 Medical Report: past medical history: 1. diabetes times 25 years. 2. hypertension. past surgical history: amputation of the right first toe. allergies: the patient has no known drug allergies. admission medications: 1. glyburide. 2. metformin. 3. lisinopril. 4. norvasc. family history: noncontributory. social history: the patient is a retired school teacher. he is a widower. he lives with his daughter in . he smokes two cigars per day. he has an alcoholic drink every other day. physical examination on admission: vital signs: temperature 97.1, pulse 68, respirations 18, blood pressure 149/65, 02 saturation equals 98% on room air. general: the patient was an alert, cooperative white male in no acute distress. heent: normocephalic, atraumatic. the oropharynx was clear. neck: range of motion within normal limits. carotids palpable. bruit on the left. chest: heart regular rate and rhythm without murmur. lungs: clear bilaterally. abdomen: soft, nontender, nondistended. extremities: feet equally warm. well healed first toe amputation site. pulse examination: carotids, radials, and femoral pulses were 2+ bilaterally. right popliteal artery has a doppler signal. left popliteal artery is 1+. dp and pt pulses on the right have triphasic doppler signals. the left dp and pt pulses are palpable. neurologic: the patient was alert and oriented times three. motor sensory function intact. laboratory/radiologic data: wbc 8.8, hematocrit 37, platelets 143,000. pt 13.4, ptt 27.8, inr 1.2. sodium 139, potassium 4.1, chloride 108, c02 25, bun 22, creatinine 1.1, glucose 111. ekg showed a normal sinus rhythm at a rate of 60. no st or t wave changes. chest x-ray showed no acute pulmonary disease. hospital course: the patient was admitted to the neuromedicine service on . mri/mra showed a left watershed stroke in the left mca territory and a critical left internal carotid artery stenosis. duplex ultrasound showed an 80-99% left ica stenosis. arteriogram done on confirmed the duplex ultrasound study. the patient was maintained on iv heparin. on , the patient underwent an uneventful left carotid endarterectomy. on postoperative day number one, the patient was alert, his speech was fluent and his comprehension was intact. his face was symmetrical, his tongue was in the midline, and extraocular movements were intact. the patient was moving upper and lower extremities without difficulty. the patient was discharged home on postoperative day number one and instructed to follow-up with dr. in the office in ten days for surgical staple removal. the patient was also instructed to follow-up with neurology, dr. , in two to three months at . he was also instructed to follow-up with his primary care physician regarding his diabetes and hypertension. discharge medications: 1. plavix 75 mg p.o. q.d. 2. aspirin 325 mg p.o. q.d. 3. glyburide 5 mg p.o. b.i.d. 4. metformin 500 mg p.o. b.i.d. 5. lisinopril 10 mg p.o. q.d. 6. amlodipine 5 mg p.o. q.d. condition at discharge: satisfactory. disposition: home. primary diagnosis: 1. symptomatic carotid artery stenosis. 2. left carotid endarterectomy on . secondary diagnosis: 1. diabetes. 2. hypertension. , m.d. dictated by: medquist36 procedure: diagnostic ultrasound of heart endarterectomy, other vessels of head and neck diagnoses: unspecified essential hypertension diabetes with other specified manifestations, type ii or unspecified type, uncontrolled background diabetic retinopathy occlusion and stenosis of carotid artery with cerebral infarction diabetes with ophthalmic manifestations, type ii or unspecified type, uncontrolled 

Answer: The patient is high likely exposed to
