessitated. the patient was confused at this time but did not have any psychosis. on the morning of again had rapid atrial fibrillation and was given 15 mg of lopressor and bolused amiodarone which controlled his rhythm to be continued on anticoagulation. rehabilitation was seeing the patient, and the patient was fatigued and not completely coherent. rehabilitation continued to see the patient, and on the patient was somewhat more aware of his surroundings. he was still in atrial fibrillation but rate controlled and anticoagulated with inr increasing at this time to 1.4. the patient electrolytes were repleted, and the patient worked with rehabilitation. on , the patient's electrolytes were again repleted. anticoagulation was continued. no significant events occurred, and the patient's inr came back to 1.5. discharge disposition: on , the patient was discharged home in good condition. he was much more aware of his surroundings and interactive with his family. the patient will have at home for some services and monitoring and will follow up with dr. in four weeks as well as with his primary care provider (who is dr. )in who will manage his anticoagulation for his atrial fibrillation. medications on discharge: the patient was discharged home on coumadin titrated to an inr of 2 to 2.5, also on lopressor 50 mg p.o. b.i.d., lovenox 60 mg subcutaneous b.i.d. until therapeutic inr is reached on coumadin ( will arrange for this as well as inr draws). he will also be receiving glyburide 6 mg p.o. q.d., amitriptyline 50 mg p.o. q.h.s. the patient will be given percocet one to two tablets p.r.n. for pain, aspirin 325 mg p.o. q.d., lasix 20 mg p.o. (for him to take as part of his previous medications). the patient was taking 40 mg of lasix preoperatively, potassium chloride 20 meq p.o. b.i.d., and colace 100 mg p.o. b.i.d., ranitidine 150 mg p.o. b.i.d. condition at discharge: the patient was in good condition on discharge. his wounds were healing. no signs of infection were noted. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery combined right and left heart cardiac catheterization coronary arteriography using two catheters (aorto)coronary bypass of two coronary arteries angiocardiography of left heart structures other bypass anastomosis for heart revascularization suture of artery other excision of vessels, upper limb vessels diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome congestive heart failure, unspecified unspecified essential hypertension atrial fibrillation diabetes with neurological manifestations, type ii or unspecified type, not stated as uncontrolled polyneuropathy in diabetes accidental puncture or laceration during a procedure, not elsewhere classified epistaxis 

Answer: The patient is high likely exposed to
