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 54-year-old gentleman who presented with a 2-day history of epigastric burning off and on associated with nausea, vomiting, and sweating who presented to an outside hospital. electrocardiogram had nonspecific changes. the epigastric pain was initially rated as and reduced to with sublingual nitroglycerin and morphine. the patient was started on a heparin infusion, integrilin, and aspirin. the initial set of cardiac enzymes were positive for myocardial infarction, and the patient was transferred to for cardiac catheterization. past medical history: 1. hypertension. 2. status post cerebrovascular accident in without residual. 3. gout. 4. history of ethanol use; the patient drinks three to four beers per day and at least one glass of vodka per day. 5. a 20-pack-year smoking history. medications on admission: (preoperative medications included) 1. verapamil-sr 360 mg by mouth once per day. 2. atenolol 100 mg by mouth once per day. 3. lisinopril 20 mg by mouth once per day. 4. viagra by mouth as needed. allergies: concise summary of hospital course: the patient was transferred from to for cardiac catheterization. catheterization revealed a left ventricular ejection fraction of 60%, a left ventricular end-diastolic pressure of 8, mild inferior hypokinesis, 80% distal left main lesion, 60% left anterior descending artery lesion, subtotal occlusion of obtuse marginal, and 60% to 70% right coronary artery. an intra-aortic balloon pump was placed in the catheterization laboratory, and cardiac surgery was consulted. the patient was transferred to the coronary care unit in stable condition. on hospital day two, the patient had a transthoracic echocardiogram which showed an ejection fraction of 50% to 55%, mild left ventricular systolic dysfunction, with inferolateral akinesis, and trivial mitral regurgitation. the patient remained stable on his heparin and integrilin drips and intra-aortic balloon pump. the patient was taken to the operating room on by dr. for a coronary artery bypass graft times three with left internal mammary artery to left anterior descending artery, right internal mammary artery to posterior descending artery, and saphenous vein graft to obtuse marginal. please see the operative report for further details. the patient was transferred to the intensive care unit in stable condition with an intra-aortic balloon pump, on amiodarone for atrial ectopy, and nitroglycerin drip for his internal mammary arteries. the patient was extubated from mechanical ventilation on postoperative day one. the patient's intra-aortic balloon pump was removed on postoperative day one without difficulty. the patient began ambulating with physical therapy and was quickly able to progress to ambulating in the intensive care unit. the patient was transferred from the intensive care unit to the floor on postoperative day two. the patient's nitroglycerin drip was transitioned to imdur. the patient was started on lopressor and lasix, which he tolerated well. on postoperative day two, the patient was able to ambulate 400 feet with physical therapy without difficultly. on postoperative day three, the patient's chest tubes and pacing wires were removed without difficulty. the patient's medications were transitioned to his home medications of atenolol and lisinopril. on postoperative day three, the patient was cleared by physical therapy for discharge to home; ambulating 500 feet and climbing one flight of stairs without difficulty. however, on postoperative day three, it was noted that the patient had a moderate amount of serosanguineous drainage from the distal portion of his sternal incision. the sternum was stable at this time. a chest x-ray at that time showed that the wires were intact. there was no pleural effusion. the sternal incision was cleaned and dressed with a dry sterile dressing. the patient continued to have a fair amount of drainage. on postoperative day four, the patient had a low-grade fever with a temperature of 101 degrees fahrenheit. the patient was pan-cultured, and subsequent cultures were negative. the patient also had an episode of atrial fibrillation which spontaneously converted in a sinus rhythm. the patient was given an additional dose of lopressor and re-bolused with amiodarone. over the next 24 hours, the patient had several episodes of atrial fibrillation; however, the patient had no episodes of atrial fibrillation after the morning of on postoperative day four. on postoperative day four, the patient was started on levofloxacin empirically for the low-grade fever and the drainage from his chest. the patient's sternal drainage continued to decrease, and on postoperative day seven it was decided that the sternal drainage had decreased sufficiently that the patient could safely be discharged to home. physical examination on discharge: condition on discharge revealed temperature maximum was 99.1 degrees fahrenheit, heart rate was 70 in sinus rhythm, his blood pressure was 101/62, respiratory rate was 16, and oxygen saturation was 98% on room air. neurologically, the patient was awake, alert and oriented times three. cranial nerves ii through xii were grossly intact. the patient had a nonfocal neurologic examination. heart was regular rate and rhythm without murmurs or rubs. the lungs were clear bilaterally without wheezes, rhonchi, or rales. the abdomen was soft, nontender, and nondistended. positive bowel sounds. the patient was tolerating a regular diet and having normal bowel movements. left vein harvest site was clean and dry. no erythema. steri-strips were intact. the sternal incision distal 5 cm of the incision had 1-cm or less surrounding erythema. there was scant serosanguineous drainage. the sternum was stable. the rest of the incision had steri-strips were intact, and there was no drainage. pertinent laboratory values: white blood cell count was 9.7, hematocrit was 32, and platelet count was 558. sodium was 133, potassium was 4.4, chloride was 95, bicarbonate was 28, blood urea nitrogen was 16, creatinine was 1, and blood glucose was 101. condition at discharge: condition on discharge was stable. discharge status: the patient was to be discharged to home. medications on discharge: 1. lasix 20 mg by mouth twice per day (times seven days). 2. potassium chloride 20 meq by mouth twice per day (times seven days). 3. colace 100 mg by mouth twice per day. 4. zantac 150 mg by mouth twice per day. 5. enteric-coated aspirin 325 mg by mouth every day. 6. percocet 5/325 mg one to two tablets by mouth q.4h. as needed. 7. imdur 60 mg by mouth once per day. 8. vitamin c 500 mg by mouth twice per day. 9. multivitamin one tablet by mouth once per day. 10. amiodarone 200 mg by mouth once per day. 11. lisinopril 5 mg by mouth once per day. 12. atenolol 100 mg by mouth once per day. 13. verapamil-sr 180 mg by mouth once per day. discharge diagnoses: 1. coronary artery disease. 2. status post coronary artery bypass graft. 3. postoperative atrial fibrillation. 4. postoperative sternal drainage. die instructions/followup: 1. the patient was to follow up with dr. in three to four weeks. 2. the patient was to return to two on , , for a wound check. 3. the patient was to follow up with his cardiologist (dr. in one to two weeks. 4. the patient was to be discharged with of hearts monitor with rhythm strip reports to be sent to dr. as directed. , m.d. dictated by: medquist36 procedure: extracorporeal circulation auxiliary to open heart surgery coronary arteriography using two catheters angiocardiography of left heart structures injection or infusion of platelet inhibitor left heart cardiac catheterization (aorto)coronary bypass of one coronary artery implant of pulsation balloon double internal mammary-coronary artery bypass nonoperative removal of heart assist system diagnoses: subendocardial infarction, initial episode of care coronary atherosclerosis of native coronary artery tobacco use disorder unspecified essential hypertension cardiac complications, not elsewhere classified gout, unspecified atrial fibrillation other specified complications of procedures not elsewhere classified other and unspecified alcohol dependence, unspecified
