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 55-year-old gentleman with known coronary disease, status post multiple pci. the patient most recently was hospitalized in after a positive stress test and catheterization which showed three vessel disease. at that time, it was thought the patient would be better served by coronary artery bypass grafting. the patient reports a history of worsening exertional angina and now with occasional rest pain, all relieved by sublingual nitroglycerin. past medical history: coronary artery disease. status post myocardial infarction . peripheral vascular disease. hypertension. hypercholesterolemia. status post right cea in . status post left cea in . status post aorto-bifemoral bypass graft in . status post thrombectomy of the right brachial artery in . status post multiple cardiac catheterizations and pci's. preoperative medications: 1. lipitor 40 mg p.o. once a day. 2. plavix 75 mg p.o. once a day. 3. imdur 120 mg p.o. once a day. 4. toprol xl 200 mg p.o. once a day. 5. protonix 40 mg p.o. once a day. 6. colace. 7. lisinopril 5 mg p.o. once a day. 8. aspirin 325 mg p.o. once a day. allergies: no known drug allergies. hospital course: the patient was admitted to on and taken to the operating room for a coronary artery bypass graft times three, lima to lad, saphenous vein graft to om and saphenous vein graft to ramus with dr. . please see operative note for further details. the patient was transferred to the intensive care unit in stable condition on neo-synephrine, amiodarone and propofol. the amiodarone was started in the operating room due to the patient developing ventricular tachycardia prior to cardiopulmonary bypass. please see operative note for full details. upon arrival to the intensive care unit, the patient was noted to have several hours of significant chest tube drainage. at the time of his admission to the intensive care unit, the patient was noted to be hypothermic and have mild coagulopathy. once the coagulopathy was resolved, chest tube output markedly decreased and at that time, the patient was noted to have acute elevation in his filling pressures with a resultant significant decrease in his systemic blood pressure. it was felt the patient was noted to be in acute tamponade and the patient required to have his chest incision opened and his sternum explored at the bedside. upon opening the chest and removing a large amount of clot, the patient's hemodynamics improved. the patient was taken back to the operating room where the incision was irrigated and all bleeding was controlled and the patient was transported back to the intensive care unit in stable condition. upon returning to the intensive care unit, the patient had been placed on low dose milrinone and levophed infusion. in the operating room, the patient's ejection fraction was noted to be 50 percent. the patient was weaned and extubated from mechanical ventilation on postoperative day no. 1 . the patient required ________ for optimal sedation to achieve extubation. the patient's hemodynamics were good. the milrinone was discontinued with good hemodynamics. as well, on postoperative day no. 1, the patient was noted to have several episodes of atrial fibrillation which continued into the early morning of postoperative day no. 2. the patient received boluses of amiodarone and low dose lopressor. the patient's chest tubes remained in due to an air leak. on postoperative day no. 2, the patient's pulmonary artery catheter was discontinued. the patient was started on lopressor and the patient was transferred from the intensive care unit to the regular part of the hospital. upon arrival on the floor, the patient was noted to be in atrial fibrillation, rate controlled. the patient was also having several episodes of 4 to 5 beats of nonsustained ventricular tachycardia. electrophysiology consultation was obtained. it was recommended that the patient get an echocardiogram to assess right ventricular and left ventricular function. as the patient had normal left ventricular function, the patient would just be treated with amiodarone and beta blockers. the patient had an echocardiogram on postoperative day no. 5 which showed an ejection fraction of 45 to 50 percent. no pericardial effusion, 2 plus mitral regurgitation. the morning of postoperative day no. 6, the patient converted to sinus rhythm although intermittently had brief episodes again of atrial fibrillation. the patient was started on heparin infusion as well as coumadin for anti-coagulation. the patient's chest tube was removed. post removal, chest x-ray showed a small left apical pneumothorax with complete resolution by postoperative day no. 6. by postoperative day no. 6, the patient had completed a level 5 of physical therapy and was able to ambulate 500 feet and climb one flight of stairs. electrophysiology service recommended the patient be discharged on continued amiodarone and coumadin for anticoagulation as well as be discharged home with of hearts monitor. on the evening of postoperative day no. 5, the patient was noted to have a fair amount of serosanguinous drainage from his sternal incision. the patient was started on keflex as well. on postoperative day no. 6, the patient was noted to have a thrombophlebitis of the left forearm from an old intravenous site. this progressively got better over the next several days. the sternal incision never had any erythema and the patient was never febrile. the drainage decreased over the next several days and stopped by postoperative day no. 7. the patient continued on his keflex and by postoperative day no. 7 he was cleared for discharge to home. condition on discharge: tmax 98.7 degrees, pulse 74 in sinus rhythm, blood pressure 117/52, respiratory rate 20, room air oxygen saturation 94 percent. neurologically, the patient is awake, alert, oriented times three, nonfocal. heart is regular rate and rhythm without rub or murmur. breath sounds are clear bilaterally. sternal incision is clean and dry. there is no erythema. there is no drainage. sternum is stable. abdomen soft and nontender, nondistended. the patient is tolerating a regular diet and having normal bowel movements. lower extremities are warm and well perfused with trace to 1 plus pitting edema. the right lower extremity vein harvest site clean and dry without erythema or drainage. laboratory data: white blood cell count 8.2, hematocrit 28.7, platelet count 390. sodium 138, potassium 4.5, chloride 103, bicarbonate 22, bun 13, creatinine 1.0, glucose 103. the patient's pt is 16.4, inr of 1.8. discharge medications: 1. lopressor 25 mg p.o. twice a day. 2. lasix 20 mg p.o. once a day times 7 days. 3. potassium chloride 20 meq

12. coumadin. the patient is to take 2 mg on , and . the patient is to have pt and inr checked on with the results called to dr. office and further coumadin dosing and inr checks are to be per dr. . the patient is to be discharged to home in stable condition. the patient is to follow-up with dr. office by phone on , , and in the office on at 2:30 p.m. he is to follow-up with dr. in one to two weeks, and he is to follow-up with dr. in five to six weeks. discharge diagnoses: coronary artery disease. status post coronary artery bypass graft times three. postoperative atrial fibrillation.
