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: the patient is a 62-year-old white male with a past medical history significant for coronary artery disease, chronic obstructive pulmonary disease, and hypercholesterolemia. the patient originally presented with unstable angina at the end of . at that time, the patient experienced sudden onset of shortness of breath, dyspnea, and lightheadedness. he eventually presented to an outside hospital, which revealed possible inferior st changes. a cardiac catheterization was performed, which revealed three vessel coronary artery disease. the patient was then transferred to to be evaluated for a possible coronary artery bypass graft. on the day of admission, the patient was feeling well, denying any chest pain or shortness of breath. he came in on an intravenous heparin drip. past medical history: 1. hypertension 2. coronary artery disease 3. chronic obstructive pulmonary disease 4. anxiety 5. obesity past surgical history: no significant surgical history allergies: penicillin outpatient medications: 1. paxil 2. effexor 3. lipitor 4. aspirin physical examination: the patient's temperature was 97.2, heart rate 72, blood pressure 128/77, oxygen saturation 94% on room air. he was in no apparent distress. his head, eyes, ears, nose and throat examination was within normal limits. there was no jugular venous distention. there were no bruits. he was clear to auscultation, although decreased breath sounds throughout. his abdomen was obese, nontender, nondistended, with no hernia or masses palpable. he had decreased bowel sounds. extremities showed no edema, were warm and well perfused. he had palpable dorsalis pedis and posterior tibial pulses bilaterally. laboratory data: hematocrit 41.1, white blood cell count 8.0, platelets 268. pt 12.8, ptt 43.7, inr 1.1. glucose 79, bun 15, creatinine 1.0, sodium 141, potassium 4.0. chest x-ray obtained on showed no evidence of acute cardiopulmonary disease. hospital course: the patient was admitted to cardiac surgery. at the time, given three vessel disease on cardiac catheterization, it was thought that a surgical solution would be the best approach. on , the patient underwent coronary artery bypass graft x 3, with left internal mammary artery to the left anterior descending, reverse saphenous vein graft to the obtuse marginal, branch of the circumflex and reverse saphenous vein graft of the right coronary artery. the patient tolerated the procedure well. there were no complications. please see the full operative report for details. the patient was transported to the cardiac intensive care unit postoperatively. the patient remained intubated. the swan-ganz catheter was in place. the patient had chest tubes in place. on the same day, the patient was extubated without incident. the patient was encouraged pulmonary toilet. on postoperative day one, the patient remained in the intensive care unit. he was tolerating ice chips without complaints of nausea. he remained neo-synephrine dependent despite additional fluid, with systolic blood pressures in the 90 to 100 range. his bun, creatinine and white cell count remained stable, as did his hematocrit. physical therapy was consulted and worked with the patient daily. the patient was consequently transferred to the regular cardiac floor. he remained stable. his pacing wires were discontinued. his chest tubes were first put to water seal and then removed as well. he continued to be diuresed and beta blocked as per protocol. he was on aspirin. the patient continued to make significant progress with physical therapy. he was eventually cleared by physical therapy to go home. the patient remained in sinus rhythm. condition on discharge: stable discharge disposition: home discharge diagnosis: 1. status post coronary artery bypass graft x 3 2. coronary artery disease 3. hypertension 4. hypercholesterolemia 5. obesity 6. anxiety 7. depression discharge medications: 1. fenofibrate 160 mg by mouth once daily 2. venlafaxine xr 150 mg by mouth three times a day 3. albuterol nebulizers as needed 4. celexa 40 mg once daily 5. neurontin 800 mg by mouth twice a day 6. colace 100 mg by mouth twice a day as needed 7. milk of magnesia as needed 8. percocet one to two tablets by mouth every four to six hours as needed 9. ibuprofen 400 mg by mouth every six hours as needed 10. enteric-coated aspirin 325 mg by mouth once daily 11. ranitidine 150 mg by mouth twice a day 12. potassium chloride 20 meq by mouth twice a day for ten days 13. lasix 20 mg by mouth twice a day for ten days 14. lopressor 12.5 mg by mouth twice a day discharge instructions: 1. the patient is to follow up with his surgeon, dr. , within four weeks. 2. the patient is to follow up with dr. , his primary care physician, the next week. 3. the patient was instructed to follow up with a cardiologist within the next three weeks. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass
