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 an 82-year-old man with unstable angina transferred from hospital for coronary artery bypass grafting. the patient was recently diagnosed with coronary artery disease, catheterized at an outside hospital, which showed 70-80% left main, severe proximal left anterior descending coronary artery and mid left anterior descending coronary artery with a 90% ramus, 100% right coronary artery, and proximal circumflex coronary artery lesion with an ejection fraction of 30%, admitted to the outside hospital with increasing chest pain, put on a heparin drip and nitroglycerin paste. he underwent cardiac catheterization and was then transferred to for coronary artery bypass grafting. past medical history: 1. coronary artery disease. 2. diabetes. 3. hypercholesterolemia. 4. benign prostatic hypertrophy. 5. hypertension. allergies: the patient has no known drug allergies. medications: 1. aspirin 325 q.d. 2. norvasc 2.5 q.d. 3. lopressor 37.5 b.i.d. 4. lipitor 20 q.d. 5. lisinopril 10 q.d. 6. nitroglycerin paste two inches q. 8 hours. 7. doxazosin 4 mg q.h.s. 8. folate 1 mg q.d. 9. glucovance 1.25/500, one tablet q.a.m., two tablets q.p.m. 10. protonix 40 q.d. laboratory data: glucose 174, sodium 140, potassium 4.0, bun 18, creatinine 1.0, white blood cell count 8.6, hematocrit 34, platelet count 190, inr 1.2. physical examination: on admission heart rate was 68 and sinus rhythm, blood pressure 102/60, respiratory rate 20, alert and oriented x 3, moved all extremities. lungs: clear to auscultation bilaterally. cardiac: regular rate and rhythm, s1 and s2, no murmur. abdomen: soft, nontender, nondistended. extremities: warm and well perfused. hospital course: the patient was seen by cardiothoracic surgery and scheduled for coronary artery bypass grafting. on the patient went to the operating room. please see the operating room report for full details. in summary, at that time he had coronary artery bypass grafting x 3 with a left internal mammary artery to the left anterior descending coronary artery, saphenous vein graft to obtuse marginal, saphenous vein graft to ramus. he tolerated the surgery and was transferred from the operating room to the cardiothoracic intensive care unit. at the time of transfer the patient had a mean arterial pressure of 66. he was av paced at a rate of 88 beats per minute. he had dobutamine at 2.5 mcg per kg per minute, neo-synephrine at 0.8 mcg per kg per minute, and propofol at 25 mcg per kg per minute. the patient did well in the immediate postoperative period. he remained hemodynamically stable. his anesthesia was reversed and sedation discontinued, however the patient was slow to awaken following discontinuation of his sedatives, and was therefore ventilated during the overnight period after his surgery. on postoperative day one the patient was extubated in the early am. all cardioactive iv medications were discontinued. his pa line was discontinued. he remained hemodynamically stable throughout the day and on postoperative day two his chest tubes were removed and he was transferred to the floor for continuing postoperative care and cardiac rehabilitation. over the next several days with the assistance of the nursing staff and physical therapy staff, the patient's activity level was increased. his medications were adjusted, and on postoperative day four it was decided that the patient was stable and would be ready for transfer to a rehabilitation center the following morning for continuing care. at the time of anticipated transfer, the patient's physical examination is as follows: temperature 98.6, heart rate 76 and sinus rhythm, blood pressure 130/70, respiratory rate 16, o2 saturation 99%, weight preoperatively 74.8 kg, at discharge 68.9 kg. laboratory data showed a white count of 10.2, hematocrit 32.2, platelet count 167, sodium 138, potassium 4.1, chloride 100, co2 30, bun 19, creatinine 0.7, glucose 90. physical examination was alert and oriented x 3, moved all extremities, followed commands. lungs were clear to auscultation bilaterally. cardiac was regular rate and rhythm, s1 and s2 with no murmur. sternum was stable, incision with staples open to air, clean and dry. abdomen was soft, nontender, nondistended, normal active bowel sounds. extremities were warm and well perfused with trace edema. right calf incision with steri-strips open to air, clean and dry. discharge medications: 1. furosemide 20 mg q.d. x 7 days. 2. potassium chloride 20 meq q.d. x 7 days. 3. aspirin 325 q.d. 4. protonix 40 q.d. 5. glucovance 1.25/250 one tablet in the am, two tablets in the pm. 6. captopril 25 mg t.i.d. 7. doxazosin 4 mg q.h.s. 8. percocet 5/325 one to two tablets q. 4-6 hours p.r.n. condition on discharge: good. discharge diagnoses: 1. coronary artery disease status post coronary artery bypass grafting x 3 with left internal mammary artery to the left anterior descending coronary artery, saphenous vein graft to obtuse marginal and saphenous vein graft to ramus. 2. diabetes mellitus. 3. hypertension. 4. benign prostatic hypertrophy. 5. hypercholesterolemia. 6. hypertension. follow up: the patient is to have follow up with dr. in four weeks and follow up with dr. in three to four weeks. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery (aorto)coronary bypass of two coronary arteries diagnoses: coronary atherosclerosis of native coronary artery pure hypercholesterolemia
