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: allergies: patient recorded as having no known allergies to drugs attending: chief complaint: chest pain major surgical or invasive procedure: coronary artery bypass grafting x 4 with left internal mammary artery to left anterior descending coronary; reverse saphenous vein single graft from aorta to ramus intermedius coronary artery; reverse saphenous vein single graft from aorta to first obtuse marginal coronary artery; as well as reverse saphenous vein single graft history of present illness: patient is a 78 yo male with history of coronary artery disease (mi in past) who states that for the past 2-3 weeks he has noted exertional angina requiring increased ntg sl use. for the past few weeks he has been using sl ntg daily when he would exert himself (wash the floor, run errands). on the day pta he had chest pain associated with diaphoresis and he took 24 sl ntg to relief waxing and chest discomfort - prompting his to present to hospital where he was started on iv ntg and transferred to nebh icu. his ck peaked at 445, ck mb 7.7 and troponin went from 0.47 to 0.32. he was then transferred to for cardiac cath. past medical history: coronary artery disease s/p myocardial infarction with known subtotal occlusion of rca hypertension hyperlipidemia diabetes mellitus peripheral vascular disease s/p left sfa stenting, right carotid endartarectomy, s/p right common femoral endarectomy benign prostatic hypertrophy social history: occupation: retired special armed services edentulous lives with wife : caucasian tobacco: remote use etoh: 1 drink/night family

three vessel disease. the lmca was heavily calcified with non-critical disease. the lad was calcified with moderate disease. the lcx had an ostial 99% stenosis. the rca was totally occluded proximally and filled via left to right collaterals. 2. resting hemodynamics revealed normal right and left sided filling pressures with rvedp of 9mmhg and lvedp of 17mmhg. there was mild pulmonary arterial systolic hypertension with pasp of 30mmhg. the cardiac index was preserved at 2.45 l/min/m2. the calculated fick cardiac output was 4.81 l/min. there was normal central arterial pressure with a systolic of 119mmhg, diastolic of 39mmhg, and mean of 69mmhg. 3. there was no significant gradient accross the aortic valve suggesting no appreciable aortic stenosis. 4. left ventriculography revealed no mitral regurgitation. the lvef was grossly normal with no regional wall motion abnormalities. 5. aortic fluoroscopy revealed a moderately calcified aortic arch. carotid u/s: right ica with no stenosis. left ica stenosis <40%. vein mapping: duplex evaluation performed of both lower extremity venous systems. right greater saphenous vein shows patency with diameters of 0.24 to 0.46 and the left greater saphenous vein, 0.21 to 0.61 chest ct: 1. pulmonary nodule (5-mm right) for which chest ct followup is recommended at six months guidelines. 2. dense atherosclerosis of the thoracic aorta and coronary arteries. echo: pre-bypass: the left atrium is mildly dilated. no spontaneous echo contrast or thrombus is seen in the body of the left atrium or left atrial appendage. no atrial septal defect is seen by 2d or color doppler. left ventricular wall thicknesses and cavity size are normal. there is moderate regional left ventricular systolic dysfunction with moderate anterior and antero-septal hypokinesis. the right ventricular cavity is mildly dilated with normal free wall contractility. there are simple atheroma in the ascending aorta. there are complex (>4mm) atheroma in the descending thoracic aorta. the aortic valve leaflets (3) appear structurally normal with good leaflet excursion. the aortic valve leaflets are mildly thickened. there is no aortic valve stenosis. no aortic regurgitation is seen. the mitral valve leaflets are moderately thickened. the mitral valve leaflets are myxomatous. there is mild mitral valve prolapse. moderate (2+) mitral regurgitation is seen. post cpb: 1. mildly improve global and focal lv systolci function. 2. mitral regurgitationis now mild. no other change 05:17am blood wbc-8.9 rbc-2.66* hgb-7.6* hct-23.5* mcv-88 mch-28.6

cath. cath revealed severe three vessel coronary artery disease. he was appropriately work-up for bypass surgery which also included carotid u/s, chest ct, echo and vein mapping. on he was brought to the operating room where he underwent a coronary artery bypass graft x 4. please see operative note for surgical details. following surgery he was transferred to the cvicu for invasive monitoring. he was extubated. he experienced atrial fibrillation with a rapid ventricular response, for which he was placed on amiodarone and converted back to sinus rhythm. his pressors were weaned and his chest tubes were removed. he was disoriented for the first couple of days post-operatively and then cleared. on post-operative day three his epicardial wires were removed and he was transferred to the surgical step down floor. by post-operative day four he had progressed well and was cleared for discharge to home by dr. . medications on admission: medication at home: amlodipine 5 mg daily,
