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: this is a 76-year-old male who presented to on after experiencing substernal chest pain at rest on the day prior to admission. sublingual nitroglycerin had provided mild relief, but the pain had recurred overnight. the patient had st depressions on electrocardiogram, but he subsequently ruled out for a myocardial infarction; although, he mildly elevated troponins. the patient continued to have episodes of chest pain while in the hospital not associated with electrocardiogram changes. the patient was transferred to to undergo a cardiac catheterization. past medical history: (past medical history includes) 1. coronary artery disease; status post myocardial infarction in . 2. end-stage renal disease (on hemodialysis on monday, wednesday, and friday). 3. peripheral vascular disease; status post aortobifemoral bypass in . 4. hypertension. 5. chronic obstructive pulmonary disease. 6. hypercholesterolemia. 7. status post left carotid endarterectomy. 8. congestive heart failure (with an ejection fraction of 35% to 40%). allergies: the patient has no known drug allergies. medications on admission: (medications at home included) 1. aspirin 325 mg p.o. q.d. 2. metoprolol 100 mg p.o. b.i.d. 3. norvasc 10 mg p.o. q.d. 4. imdur 120 mg p.o. q.d. 5. zocor 60 mg p.o. q.d. 6. lasix 40 mg p.o. b.i.d. 7. iron sulfate 325 mg p.o. b.i.d. 8. calcium carbonate 1250 mg p.o. t.i.d. 9. nephrocaps one tablet p.o. q.d. physical examination on presentation: the patient presented to the hospital, and on admission he was afebrile, and vital signs were stable. oxygen saturation was 94% on 3 liters nasal cannula. lung examination revealed the patient was clear to auscultation. heart examination had a regular rate and rhythm. hospital course: the patient underwent cardiac catheterization which showed moderate diffuse disease with a 95% lesion of first diagonal. cardiac surgery was consulted on hospital day two and planned for a coronary artery bypass graft by dr. . the patient underwent this procedure on ; coronary artery bypass graft times one for unstable angina. the patient was extubated on postoperative day one. he had hemodialysis as well on postoperative day one. the patient underwent cardiac catheterization again on postoperative day three which showed the left internal mammary artery to left anterior descending artery from the coronary artery bypass graft to be patent. the left anterior descending artery had a 95% lesion at the bifurcation with first diagonal as noted in the prior catheterization. the patient underwent percutaneous transluminal coronary angioplasty and stent of the left anterior descending artery, first diagonal, with rescue left anterior descending artery. the patient had an uncomplicated hospital course except postoperative day six in the afternoon when the patient had a 6-beat ventricular tachycardia noted on the monitor. the patient was seen and examined. he was in no acute distress, and he was asymptomatic with no complaints of chest pain or shortness of breath and was resting comfortably. the patient was afebrile with stable vital signs. the patient was given 2 g of magnesium; of which only 1 g was infused before the intravenous line was lost. the patient was then subsequently given 400 mg p.o. of magnesium oxide. an electrocardiogram was checked, which showed no changes when compared to the previous. electrolytes were checked in order to make sure that any discrepancies were corrected. cardiology was consulted with regard to any further intervention regarding the episode, and it was felt that he did not merit an electrophysiology study. discharge disposition: on postoperative day seven, the patient was afebrile, vital signs were stable, tolerating a regular diet, ambulating well, and with good oral pain control and was felt to be ready for discharge to a rehabilitation facility and was awaiting placement. the patient to be discharged to a rehabilitation facility. discharge instructions/followup: the patient was to follow up with dr. in six weeks. medications on discharge: 1. plavix 75 mg p.o. q.d. 2. calcium carbonate 1250 mg p.o. q.8h. 3. nephrocaps one tablet p.o. q.d. 4. simvastatin 60 mg p.o. q.d. 5. milk of magnesia 30 ml p.o. q.h.s. as needed (for constipation). 6. ibuprofen 400 mg p.o. q.4-6h. as needed. 7. percocet one to two tablets p.o. q.4h. as needed. 8. tylenol 650 mg p.o. q.4h. as needed. 9. enteric-coated aspirin 325 mg p.o. q.d. 10. colace 100 mg p.o. b.i.d. 11. lopressor 75 mg p.o. b.i.d. condition at discharge: condition on discharge was good. discharge status: discharge status was to a rehabilitation facility (to be named at a later date). discharge diagnosis: status post coronary artery bypass graft times one. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass insertion of non-drug-eluting coronary artery stent(s) combined right and left heart cardiac catheterization coronary arteriography using two catheters left heart cardiac catheterization coronary arteriography using a single catheter hemodialysis diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome pure hypercholesterolemia congestive heart failure, unspecified unspecified essential hypertension cardiac complications, not elsewhere classified other chronic pulmonary heart diseases paroxysmal ventricular tachycardia 

Answer: The patient is high likely exposed to
