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: chest pain major surgical or invasive procedure: s/p ascending aorta and hemi-arch replacement history of present illness: 57 y/o male with h/o htn who presented to osh with chest pain and approx. 1 week of dizziness. patient had a ct scan which revealed a type a aortic dissection. emergently transported to for surgical repair. past medical history: hypertension diabetes mellitus social history: tobacco x 20yrs (1 ppd), quit 20 yrs ago denies etoh, drugs family history: sister had aortic aneurysm at 58 physical exam: vs: 98.3 62 lbp 148/79 rbp 145/79 18 100% 5l general: awake and alert lungs: ctab cor: rrr, +s1s2, -bruits abd: soft nt/nd pulses: 2+ throughout pertinent results: chest ct : the original impression was typed incorrectly in the draft report. this is a type a aortic dissection involving the ascending aorta, not the descending. echo : pre-bypass: the ascending aorta is moderately dilated. the descending thoracic aorta is mildly dilated. there are simple atheroma in the descending thoracic aorta. a mobile density is seen in the ascending aorta consistent with an intimal flap/aortic dissection. there is flow in the false lumen. there are three aortic valve leaflets. the aortic valve leaflets are mildly thickened. trace aortic regurgitation is seen. mild (1+) mitral regurgitation is seen. there is a moderate sized pericardial effusion. dissection flap visualized in the ascending aorta originationg from the sinotubular junction, to the ascending aorta. no dissection flap visualized in the descending thoracic aorta posr cpb: preserved biventricular systolic function. tube graft visualized in the ascending aortic position, without evidence of compression/abnormal flow pattern on the cfd. cxr : 02:50am blood wbc-9.2 rbc-4.08* hgb-13.6* hct-35.9* mcv-88 mch-33.2* mchc-37.8* rdw-14.6 plt ct-118* 05:33am blood wbc-9.1 rbc-3.76*

emergent ct scan which confirmed a type a aortic dissection. he was emergently brought to the operating room where he underwent an ascending aorta and hemi-arch replacement. please see operative note for surgical details. mr. tolerated the procedure well and was transferred to the csru in stable condition. patient remained sedated/paralyzed until post-operative day four d/t being unable to wean from ventilator because of poor respiration and agitation. he was finally weaned from sedation, awoke neurologically intact and weaned from mechanical ventilation and extubated. chest tubes were removed on post-op day two. aspirin and diuretics were initiated on post-op day one. he was initially aggressively diuresed w/ pulmonary toilet followed by gentle diuresing during his entire post-operative period towards his pre-op weight. lopressor was initiated and eventually captopril and norvasc were added. all three were adjusted for optimal blood pressure control. his epicardial pacing wires and foley catheter were removed on post-op day six. he was transfused 1 unit of prbc's on post-op day six with adequate response in his hct. as mentioned earlier he had episodes of agitation and several episodes of confusion which were believed to be related to post-cardiopulmonary bypass. he eventually was improving and with stable vital signs and was transferred to the cardiac surgery step-down unit on post-op day seven. on post-op day eight he had drainage from his right groin with mild erythema and small seperation. very mild increase in his wbc without a fever. vancomycin was started alond with dressing changes tid. physical therapy began working with patient for post-op strength and mobilty. his groin wound drainage decreased but had persistent erythema around the margins. there was no frank purulence. on pod 11 mr. was afebrile, his wbc count was normal, he was 3kg below his preop weight with good exercise tolerance, no sob, or chest pain. his blood pressure was stable. his sternotomy was clean, dry, and intact without evidence of infection. he was discharged home on pod 11 in good condition, cardiac diet, sternal precautions, and instructed to follow up with his pcp/cardiologist in weeks. he was instructed to conduct twice daily wet to dry dressing changes to his groin, paint the wound margins with betadine and take cipro 500mg po bid x 7
