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 times twenty years. 2. history of myocardial infarctions times two in and . 3. gastroesophageal reflux disease. 4. hypertension. 5. hyperlipidemia. 6. elbow fracture. allergies: the patient has no known drug allergies. medications: 1. aspirin. 2. prevacid 15 mg q.d. 3. corgard 20 mg po q.d. 4. mevacor 40 mg po q.d. 5. nitroglycerin p.r.n. physical examination: examination revealed the following: blood pressure 130/80, heart rate 72, afebrile. general: the patient was in no apparent distress. heent: examination was within normal limits. there were no bruits. no jvd. chest: examination was clear to auscultation bilaterally. heart: examination revealed regular rate and rhythm without murmurs. abdominal: abdomen was nontender, nondistended, no masses present. extremities: no edema, pulse present bilaterally. laboratory data: laboratory data revealed the following: hematocrit 34, wbc 6.8, platelet count 173,000, sodium 145, potassium 4.6, bun 14, creatinine 1.1, inr 1.9,. chest x-ray performed on showed low lung volumes and retrocardiac opacification, which could indicate atelectasis. hospital course: given the symptoms of chest discomfort and back pain, the patient underwent cardiac catheterization on . the catheterization showed two-vessel coronary artery disease with significant branch-vessel disease in a third artery. left ventricular function was slightly depressed with estimated ejection fraction of 51%. there was an unsuccessful attempt to revascularize the left circumflex due to the inability to cross the lesion. a surgical approach was recommended. on the patient underwent a coronary artery bypass graft times four with left internal mammary artery to left anterior descending coronary artery, reverse saphenous vein graft from the aorta to the right posterior descending coronary artery, reverse saphenous vein graft from the aorta to the obtuse marginal coronary artery, in sequence with the right posterolateral coronary artery. the procedure was without complications. please see the full operative note for details. the patient was transferred to the intensive care unit in satisfactory condition. the patient had a postoperative fever of 101.1. the patient was started on lasix, lopressor, and aspirin. given persistent low-grade fever, blood cultures were obtained, as well as urine culture, which were all negative. on postoperative day #1, the patient was transferred to the regular floor. he remained in stable condition with sinus rhythm. the patient was treated by the physical therapist daily. on postoperative day #4, the patient went into atrial fibrillation. he was symptomatic in that he felt his heart beating away. heart rate was in the 160s. the patient was treated with iv lopressor and the standing dose of lopressor was increased accordingly. the patient eventually converted to sinus rhythm. chest tubes were removed. on postoperative day #6, the patient experienced palpitations while walking with the physical therapist. the heart rate increased to 200 and he was in a rhythm that was most consistent with supraventricular tachycardia. he was treated with iv lopressor. he reverted spontaneously to sinus rhythm. this episode of supraventricular tachycardias occurred one more time and lasted a few minutes. the patient again converted spontaneously into sinus rhythm. no more episodes of supraventricular tachycardia were recorded. the patient remained at least twenty-four hour without any changes in the rhythm. the patient was discharged to home on postoperative day #7 in stable condition. the patient was cleared by the department of physical therapy. he showed good oxygenation levels on room air. he was tolerating a regular diet. the incision was clean, dry, and intact without any significant of infection. condition on discharge: stable. discharge disposition: home. discharge diagnoses: 1. three vessel coronary artery disease status post coronary artery bypass graft. 2. history of myocardial infarction times two. 3. hypertension. 4. hypercholesterolemia. discharge medications: 1. aspirin 325 mg po q.d. 2. prevacid 15 mg po q.d. 3. corgard 20 mg po q.d. 4. mevacor 40 mg po q.d. 5. levofloxacin 500 mg po q.d. for a total course of five days. 6. percocet one to two tablets po q.4h.p.r.n. pain. 7. colace 100 mg po b.i.d. 8. lasix 20 mg po b.i.d. times seven days. 9. potassium chloride 20 meq po b.i.d. times seven days. discharge instructions: 1. the patient is to follow up with his surgeon, dr. in approximately six weeks. 2. the patient is to follow up with his primary care physician, . in approximately one to two weeks. 3. the patient is to follow up with his cardiologist in approximately three to four weeks. , m.d. dictated by: medquist36 procedure: (aorto)coronary bypass of three coronary arteries single internal mammary-coronary artery bypass

Answer: The patient is high likely exposed to
