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 68 year old white male has a history of diabetes, hyperlipidemia and hypertension. he was recently diagnosed with three vessel coronary artery disease in and was admitted with unstable angina. the night prior to admission here he had mid sternal chest pain with radiation and diaphoresis in ten minutes. he took nitroglycerin without effect and was awoken with pain later on in the evening. on his way to the emergency room he had nitroglycerin spray and was pain-free on arrival to the emergency room. he was recommended to have a coronary artery bypass graft in and wanted to come back to for his surgery. past medical history: significant for a history of type 2 diabetes, history of peripheral neuropathy, history of retinopathy, history of coronary artery disease with a positive stress test and unstable angina in . he ruled out for an myocardial infarction and a cardiac catheterization revealed three vessel coronary artery disease with an ejection fraction of 70%. he was status post cerebrovascular accident in as well with mild residua of the left hemiparesis, small lacunar hemorrhages. he has a history of hypercholesterolemia and neurogenic bladder. medications on admission: glyburide 5 mg p.o. q. day, lopressor 75 mg p.o. b.i.d., lipitor 10 mg p.o. q. day, aggrenox 25/200 b.i.d., metformin 1 gm b.i.d., zoloft 100 mg p.o. q. day and nitropatch. allergies: he is allergic to bromocriptine. social history: he does not smoke cigarettes, does not drink alcohol and lives alone. family history: unremarkable. physical examination: he is a well developed, well nourished elderly white male in no apparent distress. vital signs, stable, afebrile. head, eyes, ears, nose and throat examination, normocephalic, atraumatic. extraocular movements intact. oropharynx benign. neck was supple with full range of motion, no lymphadenopathy or thyromegaly. carotids were 2+ and equal bilaterally without bruits. lungs were clear to auscultation and percussion. cardiovascular, regular rate and rhythm, normal s1 and s2, no rubs, murmurs or gallops. abdomen was obese, soft, nontender with positive bowel sounds, no masses or hepatosplenomegaly. extremities, without cyanosis, clubbing or edema. femoral pulses were 1+ and equal bilaterally. dorsalis pedis was 1+ on the right and trace on the left. neurological examination was nonfocal. hospital course: he was admitted and seen by neurology. he had a head computerized tomography scan which revealed right small frontal subcortical hypodensity. dr. was consulted and the patient was uncertain as to whether he would like surgery. he eventually consented and on he underwent a coronary artery bypass graft times three with left internal mammary artery to the left anterior descending, reverse saphenous vein graft to the posterior descending artery and obtuse marginal. cross clamp time was 60 minutes, total bypass time was 75 minutes. he was transferred to the cardiac surgery recovery unit in stable condition on neo-synephrine and propofol. he was extubated and had a stable postoperative night. his chest tube was discontinued on postoperative day #2. he did notice some slurred speech and was seen by neurology and they recommended decreasing his pain medications. he also complained of dysphagia. he did have an magnetic resonance imaging scan on postoperative day #3 which was unremarkable. he was transferred to the floor on postoperative day #3. he had a small episode of rapid atrial fibrillation. on postoperative day #4 he was treated with lopressor and amiodarone and converted to sinus rhythm. he continued to slowly improve but required aggressive physical therapy and on postoperative day #7 he was discharged to rehabilitation in stable condition. medications on discharge: lasix 20 mg p.o. b.i.d. for seven days. potassium 20 meq p.o. q. day for seven days. zoloft 100 mg p.o. q. day. glucophage 1000 mg p.o. b.i.d. glyburide 10 mg p.o. b.i.d. colace 100 mg p.o. b.i.d. amiodarone 400 mg p.o. b.i.d. times one week and then decrease to 400 mg p.o. q.d. and then decrease to 200 mg, for one week and then decrease to 200 mg p.o. q. day. dilaudid 2 mg p.o. q. 4-6 hours prn pain. lipitor 10 mg p.o. q. day aggrenox 1 p.o. b.i.d. lopressor 50 mg p.o. b.i.d. laboratory data on discharge: hematocrit 34, white count 9,800, platelets 352, sodium 136, potassium 4.1, chloride 100, carbon dioxide 27, bun 24, creatinine 1.0, glucose 139. follow up: he will be followed by dr. in one to two weeks and dr. in six weeks. discharge diagnosis: 1. coronary artery disease. 2. type 2 diabetes. 3. cerebrovascular accident. 4. atrial fibrillation. 5. hypertension. 6. hypercholesterolemia. dr., 02-358 dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery (aorto)coronary bypass of two coronary arteries transfusion of packed cells diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome acute posthemorrhagic anemia cardiac complications, not elsewhere classified atrial fibrillation diabetes with neurological manifestations, type ii or unspecified type, not stated as uncontrolled polyneuropathy in diabetes iatrogenic cerebrovascular infarction or hemorrhage late effects of cerebrovascular disease, other
