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: allergies: patient recorded as having no known allergies to drugs attending: chief complaint: angina major surgical or invasive procedure: bental with 29mm aortic freestyle porcine valve, ascending and hemi-arch replacement(26mm gelweave), coronary artery bypass grafts x 2 (left internal mammary artery to left anterior descending, saphenous vein graft to diagonal) permanent pacemaker inserted history of present illness: this patient is a 67 year old white male who previously had critical aortic stenosis, ascending aortic aneurysm and coronary artery disease diagnosed afetr sustaining a myocardial infarction. he was catheterized at that time. he presents now with recurrent angina and ruled out for an infarct. he was tarsferred for surgery. past medical history: benign prostatic hypertrophy hypertrophy coronary artery disease ascending aortic aneurysm aortic stenosis hypertention noninsulin dependent diabetes mellitus adrenal mass social history: lives with wife. a daughter. tobacco use. there is no history of alcohol abuse. family history: no family history of early mi, arrhythmia, cardiomyopathies, or sudden cardiac death; otherwise non-contributory. physical exam: admission: vss afebrile. bp 114/73.rr-16 rasat-97% neuro:grossly intact lungs- clear cor- sr at 66 5/6 systolic nurmur rt sternal border. abd: benign ext: negative pertinent results: echo: pre-bypass: 1. the left atrium is moderately dilated. no atrial septal defect is seen by 2d or color doppler. 2. overall left ventricular systolic function is normal (lvef>55%). 3. right ventricular chamber size and free wall motion are normal. 4. the aortic root is mildly dilated at the sinus level. there are simple atheroma in the aortic root. the ascending aorta is moderately dilated. the aortic arch is mildly dilated. there are focal calcifications in the aortic arch. there are simple atheroma in the descending thoracic aorta. 5. the aortic valve is bicuspid. the aortic valve leaflets are severely thickened/deformed. significant aortic stenosis is present (not quantified due to lack of doppler data). mild (1+) aortic regurgitation is seen. post-bypass: for the post-bypass study, the patient was receiving vasoactive infusions including phenylephrine and is being av paced. 1. a well-seated stentless prosthetic valve in the aortic position with normal leaflet motion. no gradients were obtained, since no transgastric views were obtained. no aortic regurgitation is seen. 2. lv function is normal. 3. rv was mildly depressed. 4. an ascending aortic and partial arch graft noted 10:20am blood wbc-5.5 rbc-4.38* hgb-13.2* hct-38.0* mcv-87 mch-30.1 mchc-34.7 rdw-14.0 plt ct-270 07:30am blood wbc-8.1 rbc-3.41* hgb-10.2* hct-29.6* mcv-87 mch-29.9 mchc-34.4 rdw-15.7* plt ct-247 03:57am blood pt-14.4* inr(pt)-1.3* 10:20am blood pt-12.4 ptt-24.9 inr(pt)-1.0 07:10am blood glucose-166* urean-17 creat-1.1 na-138 k-3.6 cl-101 hco3-29 angap-12 10:20am blood glucose-285* urean-10 creat-1.0 na-137 k-4.1 cl-103 hco3-23 angap-15 brief hospital course: on mr. was taken to the operating room where a #29mm aortic root tissue valve/ bentall procedure, coronary artery bypass graft times two (left internal mammary artery grafted to the left anterior descending artery/saphenous vein grafted to the diagnal) and hemi-arch replacement(# 26mm gelweave) were performed. cross clamp time =194 minutes, cardiopulmonary bypass time= 239 minutes. circulatory arrest time= 24 minutes. please refer to dr operative report for further details. he weaned from bypass on propofol and neo-synephrine. following surgery he was transferred to the cvicu for invasive monitoring in stable condition. he required a therapeutic bronchoscopy to clear tenacious rul mucus which caused rul collapse. the lobe promptly re-expanded after this. pressors were weaned off over 36 hours and he weaned from sedation, awoke neurologically intact and was extubated. all lines and drains were removed in a timely fashion. beta blockers and diuresis were started and he was diuresed to his pre-op weight. on post-op day three ep was consulted for complete heart block. on a permanent pacemaker was placed. following this he was transferred to the step down unit for further telemetry and monitoring. ep interrogated the ppm. plan for follow up in device clinic 1 week following discharge. on post-operative day five he had failure to void and a foley was reinserted. a repeat void trial was not successful.he is to see his urologist dr. in 1 week. he continued to progress and on pod #8 was discharged to home with vna. all follow up appointments were advised. medications on admission: glipizide cr 20mg daily, valsartan 80mg daily, pravastatin 20mg daily, verapamil 240mg daily, percocet 5/325 mg tid prn, asa 325mg daily discharge disposition: home with service facility: home health and hospice discharge diagnosis: aortic stenosis ascending aortic aneurysm coronary artery disease noninsulin dependent diabetes mellitus hypertension hyperlipidemia benign prostatic hypertrophy discharge condition: good discharge instructions: shower daily, no baths or swimming no lotions, creams or powders to incisions no driving for 4 and off all narcotics no lifting more than 10 pounds for 10 report any redness of, or drainage from incisions report any fever greater than 100.5 report any weight gain greater than 2 pounds a day or 5 pounds a week take all medications as directed followup instructions: ep pacer device clinic wednesday @ 8:30 am - 7 dr.
