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 50 year old man with a past medical history significant for coronary artery disease, status post myocardial infarction as well as a minimally invasive coronary artery bypass grafting with the left internal mammary artery to the left anterior descending by dr. in . past medical history: past medical history is also significant for diabetes mellitus and hyperlipidemia. allergies: the patient has no known drug allergies. medications on admission: the patient was on no medications at the date of admission. social history: the patient has no known history of tobacco or alcohol use or abuse. hospital course: the patient is transferred from an outside hospital for cardiac catheterization with complaints of chest pain at rest. these were pains that were reportedly similar to the symptoms he experienced with his prior myocardial infarction. he took aspirin and sublingual nitroglycerin times one at home without relief. at the outside hospital, he was started on heparin and intravenous nitroglycerin and was given intravenous lopressor times two as well as a standing p.o. dose of 50 mg which made the patient pain free. cardiac catheterization was performed on , which revealed normal left main coronary artery, 100% proximal disease of the left anterior descending, 90% proximal stenosis of the left circumflex with 90% mid and long 70% om1, as well as 100% midstenosis of the right coronary artery. the left internal mammary artery to left anterior descending was patent with a small atretic h graft of the gastroepiploic artery connecting the left internal mammary artery to the left anterior descending which had a long 70% lesion at the site of anastomosis. left ventriculography revealed an ejection fraction of 40%. the patient underwent coronary artery bypass grafting redo times three on , with a y graft of the left internal mammary artery to left anterior descending and left radial to obtuse marginal as well as a saphenous vein graft to the right coronary artery. total cross clamp time for the patient was 102 minutes. total cardiopulmonary bypass time was 121 minutes. the patient was transferred in stable condition, being av paced at 80 beats per minute to the cardiac surgery recovery unit on nitroglycerin and neo-synephrine. postoperative day one 24 hour events included a successful extubation without complication. the patient with a low grade temperature of 99.9, however, tachycardic in sinus rhythm at 107 beats per minute with an index of 3.26 and a cvp of 5.0, oxygen saturation 96% on five liters nasal cannula. white blood cell count and hematocrit stable as well as the patient's renal function. aside from the tachycardia, the patient's physical examination was unremarkable. the plan was to continue the patient's nitroglycerin for the radial artery and to change the nitroglycerin to imdur to p.o. today. the plan was to transfer the patient to the floor. on postoperative day two, 24 hour events included transfer to the floor the day prior. on physical examination, the patient only with complaints of mild back pain due to a fall that occurred without injury the day prior. the patient still with a low grade temperature of 99.4 with a temperature maximum of 99.9, oxygen saturation 91% in room air. physical examination remained unchanged. the plan was to monitor the patient's pain control, to discontinue the patient's chest tube and to continue with the current drug regimen. postoperative day three, the patient was still in sinus tachycardia in the 90s to 100s, oxygen saturation 93% in room air, with no complaints of pain. the patient was discharged to home in stable condition. medications on discharge: 1. colace 100 mg p.o. twice a day. 2. ranitidine 150 mg p.o. twice a day. 3. aspirin 325 mg p.o. once daily. 4. imdur 60 mg p.o. once daily. 5. metoprolol 25 mg p.o. twice a day. 6. percocet one to two tablets p.o. q4hours p.r.n. pain. condition on discharge: the patient was discharged home in stable condition. discharge instructions: the patient is to contact dr. for a follow-up visit in four weeks. discharge diagnosis: coronary artery disease, status post redo coronary artery bypass grafting times three. , 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: subendocardial infarction, initial episode of care pure hypercholesterolemia diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled gout, unspecified coronary atherosclerosis of unspecified type of vessel, native or graft aortocoronary bypass status old myocardial infarction 

Answer: The patient is high likely exposed to
