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: the patient is an 84-year-old male with a history of hypertension, hypercholesterolemia, remote tobacco history, coronary artery disease (status post myocardial infarction times two), recent unstable angina with catheterization showing 3-vessel disease who was transferred from an outside hospital following and episode of congestive heart failure. the patient was reported to be an active volunteer at the outside hospital until one and a half years ago when he reportedly had a decline in his exercise tolerance secondary to a myocardial infarction and arthritis. the patient complained of chest pain which was nonradiating upon waking up in the morning, relieved by nitroglycerin recently. these complaints were worked up by cardiac catheterization on which showed 3-vessel disease. the patient was advised to have a coronary artery bypass graft. the patient was in the middle of undergoing a workup for the coronary artery bypass graft (which included evaluation of his renal insufficiency); when, over the period from through , the patient woke up on three successive nights with shortness of breath without any chest pain, diaphoresis, or other symptoms. the first two episodes lasted a few minutes but resolved spontaneously. the third episode apparently did not resolve for greater than 30 minutes; at which point the patient called an ambulance was taken to the outside hospital where he was found to be in congestive heart failure. he was admitted there and diuresed over a period of days. the patient was noted to hypertensive on admission at the outside hospital with a troponin leak (peak 1.6). on evaluation, the patient was found to have left renal artery stenosis. following resolution of the patient's congestive heart failure, he was transferred to the for further management. past medical history: 1. peripheral vascular disease. 2. arthritis of left knee and hip. 3. status post abdominal aortic aneurysm repair. 4. hypertension. 5. glaucoma. 6. hypercholesterolemia. 7. prostate cancer; status post transurethral resection of prostate times two. 8. right shoulder repair. 9. back surgery for ruptured disk. 10. chronic renal insufficiency. 11. coronary artery disease; status post myocardial infarction times two. 12. cerebellar dysfunction. 13. right iliac artery stenosis, status post bypass in . 14. aortic sclerosis. medications on admission: 1. norvasc 5 mg p.o. b.i.d. 2. capoten 25 mg p.o. b.i.d. 3. dyazide 1 mg p.o. q.d. 4. lasix 20 mg p.o. q.o.d. 5. atenolol 25 mg p.o. q.d. 6. imdur 90 mg p.o. b.i.d.

(with a plan to taper the amiodarone). by postoperative day six, the patient was doing well on the floor with his pain well controlled. he continued to switch back and forth from a normal sinus rhythm to atrial fibrillation. the patient was started on coumadin therapy on the day following the placement of his pacemaker. he was maintained on a heparin drip with a plan to discontinue the drip when the patient was therapeutic on his coumadin. by postoperative day seven, the patient's pacemaker had been confirmed to be working well. arrangements were made for his discharge to a rehabilitation facility following discharge. the patient had an episode of urinary retention while in the cardiothoracic surgery recovery unit requiring a urology consultation. although the initial recommendation was for the patient to be discharged with a foley catheter and a leg bag, the patient was subsequently able to void on his own without a catheter. the patient will need to follow up with his urologist following discharge. condition at discharge: condition on discharge was stable. medications on discharge: 1. coumadin (dosed daily). 2. amiodarone 400 mg p.o. b.i.d. times two weeks; with a plan to wean to amiodarone 400 mg p.o. q.d. for one month; and then amiodarone 200 mg p.o. q.d. as maintenance. 3. tamsulosin 0.4 mg p.o. q.h.s. 4. hydralazine 50 mg p.o. q.6h. 5. protonix 40 mg p.o. q.d. 6. atorvastatin 10 mg p.o. q.h.s. 7. amlodipine 10 mg p.o. b.i.d. 8. timolol 0.5% one drop both eyes b.i.d. 9. latanoprost 0.005% ophthalmic solution one drop both eyes q.h.s. 10. pilocarpine 4% one drop left eye b.i.d. 11. oxazepam 15 mg to 30 mg p.o. q.h.s. 12. dulcolax 10 mg p.r. q.d. as needed. 13. milk of magnesia 30 ml p.o. q.h.s. as needed. 14. tylenol 650 mg p.o. as needed. 15. percocet one to two tablets p.o. q.4-6h. as needed. 16. enteric-coated aspirin 325 mg p.o. q.d. 17. colace 100 mg p.o. b.i.d. 18. lasix 40 mg p.o. b.i.d. (until the patient at baseline weight). 19. metoprolol 25 mg p.o. b.i.d. discharge followup: 1. the patient was to follow up with dr. one month following discharge. 2. the patient was to follow up with the electrophysiology service at 10 a.m. on . he was to call for an appointment. 3. the patient was to follow up with his primary care physician one to two weeks following discharge. 4. the patient's coumadin dosing will need to be monitored at the rehabilitation facility until his subsequent discharge to home where his coumadin dosing will need to be monitored by either his primary care physician or his cardiologist. discharge diagnoses: coronary artery disease requiring coronary artery bypass graft. , 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 initial insertion of dual-chamber device initial insertion of transvenous leads [electrodes] into atrium and ventricle atrial cardioversion pulmonary artery wedge monitoring monitoring of cardiac output by other technique diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome congestive heart failure, unspecified cardiac complications, not elsewhere classified atrial fibrillation hypertensive chronic kidney disease, unspecified, with chronic kidney disease stage v or end stage renal disease atherosclerosis of renal artery retention of urine, unspecified sinoatrial node dysfunction
