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: the patient is an 83-year-old gentleman with coronary artery disease (status post coronary artery bypass graft), hypercholesterolemia, hypertension, type 2 diabetes mellitus, and multi-infarct dementia who presents with intermittent chest pain times two to three days. the pain changes location and is not associated with shortness of breath; although, it is associated with an increase in fatigue and decreased oral intake. in the emergency department, the patient was found to have an irregular rhythm. on electrocardiogram he was found to be flipping from a heart rate of 30 to a heart rate of 140 to 160. the patient remained completely asymptomatic during these episodes without complaints of chest pain, palpitations, or shortness of breath. his blood pressure was for the most part in the 90's-100's, but with rates in the 30's was occasionally transiently in the 80's. past medical history: 1. coronary artery disease. (a) status post myocardial infarction. (b) coronary artery bypass graft in . 2. type 2 diabetes mellitus; complicated by peripheral neuropathy. 3. hypertension. 4. hypothyroidism. 5. hypercholesterolemia. 6. multi-infarct dementia. 7. history of transient ischemic attacks. 8. gout. 9. diverticulitis. 10. history of colonic polyps. medications on admission: 1. glyburide 5 mg by mouth twice per day. 2. levoxyl 50 mcg by mouth once per day. 3. reminyl 8 mg by mouth twice per day. 4. aspirin 81 mg by mouth once per day. 5. lopid 600 mg by mouth twice per day. 6. zocor 50 mg by mouth once per day. 7. ferrous sulfate 320 mg by mouth twice per day. 8. nitroglycerin patch 0.6 mg as needed. allergies: 1. sulfa. 2. benzodiazepines. social history: the patient lives in the alzheimer's center (which is an facility). the patient denies any history of tobacco smoking or alcohol use. he has a granddaughter who is very dedicated to him. she assists him with his medications. the patient has a very poor memory, but is otherwise independent. physical examination on presentation: physical examination on admission revealed the patient was afebrile, his heart rate was 69, his blood pressure was 105/51, his respiratory rate was 16, and his oxygen saturation was 97% on room air. physical examination was notable for a normal first heart sounds and second heart sounds, and there were clear lung sounds bilaterally. pertinent laboratory values on presentation: laboratories on admission were notable only for a creatinine of 1.4. the remainder of the patient's laboratories were within normal limits. thyroid-stimulating hormone was within normal limits. pertinent radiology/imaging: multiple electrocardiograms obtained in the emergency department showed bradycardia with a rate in the 30s and a pattern consistent with atrial bigeminy with blocked apbs as well as episodes of atrial fibrillation and episodes of typical atrial flutter with a heart rate in the 150s. a chest x-ray was clear. concise summary of hospital course: the patient was admitted to the coronary care unit for close monitoring due to his irregular rhythm and intermittent hypotension. the patient received a sdr303b dual-chamber rate-responsive pacemaker. the patient tolerated the procedure extremely well. at the time of the pacemaker placement, the patient was in a sinus rhythm. however, it was decided since he did have episodes of atrial fibrillation/atrial flutter that he would be amiodarone loaded and started on coumadin. the patient was started on coumadin following a physical therapy evaluation which showed very minimal fall risk. the patient also received 48 hours of vancomycin intravenously prophylactically. the patient was to be continued on clindamycin prophylactically as an outpatient for several more days. the patient's creatinine, which was elevated at 1.4 on admission, decreased back down to his baseline with some hydration. the patient's thyroid-stimulating hormone was also checked and was found to be within normal limits, and he was continued on his home dose of levothyroxine. prior to discharge, the patient was also started on a low dose of toprol-xl due to his history of coronary artery disease. condition at discharge: condition on discharge was stable, with a stable heart rate in the 70s to 80s, and feeling well. discharge status: the patient was to be discharged back to his extended care facility (which is alzheimer's center). the patient was to receive to assist with medication management and for blood pressure checks as well as inr checks. discharge diagnoses: 1. sick sinus syndrome. 2. status post pacemaker placement. 3. atrial fibrillation. 4. atrial flutter. 5. coronary artery disease. 6. type 2 diabetes mellitus. 7. hypertension. 8. hypothyroidism. 9. hypercholesterolemia. 10. multi-infarct dementia. 11. cerebrovascular disease. medications on discharge: 1. levothyroxine 50 mcg p.o. q.d. 2. galantamine hydrobromide (reminyl) 8 mg by mouth twice per day. 3. aspirin 81 mg by mouth once per day. 4. gemfibrozil 600 mg by mouth twice per day. 5. simvastatin 50 mg by mouth once per day. 6. sertraline 25 mg by mouth once per day. 7. docusate 100 mg by mouth twice per day. 8. ferrous sulfate 320 mg by mouth twice per day. 9. glyburide 5 mg by mouth twice per day. 10. clindamycin 300 mg by mouth q.6h. (for a total of six doses). 11. amiodarone 200 mg by mouth three times per day times one month; followed by amiodarone 200 mg by mouth once per day after the one month. 12. multivitamin one tablet by mouth every day. 13. metoprolol sustained release 25 mg by mouth once per day. 14. coumadin 2.5 mg by mouth at hour of sleep (to be started on the friday after discharge; ). discharge instructions/followup: 1. the patient was instructed to follow up with the cardiology electrophysiology device clinic on at 10 p.m. 2. the patient was instructed to follow up with his primary care physician (dr. ) in one to two weeks; he was asked to make a follow-up appointment. 3. the patient was instructed to follow up with dr. in the cardiology center on at 3 p.m. , m.d. dictated by: medquist36 d: 17:00 t: 04:46 job#: procedure: initial insertion of dual-chamber device initial insertion of transvenous leads [electrodes] into atrium and ventricle diagnoses: pure hypercholesterolemia unspecified essential hypertension diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled atrial fibrillation coronary atherosclerosis of unspecified type of vessel, native or graft aortocoronary bypass status atrial flutter old myocardial infarction sinoatrial node dysfunction 

Answer: The patient is high likely exposed to
