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: zithromax / lisinopril / simvastatin attending: chief complaint: shortness of breath/chest tightness major surgical or invasive procedure: redo sternotomy/ aortic valve replacement(27-mm st. ) history of present illness: this 76 year old male underwent coronary artery bypass grafting in . he called his cardiologist few days ago and stated that he was having increased shortness of breath. a tte revealed severe aortic stenosis and he was referred for cardiac catheterization to evaluate aortic stenosis and for current coronary status. his catheterization confirmed severe aortic stenosis and 70% lesion of his lad. past medical history: aortic stenosis coronary artery disease s/p coronary artery bpass grafts s/p redo sternotomy, aortic valve replacement/coronary

drink alcohol. family history: positive for heart disease. everything else is negative. physical exam: pulse: resp:18 o2 sat: 98% ra b/p right: 109/79 left: 101/69 height:5ft 11" weight:222lbs five

mild spontaneous echo contrast is seen in the body of the left atrium. mild spontaneous echo contrast is present in the left atrial appendage. the left atrial appendage emptying velocity is depressed (<0.2m/s). no thrombus is seen in the left atrial appendage. no atrial septal defect is seen by 2d or color doppler. there is mild symmetric left ventricular hypertrophy. the left ventricular cavity size is normal. there is mild regional left ventricular systolic dysfunction with focalities in the mid and apical lateral wall.. overall left ventricular systolic function is mildly depressed (lvef=45 %). right ventricular chamber size and free wall motion are normal. there are focal calcifications in the aortic arch. there are simple atheroma in the descending thoracic aorta. there is critical aortic valve stenosis (valve area <0.8cm2). trace aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. an eccentric, posteriorly directed jet of moderate (2+) mitral regurgitation is seen. there is no pericardial effusion. dr. was notified in person of the results before surgical incision. post_bypass: normal rv systolic function. lvef 45%. no new regional wall motion abnormalities. the aortic bioprosthesis is stable and functioning well with a residual mean gradient of 2 mm of hg mild mr. other valvular findings. intact thoracic aorta.. 05:39am blood

the operating room where he underwent redo sternotomy with replacement of his aortic valve with a 27-mm st. tissue valve. please see operative note for details. postoperatively he was taken to the intensive care unit for monitoring. on postoperative day one, he awoke neurologically intact and was extubated. that day he was transferred to the step down unit for further recovery. he was gently diuresed towards his preoperative weight. the physical therapy service was consulted for assistance with his postoperative strength and mobility. beta blockade was begun. chest tubes and pacing wires were removed per protocols and he progressed. he was cleared for home discharge. coumadin for his chronic atrial fibrillation was resumed and will continue to be managed by dr. as preoperatively. all follow up appointments were arranged, wounds were clean and healing well at discharge. medications on admission: allopurinol 300', lipitor 20', aricept 5/hs, lasix 80', toprol 50', ntg-prn, flomax
