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: mr. is a 79 year old gentleman who was admitted to hospital after he experienced an abrupt onset of chest discomfort while driving. the patient has a history of previous myocardial infarctions. the patient ruled in for a myocardial infarction at hospital with a peak troponin-i of 3.69. the patient was transferred to for cardiac catheterization and consideration for coronary artery bypass grafting. past medical history: 1. hypertension. 2. hypercholesterolemia. 3. coronary artery disease. 4. status post myocardial infarction in and . 5. history of transient ischemic attack in with no residual. 6. diabetes mellitus, diet controlled. 7. status post colonoscopy in which was negative. 8. history of hematuria with negative cystoscopy in . allergies: the patient has no known drug allergies. social history: the patient is married and lives with his wife, who has disease. the patient is a former smoker, two and one-half packs per day times 30 years, quit in . medications on admission: prilosec, procardia xl, aspirin, lopressor, zestril and zocor; patient unsure of dosages at the time of admission. hospital course: the patient was admitted to for cardiac catheterization. cardiac catheterization showed a left ventricular ejection fraction of 45% with inferior hypokinesis, 95% proximal left anterior descending artery lesion, 80% mid-left anterior descending artery lesion, 80% ramus, 100% right coronary artery and 80% obtuse marginal lesion. cardiac surgery was consulted for consideration of coronary artery bypass grafting. the patient was maintained on intravenous heparin and intravenous nitroglycerin prior to surgery. the patient intermittently complained of episodes of chest pressure and shortness of breath, treated with nitroglycerin. th was taken to the operating room on with dr. for coronary artery bypass grafting times three, left internal mammary artery to the left anterior descending artery, saphenous vein graft to the obtuse marginal one and saphenous vein graft to the posterior descending artery. the patient was transferred to the intensive care unit on a levophed infusion, in stable condition. in the operating room, the transesophageal echocardiogram probe was only passed to the mid-esophagus due to strictures in the distal esophagus. at the end of surgery, the left ventricular ejection fraction was noted to be 55% with improved left ventricular systolic function. the patient developed atrial fibrillation on the early morning of postoperative day number one. after being loaded with amiodarone, the patient was dc cardioverted at 100 joules. the patient converted into sinus rhythm without further ectopy. the patient was subsequently weaned and extubated from mechanical ventilation on postoperative day number one and transferred from the intensive care unit to the floor. the patient again developed atrial fibrillation with controlled ventricular response in the low 100s on postoperative day number two, which was treated with oral lopressor and intravenous magnesium. the patient converted into sinus rhythm. his blood pressure remained stable throughout. the patient began ambulating with physical therapy. the patient's chest tubes were removed on postoperative day number two. on postoperative day number three, the patient's pacing wires were removed. it was decided, because of the patient's home situation, that the patient needed to be discharged to a rehabilitation facility. the patient underwent screening for rehabilitation placement and continued to ambulate with physical therapy. on postoperative day number four, it was noted that the patient had a small amount of serosanguinous drainage draining from the superior portion of his sternal incision. the drainage was cultured and subsequently grew mixed flora, multiple organisms and coagulase negative staphylococcus. the patient was started on intravenous vancomycin and oral levofloxacin. the patient's white blood cell count at the time was 8.7 and he was afebrile. it was also thought that the patient had developed a click upon palpation of his sternum. plastic surgery was consulted. they were unable to reproduce the click, and suggested close observation and continuing antibiotics. the sternal incision was without erythema or signs of cellulitis. by postoperative day number six, there was no drainage evident from the sternal incision. the cardiac surgery team was unable to express any drainage. the patient had continued on his antibiotics. on postoperative day number seven, the patient had been free from drainage from his sternal incision for two days and was cleared for discharge to rehabilitation. condition on discharge: on discharge, the patient had a maximum temperature of 99.3, current 97.7, pulse 64 sinus rhythm, blood pressure 138/75, respiratory rate 18 and oxygen saturation 95% on two liters nasal cannula. the patient's weight is 91.9 kilograms, preoperative weight 93.9 kilograms. neurologically, the patient is awake, alert and oriented times three, grossly intact with no focal deficits. cardiovascular: regular rate and rhythm. extremities: warm and well perfused. lungs: breath sounds clear bilaterally, decreased at left base. abdomen: soft, nontender, nondistended, positive bowel sounds. the patient had a bowel movement on . he is tolerating a diabetic diet. the sternal incision has staples intact without evidence of drainage, no erythema and sternum is stable. the left lower extremity saphenectomy site has steri-strips intact, there is no erythema or drainage noted. laboratory data from : white blood cell count 9, hematocrit 31.5, platelet count 376,000, sodium 139, potassium 4.3, chloride 99, bicarbonate 29, bun 20, creatinine 1 and blood sugar 91; blood sugars have ranged from 90 to 210, patient is covered with a regular insulin sliding scale for hyperglycemia. wound culture from shows mixed flora and coagulase negative staphylococcus. chest x-ray from shows small bilateral effusions, left greater than right, bilateral atelectasis. discharge status: the patient is to be discharged to a rehabilitation facility in stable condition. discharge diagnoses: 1. status post coronary artery bypass grafting. 2. postoperative atrial fibrillation, now in sinus rhythm. 3. postoperative drainage from sternal incision, no without drainage. 4. hypertension. 5. hypercholesterolemia. 6. status post multiple myocardial infarctions. 7. status post transient ischemic attack in , without residual. 8. diabetes mellitus, diet controlled, currently on sliding scale coverage. 9. hiatal hernia. discharge medications: lasix 20 mg p.o.b.i.d. times one week then 20 mg p.o.q.d. times one week. potassium chloride 20 meq p.o.b.i.d. times one week then 20 meq p.o.q.d. times one week. colace 100 mg p.o.b.i.d. zantac 150 mg p.o.b.i.d. enteric coated aspirin 325 mg p.o.q.d. regular insulin sliding scale a.c. and q.h.s., blood sugar 150 to 200 three units, 201 to 250 six units, 251 to 300 nine units. amiodarone 400 mg p.o.q.d. times one month. levaquin 500 mg p.o.q.d. times two days. vancomycin 1 gm i.v.q.12h. times two days. captopril 6.25 mg p.o.t.i.d. zocor 20 mg p.o.q.h.s. ibuprofen 400 to 600 mg p.o.q.4-6h.p.r.n. tylenol 650 mg p.o./p.r.q.4-6h.p.r.n. fop: the patient is to contact dr. office upon discharge from rehabilitation for a follow-up appointment. if the patient remains in rehabilitation on , the patient's staples on his sternal incision may be removed; otherwise, the patient is to return to six for a wound check on to have staples removed. the patient is to follow up with his primary care physician and his cardiologist upon discharge from rehabilitation. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery coronary arteriography using two catheters (aorto)coronary bypass of two coronary arteries angiocardiography of left heart structures left heart cardiac catheterization diagnoses: subendocardial infarction, initial episode of care coronary atherosclerosis of native coronary artery pure hypercholesterolemia tobacco use disorder unspecified essential hypertension diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled cardiac complications, not elsewhere classified atrial fibrillation old myocardial infarction 

Answer: The patient is high likely exposed to
