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 64 year old gentleman with known three vessel disease referred by dr. for evaluation of positive stress test and recent exertional angina. past medical history: 1. hypertension times fifteen years. 2. type 2 diabetes mellitus. 3. hypercholesterolemia. 4. sleep apnea on cpap. 5. prostatic enlargement. 6. cervical arthritis. medications on admission: 1. metoprolol 25 mg p.o. b.i.d. 2. isordil 20 mg p.o. t.i.d. 3. norvasc 10 mg p.o. q.d. 4. zoloft 50 mg p.o. q.d. 5. lipitor 10 mg p.o. q.d. 6. univasc 50 mg b.i.d. 7. glucophage mg b.i.d. 8. hydrochlorothiazide 25 mg p.o. q.d. 9. terazosin 50 mg p.o. q.d. 10. aspirin 325 mg p.o. q.d. 11. nph insulin 22 units q.h.s. allergies: no known drug allergies. the patient has no allergies to dye or shellfish. social history: the patient denies use or abuse of alcohol, tobacco or recreational drugs. physical examination: on admission, vital signs revealed blood pressure 138/66, heart rate 99, oxygen saturation 96% in room air. general appearance is that of a well appearing, well dressed gentleman consistent with stated age of 64 years. neck - no carotid bruits. the lungs are clear to auscultation bilaterally. the heart is regular rate and rhythm, no murmur. the abdomen is soft, nontender, nondistended. palpable dorsalis pedis and posterior tibial pulse bilaterally. femoral pulses are both palpable without bruits. there is no pedal edema. both feet are warm to touch equally. laboratory data: cardiac catheterization from , showed left main 40 to 50% occlusion, left anterior descending 40% occlusion in origin, 60 to 70% proximal occlusion, mid and distal left anterior descending no occlusion. diagonal 80% stenosis at the origin of the small upper pole and there is diffuse disease in the mid segment in the large lower pole up to 90%. left circumflex 50%, om 30 to 40%. proximal right posterior descending artery 70% at the origin, 95% midportion. ejection fraction was noted to be 45%. stress echocardiogram - the patient exercised for nine minutes on protocol experiencing left sided chest pain and had 1.5 to 2.0 millimeter horizontal st segment depressions laterally. echocardiogram showed inferoapical hypokinesis at rest with worsening septal and apical hypokinesis with exercise consistent with left anterior descending ischemia. his ejection fraction was calculated to be 55 to 60%. hospital course: the patient was admitted to on , and he went to the operating room with dr. and had coronary artery bypass graft of four vessels, left internal mammary artery to left anterior descending, saphenous vein graft to om, saphenous vein graft to posterior descending artery, saphenous vein graft to posterolateral artery. please see previously dictated operative note for more details. the patient tolerated the procedure well and remained intubated as he was transferred from the operating room to the cardiac surgery recovery unit. the patient was transported to the cardiac surgery recovery unit on a neo-synephrine drip. postoperative day number one, his chest tubes were removed but still required neo-synephrine to maintain his pressure. he as also on an insulin drip. postoperative day number two, he was transfused one unit of packed red blood cells for hematocrit of 21.2. by the end of postoperative day number two, he had been weaned off all his cardioactive drips. he was stable to be transferred to the patient care floor. on postoperative day number three, his foley was removed. for the duration of the hospital course, his hematocrit was stable. by postoperative day number four, he was ambulating to level four and his foley had been out and he had voided and his pacer wires were removed. the patient was set to be discharged to home on postoperative day number five when the nurse noted a scant amount of drainage at the inferior aspect of his wound. because of the patient's history of diabetes mellitus, decision was made to watch the patient overnight to see if there was any further drainage. there was no further drainage since 9:00 a.m. on postoperative day number five. the patient was discharged to home with services on postoperative day number six. condition on discharge: stable. discharge disposition: to home. discharge medications: 1. metoprolol 25 mg p.o. b.i.d. 2. lasix 20 mg p.o. q.d. times one week. 3. potassium chloride 20 meq p.o. q.d. while on lasix. 4. colace 100 mg p.o. b.i.d. 5. enteric coated aspirin 325 mg p.o. q.d. 6. glucophage mg p.o. b.i.d. 7. nph insulin q.h.s. for glucose less than 200, he will take 15 units, for glucose greater than 200, he will take 25 units. 8. ibuprofen 400 mg p.o. q6hours p.r.n. 9. percocet one to two tablets p.o. q4-6hours p.r.n. pain. 10. acetaminophen 650 mg p.o. q4-6hours p.r.n. discharge diagnosis: status post coronary artery bypass graft times three on . , 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 diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome pure hypercholesterolemia unspecified essential hypertension diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled unspecified sleep apnea 

Answer: The patient is high likely exposed to
