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: mr. is a 63 year-old diabetic who presented to for outpatient cardiac catheterization following a positive stress test. he reports he was in his usual state of health until about two months ago when he started to feel an increase in fatigue and malaise. he did report some dyspnea on exertion especially when climbing hills or stairs, but denied having any chest pain. on he hd a stress test that had to be stopped due to fatigue. he did have depressions in leads 2, 3 and f with occasional supraventricular ectopic beats. he was found to have some left ventricular dysfunction with defects in the anterior wall and apex and inferoseptal and inferior wall hypokinesis. they also found that his ejection fraction was 50%. the patient denies any claudication, orthopnea, edema, paroxysmal nocturnal dyspnea or lightheadedness. past medical history: 1. hypertension. 2. tobacco use. 3. diabetes mellitus. 4. depression. 5. prior bleeding gastric ulcer. allergies: no known drug allergies. medications: 1. aspirin 325 mg po q day. 2. atenolol 25 mg po q day. 3. insulin 70/30 25 units subq b.i.d. admission laboratories: his white blood cell count is 7. his hematocrit 51. bun and creatinine are 20 and 1.0. hospital course: the patient was admitted to the hospital for cardiac catheterization. they found he had severe diffuse three vessel disease with a mildly reduced left ventricular ejection fraction and determined that he was in need of surgical revascularization and was referred to the cardiac surgery service. on the patient was taken to the operating room where he had a coronary artery bypass graft times four. his grafts are left internal mammary coronary artery to left anterior descending coronary artery, saphenous vein graft to diagonal, saphenous vein graft to obtuse marginal one and saphenous vein graft to posterior descending coronary artery. his procedure itself was unremarkable. his cardiopulmonary bypass time was 64 minutes with a cross clamp time of 53 minutes. the remainder of his procedure was unremarkable. postoperatively, he was taken intubated to the cardiac surgery intensive care unit with atrial pacing and a propofol and insulin drips. on the evening of the first postoperative day he was extubated without incident. his chest tubes were discontinued while in the cicu and later that day he was transferred to the hospital floor. the remainder of his hospitalization was unremarkable. the team was consulted to help manage his blood sugar and they provided some patient education as well. the patient's foley catheter was discontinued in a normal fashion on the second postoperative day and his pacing wires were discontinued on the third postoperative day. he required an increase in his lopressor and was up to 50 mg b.i.d. by the time of his discharge. he showed no signs of arrhythmia during his postoperative course. by the fourth postoperative day he had been completely weaned from his oxygen and was ambulating in the hallways independently and was able to ascend a flight of stairs with physical therapy without any difficulty. for this reason we felt that he was safe to be discharged home. therefore on the patient was discharged home in stable condition in the care of his family. he was instructed to follow up with his primary care physician in one to two weeks. in addition, he was instructed to follow up with dr. in approximately four weeks. discharge medications: 1. aspirin 325 mg po q day. 2. lopressor 50 mg po b.i.d. 3. lasix 20 mg po b.i.d. times seven days. 4. lasix 20 milliequivalents po b.i.d. times seven days. 5. colace 100 mg po b.i.d. 6. percocet 5/325 one to two po q 4 to 6 hours prn. 7. insulin 70/30 25 units subq b.i.d. discharge diagnoses: 1. coronary artery disease now status post coronary artery bypass graft times four. 2. insulin dependent diabetes mellitus, partially controlled. 3. hypertension, controlled. , 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 coronary arteriography using two catheters angiocardiography of left heart structures left heart cardiac catheterization diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome pure hypercholesterolemia tobacco use disorder unspecified essential hypertension diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled 

Answer: The patient is high likely exposed to
