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: tapazole attending: chief complaint: dysarthria, unsteady gait and falling to the right major surgical or invasive procedure: none history of present illness: this is a rh year old with a past medical history significant for htn, distant breast ca, who presents with sudden onset "leaning to the right," and "incoherent speech" at 1:45pm . she says that she "didn't feel right" most of the day, though did not tell her husband. she did not have fever, n/v, diarrhea, sob, cp or numbness or weakness. she made lunch for her husband, though herself ate only dry toast and tea. around 1:45pm she went to lie down for a nap (not unusual for her, though she does note at the time she was vaguely "not feeling well"). her husband did not notice anything out of the ordinary at that time. when she awoke from the nap at 3:40pm, she noted that she was leaning to the right and had slurred speech. her husband said her speech was nearly "incoherent" - though he could in fact, understand what she was saying, she was having no word-finding difficulty, and she was having no comprehension problems. she was having dysarthria fairly severely, however. she says she did not have any other new visual disturbances or numbness. her husband immediately called ems, and they noted right sided weakness in the ambulance and she was also vomiting in the ambulance. on arrival to the ed - she said that although the world was not spinning, she felt as though she was spinning (though later said she no longer had the feeling after coming out of the head ct around 5pm). she says she has never had a stroke before, and has had no recent illness. she says that other than her speech still being slurred, she is having no other current problems. she and her husband do note that she monitors her own bp at home, and generally she has sbps in 150s. past medical history: 1.htn 2.breast ca 25yrs ago 3.s/p recent right eye surgery (says for cataracts) 4. hx of thyroid nodule social history: no smoking, no etoh or other drug use. lives with her husband. brief hospital course: mrs is a 79 year old woman who presented with mild right arm cerebellar symptoms and a recent history of slurred speech. her mri revealed a right cerebellar stroke in a right pica distribution. there was also decreased flow in the right aica and she did have an associated auditory symptom at onset. on her second day of admission she was somnolent and a repeat hct showed an increased size of the lateral and third ventricles with effacement of the fourth. she was transferred to the nicu for observation and started on mannitol. she was slightly more alert the following day, and therefore, transferred back to and weaned off of the mannitol. she was later found to be in a-fib/a-flutter to the 120s-130s. she was rate controlled with diltiazem and cardiology was consulted. they suggested anticoagulation, however, due to the size of the infarct we decided to not heparinize but to instead start on 5mg of coumadin qday and let the inr gradually increase to a goal of . she was discharged to for acute rehab on . pertinent studies: triglycerides 87 mg/dl 0 - 149 cholesterol, hdl 65 mg/dl cholesterol ratio (total/hdl) 2.7 ratio cholesterol, ldl, calculated 95 mg/dl 0 - 129 transthoracic echo cardiogram: the left atrium is mildly dilated. left ventricular wall thicknesses are normal. the left ventricular cavity size is normal. overall left ventricular systolic function is normal (lvef>55%). right ventricular chamber size and free wall motion are normal. the aortic valve leaflets (3) are mildly thickened. there is mild aortic valve stenosis. mild to moderate (+) aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. mild (1+) mitral regurgitation is seen. there is mild pulmonary artery systolic hypertension. there is no pericardial effusion. no cardiac source of embolus is identified. medications on admission: 1. atenolol 75 mg qday 2. zestril 10 mg qday discharge medications: 1. aspirin 81 mg tablet sig: one (1) tablet po once a day. 2. pantoprazole sodium 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po q24h (every 24 hours). 3. dorzolamide-timolol 2-0.5 % drops sig: one (1) drop ophthalmic (2 times a day). 4. brimonidine tartrate 0.2 % drops sig: one (1) drop ophthalmic q8h (every 8 hours). 5. prednisolone acetate 1 % drops, suspension sig: one (1) drop ophthalmic (2 times a day). 6. atorvastatin calcium 10 mg tablet sig: one (1) tablet po daily (daily). 7. warfarin sodium 5 mg tablet sig: one (1) tablet po qhs (once a day (at bedtime)). 8. metoprolol tartrate 25 mg tablet sig: one (1) tablet po bid (2 times a day). 9. lisinopril 5 mg tablet sig: one (1) tablet po daily (daily). 10. senna 8.6 mg tablet sig: one (1) tablet po bid (2 times a day) as needed. 11. acetaminophen 325 mg tablet sig: 1-2 tablets po q4-6h (every 4 to 6 hours) as needed. 12. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). discharge disposition: extended care facility: & rehab center - discharge diagnosis: right pca territory cerebellar infarct atrial fibrilation discharge condition: well but would benefit from acute rehab discharge instructions: return for suddenly worsening ataxia, slurred speech, somnolence, focal weakness or numbness. followup instructions: 1) dr. in neurology - call for appointment next appointment after discharge from 2) call pcp for an appointment md, procedure: diagnostic ultrasound of heart diagnoses: unspecified essential hypertension atrial fibrillation personal history of malignant neoplasm of breast mitral valve insufficiency and aortic valve insufficiency atrial flutter cerebral embolism with cerebral infarction
