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 84-year-old white male was admitted to with acute shortness of breath and pulmonary edema on . he was intubated on admission secondary to hypoxia and was extubated on . his troponin was mildly elevated at 1.25, and he had normal creatine kinase enzymes. he was transferred to for cardiac catheterization. past medical history: significant for a history of prostate cancer 15 years ago, status post radical prostatectomy, history of bronchitis one and a half weeks prior to admission which was treated with zithromax, history of colon cancer 17 years prior to admission which was treated with a colon resection, history of skin cancer, and a history of neuropathy in his lower legs and feet. allergies: he has no known drug allergies. medications on admission: aspirin 81mg p.o. q.d., iron 325 mg p.o. q.d., and multivitamin one tablet p.o. q.d., stool softener as needed. social history: he lives alone. his wife died six months ago. he quit smoking 30 years ago - he had a 50-pack-year history. he drinks one glass of wine per day. family history: significant for coronary artery disease. review of systems: as above. physical examination on admission: he is an elderly white male in no apparent distress. vital signs were stable. he was afebrile. head, eyes, ears, nose, and throat examination revealed normocephalic and atraumatic. the extraocular movements were intact. the oropharynx was benign. the neck was supple. full range of motion. no lymphadenopathy or thyromegaly. he had bilateral radiating murmurs to the carotids. carotids were 2 plus and equal bilaterally and without bruits. the lungs were clear to auscultation and percussion. cardiovascular examination revealed a regular rate and rhythm. normal first heart sounds and second heart sounds with a 3/6 systolic ejection murmur. the abdomen was soft and nontender with positive bowel sounds. no masses or hepatosplenomegaly. the extremities were without clubbing, cyanosis, or edema. pulses were 1 plus and equal bilaterally throughout with the exception of the radial pulses which were 2 plus and equal bilaterally. neurologic examination was nonfocal. summary of hospital course: he underwent cardiac catheterization on admission which revealed a severe aortic stenosis with an aortic valve area of 0.7 cm2, and moderate mitral regurgitation, a 60 percent ostial left main coronary artery stenosis. the lad had mild luminal irregularities. the left circumflex had mild diffuse disease. the right coronary artery had a 15 percent ostial stenosis. his ejection fraction was 25 percent. dr. was consulted, and the patient also had a carotid duplex studies which showed no significant stenosis bilaterally. he had a dental consultation who cleared him for surgery. on , the patient underwent an avr with a 23-mm pericardial tissue valve and a coronary artery bypass grafting times one with a saphenous vein graft to the lad. the patient was transferred to the cardiac surgery recovery unit on levophed, epinephrine, milrinone, amiodarone, and propofol. he was extubated. shortly after extubation, he was in respiratory distress, and stridor, and tachypnea and was emergently re-intubated. on postoperative day one, he remained on amiodarone and milrinone. he was then extubated again over a bronchoscope on postoperative day one and did well. he remained on milrinone and neo-synephrine on postoperative day two. he had his chest tubes discontinued on postoperative day two. he remains on milrinone with a slow wean, and he had atrial fibrillation. on postoperative day three, he was started on captopril to wean off the milrinone. he also received some beta blocker and became bradycardic, and this was discontinued as well. on postoperative day five, he was transferred to the floor in stable condition. he continued to progress. discharge disposition: on postoperative day seven, he was discharged to rehabilitation in stable condition. medications on discharge: 1. lasix 20 mg p.o. b.i.d. (for seven days). 2. colace 100 mg p.o. b.i.d. 3. potassium 20 meq p.o. b.i.d. (for seven days). 4. aspirin 325 mg p.o. q.d. 5. tylenol as needed. 6. percocet one to two tablets by mouth q.4-6h. as needed. 7. captopril 25 mg p.o. t.i.d. laboratory data on discharge: white blood cell count was 10,200; his hematocrit was 40.8; and his platelets were 281,000. sodium was 137, potassium was 4, chloride was 103, bicarbonate was 24, blood urea nitrogen was 20, creatinine was 0.8, and blood glucose was 88. discharge diagnoses: 1. aortic stenosis. 2. coronary artery disease. discharge followup: he will be followed by dr. in one to two weeks and by dr. in four weeks. , dictated by: medquist36 d: 11:40:31 t: 12:07:32 job#: procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours extracorporeal circulation auxiliary to open heart surgery combined right and left heart cardiac catheterization coronary arteriography using two catheters angiocardiography of left heart structures insertion of endotracheal tube (aorto)coronary bypass of one coronary artery open and other replacement of aortic valve with tissue graft diagnoses: other iatrogenic hypotension coronary atherosclerosis of native coronary artery intermediate coronary syndrome personal history of tobacco use rheumatic heart failure (congestive) mitral valve insufficiency and aortic valve stenosis family history of ischemic heart disease acute bronchitis 

Answer: The patient is high likely exposed to
