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: 1. coronary artery disease, coronary artery bypass grafting times three in with left internal mammary artery to left anterior descending artery, saphenous vein to ramus intermedius and saphenous vein to right posterolateral. 2. diabetes mellitus type 2, diagnosed two years ago, on oral hypoglycemic agents. 3. history of pacemaker placement for "three seconds of asystole" in , pacer taken out for repeated staphylococcus aureus infections. medications on admission: enteric coated aspirin 325 mg p.o.q.d., metoprolol 12.5 mg p.o.q.d., lipitor 10 mg p.o.q.d., zestril 5 mg p.o.q.d., flovent 220 mcg two puffs b.i.d., coumadin 7.5 mg p.o.q.d. except for 10 mg p.o.q. friday, glucotrol, and lasix. allergies: isuprel inhaler. history of present illness: the patient was in his usual state of health and developed retrosternal chest pain with shortness of breath and diaphoresis at rest. the patient took three sublingual nitroglycerin without resolution of his ten out of ten chest pain. the patient presented to hospital in and was noted to be in atrial fibrillation with a ventricular rate in the 160s. his systolic blood pressure was approximately 120. his ventricular rate was controlled with intravenous diltiazem. he also received heparin, integrilin and intravenous nitroglycerin. the patient also received a dose of morphine and, despite the therapies, continued to have chest pain. he was transferred by to and received 200 mcg of fentanyl during the flight. upon arrival, the patient was chest pain free. the patient claims that he has had increasing dyspnea on exertion over the past few weeks with climbing a flight of stairs. during that period of time, he also had some occasional retrosternal chest pain, which had been relieved with nitroglycerin. social history: the patient has a remote history of smoking and quit in . he drinks alcohol occasionally and lives at home with his wife. is currently retired, and previously worked as a longshoreman. he has three children. family history: the patient's father died of prostate cancer and his mother died after three strokes. physical examination: on physical examination on arrival, the patient had a temperature of 96.1, heart rate 80, irregularly irregular, blood pressure 107/52, respiratory rate 20 and oxygen saturation 99% on two liters nasal cannula, with a weight of 90 kilograms general: well appearing man in no acute distress. head, eyes, ears, nose and throat: oropharynx moist, no lymphadenopathy, anicteric sclerae. cardiovascular: no jugular venous distention, normal s1 and s2, no s3 or s4, no murmurs or peripheral edema, palpable pulses in extremities. respiratory: unremarkable apart from scattered crackles and wheezes. neurologic examination: alert and oriented times three, no focal deficits. laboratory data: platelet count was 247,000, hematocrit 37.6, and white blood cell count 15.7 with 92 neutrophils, 6 lymphocytes and no bands. partial thromboplastin time 85.3 on heparin, and inr was elevated at 3.2 with coumadin. chem-7 was unremarkable apart from a potassium of 5.9 due to a hemolyzed sample and a bun of 25 and creatinine 1.2. cardiac enzymes showed a ck of 122, mb fraction 10 and troponin 2.2. calcium was 9.4 and magnesium 1.9. electrocardiograms at the outside hospital demonstrated the patient to be in atrial fibrillation with a rate of 150 and a left bundle branch block with st depressions in leads v2 to v6; the st depressions subsequently improved once the patient's rate was brought down to a rate of 100. electrocardiogram on arrival at showed the patient to be in atrial fibrillation at a rate of 90 with a left bundle branch block and no ischemic changes. chest x-ray was normal, without any evidence of congestive heart failure or pneumonia. hospital course: the patient was not catheterized immediately due to his elevated inr. he was continued on the heparin and nitroglycerin and integrilin until his inr decreased. the patient was taken to the cardiac catheterization laboratory on . on catheterization, the patient was found to have a patent left internal mammary artery to left anterior descending artery , occluded saphenous vein to the ramus intermedius and a patent saphenous vein to the right posterolateral. the patient was noted to have a normal circumflex artery and a 30% left main lesion. at the time of cardiac catheterization, the patient was felt to be of higher risk for percutaneous coronary intervention, thus he did not receive any intervention. the patient continued on his heparin and his integrilin and nitroglycerin were weaned off. the patient remained without chest pain during his entire hospital stay. it was noted on the night of admission that the patient had a 15 beat run of nonsustained ventricular tachycardia. the patient was generally asymptomatic after that episode, apart from some mild palpitations and slight lightheadedness. because of this event, the electrophysiology department was consulted. upon discussion with the patient, the patient declined an aicd. it was also felt, due to the patient's refusal to have a pacemaker because of his previous bad experience with pacemakers, that the patient should not be started on amiodarone because of the potential to require a pacemaker afterwards. the patient had his metoprolol and lisinopril titrated upwards during his hospital stay. on , the patient underwent a stress cestimibi study, which demonstrated an area of mild reversibility in his lateral wall. he also had a fixed defect inferiorly. his left ventricular ejection fraction was noted to be at 44%. during the three minutes that he was able to tolerate the modified protocol, the patient experienced some lightheadedness and a drop in his blood pressure from 130 systolic to 100 systolic. following the stress cestimibi study, the patient's options were discussed and the patient elected to proceed with medical management at this time. the patient was discharged to home on in stable condition. follow-up: the patient was instructed to follow up with his primary care physician on for his inr check. he is to be on lovenox 60 mg subcutaneously twice a day while warfarin was being loaded and until further notified by his primary care physician. discharge medications: enteric coated aspirin 325 mg p.o.q.d. metoprolol 75 mg p.o.b.i.d. lisinopril 10 mg p.o.q.d. lipitor 10 mg p.o.q.d. zestril 5 mg p.o.q.d. flovent 220 mcg two puffs b.i.d. albuterol p.r.n. lovenox 60 mg s.c.b.i.d. until notified by primary care physician to stop. lasix 20 mg p.o.q.h.s. glucotrol as directed. , m.d. dictated by: medquist36 procedure: coronary arteriography using two catheters angiocardiography of left heart structures injection or infusion of platelet inhibitor left heart cardiac catheterization diagnoses: coronary atherosclerosis of native coronary artery pure hypercholesterolemia diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled coronary atherosclerosis of autologous vein bypass graft atrial fibrillation paroxysmal ventricular tachycardia unspecified disorder of kidney and ureter family history of ischemic heart disease acute myocardial infarction of unspecified site, initial episode of care 

Answer: The patient is high likely exposed to
