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 72-year-old male who was admitted to the hospital with angina pectoris. he has a past medical history of myocardial infarction times two, once in and once in . he has a recent exercise tolerance test that was positive. an echocardiogram obtained on , demonstrated an ejection fraction equal to 45%. a cardiac catheterization performed on , revealed severe obstruction to the left anterior descending artery, diagonal, circumflex, and right coronary arteries. ventricular function was moderately depressed with an ejection fraction equal to approximately 40%. the patient was subsequently referred to cardiothoracic surgery to assess him for coronary artery bypass graft. medications on admission: aspirin 325 mg p.o. q.d., imdur 30 mg p.o. b.i.d., toprol-xl 50 mg p.o. q.d., prevacid 30 mg p.o. q.d., cardura 6 mg p.o. q.d., atrovent meter-dosed inhaler 2 puffs b.i.d. p.r.n., hydrocodone 2 pills t.i.d. for knee pain. physical examination on admission: the patient was in no acute distress. his neck was supple. there were no bruits or masses. his lungs were clear to auscultation bilaterally. he had a regular rate and rhythm. there were no murmur, rubs or gallops. his abdomen was soft, nontender, and nondistended. his extremities were warm and well perfused. there was no edema. hospital course: the patient was admitted on and underwent an uncomplicated coronary artery bypass graft times three with left internal mammary artery to the left anterior descending artery, reverse saphenous vein graft to the circumflex marginal, reverse saphenous vein graft to the right posterior descending artery. the patient tolerated the procedure well and was transported to the cardiothoracic surgery intensive care unit intubated and in stable condition. the patient was extubated overnight. on postoperative day one, he was noted to have electrocardiogram changes concerning for ischemia. he was therefore started on a rule out myocardial infarction protocol. he started lasix, aspirin, and lopressor. his nitroglycerin drip was weaned. the subsequent cardiac enzymes all came back within normal limits. therefore, he ruled out for a myocardial infarction. on postoperative day two, his foley was discontinued. his lopressor was increased, and he was started on an ace inhibitor. he was tolerating p.o. intake. his pacing wires were discontinued. his chest tube put out 345 cc over the prior day, and it was decided to keep the chest tube. as the patient deemed hemodynamically stable and ambulating, the decision was made to transfer the patient to the floor. unfortunately, there were no beds available, and the patient stayed overnight in the unit. on postoperative day three, the patient went into a rapid atrial fibrillation with hypotension. lopressor at 20 mg intravenously was given with no change in heart rate. he remained hypotensive. he was given an amiodarone bolus and an amiodarone drip was started. he remained in atrial fibrillation throughout the day with a rate in the 110s to 140s. it was decided that the patient should stay overnight in the unit to monitor his heart rate and blood pressure. on postoperative day four, the patient remained in atrial fibrillation. he was however hemodynamically stable. his amiodarone drip was converted to p.o. he was started on coumadin. as the patient was hemodynamically stable, he was transferred to the floor. on postoperative day five, the patient noted substernal chest pain somewhat similar to his anginal pain. he also said that he felt diaphoretic. a 12-lead electrocardiogram was performed which demonstrated no evidence of acute ischemic changes compared to his prior electrocardiograms. nonetheless, his presentation was concerning, and a cardiology consultation was obtained. their feelings were that the pain was most likely not of cardiac origin, but that cardiac enzymes should be cycled nonetheless. this was done, and the levels were all negative. on postoperative day six, the patient had no complaints of chest pain. on postoperative day seven, the patient was tolerating p.o., was pain free, and was able to walk 500 feet without hemodynamic instability. his central venous line was discontinued. on postoperative day eight, the patient had remained afebrile with stable hemodynamics, tolerating p.o., and making adequate amounts of urine. physical therapy had assessed the patient, and he was able to climb a flight of stairs with no hemodynamic instability. it was thus decided that he was stable enough to go home without services, and he was subsequently discharged on (on postoperative day eight) in stable and good condition. physical examination on discharge: his temperature was 98.4, heart rate 79, blood pressure 92/54, respiratory rate of 18, oxygen saturation of 93% on room air. the patient was in no acute distress, alert and oriented. his lungs were clear. his sternum was stable, clean, dry, and intact. he had a regular rate and rhythm. he had a soft and nontender abdomen. his extremities were warm and well perfused with incisions clean, dry, and intact. medications on discharge: 1. lopressor 75 mg p.o. b.i.d. 2. lasix 20 mg p.o. b.i.d. times one week. 3. potassium chloride 20 meq p.o. b.i.d. times one week. 4. colace 100 mg p.o. b.i.d. 5. aspirin 81 mg p.o. q.d. 6. motrin 400 mg p.o. t.i.d. p.r.n. 7. protonix 40 mg p.o. q.d. 8. cardura 6 mg p.o. q.d. 9. amiodarone 400 mg p.o. t.i.d. times three days; then 400 mg p.o. b.i.d. times seven days; then 400 mg p.o. q.d. 10. percocet one to two tablets p.o. q.3-4h. p.r.n. for pain. discharge diagnoses: 1. coronary artery disease. 2. status post coronary artery bypass graft times three. condition at discharge: condition on discharge was stable. discharge status: to home. discharge instructions: the patient was instructed to follow up with dr. in one week and with his primary care physician, . one to two weeks. , m.d. dictated by: medquist36
