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: ascending aortic arch repair with graft (type a dissection) history of present illness: 43 yo with h/o hypercholesterolemia and htn. the pt presented to the ed with chest pressure which began during vigorous bicycle riding two hours prior. he has no previous history of such discomfort. on arrival, he denies dizziness, lightheadedness, sob, loc. the pt received heparin and nitro in the ed as part of cardiac/ acs workup. cta revealed ascending aortic dissection. he was admitted for further management. past medical history: htn, hypercholesterolemia social history: lives alone. works as an attorney. reports occasional alcohol use and no tobacco use. family history: father has hypertension. physical exam: general: nad neck: no bruits lungs: ctab heart: rrr, no murmur abd: soft, nt, nd, nabs ext: warm, no edema neuro: grossly intact pulses: femoral r:2+ l:2+ dp r:2+ l:2+ pt r:2+ l:2+ radial r:2+ l:2+ pertinent results: intra-operative tee: conclusions prebypass 1.no atrial septal defect is seen by 2d or color doppler. 2. regional left ventricular wall motion is normal. 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. the ascending aorta is markedly dilated. a mobile density is seen in the ascending aorta consistent with an intimal flap/aortic dissection that extends from the left subclavian take off to the sinotubular junction. 5. the aortic valve leaflets (3) are mildly thickened but aortic stenosis is not present. mild (1+) aortic regurgitation is seen. 6.the mitral valve appears structurally normal with trivial mitral regurgitation. 7.there is no pericardial effusion. 8.dr. was notified in person of the results on at 1530. post bypass 1. patient is in sinus rhythm. 2. biventricular systolic function unchanged. 3. distal arch has a portion of the dissection flap with the entry site. dr aware. 4. possible extension of the dissection into the left subclavian. dr aware of this finding as well. 5. mild aortic insufficiency persists. brief hospital course: pt was admitted to on and brought emergently to the operating room where he underwent repair type a aortic dissection, resuspension aortic valve, placement 28 mm dacron gel weave graft. overall the patient tolerated the procedure well and postoperatively was transferred to the cvicu for further observation and recovery. pod 1- the pt remained intubated. he was found to be agitated and right pupil was dilated. neurology consult was obtained. ct revealed no evidence of acute ischemic changes. pupil would subsequently return to normal size. the pt was extubated by pod 2. chest tubes and pacing wires were discontinued without complication. the patient was transferred to the floor on pod 3. physical exam revealed new onset bruit in the right carotid. ultrasound was ordered- and suspicious for dissection into this area. further testing was ordered, including a perfusion scan, as well as neurosurgery/interventional neuroradiology consult. perfusion scan was normal and he was ready for discharge home. medications on admission: avapro 300' discharge medications: 1. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). disp:*60 capsule(s)* refills:*0* 2. ranitidine hcl 150 mg tablet sig: one (1) tablet po bid (2 times a day). disp:*60 tablet(s)* refills:*0* 3. aspirin 81 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po daily (daily). disp:*30 tablet, delayed release (e.c.)(s)* refills:*0* 4. oxycodone-acetaminophen 5-325 mg tablet sig: 1-2 tablets po every 4-6 hours as needed for pain. disp:*50 tablet(s)* refills:*0* 5. ferrous sulfate 325 mg (65 mg iron) tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*0* 6. ascorbic acid 500 mg tablet sig: one (1) tablet po bid (2 times a day). disp:*60 tablet(s)* refills:*0* 7. metoprolol tartrate 25 mg tablet sig: one (1) tablet po bid (2 times a day). disp:*60 tablet(s)* refills:*0* 8. lasix 40 mg tablet sig: one (1) tablet po once a day for 10 days. disp:*10 tablet(s)* refills:*0* 9. potassium chloride 20 meq tab sust.rel. particle/crystal sig: one (1) tab sust.rel. particle/crystal po once a day for 10 days. disp:*10 tab sust.rel. particle/crystal(s)* refills:*0* 10. ibuprofen 600 mg tablet sig: one (1) tablet po q6h (every 6 hours) as needed. disp:*40 tablet(s)* refills:*0* discharge disposition: home with service facility: homecare discharge diagnosis: type a aortic dissection, s/p repair this admission hypertension hyperlipidemia discharge condition: good discharge instructions: please shower daily including washing incisions, no baths or swimming monitor wounds for infection -
