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: social history: history was remarkable for the patient being recently widowed in and certainly has events of clinical depression. allergies: the patient is allergic to dramamine. medications on admission: 1. amiodarone 200 mg p.o.q.d. 2. levoxyl 75 mcg p.o.q.d. 3. nitropaste q 6 hours p.r.n. 4. aspirin 81 mg p.o.q.d. 5. zestoretic 10/12.5 mg q.a.m. 6. lipitor 20 mg p.o.q.d. on , the patient underwent cardiac catheterization when he was admitted to the which showed an ef of 55%. he had mild inferior hypokinesis. there is evidence of the left main coronary artery being long and serpiginous in nature. there was an 80% proximal right coronary artery lesion and 80% proximal lad lesion and serial 40% and 60% stenoses seen in the left circumflex artery. given the patient's significant three-vessel coronary artery disease and subjective symptoms of exertional angina increasing in frequency, he was admitted for unstable angina, cardiac consultation and ultimately for assessment for elective coronary artery bypass graft. he was admitted to the c-med service and in the first couple days of his admission, he had the development of chest pain requiring iv nitroglycerin and heparinization. consultation was carried out to dr. of the cardiothoracic surgery service for an elective cabg, who assessed the patient as appropriate candidate. however, given his paroxysmal atrial fibrillation and hypercholesterolemia and hypothyroidism history, preoperative workup including chest x-ray was completed, which showed the diffuse reticular nodular infiltrate, chronic in nature, certainly evidentiary changes for copd also seen, but no significant pneumothoraces, no bullae identified, and no failure seen. ep consultation was obtained. their recommendations preoperatively were that the patient should be anticoagulated and have beta blockers and amiodarone utilized for rate control. heparin was to be continued with coumadin postoperatively, particularly given this, since the left atrial diameter was about 4.9 as previously measured by echocardiogram in . additional preoperative workup included a bilateral carotid ultrasound, which showed no significant disease, stenoses less than 40%. the patient has never had a history of tia. given the previously mentioned workup, the patient was brought to the operating room on , where he underwent a cabg times three including a lima graft to the lad, right less saphenous vein graft to the right coronary artery and a right radial artery graft to the oblique marginal i. because of the electrophysiology consultation obtained two days preoperatively, it was agreed upon between dr. and the ep service that a left atrial cryoablation and mays procedure would be carried out, which was also done intraoperatively. postoperatively, the patient was intubated on propofol drip and neo-synephrine for blood pressure support. he was brought to the cardiac surgery recovery unit, where he remained intubated. he was transfused one unit of packed red blood cells, postoperatively for a hematocrit of 25 and low filling pressures of 10. the bun and creatinine were noted to be 31 and 1.4. he was being maintained at this time on a milrinone drip at .5, neo-synephrine drip of 3.2, nitroglycerin drip of .5 for the radial artery graft, as well as a propofol drip of 10. the patient was kept in the cardiac intensive care unit. the patient was noted, on postoperative day #2, to go in atrial fibrillation with a rapid ventricular response. this was controlled using iv amiodarone a 1 mg per minute. the milrinone drip was at .5 mcg per hour, neo-synephrine drip was at 3.75 mcg per kilo per minute. the nitroglycerin drip was still at 1.5 and the propofol was utilized for sedation. ultimately, he was retransfused two packed cells on postoperatively day #7 for hematocrit of 26. by postoperative day #3, the patient's fio2 was weaned as tolerated and the chest tubes were removed due to the patient's poor oxygenation. he was kept intubated. he was given dvt prophylaxis and started on heparin therapy and maintained on amiodarone for the atrial fibrillation issues. he had no evidence of clinical bleeding at this time. by postoperative day #4, he was hemodynamically stable. however, he continued to have a slight respiratory and metabolic acidosis. he was started on lopressor for rate control. he was maintained on amiodarone as well. he was switched over from the nitroglycerin drip to imdur for his radial artery graft. ultimately, he was transferred one unit again on postoperative day #4 for hematocrit of 27, with goal of 30. repeat chest x-rays were done during this time. because of the patient's inability to wean from the ventilator, it was seen that he had bilateral fluffy infiltrates with the reticular nodular infiltrates as well, which looked like an acute and chronic process. certainly, the patient had elements of obstructive pulmonary disease by his failure to wean and this made it difficult for him to progress postoperatively. as a consequence, sicu consultation was obtained on postoperative day #6. bronchoscopy was carried out, which showed very thick secretions. he is a smoker. he did grow out evidence of a hemophilus species, which were ultimately treated with a two-week course of levofloxacin. he was noted to have some low-grade temperatures on postoperative day #7, where sputum cultures, chest x-ray, urine cultures, blood cultures, were sent. white count at this time was 13.6, hematocrit 32, platelet count 115, bun and creatinine of 34 and 1.2. he was started on tube feeds and tolerated the tube feeds a this time. ultimately, the patient was extubated by postoperative day #8. he was subsequently transferred to the floor by postoperative day #10. nitrates were decreased to 30 because of low blood pressures. chest x-ray had shown again issues of this bilateral infiltrates with reticular interstitial pattern. the hematocrit at this time was 32. the bun and creatinine were 40 and 1.4. heparin was infusing. by postoperative day #11, however, suffered a bright red blood per rectum bowel movement. he was treated for gi bleed. ng tube lavage from above was negative. hematocrit was 33 and stable. he was given a bowel prep after gi consultation. they stressed the need for colonoscopy, which he underwent on postoperative day #13. this showed evidence of ulceration of the splenic flexure consistent with the clinical picture of ischemic colitis, thought to be secondary to hypotensive episodes he must has suffered during his perioperative course. the hematocrit at this time was 31, bun and creatinine were 25. and .9. general surgical consultation was obtained, which recommended npo iv fluids, broad spectrum antibiotics, which he was given and serial hematocrits. the patient did not have any return of his large bright red blood per rectum bowel movements, but he did have guaiac-positive stools postoperatively. the hematocrit remained stable throughout the entire postoperative course. he was maintained on levaquin and flagyl for broad-spectrum coverage for the presumed ischemic colitis. blood pressure remained stable. he had no more hypotensive episodes. heart rate was well controlled in and out of atrial fibrillation and sinus rhythm. by postoperative day #17, the patient was ambulating at a level 4 with physical therapy assistance. his coumadin therapy had not been restarted. the bun and creatinine were 35 and 1.5. the hematocrit was 36. by postoperative day #18, the patient was deemed appropriate for discharge to rehabilitation. vital signs were 96.0, pulse 62, sinus 116/71. blood pressure was 20. he did have a high o2 requirement postoperatively because of the aforementioned interstitial lung disease. he was 90% room-air saturation on 2 to 4 liters nasal cannula and 79% room-air saturation. discharge labs: as stated. examination was notable for a stable sternum, no evidence of erythema or exudate. the right artery harvest site was clean, dry, and intact with no erythema. the right lesser saphenous vein graft site was also well approximated with no evidence of cellulitis or infection. no peripheral edema was present. lung examination was notable for distant breath sounds bilaterally. heart examination was regular with no murmur. discharge medications: 1. imdur 30 mg p.o.q.d. 2. coumadin 2 mg p.o.q.d. 3. lopressor 25 mg p.o.q.d. 4. lasix 20 mg p.o. q.a.m.q. monday, wednesday, and friday. 5. -dur 20 meq p.o.q.d.q. monday, wednesday, and
