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: mr. is a 71 year old gentleman with a history of stable mild exertional angina since the early . he has been medically managed through the years and has been tolerating management well. he describes his symptoms as mild pressure across the chest which resolved with rest. he walks approximately four miles each day as well. on , he had a stress test and developed angina after four minutes, showing depressions in leads v4 through v6. follow-up imaging revealed a mild to moderate sized reversible anteroseptal and antero-apical defect. his ejection fraction was noted to be 48% at the time. subsequently he underwent cardiac catheterization at the on , which revealed left ventricular ejection fraction of 55% with a mitral regurgitation. he was also shown to have 80% stenosis of the proximal right coronary artery, 100% stenosis of the distal right coronary artery, 50% stenosis of the left main artery, 100% stenosis of the mid left anterior descending, 80% stenosis of the proximal circumflex. he was admitted on the same day for a coronary artery bypass graft. past medical history: 1. coronary artery disease times 30 years. 2. hypertension. 3. hypercholesterolemia. 4. noninsulin dependent diabetes mellitus. 5. moderate chronic obstructive pulmonary disease. 6. status post repair of triple aneurysm in . 7. status post suprapubic prostatectomy. medications: 1. aspirin 325 mg p.o. q. day. 2. diltiazem 180 mg p.o. q. day. 3. lipitor 10 mg p.o. q. h.s. 4. glucotrol xl 2.5 mg p.o. q. day. 5. lisinopril 5 mg p.o. q. day. allergies: no known drug allergies. family history: his family history is unremarkable except for a small history of cerebrovascular accidents. social history: he currently lives at home with his wife. had admitted to smoking heavily with a 90 pack year smoking history, but quit 14 years prior. he rarely drinks any alcohol. physical examination: on physical examination when he was admitted, he was afebrile with stable vital signs. he had full extraocular movements and his pupils were equal and reactive and he had no palpable cervical nodes. his neck was supple with no lymphadenopathy. his carotids were two plus bilaterally with no bruits. his lungs were clear to auscultation. he had an irregular pulse and normal heart sounds with no murmurs. his abdominal examination was benign. his abdomen was nontender to palpation with normal bowel sounds and no palpable masses. he had good peripheral pulses with warm extremities. he had no peripheral edema. hospital course: he was admitted to the hospital on , for a coronary artery bypass graft. on , he was taken to the operating room for a coronary artery bypass graft times four. he had his left internal mammary artery grafted to the left anterior descending; saphenous vein graft to the diagonal and obtuse marginal, and the saphenous vein graft to the patent ductus arteriosus. he was placed under general anesthesia and intubated for the procedure. he tolerated the procedure well and recovered without complications. postoperatively he did well. he remained neurologically intact and his neo-synephrine was weaned. on postoperative day four, he experienced an episode of atrial fibrillation. he was started on an amiodarone drip after a bolus and then converted to 400 mg p.o. twice a day. he converted back to sinus rhythm. he experienced some agitation while in the intensive care unit and became suddenly confused and belligerent. he became paranoid and refused certain treatments. psychiatry was called for consultation and the diagnosis of postoperative delirium was made. he was started on haldol 2 mg p.o. three times a day p.r.n. and he continued to improve. on postoperative day six, he was started on lopressor 25 mg p.o. twice a day. on postoperative day seven, he was noted to have some subcutaneous emphysema and air leak in the mediastinal tube was noted. the right chest tube was removed on postoperative day eight but he persisted in having an air leak. ultimately, he had three chest tubes placed, one mediastinal and two additional chest tubes. he continued to have an air leak. cardiology was consulted for his postoperative paroxysmal atrial fibrillation in which he developed significant pauses while on metoprolol, amiodarone and haldol. they felt that his intrinsic sinus node function was okay. they suggested resuming his metoprolol 25 mg p.o. twice a day, holding the amiodarone, and then anti-coagulating him if atrial fibrillation persisted. if this was required, they would follow-up after the chest tubes were removed for replacement. he continued to have some episodes of supraventricular tachycardia which the electrophysiology fellow thought was atrial flutter. during one of these episodes, a 12 lead ekg was obtained which was suggestive of atrial flutter. the plan from cardiology was then to ablate him once the chest tubes were removed. he remained in the unit on postoperative day 15 with a persistent leak. both chest tubes and his mediastinal tubes were clamped on postoperative day 15 and then one chest tube was removed on hospital day 15. his air leak has gradually been decreasing as well as the subcutaneous emphysema. on postoperative day 16, he was transferred to the floor. he was doing well with stable vital signs and in sinus rhythm. his remaining chest tube on the right was removed and his mediastinal tube was converted to a heimlich valve with a foley bag attachment. that evening, he had a short period of atrial fibrillation in which he spontaneously converted back to sinus rhythm. he has currently been more than 24 hours without an arrhythmia. he is stable with normal vital signs. he has been ambulating with assistance and tolerating his p.o. intake well. he has had bowel movements. his air leak has continuously been improving. he is finally stable for discharge home with follow-up physical therapy. he is to follow-up with dr. in four weeks. he has been told to follow-up with his primary care physician and his cardiologist in one to two weeks. he has been advised not to lift weights greater than ten pounds for three months. he was advised not to drive for one month or while on pain medications. discharge medications: 1. metoprolol 12.5 mg p.o. twice a day. 2. lasix 20 mg p.o. twice a day times seven days. 3. potassium chloride 20 meq p.o. twice a day times seven days. 4. colace 100 mg p.o. twice a day. 5. enteric-coated aspirin 325 mg p.o. q. day. 6. percocet 5/325 mg one to two tablets p.o. q. four to six hours for pain p.r.n. 7. glipizide 2.5 mg, one tablet p.o. q. day. 8. lipitor 10 mg tablet p.o. q. day. 9. haldol 1 mg p.o. three times a day p.r.n. , 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 angiocardiography of left heart structures left heart cardiac catheterization coronary arteriography using a single catheter catheter based invasive electrophysiologic testing excision or destruction of other lesion or tissue of heart, endovascular approach diagnoses: coronary atherosclerosis of native coronary artery pure hypercholesterolemia unspecified essential hypertension chronic airway obstruction, not elsewhere classified atrial fibrillation atrial flutter other and unspecified angina pectoris surgical operation with anastomosis, bypass, or graft, with natural or artificial tissues used as implant causing abnormal patient reaction, or later complication, without mention of misadventure at time of operation emphysema (subcutaneous) (surgical) resulting from procedure
