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: history is notable for the following: 1. coronary artery disease. 2. hypertension. 3. hypercholesterolemia. 4. benign prostatic hypertrophy. 5. cholelithiasis. of note: he denies having history of diabetes mellitus, cerebrovascular accident, transient ischemic attack, peptic ulcer disease, peripheral vascular disease, claudication, or bleeding dyscrasias. medications on admission: 1. aspirin 81 mg p.o.q.d. 2. lopressor 25 mg p.o.b.i.d. 3. pravachol 20 mg p.o.q.d. 4. allopurinol 100 mg p.o.b.i.d. 5. niacin 500 mg p.o.b.i.d. 6. lisinopril 20 mg p.o.q.d. 7. hydrochlorothiazide 12.5 mg p.o.q.d. 8. protonix 40 mg p.o.q.d. 9. amiodarone 400 mg p.o.t.i.d. social history: the patient has a remote tobacco use history. he drinks three to four alcoholic beverages per day. he walks several miles a day. family history: the patient's father died in his 90s. mother died in her 60s of a myocardial infarction. he has two sisters that are both status post coronary artery bypass graft. laboratory data: laboratory studies at : white count was 15, platelet count 317,000, bun and creatinine were 22 and 1.8. physical examination: examination revealed the following: temperature 98; heart rate 104, sinus tachycardia; blood pressure 139/77; respiratory rate 16; oxygen saturations 98% on room air. general: in general, he is an older white male in no acute distress. the patient is neurologically awake and oriented times three, moving all extremities and conversant. lungs: lungs were clear to auscultation bilaterally. heart: regular rate and rhythm with normal s1 and s2. there is no murmur. there is no jvd and no bruit. abdomen: soft, nontender, nondistended with normoactive bowel sounds. extremities: warm and well perfused without edema or varicosity. pulses are 2+ throughout. hospital course: the patient was admitted to the cardiac surgery service for preoperative assessment. the remainder of his workup was unremarkable. he remained symptom free in the hospital through the weekend, while awaiting his surgery. on , , the patient was taken to the operating room, where he had a coronary artery bypass graft times two, lima to lad, and reverse saphenous vein graft to om2. the patient tolerated the procedure well. postoperatively, he was taken intubated to the intensive care unit on milrinone and levophed drips. overnight, in the intensive care unit, he was extubated. the following morning he remained on levophed, although the milrinone had been weaned off. during this time, the patient appeared to start to diurese, but the patient was given some additional help with iv lasix. he remained in the intensive care unit until the second postoperative day. overnight, he did have a run of sustained ventricular that required cardioversion. he received an intravenous infusion of amiodarone and the following morning, he resumed his previous oral regimen. he was also continued on oral lopressor and in fact, increased prior to his transfer. because of the patient's problems with ventricular tachycardia, both preoperatively and postoperatively, he will require an implantable internal cardiac defibrillator. he wishes for this to be placed by his cardiologist back in . we have no objection to this and we feel that he is now stable for a postoperative transfer to another acute care hospital. on , the patient was transferred in fair, but stable condition, to for further management. the following day, he is to have an internal defibrillator placed by their cardiology team. the patient is discharged on the following medications: discharge medications: 1. metoprolol 25 mg p.o.q.d. 2. amiodarone 400 mg p.o.t.i.d. 3. lipitor 20 mg p.o.q.d. 4. aspirin 325 mg p.o.q.d. 5. protonix 40 mg p.o.q.d. 6. lasix 20 mg iv q.12h. 7. potassium chloride 20 mg p.o.q.12h. 8. tylenol p.r.n. 9. ibuprofen p.r.n. fog his discharge from , we asked that the patient followup with his primary care physician in approximately two weeks. in addition, we ask that he followup with dr. in approximately four weeks. dr. is available to see him in the clinic. discharge diagnoses: 1. two-vessel coronary artery disease, now status post coronary artery bypass graft times two. 2. sustained ventricular tachycardia, now cardioverted. 3. hypercholesterolemia, treated. 4. benign prostatic hypertrophy. 5. nephrolithiasis. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery other electric countershock of heart (aorto)coronary bypass of one coronary artery diagnoses: coronary atherosclerosis of native coronary artery pure hypercholesterolemia unspecified essential hypertension personal history of tobacco use paroxysmal ventricular tachycardia acute myocardial infarction of unspecified site, initial episode of care 

Answer: The patient is high likely exposed to
