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: the patient is an 83-year-old man transferred from an outside medical center. he has a past medical history significant for hypercholesterolemia, hypertension, and angina with a positive stress test in . patient refused cardiac catheterization at that time, and continued to experience chest pain about 10 episodes per week with radiation to the right arm and associated shortness of breath and palpitations. pain relieved by rest and sublingual nitroglycerin. patient was admitted to center on the and underwent cardiac catheterization at that time, which revealed three-vessel disease and an ef of 55 percent, two plus mitral regurgitation. patient denies any angina at rest. past medical history: hypertension. angina. hypercholesterolemia. appendectomy. right hand surgery. hemorrhoidectomy. allergies: he states no known drug allergies. medications on admission: 1. lipitor 20 every day. 2. atenolol 25 every day. 3. lisinopril 10 every day. 4. aspirin 81 every day. 5. nitro paste 1" every six hours. 6. heparin drip. social history: remote tobacco, quit in . no alcohol use. cardiac cath: ef of 55 percent. mitral valve: 2 plus mr. lad 99 percent stenosis, first diag 90 percent stenosis, om-1 95 percent stenosis. proximal rca 99 percent stenosis. pulmonary function tests at outside hospital showed a fev1 of 2.2. physical examination: vital signs: temperature 98.4, heart rate 60, blood pressure 152/66, respiratory rate 22, and o2 saturation of 96 percent on room air. general: in no acute distress. heent: pupils are equal, round, and reactive to light. mucous membranes moist. neck is supple. no carotid bruits. no jvd. cardiovascular: regular rate and rhythm, s1, s2. respiratory: clear to auscultation bilaterally. abdomen is soft, nontender, and nondistended. extremities: warm with no edema. pulses: carotids 2 plus without bruits. radial: 2 plus. femoral: 2 plus. popliteal: 2 plus. dorsalis pedis: dopplerable. hospital course: the following morning the patient was brought to the operating room, where he underwent coronary artery bypass grafting. please see the or report for full details. in summary, the patient had a cabg x4 with a lima to the lad, saphenous vein graft to om, saphenous vein graft to diag, and saphenous vein graft to the pda. his bypass time was 78 minutes with a cross-clamp time of 67 minutes. he was transferred from the operating room from the cardiothoracic intensive care unit in normal sinus rhythm at 84 beats per minute with a mean arterial pressure of 57 and cvp of 6. patient did well in the immediate postoperative period. his anesthesia was reversed. he was weaned from the ventilator and successfully extubated. he remained hemodynamically stable throughout the operative day. on postoperative day one, the patient continued to be hemodynamically stable. he was weaned from all iv cardioactive drips. his swan-ganz catheter was removed. he was begun on beta-blockers as well as diuretics and transferred to the floor for continued postoperative care and cardiac rehabilitation. following the transfer to the floor, he was noted to have rapid atrial fibrillation that responded well to lopressor and amiodarone following which he converted to a normal sinus rhythm. also on postoperative day two, the patient's chest tubes were discontinued. the remainder of the hospital course was uneventful. while on the floor, his activity level was gradually increased with the assistance of the nursing staff and the physical therapy staff. however, it was decided that the patient would require rehabilitation to get back to his baseline of activity. on postoperative day three, he was screened for rehabilitation. on postoperative day four, the patient was accepted at the rehabilitation center in and arrangements were made to discharge the patient on the following morning. at the time of this dictation, the patient's physical exam is as follows: vital signs: temperature 98.8, heart rate 74 sinus rhythm, blood pressure 100/70, respiratory rate 20. o2 saturation 96 percent on room air. weight preoperatively 78 kg, at discharge 78.4 kg. laboratory data: white count 12.6, hematocrit 31.4, platelets 158. sodium 134, potassium 4.5, chloride 97, co2 28, bun 25, creatinine 1.3, glucose 110. physical examination: neurologic: alert and oriented times three, moves all extremities, and follows commands. respiratory: clear to auscultation bilaterally. cardiovascular: regular rate and rhythm, s1, s2, no murmur. sternum is stable. incision with staples open to air clean and dry. abdomen is soft, nontender, nondistended with normoactive bowel sounds. extremities are warm and well perfused with no edema. right saphenous vein graft harvest site with staples open to air clean and dry. condition on discharge: good. disposition: he is to be discharged to rehabilitation center. final diagnoses: coronary artery disease status post coronary artery bypass grafting x4 with left internal mammary artery to the left anterior descending artery, saphenous vein graft to obtuse margin, saphenous vein graft to diagonal, saphenous vein graft to posterior descending artery. hypertension. hypercholesterolemia. appendectomy. right hand surgery. hemorrhoidectomy. follow-up instructions: the patient is to have followup with dr. in weeks after discharge from rehabilitation. follow up with dr. in weeks and follow up with dr. in four weeks. discharge medications: 1. amiodarone 400 mg twice a day x1 week, then 400 mg every day x1 week, then 200 mg every day. 2. trazodone 50 mg every night as needed. 3. percocet 5/325 1-2 tablets every four hours prn. 4. lasix 20 mg twice a day x2 weeks. 5. plavix 75 mg every day x3 months. 6. colace 100 mg twice a day. 7. aspirin 325 mg every day. 8. lopressor 25 mg twice a day. 9. lipitor 20 mg every day. , procedure: (aorto)coronary bypass of three coronary arteries single internal
