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: patient is a 61-year-old caucasian male with a past medical history significant for coronary artery disease status post cabg in and myocardial infarction in and , who is being admitted for sudden onset of chest pain. the patient was recently admitted to on for treatment of bilateral gangrenous feet. there was a plan for bilateral below the knee amputations. however, the patient had intermittent ventricular tachycardia during the hospitalization and was started on amiodarone. the patient was planned for cardiac catheterization prior to going bilateral below the knee amputations and during the catheterization, the patient had an acute st elevation myocardial infarction. the patient was treated with medical management. he was transferred to the ccu, where he continued to have recurrent episodes of ventricular tachycardia. the patient continued to be medically managed and was discharged to rehab. the patient is coming back on this current admission two days after the last discharge to rehab with sudden onset of chest pain described as identical to his anginal equivalent. the pain was brought on at rest and was associated with shortness of breath and radiation to the shoulder blades. there was no improvement with two sublingual nitroglycerins and the patient's blood pressure dropped into the 80s systolic. the patient continued to complain of pain in the epigastric region and described it as a squeezing sensation. he also complained of nausea and vomiting for several days prior to admission. he denies any palpitations, lightheadedness, or other symptoms. past medical history: please see previous dictation summary of admission of for further past medical history, past surgical history including allergies. medications on admission: 1. allopurinol 100 mg q.d. 2. calcium acetate 667 mg t.i.d. 3. aspirin 325 mg q.d. 4. plavix 75 mg q.d. 5. trazodone 100 mg q.h.s. 6. pravastatin 20 mg q.d. 7. klonopin 0.5 mg b.i.d. 8. protonix 40 mg q.d. 9. percocet prn. 10. senna. 11. amiodarone 400 mg b.i.d. 12. mexiletine 150 mg b.i.d. 13. multivitamin. 14. insulin glargine 15 units q.h.s. 15. humalog insulin-sliding scale. vital signs on admission: temperature 97.8, blood pressure 88/34, pulse 82, respiratory rate 16. physical exam: the patient is obese, lying in bed in no apparent distress. skin examination shows multiple scabs with dry gangrene of bilateral feet especially of the right lower extremity. oropharynx is clear with no obvious jvd and moist mucous membranes. heart examination shows a normal s1, s2 with a regular rate and rhythm with no murmurs appreciated, but distant heart sounds. lungs are clear to auscultation anteriorly. abdomen is benign. extremities showed trace edema of the bilateral lower extremities and trace to 1+ dorsalis pedis pulses bilaterally. neurologic examination is grossly intact. laboratories on admission: white count 10, hematocrit 34.1, platelets 135. inr 1.4. chemistries is significant for a chloride of 93, bicarb of 30, bun of 34, and creatinine of 5.2. initial ck was 40. chest x-ray showed no evidence of chf or pneumonia. ekg shows low voltage with normal sinus rhythm at 80 beats per minute. axis is normal. qrs is mildly prolonged. there are old st depressions in leads v2 through v4. summary of hospital course by issue: 1. coronary artery disease: the patient has flat cks and elevated troponins, however, due to the fact that he had failed revascularization on a previous cardiac catheterization, there is no plan for recatheterization. it is also likely that the elevated troponins were secondary to the patient's elevated secondary to the patient's end-stage renal disease rather than representing an acute event. the patient was managed medically. his regimen was changed so that beta-blocker was added. carvedilol was started at a low dose. he was continued on aspirin, plavix, and statin. the patient's beta-blocker dose is not able to be titrated up due to borderline blood pressure. however, he did not have any further significant chest pain, although he did complain of occasional epigastric burning, which was not clearly anginal. the patient was continued on current medical management. there is no option for interventional procedure. 2. congestive heart failure and fluid overload: on admission, the patient was found to be approximately 15 to 20 kg above his dry weight. renal service was consulted for hemodialysis, and the patient underwent two hemodialysis sessions. however, they were not able to remove significant amounts of fluid due to the fact that there was concern for ventricular arrhythmia and hypotension during dialysis. at that point, the patient was transferred to the ccu for a cvvh and removal of fluid through cvvh. the patient received several days of cvvh with effective fluid removal, however, he subsequently had a 22 beat run of ventricular tachycardia. at this point, a cvvh was stopped. the patient did not appear to be significantly fluid overloaded after that point as he continued to receive hemodialysis. his oxygenation was very good, and he did not have any other signs of heart failure. 3. rhythm: patient continued to have significant ventricular ectopy with intermittent runs of nonsustained polymorphic ventricular tachycardia. as this was thought to be due to his underlying ischemic heart disease, there is no intervention that can be performed by electrophysiology service that would be effective. the patient was continued on amiodarone and mexiletine. his mexiletine dose was increased to 250 mg b.i.d, though he continued to have intermittent short runs of nsvt. 4. end-stage renal disease: as previously mentioned, the patient had a cvvh to decrease his weight to his goal weight 120 kg. however, this was stopped to ventricular arrhythmia. the patient then underwent hemodialysis first with no fluid removal, which he tolerated well and subsequently with fluid removal of 1.6 liters on the second day, again which he tolerated well without significant episodes of hypotension or arrhythmia. the patient's cvvh catheter was removed by interventional radiology. 5. peripheral vascular disease: patient was seen by vascular surgery as he was awaiting bilateral knee amputations for his dry gangrene of both feet. due to his cardiac situation, this was not undertaken during the hospitalization. patient is to followup with his vascular surgeon, dr. after discharge to be reassessed for possible surgery for the dry gangrene. 6. diabetes mellitus: the patient's diabetes was managed per his outpatient regimen with insulin glargine, and humalog sliding scale. 7. code status: the patient was full code on admission. however, after discussion with him and his family, he was made dni only, but he did want to be resuscitated. discharge status: the patient is to be discharged to a rehab facility. discharge condition: patient was in good condition. he is afebrile, hemodynamically stable, and tolerating p.o. discharge diagnoses: 1. coronary artery disease. 2. congestive heart failure. 3. end-stage renal disease. 4. diabetes mellitus type 2. 5.
