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 is a 63-year-old male with a history of hypercholesterolemia, hypertension, tobacco use, sleep apnea, and known as/ai who had cardiac cath ten years prior and had mild to moderate coronary artery disease per the patient's recollection. thursday prior to admission, he was walking outside to clear snow and had a questionable syncopal episode. he found himself lying on his back on the floor. the fall was not witnessed. he believes he had loss of consciousness for a few seconds. as a result of the fall, he sustained a laceration to the back of the head. he refused to go to the hospital at that time. he denied slurred speech or visual changes, weakness or confusion following the event. the next morning, the patient awoke with severe dyspnea and diaphoresis. he presented to the emergency department where he underwent vq scan to rule out pe which resulted in low probability. the patient was treated with prednisone and inhalers for presumed asthma and sent home. he came for follow-up to his doctor's the day prior to admission where the patient became acutely short of breath with diaphoresis with midsternal and nonradiating chest pain and nausea. he presented to the emergency department where he was treated with nitroglycerin sublingual times three, lasix 40 mg iv, and oxygen. he diuresed 1200 cc with improvement in his symptoms. he was ruled out for myocardial infarction. the patient had a 14 lb weight gain over the previous month with no change in diet. he denied lower extremity edema. he has chest tightness in the past with significant exertion. he denied any prior myocardial infarction. ett from showed no chest pain. this was stopped due to fatigue. he had mild to moderate shortness of breath. he had nonspecific st changes. echocardiogram done that same day showed no wall motion abnormality, ejection fraction of 60%, borderline left ventricular hypertrophy, + mitral regurgitation, and + aortic insufficiency, moderate aortic stenosis. the patient was transferred for cardiac catheterization to rule out coronary artery disease and evaluated mitral valve and aortic valve. past medical history: aortic stenosis. hypertension. hypercholesterolemia. passive alcohol use. sleep apnea. chronic obstructive pulmonary disease. obesity. past surgical history: tonsillectomy. uvuloplasty for sleep apnea six weeks prior to admission. allergies: no known drug allergies. medications: lasix 20 mg p.o. q.d., started at an outside hospital, aspirin 162 mg p.o. q.d., captopril 12.5 mg p.o. t.i.d., also started at the outside hospital, lipitor 40 mg p.o. q.d., zoloft 25 mg p.o. q.d. laboratory data: hematocrit 35%, hemoglobin 9.6, platelet count 334, white count 9.4; electrolytes were within normal limits with a creatinine of 1.5; inr 0.9; ck peak was 162, troponin negative. physical examination: deferred. hospital course: the patient was brought directly to the lab. the patient was found to have aortic stenosis, mild 1+ aortic insufficiency, elevated wedge pressure, pulmonary artery hypertension, likely multifactorial, mitral regurgitation, ejection fraction of 60% with normal end diastolic volume, trace mitral regurgitation, right dominant system, large om and atrial branch at av groove, a lesion in a circumflex branch and a small right coronary artery with total mid occlusion. the patient underwent aortic valve replacement with a 19 mm mosaic porcine valve and coronary artery bypass grafting times two with saphenous vein graft to om and saphenous vein graft to right coronary artery. the patient tolerated the procedure without complications. he was extubated on postoperative day #1. he continued to do well. the patient had an uneventful hospital course. by postoperative day #4, the patient was able to ambulate well, was tolerating a regular diet, and had good p.o. pain control. he was felt to be ready for discharge to home with follow-up with dr. in four weeks and with his primary care physician . in weeks, and with his cardiologist in weeks. discharge medications: lopressor 50 mg b.i.d., lasix 20 mg b.i.d. x 7, atorvastatin 40 mg q.d., captopril 12.5 mg t.i.d., percocet tab p.o. q.4-6 hours p.r.n., potassium chloride 20 meq b.i.d. x 7, ibuprofen 400 mg q.6 hours p.r.n., tylenol 650 mg q.4 hours p.r.n., aspirin 325 mg q.d., zantac 150 mg b.i.d., colace 100 mg b.i.d. condition on discharge: good. discharge status: to home. discharge diagnosis: status post aortic valve replacement, coronary artery bypass grafting times two. , m.d. dictated by: medquist36 d: 11:35 t: 11:50 job#: procedure: extracorporeal circulation auxiliary to open heart surgery combined right and left heart cardiac catheterization coronary arteriography using two catheters (aorto)coronary bypass of two coronary arteries angiocardiography of left heart structures open and other replacement of aortic valve with tissue graft aortography diagnoses: coronary atherosclerosis of native coronary artery pure hypercholesterolemia congestive heart failure, unspecified unspecified essential hypertension chronic airway obstruction, not elsewhere classified aortic valve disorders personal history of tobacco use unspecified sleep apnea 

Answer: The patient is high likely exposed to
