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: history of present illness: this is a 64-year-old lady with a complicated medical history significant for the fact that she was status post c5-c6 and c6-c7 discectomies with bone graft and plate placement on . she presented with exacerbation of dizziness and the acute onset of vertigo for four days as well as five minutes of loss of consciousness. the patient was having dizziness and vertigo ever since her surgery on . she was taken to an outside hospital where workup, including cervical films, failed to determine any etiology for the syncope and vertigo. she was discharged home. on admission to , the patient continued to have dizziness and vertigo and was admitted for further investigation. past medical history: the past medical history was significant for the fact that the patient was a diabetic for the last 25 years. she had c5-c6 and c6-c7 discectomies with bone graft and metal plate placement on . she a had parotid gland tumor resection ten years ago. she had right rotator cuff surgery. she had a lumbar laminectomy in . she also had an appendectomy in the past. the patient had hypertension and hypercholesterolemia. she had a hysterectomy in the past. medications on admission: the patient was on oxycontin, vicodin, lipitor, glucophage, amaryl and trandolapril. allergies: the patient was allergic to furadantin, captopril and ethylenediamine. physical examination: on examination, the patient had a blood pressure of 118/52, a pulse of 64 per minute, a respiratory rate of 16 and an oxygen saturation of 99% on room air. she was interactive. the pulmonary examination was clear to auscultation bilaterally with no crackles or wheezes. the cardiovascular examination was a regular rate and rhythm with no murmurs, rubs or gallops. the abdomen was soft, nontender and nondistended with positive bowel sounds. neurologically, the patient was alert and oriented. affect was appropriate. attention was good. language was fluent with normal content. visual fields were intact. the fundi were normal. the pupils were normal, round and reactive. extraocular movements were full. normal facial sensation and movement were present. hearing was intact. there were normal oropharyngeal movement and sensation. the tongue was midline with no fasciculations. motor examination was normal on both the right side and the left. strength was grade 5 in all muscle groups. the right upper extremity examination was limited because of pain. pronator drift was absent. touch was intact bilaterally. pinprick, vibration and proprioception were also intact. reflexes were bilaterally present and symmetrical. plantar reflexes were downgoing. coordination was good. laboratory data: the total white blood cell count was 6500 with a hematocrit of 29 and platelet count of 213,000. prothrombin time was 13.1, partial thromboplastin time was 32.4 and inr was 1.1. chem 7 revealed a sodium of 141, potassium of 3.7, chloride of 105, bicarbonate of 25, bun of 11, creatinine of 0.5 and glucose of 176. imaging: the mri/mra report showed normal but significant artifact from cervical hardware. there was no infarct or stenosis. an angiography done on showed a left vertebral dominant system and, upon rotation of the head to the left, the diameter of the left vertebral artery decreased by 50%; there was not as significant of a decrease on the right side. there was no evidence of vertebral dissection. hospital course: the patient was admitted to the surgical intensive care unit for observation after her angiography. she continued to be investigated for her vertigo. she was seen by the neurology service. a vascular etiology for the vertigo was difficult to justify after the findings seen on the angiography. the patient was started on meclizine. her symptoms improved considerably with the meclizine and it was decided that she could be discharged to home with the meclizine. disposition: the patient was told to follow up with dr. , who was her surgeon previously, and also with the clinic. she was told to continue the meclizine until she was seen by dr. and the neurology service. she was discharged to home in stable condition. discharge diagnosis: vertigo, origin uncertain. , m.d. dictated by: medquist36 procedure: arteriography of cerebral arteries diagnoses: pure hypercholesterolemia unspecified essential hypertension diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled acute, but ill-defined, cerebrovascular disease labyrinthitis, unspecified 

Answer: The patient is high likely exposed to
