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 74-year-old gentleman with a history of diet controlled diabetes and hypercholesterolemia who was admitted to an outside hospital on with complaints of weakness and dyspnea on exertion. the patient had stated that he is in his usual state of health, able to walk miles a day on a treadmill until he noticed 2-3 weeks prior to admission increasing weakness. the patient denies any symptoms of chest pain, pressure or tightness. the patient was admitted to an outside hospital and ruled out for a myocardial infarction. echocardiogram showed an ejection fraction of 60 percent. the patient had a positive esophagogastroduodenoscopy and was transferred to for a cardiac catheterization and subsequently coronary artery bypass grafting. past medical history: diet controlled diabetes mellitus. peripheral vascular disease known abdominal aortic aneurysm status post cerebrovascular accident in with residual left arm weakness. chronic bronchitis. status post right carotid endarterectomy in . status post transurethral resection of the prostate. status post excision of skin cancer on left shoulder. allergies: no known drug allergies. preoperative medications: 1. zestril 10 mg p.o. once daily 2. plavix 75 mg p.o. once daily 3. aspirin 81 mg p.o. once daily 4. hydrochlorothiazide 25 mg p.o. once daily 5. lipitor 20 mg p.o. once daily 6. corgard 20 mg p.o. once daily 7. multivitamin. 8. colace. 9. magnesium supplement. preoperative laboratory data: significant for a creatinine of 1.5. the patient's admission physical examination was otherwise unremarkable. hospital course: the patient was admitted to . he underwent cardiac catheterization which showed a 60 percent proximal left anterior descending lesion, a 50 percent mid left circumflex lesion and 60 percent osteal rca lesion. the patient was referred to dr. for coronary artery bypass grafting. as part of the preoperative workup, a neurology consultation was obtained to evaluate his risk of stroke. the preoperative neurologic evaluation which included an mra of the brain and carotid and vertebral arteries which showed a remote right frontoparietal infarct with chronic microvascular infarction involving the periventricular white matter. the mra of the carotid and vertebral arteries showed mild, diffuse decrease in flow signal involving all of the left sided intracranial vessels including the left internal carotid artery with diffusely diminished flow signal within the left common carotid artery and the left internal carotid artery with irregularity and focal narrowing demonstrated just inferior to the bifurcation in the left common carotid artery. the patient was cleared for being taken to the operating room. the patient was taken to the operating room on with dr. and underwent a coronary artery bypass graft times four with left internal mammary artery to the left anterior descending, saphenous vein graft to rca, saphenous vein graft to om3 and a y-graft saphenous vein graft to lm2. the patient tolerated the procedure well and was transferred to the intensive care unit in stable condition. the patient was weaned and extubated from mechanical ventilation on the first postoperative night. approximately 20 minutes after extubation, the patient developed difficulty breathing and stridor which subsequently required reintubation. the patient remained intubated on postoperative day one, and on postoperative day two, the patient was weaned and extubated from mechanical ventilation successfully without any evidence of stridor. the patient began diuresis. post extubation, the patient had some mild confusion which was treated with haldol and subsequently resolved. on postoperative day number three, the patient developed atrial fibrillation which was controlled with amiodarone. the patient was started on a heparin infusion for anticoagulation. on postoperative day number four, the patient was transferred from intensive care unit to the regular part of the hospital. the patient had been started on lopressor, captopril and lasix. the patient was evaluated by physical therapy, and it was determined that the patient would benefit from a stay at rehabilitation facility. the patient's pacing wires were removed without incident, and on postoperative day number eight, the patient was cleared for discharge to rehabilitation. condition on discharge: temperature maximum 98.1. pulse 65 and sinus rhythm with an episode of atrial fibrillation with heart rate of 90-100. blood pressure 110/42. respiratory rate 18. room air oxygen saturation 97 percent. the patient had a chest x-ray on which showed small bilateral pleural effusions, flattened diaphragms, no evidence of congestive heart failure or consolidation. neurological: the patient is awake, alert and oriented times three. the patient has existing left upper extremity weakness which is unchanged. cardiovascular: heart is irregularly irregular with no rub or murmur. respiratory: breath sounds are clear anteriorly. posteriorly, the patient has scattered rhonchi without any sputum production. gastrointestinal: positive bowel sounds. soft, nontender and nondistended. the patient was tolerating a regular diet. extremities: warm and well perfused. there is trace edema. sternal incision is open to air. steri-strips are intact. there is no erythema or drainage. the arm is stable. the lower extremity vein harvest site is clean and dry. there is no erythema or drainage. discharge medications: 1. percocet 5/325 1-2 tablets p.o. every 4-6 hours p.r.n. 2. imdur 60 mg p.o. once daily. 3. zantac 150 mg p.o. once daily. 4. lopressor 50 mg p.o. b.i.d. 5. amiodarone 400 mg p.o. once daily. 6. captopril 25 mg p.o. t.i.d. 7. lasix 20 mg p.o. once daily. 8. potassium chloride 20 meq p.o. once daily. 9. lipitor 20 mg p.o. once daily. 10. coumadin. the patient is to have 5 mg on , . the patient is to have a pt and inr checked on , and coumadin dose is to be adjusted for a goal inr of 2 to 2.5. 11. aspirin 325 mg p.o. once daily. 12. albuterol metered dose inhaler two puffs p.o. every 6 hours. 13. atrovent metered dose inhaler two puffs p.o. every 6 hours. the patient is to be discharged to rehabilitation facility in stable condition. the patient is to follow up with dr. in weeks. he is to follow up with dr. in weeks. he is to follow up with dr. in weeks. , m.d. procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours (aorto)coronary bypass of three coronary arteries single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery coronary arteriography using two catheters left heart cardiac catheterization insertion of endotracheal tube diagnoses: coronary atherosclerosis of native coronary artery pure hypercholesterolemia unspecified essential hypertension diabetes mellitus without mention of complication, type ii or unspecified

Answer: The patient is high likely exposed to
