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 76-year-old white male presented to his doctor prior to initiating an exercise program. he was noted to have an abnormal ekg and was referred for an exercise tolerance test which was stopped due to the patient's fatigue. imaging revealed an ef of 37 percent, moderate reversible inferior defect, and an echocardiogram showed a dilated ra and la with an ef of 45-50 percent. he was referred for cardiac catheterization which he underwent on at which revealed an ef of 50 percent, normal left main, 90 percent rca stenosis, 90 percent proximal lad stenosis, 90 percent distal lad stenosis, 90 percent diagonal i stenosis, and 100 percent om1 stenosis. he is now admitted for cardiac catheterization. past medical history: 1. history of hypertension. 2. history of insulin-dependent diabetes for 50 years. 3. history of hypercholesterolemia. 4. history of obesity. 5. history of first-degree av block with occasional second- degree type i. 6. history of bph. 7. history of bulbar urethral stricture. 8. status post bilateral cataract surgery. 9. status post laser eye surgery. 10. status post ercp. 11. status post cholecystectomy. 12. status post left rib fractures times two. admission medications: 1. insulin 70/30 66 units q.a.m., 10 units q.p.m. if blood sugar is greater than 280. 2. hydrochlorothiazide 50 mg p.o. q.d. 3. glucophage 500 mg p.o. b.i.d. 4. lisinopril 10 mg p.o. q.d. 5. doxazosin 1 mg p.o. q.h.s. 6. toprol xl 12.5 mg p.o. b.i.d. 7. lipitor 10 mg p.o. q.d. 8. aspirin 1 p.o. q.d. 9. multivitamin one p.o. q.d. social history: he is married and lives with his wife. does not smoke cigarettes. he does not drink alcohol. allergies: the patient has no known drug allergies. review of systems: significant for bilateral pedal edema, pain in the back of his calf and feet with routine ambulation, dizziness when standing. physical examination: general: the patient is an elderly white male in no apparent distress. vital signs: pulse 75 with first-degree av block and frequent pacs and pvcs. blood pressure 154/195, respiratory rate 10. heent: normocephalic and atraumatic. the extraocular movements were intact. the oropharynx was benign. neck: supple, full range of motion. no lymphadenopathy or thyromegaly. carotids were 2+ and equal bilaterally without bruits. lungs: clear to auscultation and percussion. cardiovascular: irregularly/irregular distant rate and rhythm with distant heart sounds. abdomen: obese, soft, nontender, with positive bowel sounds. well healed midline surgical scar. no masses or hepatosplenomegaly, nontender. extremities: bilateral lower extremity 2+ pitting edema. no clubbing or cyanosis. the pulses were 1+ and equal bilaterally throughout with the exception of 2+ radials and pts and dps. neurologic: nonfocal. hospital course: on , the patient underwent a cabg times four with saphenous vein grafts to the diagonal, lad, om and pda. the cross clamp time was 63 minutes, total bypass time 106 minutes. he was transferred to the csru on neo-synephrine and propofol. he was extubated on his postoperative night. on postoperative day number one, he was transfused 1 unit of cells. on postoperative day number two, he went into atrial fibrillation and was started on amiodarone. he then later had a low cardiac index and was started on dobutamine and his chest tubes were discontinued on postoperative day number two. he received another unit of blood on postoperative day number three and was started on heparinization for atrial fibrillation. his dobutamine was discontinued on postoperative day number four. he required aggressive respiratory therapy, diuresis, and physical therapy. he was transferred to the floor on postoperative day number seven. he continued to require aggressive rehabilitation. we also obtained a renal consult as his creatinine went up to 2, but this eventually resolved. he was slowly progressing and on postoperative day number nine, he experienced an asystolic arrest, was intubated, transferred back to the unit, had his amiodarone and lopressor discontinued and had a temporary wire placed. he intermittently had some left lower lobe collapse, had to be bronchoscoped, required aggressive respiratory therapy. he also was on dopamine for his renal issues. he was treated with a ten day course of levofloxacin. he was followed by ep and was to have a permanent pacemaker but his white count was elevated so they had to wait for this to resolve. he was extubated. on , postoperative day number 21, he had a permanent pacer placed successfully. on postoperative day number 22, he was transferred back to the floor and anticoagulated with heparin and coumadin. he continued to progress. on postoperative day number 26, he was discharged to rehabilitation in stable condition. laboratory data on discharge: white count 9,100, hematocrit 26.6, platelets 250,000. sodium 144, potassium 5.1, chloride 108, c02 27, bun 33, creatinine 1.5, blood sugar 118. medications on discharge: 1. cardura 1 mg p.o. q.h.s. 2. combivent inhaler two puffs every four hours. 3. glucophage 500 mg p.o. b.i.d. 4. aspirin 81 mg p.o. q.d. 5. coumadin 4 mg p.o. q.d. 6. lipitor 10 mg p.o. q.d. 7. amiodarone 400 mg p.o. b.i.d. for four days and then decrease to 400 mg p.o. q.d. for seven days, and then decrease to 200 mg p.o. q.d. 8. insulin 70/30 20 units q.p.m. and regular insulin sliding scale. 9. multivitamin one p.o. q.d. follow up: the patient is to follow-up with the device clinic on and make an appointment with dr. in one to two weeks and dr. in six weeks. discharge diagnoses: 1. coronary artery disease. 2. atrial fibrillation. 3. bradycardia. 4. asystolic arrest. 5. permanent pacemaker placement. 6. insulin-dependent diabetes. 7. hypertension. 8. hypercholesterolemia. 9. obesity. 10. renal insufficiency. 11. benign prostatic hypertrophy. , procedure: venous catheterization, not elsewhere classified continuous
