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: in brief, the patient is a 64-year-old male with a significant history for coronary artery disease, status post three myocardial infarctions and also status post five vessel coronary artery bypass graft in ' and status post multiple percutaneous transluminal coronary angioplasties who recently had a catheterization done in and stent placed in . the patient did well until approximately three to four weeks prior to presentation when he began to experience increased dyspnea on exertion. one week prior to presentation, he had chest pain leading to a repeat catheterization at on which showed narrowing of the stent and an ejection fraction of approximately 20%. no intervention was done at that point. on the evening prior to admission, the patient was awoken with chest pressure radiating to the neck anginal equivalent which was relieved by sublingual nitroglycerin. this episode happened three times that night and finally on the fourth re-awakening, the patient presented to the emergency department at and was transferred to the for coronary revascularization. past medical history: 1. coronary artery disease 2. myocardial infarction x3 3. coronary artery bypass graft 4. systemic lupus erythematosus in remission home medications: 1. coreg 6.25 mg po bid 2. lasix 25 mg po qd 3. imdur 30 mg po qd 4. k-dur 10 milliequivalents po qd 5. zestril 2.5 mg po bid 6. multivitamin 7. folate allergies: he has no known drug allergies. physical exam: vital signs: he was afebrile with stable vital signs heart: regular rate and rhythm with a 2 out of 6 systolic ejection murmur heard loudest at the apex. lungs: clear to auscultation. abdomen: soft, nontender, nondistended. extremities: no cyanosis, clubbing or edema. palpable dps bilaterally. pertinent labs: his hematocrit was 44. white count was 8. potassium was 3.9. bun and creatinine was 18 and 0.9. his troponin was 29.7. hospital course: the patient was medically managed initially and then underwent on , coronary artery bypass grafting x2 and a mitral valve annuloplasty with placement of intra-aortic balloon pump. he was transferred to the intensive care unit in relatively stable condition. on postoperative day #1, his balloon pump was weaned and the patient was transferred at 2 units of packed red blood cells. he also began to wean off the ventilator. on postoperative day #1 in the evening, the patient was noted to go into atrial fibrillation, for which he was controlled and started on amiodarone, after which he converted again to normal sinus rhythm. he was extubated during postoperative day #1. on postoperative day #2, the patient was noted to be relatively stable. his balloon pump had already been removed and on postoperative day #3, he was transferred to the floor on lopressor and amiodarone in normal sinus rhythm. on the floor, the patient was noted to do extremely well. physical therapy was consulted and the patient was ambulating extremely well with minimal assistance. on postoperative day #4, he remained afebrile with stable vital signs on lopressor at 25 mg po bid and an amiodarone dose. his left chest tube was discontinued at this time and his right chest tube was removed the following day on postoperative day #5. currently, the patient is postoperative day #6. he remains afebrile with stable vital signs and the patient is ambulating to a level 5 with physical therapy and wishes to be discharged home today. discharge condition: stable discharge diagnoses: 1. coronary artery disease 2. mitral valve regurgitation, status post coronary artery bypass graft x2 and mitral valve annuloplasty secondary diagnoses: 1. coronary artery disease 2. myocardial infarction x3 3. coronary artery bypass graft discharge medications: 1. lopressor 25 mg po bid 2. amiodarone taper 400 mg po tid x4 days, then x7 days, qd x7 days, then 200 mg po qd 3. lasix 20 mg po qd 4. k-dur 20 milliequivalents po qd 5. aspirin 81 mg po qd 6. percocet 1 to 2 po q 4 to 6 hours prn 7. colace 100 mg po bid 8. percocet 9. protonix 20 mg po qd die instructions: the patient should follow up with dr. in approximately three weeks. the patient should also follow up with his primary care doctor, dr. , in approximately three weeks. , m.d. dictated by: medquist36 procedure: (aorto)coronary bypass of two coronary arteries implant of pulsation balloon removal of external heart assist system(s) or device(s) open heart valvuloplasty of mitral valve without replacement diagnoses: systemic lupus erythematosus coronary atherosclerosis of native coronary artery intermediate coronary syndrome mitral valve disorders congestive heart failure, unspecified acute posthemorrhagic anemia cardiac complications, not elsewhere classified atrial fibrillation hemorrhage complicating a procedure 

Answer: The patient is high likely exposed to
