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: transfer from osh for subarachnoid hemorrhage major surgical or invasive procedure: none history of present illness: pt is an 80 year old left handed male with history of hypertension now presenting with subacute r pca infarction. he was attempting to drive to the mall this morning and took a wrong turn, which was unusual for him. unclear if the mall was supposed to be on the left side of the street. he did not feel disoriented, but sensed that something was wrong as he was unable to find the mall. he went to hospital where head ct revealed r parietal sah. he was transferred here and evaluated by neurosurgery, whereupon head ct/cta revealed completed r pca infarction with overlying area of punctate sah. on further history the patient reports a sense of right eye pulsating/throbbing feeling yesterday. he may have taken extra aspirin tablets to treat the pain. this sensation has since subsided. at the moment the pt reports a very mild headache in the right temporal region. he does not normally get headaches. he notably denies any apparent neurologic deficit. he

the left side. line bisection task is normal, however pt appears to have missed two lines he needed to bisect on the far left side. cranial nerves: olfaction not tested. perrl 3 to 2mm and brisk.

right frontal lobe. echo: no lv thrombus or asd seen. normal global and regional biventricular systolic function. mri: 1. right pca-distribution infarct and small amount of overlying subarachnoid hemorrhage, unchanged. no abnormal intracranial enhancement. 2. extensive plaque as detailed above at the carotid bulbs and internal carotid arteries, bilaterally. recommend son correlation to better characterize extent and ulceration of plaque, and severity of narrowing. 3. fenestrated anterior communicating artery, and aplastic right pica with dominant left pica. brief hospital course: patient is an 80 year old man with a h/o htn, presents after he felt "disoriented" while driving. had mild left frontal ha yesterday but denies any prior ha; does not acknowledge any visual problems. on exam, awake, alert and oriented to date and locale. speech fluent with normal language functions. misses words on the left half of page while . left incongrous hemianopia. face symmetrical. normal strength and co ordination. ct head showed a right mesiotemporal and occipital infarct and a small right posterior frontal convexal sah plus r-p2 occlusion. right temporo-occipital infarction was likely embolic. the etiology of sah is unclear-no clear vasospam or evidence of any vascular malformation on cta was seen. this was not an aneurysmal hemorrhage but may be due to amyloid angiopathy. after mri ruling out any abnormal vasculature, patient was started on plavix since patient was already on asa at home. patient was evaluated per pt/ot who reccomended outpatient ot. given that patient is currently not safe for discharge home alone, he went to stay with his girlfriend and continue outpatient ot. he was strictly instructed not to drive given his hemianopia and he will be following up with dr. as outpatient. medications on admission: atenolol 100mg daily hctz 25mg daily aspirin 81mg daily lisinopril verapamil 120mg daily discharge medications: 1. atenolol 100 mg tablet sig: one (1) tablet po once a day. 2. lisinopril 40 mg tablet sig: one (1) tablet po once a day. 3. clopidogrel 75 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 4. verapamil 120

visual field cut discharge disposition: home discharge diagnosis: r pca distribution stroke small r parietal subarachnoid hemorrhage likely amyloid angiopathy hypertension with chronic renal insufficiency discharge condition: stable - left hemianopia but normal strength. discharge instructions: you were transferred from hospital after being found to have small r parietal subarachnoid hemorrhage. you presented to the outside hospital with feeling lost while driving and right temporal headache. you were evaluated per neurology and found to have left sided visual field cut and imaging showed that you had r occipital and medial-temporal stroke in the r pca distribution. you were initially admitted to the icu due to the bleed but you remained stable except for left hemianopia hence transferred to the neurology floor on hospital day #3. mri and further evaluation showed no underlying abnormality causing the bleed and you were switched from aspirin to plavix for better stroke prevention. you were evaluated per occupational and physical therapy who felt that you were safe to discharge home but with supervision hence you will be discharged to stay with your significant other/friend. will also be given prescription for occupational therapy as outpatient as well given the visual field cut. since you have significant visual field cut from the stroke, you may and cannot drive. please take your meds as prescribed and follow-up with dr. within 2~3 weeks of discharge and dr. (neurology) as scheduled. please call 911 or go to the nearest ed if you have new weakness/numbness, speech problems including slurring, and new visual issues including double vision, blurry vision or spinning sensation. followup instructions: provider: , md phone: date/time: 11:00 clinical center md procedure: arteriography of cerebral arteries magnetic resonance imaging of brain and brain stem computerized axial tomography of head diagnoses: acute kidney failure, unspecified hypertensive chronic kidney disease, unspecified, with chronic kidney disease stage i through stage iv, or unspecified subarachnoid hemorrhage personal history of tobacco use unspecified glaucoma chronic kidney disease, unspecified occlusion and stenosis of carotid artery with cerebral infarction homonymous bilateral field defects cataract extraction status 

Answer: The patient is high likely exposed to
