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: history of present illness: the patient is a 74 year-old woman who has a history of a murmur, hypertension and aortic stenosis who was undergoing a preoperative work up for a left knee replacement and cardiac evaluation demonstrated worsening of her aortic stenosis. she underwent cardiac catheterization which confirmed an aortic valve area of 0.5 and two vessel coronary artery disease. she was evaluated by the cardiac surgery team and she presents for elective aortic valve replacement and coronary artery bypass graft. review of systems: she denies angina, shortness of breath, dyspnea on exertion, palpitations, syncope or edema. past medical history: significant for hypertension, degenerative joint disease of the left knee, hypothyroidism and aortic stenosis. past surgical history: significant for bilateral cataract removal. medications on admission: included atenolol 75 mg p.o. daily and synthroid 0.25 mg daily. allergies: no known drug allergies. social history: she lives with her husband. she is retired. denies tobacco or etoh use. family history: is noncontributory. review of systems: overall is in good health. denies any respiratory, cardiovascular, gastrointestinal, neurologic or hematologic symptoms. physical examination: patient is 4 foot 11 inches, 136 pounds, temperature is 97.7, heart rate is 68 and regular, blood pressure 148/70, breathing 15, 98 percent on room air. she is in no acute distress. her neck has no carotid bruits, no jugular venous distension. heart is regular rate and rhythm with a holosystolic ejection murmur with radiation to the carotids. lungs are clear to auscultation bilaterally. abdomen is soft and nontender. she has palpable distal pulses. laboratory data: on admission included white count of 7.4, hematocrit of 35, platelets of 305. bun of 13, creatinine 0.6. the remainder of her laboratories are remarkable for an ast of 46, alt of 12, alkaline phosphatase of 90, total bilirubin of 0.5, amylase of 108 and albumin of 3.9. preoperative chest x-ray demonstrated no congestion, no infiltrate. a preoperative carotid series demonstrated a left sided 60 to 69 percent carotid stenosis and a right sided 40 percent carotid stenosis. cardiac catheterization done demonstrated an aortic valve area of 0.5 cm sq, a proximal right coronary artery that was diffusely diseased, a mid right coronary artery that was diffusely diseased and a distal right coronary artery that was diffusely diseased. the proximal left anterior descending coronary artery and a 30 percent lesion, the mid left anterior descending coronary artery an 80 percent lesion and diagonal 1 with 60 percent lesion. hospital course: the patient on the day of admission was taken to the operating room where she underwent an aortic valve replacement with a 19 mm paracardial magna ce valve, coronary artery bypass graft times on with left internal mammary artery to the left anterior descending coronary artery. she tolerated the procedure well, postoperatively was transferred to the cardiac surgery intensive care unit. she was extubated, weaned off the drips and transferred to the floor on postoperative day #1. postoperative #2 she remained hemodynamically normal, afebrile, with benign examination and her chest tubes were removed. on a follow up chest x-ray there was evidence of free intraperitoneal air with no pneumothorax. general surgery was consulted due to worry of hollow viscous injury or diaphragmatic injury. abdominal ct scan was obtained with gastrografin area and this demonstrated extensive pneumoperitoneum but no evidence of bowel perforation. a small left pneumothorax and cholelithiasis with focal gallbladder wall calcifications and stool throughout the colon. she was observed with serial examinations, intravenous fluids and nothing by mouth. her examination remained benign and after 24 hours remaining stable. her diet was advanced which was tolerated and her examination unchanged. she also continued to receive physical therapy and at this point she is cleared to level 5 evaluation. her white count has been monitored and is currently 8.4. she has remained hemodynamically normal and now is ready for discharge to home. discharge diagnoses: 1. aortic stenosis. 2. coronary artery disease. 3. postoperative pneumoperitoneum without evidence of hollow viscous injury. 4. congestive heart failure. 5. gastroesophageal reflux disease. 6. hypertension. major surgical interventions: aortic valve placement with a 19 mm pericardial ce magna and coronary artery bypass graft times one. medications on discharge: lasix 20 mg p.o. b.i.d. times 7 days. potassium 20 meq p.o. daily times 7 days. atenolol 100 mg p.o. daily. synthroid 25 mcg daily. lipitor 10 mg daily. percocet 5/325 1 to 2 p.o. q 4 hours p.r.n. aspirin 81 mg daily. colace 100 mg p.o. b.i.d. follow up with dr. in four weeks. call . patient will follow up with dr. in two weeks, call -9204. patient will follow up with primary care physician in two weeks. she should call for an appointment. discharge condition: good. , m.d. procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery diagnostic ultrasound of heart open and other replacement of aortic valve with tissue graft diagnoses: coronary atherosclerosis of native coronary artery esophageal reflux congestive heart failure, unspecified unspecified essential hypertension unspecified acquired hypothyroidism aortic valve disorders osteoarthrosis, unspecified whether generalized or localized, lower leg hip joint replacement other specified disorders of peritoneum
