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: slurred speech, right facial droop major surgical or invasive procedure: iv thrombolysis history of present illness: the patient is a 51 yo r-handed who presented to the ed with acute onset of slurred speech. the patient was visiting his daughter who was admitted for a pe workup. while visiting her, at 4.15pm he suddenly developed slurred speech. his daughter saw that his was droopy. he was immediatly brought to the ed and the stroke team was at his bedside within a minute. his spb at that time was 170, nsr. . upon initial exam done by the stroke fellow. the pertinent positives include the following: dense r-facial umn weakness, facial sensory loss to lt on the r, a r-homonymous hemianopia (both upper and lower quadrants), and then developed r-pronator drift (deltoid 4), and a r-leg drift (4+ ip). nihss: 7. a ct head was negative for acute pathology. cta showed a decreased flow in the l-superior mca, decreased signal in l-mca. t-pa was started at 17.29 (bolus of 6.5mg; then gtt 56cc in 1 hour; total 62.5mg). i was called to see the patient to finalize the admission around 18.00. when getting the t-pa, the patient was comfortable. no headache or double vision, no nausea or vomiting. he felt tired. his face still felt somewhat numb. he had some fevers a few weeks ago, now resolved. at that time he alos had a cough. he also has had some weight loss, unclear how much and since when (now w152 pnds). otherwise, his neck is stiff at times (not now). he also has been having some chest, l-shoulder and l-arm discomfort. ros: denies any chills, visual changes, hearing changes, headache, nausea, vomiting, dysphagia, weakness, tingling, bowel-bladder dysfunction,

----- mri head: findings: diffusion images demonstrate no evidence of acute infarct. the ventricles and extra-axial spaces are normal in size. there is no midline shift, mass effect, hydrocephalus or focal signal abnormalities seen within the brain. impression: no evidence of acute infarct. ----- eeg: impression: this is a normal routine eeg obtained in wakefulness progressing to stage ii of sleep. no lateralizing or epileptiform abnormalities were seen. ------ tte: conclusions: no spontaneous echo contrast or thrombus is seen in the body of the left atrium/left atrial appendage or the body of the right atrium/right atrial appendage. premature appearance of agitated saline contrast is seen in the left atrium post-valsalva release c/w a patent foramen ovale. overall left ventricular systolic function is normal (lvef>55%). right ventricular systolic function is normal. the ascending, transverse and descending thoracic aorta are normal in diameter and free of atherosclerotic plaque. the aortic valve leaflets (3) appear structurally normal with good leaflet excursion. no masses or vegetations are seen on the aortic valve. there is no aortic valve stenosis. mild to moderate (+) aortic regurgitation is seen. the mitral valve leaflets are structurally normal. no mass or vegetation is seen on the mitral valve. mild (1+) mitral regurgitation is seen. no vegetation/mass is seen on the pulmonic valve. there is no pericardial effusion. impression: patent foramen ovale. mild-moderate aortic regurgitation with normal valve morphology. brief hospital course: the patient is a 51 yo r-handed who presented with acute onset of slurred speech, weakness, and visual loss. episode was witneesed, occurring in the hospital while visiting a family member. upon arrival to the ed a code stroke was called. on initial exam, he had a right facial droop, slurred speech, right homonymous hemianopsia, followed by r-pronator drift and r-leg drift. toe was upgoing. his nihss was 7. head ct was negative for bleed or early infarct signs. at that point, iv t-pa was administered per protocol. the patient tolerated the treatment well. his exam during t-pa remained unchanged (with clear weakness face>arm>leg). his facial weakness appeared to be a nuclear or peripheral facial, but he clearly had a field cut, sensory loss, and hemiparesis. the patient was felt to most likely have a subcortical posterior circulation stroke. he improved quickly, and by the next day he had no appreciable weakness, sensory loss, slurred speech, or visual field deficit. he did continue to have a significant right facial droop that appeared to involve his forehead, making us suspect a nuclear facial droop. he had 2 mris performed, neither of which showed any abnormality or evidence of stroke/restricted diffusion. at this point, the less likely possibility that this had been a seizure was considered and worked up. the facial droop persisted x days though, making this unlikely. an eeg was performed which was very normal. for stroke work-up, he had a1c checked and normal. lipids were checked and his ldl was less than 100 so no medication was started. in the future, a statin should be considered. a cta of the neck showed normal carotids and vertebrals. he then had a tee which showed a pfo and mild-moderate aortic regurgitation(but normal aortic valve) but no other abnormality(including no atrial septal aneurysm). cardiac telemetry while here for several days showed no abnormality. he also had blood cultures sent to evaluate for possible septic emboli. these are negative to date. there was no valvular lesion seen on tee either. esr/crp were normal. he was started on asa 325 mg daily for stroke prevention, this was changed to aggrenox at the time of discharge. he was seen by pt/ot and they felt he was safe to return home. on discharge, he was back to his normal baseline other than his right facial droop which was persistent. he was swallowing normally. he will follow up with his pcp and in the stroke clinic. he will need a hypercoagulable work-up sent at his first follow-up. consider obtaining a 2 week cardiac event monitor to continue to screen for arrhythmia. also consider ct chest/abd/pelvis to rule out malignancy as a cause of hypercoagulability. in addition, he will need to have a contrast brain mri performed as an outpatient before his follow-up to confirm the absence of any enhancing lesion that may explain his symptoms(especially as seizure is still a remote possibility). hiv testing was performed and pending at time of discharge. medications on admission: - none discharge medications: 1. aspirin 325 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 2. aggrenox 1 capsule sig: one (1) capsule po bid discharge disposition: home discharge diagnosis: probable stroke discharge condition: stable. he continued to have a right facial droop, but was otherwise at his baseline. discharge instructions: please call your doctor or return to the hospital if you have any new weakness, numbness, tingling, trouble seeing/hearing, trouble swallowing, fever, headache, dizziness, or if you pass out. please take an aspirin daily for stroke prevention. followup instructions: please call your pcp for appointment in weeks ---- please call to schedule a follow-up appointment in the neurology clinic with dr and dr in weeks ---- please call to schedule your mri as an outpatient to be done before your neurology appointment. procedure: diagnostic ultrasound of heart injection or infusion of thrombolytic agent diagnoses: cerebral artery occlusion, unspecified with cerebral infarction
