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: the patient is a 77 year old male with a history of coronary artery bypass graft 18 years ago, with saphenous vein graft to left anterior descending and saphenous vein graft to pda, with a center two years ago. this showed patent left anterior descending graft but with significant other disease. was evaluated by cardiothoracic surgery at that time but was refused a redo coronary artery bypass graft. yesterday, the patient presented to with substernal chest pain similar in character to his prior with some improvement of his pain, but without complete resolution. his pain then recurred and became worse. the patient called 911. in the ambulance, the patient had shortness of breath. in the emergency room, the patient had congestive heart failure on his chest x-ray and examination. he was given lasix and nitroglycerin which gave him relief. his initial ck was negative and his troponin was less than 0.7 which was marginally positive. the patient was started on lovenox. the patient was taken to diagnostic catheterization which showed svg to left anterior descending with a proximal occlusion, svg to pda with 95% lesion and an ejection fraction of 20%. the procedure was complicated by complete heart block when the catheter crossed the aortic valve. the patient got atropine and cpr and had a temporary pacer wire placed and was transferred to for interventional catheterization. here, the patient had a stent placement at svg to his pda in the proximal lesion. this was complicated by distal wire dissection which was treated with two more stents. the patient also had a stent of his 50% distal stenosis in his svg to pda graft. the patient was transferred to the cardiac care unit post procedure with a temporary pacer wire in place. the patient did not require any pacing during the actual procedure. past medical history: 1. coronary artery disease status post myocardial infarction times two, status post coronary artery bypass graft 18 years ago. 2. hypertension. 3. diabetes mellitus. 4. peripheral vascular disease with claudication after walking of a mile. 5. gastroesophageal reflux disease. 6. history of prostate cancer; status post prostatectomy. 7. history of non-melanoma skin cancer. medications: 1. lipitor. 2. zestril. 3. aspirin. 4. isordil. 5. insulin. 6. sublingual nitroglycerin. allergies: the patient gets diarrhea to certain antibiotics but cannot recall the exact ones. social history: the patient lives alone. only family member in the area is a niece whom he only sees about once a year. denies alcohol; quit smoking four years ago. family history: mother with diabetes mellitus; father and brother with myocardial infarctions at ages 58 and 59. physical examination: the patient is afebrile; pulse 92; blood pressure 139/47; saturating 98% on three liters. in general, the patient was comfortable, in no acute distress. heent: dry mucous membranes; no oropharyngeal lesions. extraocular movements are intact. neck: no jugular venous distention, no bruits. heart was regular rate and rhythm without no murmurs. lungs were clear anteriorly. abdomen soft, nontender, nondistended, with normoactive bowel sounds. extremities with no cyanosis, clubbing or edema. two plus pedal pulses. groin with right femoral venous sheath in place. neurologic: alert and oriented times three, moving all four extremities. laboratory: data from the outside hospital: white blood cell count of 10.2, hematocrit of 39.2, platelets 188. inr 1.1. sodium 138, potassium 4.2, chloride 104, bicarbonate 22, bun 31, creatinine 1.5, calcium 8.7, total bilirubin 0.4, alt 55, ast 49, albumin 3.6. ekg showed normal sinus rhythm with rate of 92 and right bundle branch block, q waves in leads iii and f. hospital course: 1. coronary artery disease: the patient is status post non-st elevation myocardial infarction and status post multiple stents with svg to right coronary artery graft. the patient continued on aspirin and statin. the patient to be on plavix for a 30 day course. 2. myocardium: the patient was started on a beta blocker. ace inhibitor was held while in the hospital secondary to an increase in creatinine 3. electrophysiology: status post transient incomplete heart block in the catheterization laboratory. the patient did not require any backup pacing since arriving in the cardiac care unit. his pacer wire was discontinued the following day. the patient tolerated introduction of the beta blocker without difficulty. 4. renal function: the patient's creatinine reached a peak of 2.1 and was down to 1.8 by the time of discharge. the patient to start back on home ace inhibitor on discharge. the patient received mucomyst before and after his catheterization as well as pre and post-catheterization, discharge status: discharged patient to home. condition at discharge: stable. discharge medications: 1. plavix 75 mg p.o. q. day for three days. 2. metoprolol 50 mg p.o. twice a day. 3. aspirin 325 mg p.o. q. day. 4. lipitor. 5. zestril. 6. isordil. 7. ampicillin per home doses. discharge instructions: 1. the patient to follow-up with his outpatient cardiologist, dr. at . , m.d. dictated by: medquist36 d: 16:08 t: 13:34 job#: cc: procedure: insertion of non-drug-eluting coronary artery stent(s) other and unspecified coronary arteriography diagnoses: subendocardial infarction, initial episode of care esophageal reflux unspecified essential hypertension coronary atherosclerosis of autologous vein bypass graft personal history of malignant neoplasm of prostate diabetes mellitus without mention of complication, type i [juvenile type], not stated as uncontrolled 

Answer: The patient is high likely exposed to
