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: terazosin / atenolol / univasc / clonidine attending: chief complaint: congestive heart failure major surgical or invasive procedure: coronary artery bypass graft x 4 (left internal mammary artery to left anterior descending, saphenous vein graft to diag, saphenous vein graft to obtuse marginal, saphenous vein graft to posterior descending artery), aortic valve replacement (23mm st. tissue valve) history of present illness: this 87 year old white male was recently found to be in atrial fibrillation and found to have coronary artery disease and aortic stenosis during his workup. he had been scheduled for surgical intervention, but was hospitalized at or dyspnea. he was treated medically and referrred for earlier intervention due to his symptoms. he was cleared by his neurologist, being stable on medications with his last seizure in , . past medical history: coronary artery disease aortic stenosis seizure disorder h/o atrial fribrillation hypertension dyslipidemia gastroesophageal reflux disease gout s/p hernia repair social history: denies tobacco rare etoh use. family history: non-contributory physical exam: admission: vss, afebrile. 136/86 bilat. neuro:grossly intact heent: negative. edentulous cor: 3/6 sem radiating to neck lungs: clear exts:trace bilateral edema pertinent results: chest ct: severe coronary artery calcifications. extensive calcification of the aortic and mitral valves. moderate atherosclerotic calcification of the thoracic aorta. small bilateral pleural effusions and mild dependent atelectasis of the lower lobes. carotid cnis: 1. no significant ica stenosis on either side. 2. antegrade flow in both vertebral arteries. echo: pre-bypass: the left atrium is dilated. mild spontaneous echo contrast is seen in the body of the left atrium. no mass/thrombus is seen in the left atrium or left atrial appendage. mild spontaneous echo contrast is present in the left atrial appendage. right ventricular chamber size and free wall motion are normal. there are simple atheroma in the aortic arch. the aortic valve leaflets are severely thickened/deformed. there is moderate to severe aortic valve stenosis (area 0.8-1.0cm2). mild to moderate (+) aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. mild (1+) mitral regurgitation is seen. there is no pericardial effusion. dr. was notified in person of the results on mr at before surgical incision. post-bypass: preserved biventricular systolic function. lvef 55%. the aortic bioprosthesis is insitu, stable and functioning well and peak and mean gradients of 16 and 6mm of hg respectively. intact thoracic aorta. trivial mr> 01:20pm blood wbc-20.8*# rbc-3.83* hgb-10.8*# hct-32.7* mcv-86 mch-28.3 mchc-33.1

grafts were performed. see operative note for details. he weaned from bypass in stable condition on neo synephrine and propofol. following transfer to the icu he remained stable, weaned from pressors and was extubated the night of surgery. wires and tubes were d/c'd per cardiac surgery protocol. pt receiving ace inhibitor, statin and betablocker. has been in rate controlled afib. progressed well and was evaluated by physical therapy and thought to benefit from rehab stay prior to returning to home. the patient was discharged in good condition to rehab on pod 5. all follow up instructions were
