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 69 year old russian speaking male has a history of shortness of breath at rest and chest pain at rest and with exertion for the past seven years. it has increased over the past year and he had a positive stress test and a positive murmur and he was referred for cardiac catheterization. an echocardiogram revealed aortic stenosis with an aortic valve area of 1.2 centimeters squared, a peak gradient of 44, a mean gradient of 77 and left ventricular hypertrophy. his cardiac catheterization was done at on , which revealed coronary artery disease with 75 to 80% proximal stenosis of the right coronary artery which was an in-stent restenosis; the circumflex had an 80% mid stenosis, left anterior descending had a 70% proximal stenosis and his ejection fraction was 67% with posterior basilar hypokinesis, mild mitral regurgitation, and aortic stenosis. he is now admitted for aortic valve replacement and coronary artery bypass graft. past medical history: 1. history of aortic stenosis. 2. status post myocardial infarction. 3. status post cerebrovascular accident in 10/. 4. history of epistaxis. 5. history of hypertension. 6. history of remote renal calculi. 7. history of hypercholesterolemia. 8. history of obesity. 9. status post left eye laser surgery. 10. status post renal artery stent. 11. history of benign prostatic hypertrophy. 12. status post right coronary artery stent in . 13. status post bilateral iliac arterial stent. 14. history of peripheral vascular disease. 15, history of bilateral claudication. medications on admission: 1. altace 10 mg p.o. q. day. 2. toprol 100 mg p.o. q. day. 3. lipitor 40 mg p.o. q. day. 4. doxazosin 16 mg p.o. q. day. 5. proscar 5 mg p.o. q. day. 6. hydrochlorothiazide 25 mg p.o. q. day. 7. aspirin 162 mg p.o. q. day. 8. keflex 500 mg p.o. four times a day which he finished the day prior to admission. 9. cosopt eye drops, one drop o.u. twice a day. allergies: he has no known drug allergies. he had dental clearance prior to admission. family history: significant for severe coronary artery disease. social history: he quit smoking in ; drinks alcohol rarely and lives with his wife. review of systems: significant for chronic renal insufficiency, benign prostatic hypertrophy, severe claudication and cerebrovascular accident. physical examination: on physical examination, he is a well developed elderly white male in no apparent distress. vital signs are stable; he is afebrile. heent examination is normocephalic, atraumatic. extraocular movements intact. oropharynx is benign. neck was supple with full range of motion; no lymphadenopathy or thyromegaly. carotids two plus and equal bilaterally with radiating murmurs. lungs were clear to auscultation and percussion. cardiovascular examination is regular rate and rhythm with normal s1 and s2 with a ii/vi systolic ejection murmur. abdomen was obese, soft, nontender, with positive bowel sounds. no masses or hepatosplenomegaly. extremities without cyanosis, clubbing or edema. pulses: his femorals were two plus and equal bilaterally. dorsalis pedis and posterior tibial were one plus and equal bilaterally. radial were two plus and equal bilaterally. neurological examination was non-focal. hospital course: on , he underwent an aortic valve replacement with a #25 magna pericardial valve and a coronary artery bypass graft times three with left internal mammary artery to the left anterior descending, reverse saphenous vein graft to the ramus and the obtuse marginal; cross clamp time was 155 minutes; total bypass time was 183 minutes. he was transferred to the csru on neo-synephrine and propofol. he remained intubated overnight. he was extubated on postoperative day number two. he required aggressive diuresis and respiratory therapy. he had a swan and chest tube discontinued on postoperative day number two. he had nonsustained ventricular tachycardia on postoperative day number two. he also had atrial fibrillation intermittently and was started on amiodarone. electrophysiology service followed him and felt that we could just watch this and after he was started on amiodarone he did not have any further ectopy. he remained in the unit for aggressive diuresis and respiratory therapy and on postoperative day five, he developed an ileus and had diarrhea as well. he was started on flagyl and his clostridium difficile was negative throughout and it was discontinued. his abdomen remained distended. he was followed by general surgery who felt he could just have conservative management and eventually he was able to tolerate a diet well. he was transferred to the floor on postoperative day number seven. he continued to progress with physical therapy and on postoperative day number ten he was discharged to home in stable condition. his labs on discharge were hematocrit of 29.9, white blood cell count of 8,900, platelets 245, sodium 142, potassium 4.0, chloride 101, carbon dioxide 30, bun 23, creatinine 1.4 with a blood sugar of 112. discharge medications: 1. amiodarone 400 mg p.o. twice a day times one week, then reduce to 400 mg p.o. q. day times one week and then decrease to 200 mg p.o. q. day. 2. colace 100 mg p.o. twice a day. 3. cosopt one drop o.u. twice a day. 4. aspirin 325 mg p.o. q. day. 5. cardura 2 mg p.o. q. h.s. 6. percocet one to two p.o. q. four to six hours p.r.n. pain. 6. proscar t mg p.o. q. day. 7. lopressor 25 mg p.o. twice a day. 8. lipitor 40 mg p.o. q. day. 9. ramipril 5 mg p.o. q. day. 10. lasix 40 mg p.o. q. day times seven days. 11. kayciel 20 meq p.o. twice a day times seven days. discharge instructions: 1. he will be followed by dr. in one to two weeks. 2. he will be followed by dr. in four weeks. discharge diagnoses: 1. aortic stenosis. 2. coronary artery disease. 3. atrial fibrillation. 4. hypertension. 5. hypercholesterolemia. 6. ileus. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery (aorto)coronary bypass of two coronary arteries non-invasive mechanical ventilation open and other replacement of aortic valve with tissue graft diagnoses: coronary atherosclerosis of native coronary artery unspecified essential hypertension cardiac complications, not elsewhere classified atrial fibrillation aortic valve disorders paroxysmal ventricular tachycardia other and unspecified angina pectoris paralytic ileus
