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 year old male with good baseline activities of daily living functions with a history of coronary artery disease, with acute myocardial infarction in status post successful primary intervention with left ejection fraction of 30% after myocardial infarction, who has done well since procedures with only minor recurrence of chest pain and who also has a history of colon cancer status post hemicolectomy. over the last year, he has developed a prolonged pr interval, a right bundle branch block, left anterior fascicular block that has been noted on electrocardiograms. prior to admission, the patient was able to walk regularly and be active, but on the day of admission at around noon, the patient had severe lightheadedness and dizziness while walking. he denied chest pain, shortness of breath, nausea, vomiting or diaphoresis at that time. the patient had significant symptoms while standing, walking and even when trying to sit upright; after the initial episode of dizziness, however, he was asymptomatic while resting in bed in a prone position. a bystander at the scene of the initial episode was savvy enough to check a pulse which was 37 at the time of onset of symptoms. in the emergency room, the patient had a pulse ranging from 32 to 34 with a blood pressure in the 110 to 120 over 40 to 50 range without symptoms. he had no chest pain, no shortness of breath, and no diaphoresis. the patient denies recent medication changes. he has had no recent fevers, chills, sweats, cough, prior episodes of dizziness, paroxysmal nocturnal dyspnea, orthopnea, nausea, vomiting or abdominal pain. past medical history: 1. coronary artery disease. 2. colon cancer. 3. hypertension. 4. hypercholesterolemia. 5. bullous pemphigus. 6. glaucoma. 7. cataracts. physical examination: his physical examination on admission was vital signs of blood pressure 113/48; heart rate 32 to 34; o2 saturation 99% on room air; respiratory rate 14. general examination was an elderly male that was alert and oriented times three in no acute distress. heent: pupils were equal, round and reactive to light with accommodation. his mucous membranes were moist. oropharynx was clear. his cranial nerves ii through xii were intact. neck: no venous pulsation, no thyromegaly. cardiovascular examination showed bradycardia, irregular rhythm, normal s1 and s2 but no murmurs, rubs or gallops. pulmonary examination clear to auscultation bilaterally; no wheezes. abdomen was soft, nontender; he had active bowel sounds. extremities cool to touch; no cyanosis, no edema, one plus radial pulse, one plus posterior tibial pulse and one plus dorsalis pedis pulses bilaterally. laboratory: on admission, white blood cell count 9.0, hemoglobin 14.0, hematocrit 14.1, neutrophils 74%, lymphocytes 18%, monocytes 6% and eosinophils 1%. his platelet count was 163. pt was 12.4, inr 1.1, ptt 34.3. his sodium 140, potassium 4.8, chloride 105, bicarbonate 24, bun 53, creatinine 1.7. ck was 43, ck mb was 1. his troponin was less than 0.3 and cpk was, as i said, 43. his chest x-ray impression was: much improved appearance compared to prior examination on , without congestive heart failure or pneumonia. ekg showed undifferentiated second degree heart block with 2:1 conduction pattern and occasional runs of second degree type i wenckebach block. ekg also showed profound bradycardia. there was no evidence of st elevation or other signs of ischemia. hospital course: 1. bradycardia: on the evening of admission, a central venous catheterization cordis, was placed and transvenous pacing was induced at a rate of 80. this pacing was done for six to eight hours prior to the patient being sent to the electrophysiology laboratory where he had a permanent pacer placed on without complications. the patient's pacemaker was interrogated both after the procedure and the day following procedure, which showed appropriate pacing. the patient received two days of kefzol and was sent home with one day of p.o. keflex for post-procedure antibiotic prophylaxis. the patient had an appropriate paced rhythm in the range of 60 to 80 throughout the remainder of his hospitalization. he was hemodynamically stable throughout the rest of his hospitalization. he had no new complaints. 2. activity: the patient's activity is to be monitored for six to eight weeks, avoiding raising his left arm above his shoulder due to replacement from the pacemaker. the patient will have a visiting nurse which was arranged by the care coordinator, to visit on a daily basis, to help him with his daily functions in light of his arm restrictions. 3. renal: the patient's creatinine elevated to 1.7 on the day of admission, which was thought to be from low p.o. intake and low ejection fraction secondary to bradycardia. intravenous hydration followed by p.o. hydration, led to normalization of the patient's creatinine to 1.1. it was later learned that the patient had a baseline slightly inhibited renal function which was evident in his hospital course. 4. endocrine: the patient was maintained on his maintenance dose of prednisone at 5 mg p.o. for his diagnosis of bullous pemphigus. it was not thought that he needed any stress dose steroids as the 5 mg dose was not suppressing his pituitary access. condition at discharge: good. disposition: the patient was discharged home. discharge diagnoses: 1. tri-fascicular heart block. discharge medications: 1. plavix 75 mg q. day. 2. cozaar 25 mg q. day. 3. aspirin 325 mg q. day. 4. zantac 150 mg twice a day. 5. latanoprost 0.005%, place one drop in right eye at bed time. 6. metoprolol 25 q. day. 7. potassium 20 mg q. day. 8. sertraline 50 mg q. day. 9. lipitor 10 mg q. day. 10. prednisone 5 mg q. day. 11. keflex 500 mg q. eight hours times four doses. , m.d. dictated by: medquist36 d: 21:36 t: 12:07 job#: procedure: initial insertion of dual-chamber device initial insertion of transvenous leads [electrodes] into atrium and ventricle diagnoses: pure hypercholesterolemia old myocardial infarction personal history of malignant neoplasm of large intestine other second degree atrioventricular block pemphigoid 

Answer: The patient is high likely exposed to
