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 67 year old white male has a known left carotid stenosis and was initially admitted to hospital on , with extreme viral symptoms including fatigue, malaise and now lower extremity edema. he had been feeling well prior to the flu episode and did not have symptoms of congestive heart failure. he had a positive troponin of 3. changes on his ekg. his echocardiogram revealed an ejection fraction of 15% with generalized akinesis, hypokinesis of the septum and one to two plus mitral regurgitation. he presented to the outside hospital with paroxysmal nocturnal dyspnea and orthopnea and was diuresed and started on an ace inhibitor. he was transferred to for a cardiac catheterization. past medical history: 1. positive stress test in . 2. leg fracture in the past. 3. left carotid stenosis of 50 to 80%. 4. he has had some visual field loss since childhood. medications: he was on no medications at home. allergies: he has no known drug allergies. social history: he has a 30 pack year smoking history and quit two weeks prior to admission. he drinks alcohol rarely. he is married and lives with his wife. works in real estate. review of systems: unremarkable. physical examination: on physical examination, he is a thin white male in no apparent distress. vital signs were stable; he was afebrile. heent examination is normocephalic, atraumatic. extraocular movements intact. oropharynx had poor dentition. neck was supple with full range of motion; no lymphadenopathy or thyromegaly. carotids were two plus and equal bilaterally without bruits. lungs were had bibasilar crackles. cardiovascular examination had a regular rate and rhythm with a iii/vi holosystolic murmur. abdomen was soft, nontender, with positive bowel sounds, no masses or hepatosplenomegaly. extremities were without cyanosis, clubbing or edema. pulses were two plus and equal bilaterally except for his dorsalis pedis which were doppler-able. neurological examination was non-focal. hospital course: the patient was catheterized and had a tubular 80% stenosis of the left main coronary artery, a proximal 90% stenosis of the left anterior descending. the left circumflex was non-dominant and was occluded ostially. the right coronary artery was dominant and occluded ostially. the patient did become hypotensive and had a cardiac index of 1.4 in the catheterization laboratory. he had an intra-aortic balloon placed and he was started on dobutamine. dr. was consulted. the patient also had a carotid ultrasound which showed a left carotid stenosis, 50 to 80%. he remained in the coronary care unit. an echocardiogram revealed his ejection fraction was 15% and on he underwent a coronary artery bypass graft times three with left internal mammary artery to the left anterior descending, reversed saphenous vein graft to the patent ductus arteriosus and obtuse marginal, and a mitral valve replacement with a #28 millimeter annuloplasty band. the crossclamp time was 86 minutes; total bypass time 134 minutes. he was transferred to the csru on epinephrine, levophed, milrinone, dobutamine and propofol. he was stable on his postoperative night. his levophed was quickly weaned. we then added nitroglycerin for his blood pressure. he was started on amiodarone for ventricular ectopy. he was extubated on postoperative day number one. he remained on epinephrine and milrinone and his balloon pump was slowly weaned and was discontinued on postoperative day number four. he then remained on epinephrine, milrinone and nitroglycerin and was also followed by the heart failure team. he was gently diuresed as well. he eventually weaned off his epinephrine and then his milrinone as he was started on captopril. he continued to improve and on postoperative day number 13, he was transferred to the floor in stable condition. he continued to have a stable postoperative course. his left lower extremity had a saphenectomy site which did have a little swelling but it was not infected, and this improved over a couple of days. he was eventually switched over to lisinopril and started on some toprol xl at a low dose. on postoperative day number 13, he was discharged to home in stable condition. laboratory: on discharge, white blood cell count 10,700, hematocrit 37.7, platelets 805. sodium 130, potassium 5.0, chloride 97, carbon dioxide 22, bun 15, creatinine 1.1, blood sugar 84. discharge medications: 1. percocet one to two p.o. q. four to six hours p.r.n. pain. 2. ecotrin 325 mg p.o. q. day. 3. amiodarone 400 mg p.o. twice a day for one week, then decrease to 400 mg p.o. q. day for one week, and then 200 mg p.o. q. day. 4. lisinopril 10 mg p.o. q. day. 5. toprol xl 12.5 mg p.o. q. day. 6. clindamycin 600 mg p.o. q. day times one week. discharge instructions: 1. he will follow-up with dr. on , at 09:00 a.m. 2. he needs to make an appointment with dr. in one to two weeks. 3. he will see dr. on wednesday, , to check his leg and then he will follow-up with him in six weeks. 4. he also needs to be seen by a dentist for evaluation of possible dental extractions. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery combined right and left heart cardiac catheterization (aorto)coronary bypass of two coronary arteries implant of pulsation balloon annuloplasty monitoring of cardiac output by other technique transfusion of packed cells transfusion of other serum transfusion of platelets diagnoses: subendocardial infarction, initial episode of care coronary atherosclerosis of native coronary artery mitral valve disorders congestive heart failure, unspecified cardiac complications, not elsewhere classified other chronic pulmonary heart diseases systolic heart failure, unspecified occlusion and stenosis of carotid artery without mention of cerebral infarction cardiogenic shock
