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: a 58-year-old male who had chest pain over a several week period with a subsequent exercise tolerance test that was positive who was admitted to where he underwent cardiac catheterization that showed a right-dominant circulation with 2-vessel coronary artery disease. the left main had no angiographic apparent disease. the lad had a 90% lesion after d1, and d1 had an 80% mid stenosis with the distal branch being totally occluded. the circumflex had minimal disease, and the rca was a dominant vessel with a proximal occlusion. his ef was calculated at 60%. there was no mitral regurgitation. lvedp at that time was 22. he was referred to cardiac surgery and readmitted on , at which time he underwent coronary artery bypass grafting. past medical history: significant for hypertension, hypercholesterolemia, and cad. past surgical history: significant for a cholecystectomy. medications prior to admission: include atenolol 25 mg daily, isosorbide 30 mg daily, lipitor 10 mg daily, aspirin 81 mg daily, vitamin e, and p.r.n. nitroglycerin. allergies: the patient states no known drug allergies. social history: positive tobacco use of 2 to 3 cigarettes per day. denies alcohol use. he is married and lives at home with his wife. family history: significant for cad. he has 1 brother had a mi in his 40s and another brother with cad who is alive in his 60s. laboratory data on admission: white count of 5.4, hematocrit of 38.6, and platelets of 217. sodium of 139, potassium of 4.5, chloride of 105, co2 of 18, bun of 18, creatinine of 0.8 , glucose of 134, with an inr of 1.0. physical examination on admission: temperature of 98, heart rate of 50 in sinus rhythm, blood pressure of 117/75, respiratory rate of 16, and o2 saturation of 96% on room air. in general, in no acute distress. neurologically, alert and oriented x 3. moves all extremities. follows commands. a nonfocal exam. the neck is soft with no jvd or bruits. the chest is clear to auscultation bilaterally. cardiovascular reveals a regular rate and rhythm s1 and s2 with no murmur. the abdomen is soft, nontender, and nondistended with normal active bowel sounds. the extremities are warm and well perfused with no edema. summary of hospital course: as stated previously, the patient was a direct admission to the operating room where he underwent coronary artery bypass grafting x 5. please the or report for further details. in summary, the patient had a cabg x 5 with a lima to the lad, a saphenous vein graft to the diagonal, with a jump graft to the distal diagonal, a saphenous vein graft to the pda, a saphenous vein graft to the rpl. bypass time on the first pump run was 100 minutes with a cross-clamp time of 37 minutes. on the second pump run his bypass time was 62 minutes with a cross-clamp time of 36 minutes. following initial wean from bypass, the patient had st changes necessitating an additional pump run, during which 2 additional grafts were placed. the patient tolerated the operation well and was transferred from the operating room to the cardiothoracic intensive care unit. at the time of transfer, the patient was a-paced at 80 beats per minute with a mean arterial pressure of 81 and a cvp of 1. at the time of transfer, the patient on neo-synephrine 1 mcg/kg/min and propofol at 20 mcg/kg/min. the patient did well in the immediate postoperative period. his anesthesia was reversed. he was weaned the ventilator and successfully extubated. on the evening of the surgery, the patient remained hemodynamically stable requiring only neo-synephrine to maintain an adequate blood pressure. during that period he was given 2 units of packed red blood cells. on the morning of postoperative day 1, the patient continued to be hemodynamically stable. his swan-ganz catheter was removed. he was slowly weaned from his neo-synephrine infusion, and he was kept in the intensive care unit for hemodynamic monitoring. on postoperative day 2, the patient continued to do well. he continued to slowly wean off his neo- synephrine infusion. his chest tubes were removed. he was started on diuretics, and again he was maintained in the intensive care unit for close hemodynamic monitoring. by postoperative day 3, the patient had been completely weaned off of his neo-synephrine and continued to be aggressively diuresed and was transferred from the cardiothoracic intensive care unit to two for continued postoperative care and cardiac rehabilitation. once on the floor, the patient had an uneventful operative course. he was noted to have brief episodes of atrial fibrillation with a ventricular response rate up to 140. he was treated with beta blockade each time and converted to a normal sinus rhythm. after 3 episodes he was begun on amiodarone orally as well as anticoagulated with coumadin. over the next several days the patient's activity level was increased with the assistance of the nursing staff and physical therapy. on postoperative day 6, it was decided that the patient was stable and ready to be discharged to home with visiting nurses. the patient's physical exam at the time of discharge revealed a temperature of 98.5, heart rate of 68 in sinus rhythm, blood pressure of 124/72, respiratory rate of 20, and o2 saturation of 96% on room air. weight preoperatively was 81 kilograms. at discharge was 84 kilograms. neurologically, alert and oriented x 3. moved all extremities. followed commands. a nonfocal exam. pulmonary revealed clear to auscultation bilaterally. cardiac revealed a regular rate and rhythm. s1 and s2. the sternum was stable. incision with steri-strips open to air, clean and dry without drainage or erythema. the abdomen was soft, nontender, and nondistended with normal active bowel sounds. the extremities were warm and well perfused with no edema. left open saphenous vein graft incision with steri-strips, open to air, clean and dry. laboratory data on the day of discharge revealed a sodium of 136, potassium of 4.1, chloride of 105, co2 of 27, bun of 20, creatinine of 0.9, glucose of 115. white count of 7.5, hematocrit of 26.2, and platelets of 221. pt of 13 with an inr of 1.1. condition on discharge: good. discharge followup: he is to have followup in the clinic in 2 weeks, followup with dr. in 3 to 4 weeks, follow up with dr. in 3 to 4 weeks, and
