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 66 year old, white male patient with a history of coronary artery disease. he is status post myocardial infarction in and also has a past medical history of diabetes. he presented on the morning of to an outside hospital after having two to three days of intermittent chest pain which did radiate to his left arm and was relieved with sublingual nitroglycerin. in the emergency department, at the outside hospital, he was placed on intravenous nitroglycerin. he ruled in for myocardial infarction with a troponin of 0.6 and a cpk of 107. he was transferred to on for cardiac catheterization. this revealed a left ventricular ejection fraction of 30% and significant three vessel coronary artery disease. he was referred for coronary artery bypass graft. past medical history: 1. status post myocardial infarction in . 2. status post pilonidal cyst removal. 3. status post tonsillectomy and adenoidectomy. 4. status post bilateral cataract extraction in . 5. non insulin dependent, diet-controlled diabetes type ii. medications: 1. aspirin 325 mg p.o. q. day. 2. sublingual nitroglycerin prn. allergies: percodan, causing nausea and vomiting. social history: the patient does have a 90 pack year smoking history; however, he quit 19 years ago and remote heavy alcohol history but none in many recent years. the patient is married and lives with his wife and he is retired. physical examination: on admission, physical examination was unremarkable. the patient's cardiac catheterization revealed significant three vessel coronary artery disease with decreased left ventricular ejection fraction of 30%. the patient was taken to the operating room on where he underwent coronary artery bypass graft times four with a left internal mammary artery to the left anterior descending, saphenous vein to obtuse marginal one, saphenous vein to diagonal and saphenous vein to posterior descending artery. postoperatively, the patient was transported from the operating room to the cardiac surgery recovery unit in good condition on epinephrine, neo-synephrine and propofol drips. the patient was weaned from mechanical ventilation and extubated on the night of surgery. on postoperative day number one, he remained on low doses of epinephrine and neo-synephrine drips for continued hypotension with an adequate cardiac output. he was on a nasal cannula with good oxygen saturation. over the course of the next 24 hours, the patient was weaned off of his epinephrine, remained on low dose neo-synephrine for some persistent hypotension. he also had atrial fibrillation on the morning of postoperative day number two which was treated with intravenous amiodarone and the patient has subsequently converted to normal sinus rhythm. on postoperative day number two, , the patient had his mediastinal chest tubes removed. the left pleural tube remained in place. due to fairly high output, although it was mostly serous in nature, he still had a significant volume of drainage from that left pleural tube and it was thought best to leave it in until the drainage had decreased. the patient was subsequently transferred out of the cardiac surgery recovery unit to the telemetry floor on postoperative day number three. the patient began ambulation and continued to progress adequately from a physical therapy standpoint. subsequent chest x-ray revealed a small left apical pneumothorax with an intermittent air leak in the pleura-vac from the left chest tube which had remained in. therefore, the chest tube was left in for a few more days. ultimately, the air leak resolved. the volume of pleural drainage significantly decreased and the chest tube was removed on , postoperative day number five. the patient has had no subsequent atrial fibrillation. it was known upon removal of the chest tube that he did have a small left apical pneumothorax at that time and since the chest tube had been removed approximately 24 hours after the chest tube was discontinued, a subsequent chest x-ray revealed a very small left apical pneumothorax, possibly a bit smaller in size than previous. the patient has remained on room air with good oxygen saturation and he is being discharged home today on , postoperative day number six, status post coronary artery bypass graft. his condition upon discharge today is as follows: he is afebrile. he is in normal sinus rhythm with a rate of 76. his blood pressure is 130/70; respiratory rate is 20 with a room air oxygen saturation of 97%. neurologically, the patient is grossly intact. he has no apparent neurologic deficit. on pulmonary examination, his lungs were clear to auscultation bilaterally. his coronary examination was regular rate and rhythm with no murmur noted. his abdomen is slightly obese, positive bowel sounds. he is nontender and nondistended. the patient states that he has had a bowel movement today. he has trace bilateral pedal edema. his sternal and right leg saphenectomy incisions are clean and dry with no drainage, no erythema and the patient is discharged to home today with . his most recent laboratory values are from yesterday, , which include a white blood cell count of 6.3, hematocrit of 29.3 and platelet count of 288,000. sodium of 135; potassium of 4.1; chloride of 98; c02 30; bun 16; creatinine 0.8; glucose 132. discharge medications: 1. lasix 20 mg p.o. twice a day times one week. 2. potassium chloride 20 meq p.o. twice a day times one week. 3. colace 100 mg p.o. twice a day. 4. zantac 150 mg p.o. twice a day. 5. enteric coated aspirin 325 mg p.o. q. day. 6. plavix 75 mg p.o. q. day. 7. amiodarone 400 mg p.o. twice a day times one week and then decrease to 200 mg p.o. twice a day times one week and then decrease to 200 mg p.o. q. day. this is to continue at this dose until discontinued by the patient's primary cardiologist, dr. . 8. lopressor 25 mg p.o. twice a day. 9. dilaudid 2 mg p.o. q. four hours prn for pain. 10. ambien 5 mg p.o. q h.s. prn sleep. the patient is to follow-up with dr. , his primary care physician, two to three weeks. the patient is to follow-up with dr. , his cardiologist, in two to three weeks. he is to follow-up with dr. , cardiac surgeon in four weeks. discharge diagnoses: 1. coronary artery disease. 2. postoperative atrial fibrillation. 3. type ii diabetes mellitus. discharge condition: good. , m.d. dictated by: medquist36 procedure: (aorto)coronary bypass of three coronary arteries single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery angiocardiography of left heart structures left heart cardiac catheterization coronary arteriography using a single catheter diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled atrial fibrillation iatrogenic pneumothorax surgical operation with anastomosis, bypass, or graft, with natural or artificial tissues used as implant causing abnormal patient reaction, or later complication, without mention of misadventure at time of operation 

Answer: The patient is high likely exposed to
