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 a 71-year-old man transferred from hospital for cardiac catheterization. the patient states he had chest pain while out walking his dog on sunday afternoon, relieved with rest and nitroglycerin. in the emergency room his enzymes were elevated with a ck of 508, ck mb of 2.9, troponin 0.5. he was transferred here for catheterization. he had a stress echocardiogram two weeks ago that showed aortic regurgitation. the patient denied chest pain, shortness of breath, dyspnea on exertion, fevers, sweats, chills, diabetes mellitus, cerebrovascular disease, cancer, or claudications. past medical history: 1. coronary artery disease. 2. valvular heart disease. 3. benign prostatic hypertrophy. 4. hypertension. 5. chronic obstructive pulmonary disease. 6. asthma. 7. ulcerative colitis. 8. enlarged prostate. 9. chronic renal insufficiency. past surgical history: 1. partial colectomy. 2. appendectomy. medications at home: 1. coreg 12.5 twice. 2. norvasc 5 mg b.i.d. 3. zestril 20 mg b.i.d. 4. proscar 5 mg q.d. 5. lasix 40 mg q.d. 6. advair 150 one puff b.i.d. 7. colazal 750 mg three tablets t.i.d. 8. nitroglycerin paste 1 inch q. 6. social history: no tobacco use. cardiac catheterization showed an ejection fraction of 41%, aortic regurgitation 3+, lm 60, lad normal, om 80, circumflex and rca normal, left ventricular end-diastolic pressure 22, pa 37/11. physical examination: temperature 97.4, heart rate 70 in sinus rhythm, blood pressure 190/99, respiratory rate 20, o2 saturations 97% on room air. general: the patient was alert and oriented x 3, moved all extremities, followed commands. heent: pupils were equal, round, and reactive to light. extraocular movements intact. anicteric, noninjected sclerae. neck: supple, no lymphadenopathy, no jugular venous distension, no bruits. mucous membranes were moist, no erythema or exudate in the oropharynx. lungs: clear to auscultation bilaterally. cardiac: regular rate and rhythm. abdomen: soft, nontender, nondistended, no hepatosplenomegaly. extremities: warm and well perfused with no cyanosis, clubbing or edema. hospital course: the patient was admitted to on and taken to the operating room where a three-vessel coronary artery bypass grafting was performed as well as an aortic valve replacement. postoperatively the patient was transferred to the cardiothoracic surgical intensive care unit. he had mediastinal and chest tubes in place, pacing wires in place. he received prophylactic vancomycin doses x 4. on his first postoperative day the patient experienced ventricular tachycardia x 20 beats. he required milrinone and levophed drips. at the appropriate times the patient's drips were stopped. he was started on beta blockade. he was also started on amiodarone when his ventricular tachycardia recurred. when his creatinine fell he was started on lasix. he was also started on amlodipine. once the patient's hypertensive medications were regulated to appropriately control his blood pressure the patient was transferred to the regular cardiothoracic surgery floor where he thrived. he has been visited by physical therapy who has worked with him extensively and is comfortable with him going to a rehabilitation facility. therefore today, , he is being discharged to rehabilitation. follow up: the patient is to follow up with dr. in six weeks, dr. in one to two weeks, and cardiology in two to three weeks. recommendations: he should observe a heart healthy diet. he may shower although he should not take baths. the patient should avoid strenuous activity and should not drive while on pain medications. discharge medications: 1. amiodarone 400 mg q.d. 2. advair 2 puffs b.i.d. 3. hydralazine 10 mg iv q. 3 p.r.n. systolic blood pressure greater than 160. 4. amlodipine 10 mg q.d. p.o. 5. hydralazine 25 mg q. 6 p.o. 6. albuterol 1-2 puffs q. 6 p.r.n. 7. benadryl 25 mg p.o. q.h.s. p.r.n. sleep 8. milk of magnesia 30 mg
