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: briefly, patient is an 80-year-old male with a history of coronary artery disease, hypertension, type 2 diabetes, gastroesophageal reflux disease, subacute bacterial endocarditis who presented with chest pain in the setting of taking viagra. this was associated with shortness of breath with no nausea, vomiting, diaphoresis, palpitations, or lightheadedness. patient was found to have a new right bundle branch block with q-wave inversions in lead iii, avf, and v1 through v4 with twf in v5 through v6 and with no ekg to compare. patient underwent cardiac catheterization and had stent placed to left anterior descending. the coronary angiography revealed a right dominant system with lmca that was normal, left anterior descending with minor disease, left circumflex with 80% lesion at d2 with timi 2 flow, right coronary artery with 50% mid lesion. post catheterization patient was noted to have mobitz ii rhythm on telemetry and hence underwent pacemaker placement on . subsequent to this patient was transferred to the service for further observation and care. past medical history: 1. coronary artery disease. 2. gastroesophageal reflux disease. 3. esophageal strictures. 4. hypertension. 5. type 2 diabetes. 6. hepatitis c. 7. subacute bacterial endocarditis 10 years ago. 8. status post hernia repair. 9. status post right wrist surgery with hardware placement. medications on transfer: 1. vancomycin 1 gram q. 12 hours times four doses. 2. oxycodone p.r.n. 3. captopril 12.5 mg one p.o. t.i.d. 4. metoprolol 50 mg one p.o. b.i.d. 5. celexa 20 mg one p.o. q.d. 6. lorazepam 0.25 mg one p.o. q.d. 7. senna p.r.n. 8. docusate p.r.n. 9. protonix 40 mg one p.o. q.d. 10. regular insulin sliding scale. 11. plavix 75 mg one p.o. q.d. 12. aspirin 325 mg one p.o. q.d. allergies: patient has no known drug allergies. social history: he is a retired compositor. history of intravenous drug use; none in the last six years. prior cocaine use; none in the last six years. remote smoking history; quit 60 years ago. history of heavy etoh use but none in the last six years. lives alone. separated from second wife. family history: significant for father with cerebrovascular accident at age 72. son had myocardial infarction in 50s and daughter had lung cancer. physical examination: vitals on admission to the service are blood pressure 170/86, pulse 68, respiratory rate 16, satting at 98% on room air. patient is afebrile with temperature 97.8. generally, the patient is in no acute distress, is alert and oriented times three. heent is normocephalic, atraumatic. extraocular muscles are intact. oropharynx is clear with moist mucous membranes. neck is supple with no jugular venous distention. heart is regular rate and rhythm. pacemaker placement is clean, dry, and intact with no evidence of oozing or hematoma. lungs are clear to auscultation bilaterally. abdomen is soft, nontender, nondistended with normoactive bowel sounds. extremities are free of any clubbing, cyanosis, or edema. neurologic exam: cranial nerves ii-xii are intact. strength is and symmetric. reflexes are intact and symmetric. toes are downgoing. hospital course by system: 1. cardiovascular: patient was continued on aspirin, plavix, beta blocker, and captopril with good blood pressure control. his initial hypertension was felt to be secondary to periprocedure stress. during his hospitalization on the service, however, his angiotensin-converting enzyme was titrated up and his beta blocker was changed to t.i.d. dosing. 2. for mobitz ii rhythm patient was status post pacemaker. his pacemaker was interrogated on . additionally, a chest x-ray revealed proper placement. patient received four doses of vancomycin and had no other abnormalities that were noted. 3. for diabetes patient was continued on a regular insulin sliding scale. 4. gastrointestinal: patient was maintained on a proton pump inhibitor and bowel regimen. 5. psychiatry: patient was maintained on celexa as well as lorazepam. final diagnoses: 1. coronary artery disease status post catheterization, status post stent to left anterior descending, and status post pacemaker placement. 2. coronary artery disease. 3. gastroesophageal reflux disease. 4. hypertension. discharge instructions: 1. , r.n., , r.n. at the cardiac center on at 3 p.m. 2. audiology at the otolaryngology building on at 3 p.m. 3. , r.n. at the dermatology center on at 2:20 p.m. 4. patient is also to follow up in the electrophysiology clinic at on . 5. the patient was advised that he is not to take a shower for one week. discharge medications: 1. aspirin 325 mg one p.o. q.d. 2. plavix 75 mg one p.o. q.d. 3. pantoprazole 40 mg one p.o. q.d. 4. citalopram 20 mg one p.o. q.d. 5. captopril 25 mg one p.o. t.i.d. 6. metoprolol 50 mg one p.o. t.i.d. disposition: home. discharge condition: stable, stable on room air, is able to ambulate without difficulty, is having no further ectopy on telemetry, is tolerating a regular diet, has had no further episodes of chest pain, palpitations, or other cardiovascular complaints. , m.d. dictated by: medquist36 d: 11:11 t: 09:20 job#: procedure: insertion of non-drug-eluting coronary artery stent(s) coronary arteriography using two catheters injection or infusion of platelet inhibitor catheter based invasive electrophysiologic testing initial insertion of dual-chamber device initial insertion of transvenous leads [electrodes] into atrium and ventricle insertion of temporary transvenous pacemaker system right heart cardiac catheterization diagnoses: nephritis and nephropathy, not specified as acute or chronic, in diseases classified elsewhere esophageal reflux unspecified essential hypertension acute myocardial infarction of other anterior wall, initial episode of care cardiac complications, not elsewhere classified atrioventricular block, complete cardiac catheterization as the cause of abnormal reaction of patient, or of later complication, without mention of misadventure at time of procedure acute hepatitis c without mention of hepatic coma diabetes with renal manifestations, type ii or unspecified type, not stated as uncontrolled 

Answer: The patient is high likely exposed to
