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 65 -year-old gentleman with a progressive dyspnea on exertion and paroxysmal nocturnal dyspnea over the past two months. he had a positive exercise tolerance test with some atrial and ventricular arrhythmias noted and underwent cardiac catheterization in which revealed a left ventricular ejection fraction of 18%, three vessel coronary artery disease, and severe global hypokinesis and he was referred to cardiothoracic surgery service for coronary artery bypass grafting. past medical history: 1. non-insulin-dependent diabetes mellitus. 2. hyperlipidemia. 3. recent congestive heart failure. 4. status post bilateral cataract extraction. 5. status post hand surgery many years ago. 6. status post ankle injury. 7. transient vertigo attributed to an inner ear infection many years ago. preoperative medications: univasc 15 mg po q day, lasix 20 mg po q day, aspirin 325 mg po q day, glyburide 10 mg po bid, glucophage 1,000 mg po bid, lipitor 10 mg po q day, and viagra 100 mg prn. allergies: no known drug allergies. physical examination: physical examination on admission to the hospital was unremarkable. hospital course: the patient was taken to the operating room on , with dr. , where he underwent coronary artery bypass graft times four with a left internal mammary artery to the left anterior descending, saphenous vein graft to the obtuse marginal artery, saphenous vein graft to the posterior descending artery, and saphenous vein graft to the diagonal. postoperatively the patient was transported from the operating room to the cardiac surgery recovery unit on iv drips of propofol, milrinone, and lidocaine. he was in normal sinus rhythm at that time. the patient was placed on lidocaine for frequent ventricular arrhythmias. the milrinone was weaned off by the following morning and late in the day on postoperative day one the lidocaine was discontinued, as was the iv neo-synephrine which had been started for some transient postoperative hypotension. the patient was transferred to the telemetry floor on postoperative day one. an electrophysiology consultation was obtained due to frequent ventricular arrhythmias in the light of a low ejection fraction. it was their recommendation to begin a beta blocker when the patient was hemodynamically stable and to study him. over the next few days on the telemetry floor, the patient remained hemodynamically stable, continued to have frequent premature ventricular contractions, was progressing with cardiac rehabilitation, had been started on low dose beta blocker and begun on diuretics. his chest tubes had been discontinued. the patient was taken to the electrophysiology lab on , where he underwent placement of a dual chamber implantable cardioverter defibrillator. the patient tolerated the procedure well and has remained on the cardiothoracic / telemetry floor since the placement of the device. he has remained hemodynamically stable and he is ready to be discharged home today, on , postoperative day seven. discharge condition: stable. discharge physical examination: temperature 98.6 f, pulse 75 and normal sinus rhythm, blood pressure 110/80. his weight today is 106.2 kg, 1.0 kg above his preoperative weight of 107.2 kg. his room air oxygen saturation is 98%. neurologically the patient is intact. pulmonary examination is unremarkable. his lungs are clear to auscultation bilaterally. his coronary examination is regular rate and rhythm. his sternum is stable. his incision is clean, dry, and intact and his right leg incision is also clean, dry, and intact with no erythema or drainage. laboratory data: his most recent chest x-ray is from , which revealed small bilateral pleural effusions and left lower lobe atelectasis. most recent laboratory values are from , which revealed a white blood cell count of 10,100, hematocrit of 24.8, a platelet count of 379,000. urinalysis on revealed 0 to 2 white blood cells, and few bacteria. other laboratory values from , are a sodium of 138, potassium 4.9, chloride 105, co2 27, bun 24, creatinine 1.2, glucose 110. discharge medications: lasix 20 mg po bid times one week, potassium chloride 20 meq po bid times one week, colace 100 mg po bid, enteric coated aspirin 325 mg po q day, glucophage 1,000 mg po bid, glyburide 10 mg po bid, captopril 12.5 mg po q eight hours, lipitor 10 mg po q hs, lopressor 12.5 mg po bid, amiodarone 200 mg po tid times one week, then amiodarone 400 mg po q day times one month, then amiodarone 200 mg po q day, ibuprofen 400 mg po q six hours prn, percocet 5/325 one tablet po q four hours prn pain, and ciprofloxacin 500 mg one tablet po bid times five days for the urinary tract infection. follow up: the patient is to follow up in the device clinic here at - on the , seventh floor, cardiology department, on , at 11 o'clock in the morning. the telephone number there is . he is to follow up with dr. next week. his office has been contact. and he is to follow up with dr. in one month for postoperative wound check. discharge status: stable. discharge diagnoses: 1. coronary artery disease, status post coronary artery bypass graft. 2. severe left ventricular dysfunction. 3. frequent ventricular arrhythmias, status post automatic implantable cardioverter - defibrillator placement. , m.d. dictated by: medquist36 procedure: (aorto)coronary bypass of three coronary arteries single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery implantation or replacement of automatic cardioverter/defibrillator, total system [aicd] diagnoses: coronary atherosclerosis of native coronary artery unspecified pleural effusion congestive heart failure, unspecified diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled other chronic pulmonary heart diseases atrial flutter pulmonary collapse paroxysmal ventricular tachycardia
