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: dyspnea on exertion major surgical or invasive procedure: - aortic valve replacement/coronary artery bypass grafting x2(lima-lad,free rima-pda) - mediastinal re-exploration with evacuation of blood clots. history of present illness: this 71 year old male with history of rheumatic heart disease as a child was hospitalized in with worsening shortness of breath, orthopnea and paroxysmal nocturnal dyspnea. he was found to be in congestive heart failure requiring diursesis and a heart murmur was detected exam. an echo revealed moderate to severe aortic stenosis and a cardiac catheterization revealed an ejection fraction of 25% with three vessel coronary disease and mild aortic stenosis. he was thus been referred for surgical management. past medical history: aortic stenosis coronary artery disease chronic heart failure cardiomyopathy (ef 25%) rheumatic heart disease age 14 coronary artery disease hypercholesterolemia osteoarthritis obesity skin ulcers ble/venous insufficiency phlebitis varicose veins s/p vein stripping social history: last dental exam: yearly. edentulous upper with native lower in poor repair. lives with: alone in . he has girlfriend. occupation: retired tobacco: quit pipe and cigars 2-3 months ago, prior cigarettes. 40+pyh. etoh: 3-6 beers /day family history: mother died of cad at 43 physical exam: height: 69" weight: 192 # general: wdwn in nad skin: warm dry intact no c/c heent: ncat perrla eomi sclera anicteric, op benign. lower teeth in poor repair. upper edentulous. neck: supple full rom no jvd chest: lungs clear bilaterally heart: rrr, iii/vi sem abdomen: soft non-distended non-tender bowel sounds + extremities: warm , well-perfused trace edema varicosities: bilateral gsv has been removed. incisions along gsv tract c/w stripping. lsv varicosed bilaterally. modified test slow flushing but positive neuro: grossly intact pulses: femoral right:2 left:2 dp right:trace left:trace pt :trace left:trace radial right:2 left:2 carotid bruit bilateral transmitted vs. bruit pertinent results: echo: this is a limited study for emergency mediastinal exploration 24 hrs. after avr/cabg. the patient is on high dose pressors, no inotropes. there is a pericardial collection measuring 1.5 cm near the anterior wall. there no evidence of right-sided collapse. this corresponded clinically to a large amount of clot found after the chest was opened. there was little ongoing bleeding. there is 1+ mr. fxn is mildly depressed. there is a well-seated prosthetic aortic valve with a residual peak gradient of 23 and mean of 11 mmhg. no leak and no ai. aorta intact. cxr: small bilateral pleural effusions and atelectasis. no acute cardiopulmonary process. 05:00am blood wbc-8.5 rbc-3.77* hgb-11.2* hct-32.0* mcv-85 mch-29.8 mchc-35.2* rdw-14.2 plt ct-176 06:10am blood wbc-7.6 rbc-3.59* hgb-10.9* hct-30.8* mcv-86 mch-30.2 mchc-35.2* rdw-14.5 plt ct-127*# 06:55am blood urean-15 creat-0.8 na-136 k-3.9 cl-102 05:00am blood urean-15 creat-0.8 na-141 k-3.8 cl-106 brief hospital course: mr. was admitted to the on for surgical management of his aortic valve and coronary artery disease. he was taken to the operating room where he underwent coronary artery bypass grafting to two vessels and replacement of his aortic valve. please see operative note for details. postoperatively he was taken to the intensive care unit for monitoring. on postoperative day one, high output from his chest tube was noted. he was returned to the operating room where he underwent a re-exploration for bleeding with evacuation of clot. no focal bleeding was found and hemostasis was achieved. he was returned to the intensive care unit in stable condition. he was later weaned form sedation and extubated without issue. gentle diuresis was initiated. beta blockade, a statin and aspirin were resumed. he developed atrial fibrillation and was started on amiodarone for this. he then developed junctional rhythm and amiodarone was discontinued. sinus rhythm ensued and beta blockade was titrated as tolerated. on postoperative day two, he was transferred to the step down unit for further recovery. chest tubes and pacing wires were removed per protocol. the physical therapy service was consulted for assistance with his postoperative strength and mobility. blood pressure medications were titrated for better control. on post-op day seven he was potentially going to be discharged but spiked a temperature of 100.1 . he remained stable, the temperature remained down and he continued to make good progress and was cleared for discharge to newbridge on the . all follow-up appointments were made or advised. he did have some skin tearing to the right of the mid sternal wound, which was dry and had resolved erythema at discharge when seen with dr. . medications on admission: furosemide -
