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 68-year-old male with a history of hypertension who was admitted to last month with shortness of breath and chest discomfort. studies revealed congestive heart failure and new onset atrial fibrillation. over a 1-week hospitalization, he was diuresed and started on daily lasix. he was also cardioverted and started on coumadin and amiodarone. echocardiogram showed an ejection fraction of 60%, trace aortic insufficiency, and severe 4+ mitral regurgitation. he was discharged home with of hearts monitor which showed a heart rate in the 60s. his beta blocker was discontinued. last week, the patient had one episode of angina for which he took sublingual nitroglycerin with relief. he saw dr. in her office on the day prior to presentation and was scheduled for cardiac catheterization. the cardiac catheterization demonstrated 40% left main disease with stenosis extending into the left circumflex to a greater than 85% narrowing, and into the left anterior descending artery with 70% stenosis. the right posterior descending artery had a 90% lesion. filling pressures were within normal limits. mitral regurgitation on catheterization was noted to be mild. the patient was admitted to the c-med service and cardiothoracic surgery was consulted. past medical history: (past medical history includes) 1. recent congestive heart failure admission. 2. recent atrial fibrillation, status post cardioversion in . 3. abdominal aortic aneurysm, noted to be stable on ct in . 4. cervical stenosis. 5. lumbar spinal stenosis. 6. sleep apnea. 7. gout. 8. irritable bowel syndrome. allergies: no known drug allergies. medications on admission: lasix 80 mg p.o. q.d., coumadin 2.5 mg p.o. q.d., amiodarone 200 mg p.o. q.d., lotensin 15 mg p.o. q.d., protonix 40 mg p.o. q.d., aspirin 81 mg p.o. q.d., proventil and atrovent meter-dosed inhalers p.r.n. pertinent laboratory data on presentation: laboratories on admission included a white blood cell count of 9.6, hematocrit of 44.6, platelets of 190. chem-7 revealed a sodium of 140, potassium of 4.6, blood urea nitrogen of 38, creatinine of 2, and blood sugar of 84. physical examination on presentation: the patient was a white male in no acute distress. breathing comfortably while lying flat and speaking. vital signs revealed 63 in sinus rhythm, blood pressure of 146/96, oxygen saturation 99% on room air. neck revealed no bruits. no jugular venous distention. lungs were clear to auscultation bilaterally. heart revealed a 2/6 systolic ejection murmur heard best with left lying position. right femoral 2+ with no bruit, left femoral was 2+ with no bruit. right dorsalis pedis and posterior tibialis were 2+ bilaterally. no pedal edema. the feet were warm bilaterally. hospital course: the patient was admitted on . the patient was started on heparin, and the coumadin was discontinued prior to surgery. the patient was seen by the cardiothoracic surgery service on and was scheduled for coronary artery bypass graft on . on , the patient underwent a 3-vessel coronary artery bypass graft with left internal mammary artery to the left anterior descending artery, saphenous vein graft to obtuse marginal, and saphenous vein graft to posterior descending artery. the patient was given perioperative vancomycin. the patient did well postoperatively, and on postoperative day one the patient's swan-ganz catheter was removed. the patient was started on a regular diet on postoperative day one and was transferred to the floor. on postoperative day two, the patient's chest tube, foley, and pacing wires were removed. the patient's lopressor was increased to 25 mg p.o. b.i.d. also, on postoperative day two, the patient was seen by physical therapy who thought that he was at a level iii. due to his need to ascend three flights of to live in his apartment, it was suggested that the patient go to a rehabilitation facility for recuperation. the patient was seen again by physical therapy on , and at this time he did a level iv; however, he was still unable to climb , the plan was for him to attend rehabilitation. the patient continued to do well, and on postoperative day four was discharged to rehabilitation on the following medications. medications on discharge: 1. amiodarone 200 mg p.o. b.i.d. times two days; then amiodarone 200 mg p.o. q.d. 2. combivent meter-dosed inhaler 2 puffs q.i.d. and p.r.n. 3. lopressor 25 mg p.o. b.i.d. 4. protonix 40 mg p.o. q.d. 5. albuterol and atrovent nebulizers q.6h. and p.r.n. 6. 20 meq p.o. b.i.d. times seven days. 7. lasix 20 mg p.o. b.i.d. times seven days. 8. oxazepam 15 mg to 30 mg p.o. q.h.s. p.r.n. 9. colace 100 mg p.o. b.i.d. 10. percocet 3/325 one to two tablets p.o. q.4-6h. p.r.n. 11. aspirin 81 mg p.o. q.d. 12. ibuprofen 400 mg p.o. q.4h. p.r.n. 13. tylenol 650 mg p.o. q.4h. p.r.n. die followup: the patient was to follow up with dr. in four weeks and was to follow up with dr. in one week after discharge from rehabilitation. discharge diagnoses: status post coronary artery bypass graft times three. discharge status: the patient was discharged to rehabilitation. condition at discharge: in good condition. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery combined right and left heart cardiac catheterization coronary arteriography using two catheters (aorto)coronary bypass of two coronary arteries angiocardiography of left heart structures diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome mitral valve disorders congestive heart failure, unspecified unspecified essential hypertension gout, unspecified atrial fibrillation unspecified sleep apnea
