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: past medical history: 1. coronary artery disease, status post myocardial infarction in ' 2. dm 3. hypercholesterolemia 4. congestive heart failure 5. left hip fracture in ' allergies: no known drug allergies. history of present illness: the patient is an 81-year-old gentleman with a history of coronary artery disease and diabetes transported to the after continuous chest pain from his rehabilitation center and known myocardial infarction on with enzymes peak, troponin 26.7 and ck 578. the patient was on medical management post his myocardial infarction, however continued to have episodes of chest pain radiating to his throat and back. pain was not relieved by nitroglycerin. the patient had echocardiogram a week prior to his admission, was found to have ejection fraction of 55% (at an outside hospital). also, the patient complained of diarrhea started a few days ago. admission labs: potassium 4.6, bun 32, creatinine 1.9, blood glucose 150. cbc 7.8, hematocrit 32, platelets 210, inr of 1.3. imaging: on electrocardiogram, he had sinus rhythm, no active pt waves, inversions in lead 3. hospital course: on admission, the patient kept complaining of diarrhea and was found to have bright red blood in his stool. on hospital day #2, she was found to have a lower hematocrit at 28.3. the patient continued to complain of diarrhea and was also found to have bright red blood in his stool. the patient was taken to the catheterization lab. findings: lad, septal mild lesion, .............. diagonal, 80% proximal disease of lad after diagonal and diagonal at targets. left circumflex 80% proximal occlusion and 99% at origin of om2. rca 90% proximal lesion. on hospital day #3, the patient continued to complain of diarrhea, was found to have guaiac positive stools. he had received 1 unit of blood and his hematocrit improved to 32.7. gastroenterology consult was requested. on hospital day #4, the patient kept complaining of diarrhea and abdominal discomfort, improved significantly by imodium. by hospital day #5, the patient's diarrhea had subsided. gastroenterology consult concluded that the patient had probably had an upper gastrointestinal bleed which was not active at that time, but still performed an esophagogastroduodenoscopy which showed normal esophagus, stomach, duodenum. the patient was transfused another unit of packed red blood cells for a fall in hematocrit. the patient was taken to an operating room on by dr. where coronary artery bypass x3 was performed with left internal mammary artery to left anterior descending, diagonal coronary artery and reverse saphenous vein graft from aorta to the left anterior descending coronary artery and reverse saphenous vein graft from aorta to the right posterolateral coronary artery. operation went without complication. the patient was transported to the csru in stable condition. on postoperative day #1, the patient received 2 units of red blood cells for low hematocrit. he was successfully extubated, no air leak out of his chest tube, tolerating po's well. on postoperative day #2, the patient remained stable. respiratory status fair, requiring intermittent nebulizers. gastrointestinal - no active bleeding, tolerates po well. ambulates bed to chair. postoperative day #3, the patient was doing well, was weaned off his drips. his chest tubes were discontinued without complications and the patient was transported to the regular floor. postoperative day #3, the patient failed foley trial and foley was put back in. the patient was started on hytrin which he was on prior to surgery. the patient continued ambulating with pt. lasix was increased to 60 mg for edema. postoperative day #4, the patient remained stable. his wires were pulled and cut under sterile condition. the patient continued ambulating with pt. foley was successfully removed, patient urinating. postoperative day #5, the patient is in stable condition, ambulating with pt. no active issues. discharge medications: 1. metoprolol 25 mg po bid 2. docusate 100 mg po bid 3. ranitidine 150 mg po bid 4. aspirin 325 mg po qd 5. tylenol 425 mg 1 to 2 tablets po q4h 6. glipizide 1.25 mg po bid 7. lisinopril 10 mg po qd 8. amiodarone 400 mg qd 9. simvastatin 20 mg po qd 10. lasix 60 mg po bid 11. kcl 20 milliequivalents po q 12 hours 12. terazosin 2 mg po q hs 13. insulin sliding scale, see attached sheet discharge condition: good discharge instructions: the patient is to be discharged into rehabilitation facility. continue to work with pt on ambulation. the patient should come back for postoperative follow up with dr. in six weeks. discharge diagnoses: 1. coronary artery disease, status post coronary artery bypass graft x3 2. diabetes mellitus 3. hypercholesterolemia 4. question of upper gastrointestinal bleed 5. left hip fracture 6. congestive heart failure , m.d. dictated by: medquist36 d: 10:53 t: 11:25 job#: procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery (aorto)coronary bypass of two coronary arteries angiocardiography of left heart structures other endoscopy of small intestine injection or infusion of platelet inhibitor left heart cardiac catheterization coronary arteriography using a single catheter diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome congestive heart failure, unspecified diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled hemorrhage of gastrointestinal tract, unspecified acute myocardial infarction of unspecified site, subsequent episode of care 

Answer: The patient is high likely exposed to
