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 an 84-year-old male who is preoperative for a right knee replacement who underwent a preoperative ett. after three minutes, he had to stop secondary to fatigue and he had myocardial ischemia with decreased kinesis in the anterior apical region. his ejection fraction was 40% and he had a right bundle branch block. he denies chest pain, diaphoresis, or shortness of breath. he underwent cardiac catheterization at on which revealed no mitral regurgitation, ejection fraction of 45%, anteroapical hypokinesis, lmca normal, left anterior descending artery 70% proximal, 90% mid, left circumflex 70%, om 90%, right coronary artery 90%, ........... 90% pcv. the patient is to undergo cabg this am. past medical history: 1. status post open polypectomy 14 years ago. 2. hypertension. 3. osteoarthritis. 4. mild congestive obstructive pulmonary disease. 5. left total knee replacement 12 years ago. home medications: 1. aspirin 81 mg po q

percocet two tablets q6 prn. 9. oxycontin 20 mg po bid. allergies: no known allergies, no allergy to shellfish, no allergy to dye. social history: no cigarettes. two beers a day. the patient lives with daughter and son. family history: unremarkable. physical examination: in general, patient is in no acute distress. he is afebrile, heart rate 50, blood pressure 160/70. heent is normocephalic, atraumatic. pupils are equal, round, and reactive to light. extraocular movements are intact. nasopharynx is benign. neck is supple, full range of motion, no lymphadenopathy. no thyromegaly. carotids are 2+ bilaterally without bruits. lungs are clear to auscultation bilaterally. cardiac: regular, rate, and rhythm, no murmurs. abdomen has positive bowel sounds, soft, nontender, nondistended without masses, no hepatosplenomegaly. carotids are 2+ bilaterally without bruit. extremities without clubbing, cyanosis, or edema. pulses 2+ bilaterally throughout. neurologic is nonfocal. hospital course: the patient was taken to the operating room on for coronary artery bypass x4, lima to left anterior descending artery, saphenous vein graft to diagonals, saphenous vein graft to om, saphenous vein graft to pda. patient appeared to tolerate the procedure and was transferred to the cardiothoracic surgery intensive care unit postoperatively. during the first 24 hours postoperatively, the patient experienced seven beat ventricular tachycardia. was given magnesium. patient was started on beta blocker as well as lasix. patient arrived to the intensive care unit as well with chest tube and cardiac pacing wires in place. patient also in the intensive care unit experienced right atrial fibrillation at times. the patient received vancomycin x4 perioperatively. also started on captopril. while in the intensive care unit, the patient experienced an increase in creatinine and diuretics was temporarily stopped. once the patient was stable, he was transferred to the regular cardiothoracic floor. his chest tubes and cardiac pacing wires were removed at the appropriate time. while on the floor, it was noted that the patient had significant blood pressure control issues. the patient was restarted on his oxycontin in an attempt to improve his blood pressure control. he was also started on captopril and slowly advanced. he was also started on amlodipine and slowly advanced finally without success, but the patient had the cardiac service consult to aid in his blood pressure control. while in-house, the patient was seen by physical therapy on a number of occasions. by the end of his stay, physical therapy agreed that the patient would be able to go home after discharge. also while in-house, the patient was noted to require an insulin-sliding scale. the patient was not previously diabetic, so the diabetes center was consulted, who indicated the patient would be better evaluated and not in the acute setting. i also indicated that it would be appropriate to get a nutrition consult for dietary education. this was done. cardiac service that patient be switched from captopril to lisinopril which was done. it is now , and it is anticipated that the patient will be discharged home tomorrow on . condition on discharge: he will be discharged in good condition. follow-up instructions: he is to followup with dr. in four weeks. he is to followup with his primary care
