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: no known allergies / adverse drug reactions attending: chief complaint: mild dyspnea on exertion major surgical or invasive procedure: coronary artery bypass grafting x4 (left internal mammary artery grafted to the left anterior descending artery/ saphenous vein grafted to diagnal/ramus/right coronary artery- history of present illness: 72 year old male who had some mild complaints of dyspnea on exertion. denies chest pain, palpitations or dizziness. had a cardiac cath done several years ago which revealed moderate lad and rca disease. has been medically managed and then underwent a stress test which was positive for ischemia. therefore, had a cardiac cath which revealed severe three vessel coronary artery diseease and was referred for surgical intervention past medical history: coronary artery disease s/p cabg post operative atrial fibrillation secondary: hypertension hyperlipidemia hypothyroidism borderline diabetes mellitus possible skin cancer left cheek tremors or several years social history: lives with: wife occupation: retired cigarettes: smoked yes last cigarette ? hx: 1.5ppd x 40+ yrs other tobacco use: denies etoh: < 1 drink/week drinks/week >8 drinks/week 3 scotch/night illicit drug use: denies family history: non-contributory physical exam: pulse: 54 resp: 18 o2 sat: 98% b/p right: - left: 128/79 height: 70" weight: 232" general: well-developed obese male in no acute distress skin: dry intact heent: perrla eomi exopthalamus neck: supple full rom chest: lungs clear bilaterally heart: rrr irregular murmur grade ______ abdomen: soft non-distended non-tender bowel sounds + extremities: warm , well-perfused edema _____ varicosities: bilat varicosities, large on right leg neuro: grossly intact pulses: femoral right: 2+ left: 2+ dp right: 2+ left: 2+ pt : 2+ left: 2+ radial right: faint left: 2+ carotid bruit right: - left: - pertinent results: intra-op tee echocardiography report conclusions pre-cpb: the left atrium is markedly dilated. no atrial septal defect is seen by 2d or color doppler. the left ventricular cavity is moderately dilated. overall left ventricular systolic function is mildly depressed. estimated lvef= 45%. the right ventricular cavity is mildly dilated with borderline normal free wall function. the descending thoracic aorta is mildly dilated. there are complex (>4mm) atheroma in the descending thoracic aorta. no thoracic aortic dissection is seen. the aortic valve leaflets (3) appear structurally normal with good leaflet excursion and no aortic stenosis. there are filamentous strands on the aortic leaflets consistent with lambl's excresences (normal variant). trace eccentric aortic regurgitation is seen from the commissure between the left and the non-coronary cusps. the mitral valve leaflets are mildly thickened. mild (1+) mitral regurgitation is seen. post-cpb: after initial separation from bypass, the patient is on a low dose norepinephrine infusion. images from 15 minutes after separation shows improved biventricular function, estimated lvef=50%. the rv systolic function appears normal. mr remains mild. other valvular function are unchanged. the co is calculated to be 5.8l/min. upon closure of sternum, the patient requires more than the normal escalation of vasopressors and does not respond to fluid bolus. reinspection of echo images at this time shows new notable lv inferior wall hypokinesis as well as rv free wall hypokinesis. surgeon immediately notified. over the next 10 minutes, the rv free wall becomes severely hypokinetic, with sparing of the basal segment. the lv inferior and inferoseptal segments also appears severely hypokinetic. the sternum is reopened and vein graft to rca is messaged with near immediately improvement in the rv free wall and lv inferior wall contractility on echo images. when the sternum is closed again 30 minutes later, the same wall motion abnormalities are again noted. surgeons aware and believe this not to be due to graft kinking. low dose epinephrine started with mild improvement of rv free wall and lv inferior wall contractility. final chest closed estimated lvef=40%. there is no evidence of aortic dissection. cxr findings: the right ij line tip is in the distal svc. mediastinal clips and sternal wires are unchanged. there continues to be moderate cardiomegaly. there is improved aeration in the left lower lobe with some residual volume loss/effusion. there is also probable small right effusion. overall, the appearance of the lungs is improved compared to the study from the prior day. .

operating room and underwent coronary artery bypass graft surgery. see operative report for further details. he tolerated the procedure well and was transferred to the cvicu for invasive monitoring. he was weaned from sedation, awoke neurologically intact and was extubated that evening. he was progressively weaned off pressors and inotropes. on post operative day one he was started on betablockers and diuretics. he continued to do well and was transferred to the post operative floor. earlier the morning of post operative day two he went into rapid atrial fibrillation, was treated with beta-blockers and additionally amiodarone which he converted back to sinus rhythm after multiple hours. chest tubes were removed on post operative day three and epicardial wires on post operative day four. physical therapy worked with him on strength and mobility. he continued with burst of atrial fibrillation, lopressor was titrated and he continued on oral amiodarone. coumadin was initiated due to ongoing episodes of atrial fibrillation. he was noted for sternal drainage placed on antibiotics. on post operative day seven he had supratherapuetic inr and received vitamin k and fresh frozen plasma, and additionally had echocardiogram which ruled out pericardial effusion. he remained in the hospital due to ongoing episodes of atrial fibrillation. rate control was achieved and the patient was discharged home on pod 12. his pcp will manage inr/coumadin dosing. medications on admission: atenolol 50mg daily nifedical xl 30mg daily lasix 40mg daily lipitor 40mg daily levothyroxine 125mg
