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: vision loss. major surgical or invasive procedure: none. history of present illness: the pt. is a 71 year-old right-handed gentleman who presented with acute onset right-sided visual loss. he was in his usual state of health until 8:30 this evening when he developed the acute onset of right-sided visual loss. his daughter called an ophthalmologist who lives in the neighborhood who came to assess the pt. he apparently diagnosed a right hemianopia and advised calling ems over concern for stroke. the pt was transported via ems to ed. code stroke was called on arrival (10:13pm), the neurology resident was at bedside by 10:15pm. nihss was performed immediately and was 2 (for complete hemianopia). blood was drawn and he was taken emergently for ct scan of the head. this revealed no ich. the risks and benefits of iv tpa were discussed with the pt by the stroke fellow. it was decided to administer tpa given the potential disability caused by this deficit. iv bolus of tpa (based on wt of 70kg) was administered at 11:18pm. the pt otherwise offered no complaints. he did state, however, that all night last night and until roughly 11:30am, he was experiencing palpitations, which he has been known to experience in the past. the pt denied headache, blurred vision, diplopia, dysarthria, dysphagia, lightheadedness, vertigo, tinnitus or hearing difficulty. denied difficulties producing or comprehending speech. denied focal weakness, numbness, parasthesiae. no bowel or bladder incontinence or retention. denied difficulty with gait. on review of systems, the pt denied recent fever or chills. no night sweats or recent weight loss or gain. denied cough, shortness of breath. denied chest pain or tightness. denied nausea, vomiting, diarrhea, constipation or abdominal pain. no recent change in bowel or bladder habits. no dysuria. denied arthralgias or myalgias. past medical history: -paroxysmal atrial fibrillation -asthma -bph social history: pt is from and is here visiting his daughter. is a virologist (md, phd). no history of tobacco, alcohol, illicit drug use.

was no apraxia or neglect. -cranial nerves: olfaction not tested. perrl 3 to 2mm and brisk. on confrontation, there is a complete right visual field hemianopia in the right eye and more of a crescenteric right visual field deficit in the left eye (i.e. it is noncongruous). there is no ptosis bilaterally. funduscopic exam revealed no papilledema, exudates, or hemorrhages. eomi without nystagmus. normal saccades. facial sensation intact to pinprick. no facial droop, facial musculature symmetric. hearing intact to finger-rub bilaterally. palate elevates symmetrically. strength in trapezii and scm bilaterally. tongue protrudes in midline. -motor: normal bulk, tone throughout. strength was full throughout. no pronator drift bilaterally. no adventitious movements noted. -sensory: no deficits to light touch throughout. no extinction to dss. -coordination: no intention tremor, dysdiadochokinesia noted. no dysmetria on fnf or hks bilaterally. -dtrs: tri pat ach l 2 2 2 2 1 r 2 2

signal abnormalities seen in the medial left occipital lobe which is only visualized on the diffusion images without corresponding abnormalities on the adc map or on the flair or t2-weighted images. these findings are suspicious for an acute infarct. clinical correlation and followup examination are recommended. there is mild prominence of sulci. subtle periventricular hyperintensities are noted due to small vessel disease. there is no midline shift or hydrocephalus. mucosal thickening is seen in both maxillary sinuses. impression: subtle diffusion abnormality in the medial left occipital lobe suspicious for an early infarct. consider clinical correlation and followup. mra of the head: head mra demonstrates normal flow signal within the arteries of anterior and posterior circulation. normal flow signal is seen in both posterior cerebral arteries. impression: normal mra of the head. tte: the left atrium is normal in size. left ventricular wall thicknesses are normal. the left ventricular cavity size is normal. overall left ventricular systolic function is normal (lvef>55%). tissue velocity imaging demonstrates an e/e' <8 suggesting a normal left ventricular filling pressure (<12mmhg). right ventricular chamber size and free wall motion are normal. the ascending aorta is mildly dilated. the aortic valve leaflets (3) are mildly thickened. there is no aortic valve stenosis. mild (1+) aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. trivial mitral regurgitation is seen. the tricuspid valve leaflets are mildly thickened. there is no pericardial effusion. impression: no cardiac source of embolus other history of paf found. however, transthoracic echo not adequate to assess for atrial thrombus. carotid ultrasound: prelim read was no significant stenosis bilaterally. brief hospital course: 1. left occipital stroke: exam on presentation was notable for a noncongruous right homonymous hemianopia. due to the potential disability derived from this deficit, the decision was made to give the pt iv tpa in the emergency department. he was therefore admitted to the icu for observation 24 hours. unfortunately, his deficits did not resolve. mri demonstrated an area of restricted diffusion in the left occipital lobe. mra of the brain was normal. etiology was felt to be cardioembolic given paroxysmal atrial fibrillation. he was started on warfarin. tte demonstrated no thrombus. carotid ultrasonography was normal. he was found to be hyperlipidemic and was started on atrovastatin. he was also found to have an elevated glycated hemoglobin and fasting glucose. this should be followed-up with his pcp on his return to . 2. paroxysmal atrial fibrillation: this was felt to be the etiology of the stroke. he was started on warfarin. he was also continued on sotalol. 3. hyperlipidemia: the pt was found to have elevated total cholesterol and ldl. he was started on 10mg of atorvastatin daily. 4. diabetes mellitus: the pt was found to have an elevated glycated hemoglobin and fasting serum glucose. this should be followed-up with his pcp on his return to . 5. asthma: the pt was continued on albuterol. 6. bph: the pt was continued on tamsulosin. medications on admission: -sotalol -tamsulosin -albuterol discharge medications: 1. warfarin 5 mg tablet sig: one (1) tablet po hs (at bedtime). disp:*30 tablet(s)* refills:*2* 2. tamsulosin 0.4 mg capsule, sust. release 24hr sig: one (1) capsule, sust. release 24hr po hs (at bedtime). 3. sotalol 80 mg tablet sig: one (1) tablet po bid (2 times a day). 4. atorvastatin 10 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 5. outpatient work pt, inr. discharge disposition: home discharge diagnosis: -left occipital stroke -paroxysmal atrial fibrillation -hyperlipidemia -type 2 diabetes mellitus discharge condition: stable. neurologic examination notable for right homonymous hemianopia. discharge instructions: please take all medications as prescribed. please follow-up with your primary care doctor upon your return to . please have your inr checked on thursday so that adjustments can be made to your coumadin dose as needed. if you experience worsening vision, difficulties with speech, weakness, numbness or other concerning symptoms, please return to the emergency department for evaluation. followup instructions: please follow-up with your primary care doctor upon your return to . please have your inr checked on thursday so that adjustments can be made to your coumadin dose as needed. md, procedure: injection or infusion of thrombolytic agent diagnoses: diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled atrial fibrillation asthma,
